The Importance of Saving SSH Blobs: A Guide to Jailbreaking and Downgrading Firmware
As an SSH blob can be simply described as the key to allow you to downgrade your firmware, it is crucial to understand its significance. When there are firmware updates, a lot of the time they're not jailbreakable immediately and they take quite a while to be compatible with certain devices. This is why having saved SSH blobs can be beneficial in such situations.
Before about a year or so ago, it was possible to downgrade your device freely by simply putting it into iTunes. However, Apple has put in place a system that makes it difficult for users to downgrade their firmware unless they have saved their SSH blobs. The major reason for this is that it prevents users from downgrading to lower firmwares without having the necessary keys.
The first method of getting SSH blobs is through Cydia, which is an essential tool for jailbreakers. When you have Cydia installed on your device, it will always pop up with a little thing that says "Should I let make my life easier? Go ahead." Clicking on this button allows Cydia to save your SSH blobs, making it easy to downgrade to any firmware at any time.
However, there is a more robust method of getting SSH blobs called Tiny Umbrella. This tool saves your SSH blobs on your computer, allowing you to use them with your device's SSH safe. With Tiny Umbrella, you can download and save your SSH blobs as soon as they are available, giving you the flexibility to downgrade to any firmware at any time.
However, there is a catch. To get your SSH blob using Tiny Umbrella, you need to be on the current firmware and have it signed by Apple. This means that if you want to downgrade to an older firmware, such as 4.0.1, you won't be able to do so because Apple has stopped signing those blobs. Therefore, it is essential to save your SSH blobs as soon as you upgrade to a new firmware.
Saving SSH Blobs: A Simple yet Crucial Step
Really, saving SSH blobs doesn't take that long, but many people are unaware of this simple step. It's crucial to understand the importance of having saved SSH blobs, especially since users can always have that choice even if they don't need to downgrade their firmware.
Staying Up-to-Date with Jailbreaks and Firmware Updates
The world of jailbreaking is constantly changing, with new jailbreaks and firmware updates emerging regularly. It's essential for anyone interested in jailbreaking to stay on top of these changes. This means keeping up with the latest news and updates, as well as being aware of any potential risks or issues associated with certain jailbreaks or firmwares.
When there is a new jailbreak available, it's essential not to update immediately. Instead, wait for the right moment to do so. Also, be aware of various little things that can get first-time jailbreakers in trouble. With attention and patience, users can avoid these common pitfalls and stay ahead of the game.
Conclusion
Jailbreaking and downgrading firmware can seem intimidating, but with the right knowledge and tools, anyone can take control of their device's software. Saving SSH blobs is a simple yet crucial step that every jailbreaker should be aware of. By staying up-to-date with the latest news and updates, users can ensure they always have the flexibility to downgrade or upgrade their firmware as needed. Whether you're a seasoned veteran of the jailbreak scene or just starting out, understanding the importance of SSH blobs and staying on top of the latest developments is key to enjoying the freedom that comes with jailbreaking.
 
                    
                        WEBVTTKind: captionsLanguage: enhey guys so today I'm here with a  jailbreaking frequently asked questions  video uh now since the new jailbreaks  are just around the corner I've decided  that right now would be a great time to  go ahead and talk go over some of the  more common and frequently asked  questions about jailbreaking uh now  obviously these questions are really  this video in general is not really  meant for the advanced Jailbreaker  somebody who's been around a while  however it's more focused towards the  novice Jailbreaker who maybe you've  never jailbroken before when you're  thinking about it or you've had  jailbroken maybe once or twice but you  don't understand everything about it so  if you think that you might you know  want to learn just a little bit more  about jailbreaking feel free to stick  around with the  video jailbreaking is the term used for  removing the Apple restrictions on your  Apple TV on your iPod touch your iPhone  as well as your iPad uh now jailbreaking  is kind of you know like a it kind of  interesting term um but that's pretty  much what it does uh now what what I  mean by that is take for example your  iPhone or whatever uh if you want to go  ahead and download an app customize  something tweak something everything you  do has to go through the Apple App Store  and to get into the App Store Apple has  to individually go through each  application so basically is a very  closed system only exactly what Apple  wants is allowed through now for some  people this is not a problem you know  there obviously are quite a few really  nice apps in the App Store everybody  likes the App Store however jailbreaking  through jailbreaking by jailbreaking  your device allows you to do pretty much  anything and everything you want uh so  instead of being limited by Apple and  what they think you're limited by what  your device can do uh so what this means  you can go ahead and download apps um  that maybe Apple doesn't like such as  Google Voice Groove Shark quite a few  others like that in addition to modding  tweaking pretty much doing anything and  everything you  want Cydia is the quote unquote  jailbreaking App Store uh now what this  means is that when you jailbreak  generally your device will look pretty  much identical to the way it was with  one key exception and that is the fact  that Cydia is now on your device Cydia  is for all intents and purposes an app  store for jailbroken applications uh so  the way Cydia Works however is quite a  bit different from the App Store as that  you can pretty much do anything you want  with Cydia it's just a groundwork uh so  using CD you can download paid  applications and yes there are paid  jailbreaking applications uh so quite a  few developers like to go ahead and  charge for their mods their tweaks their  applications which is totally fine  however the overwhelming majority do  give all the content away for free and  using CD you can download and install  pretty much anything you want in  addition City allows you to add your own  repository uh now what repositories are  is basically places where you store  software uh so with C you can go ahead  and add any repository and anyone is  free to make one so I felt like I could  do make my own repository put my own  custom app in there and then give you  guys the link to go ahead and add it and  then you could download through Cydia so  that really is the key difference  between Cydia and the App Store and the  fact that aot with Cydia anyone can  download anything there are pretty much  no restrictions whatsoever whereas the  App Store is very closed and very you  know narrow uh now when you do get Cydia  it's not like you lose the app store  either when you download Cydia basically  through jailbreaking it's the exact same  thing you can still have full access to  all your App Store applications so  obviously you're still able to buy all  the great games applications from Apple  however you do have a secondary source  to go ahead and download other sorts of  things that you cannot get through the  App Store  now there are two terms that are used a  lot with jailbreaking and this is a  tethered jailbreak and an untethered  jailbreak uh so this is really quite  simple if you have a tether jailbreak  what this means is that when you go to  turn off your device not just lock it  but actually totally shut it off when  you know you get the slide to unlock  then and then when it shuts off you will  not be able to boot it up by itself with  an unto the jailbreak uh so basically  what this means it's pretty simple is  that whenever you have it totally off  your iPhone iPod whatever when it's  totally off you will need to go ahead  and plug it into your computer and rerun  the jailbreaking software that you  originally jailbroke with now this is a  little bit of a hassle as it will take  you a few minutes every time maybe your  your device you need shut off whatever  you need to go ahead and plug it into  the computer and rerun it however it  will go ahead and boot up just fine um  but for that reason I really generally  don't recommend these these types of  jailbreaks as they get really pretty  annoying pretty fast as you have to deal  with plugging into the computer spending  a couple minutes every time your device  maybe runs out of battery you need to  restart for some reason so that gets  pretty annoying on the other hand an  unted jailbreak is pretty much exactly  the way it sounds you're free to go  ahead and turn your device on and off no  worries you never have to really run the  jailbreaking program again uh now these  days pretty much all major jailbreaks  are untethered uh tethered jailbreaks  used to be a thing a little while ago  but it looks like that they're kind of  becoming a thing of the past however  there are still a couple of untether or  rather teed jailbreaks  around now as far as this question goes  it really depends on you uh so the best  analogy I can think of is think of your  your iPhone your iPod your iPad think of  it as when you jailbreak it turns into a  small computer uh now obviously if you  have a desktop computer  uh when you have a lot of programs up if  you mod it if you tweak it a bunch it's  going to go ahead and slow it down well  the exact same thing holds true for your  Apple device uh so what I mean by this  is pretty simple uh just don't add a  bunch of stuff okay uh so obviously  that's the beauty of jailbreaking you  free to do as much as you want you want  to style every single icon redo every  little bit of graphics on the entire  device um run a ton of different you  know modifications tweaks you're  absolutely free to do this however you  are still limited by what the hardware  can do um so like I said it's the exact  same thing is if you take your maybe  your Mac or your Windows computer and  you make it video wallpapers and um just  you mod it like crazy sure it's going to  work but it's going to be very slow uh  so in general jailbreaking really  doesn't slow anything down it pretty  much a if you freshly jailbreak a device  it's really not going to be any slower  than what it what it was before  however when you do get to add a lot of  these custom apps tweaks themes and mods  it will slow your device down so what I  recommend is always to kind of if you're  going to download something always be  sure maybe if you don't decide you don't  really need it uninstall it keep your  device running nice smooth and  clean absolutely uh so take for example  my iPod Touch second generation now I'm  not even joking I probably Joe broken  this well over 100 times in the couple  of years that I've had it however all it  takes is for me to go ahead and plug it  into iTunes and press the restore button  and it is going to be 100% as good as  new uh that's one of the great things  about the way Apple has designed the  hardware in the fact that it is very  hard to go ahead and you know leave any  sort of data behind in fact all it takes  is just plugging it into iTunes like I  said and pressing the one restore button  it will go ahead and wipe everything out  on the device and restore it to a non-  jailbroken state so this is very handy  if for you if you would like to sell it  uh if you want to decide that you know  maybe jailbreaking is not for you for  whatever reason there's absolutely no  reason why you can't go ahead and go  back to a clean and un jailbroken  State no using a standard jailbreaking  program from one of the established  development teams you should never  actually totally kill your device uh so  the way this works is that Apple has a  very clever system in place that pretty  much prevents anything from actually  totally killing your device and it  actually is two modes one is called the  fu mode and one is called recovery mode  now I'm not going to get into exactly  how to enter these modes or anything  like that but basically do know that  these are safeguards that are in place  to prevent your iPod iPhone or iPad from  getting totally destroyed or breaked is  usually what it's called Uh so now there  can be a lot of reasons why you can have  problems now of course you know if you B  download a bad tweak um maybe there's a  glitch going on or in fact maybe  something more serious like you know  when you're in the middle of  jailbreaking your computer crashes you  accidentally unplug the device um there  are a lot of different reasons why  something could go wrong however there  should never be a situation where one of  these little problems mistakes actually  totally renders your device unusable uh  now there are several different methods  to go ahead and revive it from the dead  uh now the most common and the one you  absolutely should go for first is iTunes  all you need to do is take your device  plug it into iTunes and click restore uh  almost always you should be able to go  ahead and revive it it should go ahead  restore back to normal and you should be  just fine now in much rarer cases um  where that won't work then there are a  couple of other programs which of course  I'm not going to go ahead and get into  today um but do just know that assuming  that the hardware itself isn't busted so  you know as long as your iPhone your  iPod touch or your iPad is in good  working condition a jailbreak should  never actually go ahead and render it  unusable yes if you update your device  using iTunes it will remove the  jailbreak and this is something that a  lot of firsttime jailbreakers don't  understand and gets them into trouble is  that apple is constantly updating the  firmware on their devices now of course  this is a good thing because they  continuously fix bugs and add new  features however if you're jailbroken  you definitely need need to be very wary  of these updates so let's say for  example the laugh firmware update which  was 4.1 now the last working jailbreak  was made for  4.0.1 so a lot of people from  4.0.1 saw the update in iTunes and went  ahead and updated not really realizing  what they were doing now by updating  your device through iTunes it does  remove your jailbreak uh so this is  something that all jailbreakers need to  be very cautious of the best thing to do  is if you're jailbroken and you  obviously want to stay jailbroken ignore  the iTunes updates now every time there  is an update it takes the development  team quite a while to go ahead and make  a new jailbreak specifically for that  firmware now sometimes it takes less  time than others uh so for example  sometimes it takes almost no time in  fact sometimes jailbreaks just carry  over however the majority of the time if  you know there's a new firmware today  well it take might take the development  team a week a month several months to  get a new jailbreak out and in case in a  lot of the time you're going to be stuck  on that firmware and not have any other  options so that's why when you're  jailbroken always be very very worried  never go ahead and update your firmware  until the jailbreak teams goes hey we  have a new jailbreak for it and you have  the all  clear now this is one of the most  important things about jailbreaking  today as an SSH blob to put it simply is  the key to allow you to downgrade your  firmware now like I touched on earlier  when there are firmware updates a lot of  the time they're not jailbreakable  immediately and they take quite a while  so you always want to be able to  downgrade to lower firmwares uh now  before about a year or so ago you could  do this freely all you had to do is take  your device put it into iTunes and you  should be able to go ahead and downgrade  your device however Apple has put in  place a system that does not allow you  to do this uh so this is um this is  really annoying for a lot of different  reasons however the major reason is that  you just basically cannot downgrade  unless you have saved your shsh blobs uh  so like I said your an shsh blob is  basically the key to allowing you to  downgrade your firmware uh now there are  two different ways to get your shsh  blobs uh the first one is through Cydia  so when you have Cydia it always should  go ahead and pop up with a little thing  that says should I let make my life  easier go ahead always click that Button  as it will allow Cydia to save your shsh  blobs and at any point you can go ahead  and download the blobs from Cydia and  downgrade to that firmware it's a  fantastic feature and I highly recommend  that you go ahead and enable it now the  second feature which is a little bit  more robust and it's personally what I  use as well is called tiny umbrella now  I've done videos on it previously you  can go ahead and check out my channel to  see but basically tiny umbrella will  actually save your shsh on your computer  um now again this is great as you can go  ahead and use it with your s with your  shsh safe you can go ahead and downgrade  to that firmware no problem now there is  a catch however you can only get your  shsh blob while you are currently on  that firmware and apple is still signing  it so basically what this means is that  as of this video the most current  firmware for the iPhone and iPod Touch  is IOS 4.1 now let's say I don't have  any shs blobs and I want to go ahead and  downgrade to  4.0.1 well I cannot do that because  apple is no longer signing those blobs  so that is why it's imperative to go  ahead and save your shsh blobs as soon  as you upgrade to the firmware so really  pretty simple it doesn't take that long  but you would be I mean very very  surprised how many people do not know  how to do this so what highly recommend  every time go ahead and save as many  shsh blobs as you can because you never  know when and why you might need to  downgrade but by just simply saving the  blobs you always have that choice anyway  I hope that you found this little  frequently asking questions video  helpful in answering some of your  questions now of course there are always  new jailbreaks on the way um there are  always new updates on the way as well to  kill the jailbreaks so it's a constantly  changing game and you always really  should stay on top of it you know if  you're really into jailbreak and you  really like the freedom that it affords  you then really there's no reason not to  go ahead and pay attention you know when  there's a new update don't do it um when  there's a new jailbreak that's when you  update you don't update immediately um  lots of little things like that are very  important and get a lot of firsttime  jailbreakers in trouble however as long  as you know you just pay attention you  don't just you know start randomly  pressing buttons in iTunes you should  have no problem keeping right ahead of  the train uh so anyway guys if you do  have any questions you want to know  about anything about jailbreaking  including a full tutorial for pretty  much every single jailbreak that comes  out feel free to subscribe to my channel  uh like I said I'm really big into  jailbreaking and I always do go ahead  and post full tutorials pretty much as  soon as the jailbreak comes out so you  always have you know a little tutorial  go ahead and show you how to do it  usually it's prettyy simple but I like  to go ahead and help everybody out by  making tutorials anyway again hope you  found this helpful and thanks for  watchinghey guys so today I'm here with a  jailbreaking frequently asked questions  video uh now since the new jailbreaks  are just around the corner I've decided  that right now would be a great time to  go ahead and talk go over some of the

to  4.0.1 well I cannot do that because  apple is no longer signing those blobs  so that is why it's imperative to go  ahead and save your shsh blobs as soon  as you upgrade to the firmware so really  pretty simple it doesn't take that long  but you would be I mean very very  surprised how many people do not know  how to do this so what highly recommend  every time go ahead and save as many  shsh blobs as you can because you never  know when and why you might need to  downgrade but by just simply saving the  blobs you always have that choice anyway  I hope that you found this little  frequently asking questions video  helpful in answering some of your  questions now of course there are always  new jailbreaks on the way um there are  always new updates on the way as well to  kill the jailbreaks so it's a constantly  changing game and you always really  should stay on top of it you know if  you're really into jailbreak and you  really like the freedom that it affords  you then really there's no reason not to  go ahead and pay attention you know when  there's a new update don't do it um when  there's a new jailbreak that's when you  update you don't update immediately um  lots of little things like that are very  important and get a lot of firsttime  jailbreakers in trouble however as long  as you know you just pay attention you  don't just you know start randomly  pressing buttons in iTunes you should  have no problem keeping right ahead of  the train uh so anyway guys if you do  have any questions you want to know  about anything about jailbreaking  including a full tutorial for pretty  much every single jailbreak that comes  out feel free to subscribe to my channel  uh like I said I'm really big into  jailbreaking and I always do go ahead  and post full tutorials pretty much as  soon as the jailbreak comes out so you  always have you know a little tutorial  go ahead and show you how to do it  usually it's prettyy simple but I like  to go ahead and help everybody out by  making tutorials anyway again hope you  found this helpful and thanks for  watching
