TinyUmbrella has been updated to 4.00.49 and can now save SHSH blobs for iPhone 4 running iOS 4.0. Saving iPhone 4 SHSH blobs for iOS 4.0 is important because when Apple releases iOS 4.0.01 firmware for iPhone 4, you won’t be able to downgrade to 4.0 unless you have SHSH blobs for iOS 4.
Since there is no official jailbreak out for iPhone 4 yet, saving SHSH blobs via Cydia's "Make My Life Easier" option is not available yet for iPhone 4 users. Here is when TinyUmbrella comes in handy. See the important information below before proceeding:
IMPORTANT:
- Apple stops signing firmware SHSH once a new firmware is out. Once Apple has stopped signing firmware SHSH requests for a firmware version there is no way to get your SHSH for that particular version.
- Device does NOT need to be Jailbroken in order to save SHSH blobs with TinyUmbrella.
- Your iPhone 4 MUST be connected to the computer to save shsh blobs. For other devices, you can also save SHSH blobs without connecting the device simply by providing ECID.
- If you desire to restore your iPhone 4 to iOS 4, make sure you uninstall Wi-Fi Sync before trying to do so. I’ve apparently had the same issue a few other folks had.
- So far restores on the iPhone4 are not perfect. They error out locally but the restore does complete – it just needs to be helped along. (Much like downgrades where the baseband update fails). Hopefully this will all be resolved soon.
- You can also save ECID SHSH blobs for iPhone 3GS, iPod Touch 3G and iPod Touch 2G (MC).
- Your files are saved in:
- MAC
/Users//.shsh
ex: /Users/semaphore/.shsh - WINDOWS XP
<Main Drive>:\Documents and Settings\\.shsh
ex: C:\Documents and Settings\semaphore\.shsh - WINDOWS 7
<Main Drive>:\Users\\.shsh
ex: C:\Users\semaphore\.shsh
- MAC
