is downgrade 4.3.5 to 4.3.3 possible??
Can one of you experts confirm something for me? I'm running a tethered 4.3.5 and want to downgrade to 4.3.3 so I can have an untethered jailbreak. The problem is I only got the phone when it was on 4.3.5 so don't have saved shsh blobs from previous firmwares. I've read on a few different place that it can be done by the method below but I'm not willing to try it till someone who knows what they're talking about confirms that it actually works. What do you lads think?
"How to Downgrade iOS 4.3.5 Without SHSH blobs saved ? We showed you before that How to downgrade iOS 5.0 to 4.3.3 in General we didn’t put to you if it works on Iphone 4 or 3GS or Ipad 1, 2 but now our reader George Father comment on our previous post that he successfully able to Downgrade iOS 5.0 to iOS 4.3.3 on Iphone 4 and see the steps without error. Only tested on an iPhone 4 and 3GS – to successfully downgrade to 4.3.3 from 5.0:
How to Downgrade Iphone 4 4.3.5 without saved SHSH blobs files Tutorial :
Step 1: You have to go to “C:WindowsSystem32driversetc” , and replace “HOST” file with the downloaded one in “Restore Files” folder. ( Restore files here –> LINK )
Step 2: Open Redsn0w 0.9.8b5 for Windows /Mac ( LINKS ) and Jailbreak your device but you have to point to iOS 4.3.3.
Step 3: Open SnowBreeze 2.7.3 ( LINKS ), choose expert mode, then create pwsd (i think its what is called) allow it to do what it does, then just follow through the on screen instructions.
Step 4: It will now be in Pwned DFU Mode
Step 5: SnowBreeze will have saved the custom 4.3.3 firmware on the desktop, load up iphone, it will prompt you to restore, on windows press shift and click restore – this will browse to a file of your choice, choose the one on the desktop.
Step 6: This will downgrade your iphone through iTunes it will boot up with a fully restored iphone.
Step 7: Create a custome 4.3.3 restore with Sn0wBreeze 2.7.3 ( LINKS ) (i went with expert mode and didnt change any options)
Step 8: Enter Pwned DFU Mode through Sn0wBreeze
Step 9: Run Tiny Umbrella and start the TSS server.
Step 10: load iTunesand start the restore process with your custom restore file.
Step 11: Now you are on Iphone 4 iOS 4.3.3 and you able now to use JailbreakME 3.0 – UnTethered Jailbreak."
No. It is not possible to downgrade to 4.3.3 from 4.3.5 without SHSH blobs. None of the instructions provided will bypass the SHSH requirement. Unfortunately, without SHSH you can only restore to the latest iOS revision. Most sites that post downgrade instructions are either exploiting extremely small windows of time where both iOS revisions are being signed, or more commonly, just aren't actually intended to work.
The preceding forum post has been brought to you by the letter "N" and the number 42.
iPhone 4, 32GB (iOS 6.1.2 | evasi0n | SHSH: 4.0 - 6.1.2)
