Redsn0w 0.9.8b7c Released Allows iPhone 3GS Users to Restore iOS 4.3.5 Stock Firmware
iPhone Dev Team has silently released an updated version of Redsn0w jailbreak tool, Redsn0w 0.9.8b7c. The Redsn0w 0.9.8b7c update is aimed for iPhone 3GS users only. It allows iPhone 3GS users with baseband 06.15 to restore stock iOS 4.3.5 or lower firmware. Redsn0w has a built-in fix recovery that will get you past the iTunes Error 1015 you’ll see when you try to restore to the stock 4.3.5 IPSW with a 06.15.
You may not be unaware of that Redsnw0w0 0.9.8b7c can also untethered jailbreak iPhone 3GS on iOS 5 Beta 7 or iOS 4.3.5, also old-bootrom iPhone 3GS owners can select choose custom logos, and/or verbose booting (for the really nerdy iPhone3GS fans out there!). Unlockers – If you have Ultrasn0w compatible baseband then you can also unlock iPhone 3GS running iOS 4.3.5 or iOS 5 Beta 7 (sn0wbreeze 2.8b7 doesn’t support old bootrom). So if you are stuck on iOS 5 Beta 7 and looking on how to downgrade iPhone 3GS to iOS 4.3.5 then download Redsn0w 0.9.8b7c available for Windows as well as Mac OS.
