Hello - trying to update my iPhone 3gs to iOS 5.0.1 using the newest version of redsn0w to create a no-baseband, old bootrom custom ispw (trying to preserve baseband, which is currently 6.15.00, since I'm afraid updating this German-purchased GSM phone will cause my US AT&T SIM to quit working on a standard restore & jailbreak in the US). I created the ISPW without issue, and put the phone in pwned DFU mode without issue. I first run tinyumbrella (current version) and start TSS server to fetch signature. iTunes detects the phone in recovery mode, and goes through the restore of the custom ispw and reboots.
However, the ISSUE is that upon reboot, iTunes merely continues to detect a phone in recovery mode. Cannot boot or exit recovery using redsn0w or tinyumbrella - redsn0w results in a "device does not support untethered options" error. Cannot do a standard restore through iTunes (non-custom ispw), because it kicks out the error "iPhone not eligible for requested build".
Please help! Is there a way to get the phone to boot up as it is, or am I better off just trying to restore to one of my saved SHSH blobs at iOS 4.3.5? Is preserving baseband even an issue for me, if I am trying to use a phone that was not sold by AT&T (bought in Germany), but is a GSM in the US that I am trying to use with an AT&T SIM?
Thank you very much for your help.
I will help you restore if you can somehow also give me the 4.3.5 blobs because I'm stuck with bb 4.11.08 and I desperately need them (Cydia doesn't have them)!!!!
Please reply if you can give them to me I'll help you restore 100%!!
