Hi, I created the custom 4.3.1 restore file for my 3GS using Pwnage and entered DFU mode. However, when I started custom restore in iTunes I received error 36. My phone rebooted and appears to be fine, but I'd like to solve this problem so I can use some apps that require 4.2+.

Details:
2008 Macbook Pro, OSX 10.6.6. Direct USB connection to phone.
iTunes 10.2.1 (1)
3GS on AT&T 7.0, model MB718LL, iOS version 4.0 (8A293)
Was jailbroken using the slide-to-jailbreak site (friend did it, can't remember name.) I had tethering, SSH enabled but not used, a couple Cydia apps downloaded, etc. Didn't do anything strange.

Logs: iOS jailbreak log - Pastebin.com

Really appreciate any help.

Can you still restore to 4.0 (assuming you have saved SHSH?)

The log suggests a problem with the NAND (which might not be able to be fixed via software). Also have you replaced the battery at all?

To my knowledge, my 4.0 SHSH was not saved. The aforementioned friend simply slid the bar on the slide-to-jailbreak site. So, I don't believe I can restore to 4.0.

When you say there is a problem with the NAND, you are referring to the 32GB memory chip and in what way? Everything about the phone works fine, as far as I can tell. What software fix do you recommend trying if you recommend that route?

I have not replaced the battery. The phone has never been opened.

Update:

I have tried to restore to the pwned 4.3.1 restore file on two different MacBook Pros. The same error 36 occurred on each one. I tried inserting the line "74.208.10.249 gs.apple.com" into /etc/hosts, but the message was the same with or without this line.

I have also tried te restore to the official 4.3.1 download from Apple, and this did not work. One time I received, I believe, Error 1606, and the other time I want to say it was 1645. I'm sorry that I didn't catch the specific numbers. We didn't think we did anything differently. I've asked the person who owns the other Mac for the logs, and I'll update this thread when I receive them.

So, current status is that I cannot restore my phone to a pwned or official restore file, meaning I'm stuck on 4.0 unless someone has a bright idea.

Yes the NAND is where your OS, music etc is stored. Just because you have no problem before doesn't mean that the NAND couldn't suddenly fail.

If you don't publish each the failed restore logs that produce a different error message we can't help you.

I see. How would you suggest I test the NAND for failure?

I have obtained the logs from the attempts to restore pwned and normally to 4.3.1 on the second MBP. iOS jailbreak log continued - Pastebin.com
