3gs Stuck in Recovery Mode - Tried Everything I Know of

[pinkerton]

Please help with 3GS

I bought the phone from someone who had no history, just told me that it gives error 37 when you try to restore from iTunes. I tried to restore from iTunes and got the error 37

I tried downloading an older iOS and do shift + restore which gives me error 3194

I tried to “fix recovery” with Tiny Umbrella, after setting TU to compatability w/XP and set as administrater, and I get the log below:

If I try to boot with Redsnow I get this:
Missing keys.plist data for this build:
Device: iphone 3gs
ECID: 3069577819599
Build: iphone2,1_6.0.1_10A523

If I try to fix this by pointing Redsnow to iOS 6.0 (like some say to do) and running “just boot”, then I got a short look at a pineapple (freaky) and then nothing
After all the messing around above, I tried to restore in iTunes and got error 1600
This phone has the new boot version
Please help with 3GS

You can't downgrade to a lower iOS version without blobs, and as TU pointed out, you don't have any iOS blobs to save. Attempt to restore using pwned DFU mode with RedSn0w using a custom IPSW. Stitch one with RedSn0w to preserve the baseband and see if that fixes it.

Anther scenario would be that the previous owner used sn0wbreeze to jailbreak the 3GS. Try using sn0ebreeze and de-select all the custom boot logos and recreate the IPSW

Thanks for the advice, yet I was not successful. Here's what I did:
Opened redsnow and tried to "query" for blobs for my ECID - a screen popped up titled "Available remote blobs" and remained empty. So I tried sn0breeze, yet don't see any option for "de-selecting custom boot logos". Can you suggest anything else?

If that's not the case then it'll be a hardware error. Most likely the baseband chipset.

Thanks for the input. Do you know how I can confirm it's a hardware issue? Is there any test, or diagnostic tool I can run?
