I give up, please help. 3GS stuck in DFU, Can't Restore.
New to the Forum, so please forgive me if I post this in the wrong area.
Also, yes, I have searched the forum and almost every other site for the answer to this question.
I have an Iphone 3GS (new bootrom) 4.3.3 with 6.15 baseband. I know this, because I successfully restored it with a custom FW.
However, it got stuck in DFU, and I cannot get it out.
I don't know what was one it before, because it was given to me in DFU. All the guy told me was it had a 6.15 baseband on it, so I assumed 4.2.1.
I couldn't fix the phone as is, as it was stuck in DFU mode as well.
I decided to update to 4.3.3 with 6.15 with a custom firmware, as I heard that was quite successful in my situation.
It went through succesfully, I was excited, as the guy said I could have the phone if I fix it. However it went back into DFU mode and wouldn't come out.
Mind you, I don't know how to make my own custom firmware, so I have been using ones I could find.
I was told by someone to use iFaith to grab SHSH files and make a custom firmware with that.
I did that, and it came up with error 37. That is in PWNED dfu mode. Error 1600 with just regular DFU.
I am stuck now.
Can anyone give me some guidance on this, I am willing to try every step someone gives me and give full detail of what happened during their process. I just really want to get this fixed.
