Details : The battery was at the end of its life , it couldn't bring enough power to the baseband chip.
█►► IMPORTANT : ◄◄█ == After replacing the battery you'll need to flash the BB to 06.15 again or if you had stock BB then do a simple restore
_______________
Hi, I just bought a used 3GS from Ebay , it was stuck on Recovery Loop , I fixed it.
But then when I started to use the phone , after 3min of use , it will restart by itself. No matter the firmware (tried many versions + jailbroken/non jailbroken ...)
I think it's an hardware issue , what do you suggest me to do ? (I already took it apart , visually seems OK , all connectors are there ...)
Noticed that it will also reboot by itself in recovery mode too but not during restores
ADDITIONNAL INFO : No matter if it's plugged or not , the reboot problem occur
Didn't notice but the baseband seems corrupted 06.15 failed , wifi greyd , bluetooth too . I'll try changing the battery but it might be baseband corruption causing the phone to reboot .
The corruption is software , I might be able to fix it ?
- Random reboot + No IMEI / Wifi etc look : http://www.youtube.com/watch?v=tcrxZh_li...

I'd take a look at the battery... it may be that it is not compatible in some way with your phone, or it is at the end of it's life. If the phone doesn't reboot when plugged in to the wall charger then this makes it a bit more clearer that it is the battery. (if you are testing/chargin
try replacing the battery first and then see how you go. the only other time I have had something like this was a power button that was sticking.. does the phone actually boot to the home screen and allow you to use it before it crashes?
Added new info , i'll order a battery to see if that can solve the issue (for some it had *other forums*). Battery or baseband failure , I hope it's the battery :(
Oops... You did the iPad 6.15.00 jailbreak?? Or the person before did this? It would be why wifi/Bluetooth are greyed out, I'm not sure if it wipes imei too.
The person before , I wouldn't have done it , i'm not that mad . Is the battery voltage too high ? Restore log : http://pastebin.com/ypfw1Bhc

Restore with the 4.2.1 custom file. first start the tiny umbrella then put the custom file into itunesby holding shift button to restore. after restore check the imei if have then no problem. if imei= unknown then its very difficult to rebuild the phone have to change the logic board.
yes u have corrupted baseband. it will very difficult to recover but can try to do all these steps may be it will recover. put ur phone in dfu mode then restore by red snow with installing ipad baseband with orignal file. means put the orignal file in redsnow then tick on ipad baseband. then start. may be help you.

there are NOT several reasons for this (imei bluetooth AND firmware missing): It means you or someone with your iphone upgraded to the ipad baseband (6.15.00) using redsn0w in a failed attempt to unlock the phone for other Sim Carriers, and your iphone was made after week 128 (after 28th week in 2011). this is mostly the new 8Gb 3GS. Your phone is now useless because the baseband chip is deprogrammed. You will not be able to EVER install ANY baseband on these new chips again. I have heard the chip can be replaced by a process known as reflow resoldering but I have yet to see this repair done. Does anybody know the retail value of phones in this shape?
Dear Erik, My phone is an iPhone 3GS 32GB. Made in 2009 37th week and I have these issues ie.(No IMEI,No ICCID, No WiFi, No Bluetooth etc.) Since its made in 2009 37th week, I believe my phone would not be on the Toshiba Chip. I am a beginner when it comes to technical aspects on an iPhone. Is there any way to fix my iPhone?

My 3GS had the same symptoms after installing the ipad modem firmware, even after downgrading. Phone was rendered useless, rebooting, no wifi, not responsive, etc. Thought it was bricked for good.
Desperately I did a restore as new from itunes to IOS6 and new firmware 05.16.07, now everything is working as new! Needless to say I am relieved. Now will seriously think about it before attempting to jailbreak/unloc

Tom,
Hi Victor also I am having this issue regarding the original battery .. did it ever show any signs of dieing out ? was the only way to remove the battery and replace new .. can you also tell me how do you think you left out the battery from the board before you placed the new/old battery back and everything worked? cheers also do you recall your orginal battery part number vs your replace part number too please thanks alot
mick,
Well, I read all the answers over there, the battery is not the problem, it is the new basband, any 3gs 8GB that has the serial xx135 and up will have the same problem when flashed with 6.15 ipad most likely will act the same, and the only remedy is to flash the baseband again, but that would not really help, but it might. However, you can wait and hope that Apple release a baseband version higher than 6.15, or some iphone savvy guy find a remedy for this problem.
nidal,
