^= Click on this 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/charging using the pc then the power supply is fairly low compared to the ac outlet)
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.
It sounds like a corrupted/bricked baseband. You’re best bet would be to flash the iPad baseband, and hope that it works.
if your 3’rd 4th and 5th serial number are higher than XX128XXX, and you install the ipad baseband, your wifi, imei, and bluetooth will be gone.
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?

having similar problem every 5 minute reboots my back light went out thought it was lcd because i had a incedent with water but after i got the battery 50% power the light came back so now im wondering if i dont need a new battery too hoping this will fix dont want to restore but ****also message keeps popping up at random indicating this iphone is not optimized for this accesory any suggestion/ help much appreciated!!!
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/unlock it again.
mine was flashed ipad baseband and its restarting after 3 min i downgraded basebandit but is the same, i checked the baseband chip it is old one 36MY1EE so it cant be the baseband damaged it. i’ll try changing battery tomorow Update it was the battery, now it works perfect :)
