[aznbeayst]

I have a phone that I pretty much think the BL is bad/miss/corrupt, tried many methods, and no luck, If I just bought a new commboard will this fix my problem

[nitant]

Yup a new commboard will fix all your issues.

Of course that is if your mainboard is working fine

[aznbeayst]

What does the main board do/contain?

[aznbeayst]

can anyone else please confrim. i dont want to spend $150 and still not have the phone working... my problem is that i have a repair needed error and ive tried everything like a17 testpoints and keep coming up with errors and spamming at, and bootloader issues.. if i buy the commboard this will fix my issues?? also, is commboard same name as logic board.. thanks ahead

[drg]

No, logic board and comm board are different.

Yes a new comm board will fix your issue.

hi,

on the picture is the logic board, the commboard and the battery.
this is more than u need.

picture taken from www.ifixit.com
at the top is the commboard und at the bottom is the logig board.

if the price is good at the end of this auction i would buy and sell the parts on ebay which u dont need.
keep in mind that u would pay 149 $ ONLY for the commnoard on ifixit.com.

The commboard is that one on the top with he metal shield. The guy is holding with his right hand.

[aznbeayst]

ok thank you that is what i thought.. according to the auction, the guy says logic board but pictured was the commboard which made me confused... anyway, i just lost the auction within 10 sec.. damnit.. i think ill just sell my broken iphone for 250 and pay out of pocket for a brand new one..

[point_01]

so is there any soldering needed to replace the commboard?

[aznbeayst]

so is there any soldering needed to replace the commboard?

i think only the 3 wires to the battery.
www.ifixit.com has step by step instructions

it look slike the battery is connected to the logic board and not the comm board?

[ikuwara]

if u can open up your iphone, why not do A17 testpoint to fix the bad bootloader???

If your iphone got NO WIFI/BT/IMEI, it is not the problem of your bootloader. It is the eeprom(invalid calibration data)...

Thanks...

[aznbeayst]

ive tried, stuck at spamming AT

[ikuwara]

It is a good news if your iphone stuck at "spamming AT"...

There are some guideline for spamming AT... start from step number 5
