IMEI null, Service Mode Blank, Baseband Unknown
I have a Canadian S4 (SGH-M919V) from WIND Mobile that my friend gave to me, broken.
I have already tried just about everything I can think of, and everything I read online to repair it.
It has a NULL IMEI (as verified by doing *#06#), and when I enter the Service Mode menu via *#0011#, the menu screen comes up but is just black and blank. The Baseband version displays as "Unknown".
I have tried flashing a few different stock roms (via Odin) for that particular phone, and have even tried AOSP roms (via TWRP), to no avail.
I have followed guides for restoring a blank IMEI, however, all the methods I tried required a working Service Mode, which I do not have.
At this point I'm thinking the problem is either hardware, or, it needs to have the IMEI reset via the JTAG, and I don't have the stuff to do that.
Any suggestions would be greatly appreciated!
Thanks in advance!
