ive been trying to fix this phone. at the moment it has no baseband and ofcourse no IMEI I tried to do drk repair and I tried to wipe efs and uart never connects I'm not sure if its cause of the baseband. I already flashed latest software in phone through kies and I still don't get baseband. I also flashed nv from another phone along with efs and still nothing. has anybody been able to fix unknown baseband? here is the phone info.

make sure screen stays on through the whole process

lizard_king2612 · 01-26-2016, 21:46

thanks to everyone who replied....no still no baseband no imei at all....

ive been trying to fix this phone for a month..i tried 3 other boxes and I was hoping gcpro would fix it, but for some reason uart just wont connect , screen stays on all the time.
I'm about to give up on this thing......can someone provide me with an eng sboot? that's the last thing ill try.

gayansuranga · 01-27-2016, 04:38

why don't you check hardware.. I read your posts It must be a hardware issue. start from Rf section you"ll find an answer for sure, and by the way I'm afraid even if you try service commands after writing a sboot will not help you to solve this,

I am experiencing the same problem with my SM-G920T. I have a GCpro Key (active) and ordered the FIDI addapter as well as both UART clips. Neither seems to work. When I try to run any program using the UART mode it fails. The program starts and indicates device detected, then after a few minutes fails indicating device not found. I also note that the DRK repair program says to dial *#7284# and set the phone to UART>PDA mode. This dialing sequence does not bring up any menu to set the phone. Another thing I see is that both UART clips have a slid switch to set what looks like a buffer size. How do I determine which setting is correct for my phone?

When you say to check the hardware are you indicating the phone hardware as in disassemble and physically check it. If I dial *#0*# those tests all run fine with no errors. My IMEI is showing null and my baseband appears normal.

Any suggestions before I just throw the phone in the incenerator?
