The modem must be readed before write Cert file.
So try first full flash with 4 files, if not solved try flash with Smart switch.

[haythem85]

tried 4 flash files. tried smart switch. tried everything. nothing still blank.
downgraded modem with u1 u2 rom modem still nothing.
used combination modem file still nothing.
phone is working but baseband and imei unknown.
anything else i can do?
in download mode i can see product SM-G928F. FRP LOCK OFF.

[blang]

flash last version of firmware.
if modem still not run, then can be hardware problem.

[haythem85]

BEFORE anything, let me explain 1 thing:
Basically i got this phone for almost free. PHONE IS ORIGINALLY G928T. Previous owner changed the logic board (dont know for wt reason) and installed G928F logic board on it. everything else is G928T. charge dock and antenna and case and screen.
Phone started and run but its like Tablet (no Phone) cant access *#06#, cant access *#7284#. no service codes work.

i flashed it. same. i flashed 7.0, 6.0.1, COMBINATION 5.1.1 (cannot use it, no root)
went back to 6.0.1 (lowest available for my phone) and tried flashing cert and nvdata
(i flashed u1, u2,u3 modem file from diff roms (G928F) nothing help.
my baseband imei null.
below all logs for ALL TASKS: (hope i get help)

Try flashing back 7.0 modem, why downgrade to 6 anyways?

Check your MIPI, make sure its still reporting PASS

Also learn to use the google search function, the please bro sh*t is nothing new but weekend unlockers need to be more humble and learn from previous postings.
How have you been on this forum for a while now and yet still not learn to use search function?

P.S. clangsm has answers also
