SM-G925F S6 Edge No Modem Found

[gers1980]

Hi

I have been at this for weeks and decided to see if I could get direct help.

G925F
I'm on Android 7.0 at present But have tried downgrading to 6.01 with similar results. I have also tried flashing lots of different modems and different versions of Samsung Pro Tool

Now im back on Android 7.0 via 4 flash recovery files.

Problem is No Baseband/No Imei/No Sim detect and Z3x is detecting no modem???

I'm starting to think this could be hardware related.

Please see logs. Thanks for any help....

According to your log, you have corrupt efs.
Write new efs and repair imei thereafter.
If not work, then check hardware issue.

Downgrade to 6.0.1 and flash modem .

Thanks Guys.

Tried the 2 modems same deal.

Ive downgraded to 6.01 and flashed modem in the past also.

Regards repairing the EFS how would I go about that???

I'm on 7.0 and I have no EFS Backup for this phone.

Would a corrupt EFS stop Samsung pro from reading the Modem Board id???

Thanks

Android 7.0 root. Flash to phone in AP with Odin or z3x
Go to backup tab in z3x tool
Backup efs by performing 'read efs' operation.
Go to repair tab and perform 'reset efs' operation
If problem not solved, write new efs under backup tab.

So just flashed EFS still same problems no Baseband/IMEI/Modem detected

Also getting Security Damaged now as above?????

Thanks

[Kwesi_Roy_GH]

Your problem is hardware issue.
You can write back your default efs in this location C:\Program Files\Z3X\Samsung\SamsungToolPRO\backup\EFS.

[gers1980]

Really Disappointed........ Thanks

[gers1980]

Before I strip down the phone and reheat the Basedband/Shannon ic.

Is there anything else I can try to rule out software/flashing issues.

Thanks

[zapped]

Reset EFS see if that brings back the modem
