G920I 6.0.1 Modem not found - GSM-Forum

jcdes · 10-04-2016, 20:14

Phone has service I was able to backup everything but at the unlock screen I hit read codes or unlock and says "Modem not found". 26.9 Tool version...

jcdes · 10-04-2016, 20:50

Do I need to downgrade modem?

jcdes · 10-04-2016, 20:56

Downgraded to OJ6 modem but did not work.

Phone screen has to be on for it to work. Does modem show in Device Manager. Sometimes a simple reboot does the trick.

jcdes · 10-04-2016, 21:13

Yes modem shows in device manager, screen is off... Let me check that...

jcdes · 10-04-2016, 21:15

Gonna reboot and see if that helps, phone is rooted, modem downgrade did not help. It does cert backup just fine and shows all info. I'm stumped...

jcdes · 10-04-2016, 21:29

Nothing... Phone security patch level is May 1, 2016.

jcdes · 10-04-2016, 21:42

Kept trying until it worked. Should I upgrade the modem again to the 6.0.1???

jcdes · 10-04-2016, 21:50

I'll leave it like that it's working fine...

jcdes · 10-04-2016, 22:53

My IMEI was ok an serial number was ok, never got damaged but I always backup before doing anything, I rather spend a few more minutes doing that in case something goes wrong...
