LG G7 No signal, no wifi, no gps - GSM-Forum

k3x1s · 03-12-2019, 00:18

Hello to everyone! Looking for help!
I just received my lg g7 g710ulm. But found there heavy issues:
1. No signal. Don't search networks. Immediately getting error when trying to do it myself. "Preferred network mode" can't change due error and it showed "null". After reflashing it's now showing "22".
2. Don't see any wifi networks. But access point is working and other devices can see me.
2.1 I found that wifi going to work then i tried to use gps. After few seconds phone starting see wifi networks and connecting. If turn off wifi and turn on again phone don't see networks and you need to repeat procedure with gps.
3. Looks like gps not working too.. But tried only in indoor. Maybe outside gps will work.
I can't understand is it software or hardware issue. Maybe seller changed imei number and model by firmware and did it wrong? Antutu showing strange imei.
Can i to know somehow real model of phone? I can try to make logs and attached it here. Or maybe somebode can check imei, bands with octopus box? I dont know what to do

P.S. Bluetooth is working. Tried to send file and it was fine.

I bet it is a demo unit (G710V) flashed to G710UL

How do you know your IMEI is clean? You just said it was NULL. Open the back, does the motherboard have a small black coaxial cable? If not it is a demo unit with no modem IC.

And where can i check IC modem? Where is it placed?

Look at the long thin part of the motherboard, there will be a coaxial cable. The demo G710V doesn't have that cable. If it has IMEI then for sure is not demo model
