I am really hoping someone can help me sort this problem. I recently bought a LG P970, and after long await from customs, i received it! On day 1 before even purchasing a simcard i rooted and changed roms. I went through all sorts of roms from nightly cm7 to cm10, nove, aokp etc.. I finally decided i like AOKP Rom and day 2 bought my sim card. SUPRIZE!! no network! IMEI unknown. Unfortunately i was to ignorant to do a backup and i have been searching for +- 40hours now to try resolve this issue.
I have tried the tutty/Hyperterminal.. Does not work! If i dial 3845#*970# and access the hidden menu. as soon as i select CP USB, the pc just makes the insert/ takeout sound constantly and does not install driver, but on AP USB, the sd card can be accessed, my device shows on system and everything is 100%. I have tried this on 2 windows 7 computers. So that option is out.
Does anyone know another way to restore the IMEI? I dont have any fancy box tools, just my pc.
This is the Optimus G forum. I'm on the phone app so I can't send you the link for proper forum, sorry..
Good luck.

Hello you guys!
I just received my lg g7 g710ulm. And when i turned on the phone i understood that im not lucky.. I need your helps! Please! Because i cant do it myself.
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.
3. Looks like gps not working too.. But tried only in indoor.
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 can't return phone to shop because im living in different country But phone is amazing! And I loved lg. I had lg optimus one (was lost and back by good people), then lg optimus black(was burned in bonfire), lg g2(left in taxi), lg g6 (was lost) and finally lg g7. Yeah, looks like something wrong with me or these lg.. But i love it
Did you put in your SIM card first before you started...
I read you need to insert sim first but could be wrong.

Sure, i did it. Anyway don't search networks. But what carrier of sim card and numbers into sim card, phone can recognise.
Maybe i wrote not understandable? My english not first language. So asking. I will try to explain.
Thanks for your reply.
I uploaded a log file with errors but cant to write here link, because i need 10 messages
My G710ULM's GPS stopped working 2 days ago, still trying to find out what's the cause of it. Tried apps like GPS Status, GPS Locker, no avail that it isn't picking any satellites at all. Just searching for GPS location. Restarting the device haven't helped either. In settings I even excluded all apps in Power Saving Exclusions. In GPS Status app, resetted and downloaded the A-GPS, this should surely make the GPS work. No success.

Hello expert. I have an LG G7 ThinQ ULM phone. The problem of this phone is no phone waves signal, 3G, 4G. (a week ago that is good). I think that because the SIM and insert this SIM into other phones, this SIM still works very well. So can you show me how to fix it? Thank you very much!
Note: I was try as below but not success
Go to the Home screen;
Tap on the Phone app;
Switch to the Dial pad;
Type in (*#*#4636#*#*) and just wait – the phone should automatically redirect you to the Service mode;
Once you’ve entered this new mode, tap on Phone Information or Device Information;
Tap on Run Ping test;
Look for the button labeled as Turn Radio Off and select it;
Wait for the phone to restart;
Tap on reboot.

hi, i need help, same mistake, i dont get a solution
Hi guys, I bring a solution to this problem, I found this topic: https://forum.xda-developers.com/t/no-signal-after-crossflashing.4089281/, you understood better by reading yourselves, but basically I flashed the rom with lg up chip erase mode and my wifi/data started working again, I know this is not recommended under any circumstances but it worked for me.
However, be aware that ChipErase mode not only erases IMEI numbers, but also erases MAC addresses, EFS partition and others. In many countries if your device does not have an IMEI number or other identifiers, SIM networks cannot allow (my case in Brazil it worked) for you to register with them, i.e. in most cases your sim will not work on the phone and you will not have cell service. You may still have issues with WiFi networks as without MAC addresses your WiFi will be grayed out or the network may not allow you to connect. Also, be aware that in many countries around the world knowingly tampering with or changing your phone's IMEI numbers is against the law. IMEI number is how networks and ultimately law enforcement identify the device and its owner
