You formatted your phone's IMEI with SP Flash Tool. Use this thread to restore your IMEI (second post)

Problem to reading sim card in LG G4 (h540)

Hello , my lg g4 had a problem to reading sim cards , I decided to flash my phone with octaplus pro box and everything worked perfectly in the first boot , the sim card reader read my sim card correctly but after restarting my phone I saw a weird thing my network has been disabled and my phone's IMEI had gone . I tried to flash another firmware and again everything was right in the first boot , but whenever I restart my phone the IMEI will be null and sim card reader doesn't read my sim card .
it seems a weird problem , I tried to flash 5 firmware and every single of them has the same problem . I don't think this is a hardware issue , but if you think it is I would be really appreciated if you could help me to fix my phone.
for additional information I should tell I flashed ".kdz" format and I didn't find the .tot file for H540 . BTW what is the problem of my phone?
thank you

You should disassemble the phone and see if something has gotten inside the sim area.

Hi Raja, I can't speak to the SD card (because I don't have one in my phone), but I had something similar happen to my sim yesterday, when I ejected the sim carrier.
Before I'd consider taking apart the phone you might consider a shim for the sim. I used a piece of paper under the sim to push it up and make better contact with the "pins" of the sim socket. Working fine now.

Check if the device detects other SIM card, to discard that the SIM trail is working.

I checked other SIM and it is working. I guess I have issue with my SIM then.
But after flashing ROM, I am getting this:
I hope you didn't format all, otherwise, you'll lose your calibration data, IMEI and more. If the device is detecting a different SIM, then your SIM is the issue, you can change the SIM card from your provider, the surface might be scratched.
flash nvram and nvdata file
