If you have restored the backup properly, just try to factory reset the firmware...
Which method you had used to backup and restore EFS?

I did not have EFS backup so I used SRS unlock client with UART cable to bring back the original IMEI, now my IMEI and S/N is correct but phone still wont register on network. Any ideas?

LeEco X800 Le 1 pro US SIM and IMEI lost

Hi.
I bricked my LeEco X800 Le 1 pro and when I recovered it doesn't recognizes sim and the IMEI number is 012345678901234.
The radio in Phone info is off and I cant turn it on.
Preferred network type can not be changed.
I tried to use QPST to change IMEI, but it does not connects fully.
Tried rom vresions:
Le1PRO_US_X800-ROW-PB-v60-CUOCO92-5.5.014S.zip
Le1PRO_US_X800-ROW-v48RL-CUOCO92-5.5.011S.zip
I used QFIL to unbrick my phone and then it had 8gb rom so i formatted phone.
Now everything is ok except IMEI and sim problem
Help!

I have the same problem. No imei. Phone does not detect Sim card.

There is already topic about this here http://forum.xda-developers.com/leeco-le1-pro/how-to/imei-lost-imei-letv-1-pro-x800-brik-t3430035
We need a QCN backup from working phone to solve this.

Please Try my QCN file from my working phone.
I used Qfil for backup.

The user "mariocolino" from Forum.le.com has confirmed that this QCN backup has fixed the signal problem.
I hope it will help other X800_us owner with the same problem to repair their phones.
Some helpful tools & files.

This worked for me to enter diagnostic mode.

I flash QCN, imei appeared but there is still no signal and no sound, what can i try.

Use this brush tool. => https://1drv.ms/u/s!AidiAJYxvGs2cPhtLogbcsqjYEo
It will get back all system defaults.
BUT WARNING!
It has a malware that installs apps itself.
After brush tool install custom ROM like cuoco92

if 4G doesnt work, try flashing the Non-HLOS from an x800 US image
Yoy can also see if you can activate the bands on the QCN file with QSPT

Lost IMEI and Baseband version - NO REGISTRY ON NETWORK - PLEASE HELP - SM-A550F

Hello everyone!
I was flashing a custom rom and I realised that my sim card is not detected...
I tought that it was a problem with bootloader and modem so I flashed them and still, the sim wasn't recognised.
Then I went to the settings to check IMEI and baseband and it was unknown...
After many and many tries I still can't feagure out how to fix this...
I flashed it to a stock rom and the baseband is still unknown...
I changed the imei with xposed extension succesfully but the sim still doesn't work because of baseband.
Please help me... *I was stupid for not making a backup*
My phone: SM-A520F

You made sure you flashed the right modem and bootloader for your model/carrier as different ones have different bandwidths.
Sent from my SM-A520W using XDA Labs

i had the same issue , you need to flash the same firmware that came with your device but all of it ap cp csc also for bootloader use one more recent because it isnt allowed to downgrade , (for example my phone had the xeo csc and flash cos to make 4g lte working in another country and carrier but lost imei and sim , to fix it i had to flash the second XEO firmware found on sammobile witch was the one the phone had when i bought it
