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

(You can open the QCN with 7z)
compare the one that is working with other that have 2IMEI and see the differance and try to edit with a hex editor, if you can't then your best bet is 4pda

What board version do u have ? I lost my imei too when unbricking with Test point via edl
I couldn't restore my imei can u tell me your Telegram so I can ask you some questions tjnx

Try searching for these terms on google. "deadboot repair" "edl" "firehose". Usually after flashing a deadboot repair package the imei resets by reading the chipset. Goodluck.

To my knowledge the imei value is stored/burned in the soc on all snapdragon chips. I am not sure why it did not auto regenerate after an edl flash.
