Hey guys i am facing network stability issues on my canvas a1 on stock rom version MMB29V
In order to check if the sim is faulty i used it in an infocus phone and did'nt face any network stability issues.
Can someone help me out with the problem?
did you recently flashed or updated your firmware. its common with mtk devices that your imie gets lost after flashing all you need to do is check if your imie numbers is still in your device to do that go to settings-about phone-status(phone number,signal,ext) and check the imie number if you cant find any then you gotta manually install your imie number
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

Dont update the imei was changed becuz it was most likely black listed aka phone has been reported lost or stolen
Hi,
I have a redmi note 5 AI/Global which I've had problems with - it's unable to get a signal with the sim card. It lost the imei numbers (and I'm assuming Baseband) with a TWRP restore where the user tried restoring the efs/modem partitions. The phone does pick up the network, but it doesn't show any reception. The sim card works fine in another phone.
I have:
1. flashed the baseband using the model's qcn using QPST
2. Changed the imei back to default using the imei change tool
It's currently on the latest dev rom. I'd really appreciate some help with it
try to search for qcn for the same model and restore it on your phone, it will work for sure
I've been looking for it, unfortunately I haven't been able to find it - it's M1803E7SG
because your modem file corrupt ,try this method may be can help you... i try this at other phone is work !!
https://www.theandroidsoul.com/fix-...d-wifibluetooth-issues-restoring-twrp-backup/

Download the same fastboot Rom version and flash it via mi flasher, don't forget to choose flash all
