Hello, I was installing a rom xiaomi.eu to my new mi4c as it came with a ROM 77 loaded with a lot of bloatware.The phone bricked while installing it and couldn't even start in fastboot mode. Luckily with a tutorial I could recover. The problem is that the IMEI got erased. And the phone had no signal and couldn't detect SIM.
I a tutorial in order to repair it with the QUALCOMM QPST TOOL the problem comes when trying to read the xiaomi with the RF Manager NV only has 4 NV files, not even the IMEI or anything.
Creating IMEI I could get the phone to read SIM, and to show IMEI when typing *#06#. But no signal.
Therefore the only solution I can think of and that saves my phone is that if someone is kind enough to make a .qcn backup of his Mi4c and share with me to restore my Mi4c (obviously would put my IMEI to it so no worries) so the phone can work normally again with signal and so...Thanks a lot, I need your help.
Hey I really appreciate any help that you can provide. I will tell the long story. My phone got corrupted while flashing different custom ROMs. Oxygen was the culprit. It completely damaged all the partition of my phone. So I repaired via 9008 modem loader using COLOR OS flash tool. then I found there is no baseband and IMEI. EFS partition damaged and I didnt have a backup. Damn it!!!!! Tons of research and googling I found how to use QPST tool by Qualcomm. I retrieved QCN file from friends ONEPLUS ONE (16gigs) and flashed it to my phone (64gigs) and edited the IMEI to my one. Rebooted the phone. tada. I got wifi bluetooth everything running. Phone signal just connects and drops every sec. It wont stay connected. but it is detected. then I thought it might modem issue. I tried every single modem out there but no luck. Finally flashed CM11s 44S Modem. Kaboom. Got the network running. but sadly it will only connect to 3g. I cant connect to 4g. No Other modem works.
1. Only get 3g service via 44s modem on any vanilla rom.
2. No other modem works.
3. Proximity sensor acts really weird. If a call comes Then I have to restart my phone to get the screen lit back. Fixed by flashing proximity fix
4. Baseband is always unknown with 44s Modem but has 3g network connectivity.
5. Other modem shows baseband but no connection even though it is detected.
Please help me guys.. What am I missing. any help appreciated.

1- Check If you have IMEI and IMEI sv and it's the IMEI that shows on box.
2- if no. 1 is true then check another sim card another operator ( to be sure that carrier is not blocking your IMEI for some reason).
3- if other operator's sim worked contact your carrier to check problem with them.

Hey thanks for the reply. I do have my IMEI from the box. I flashed QCN file using QPST tool and applied my IMEI but the thing is I only get 3g. 4G is not detected. Im not sure if something has to do with baseband files. But my friend is from my place and he gets 4g just not me. If I use any other modem other than 44s Modem the network will be detected but won't connect so i cant make or receive calls or anything related to service provide.. Do you know what to do ?

Okay let's make some tweaks :
1- backup modemst1 and modemst2 using dd (I don't trust qcn backup ) and copy them to your computer I also prefer to backup persist and fsg
2- download NEVER_SETTLE from https://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061 (you will find commands to backup mdemst1 and modemst2)
3- flash only persist using fastboot and reboot to system and check everything again.
other partitions locations :
/dev/block/mmcblk0p18 (fsg)
/dev/block/mmcblk0p15 (persist)

IDK what i did my opo was dead for around 3 months, the screen was responsive but totally black. then managed to recover from it then bricked it.
just figured it out. I am on my own build of XOSP[maybe it had problem idk] but had to flash my efs[64gig] backups and got my original imei back [earlier i had restored to a different imei qcn file may be it belonged to a 16gig opo] and also got 4g signal but still no baseband.
Then flashed COS13.1.2 and got baseband back, now the proximity is also working as it should and also got LTE working and instant signal on restarting the device. Now again back on XOSP everything works. If you need i can pm the efs files.

FYI your IMEI will be lost if you do so.
So I suggest to backup your partitions first in case of everything goes wrong.
Any way I have qualcomm stock efs partitions with 0 IMEI in case if you need them

IMEI is encrypted so if you do so, you will see it in settings but network carrier will receive it 0. This means that you won't get 4g also only 3g. So I personally prefer that you flash efs of [MENTION=bablu084;70545585]bablu084[/MENTION] this gonna work except you're two in the same country.

anyone can help provide me a working D838 QCN ?
i was accidently changing the 3G bands. but it cant be reverted.
if any one can give me your qcn backup ( you may delete your esn /imei value, i dont need it) i just need the network config inside the qcn.
i will give $10 via paypal to anyone who would help me for this.
i've restored my imei and esn succesfully, but i only get 4G full bar and 3G on some spot... compared to another phone, i should have a 3G signal on where i should be. but i cant connect/register to it. it says, current network is disabled.
anyone have an idea ?
LG D838 QCN file needed
Please I have issues with mine too (LG D838 32g). When I put it to 3g/4g mode, I get no network reception at all but when I switch to 2g, I get reception....please I need the QCN file if you were able to get it or point me in the right direction. Thanks
