Hi! I finally booted my Redmi 7A. But now, the IMEIs are missing. I tried a QCN file online, but it made the phone stuck on Recovery mode with the "NV Data is Corrupted" notice. Fixed it by wiping the modemst1 and modemst2 through TWRP.
Does anyone have the QCN file for the Redmi 7A? And how-to's to fix the missing IMEIs? Model Number is M1903C3ET.
Thanks!!!
do you get any fix. I am facing same issue

Hi! I have already downloaded the qcn file you've attached. However, on Miracle 2.82, Redmi 7A is a not listed model. Can you please provide more instructions? Thank you!

Thank you! It has worked! The phone happily accepted the sim card. However, LTE doesn't work. It is only fixed on EDGE. Is that the same case with you?

UPDATE: Sorry, we tested it outside of our home and LTE works properly. Thank you so much!!!

After flashing multiple roms & testing, my IMEI is ZERO! Even after I inject new IMEI which I copied from back of battery compartment, I still could not get any network connection (emergency calls only).
If you own the same model & region as mine (ZE550KL z00ld ww), please donate your working QCN to me! I have troubleshoot this issue for the past 48 hours without any improvement, a search yields many phone owners with the same problem. Some cannot get 3G/4G anymore and are stuck on EDGE/2G. My country's 2G infrastructure will be taken down in 3 months time.
This problem could be due to ROM flashing, OTA upgrades, selecting RADIO BAND to USA when living in another country, deleting the modemst1/st2 files etc etc
You may want to replace your IMEI with some arbitary numbers 1199119911991199 or something, even if you don't input any numbers, I will use my own IMEI. IMEI is stored at NVram item 550, just exclude it from the file.
For reference, links to do the change IMEI and restore successfully,

Edit: I just did a Network Reset, now my WIFI cannot connect, bummer, wth!
bump, help please!
why can't anyone from this forum try to help me???? (devs included)
u just have to put the phone in DIAG mode (adb shell -> su -> setprop sys.usb.config diag,adb), any CM13 rom will do
install qualcomm drivers
launch qpst
make a QCN BACKUP file
then use a hex editor to edit your IMEIs to 111111111111111111 and attach the files here
that's it, the file is around 700kb only
i find it hard to believe no one else except me need this file.
If u are an avid custom rom flasher, u need this file too!!!! coz its simply too easy! to bork values in the nvram, just by flashing nightlies, ota updates or just trying a new rom, and there are many roms to try here
btw: I found 2 copies of RAW/SERVICE ROM firmware for ZE550KL, it's vital to revive any hard bricks due to partition failure of any kind, will post links later after I find the original links again
Asus Zenfone 2 Laser ZE550KL (Z00LD, WW) SERVICE ROM or FIRMWARE
Service rom/firmware is vital to recovery from any type of partition failure, it is flashed using Asus Flash Tool (AFT). Note that this is different from the usual Asus ROM upgrades. If AFT fails for whatever reason, simply unzip the file and run flashall_AFT.cmd, it's a simple batch file.
there are 2 files, one from a russian forum, another (can't remember), I lost both links but will upload my copy using a higher speed link, mine is 4Mb broadband package only, upload 512kb max.
filename : WW_ZE550KL_21.40.1220.1794_rel_user-20160722041335-secured-releaseAFT.zip
filename : [firmware27].WW_ZE550KL_1.17.40.1234-rel-user-20160304185904-secured-releaseAFT_QC.zip
note: this forum is hopeless!
did u flash the modem, i don't have much knowledge, but i got networks after the modem flashing
nothing worked except a working qcn file (ze550kl), heck i even tried flashing qcn from lenovo/xiaomi which has the same snapdragon chipset, didn't work, radio is dead.
pls make a qcn file, then replace your imei with some other number (111111111111111111) & attach it here, it's for the benefit of others as well.
thank you.
How To Fix Unknown Baseband In Qualcomm Based Phones.
Today 8 out of 10 device by Qualcomm in market and there is one common problem in Qualcomm based phones which is Unknown BaseBand.
Some try to flash phone and some write modems or radio but mostly have no idea why baseband got unknown.
I'm not here just giving solution for Baseband i will tell you reason of this too so you can easily fix whenever you will get device for same.
Reason of unknown baseband & Solution :~
Wrong firmware flashed on device - after flash wrong firmware there is chance to lost baseband because maybe the older firmware look for baseband in c drive (just an example, the author meant 'looking for baseband in the wrong location') and your flashed firmware search it in d drive so you will get unknown baseband cause of wrong path of EFS in firmware, so you can easily fix it by flashing (meaning stock rom)
Corrupted EFS so to fix corrupted EFS you have to erase EFS partition which is MODEMST1, MODEMST2, FSG, please backup these partition first before erase or just erase MODEMST1 and MODEMST2 its safe as FSG is golden copy for them. (FSG is actually a backup of MODEMST1 & 2, golden copy meaning if phone detects erased/zeroed modemst1/2, it will auto copy FSG to modemst1/2)
You can erase partition in fastboot like this "fastboot erase modemst1" and same for other just change partition name,this partition can be erase by adb too as boxes (professional repair kits) do but you will need root and some advance skills
Some time EFS not corrupted, its erased so you can not fixed it by point (2) so you need a working QCN from other working phone (same model) to restore EFS partition.
In order to read and write qcn you need 1 tools QPST ,there is lots of tutorials on net how to read qcn so i will not gonna tell you here same thing so i will cover only important part.
To read write qcn you need qualcomm DIAG port to be enabled and its depend on phone, some phone can enable this just by code and some need root, after root you can use my tool rbsoft mobile tool to enable diag port.
(For enabling DIAG port on ZE550KL, just go adb shell -> su -> setprop sys.usb.config diag,adb Need to disable Windows driver signing first, install Qualcomm drivers to work )
Now you can read and write qcn and you will get your baseband and imei back
To make your work easy i attached QCN in my post for latest phone which come daily on every shop now day.
keep in mind all qcn imei i removed and now its 35000000 (false IMEI) so edit & input your imei with hex editor.
Please if you have QCN which not in our list please post it here it will be helpful for others

Note that the DIAG port cannot be enabled if the phone is using stock rom, so flash CM13 roms so you can enable DIAG port via adb.

i am afraid that i cannot help you with the unlocking bootloader, there is no way to re unlock it, with 8916 there is a beta rom which has a bug in its fastboot which allows you to flash twrp without even unlocking bootloader .but i m afraid there is no such rom for 8939.But you can try and find one,just like i found the beta rom after a month

i used this to restore my mi a1. only flash /persist image.
if your persist partition is corrupted
than you will notice that your phone will automatically reboots in under 60 seconds
To restore persist partition download persist.img
fastboot boot to twrp
and copy persist.img file to root of phone storage
now open terminal in twrp and give the following command
dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27
this will restore your persist partition and fixes the issue of reboot
but be careful if u are a newbie, best option is just go to mi service center & let them restore ur phone.

yeah, and you are not rooting your phone just temporarily booting in twrp.
Everyone who installed RR is having the same problem i guess, normally custom roms don't touch persist and use their own mac.
also did you make a backup before flashing any custom rom. If you did then just flash persist.img from there.

bro just tell me one thin after doing that can i reflash stoc rom with mi flash tool as normal and everything will be fine or not, can i use my mi a1 as non rooted phone or not... please replay me bro
I had the same problem as you and i fixed it properly only by flashing again stock rom through Mi flash
Run Mi flash as administrator and flash all and lock
This will erase everything in your phone, so backup your files before.
This worked just fine for me now i have normal mac address for WiFi and Bluetooth hope it will work for you too.
thanks the developers whose are giving me some time for my problem

i used this to restore my mi a1. only flash /persist image.
if your persist partition is corrupted
than you will notice that your phone will automatically reboots in under 60 seconds
To restore persist partition download persist.img
fastboot boot to twrp
and copy persist.img file to root of phone storage
now open terminal in twrp and give the following command
dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27
this will restore your persist partition and fixes the issue of reboot
but be careful if u are a newbie, best option is just go to mi service center & let them restore ur phone.

u need to flash persist only if it's corrupted means if your phone is rebooting under 60sec and WiFi doesn't connect.
first tell me what was the problem and what steps u followed exactly.
for edl mode #
fastboot oem unlock
fastboot oem edl
cmd gives that error sometimes but phone still goes into edl mode your phone will power off but notification light will be blinking.

Hello, you fixed the problem? i lost the imeis but restore it with a QCN Backup, but i dont have signal... thanks for your help
i find the fix: thanks to tommyb2 in Lenovo english forum for the tip
As it looks like you damaged your qcn you need a new one !
is your WiFi working ??
if not try this first !
enter Fastboot
then
Fastboot erase persist
Fastboot flash persist persist.img
(your WiFi should be back)
try
Fastboot erase Modem
then
Fastboot flash Modem non-hlos.img
After that Fastboot reboot !
maybe also your imei ?!
if not get a QCN, enter Diag mode (see page 12-13)
and replace it with a new one !
with an imei editor you can put in your imei
The Files you found in your current ROM !
Non-hlos.bin has to be renamed to.img

Hello, I also deleted imei info by mistake, can you provide with a dummy lenovo z6 pro QCN file, so I can restore mine? Thank you
Is all lost?
It's been a few days and no replays, let me guess I can trow the phone away ? since there is no QCN file available for restoring
Don't throw away. Get a sain QCN file, put your emei in it and flash back.

I leave you mine with a random imei, change it to yours and tell me if works (change the extension to QCN)
something happened
Thank you for the qcn file, it did help but not nearly enough.
Any other ideas on how to fix this ? I'm giving up on this 'cuz it seems so ...... chinese .
Edit1: Do I need to change MEID or any other unique ids ?

mied, is part of the imei... not neccesary to modify...
now, do this:
enter Fastboot
then
Fastboot erase persist
Fastboot flash persist persist.img
Fastboot erase Modem
Fastboot flash Modem non-hlos.img
Fastboot reboot
I'm sorry it took so long to respond but I was on a trip.
It works, I've got my signal back, but sometimes when I start a conversation the other person hears bad, like when you speak underwater. It doesn't happen when I put my headphones(not yet anyway),
but I guess this will be solved in the future updates.
Thank you very much :victory: :good:

Doing "fastboot erase persist

Signal Lost
Hello,
No, I don't, the only QCN file I have is the one you gave me and modified with my IMEI.
As a note that QCN file give a warning that my model no. doesn't match when restoring, but it works on stock ROW rom.
Thank you,

Hi, if you are on ROW, update through OTA to 11.0.350. Many Z6 owners have reported it fixed connexion issues. It might help you as well!

Hello,
Sometimes i can;t because phone is rooted, sometimes when i get OTA update I can't install because after i press "update" it resets to changelog.
Also when I try to update through .ZIP file it fails and I lose signal.
Zip file name : L78051_ROW_SECURE_USER_Q00745.01_P_ROW_11.0.284_ST_190810_TO_L78051_ROW_SECURE_USER_Q00745.01_P_ROW_11.0.325_ST_190918 (renamed to update.zip)
Thank you,
One way or another, you need to find a way to update your phone to latest ROW rom which is 11.0.350.
Try unrooting and flashing back stock recovery. Otherwise find a full rom file that can be flashed with fastboot.
My issue is not with the version. My issue is with qcn file for my signal.
Most likely I will need a new dummy QCN file from Lenovo z6 pro from latest ROW rom version, change the dummy imei to my imei and restore.
Most likely x-geo will have a good idea of what I must do, 'cuz last time he solved my signal issue. If you have Lenovo z6 pro with latest rom you can back up your QCN file set a dummy
imei and send it over and I'll try and/ restore my phone, that will be greatly appreciated.
Thank you,
Liste, updating to 11.0.350 solved communication issue of many users !!!
May be it resets proper QCN partition or whatever. Anyway there is no point in staying with earlier ROW version they are crap !

Did that many times brother but it is still stuck in bootloop. The problem is that i have damaged EFS Partition. Ihave tried installing ROM through TWRP and also through fastboot with miflash. When i enter in Mi recovery i get message of " NV data corrupted".

You need to fix the partitions i think (idk how, but try on TWRP, there is a option to fix partitions) or in last case with fastboot i think its possible

Download stock rom and upack to the C:
copy this files from adb to the rom https://cs5-2.4pda.to/16762384/05.png?bc48fd2c50cba18a8da8778c9cdc19a9
run flash_all.bat
DONT USE FLASH_ALL_LOCK.BAT IF YOU FLASHNING GLOBAL ROM ON K20, THATS BRICKED YOUR PHONE...
If non of the above works than you can try this: https://romprovider.com/2020/03/xiaomi-mi-9t-imei-repair/
I know that i used something very similar when rebuilding EFS on my old Mi A1 and it did work. Though i didnt try it on Mi 9T because i didnt need it yet.

Ok brother. Let me give it a try.
Hey Bro, don't worry at all! It's because of EFS Corruption and you have to clear the partition and then flash ROM again with fastboot!
Boot into TWRP recovery.
From TWRP’s main screen, select Advanced » then Terminal.
Type the following commands in terminal (one by one):
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
Reboot device.
go to TWRP, Flash ROM
