Redmi 7A NV Data is Corrupted - Redmi 7A Questions & Answers

Hi! I have finally successfully booted my Redmi 7A (bootloop was caused by the persist partition being corrupt), but found out that the IMEIs were missing. Downloaded a QCN file for the 7a online and used it to restore the IMEI. However, after flashing, phone booted into recovery mode and had the NV Data is Corrupt error and won't boot. How to fix this? Thanks!
Update: Was able to boot my phone now by wiping the modemst1 and modemst2 through TWRP. The only problems right now are the two IMEIs that are missing. And, I don't know what my IMEIs were and I don't have its box and no other sticker present on the back except for the Model Number. Please send help xD Thanks in advance!!!

you got any solution

(SOLVED) Zenfone 2 laser Z00LD (ZE550KL) (2GB RAM) (MSM8916) completely bricked

I request someone please upload the full emmc dump or post it here. my device has been bootloader locked so cant flash the fastboot userdata.img its stopped working. i need a emmc dump rescue.
thanks in advance.
Update:1
i have dumped whole emmc on other device ze550kl it has bootloader unlocked and rooted with supersu. the point is when i try to write the full image using EMMC RAW Tool it gives an error write failed at the end of it. Phone doesn't boot and it goes to quallcomm bootloader 9006 or fastboot mode. if i try the rescue files which on the other thread (https://forum.xda-developers.com/zenfone-2-laser/development/unbrick-guide-z00l-ze550kl-t3600527 ) phone boots to fastboot mode but i cannot access the recovery or it wont boot to recovery. this is what i have done several times when it boots to 9006 mode i have deleted all 29 partitions in minipartition tool then created only one ext4 partition as a primary then it goes to 9008 mode. almost i tried all suggestions from addy692 nothing really worked as expected. if you have some ideas regarding this issue let me know in this thread.
Update:2
i have unbricked Z00LD from the dead and Please download the folllowing file ZE550KL_MP_RunChange_0721_Ver136_8916_V001.zip and extract it to somewhere else then write all partitions using EMMC RAW tool
if you are facing write error leave them, some partitions may fail to write i don't know why please choose write selected partitions and uncheck some of the partitions if you facing write error,you have to do it manually by checking one by one and write them as well. when its done connect your phone to fastboot mode if its not working try unbrick files https://forum.xda-developers.com/zenfone-2-laser/development/unbrick-guide-z00l-ze550kl-t3600527 then flash the Raw Firmware which you downloaded earlier that's it. if you face imei null afterwards Restore the QCN backup with QPST.

EDIT: I just realized that there is only 600KL an not 550KL, that's a problem because I'm also looking for the 550KL, but maybe is compatible as the firmware is labeled Z00LD too. I'll update you if I find something.
Have you find any link ?
unfortunately nope. But my phone is back again working just doing some work from TWRP and leaving it bootlooping for an hour.

used TWRP to repair all partitions, flashed stock recovery, stock boot an stock rom, leaved it bootlooping for half an hour and he started.
Did you unlocked your bootloader before flashing twrp.
anyone figured out how to do repartition of ze550kl?

Help with m3 modem partition

After my m3 got stuck in edl I messed up my modem files ending in NV data error and unable to boot. I tried engineering rom to fix it but to no avail I still get NV data error on release rom. I'm asking for a twrp backup of modem partition for m3 or any suggestion on how to fix this.
PS edl bug is still present when my phone refuses to boot I leave it for a few days to drain then boot via fastboot.
PS I did find a strange hack to boot up the phone and that is to use engineering rom modem file, but then network does not work and also there is a strange looping effect when playing video files in any application inc vlc or Firefox.
