Need help fixing VoLTE - Xiaomi Mi A1 Questions & Answers

Hi so, I accidentally erased my entire eMMC chip while flashing firmware and lost my efs partition. I managed to restore it using a backup someone had posted here on XDA and then flashed my IMEI using a bunch of different qcn files, but all of those qcn files which were labeled as "for Mi A1" were for msm8952 chipset or msm8976 chipset both of which this phone doesn't have. Hence VoLTE no worky. So I decided to flash the EFS backup I found which had no IMEI and take a qcn backup and write my IMEI to that. But I don't know how to write my IMEI to that. So I'm gonna leave a qcn for the msm8953 chipset with no IMEI here hoping that someone can help me and someone else in need finds the file as well. PS: apologies if I posted this in the wrong category

LG G2 D801 Efs needed

Hello everyone. I signed up on this site and can be mistaken with the choice section. I need help. In my phone Efs deleted files and I need to restore them through Twrp recovery. Please share these files. This is very important.

Don't think anyone will share their efs files but if you Google you can find the qcn files for the D801 and use qpst or efs professional to load

He came to me in fastboot mode. I flashed him partitions then flashed through his native Flash tool from the D801 firmware but now he loses network coverage and is not determined by z3x box. One man suggested to restore EFS files through TWRP recovery and restore your phone via z3x or Octopus box
ESF professional can not detect the phone and Qualcomm NV Tool also can not connect to the phone. It is great flashing through Flash Tool. How to recover EFS I have no idea.
You're going to have to search xda. One guy did a full write-up on how to use qpst to fix your problem.
Getting all the files needed for qpst to work will allow efs professional to detect your phone. Find histhread and you'll be able to fix your phone

lost IMEI, please help!

Model NO:- GT-I9500, INDIA BLACK EDITION
without any knowledge of efs i just downgraded from 5.0.1 to 4.4.2, and i lost my IMEI.
my IMEI is shown as null. I searched a lot, and found that there is some problem with EFS, but could not find a solution.
I've tried flashing some modems, and I'm also currently downloading the 5.0.1 firmware and will try and flash it.
now is there any solution to get my IMEI back without any EFS backup, and preferably without root?
I managed to get a 'efs.tar.gz' file from somewhere, but i dont know how to insert my IMEI into it, and flash it via odin?
any detailed solution please?
sorry if there are any existing threads about this..
Reinstall the 5.0.1 firmware. Your IMEI should then be restored.

Wrong forum..
Install a factory test rom, backup efs, install whatever rom you want to install and restore efs if it doesn't work already.

Restore backup then flash official stock firmware using odin.without factory rest or hard rest.
If its same no changes.get new imei using online remote service.search on Ebay or imeiguru website.

NVRAM and NVDATA Files

Good day guys,
I recently bricked my Zenfone 3 Max, ASUS_X008DA (MT6737T) trying to boot a corrupted image.
It's now however, up and running after 2 whole days of searching the correct firmware and flash with SP Flashtool, now it has been upgraded to Android 7.0 N as well. I wanted to root it again.
BUT, I noticed that my IMEI is NULL!
I tried Maui Meta, SN Write tools to no avail.
I also have an MT6737M scatter file, NVRAM and NVDATA file which I download from my local forum.
Question is, can I use the NVRAM and NVDATA file (I'll modify the scatter file on my stock rom). Or does anybody have other ideas for this?
Once again, I have tried all suggestion but to no avail, excuse my English since it's not my first language, any help will be appreciated.
Thanks anyway!

Help with a twrp backup

Can work a custom too no problem .
Someone please?
i can help you with modem backup, but i can't send you EFS bsc of my IMEI
@twistergear
It will work, but, both phones will have the same IMEI #. That's the reason why no one will share their efs folder (files).
The best way for you guys is to send your phones to the service centers, so they can restore your own original imei numbers.
