Just as in title, I need backup of nvram from doogee x5pro device. I flashed cyanogen beta rom with twrp, but then couldn't go to recovery to flash google apps. I flashed back stock rom by unlocking OEM, it formatted nvram partition which backup I didn't have. Now i have flashed cyanogenmod rom but no imei. Tried to restore by android apps, engineer mode and sn write station etc. I just read i can change it by flashing backup and just write my own imei instead of imei in backup. I did one more bad thing, I used some guy imei.exe tool which broke my imei completely. Before my phone read sim cards but I couldn't call, send sms etc. Now it removed my baseband number I think. So... I just need nvram.bin from doogee x5pro to try rewrite it back with MTK droid tools.
Refresh, I'm just waiting for this nvram here and dying cuz can't use my phone.
Maybe too late, but for people searching for a solution.
If your baseband is OK, you can write your imei just typing on dialer *#8688#* It saved my ass
In case you have a totally corrupted nvram, try to restore this one with twrp.

After that, change the imei to your own (mine is fake)

Hi, after flash a rom, my mi3 doesn't detect baseband and my imei invalid. I tried to flash miui using fastboot (clear cache, data, everything using MI Recovery. Flashed dev global, stable and local roms) but still not fixed. I also tried using QPST but the memory dump is too small so I stopped. Anyone knows how to fix this? Thanks
Do you have a backup ROM using CWM? Because I had this problem before but it was fixed by restoring my previous CWM back up.
Have you seen the thread on MIUI.com about fixing IMEI on Mi3?

Ty for reply. I have done that many times but it seems that my nvram is corrupted. I dont know how but all the settings and configurations are empty including imei number. I flashed more than 10 times stock rom with different method and my baseband is back. Still the imei is missing. Then, I try to fix the imei by looking at the nvram memory dump. I injected my old imei (from mi3 service card) then the imei is back. Somehow, still no services.
I think that my nvram is badly corrupted due to random error in flashing. This is my first time having this issue because other phone (Sony Xperia) i have can easily fixed by flashing the stock rom. If only I have the hex file to compare. By the way, the memory dump is about 150kb. Too small isn't it?
Hmmm. . . . . Seems you need a really hard flash on that. You'll need to go to a service center for that.
try wiping cache data and then flash rom.
Hello everybody!
After restoring with TWRP a backup of MIUI by xiaomi.eu 8.1.3.0 (MAACNDI) stable, the phone shows baseband version unknown and No SIM card message, though the SIM works perfectly fine in other phones. Also, when dialing *#06# it shows correct MEID and both IMEIs, while in settings > about phone > Status > IMEI information it shows the right MEID and IMEIs, but it shows Unknown under IMEI SV (Slot1) and IMEI SV (Slot2).
I've already tried restoring older back-ups, fastboot flashing to global rom, wiping dalvik and cache, multiple reboots. I've run out of ideas. Any ideas about how to get the baseband and the GSM function back?
Also I don't have a back-up phone and I am kind of desperate. Please Help! Thanks!
You didn't back up efs partition with twrp? You should try this thread http://forum.xda-developers.com/mi-5/how-to/xiaomi-mi5-efs-backup-restore-methods-t3432730/page8
I have a TWRP backup of the efs, but after restoring it, there is no change. Actually I think the backup is corupted and it is the culprit that broke my phone, cause when I restored the backup I accidentaly restored the efs too and after that the sim isn't recognized. I tried following the above tutorial, but I'm facing a problem with QPST cause I cannot restore the modified qcn file. It gives me the following error "Received an invalid command from the phone" and the status "Memory Restore Failed!". I don't know what to try next...
For those having the same problem after an efs restore in TWRP this is THE SOLUTION:

THANKS for your answer!
With which version of twrp did you back up efs partition?
The problem was generated by a bug of the TWRP recovery (seems the 3.0.2.0 version, which I used for backup and restore was the one with problems). I think the bug was fixed in later versions, so you should use the latest version to avoid the problem.
My phone is working flawlessly again.
Details about the bug that causes the problem can be found here: http://forum.xda-developers.com/showpost.php?p=68500121&postcount=64
Cheers!
Ok Thanks i already installed last twrp and back up efs, i just wanted to be sure about this as i didn't want to go all through this process if i have any trouble

thanks, it helped to me too
First off - Mods, I have the original box and sticker IMEIs if needed as proof.
I have been flashing between AOSP and Stock trying to fix a Microphone bug on my phone (see previous posts), when all of a sudden my phone will no longer connect to Network (IMEI unavailable error)
I went through every QCN backup + editing I could think of, even using my friends Mi 9 that we both bought from the same place in China as a QCN backup + my IMEI edits.
Everytime I edit the QCN and load it, the phone just boot loops immediately shutting down upon OS load. Using MiFlash back to stock didn't work, and I had to flash Evo X rom to get it to boot normally now, but I"m also missing WiFI MAC onto of my IMEIs.
I seriously have no idea what to do. I've tried every IMEI editing tool or Hex Editor in the book to put my original IMEIs back in to no avail. What am I doing wrong that cases it to restart loop when I push my updated QCN file?
Thanks in advance - Can provide whatever else you need.

As i understand you have China version of Mi 9, saying: "MiFlash back to stock didn't work" you meаn you have flashed official xiaomi china FASTBOOT ROM and it did't work?
Then i afraid the problem is deeper then in the ROM. Because by flashing stock fastboot ROM you flash everything that possible to flash, ROM and all images, with all setting like it was from the store.

Correct. Reflashing China ROM in Fastboot does not fix the problem. It fixes the bootlooping but not the IMEI issue.
Hello. My redmi 9 was bricked so i used SP flash tool to repair IT. I used Download Only but my imei was gone. I used Eng rom and Modem META to restore IT. But when i restored two imeis phone was restarting on miui logo and miui recovery was showing
NV DATA is corrupted. So i reflashed Eng rom and using modem META i only wrote imei 2. Phone was working normally but my Wifi signal was very bad and my phone waz barely connecting to LTE/3G. I can make calls and send sms. Someone know what happened? I had nvram nvdata and imei backup on my sd card but IT got broken and i had to format IT. Please help this is very annoying and sorry for bad english.
I can't find any solution on internet.
I lost my baseband and IMEI after flashing Redmi Note 11R from China Stable to EEA Stable, so I follow guides on Internet and tried to reflash it with SP Flash Tool. I use "Format All+Download" but after that, I can't boot into system but always fall into MIUI recovery 5.0 with "NV data is corrupted" message.
Then I tried to use ModemMETA, but when I press write button, I always got operation timeout error, so I think maybe those partition were damaged.
Will flashing a new image fix issues?
I can give you that files, but it won't help. If you delete nvram - than your phone will not call any more, how to fix that - only on service firmware, but when you upgrade it to miui, no phone calls. I have the same phone, same problem, and no solution. Maybe in some month

Thanks for your helping, now it can at least boot into MIUI, not recovery. But the problem is ModemMETA tool now stuck at "Connect to MD" with good nvram files. Does that means I can only use the tool with corrupted nv data? That's weird. Also, I still getting unknown baseband and IMEI with China ROM, what version and region was your MIUI when you backup those files?
I have India, but it won't help you. If you want to recover your phone, you need to flash ENG rom(Format + Download) to use Meta Modem, then write only second IMEI. I have ENG rom if you want https://disk.yandex.ru/d/HFA-nWmHW8x1Kw
But then when I come from ENG to Stock - my baseband lock, phone no detect simcard. If I flash another modem, phone see simcard on stock, but no calls. I think it's becouse of baseband from nvram, nvdata + md1img that can't be applied on new phone with out change of Imei in that files, Meta Modet can't change IMEI in that files, it can only work on empy nvram, nvdata but with that files my phone don't calls.
So you need to flash stock and use special soft life Unlocktool to repair IMEI, I will pay some guy to fix my problem becouse I don't have solution for that. I spen about week on that problem in Internet - there is no solutions yet for that mode, Redmi Note 11E, 11R, 10 5G (light).
