Imei is "0" / nv backup partition invalid / engineer mode - Oppo Find 7 and 7a

Hallo,
I have tried to flash a new ROM on my Oppo Find 7a. Everything is doing fine, but now there is a message that the NV BACKUP PARTITION is invalid and my phone can´t connect to my phone provider. I think thats beacuse the IMEI is "0" now. Unfortunately I don´t have backups of the NV Partition.
I have found some keys for acessing the engineer mode for the oppo find 7a. Is it possible to restore the IMEI in the engineer mode? There is a menu called "check and encrypt IMEI".
Another menu in engineer mode is "Privilege". But I can´t acess it because it prompts for a password.
Any ideas what to do now? Is there a solution or do I have to send my phone to OPPO? I think OPPO can write the IMEI back?
Happy to hear from you.
Greetings Markus S.
My english is very worse but I have tried my very best and I hope you can understand what I have written.

[Q] No network Service / No Serial / IMEI OK

Hi!
Problems:
1) Serial is 000000000000000, although IMEI and IMEI/SV is ok.
2) Out of service network state, although network is detectable.
Solution:
Ariza Patch.
I know I've given the solution, but everytime I have to reinstall a ROM I have to do this over and over again which bothers me, besides having a serial number is better than 000000000.
The thing that caused this was a google app named swapper. I believe it stored the swap file on the partition of the EFS.
The phone's EFS was fixed by some technician, but unfortunately the serial was not.
No, I do not have a backup of EFS to restore. I only figured that out after this happened.
Other apps used to diagnose:
Check FUS - it says on "Product Code" as "Not Active"
CSC Select - played with a bunch of CSC codes to change, still no luck.
Galaxsim - shows my real serial number but phone is already unlocked.
Any suggestions would really be helpful aside from sending it back to Samsung Service Center and restoring a backed up EFS which I apparently don't have.
Thank you!
Ive this problem too

[Q] Cannot switch from factory mode to user mode - efs partition problem

I have a Samsung Galaxy Tab 3 T311, also known as 8.0 version of Tab 3.
I had accidentally corrupted my efs partition, and my tab got into factory mode which I hadsuccessfully disabled by using terminal emulator commands which change the text OFF to ON in ffactorymode and keystr files. My IMEI had also been changed, for which I gave it to service centre and they fixed it, and the factory mode came back which they were unable to solve. Once again i rooted my tab and tried to run the command, but it didnt work. I also tried to manually change the text, but to no avail. Tried to see into some of the other files, but couldnt find anything that might be wrong, but I found that the text in my serial_no was 00000000000. Unfortunately, I dont have a backup of my original efs, so I cant go out the easy way.
It would be a great favour if anyone could help me out here.

Lenovo A806 Rom

Hello i tried experimenting with some custom roms and now my sim card is not being read at all.
I first installed this rom: http://www.needrom.com/download/lenovo-a806-multi-lang-1501_7-80-1_dev/
And everything worked correctly except that sometimes certain applications crash.
After i decided to try out another rom: http://www.needrom.com/download/lenovo-a806-miui-v6-13-language/
The second rom was working correctly but there was one problem.. The sim card was not being read.
After i had this problem i decided to go back and install the first working rom (the A806 multi lang rom) but the sim card issue still remained.
Please Help !
P.s My phone is Lenovo A806 and i reside in europe. I tried searching for the stock rom of this phone but i cannot find the stock emea rom whcih works in europe.
When you flashed one of the ROMs, your NVRam was deleted or destroyed.
You can fix this with nvram tools. Just the IMEI is missing. After entering the IMEI everything is fine again.

Hi, I just read about NVram took and it only restores backed up IMEI numbers. I did not do a backup. My problem is listed below. Please help.
I bought a new Lenovo A806 (version android 4.4.2 - build VIBEUI_1432_ST_A806).
There were lots of Chinese writings imbedded in the rom and apps so I rooted the phone and tried to disable some apps and stupidly removed the stock phone dialer and contacts. Then whatever replacement app I tried from the Google play store did not work.
The replacement dialer gives me the message:- “You have removed/disabled Stock phone application, its required to properly functionality.” (pardon the Chinese English)
The phone cannot read the sim card and the IMEI number has disappeared. Following forum advice, I installed “mobileuncle” but cannot insert the IMEI number manually. When I go to Engineer mode, CDS information and try to go into Radio information, I get the message - “Unfortunately, Common Data Service has stopped.” So I cannot even go into Radio information.
I researched on the internet and tried to change the Rom. I installed the required version of TWRP recovery and after trying a few Roms, I managed to get Version VIBEUI_V2.0_1508_7.85.1_ST_A806 installed.
This version behaves better but still no IMEI number. Instead I get a different message – IMEI invalid.
When I try to call, I get this message: - “To place a call, first turn off Airplane mode”
But Airplane mode is off. But at least the dialer seems to be working and I am able to add contacts.
And I can get to radio information from mobileuncle with this version but when I type the IMEI number after the ST.., I get the message: “This command is not allowed in userbuild”
Even with a space between the ST and +, it still does not work and I get a different message, “at command is failed to send” I even rebooted after inserting the IMEI number and still no joy.
However, the wifi seems to be working on both above version and this.
I have a backup of the original corrupted rom so if anyone has a solution for either one, please help.
I installed the rom’s through TWRP recovery which is on my phone. I press volume and on/off buttons to enter into this.
I tried the NVram
Hey, I had the same issue a while back, it's actually easy.
Get imei.exe
Save it to this path: Windows C/Users/HP*
then open cmd, windows+R then type cmd
Type imei.exe followed by the imei
It'll generate a file, mpob format
Cut it from the path you pasted imei.exe
Paste it on your phone.
Get a file explorer that can access the root of the phone after granting root access.
Once you can access /device, go to this path /device/data/nvram/md5/Nvram_Imei
Then paste the mpob file there. If there's an existing one, delete it and rename the one you pasted as MPOB_001. You should only have one MPOB file there.
Now reboot.

*ISSUE* How to restore IMEI (SM-G532G) Galaxy J2 Prime

Hi. I tried to change my IMEI number using the Chamelephon app. It did work, but it didn't turn out great. Network functions are okay, but it needs constant network operator scan as soon as I turn on airplane mode or restart my phone. The IMEI number became random numbers and symbols.
IMEI 1: >8<4=<:7?7<6?:2
IMEI 2: 9><398?64><6086
EFS is fine. Only IMEI has a defect.
I realized that Chamelephon should only be used on MTK (chinese or cloned) devices. Now I can't seem to find a way to get it back. Can someone teach me how, and do I need to get any Samsung Tool Pro type of things? If yes, how do I get started? (btw I want to do this for free)

[Xiaomi Mi 10T Lite (gauguin)] need help for firehose file patching

My mi11 bricked.The screen only shows errors: system ui isn't responding,I entered recovery mode and then upgraded to the latest system now.but nothing changed.I also restored the factory settings, but the problem has not been resolved.
Miflash error: Flashing is not allowed in Bootloader Lock State​so,i need help for the firehose file patched to skip the EDL authentication for flash rom (gauguin_images_V13.0.11.0.SJSEUXM)
Many thanks for your help .
It will be you are hard to find. Weather try in developer options to unlock bootloader wait 7 days and flash again
its bricked.Unable to enter settings, unable to open developer options
I bought a second-hand mobile phone to restore, because the display was broken, the seller said that there were no associated accounts, as the display did not show an image and only sound, I deduced that everything was going well, when I tried I found that I had an MI account associated. the seller don't know also the mi account information, now I can't use it at all, I didn't want to spend more money on the phone so I tried everything that is within reach on the internet. The mobile has:
1. My account (I don't have the information)
2. Impossible to unlock the bootloader (I can't access the mobile phone)
3. Impossible to enable debug mode (I can't access the mobile phone)
4. I can connect in fastbook
5. I can connect in adb sideload
6. I can connect in EDL mode (Qualcomm 9008)
I tried QPST, QFIL, but it always gives an error, maybe because of the firehose.
As the bootloader is blocked, I have no more chances for free, the last hope was to try Firehose in Auth for this model, but I can't find it anywhere.
The cell phone does not detect the Touch, and every time I turn it off it restarts automatically. However I can use a mouse in OTG.
I thought if I did a flash it would solve it too.
The last solution is to pay someone who can do the job and guarantee that it will work without restrictions, for that you would also have to find someone you can trust.
