I have installed some custom roms, some of them messed with the NVRAM, and IMEI, I was able to restore IMEI and 4G data, but the Camera stopped focusing. It could have been a bad ROM or maybe the Flash All option on the SP flash tools, I dont know, I tried restoring stock roms, wiping and everything I could imagine, also different custom cameras apps, i just wont focus,
can someone please post their nvdata and nvram here so I can restore it and maybe that could ix it?
thanks!

First of all, i want to ask if this is a major problem. My device seems to work with no problems, for now.
Secondly, is there a way to revert back this change?
Thanks.
Flash a stock ROM to see if the imei returns to the original.
I tried many times to restore from backup without success. Then i tried to flash the stock rom (i wipe before and after) without success again. Then i gave up and tried restore my backup again.....and then success!!! I don't understand why...
Thanks for your help.
Also i couldn't find the latest "normal stock" rom LUX, i only find the Le fleur. i think the differences are visual only.
Hello everybody. I have a issue that is litterally making me go crazy. Basically, on every custom rom i've tried so far (Pixel experience both normal and plus, HavocOS, CRDROID, every one of them in their latest versions) video recording through any kind of camera app doesn't work, except for the ANXCamera_Unity_157, where the video recording works, in a very smooth way, but it has a bad video quality, looking like it has a very low bitrate. I unlbocked the bootloader while i was on miui 11.04 global, i wiped everything and formatted DATA through OrangeFox recovery, i'm saying this because i saw that nobody has wiped out the Internal Storage during a custom rom installation. Thanks in advance.
--UPATE--
I tried to flash the miui 10.3.10 through fastboot, and the camera didn't work at all at first, then it asked for permissions and started working, however i still can't record any videos, except for short videos. I tested the hardware and the hardware is okay. Before this i tried to restore a backup that i made on orangefox before any rom flash, and the backup doesn't work. I tried to flash the miui 11.04 global (the rom i had at the beginning of everything) from the recovery, and camera didn't work completely, along the wifi connection (i open the wifi, click on "activate" and it stalles, then turns itself off and makes the phone laggy) i don't completely know what to do, i've been searching for fixes for a bit now and it looks like i'm the only one on the entire world who has this issue. I do really need some help or at least an advice or something
--UPDATE (FINAL)--
While i was too concerned about the video recording i didn't notice that there wasn't a single sensor that was working, so i figured out that the persist partion was corrupted. I fixed everything, video recording included, just by flashing the stock MIUI (11.05) through Fastboot, and then, from the same .tgz file (the fastboot flashable rom, you can find that if you search on the internet), i took the persist.img and flashed it using orangefox recovery, and it's done, i fixed that.
hey, I'm asking you two things for help .. :crying:
So, this started when I wanted to change the custom ROM, before I used ROM Miroom, then I switched to ROM Mi Globe, I have followed all the procedures ..
After I changed to the latest version of Miglobe ROM, suddenly the sensor on my 9T Mi completely died, the gyroscope, the Proximility sensor all didn't work.
And the second problem is that the stabilizer on my 9t mi camera is not as smooth as the default stock ROM, I see the difference, on the custom ROM, the stabilizer on my camera when I record, there is almost no stabilizer effect on the camera..
now I use the stock ROM mi 9t global version 11.0.4, and it does not affect the two problems above .. I feel tired because I have not found the answer
is there any solution ? thank you
Your persist partition got corrupted. Did you do a backup before installing the custom ROM?
no, I never backup persist. every time i replace a different rom i don't experience this problem.
well atleast you know that next time you will.
You can try this: https://www.youtube.com/watch?v=omjoGI3VpPM&t=169s
Basically do a backup of persistbck partition and flash it to persist partition. Altho it my not work. If you expirience some bad behaviour than flash the original (broken) persist back and you will be where you started. If this dont fix your issue than you will have to flash persist.img from fastboot rom. You will lose L1 DRM permanently after doing so.
After smashing my head against the limits of the MIUI again, i decided to say goodbye to my warranty and flash a custom rom. Via TWRP I flashed the latest (stable) version of Arrow OS based on android 10Q. Everything works perfectly aside from the popup camera, that appears to be firmly locked in place feeding live feed from inside the chassis. Thinking it was an error of that release, i tried other ROMs, both Android 9 and 10, ResurrectionRemix, Lineage. With RR the problem is the same, while with Lineage, the camera asks for a calibration: it actually pops out fully does two or three pops and then it says calibration failed. The servos are working, I've opened the chassis and found no dust at all, so I've looked for a fix online. The most common one is a flash of the stock 'persist.img' image, I've tried several times via TWRP, tried a few clean flashes (ROM+image) of different versions and nothing. Am I missing something? I don't want to get back to MIUI...
Did u backup your persist partition before ? if no u can flash any other one that comes in the fastboot stock rom but u will loose L1 (netflix in HD)
The problem persists.

I did, but even when I tried flashing different versions of persist.img ranging from fastboot stock firmware 10 to 12, with and without backup, (clean wipe, fresh recovery) the problem was still present. I'm no expert but I'd guess the OS doesn't know how to: either tell the servos to pop the camera out (Arrow OS) or recognizing the camera working when calibrating (Lineage OS). I'm trying to dig my way to the cam app in the MIUI release and to install it in the custom ROM, but I don't think it works.
SOLVED!
First I apologize for the English, I'm using google translator.
Hi everyone, I really need help. Yesterday I used adb to reinstall the stock rom oreo 8.1 (XT1683 POTTER RETRO 8.1.0_OPS28.85) everything went well, until the cell phone started... After installing the rom, I realized that my 4G doesn't work anymore, only the network 3G. When I put on the LTE(4G) network, the network is without signal. I installed more than 4 custom roms in an attempt to restore the 4G signal, but none of them worked. Reading some things here on the forum, I saw that it may have corrupted something in the file system, but I didn't find any solution. My IMEI is normal, the only problem is the 4G network that doesn't work anymore. Anyone have a solution? I don't have any files backed up. I'm currently using the custom rom (dotOS-R-v5.1.1-potter-GAPPS-20210614-0527) and I still have the same problem.
Anyone have a solution? If there is a solution and it is on video, even better. But it can be in text too. thanks in advance
Edit: Now I'm totally out of signal, just Wifi. My IMEI is normal, but I don't have a SIM card signal.
Edit²:
Problem solved.
How did I solve the problem?
I kept installing and reinstalling several roms and nothing worked. So I decided to install the Nougat 7 flashable rom, that's when after installing I realized that the 4g network was re-established. I immediately restarted the phone in recovery mode, accessed TWRP and saved the EFS file to the memory card and a pendrive. I reinstalled the custom rom I wanted and the network stopped working again, I checked and the IMEI was 0 so I restored the EFS file that I had backed up on Nougat 7, and it worked perfectly in the custom rom.
But another problem appeared, the fingerprint did not work. So I reinstalled the custom rom and it didn't work, I reinstalled the Nougat 7 flashable and the fingerprint came back, but when I installed the custom rom again, the fringerprint was disabled again.
To solve the fingerprint issue, I installed the Oreo 8.1 Flashable Rom and then installed the custom rom and the fingerprint issue was resolved.
NOTE: My LTE/4G network was only re-established because my IMEI was not reset, for this reason I managed to save the EFS file and restore it to the custom rom. I don't know it will work on devices with IMEI RESET.
Flashable Roms used:
Nougat 7 Flashable - POTTER
potter-twrp-flashable-NPNS25.137-93-18-aroma
Stock rom Flashable Oreo 8.1 - POTTER
potter-twrp-flashable-OPSS28.85-17-6-2-aroma
I used the roms from this topic: https://forum.xda-developers.com/t/nougat-stock-rom-twrp-flashable-stock-builds.3813351/
Thank you so much @NZedPred , your topic saved me.
