So basically I unrooted my device using the script that someone had uploaded on here and it worked perfectly, the only thing that didn't was the wifi modem! I have had this issue when I rooted the device but lost my steps I did to fix my xt1575. I have tried to flash files individually and researched the error and have found its because the bootloader may have been relocked but it isn't. And in developer settings OEM unlocking is ticked and USB debugging is ticked. I tried to rerun the script with same results. If anybody who has had an issue could help me that would be greatly appreciated! :good:
Reflas the erase modem1 and 2 commands and the HLOS command too. No need to flash the rest of the files. If you need more help or this is not clear enough let me know.

The "script" you used is likely really old. The original way if rooting this device was by writing a pre-patched boot image, well, that works great until the radios change, which they have a couple times.
You can probably get this working by flashing an old modem image and firmware, but you are just getting more and more mixed up in versions.
The right way to fix this is restore your pre-root backup, or flash the matching unmodified boot image with fastboot, and then rooting properly.
Okay so I not that long time ago rooted my OnePlus 6t where I made a mistake in TWRP and deleted everything so I couldn't boot after I downloaded the os again and it started up fine and I had root access but my phone had no folder 0 and all there was in that folder so I can't download anything from chrome and I can't update my Google play service so can't get access to YouTube
If anybody knows how to fix this please tell
Use MSM tool!
You will have to unroot and lock bootloader again and use MSM tool to fully bring the phone back to Out of box state. Then you can redo again. MSM tool will repartition your phone all from scratch.

Hi guys,
I have a problem with my device. I recently had a problem with the sensors and I flash the persist.img of fastboot rom with twrp.
I lost WIDEVINE L1 and safetynet checks (only with ROM customs and without ROOT). I would like to know if there is a way to go back and "uncorrupt" the internal storage?

No l1 is gone forever, sorry mate
Doesn't it bring the Global Rom "davinci_global_images_V10.3.11.0.PFJMIXM_20190802.0000.00_9.0_global_ea6683ef55.tgz" 3.3GB with MI PC Suite to flash?
And bring the phone back to its original state?

I have not tried with the MI PC suite, by cons I tried several times with Mi flash, without success ...
In your opinion, should I try with MI PC SUITE?

Did you try the FASTBOOT file .tgz or the RECOVERY .zip?
There is no hope for us. Sorry

I'm sorry, I can't help but as someone who is looking at flashing a rom tomorrow, how do I avoid this from happening?
I would still like to use Netflix

It will flash back to factory settings and reset everything, I would backup and restore after doing so, with widevine though that will stay at level 3 and no chance of getting L1 back ever.

Don't flash persist.img unless it's from your phone, backup with twrp, you could even connect the phone to your PC and copy the persist.img file to your PC and use that if anything happened, the problem is people are extracting the persist.img file from the ROM and it's not the original file for the phone and flashing to correct faulty sensors, this breaks widevine and doesn't restore regardless if a ROM supports it, the phone doesn't anymore because it's now basically corrupt and can't be restored unless using the original persist.img.
I'm not sure I fully understand.
So I've unlocked my bootloader, I'm about to flash Twrp and a custom rom such as Pixel Experience or Havoc.
Am I right in saying this will have broken it already?
Before flashing I should backup everything in Twrp, I can then reviver only the persist part after flashing a room and things will be as normal but with a different rom?
I made a backup of ALL partitions (including the partition persist) 3 months ago that I transferred to my PC and that I later deleted, if I manage to find it with software like Recuva and restoring with TWRP, would it work?

I would say yes if you have the original files, you can try with those, if flashing from stock ROM that didn't belong to your phone then it won't work.

how did you flash persist.img? i dont use netflix anyways and same thing happened to me that happened to you, i just want to get persist.img back, help?
I also lost it for the same sensors fix reason.
Has anyone tried restoring a twrp backup from a working L1 device?
Can someone with untouched persist that still has L1 upload a twrp backup of their persist partition, please?
It probably won't work as the l1 keys are linked to each device individually but we lose nothing for trying.

Have flash any persist image from the fastboot ROM?
Yep, that's what I did. I didn't know that would break L1 but I wasn't using it anyway.

Hello,
In your opinion does the xiaomi warranty take care of this problem?

Do you have the backup of persist partition when your phone was L1 ? If yes, then try restoring it.

No I don't have. I have searched in various telegram groups to take persist backup on someone else (same device) and change serial number in it? Should I try that? There were people complaining that they were not able to install/update stock rom after doing this process. Please GUIDE, I am a beginner in these things....

You could try that but I am not sure if that would restore the wiped DRM keys. In some phones (Moto G5 Plus?), backup of persist from other phones would do no good.
Also you can try flashing stock ROM through AFT and see if it helps you.
An please REMEMBER TO TAKE BACKUP before attempting any of the above methods.

Already tried flashing stock rom via AFT, but Widevine stays at L3. I am not risking to flash persist of other device as it may lead to further issues. Please let me know if there is some more efficient way out of this issue. Thanks.
I heard flashing q firmware permanently causes issues with widevine l1. The only way to bring it back is to restore a previous persist backup or flash a qfil rom (not sure about the latter). If you don't have a backup, too bad chief.

Partially correct. QB1 update caused widevine downgrade to L3 but QB2 restored it to L1. Of course, you have to be bootloader locked all the time. Too many theories going around to restore L1 on UBL but none proven, even persist backup method isn't 100%
how to install qb2 bro please help need widevine
