Hi
I used this method to install LOS 15.1 on my H918. But now i have to restore the stock os on it.
The normal way would be to restore download mode from recovery/twrp and use LGUP to flash a kdz.
The Problem is, that i don’t have twrp on the recovery partition. Using the above guide you install twrp to the laf and flash twrp to recovery from there. But flashing the recovery never worked so i used the laf/twrp to flash LOS.
I have several ideas, but i’m unsure which one would work:
Use the stock recovery, as it’s still on the recovery partition
Reflash the laf/downloadmode from the laf/twrp itself
Reflash downloadmode via adb shell
Btw: The phone is on ARB1

If you used laf exploit then twrp is on the laf partition (download mode) boot into it and twrp should load, from within, flash twrp as an image and point it to recovery. To restore download mode go to the lafexploit thread there's a zip to restore the laf partition

Like i said, that is exactly my problem. Flashing twrp to recovery did not work. It will flash without error, but then boot the old recovery. That’s why i’m asking what other options i have.

Hello, you fixed the problem? i lost the imeis but restore it with a QCN Backup, but i dont have signal... thanks for your help
i find the fix: thanks to tommyb2 in Lenovo english forum for the tip
As it looks like you damaged your qcn you need a new one !
is your WiFi working ??
if not try this first !
enter Fastboot
then
Fastboot erase persist
Fastboot flash persist persist.img
(your WiFi should be back)
try
Fastboot erase Modem
then
Fastboot flash Modem non-hlos.img
After that Fastboot reboot !
maybe also your imei ?!
if not get a QCN, enter Diag mode (see page 12-13)
and replace it with a new one !
with an imei editor you can put in your imei
The Files you found in your current ROM !
Non-hlos.bin has to be renamed to.img

Hello, I also deleted imei info by mistake, can you provide with a dummy lenovo z6 pro QCN file, so I can restore mine? Thank you
Is all lost?
It's been a few days and no replays, let me guess I can trow the phone away ? since there is no QCN file available for restoring
Don't throw away. Get a sain QCN file, put your emei in it and flash back.

I leave you mine with a random imei, change it to yours and tell me if works (change the extension to QCN)
something happened
Thank you for the qcn file, it did help but not nearly enough.
Any other ideas on how to fix this ? I'm giving up on this 'cuz it seems so ...... chinese .
Edit1: Do I need to change MEID or any other unique ids ?

mied, is part of the imei... not neccesary to modify...
now, do this:
enter Fastboot
then
Fastboot erase persist
Fastboot flash persist persist.img
Fastboot erase Modem
Fastboot flash Modem non-hlos.img
Fastboot reboot
I'm sorry it took so long to respond but I was on a trip.
It works, I've got my signal back, but sometimes when I start a conversation the other person hears bad, like when you speak underwater. It doesn't happen when I put my headphones(not yet anyway),
but I guess this will be solved in the future updates.
Thank you very much :victory: :good:
Issue persist after upgrading
Hey....again
After upgrading to 11.0.325ST -> from This post.
I lost the signal again.
Doing "fastboot erase persist
fastboot flash persist persist.img
fastboot erase modem
fastboot flash modem NON-HLOS.img
fastboot reboot " does not help.
Any Idea on how to get back the signal ?
Thank you,

As a note that QCN file give a warning that my model no. doesn't match when restoring, but it works on stock ROW rom.

Hi, if you are on ROW, update through OTA to 11.0.350. Many Z6 owners have reported it fixed connexion issues. It might help you as well!

Hello,
Sometimes i can;t because phone is rooted, sometimes when i get OTA update I can't install because after i press "update" it resets to changelog.
Also when I try to update through .ZIP file it fails and I lose signal.
Zip file name : L78051_ROW_SECURE_USER_Q00745.01_P_ROW_11.0.284_ST_190810_TO_L78051_ROW_SECURE_USER_Q00745.01_P_ROW_11.0.325_ST_190918 (renamed to update.zip)
Thank you,
One way or another, you need to find a way to update your phone to latest ROW rom which is 11.0.350.
Try unrooting and flashing back stock recovery. Otherwise find a full rom file that can be flashed with fastboot.
My issue is not with the version. My issue is with qcn file for my signal.
Most likely I will need a new dummy QCN file from Lenovo z6 pro from latest ROW rom version, change the dummy imei to my imei and restore.
Most likely x-geo will have a good idea of what I must do, 'cuz last time he solved my signal issue. If you have Lenovo z6 pro with latest rom you can back up your QCN file set a dummy
imei and send it over and I'll try and/ restore my phone, that will be greatly appreciated.
Thank you,
Liste, updating to 11.0.350 solved communication issue of many users !!!
May be it resets proper QCN partition or whatever. Anyway there is no point in staying with earlier ROW version they are crap !

Download your phone firmware and miflash tool, flash via fastboot with this software but DONT re lock the bootloader

Did that many times brother but it is still stuck in bootloop. The problem is that i have damaged EFS Partition. Ihave tried installing ROM through TWRP and also through fastboot with miflash. When i enter in Mi recovery i get message of " NV data corrupted".

You need to fix the partitions i think (idk how, but try on TWRP, there is a option to fix partitions) or in last case with fastboot i think its possible

Download stock rom and upack to the C:
copy this files from adb to the rom https://cs5-2.4pda.to/16762384/05.png?bc48fd2c50cba18a8da8778c9cdc19a9
run flash_all.bat
DONT USE FLASH_ALL_LOCK.BAT IF YOU FLASHNING GLOBAL ROM ON K20, THATS BRICKED YOUR PHONE...
If non of the above works than you can try this: https://romprovider.com/2020/03/xiaomi-mi-9t-imei-repair/
I know that i used something very similar when rebuilding EFS on my old Mi A1 and it did work. Though i didnt try it on Mi 9T because i didnt need it yet.

Ok brother. Let me give it a try.
Hey Bro, don't worry at all! It's because of EFS Corruption and you have to clear the partition and then flash ROM again with fastboot!
Boot into TWRP recovery.
From TWRP’s main screen, select Advanced » then Terminal.
Type the following commands in terminal (one by one):
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1
dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2
Reboot device.
go to TWRP, Flash ROM
So I unlocked bootloader on my redmi note 7.
Then I flashed twrp and rooted my device.
Then I flashed pixel experience but it stuck on the Google logo after reboot. I tried factory reset in twrp but it didn't work.
So I restored the backup I did before flashing pixel experience.
And then my phone stuck on bootloop.
So I booted into fastboot mode and flashed the fastboot rom and it worked. I have successfully unbricked my device.
But now it shows "find device storage corrupted your device is unsafe now"
Everything works fine except I can't turn on find device and also can't install miui ota updates via twrp.
(And also when flashing twrp for the first time when I reboot it showed the stock recovery because I hadn't flashed disable dm-verify because when I am in twrp and try to mount my system to my computer my phone doesn't show up in the computer. So first I copied the disable dm-verify file then again flashed twrp then booted into twrp and then flashed disable dm-verify. I don't know if it is necessary to format data when flashing twrp. Maybe that's why the problem occured. I don't know.)
Please help.
Thank you.
Extract persist.img from official fastboot rom and replace the existing persist in Orangefox.
At least it helped me.
Persist.img flash through recovery gonna fix the problem but forget about Netflix and L1!!
Personally speaking had that problem with corrupted message pop up every time i reboot my device and when i flashed the persist.img through OrangeFox recovery i lost L1 forever (and there is no turning back).
If you wanna try that method i highly suggest you to Backup your Persist Partition first.
Yes, but isn't the original persist partition already lost, when you get the "storage corrupted" message?

I tried may hours to define the problem's source but i think that's unclear in every situation. Others say that's a persist.img corruption while others had that problem with Mi Account corruption, etc.
Mine corrupted message came when i tried to flash Global Official MIUI in a EU variant device through normal process that doesn't engage any kind of Persist partition rewrite.
I had a backup of persist.img and flashed original from EU fastboot file and finally after that I repatch my old persist.img. The first time i did that process my device and L1 worked properly (even that spam message disappeared) but after a long time that I tried same process for same problem i completely lost my L1 [strange af!].
So, a safe process to try now is to flash back the official fastboot image of your variant (Erase + Lock [for L1]) through MiFlash tool and check that corruption message if it goes away (be careful to flash the correct fastboot image or you will get a a bricked device).
In conclusion it's Extremely advisable to keep a full backup of your partitions and especially Persist partition if you wanna flash Roms and generally unlock bootloader!

Always use OrangeFox for Lavender here is the link (download and test with latest R10.1_02-Stable)
I see the splash screen with NOTHING logo and "Powered by Android" at the bottom. After 15 seconds or so, the phone reboots.
This started happening after I erased the persist partition using fastboot.
A few things I tried which didn't work:
Sideloading a full 1.1.4 hotfix zip file using adb.
Factory resetting from the recovery and fastboot.
Format persist partition as ext4, "fastboot format:ext4 persist".
I don't see persist.img included in the firmware release. Can anyone extract the persist partition from their Nothing Phone (1)? I can flash persist.img and hopefully get the phone to boot properly.
Or if it's possible to enable diag mode from the recovery image. I don't know if it's possible to set sys.usb.config to diag,adb on recovery. I took a qcn backup beforehand. I can just restore that.
Thanks to @ayed78 providing persist.img from their device, I was able to boot into Android. I restored the qcn backup to restore the IMEIs and therefore restore cellular network connectivity.

Great! Keep me posted.
Posting a short version of my reply here, from https://forum.xda-developers.com/t/how-to-unbrick-nothing-phone-1-fastboot-bootloop.4501439/
I've tried this on my Nothing Phone (1) EEA version which bootloops. It doesn't work. Whilst booting from the A slot, there's the 15 seconds of splash screen, then it reboots, same as before.
Flashing to A slot was completed without any errors. I don't think this super image includes the persist partition. My phone started bootlooping after I erased the persist partition. Can anyone upload their persist partition for the global or EEA version?
