Can't get back to Stock ROM (what am I doing wrong?)

History of what I did:
I first installed the first small OTA Update to 4.5.1 then unlocked the Bootloader and flashed TWRP v46 from xdvs23. And made a full TWRP Backup and flashed Magisk afterwards.
Everything worked fine until I debloated the System and wanted to make the OTA Update to 4.5.2 (1,5 GB), which didn't work. After I flashed it, the phone didnt boot anymore. So I restored the TWRP Backup, which doesn't work either.
Current status:
TWRP v58 is flashed and works. I can flash ExcperienceOS from Jamal, which works fine, too. But flashing the OTA file doesn't work and restoring my backup wont work either -_-
I would really appreciate help to get back to an OTA updatable version of OxygenOS!

If you still have the TWRP installed I would download the full 4.5.2 zip (Listed elsewhere on these forums) and use adb sideload to install it, then proceed again from there.

I did that several times. It doesn't work sadly... I get into a bootloop

You didn't erase your userdata partition by mistake did you? You could try going into fastboot mode and use the command:
fastboot format userdata
Obviously this will wipe the userdata partition but the phone is acting like there's no userdata partition anyway

I might have, I will try that, thanks

Or just wipe everything, flash stock recovery, and flash Full OxygenOS zip.

I formated the userdata and flashed the .zip from the link, but I still get a bootloop...
I still don't understand what I am doing wrong...

How about trying to wipe everything from wipe menu except internal storage and then flash the oos zip followed by lazy flasher zip from here - bit.ly/lazyflasher
If this doesn't work then try changing to a different version of TWRP!

You didn't do these steps wrong by any chance?
Steps To Disable Forced Encryption i.e, Decrypt Data
1. At first time when you open twrp, it will ask you to allow system modification.
2. Allow it and then flash the no-verity-opt-encrypt.zip file .
3. Then Go to Wipe-->Format Data.
4. Type Yes to confirm wiping of Internal Storage.
5. Now you have decrypted the data sucessfully.
Note: Dont try to restore the nanodroid backup which you have taken before. It may end in bootloop.

ok, there I see what caused my first bootloop. Thanks
But why doesn't flashing the Stock ROM .ZIP work on an wiped (fastboot format userdata) phone? What else do I have to do?
EDIT:
*** solved ***
I failed hard. Luckily the OnePlus Support is excellent and was able to fix my issue with a remote session using their official tools. The Phone and I are both happy again.
Thanks for all the help, though. I learned quite a lot while dealing with this issue. It's a very kind and nice community here

Flashing a Rom using TWRP

Can I flash back to Oreo using twrp on the essential phone or no?

Not sure if you can or not, but follow this thread as it's a better option. Has all stock images available and it's essentially a one click solution.

You cannot, must fastboot -w first and if u format in twrp you will break verity and have to flash the fixer kernel(bootred.img)so yeah u can but its not a quick fix. I would backup data and wipe and then copy the important stuff back on to it

Wifi Wi-Fi is broken after restore backup data and system with TRWP, solutions?

hi guys
after restoring twrp backup (data and system)
WIFI is broken, no way to make it work again, even restoring persist backup from twrp or flashing the original persist
not either deleting file contect of wifi_mac.bin in root/persist
does anyone know how to make wifi working again after TWRP restore of data and system?
differently TWRP is totally useless for backup in Mi A2 at the current state.

flash the original boot.img from the same system version installed in your device.
If V9.6.15.0.ODIMIFE, download the same OTA image version package, unzip it, get only boot.img and use fastboot to flash it into your device.
fastboot flash boot_b boot.img
fastboot flash boot_a boot.img
I hope this works

Flash this kernel from temp twrp. https://forum.xda-developers.com/mi-a2/development/kernel-hex-t3855773
It worked for me.

Tnx man. After flash kernel magisk doesn work.
How do i reinstall magisk now? You Need the "patch boot Image" method in order to support OTA. But boot Image now is not stock, cause It s updated with the new kernel so i cant use the official boot.img , should extract the new One from My device? How?
Or should i flash magisk 17.1 from TWRP? But still cant, because TWRP install s It in Active slot offline TWRP (at the moment) and not in the needed boot partition.
****, help It s getting too annoying ahahah

Download the magisk zip and boot into twrp and just flash it. You can switch the partitions in twrp and flash magisk. Just don't reboot twrp after switching the partitions.The latest twrp from Tingyichen can be downloaded from this thread.
https://forum.xda-developers.com/mi-a2/development/recovery-unofficial-twrp-recovery-mi-a2-t3825146
the command is fastboot boot twrp-3.2.3-jasmine-20181020.img and it goes straight into twrp with no flashing required.

booting directly in twrp with command and without flashing it in any partion caused me bootloop and data wipe, also have read this in another thread (twrp one)

Did you use the latest one from 20/10?

[HELP!] persist.img on wrong partition?

Hi all! I was trying to flash new MIUI 11 and after some flash my Wifi won't turn on!
I read about it on internet and tried to flash persist.img (Fastboot flash ROM doesn't flash this file)
I tried this comand:
dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27
and also
dd if=/sdcard/persist.img of=/dev/block/mmcblk0p26
Reboot and now my Wifi is working, but camera not! The popup camera makes strange noise and tell me that can't be reclosed.
Please, how can i restore those partitions? Can someone backup your mmcblk0p27 and mmcblk0p26 and send to me?
PLEASE!
UPDATE: I did the calibration for popup camera, now it pops out and retract but it make a strange noise again

flash stock fastboot rom

Seriously !!
remove this and post it in the appropriate section.

Hello, good day, you need to flash persit.img on TWRP, the problem is with all roms, including the rom stock, the solution for me was to flash persit.img through TWRP on xiaomi.eu with miui 11, this after of installing xiaomi.eu.

Attention guys,
Reflashing persist will break your Widevine L1 permanently!

Whenever you flash back stock ROM it should say device storage corrupted at the setup and every reboot

Just boot into twrp if you have one, I use this one and it works fine for me at least on AOSP ROMs and the persist backup and restore https://drive.google.com/file/d/1TSGqgarTA8yDfH0KUYSgZkGyRA_qm_vF/view
Then select backup and then select the persist partition or if you want to back up everything you can . Back it up to your internal storage then after copy it to your pc or any form of storage you have so if anything goes wrong with the persist partition just copy it back and restore it.

Good just restore only the persist partition and it should be fixed

@Benfatica Im currently on miui.eu and back up was created on Global stable ROM. Its ok to restore on this ROM or must be restored on Global ROM?
Restore via twrp right?

Ok glad I could hel,if you didn't have that back the only solution will be to flash the persist image from the fastboot ROM , and that will also break you windvine L1. So always keep a back up of the persist partition some where, because this phones persist partition gets corrupted a lot if you like flashing ROMs.
