You need to do this if you've flashed an Oreo 8.1 ROM and find that you can't get back to OOS because...
The ROM can't read /data so it hangs on the boot animation or reboots to recovery, even on a clean flash.
TWRP won't recognize your PIN/password or "default_password".
You've tried re-formatting /data from TWRP several times and it doesn't solve your problem.
Here is how to get back to 100% stock and/or restore factory encryption, which is different than Oreo 8.1 encryption:
1. Back up /sdcard to your PC as it will be erased with all of your files, pictures, music, etc.
2. Flash the stock recovery from bootloader.
Code:
fastboot flash recovery [I]stock_recovery.img[/I]
Latest OOS official stock recovery
Latest OOS beta stock recovery
3. Restore system setting in recovery.
This step is necessary to restore factory formatting and encryption of /data.
If a password/PIN is set, click “I forgot my password.”
Boot into stock recovery. Once there, go to Wipe data and cache > Reset system setting and Erase everything(Music, pics, etc.).
Note: If you don't do the "Erase everything..." option, factory encryption will not be reset.
4. Boot TWRP from bootloader.
You could flash TWRP and reboot to recovery, but TWRP will get overwritten with the stock recovery when OOS boots anyway. It's faster just to boot TWRP from a command prompt. Use the command:
Code:
fastboot boot [I]twrp-recovery.img[/I]
I recommend using using:
[RECOVERY][dumpling] TWRP 3.2.1-0 for Oreo (8.0 and 8.1) by codeworkx
5. While in TWRP, move “OOS...ROM.zip” to the SD card.
In Windows File Explorer, copy OOS...ROM.zip to the device.
Alternately, you may use the following ADB command from a command prompt
Code:
adb push [I]OOS...ROM.zip[/I] /sdcard/
Since OOS is a very large file (1.6GB), this will take 5-10 minutes.
Latest OOS signed flashable zip
Latest OOS beta (Oreo) flashable zip
6. Flash OOS...ROM.zip from TWRP.
7. Reboot system.
Your device will be formatted, encrypted and loaded with the stock recovery and ROM as it came from the factory. You may need to find the OOS...ROM.zip you pushed to /sdcard and delete it from emulated storage (/storage/emulated) if you don't see it at /sdcard after booting the ROM.
8. Optional: To re-lock your your bootloader, follow these additional steps:
This can only be done from a factory-supplied OOS ROM (including Oreo) with no modifications or the phone will not boot!
Enable USB debugging under Developer options.
Reboot to bootloader.
Unlock the bootloader with the following command:
Code:
fastboot oem lock
Return to Developer options and turn off "OEM unlocking"
Thank you for the write up .. nicely done :good:

It gave me an error 1 in TWRP. I had to do the following:
1) Make sure the bootloader remains unlocked
2) Back your apps up in TitaniumBackup
3) Back your /sdcard partition up on your computer so you don't lose anything
4) Reflash stock recovery in the bootloader
5) Boot into stock recovery and hit "forgot password" when it asks for your lock code
6) Boot back into bootloader and reflash TWRP
7) Place stock OOS zip onto the /sdcard partition
8) While you're in TWRP, flash stock recovery through its image flasher then reboot into recovery
9) Flash stock OOS, reboot, and then mod however you want

Will in 9th last step restoring from nandroid OB-1 work ?
It should I guess

Bump!
I made a big update to the OP today with more explanation, more detail and download links.
Thanks buddy, that tutorial worked perfectly!
The other way is to flash rollback image to Nougat in stock recovery.
https://goo.gl/YRyrt6
there are no other ways to revert back to stock OOS without affecting internal sd /sdcard ?
thanks for the guide above.
Ok I'm a bit Rusty. Flash from bootloader? Meaning adb? Then adb TWRP then boot to TWRP then flash stock room(s)?

Please do not quote the whole OP just to get someone's attention. A mention (@the Doctor) would suffice.
To answer your question, flash the stock recovery with the fastboot command:
Code:
fastboot flash recovery [I]stock_recovery.img[/I]
The only ADB command involved is "push" to get the ROM onto the sdcard in step 5.
Thx @the Doctor. My apologies.
Thanks for the writeup, I'll probably try soon and report back.
Thanks for this, may need it. Plan to flash DU 8.1 tomorrow. So you can't just restore an ob1 or ob2 nandroid from a custom ROM?

You can, but TWRP will not recognize your PIN or password while in OOS, so you'll have to set lockscreen security to none or swipe. Or you could do the procedure in the OP, then restore only data from your nandroid. You'll have to re-flash Magisk or any other mods after that.
I don't use a pin for backups or restores. Since I seem to have to format internal storage to get a custom ROM to boot, was just wondering if restore of oos nandroid works once on DU.

hello thanks for the guide just did this when i boot i cant connect to any wifi network thanks
How can I get my wifi back after reverting to 4.7.6? Ive tried EFS backup and everything possible but the only way to get wifi back is to flash an Oreo zip.

Have you flashed OOS Oreo Beta? My theory is that the firmware won't downgrade back to OOS 4.7.6, but I'm not sure. I've only restored back to OOS OB1/2, and wifi has worked perfectly every time.

Flashing Oreo beta is the only way to get it back as myself and others have found in the thread that was started on the subject. I hadn't seen that initially when I posted in here.
I was hopeful that following your method to a T would get me my wifi back on 4.7.6 but it wasn't meant to be. Absolutely nothing I have tried in the last 24 hours has worked to get it working on 4.7.6 including multiple clean and dirty flashes of the full 4.7.6 zip, twrp, stock recovery, restoring multiple backups, restoring EFS, factory reset, wipes, etc.
You might want to add that to the OP that if you revert to 4.7.6 that wifi will not work.

Are you using the latest twrp ? Also if decryption is not that important then try flashing Magisk after the 1st boot as it is known to sometimes cause bootloops and issues

try it and if didnt boot here are my steps if i remember correctly :
-flash latest global developer fastboot rom with mi flash (flash all , be careful with locking bootloader accidentally )
-wait until first boot before phone setup and don't go through it
-reboot to fastboot mode and flash nijel twrp
-reboot directly to recovery
-wipe->factory reset
-flash 8.11.26 pie
-reboot system
Exatly as for me. Flashed with nigel TWRP, with format data before. Few issues but CN firmware... Google must be installed.
ok will do that now and report
i flashed latest global then tried to flash with that recovery but nothing.
i am now going to flash china dev latest and try again
---------- Post added at 07:31 PM ---------- Previous post was at 07:24 PM ----------
so to be clear
i am gonna flash dev global 8.11.23 via fastboot
then wait for it to get to 1st set up screen but not go through the setup process
will then flash that twrp you mentioned via fastboot
and flash the rom after factory reset

i did exactly what you said again just to be sure
and it booted up with no problem
- mi flash->global 8.11.23 -> clean all
- first boot until welcome screen
- power off-> volume down+power -> fastboot and run "fastboot flash recovery nijeltwrp.img"
- volume up+power to boot to recovery
(so far if decryption goes well twrp shuold not request decryption password and you could mount data and see internal storage contents in /sdcard with no problem in twrp file manager)
- wipe->factory reset
- install pie zip rom 8.11.26
- wipe dalvik+cache
- reboot system
it took about 4 or 5 minutes for me to boot
If I've gone straight from the latest stock China ROM to xiaomi.eu 10.0.0.6.0 and have since flashed the latest nijel TWRP - which is all working fine.
Can I simply flash to this pie release or do I need to have previously flashed one of the developer ROMs?
Guys, quick conformation, please as I hear conflicting reports about MIUI Pie and my TWRP...
Please, from experience, decryption works, right? How about formatting data with TWRP and boot to Pie? Is MIUI Pie able to encrypt fresh data partition? And if yes is TWRP able to decrypt it again?
Thank you, feedback is really appreciated so I know what needs to be done for full Pie compatibility!!!

first thanks again for your great work on this recovery
decryption was good with oreo 8.11.15 china rom but right after pie rom boots and rebooting to recovery, decryption fails
from there rebooting to recovery again doesn't change anything ... recovery asks for decryption password every time.
and cuz data partition is not mounted so recovery log will not be saved to internal memory to attach it here
after formatting data miui boots successfully and encrypts data again.setting up the phone and rebooting to recovery ... but same thing happens and decryption fails.
I am stuck at encryption failed when I flash stock oreo rom. I tried formatting data using twrp and flashed no encryption file as well but nothing works.:crying::crying::crying:
I just want to use the stock oreo rom again with root.
Pls help:crying:

I used partition dl mode to flash the stock oreo rom over 7.0 to keep the root. Then i flashed custom kernal for stock 8.0 but it didnt work. I have done the same procedure before and it has worked like a charm. But it keeps on giving the encrytion error when i try it now

Odd. If I had to guess anything, it would be that not all the partitions were flashed when going from Nougat to Oreo.
I once flash a Nougat ROM from an Oreo ROM and I had the same encryption issue and lost everything.
That was the last time I would trust myself again and not do a backup.

I tried that as well. With stock recovery is says data is corrupted and doesn't do anything. I think it might be a problem with patched lg up because when i use normal lg up to flash oreo it works. But I cant root then.
I would try changing to 3.2.3-4 TWRP and then trying the procedure again. It seems that the 3.3.0 TWRP does not decrypt properly sometimes.
In the same boat as OP

Hi
Looking for a way to keep TWRP and root ... any help appreciated
I've got a US996 with the same issue as the op. I have the latest TWRP 3.3.1-0. The phone was working fine until I upgraded twrp but I might have done a mistake resetting phone outside of twrp.
I can still get back into twrp but I haven't been able to install zip files without getting that decryption unsuccessful message when booting to system.
When getting back into TWRP using hardware buttons sometimes there is a prompt asking "keep system read only?" which I never chose and swipe to allow modification. I think this happens after
I pull the battery after getting the decryption unsuccessful message. There is a reset system that I could chose under the decryption unsuccessful message but I'm assuming that will make me lose twrp
...but if my phone is a us996 and is still
unlocked, would it matter if I did select it? Wouldn't I be able to reinstall twrp using adb again on a computer after Oreo is reinstalled?
To do Prowler_gr's suggestion which guide do I follow (sounds like I should do the second option)

Don't blame me if this goes wrong but I'm pretty much 100% certain that you mush press the rest button. This has happened to me a few times I'm sure. You won't loose twrp. Whatever resetting goes on in the background I don't think it's an actual Factory Reset.
Edit: Just to be clear you taking about a white screen with I think in dark blue or black text ENCRYPTION UNSUCCESSFUL and something like "reset phone" option directly under it, on the upper half of the screen?
Hi ezzony
Yes you are thinking of the right decryption unsuccessful page. I get it when booting to system
after installing Oreo and magisk 19 and having wiped everything (format data too). I will get the exact wording of it tonight
Thanks!

Why did you used fastboot rom instead of the recovery rom? This way you didn't update the rom but reinstalled it. So I think that the only way to get rid of the password request is to format data partition from recovery and then install magisk. Next time you have to update you have to download the RECOVERY rom, dirty flash it and flash magisk before rebooting to system.

You have to flash twrp reboot to recovery if it asks for a password format data then install magisk. Vbmeta is needed just when you change rom from miui to aosp, so in this case you don't need it
