Edit: solution added
problem:
after flashing a rom (in my case OP3lite or FreedomOS) you can't get past the boot logo
you have access to TWRP, so you can restore nandroid or flash flashable stock OxygenOS packages (tutorial here)
solution:
wipe: Dalvik /ART Cache, Cache, Data, System
flash your rom
try to boot (most likely will get stuck at boot logo)
boot into TWRP > Advanced > Fix Contexts, and swipe to Fix Contexts
Reboot
(wait a while, it might take a few minutes till it boots)

original post:
hi,
I'm running official OxygenOS 3.1.3.
Rooted (systemless) , TWRP installed.
I don't have any problems on my rom, but everytime I flash a rom I get stuck at the boot logo.
I can just force reboot, goto twrp and restore my nandroid backup, and my phone works fine again.
But I can't flash any rom.
tried this:
Dirty flash OP3Lite rom - stuck at boot logo
wipe and install OP3Lite rom - stuck at boot logo
Restored nandroid backup, factory format, wipe and install OP3Lite rom - stuck at boot logo
wipe and install FreedomOS - stuck at boot logo
Restored nandroid backup, factory format, wipe and install FreedomOS - stuck at boot logo
wipe, Format userdata throught fastboot, install FreedomOS - stuck at boot logo
update to OxygenOS 3.2.1 (flashable zip throught twrp)
wipe and install FreedomOS - stuck at boot logo
Both roms I tried are OxygenOS 3.2.1 stock based, my problem is most likely not due to the rom I want to flash.
Anyone knows a solution for this?
is it possible that systemless root causes this problem?
are you encrypted? that might be the issue.
backup your internal sd data then go to fastboot and fastboot format userdata then flash the rom you want

I never did format my userdata throught fastboot, so I might be encrypted.
I'll try tomorrow and let you know if that was the solution.
@Abaddon I format my userdata throught fastboot (fastboot format userdata), but still roms wont go past the Logo . any other idea?
did you full wipe?
wiped /system too before flashing a rom then u go and flash the rom + gapps if needed
how long was it at the boot logo? no animation correct?
did u advance wipe - data, caches, system instead of factory wipe, try it 3 times
I did a few wipe 3 times, still stuck at logo.
I get stuck on this logo, never reboot, just get stuck there.
I noticed that it does flash the rom, cause if I restore my nanodroid backup layers and adblock is added.
I also get zero error while flashing in twrp.
I fixed it .
did a fill whipe, then flashed feedomOS, then tried to boot, didnt get past the logo, booted into recovery, selected "fix Contexts" and then rebooted, started without any problem .
doesent work for me..!! any help

Faced this issue every time I restore any nandroid on one plus 3. It stucks at rotating resurrection logot . Even tried fix contents from TWRP, no output. Please help without a functional TWRP backup and restore - phone is useless. Only everytime mega unbrick guide needs to be repeated with painful reinstall of apps
hello guys. sorry if I'm a bit slow on this topic. I'm using the the op3t A3010 version (not dure whether I'm at the right forum or not lol) Recently I updated my phone to the new 4.1.7, in which I had already rooted the phone before with magisk v12. But right after the update, as usual, the phone will unroot and yes I did root the phone back by using the magisk v13.0 version. But it failed the safety net. So after a few 'research', I installed the superuser just in case that the safety net will work this time. But this is when it all went wrong. The phone did restart back to factory settings, but the phone is not rooted (checked by using the rootchecker app) So again, I'm back to the twrp recovery, clean wipe all the data, with hope that I can start from scratch which is from installing the magisk all over again. But after this step, it stuck at the boot logo for like more than half an hour. Than at this moment, I restart my phone back to recovery mode by long pressing the power button, and when I try to install both the magisk 12 and 13 version, there is a line of error code on the screen. There's a site that says simply go to the advance setting on the twrp interface, check fix contents and ur phone will be as good as new. After done doing that, I'm now stuck with a phone with no os installed and about 38% battery left. Can anyone help me here? This is the only phone that I had :crying: Urgent help needed here guys
Unless your original installation is without storage encryption (no dm-verity) this will happen. So next time install custom rom after flashing OB22 firmware+modem, then boot patch for dm-verity followed with custom rom and gapps then boot without wipe
i have the same problem but with p9 lite : when i tried a flash lineageOS or ResurrectionRemix my phone stucks at boot logo and when i flash the original os my phone works perfectly
sorry for my english

So I was running stock 4.0.0 with twrp recovery just fine, and go to update via ota the 4.0.1. Now this failed, and so I decided I might as well clean install. After installation now, regardless of rom (even lineageos based) I cannot boot out of twrp. Every reboot leads back to twrp. I can access fastboot, but thats it. I've tried reflashing twrp also
Edit: This is ridiculous. Literally everything looks perfect but it refuses to boot. Tried every rom I can, even tried different recoveries and ****ing nothing. I can't find any rhyme or reason to this nonsense.

I'll tell you exactly the same as the last one...
First of all... YOU can NEVER try to install an official update having a custom recovery (like TWRP) installed in your device. Previously, you should have changed to stock recovery.
Having said that, you have to make the following....
1. If you have already the full room into internal memory, reboot into recovery. If not, copy the full rom to a pendrive an connect it by OTG.
2. Restart in recovery mode and click on wipe and then, advance wipe and select... davilk, cache, data and system partitions. then, slide the bar.
3. When it finish, go back to the main menu and click on install. Select the full rom from internal storage (or OTG) and install it.
4. When it finishs, you have two options from here...
4.1. First option. Try to install TWRP recovery before rebooting, because the rom will have installed stock recovery. After flashing twrp, theoretically you should get twrp installed but sometimes it fails. So, It is possible it is blocked when you try to reboot system and you can see a warming saying "there is not rom installed". Don't panic, turn off your phone from power bottom and restart the device. You will see the room installed but not the twrp. In this case, you will have to install TWRP from sideload and then, Supersu from recovery.
4.2. Second option. When the rom instalation has a finished, reboot system to check the rom is installed correctly. Then, restart again your device to fastboot mode and install recovery twrp from sideload. Finally, you can install Supersu from recovery.
This is all! Never settle!

You don't do that with adb but with Fastboot
Boot into fastboot > fastboot flash recovery-file name.img
Here's what I had to do: flash the new stock recovery in fastboot rather than twrp at all, then boot to it FROM fastboot. Sideload the full firmware (4.0.0, 4.0.1 either should work) and reboot/power off. My phone seemingly bricked at this stage but playing around with the buttons got me back into stock recovery where I got the option to decrypt and wipe. After this it booted up unto a fresh install of 4.0.1.

OK I get all of it so basically I flash stock recovery from fast boot, boot into the new stock recovery via fast boot, then flash ROM and I'm done?
OTA works ONLY if you are on stock recovery, rom, kernel.
I suggest to format data in recovery (this will wipe ALL in youre phone),
flash modified recovery (.22, .23. 28 by eng.stk),
flash FULL rom,
flash SuperSU 2.79 stable, if you want root,
flash recovery,
reboot to recovery,
reboot to rom.

Where can I get the stock recovery download?
something like that happen to me when i try to go back from N to MM oxygen, i managed to fixed it by installing the stock recovery then install the 3.26 plus the 3.26 "modem" (if i didnt install this one, my touch screen wouldnt work) after that it just works, then i updated to 3.28
i havent install twrp and do the root for now because dont have time to tinker yet, but i can just do than whenever i have the time
I think ---- and my solution
I think some script is created as we click update...It's running on boot up and causing this problem...
I had this problem yesterday and it took me a lot of time to get my device to working...
SOLUTION: first backup the data(it backsup apps and such) from twrp and other files which are important for you...copy it to a PC.
follow the second step in this thread(it will wipe everything)
It's not allowing me to post link...It's the mega unbrick guide from Oneplus3 forums
It will take you to older version and then flash full zip(nougat build) from modded twrp..restore the backup..don't update until someone finds a solution...I did that and I'm waiting for a solution to continue...
hope it helps
This is how I solved mine.
1) Go back to stock recovery v2
2) adb sideload oos, flash magisk then flash systemless supersu.

You can grab the stock recovery in the OP3 toolkit here on xda
https://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Flash through fastboot, then flash/sideload a full stock zip. After that your phone should be back in working order and you can flash TWRP back.
Goodluck!

If my phone is rooted, flashing through fastboot the stock recovery will remove root?
Hi,
My Nexus 5X died some days ago, and Google shiped me another one. But this new device have the unbelievable "NO RPMB" message that locks the bootloader (this is a known issue where the bootloader is automatically re-locked after each reboot, making flashing factory images an harassing journey).
I installed TWRP to flash a custom rom but after each reboot on the system,TWRP was replaced by stock recovery !
Do anyone knows how resolve this problem ? I suppose if I can flash a custom rom it will solve a great part of the problem... I'm actually thinking of sell this new phone and get another device like oneplus.
Any help will be appreciated ! ?

Unlock bootloader, flash TWRP and boot straight to recovery without rebooting, perform a factory reset and root. That should make TWRP stick. If it doesn't, you can then use the TWRP manager to install TWRP again.

Quick question. As I just picked up a refurb N5X on the cheap and I plan to use it (fingers crossed it does have RPMB, not holding my breath though)- how viable are custom ROMs on this thing? The reddit thread that started this all states to leave /system unmodified but other comments say that they've flashed custom kernels.
So- if this is the case, would the order be unlock bootloader>flash stock images/noencrypt>flash TWRP>boot into TWRP> factory reset> boot into Oreo> unlock bootloader and boot into TWRP when modifications need to be made?
Thanks.

I use a custom kernel so that works just fine, haven't tried a custom ROM though. You don't have to unlock the bootloader every time to make changes as long as you have TWRP. I'm not entirely sure but I think rooting made the TWRP stick. If not, you can still install it from the TWRP app as you have root.
After you've installed the stock images, it should be enough to boot into TWRP, do a factory reset and flash the custom ROM.

So once TWRP is installed and "stuck", it can make modifications to traditionally "root" partitions (system, data, etc.?).
Also, did you flash the noforce encrypt boot image (and then wiping userdata)? Or does the stock image work?

Hello, i have the same NO RPMB problem Im using latest stock rom 8.1 (December patch), radio, bootloader and vendor.
How can i boot straight into recovery without rebooting? Do i need to flash vendor.img too? (i would like flash latest AEX rom).
If im not wrong i should do this procedure as suggested right?
- unlock bootloader from fastboot
- flash latest twrp recovery from fastboot without rebooting (this will work? Because in the N5X root thread it's written to reboot first)
- get into twrp without rebooting (how do that?)
- install root (i will use latest Magisk)
- perform factory reset
- wipe system, data, cache, and dalvik cache
- install custom rom, gapps...
- wipe cache and dalvik, and reboot
Finally i will have a rooted device with custom rom and bootloader locked again right?
Or is preferred this solution of Reddit user?

I haven't tried this with a custom ROM but I would try it like this.
- Unlock bootloader from fastboot
- Flash TWRP from fastboot
- Select boot to recovery from the fastboot menu
- Do a factory reset
- Wipe system, cache, and dalvik cache
- Flash ROM, flash Gapps
- Flash Magisk
- Reboot
Used the search, used google, couldn't find any concrete answers
I am on Android N - unlocked bootloader - rooted via magisk, One Plus 3.
Could I do the following?
use TWRP to make a Nandroid Backup (System+Data+Boot) of my current set-up
then, manually flash (using twrp) Android O
find out I don't particularly like it
Go back to TWRP and Nandroid Restore back to Android N, as if no update ever happened
Or will there be issues?
Thanks
I do that with freedomos. 2.17(N)>3.1(O)>2.17. I restore nandroid and reflash rom

Should have mentioned I'm using stock rom.
So I'd restore the nandroid via twrp, and I should be good to go?

There won't be any issue. You are alright with the procedure. Just make sure you use the correct twrp recovery for oreo coz if you use the non compatible recovery then you won't be able to boot into recovery once the oreo is flashed and you are forced to go with the stock recovery
Process I followed when I tried oreo last week
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Do factory reset(wipe everything except internal storage) then flash oreo twrp image. Perform reboot. (no OS warning on reboot option screen will appear) just ignore it. It will boot to recovery even without the OS.
Once booted back to new recovery(oreo twrp)
Flash oreo stock zip and again flash oreo twrp image and reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu. Reboot to OS
Enjoy oreo
To go back to nougat
Reboot to recovery.
Perform factory reset as mentioned above.
Restore everything except bootloader, cache and dalvik cache
Flash nougat twrp recovery. Reboot to system.
Happy flashing.
Edit : use blu sparks recovery for nougat backup.

There won't be any issue. You are alright with the procedure. Just make sure you use the correct twrp recovery for oreo coz if you use the non compatible recovery then you won't be able to boot into recovery once the oreo is flashed and you are forced to go with the stock recovery
Process I followed when I tried oreo last week
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Do factory reset(wipe everything except internal storage) then flash oreo twrp image. Perform reboot. (no OS warning on reboot option screen will appear) just ignore it. It will boot to recovery even without the OS.
Once booted back to new recovery(oreo twrp)
Flash oreo stock zip and again flash oreo twrp image and reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu. Reboot to OS
Enjoy oreo
To go back to nougat
Reboot to recovery.
Perform factory reset as mentioned above.
Restore everything except bootloader, cache and dalvik cache
Flash nougat twrp recovery. Reboot to system.
Happy flashing.
Edit : use blu sparks recovery for nougat backup.

Go to twrp - advanced - file manager - go to root folder - data - system - and delete files with .key extension. There will be 2 files delete both and reboot.

Thank you very much and that worked. I am back in the system.
BTW in your original instructions I had to re flash rom after restoring twrp backup otherwise it didn't boot and stuck at rom animation.

This should not have happened, anyways delete all those files which I've highlighted in the image below. This will reset the lock settings.
Oh sorry I forgot to attach the file. Here it is.

Hi, OP here. Thanks for this guide.
Unfortunately, it did not work out for me.
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Done
Do factory reset(wipe everything except internal storage)
Wiped fine although I got an error of not being able to wipe 'USB-OTG' or whatever it's called. I ignored it and moved on.
then flash oreo twrp image.
I googled oreo twrp image and got an img file with filename "TWRP-Oreo-OnePlus-3-3T". When I installed the img, it asked the options to choose Boot, System, or Recovery - so I chose System.
Then I rebooted and went back to recovery.
Flash oreo stock zip
flash oreo twrp image
Done
reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu.
This is where it ends. I get stuck at the OnePlus loading screen and forced reboot into twrp and flashed magisk. Once I boot up the OS, I get stuck at the OnePlus logo and that's it.
I actually re-did ALL of the steps again (in case I made a mistake) and still, the same issue. No progression.
Once I gave up on Oreo, I decided to go restore my nandroid
Reboot to recovery. Perform factory reset as mentioned above.
Wiped
Restore everything except bootloader, cache and dalvik cache
Here's the issue:
I press Restore (I uncheck both bootloader and cache, but there's no option for a specific dalvik cache- unless I'm not looking hard enough?) and I get the 255 Error.
Flash nougat twrp recovery. Reboot to system.
I tried to ignore that error and flash the twrp recovery.
Rebooted and it took me to fastboot. Regardless of I keep trying to reboot system it won't work.
I actually made two separate nandroid backups (the same 'everything except system image' as you've described) in case one of the backups was corrupted. Both backups ended up with the same error.
I got too tired of all these errors and just found a stock recovery and ROM and flashed it back. Now, all my apps and settings are gone. To be honest, I just want my phone back to where it was with Nougat.
Can anyone assist me?
@maxs8007, Like I said I did that already but nope still same issue. It wouldn't let me do matter what I did.

Buddy from my experience the whole thing too finicky and am thinking just factory reset and stick with stock rom. I wasted so much time already. Everytime I get different error, probably recoveries still not fully compatible with Oreo.

Could you please tell me what error you get on the lock screen? Could you post an image so that I can get a better idea of what's happening with your device? Also could you please confirm which files have you deleted? This time you need to delete 5 files which are related to lock screen setting and those are the only files responsible for lock settings on the device. I'm somewhat confused because I never ran into such issue while I did the oreo thing
If you have decided to flash stock then just make a backup of data partition so that you won't loose your data and you can easily restore it via twrp.

I read the entire post and here what I've to say. The above quoted steps is where you went wrong. The recovery needs to to be flashed as a recovery and not as system.
In your case the nougat recovery was never replaced with the oreo recovery because you flashed it as a system. This is where it went wrong. Sorry for the dalvik cache and USB - otg, I didn't mentioned about them. Those are the least important points in flashing though I should have mentioned that already
The next thing you mentioned is you went back to recovery which at that moment was nougat recovery and not oreo recovery. I'll link the modded recovery I used for oreo below
The next thing you did is you flashed oreo zip and again flashed the oreo recovery but as you flashed the recovery as system, the oreo stock rom was automatically replaced with recovery because you flashed it as system and the device didn't boot because there was no android OS to boot up
You got stuck on oneplus boot up screen. (this was going to happen because of the same flashing error at your end).
You were unable to boot back to nougat as well because of the same issue.. Never flash the recovery as system. This won't let you boot the device.
To restore your nandroid backup just follow the steps below
As you confirmed you booted to stock rom with a stock recovery.
Flash nougat twrp via fastboot
Boot back to the twrp recovery and restore the nandroid backup and you are good to go

I'll make a video in my free time to help you guys with the steps that I've followed to flash oreo rom and how i came back to nougat successfully.
Hello @maxs8007
Sorry I didn't have any screen shots of the prompt and finally I was fed up with the whole process and had to switch back to oreo stock rom.
Login prompt I was referring to was standard pin required load android. Black background with only pin entry.
BTW I tried blu twrp recovery oreo version and nougat version.
What's interesting is, after several failed attempts it said I got 10 more tries before phone wiped out but after 10 attempts it started counting backwards from zero, - 1,-2 etc., finally I had to flash stock recovery via fastboot and selected forgot password option which reset my phone.
BTW I have deleted all those files from data/system I found another thread but no dice.
Thank you for trying to help us all.
@maxs8007 followed your steps. Booted to oreo, didn't felt as stable as nougat then booted back to nougat. You saved me. Thanks.

I'm sorry that I was unable to help you. The thing is I never used the pin prompt to load android because I reboot too often to flash things via recovery and its too much of a hassle to enter the pin everytime the device is booted and I think it's too much to a security for a android device when there's already a lock screen present once booted to secure the device.
Please don't put the pin entry to load android next time if you flash stuff regularly. It will save you the hassle of going back to stock rom and recovery when something like this ever happens again. The files which I told you to delete in the image I posted above remove the lock screen protection completely
The login pin at the boot to load android was implemented to avoid unauthorized access to the device in case it gets stolen or lost.

Frankly no clue why deleting those files didn't reset my pins and I even deleted gatekeeper files too.
Maybe these are lock screen key files and android boot prompt stored somewhere else. Not sure though.
my flashing history:
i was on audax (oos based nougat rom) with blu spark kernel before, then went to official ob1, then back to audax, then back to stock oos nougat and now i flashed audax and after clean flashing it, it just wont boot up.
when i try to boot up i see the 1+ logo but then it reboots to recovery. i also tried flashing stock nougat again and also flashed stock kernel manually but it also doesnt work.
i always do:
1. wipe system/dalvic/cache/data
2. install ROM
3. wipe dalvik/cache
4. flash magisk (also tried without flashing magisk)
5. reboot
i've been looking on the interwebs all day but nothing worked.. help pls :/
EDIT: problem was blu spark twrp. Maybe installing Oreo ****ed it up. I flashed codeworkx newest twrp universal build and now Im able to boot again!! Btw: I also found that magisk 15.0 prohibits a proper boot up and results in a boot loop. version 15.2, however, does the trick!
when it auto reboot to recovery, formate data
When s**t happens, it is wise to start everything from scratch:
-boot in fastboot mode and flash stock recovery with "fastboot flash recovery recovery.img" (rename recovery.img with your recovery filename), then reboot recovery and select english, advanced, adb sideload;
-flash stock OS with "adb sideload rom.zip" (rename rom.zip with your Oxygen OS filename).
Procedure will require some minute because of the large file size. Remember to save all your data on internal storage first!
I advice you to flash original recovery because often sideloading in TWRP leads to some error.
Your phone will boot again... after that you may reflash TWRP, Magisk etc
I had the same issue. Bootloop and jumb into recovery by itself. You have to flash magisk 15.2 via recovery and will be boot.

He says that it occurs even without Magisk... I had a similar trouble once, and the only way to solve it was the procedure I wrote above...
I dont know if you can boot it w/o root
