try switching to 3/9 noapp version. it decrypts fine (at least for me) and no annoying app prompt is a nice bonus :)

to install the new twrp just flash the image? is it necessary to install magisk so that it does not lose its root before restarting?:)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] umair9001:
If you are already on unlocked bootloader, flash the recovery image through fastboot mode..that should work just fine..

TWRP 3.1.2. password

Hello together,

I have a OP3 with formerly TWRP 3.1. Today I installed TWRP 3.2.1. and now it asks me for password to decrypt data.

No passwort is is working, even when i remove every password for screenlock.

I also changed screenlock to password 1234 and tried this in TWRP but still there is an error.

Also "standard_password" does not work.

How can I decrypt my data in TWRP without formating files?

Thank you so much

TWRP Error

Issue solved. While TWRP 3.2.1. was not accepting any password, I just installed TWRP 3.1. again, which took the password and works great.

did a complete reset of the phone, wiped back to official version and recovery, then flashed twrp only and still the same issue, it says" failed to mount /vendor (invalid argument)". [MENTION=3208754]codeworkx[/MENTION] if this doesn't break any functionality, no worries, let me know how can i help further..
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] codeworkx:
Just ignore the message or use official twrp. My variant of twrp supports vendor partition which is used on some custom roms.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] PCWright86:
Is the new update able to restore OOS backup. I know previously it would fail when restoring data. Just wanting to make sure that my backup will work before I go flash a custom rom.

EDIT: Nevermind, I see where you stated to backup system image

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] LoneWanderer_97:
Guys holy hell have i gone through a time with bootloops with this phone and twrp(on oreo at least). Can tell me what EXACTLY i need to do in order to not get the twrp bootloop? Like a permanent fix if there is one.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Skeptico:
What exactly are you trying to do? When is the bootloop happening? We need more info.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] LoneWanderer_97:
Bootloop happens when ever i ever try to flash any 8.0/8.1 rom(custom or not). Ive used both the twrp by codeworkx and blu spark. I follow proper flashing procedures but end with a 5t that just boots to twrp over and over again.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Skeptico:
It could be an encryption problem. Try formatting data and choose yes. Then install ROM and gapps.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] LoneWanderer_97:
Well i actually did try that a few times, i got a custom OOS rom to boot up, but a rebbot to recovery messed that up. If this works how often will i have to do it?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Skeptico:
Well if you decrypt the ROM by flashing the no verity zip each time you flash a ROM, then only once probably.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] LoneWanderer_97:
How about subsequent reboots to recovery? Just flashing things like magisk, etc? Are you on an oreo rom pernsonally?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Skeptico:
Yes. And the only time I've ever had a bootloop issue is when I was on an encrypted ROM and tried to flash a decrypted ROM without flashing the no verity zip.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] LoneWanderer_97:
Mind if ask you to pm me about your personal set up? Rom, gapps, root(if any). Amd flashing instructions?
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] sonicscrewup:
Are you trying to flash Magisk before first boot? That is the only thing I could think of that would do it with every rom.

TWRP not booting

Hi, since last week i always used this recovery to only BOOT in recovery and flash magisk. From the last Open Beta update i can't boot anymore in the TWRP, the phone stuck on the Oneplus logo with the Fastboot mode.

It's only my problem or there are some new form of protection in the oneplus firmware that makes the recovery not working?

Thanks in advance

I just flashed the OOS 5.1.2 which is 8.1. I used bluespark TWRP (3.2.1??) that I installed on the first week of owning this device. Upon flashing the OTA in TWRP, I rebooted then went back into recovery. Found that stock recovery has reinstalled itself. Is there a way to get TWRP back without a PC and ADB?

If I have to use ADB, which TWRP am I to use for 8.1?

Might be unrelated, but now I can't get into developer options. Keeps giving me a "Settings keeps stopping" even after I force stop and clear cache of Settings.

Please read the first few posts of this thread: https://xdaforums.com/oneplus-5t/how-to/soon-oxygenos-beta-1-android-o-oneplus-t3726074

Even though it's for open beta, the same principles apply to updating. If you want to install TWRP again, adb and fastboot are necessary. In order to keep TWRP from being replaced by the stock recovery, you have to flash magisk before rebooting to system.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] duckredbeard:
I still have the twrpbluespark.img file in my device. Can I just reinstall that recovery and restore what I backed up before the update? I am having issues with this post update.

[MENTION=3208754]codeworkx[/MENTION] just FYI.

This recovery works beautiful:

twrp-noapp-3.2.1-0-20180309-codeworkx-dumpling.img

But this newer recovery gives me nothing but issues:

twrp-3.2.1-0-20180414-codeworkx-dumpling.img

The issue is I get rebooted back into TWRP every time I flash a custom ROM.

I can reproduce the issue on demand, 100% of the time.

My usual method is to wipe everything, including internal storage.

Then to "format data". Then flash ROM. And it'll just reboot right back into TWRP instead of boot to the ROM. Does not matter if I flash no-verity or not.

The only way to get it to boot to the ROM is to dirty flash the ROM and then wipe the /data.

But the noapp version of TWRP I mentioned above does not give me these issues. :)

Just letting ya know and sharing my experience in case anyone else runs into the same deal. :)

Thanks for sharing your TWRP with us!
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Spannaa:
Using twrp-noapp-3.2.1-0-20180309-codeworkx-dumpling.img here too - it works for everything I need to do so I haven't tried switching to a newer version.

I had to use stock recovery from beta10 to flash openbeta11 zip, using TWRP always gives me error (unable to mount vendor partition). However, after flashing the OB11 with OB10 recovery, I can flash magisk with twrp-3.2.1-0-20180414-codeworkx-dumpling.img without any issues.

Btw, TWRP 3.2.2-0 just released, but I guess I will need to wait updates from codeworkx to make sure it compatible with treble :)
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] LordDeath:
This just means that your TWRP supports treble enabled ROMs but you didn't habe one installed yet. After flashing the new Open Beta 11 we have a fully formatted filesystem for /vendor and TWRP should not show that warning message anymore.

You probably need to use twrp-3.2.1-0-20180414-codeworkx-dumpling.img for OB11 as it has vendor partition support.

Yes, I flashed OB 11 over OB 10 with Codeworx twrp. Not a single problem. When you flash you will get the vendor error, but after flashing OB11 the error will not appear anymore because you will have a vendor partition.

[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] Spannaa:
Yep, I realise that but thought that maybe an unformatted vendor partition could have been created like it was with Open Beta 10 which would then be formatted and populated on a later release (like it was with Open Beta 11).

I might be completely wrong though...
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] crakerjac:
Running OmniRom and have never installed a O2 Beta. I no longer see warning about vendor partition, so TWRP must not the throwing a code if that partition doesn't exist or is unformatted.

You're right, when I was on OB10 there was indeed a Real vendor partition,but completely empty. TWRP saw it, so did file explorers.

TWRP asking password to decrypt

Hi,

I'm "stuck" with a functional rooted-xposed-OOS5.0.3 OP3 but TWRP won't let me decrypt data.

I downloaded OOS 5.0.4 and tried to flash it the way I usually do (flash new TWRP if a new version is available, flash OOS, install supersu, install xposed). Before that, I always go to Security settings and check "No thanks" at the "Require PIN to boot device" option. If I didn't do that, TWRP would ask for a password to decrypt data and always fail. Loading TWRP without that password is a bit useless since the sdcard partition is empty.

.

This time, I flashed TWRP 3.2.2-0 (via the recovery first, which worked, and then again via the official TWRP app) but it keeps asking for that password. I tried disabling the PIN completely, use a password instead of PIN, downgraded to TWRP 3.2.1-0, but it will always asks for a password just after the TWRP splash screen.

I've tried all solutions suggested on XDA and reddit, apart from deleting the .key and locksettings.db (as I don't understand how it could make TWRP suddenly able to decrypt the sdcard partition), unsuccessfully. I suspect it's linked to Oreo because it's my first OOS flash update attempt since moving to OOS5.0.3. Has anyone been out of a similar situation? Thanks.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] jbd7:
So for anyone interested, here's a solution that worked for me:

- Download Blu Spark TWRP from XDA (twrp-3.2.1-x_blu_spark_v8.61-op3_op3t.img here)

- Flash it to recovery with fastboot flash recovery

At the next reboot, I was able to use all TWRP functions on all partitions. I also noticed that now, even with a lockscreen password and "Require PIN to start device" enabled, that blu_spark version works (it asks for the password to decrypt, and *accepts it*!)

Need help- again...

Solved the earlier issues but now, updated twrp to 3.2.2 (flashed through recovery) to recovery partition

All went well, but when I rebooted into twrp it shows no storage (0mgbts) can't find backups, imgs, zips etc.

Also, facing the crypto root issue where it won't allow me to perform any functions based on encryption (I think?)

Also, when connecting to pc- Windows recognizes the device, but when I try to transfer files it says it cannot perform the task and that the device has been disconnected or (something?)

OP5t running latest Lineage OS

I CAN reboot the system and phone works fine, all data is there.

But need recovery working obviously

Great community, I'm sure somebody can help me with this.

Thanks.

Fixed. Formatted.

Apparently, it has to do with encryption. Would it make sense to remove encryption, try to restore this and then somehow get encryption back on again? (Is that possible without formating the device again?)

Initially, I Installed 3.2.3 codeworkx recovery before trying to flash 5.1.5 OOS, so I couldn't flash the 5.1.5 OOS full zip due to missing vendor.

As a result, I flashed 5.1.4 full zip (as I was on custom rom) then upgraded to 5.1.5 full zip through OOS stock recovery successfully.

After that, I flashed the codeworkx 3.2.3 without issues and got the vendor partition successfully.
[OnePlus 5T  ROMs, Kernels, Recoveries, & Other Dev] gorilla p:
Yeah, from what I understand, the treble rollout was done in two steps. 5.1.4 created vendor partition and 5.1.5 filled it, so you have to flash 5.1.4 before 5.1.5.

What screwed things up I think, was OnePlus releasing an official without treble on between those two releases, breaking that progression.

Yeah formatting was the only way to get it to work for me.

I updated TWRP and now it is a non issue. I suggest downloading the official TWRP Updater App from the Playstore and flash an updated version from the app. You need root though. Latest version of recovery fixed several issues I was having including storage problems.
