I have been trying to flash oxygen os open beta 9 on my oneplus 3
first i tried the official steps mentioned on the oneplus site
I flashed stock oxygen os recovery
but when i boot into recovery mode it asks for a pattern which upon entering does not decrypt
I then flashed official TWRP and tried to flash the full open beta .zip file but it shows this package is for oneplus 3 this is a ""
also if i try to flash the modified TWRP 28 then also it cannot decrypt the phone
I would prefer not to format the phone if at all possible

Hi, I think you should try to format data. Probabby via fastboot, then install TWRP.
Not sure which are the correct commands for the full format, so have a look around or someone else will help.
Otherwise there is the unbrick guide here in the forums to try.
I'm having a similar issue. So any advice would be great. Just updated to most recent unofficial TWRP (having been on a previous version). Now when entering my pin to decrypt it is not accepted. Would prefer not to have to format data.

I believe the decrypt is a known issue with TWRP and OB8/OB9 with F2FS /data partition. I don't think there's a work around at this time without formatting /data and rooting to prevent encryption.

So do you think there would be workaround in future?

Hopefully there will be, but it doesn't look promising right now. @eng.stk is the one that was modding the TWRP, but has since stopped doing TWRP dev.

Do you guy know where to get the stock recovery for openbeta 9? I downloaded somewhere a file recovery_OBT8N.img, but it still shows dm-verity issue.

Fastboot Format system and data
Then fastboot flash stockrecovery
Then boot to system
Sideload rom
Then fastboot boot twrp28
Then wipe data and install superuser in one go

you mean: fastboot erase userdata?
Btw, I just ignore the dm-verity message to enter stock recovery, and do adb sideload openbeta9.zip and when it boots up again, the dm-verity message is no longer there.
I would try to format (erase userdata) data and flash the modded twrp.

Yeah fastboot Format userdata
But since you don't have the dm-verity you can skip the fastboot Format. Boot into the modd twrp and when it asks for password, hit cancel and then format data (you will have to type 'yes').
Then flash SuperSU or superuser in the same session without booting. This will ensure dm-verity doesn't come up again as it will start in enforcing mode, thanks to SuperSU/superuser.
You may be able to flash twrp afterwards but I haven't tried it.
I upgraded a couple months ago from 8.1 to 10. I ended up doing a full wipe ( or so I thought) through TWRP and flashing the 10 image. However, it seems that I somehow screwed up the encryption on my phone. I can boot the phone and put in my PIN to access and use the phone normally, but inputting the same 6 digit and my old pre-10 4 digit PIN into TWRP does not decrypt the phone and allow me to flash things. If I continue in read only mode in TWRP, I can flash but everything in my data partition has jumbled file names.
So my question is: Am I going to need to back everything up and wipe in order to fix this? Can I simply use Magisk to disable Force Encryption then decryp that way while keeping my data intact?
I would prefer using the simplest least painful way possible, but if I have to wipe to fix it then so be it.
Twrp decoding doesn't work for Q .. best to remove lock before entering TWRP
Also try "default_password".
Well I got impatient and ended up screwing up everthing.
Now I'm having trouble getting TWRP installed back on the phone. I have wiped everything, flashed the latest January factory image, booted to TWRP image, but when I attempt to flash the TWRP zip I get "failed to mount /system" and "failed to mount /vendor". If I boot back into the installed TWRP, I am not able to flash any other zips such as Magisk.

Disable your screen lock. Download twrp again to your pc. Put a copy of the twrp.img file on your phone as well. Fastboot into twrp, select instal, select image, go to your twrp.img,.select to install it to Recovery Ramdisk. You'll have to flash custom kernel and magisk again if applicable :good:
Hello! I'm very new to building custom recoveries, and haven't even completed a successful build yet. I have a OnePlus 7T model HD1905 (aka North American model/Global) running OOS 12. I've tried to find guides on how to make a TWRP recovery, but nothing has worked for OOS 12. I am able to extract the OOS 12 stock recovery.img with Payload Dumper, and am able to create a basic TWRP device tree for android 12.1 using the official TWRP 12.1 Github manifest, but I'm not able to find a good guide to create a TWRP-ready device tree from my stock recovery.img I mentioned earlier. I've tried updating to OOS 11, and using the twrp-keep module on the magisk modules github to keep the official TWRP installed. (It support OOS 11, but not OOS 12). I've also tried flashing the unofficial build made by Mauronofrio, but none of the specified methods have worked. Can someone please either make a OOS12-compatible version of TWRP for the OnePlus 7T, or if they can't do that, guide me in a step-by-step process on how to do i myself? Any help would be greatly appreciated.
Oos12 does NOT support twrp nor does A13
I compiled it but i didn't test it with oos12 (fbe) and custom rom a13 (erofs). I hope it will work..

I just flashed it, and it booted successfully! I'll let you know if I can format /data.
Format /data works.
For confirmation, I flashed the .img of the OOS12 version to the recovery partition.

So... upon further inspection, there's an issue with decryption. I can successfully flash the image to the recovery partition, and it boots just fine. When I tap on "Mount", all of the options are unchecked. One of the buttons is called "Decrypt Data". I currently don't have face unlock, fingerprint unlock, password or PIN set up, and it still promts me for a password when I tap on "Decrypt Data". I've tried entering "default_password" and "password" (but without the quotation marks), but neither of them work. Is there a way to solve this? This is on the OOS12 TWRP, btw.

I just tested the non-OOS Android 13 TWRP file, and it has the same issue.
Can u back up all partitions except data? At least that would be helpful

Nope. Even when I de-select Data, and select everything else, it still fails with the "Failed to mount /data" error.
Yeah, I was afraid of that. No one has cracked twrp for oos12 yet

Hi again. As I've mentioned, both TWRP images boot just fine. However, I am unable to mount /data, as when I enter the "Mount" section of TWRP, nothing except the Cache partition is checked. It doesn't ask me for a password upon booting into TWRP, however it DOES ask for one when I tap on the "Decrypt Data" button in the "Mount" section. I've tried entering "default_password" (without the quotation marks), "password" (again, without the quotation marks), and also my password that I set up when I flashed LineageOS 20. I'm curently running LineageOS 20 on the device. I'm able to access USB OTG in TWRP, but I'm not able to flash anything from there. I'm also unable to change boot slots, or backup any partitions. Formatting Data doesn't allow me to access the data partition on rebooting, and the only fix I've been able to find is changing the data partition format from ext4, to ext2, and then back to ext4. This only works temporarily, and only with OxygenOS installed. Even then, after I change the data partition's format like I mentioned above, it resets my data, as is expected. After setting up the device again, and rebooting into TWRP, the /data partition goes back to being un-selected, and I have to repeat the process over again, and once again lose my data. I am unable to carry out the process described while running LineageOS, and its respective TWRP file that you have made. Any help would be greatly appreciated, and if you know the password that TWRP is asking for in the Mount section (when I select "Decrypt Data"), I'd like to know what it is so that I can hopefully get the rest of TWRP to work. Even with these issues, I'd like to give MASSIVE thanks to you, because you were able to do something that my inexperienced self was able to: That is, create a TWRP file that boots, made from the latest custom rom files, and the latest OxygenOS versions' files.

Thank you for testing the builds and for the feedback . I've been on oos11 for a long time, but today I'm going to flash oos12. Because i would need recovery log files to fix errors.
I don't have no time for some fixes, i will try to fix errors whenever possible.
did you not ttry to use the twrp and the twrp installer builds that are on official twrp site for one plus 7t
then how are folks then flashing roms to one plus 7 t devices if there is or isnt a working twrp .

Every ROM comes built-in with its own recovery. So you'll have to flash the ROM via that recovery's ADB Sideload feature.
lets hope you can get a working twrp going for both andrid 12 and 13 .as my one plus 7t is just been put away in my drawer after seeing that one plus has given up on these older devices. when there is a working twrp i would probably want to flash something down the road. my primary driver unfortunately is a samsung S21 plus .

All works until I tried to restore. Then it got stuck at red dot going around in circle. When I tried to go back in twrp again to format data, it won't mount data after that. Ended up having to restore all over using msmtool.
It mounted data fine before I tried to restore the data part, then it messed up decryption of data despite not having a lock code, no fingerprint, no pattern-lock, or lock screen enabled.
