Hello
After rooting my G3, I installed an AOSP-based custom rom via TWRP. Then later on, encrypted the phone (& sdcard).
Recently, decided to install a LG stock-based rom (Clean Rom 2.8), but can't get passed a white screen asking for a password at first boot. This appears to be something to do with encryption? (From what I recall, there's no password to set when encrypting the phone). I factory-wiped, and wiped via advanced options of TWRP before installing this rom, so thought the phone has been decrypted.
After reading around, I tried flashing the latest LineageOS rom, and it worked fine. Notably, the phone indicates it's still encrypted! though the sdcard isn't as I can access it outside of the phone. I read about this problem with some ROMs not being able to boot past a password/white screen, but CM/LineageOS not having this issue.
Anyhow, how do I fully decrypt the LG phone? I've read various advice, but confused (especially about bootloaders).
Any help appreciated.
I dont own the device right now (in the future i wil) but i think i can help u whit that.... (it happened me with other phones)
The thing is if you have encription in the phone the only way to dencrypt the device is format the data partition through twrp THIS WILL ERASE ALL OF YOUR FILES LIKE PHOTOS AND MUSIC PLEASE DO A BACKUP BEFORE TRYING THIS
Boot to twrp, press the wipe button, in the wipe screen you will see a button that say "Format data" (in the top corner above the switch saying "swipe to factory reset") then twrp ask you to type yes, you do it and this will format the data partition erasing the files and the encription....
For the sd is the same but you can do it from a computer if you want or other way
I hope that this can help u
I installed RessurectionRemix and i followed the process i will describe now:
I was on 8.7.5 developer.
Flash MIUI from Mi Flash Tool just click on option Clean All, Let it flash and boot up, after it boots reboot to fastboot since you did only clean all it'll not relock BL.
Then flash twrp in fastboot. Go to wipe> advance> select everything (data, system, cache, dalvik, internal, vendor) everything. And swipe right.
Now keep in mind do not touch the format data option at all.
Now go to reboot menu and reboot to recovery after it boots back to recovery transfer the ROM and other files, flash and reboot system and you'll have 100% encrypted device.
Flash the rom
Flash gapps
After that process everything worked fine and the phone was encrypted. Almost instantly (5-10secs) after I power the phone it asked for password.
But i installed magisk through TWRP and since then it asks for password when the phone boots completely and asks the password just to unlock the lockscreen.
Inside settings it says phone is encrypted but my guess is, that it isn't encrypted.
How can i fix that? What is wrong in the process i followed? What is the correct process?
Thank you!
I guess those steps were for lineage os. For others, you've to format data to disable encryption.
i want to have encryption enabled.
I dont want encryption disabled.
What are you asking exactly?
If you go to
Settings - Security & Privacy - Encryption & Credentials - Under Encryption
Are you been offered the choice to encrypt phone? If your not then it is already encrypted.
Is it requesting a password to boot and also to unlock the device?
If you need password to boot, then you selected that as an option when setting up password.
Can be removed by changing your password to swipe/none and setup your password again.
If TWRP, can not decrypt the device, make sure your using the latest.
Why didn't you post your query in RR thread?

I didnt post in RR because, i tried Aospextended and the same thing happened.
Thank you very much for the solution you gave!! I disabled screen lock,re-enable it with password and now it asks for passwoed on boot and on TWRP.
Thank you again!
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.
