[RECOVERY] TWRP Official/Unofficial v3.6.2 A11/A12 Cheeseburger/Dumpling - 05 Aug 2022

Thanks for the updated twrp, now it can decrypt data in a12.1.

Wow... My respect and congratulations! You finally nailed a working TWRP recovery with decryption for encrypted 12.1 roms. Thank you so much!
Glad that so many guys here around that don't get tired working on stuff for our cheese-dumplings.

I just flashed the latest v5 and was able to succesfully decrypt my 12.1 pin code locked userdata. Didn't have to do the troubleshooting steps of removing the fingerprint & screen lock first, great job on this! Hopefully your work can be upstreamed to the regular twrp as you've done a great job solving the issues with 12.1.

-I have recovery twrp-3.5.0_9-0-cheeseburger_dumpling, can I update via twrp to twrp_op5_op5t_3.6.2_12.1-test-v5.img or do I have to do it via fastboot? p.S My device is decrypted and I currently mount derpfest A12.1

Yes, you can install it by twrp itself, no problem

Just wanted to add another report of success and say thanks! I was waiting to this before updating to 19.1, awesome work. I dirty flashed lineage 19.1 over 18.1 with data encrypted, updated twrp to this build, and it's able to decrypt the data fine.

Just installed Looks good. Is there no way to fix the date and time issue in TWRP? At least I get 2021 here Official still gives me 1970

I believe that forever bug is one we may have to live with.

TWRP is right on time for me

TWRP está na hora certa para mim

Sem When I restart TWRP recovery my setting disappears so my time is wrong. How to fix this?

Time maybe - but check the year when making a backup for example. Some roms have the wrong year in TWRP, like ShapeshiftOS or crDroid up to version 7.17 while now on 7.18 I have the correct year again (at least on TWRP 3.6.2_11, I haven't tried the newer ones yet).

TWRP settings not being saved in A12 version, this has been fixed recently

I'm building a new version with this fix that I plan to post later today.

I didn't forget what you asked, my next step is to check if it's safe to create and restore a nandroid backup on A12.

 

[faoliveira]

OK. Settings will be saved in the new A12 version.
Now they'll only be deleted if you run format data.

I ended up discovering, and solving, a problem in versions A11 and A12 when a backup with encrypted data was performed.
New versions are now available.

I would like to thank again those who are testing and reporting success and bugs that appear

This sounds promising! Thank you for your contributions.

BACKUP/RESTORE

Based on the post:

https://forum.xda-developers.com/t/...ect-8t-kebab-2022-03-09.4302449/post-85292199

Backup:
1 - If you want to perform a nandroid backup select only the partitions: Boot, Data, System image and Vendor image
2 - Make sure USB debugging is enabled on system
3 - If your data is encrypted you DO NOT need to remove your password/pin/pattern first.
4- Copy the backup folder to PC if you will format /data.

Restore:
Remove the current password/pin/pattern on your system before starting the restore process by Settings>Security>Screen lock: Select Swipe (if prompted tap on "Delete")
If you don't do this, the system will not reboot properly after restoring.

This will also remove your data and your lockscreen (encryption) password (you won't be prompted for a password in TWRP or when you restart the system)

In TWRP
1 - Restore: Select the backup you want to restore and wait for it to finish
2 - Remove the SIM card. If you don't do this the system may not boot properly or you may have problems with your SIM card.
3 - Reboot system, making sure the phone is not connected to a PC via cable;
4 -If you find any issues like missing navigation bar or blank screen or something, just do a normal reboot again to system.

Notes:
If you are replacing an Encrypted ROM with a Decrypted ROM, or vice versa you MUST perform a format /data after the restore and you will need to restore at least the data partition one more time.

Dude I'm sorry but I don't want to add mods but you can check with fichl who is expert on this, i don't think there were big changes from A11 to A12. '[THEME][TWRP] TWRP 3.x dark stock theme pack w different colors v4

3 - Reboot system, making sure the phone is not connected to a PC

Erm ... huh? So basically we have to be in Airplane mode when making a backup so we're still offline when restoring it?
And then what - once booted up we disable Airplane mode, insert SIM and reboot again? Or am I totally misunderstnding here lol?

Well, it's an old problem that I honestly don't know if it still happens lol, but after a restore or flashing a new rom, some sim cards may no longer be detected and need to be replaced. I don't use my OP5 as a daily driver so I don't have a SIM in it, when in doubt I think it's better to keep this recommendation.
