Post-mortem Android device decryption

If you ever run into trouble and can't decrypt your phone, but still have the image and password of the encrypted file system, you can use this tool to mount the encrypted file system on your PC.
My i9300 display and touchscreen broke, but I managed to dump /dev/block/mmcblk0p12 via recovery. This partition contains the encrypted /data file system on my device.
So I took the AOSP code and wrapped a small command line tool around it to decrypt and mount the device on Linux.
I hope this is useful and that this is the right forum for such things.

0. Install AOSP based rom like LOS
1. Boot to twrp, conect a pc.
2. Run "adb pull /system/vendor/ * ./vendor"
3. Extract boot.img from zip intaller
3. Extract ramdisk from recovery.img and boot.img
4. Modify the fstab files on both ramdisks:
- Change mount poit from "/OEM" to "/Vendor"
- or add the entry coping the line of /system,
(remember that "/by-name/" your partition is "oem")
5. Check for init.rc if have a line called "#mount /system/vendor for devices...", And coment with # the syslink line
6. Flash the moded recovery and boot and look at "mount" in the new recovery If vendor is here and mount it
7. Run "adb push ./vendor/* /vendor/
8. If the rom boot is near yo he treble...., Modify build.prop and fin "ro.treble.enabled" and ser to "true"
Now treble check Will said that you have "treble support" but you can boot GSI because need more fixes, that is all that i know i'm in the same problem with my SM-A720F

How to enable Camera2API on Redmi Note 5 AI without root for Google Camera?

Hi
I know there may have been numerous threads on here and various websites setting out how to enable camera2API without root on Redmi Note 5 AI, however, I am struggling to get this installed to enable me to ultimately get the Google Camera app.
I have followed through the steps on this particular website (https://www.technobuzz.net/google-camera-redmi-note-5-pro/) to enable the camera2api and all seems to go well until I get to the step before 'adb shell' where nothing really happens. I have tried so many times and each time the result is the same. I am not sure where I have gone wrong. I have already had the phone unlocked from Xiaomi. I hope someone on here would be able to help me out on this.

Any help would be greatly appreciated.

persist.camera.HAL3.enabled=1
persist.camera.eis.enabled=1
Save build.prop file and copy updated buildprop file to /system/ file

Installing ROM failed "Antirollback check error"

I'm trying to install the lastest room on my xiaomi redmi note 8 pro GLOBAL.
so when I go and check the current rollback version on my phone I get this.
Command: fastboot getvar anti
Ouput: anti: 1
The latest room available in the xiaomi page is V11.0.5.0.QGGMIXM when cheking the rollback version on the room I get this (go to the folder then open in a text editor flash_all.bat).
CURRENT_ANTI_VER=0
So I'm not able to flash the room via mi flash tool. I get this error
Current device antirollback version is greater than this pakcage
Where can I get the correct room?
PD: I'm stucked in a bootloop so re installing a stock room is the only option to save my phone.

This error happens because the folder path has become too long. Copy the folder to the root of the disk and delete the folder name after the model and variant of the rom. Leave something like that. Local disk D - rom PGGEUXM and the files are already inside this folder. Do not modify anything. Just extract the files from the fastboot rom and place them in a folder where the folder path is as short as possible. Hug (sorry for my English. Because I used the translator.

Thanks!, after cheking all over internet found that as you said this is the actual issue, I placed the room folder in C:// and mi flash tool as well and managed to flash the room.
I got this error during the flashing
error:Not catch checkpoint (\$fastboot -s .* lock),flash is not done
But as I read this error means nothing since my actual phone is working now. Hope this can help others.
