I tried to install treble RR and lineage 15.1 on j4+ but Phone didn't open and reboot to recovery Is there password samsung add in img like vendor efs hidden to make data mounted but corrupted
I use format data and install magisk but all in vain still reboot to recovery and system didn't open .
I made TWRP backup of the most possible partitions if someone need it.
Backup of Stock ROM LDN-L21C432B139 (8.0.0.139)
Also made partition images of stock via DD command via ADB, or FF-ddumper app.
Since /data is encrypted, can not be backed up in current TWRP.
Data EMMC image (with internal sd) can be backed up via TWRP via DD/TWRP to SD/PC/USB-OTG with filesize about 25 GB.

Changes from original: Permissive /Kernel by @EzzUsesAndroid (repacked to 142), Magisk-patched /Ramdisk, Custom recovery, Removed DM-Verify + FileEncryption from /Vendor, Replaced bootanimation to walking fingers in /Product.
After restore, reboot to RECOVERY, not to system, and Data have to be formated! <--- This will remove encryption and set partition to encryptable=footer, so in the future you can backup and /Data (without internal storage). Since it is encryptable, Magisk Manager will shows turned on "Forced encryption" but it is not. You can encrypt it later (but I don't know how).
TWRP backup folder of main partitions: https://mega.nz/#F!ZgQxlSDD!s4eAEun2bC4MrIRL3mcgRA
If you want to keep encryption, flash this, after restore, (before reboot to twrp), but DO NOT format /data, just wipe.
If you just want to remove encryption for any rom, flash this, after restore, before reboot to twrp and format /data.
If you wipe/format data to remove encryption or use custom rom, flash /data/hm_init backup via TWRP: mega.nz
SE Linux permissive kernel by Ezz, needed for custom roms: this post
I have a question, when I want to go back to stock rom (currently running AOSP 9.0 GSI), do I only need to restore the two system.ext4 in the TWRP backup folder?

Yes - you had to restore system.ext4 (splitted in 2 files), but also to format /Data and /Cache and restore backed apps/data later, after stock system successful boot.
If you had already remove "verity" and "fileencryption..." flags from /vendor/etc/fstab.qcom and recovery.fstab, I guess you only need to wipe /Data and /Cache, after restoring /System.
And you need to match stock rom versions in /system as in /kernel as in /version.
I made TWRP backup of stock 8.0.0.142 (feb-2019) with no verify, no forced encryption, with permissive kernel. You can use that or extract images from update.app.
stock rom in 3 files.
Update 1:
I saw that there is newer version 8.0.0.143 (march-2019) for LDN-L21B model, eu firmware C432. No need to restore /data/hw_init folder, just flash
update_data_full_public.zip and update_full_LDN-L21B_hw_eu.zip, ignore error 7 etc, works fine.

Hello. For Lineage 15/16/17, see this post. In short - you need to flash SE Linux permissive kernel to /kernel, wipe /system, /data and /cache and flash GSI image of custom rom to /system.

LDN-L21B @ mega.nz
I should have expected this but after updating to MIUI 12.5.2, Magisk/root is no longer installed and the Magisk App only offers the option to "Select and Patch a File" , which I understand requires a full wipe and I don't want to do that.
Orangefox is also corrupted. I can still boot to it but it doesn't prompt me for my encryption code, so it can't access the data partition. Maybe I can just reflash that but can I flash Magisk from there after that to restore root without having to wipe the phone?
So it appears that the problem is MIUI 12.5 (or any MIUI ROMS based on Android 11), prevent decryption working in recovery mode. https://wiki.orangefox.tech/en/guides/encryption
I tried flashing TWRP and that doesn't decrypt the storage and just shows gibberish filenames too.
So, if we can't decrypt in recovery mode, we can't make backups and we can't install Magisk to restore root to make backups with apps like Titanium, what are we supposed to do?
IMPORTANT: /data CANNOT be wiped. Pictures are irreplaceable (I know should have backed up first, but you'll see why I couldn't)
Here's what happened:
Phone had Lineage OS recovery and OS 18.1
Forgot pattern unlock.
Tried to dirty flash Lineage 19.
Reboot
Recovery error: /data is inaccessible
Loaded TWRP to use file manager to delete pattern files.
Reboot
TWRP asking for pattern to decrypt /data/media, unknown
Looked for pattern files, pattern files didn't exist
Deleted lockscreen.db file.
Reboot
TWRP Pattern unlock is gone. now asking for password.
No passwords work, including default_password.
Can't decrypt /data/media/0 by any means.
Cannot pull using ADB without key which is unkown.
Discovered f2fs isn't supported in new TWRP (WTH!?)
Tried downgrading to TWRP 3.1, won't load.
Tried dirty flashing stock ROM, fails
I have tried many variations of recovery, bootloaders and ROMs
The best I can get is TWRP 3.7 with lineage 19 that just hangs on the Loading animation. Let it go for 2 hours, nothing.
Please please help me. My end goal was to get the pictures so I could upgrade to Lineage OS 19.
