Huawei Y7 Prime 2018 (LDN-L21) stock rom TWRP backup

[adeii]

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.

Backup of Stock ROM LDN-L21C432B142 (8.0.0.142)
Before any changes, please backup your /system, /vendor, /kernel, /ramdisk, /recovery_ramdisk for just in case in twrp.
For /data backup online copying of files or Migrate app or Titanium BackUp or something else method.

Extracted from update.app: https://www.androidfilehost.com/?w=files&flid=291939

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).

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?

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.
