I created a WORKING recovery for samsung a137f ! and its working. I have proof

but I have encrypted Data partition and I want to decrypt it...
I can't format data through TWRP ;-;
Great news.
Use stock recovery to format
Method 1.
1. Connect to pc and boot into stock recovery
2. Factory reset
3. Reboot into download mode.
4. flash twrp.tar into the ap slot
5. reboot to recovery from main menu (not just reboot)
be patient- It may take a while
6. Advanced, terminal. Type multidisabler (twice).
7.
Or flash samsung multidisabler zip
Or, for older phones flash dmverity zip
8. Reboot to recovery from main menu (not just reboot)
Backup boot, data, super and dtbo
9. Reboot to system

Would have been nice if people just asked if it’s ok.
But anyway, above solution would work. Still building it up with decryption working. Need the correct libs and init files configs.
Hello :D
when will new version release? and can you compile it yourself and add to releases? and.... why you had error in fstab to mount userdata? lol
if you want, I can test it / or help you with sth (I have a137f phone)

edit: I can now wipe data but I can't boot into OS after this, it show an Android Rescue party trigger

reason is fs_mgr_mount_all

Had bigger challenges then that hihi.
My biggest issue is the touchscreen not working on my kernel version. To mount data correctly isn’t an issue. Getting it to decrypt on these stupid mtk devices is….

Will push it once done. It’ll take me some time.

    hey, how to change from 32 bit to 64 bit?
    Like other brand XIaomi has 32 bit architecture, but there are so many custom rom like Lineage os which has provided with 64bit architecture that we can easily install any 64bit apps on it,, Samsung brand especially A13 is not really famous and it has refreshed shipped with Mediatek Helio G80 is far capable to run 64bit apps compared to Exynos 850,,, it really sucks just in a few months they replaced it with better cpu performance.

    this kernel helps to get more speed on A13? and about rom's? i search for costum roms for A13 and i dont found anything, do you guys know?
    Yes it will give you better performance.
    Debloated stock is best
