He claimed he made it with a friend
Hmmm
he did?
what happened was that me and @wojtekojtek were working with unrelated things on the a13, and i stumbled upon this twrp so we built it and started fixing the fstab to format data and maybe even decrypt it properly
i dont recall claiming i made it, but if i did thats not the case at all
what we did was fork his work and make some patches to fix(ish, WIP) wiping data in the fstab
its open source tho, we all gotta work together lol.

when he said created he meant built, as thats all we did at the time he made that post.. (now we have made patches tho)
we dont mean to take credit away from the work of others, thats immoral and at the end brings us no benefit
open source means to work together with the work of eachother, not to take the work of others!

So you forked the dt from Edward?
He said he created it with his friend and I wrongly assumed he built it from scratch

yes, we forked it and tried to fix its data (we fixed formatting but not mounting/decrypting, and formatting doesnt work properly anyways)
its still a WIP basically lol
but yeah we didnt create it, we just made some patches for it and built the code

Then please keep names etc as they where if its not stealing work. Or just merge changes. Changing dm-40 to symlinked bootdevice/userdata isn’t much coding.
Encryption and decryption on mediatek Samsung devices can’t be done in fstab. You’ll need the correct services and init.rc to have it working. And i can tell you. That’s hard as no other mtk device has this working.
Only way is formatting data and prevent it from ever being encrypted again, which is pretty much against all Android safety advice.

i know, we didnt want to steal the work, we just wanted to make it work. (dm-40 wasnt a directory/symlink for us)

oh, ive never done anything with mediatek devices so i honestly dont know

thats why we were modifying fstab in the first place, since wiping data wasnt working correctly (dm-40 is not a directory on his device), so we're trying to make it work for his model..
its honestly better than nothing and its not like we have any adversaries or important data to hide, at least not on a mediatek device..

Look at the screenshot.
If you remove the name of the original author then that's stealing!

hello first of all
Thanks to you developers, I think we will install twrp on our A137F.
Thanks for this.

Here, the language that the software developers understand is spoken.
I couldn't follow much, naturally, what is the latest situation?

Can twrp be installed for A137F?
If not, I'd appreciate it if you let me know here when it's ready.

I have magisk on my phone, I've been waiting for twrp for months, good news.

yes, TWRP can be installed on a137f but its little bugged
remember if you want to (for example) wipe data, then you must reflash stock recovery. Report any bugs to @edward0181 <---

Been doing quite some work on this bloody MTK phones.

Have twrp working, with some downsides.
Encryption / decrypt of /userdata isn't working (WIP).
If you'll format data encryption is gone... once rebooted to Android it'll automatic re-encrypt. If using external SD card, it'll be ok.

Touchscreen is a big woobly, need time to construct correct kernel for touchscreen. There is a timeout setting of 2 mins... Not really an issue for normal work.

Will post asap
