Do you know if TWRP would be updated to G6? im not asking for a time frame, just wondering if it will ever happen?
I have A20F SN-A205F baseband A205FDD6S6ASL4
Twrp does install but sometimes I get error messages after flashing stuff like
"Won't install only boot offical binaries"
When I try to restore from a backup the phone boots up but sticks at the Samsung logo. Tried wiping cache/divek and factory reset and nothing.
Again just asking not looking for an ETA

Have you rooted it yet?

Seems like you may not have completed the installation of TWRP.
Can you backup boot, data, system?

I was using the U3 recovery.tar instead of the U4
Choose the correct one for your firmware from here https://forum.xda-developers.com/galaxy-a20/how-to/guide-quick-root-twrp-galaxy-a20-t4069423
Edit: I thought was working but it stopped again.
Very frustrating,

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.
Code:* Your warranty is now void. * I am not responsible for bricked devices, dead SD cards, thermonuclear war, or your getting fired because the alarm app failed. * Please do some research if you have any concerns about features included in this Recovery * before flashing it! YOU are choosing to make these modifications * If you point the finger at me for messing your device. i will laugh at you
Special Notes:*
1. DON'T FORGET TO ENABLE "OEM UNLOCK" (located in Developers options).
2. KNOX will be tripped once you flashed custom binaries to your phone.*
(Your warranty may be voided. However this may not affect you if your country forces Samsung to provide hardware warranty regardless of software status.)
3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.
(You can flash custom ROMs if you want to keep the OS up-to-date.)
4. All apps that use KNOX like Samsung pay, Secure Folder and maybe more will no more work.

Make sure you backup boot, data & system (not system image) before you go on to install GSIs
This TWRP was originally designed for Android 9 but works perfectly with Android 10.
It also comes with MTP built-in.1
Fixed.
Magic???
Looking forward to seeing more A20 people with TWRP who can backup and restore. ?11
Im on U4 and it's confirmed that TWRP is working and installing custom kernel as well.
