1. On phone developer options in settings unlock OEM and enable usb debugging. Connect phone to PC
2. Reboot into download mode by holding down both Vol up and Vol down then press vol up to continue (you may need to long press volume up to unlock the bootloader for some devices)
3. Use Odin to flash recovery.tar into the AP slot.

4. Reboot the A20 into TWRP and mount everything that you can.
5. Format Data (not just wipe) - don't restart
6. Flash View attachment 4975463
7. Wipe both caches and Reboot into Recovery (for Android 10 you will need to flash Magisk 20.4)
8. Reboot system and enter all your data

To reboot into TWRP, hold down"vol up" and "power" during reboot.
Backup boot data and system so you can restore them if you need to.

experience doing this on my sm-a205g (LATAM/ GUATEMALA)
enabled oem unlocking
entered into download mode and was asked to unlock the bootloader
phone got reset / erasing data message
finished setup skipping all stuff, now oem unlock is missing on developers settings (so it worked)
flashed recovery.tar for my android version (11/R) using Odin v3.14
inmediately as PASS! messaged from Odin appeared, I did the vol up + power combo
hurrah! TWRP greets me
did all others steps.
also backed up data and system just in case, then copied the TWRP folder to my pc.

hello, sorry if it is not understood is that I use the google translator
I have an a205g and I already have the bootloader unlocked but when I install Twrp it does not start the system, if it starts in the recovery but after rebooting the system, the screen goes black.
First I tried to install roms but it did not start so beforehand I downloaded a stock rom with the corresponding binary but in the same way I install twrp and it no longer starts the system, I would like to know which twrp I have to install

Can anyone confirm whether the android 11 recovery works on A205F/DS?

Also, is there a way to configure Odin to reboot into recovery after flashing or does that need to be done manually?

Hello friend, thanks for your answer.

I leave you a photo of my phone when it is in download mode, with that information you tell me what I should use then Android 9 U2 Recovery?

Another thing, I am using some drivers in Windows 10 64Bits and nothing connects the phone what will be the correct drivers? Excuse my ignorance and my bad English

Forget it, just change Encrypt to Decrypt...

Did you reboot to recovery by choosing reboot from the menu and then choosing recovery?
