Go to settings; about phone; software information; baseband version
Mine is A205YNDVU4ATA1
So I have a U4 bootloader
If it was the wrong TWRP it wouldn't work at all
Can you backup boot;data;system and then restore the system?
I try to flash to enable camera 2 api. The zip i download from this page:
cyanogenmods. org/enable-camera2-api-install-gcam
I cant install Google Play mod from lucky patcher too, it's only work when i flash Magisk Manager
Wrong TWRP. Go here

4steps
Installation Instructions.
There is never only one way to do anything. The following steps have worked for me.
Before you start, make sure you have rooted the A20
https://forum.xda-developers.com/android/development/root-samsung-galaxy-a20-rooting-guide-t3954872
This part may not be necessary if you're recovering from a crash.
To install TWRP
1. Download the U2 custom recovery from here
https://androidfilehost.com/?fid=1899786940962574261
2. On the PC rename the unpatched recovery as recovery.img
3. Use 7zip to make it into recovery.tar
(right click and choose add to archive)
4. Use 7zip to add your patched boot.img to recovery.tar
(right click and choose add to archive and choose recovery.tar)
5. Download vbmeta.tar from here (https://forum.xda-developers.com/showpost.php?p=80188834&postcount=237) and extract vbmeta.img
6. Use 7zip to add vbmeta.img to recovery.tar
(right click and choose add to archive and choose recovery.tar)
7. Install recovery.tar to ap slot using Odin.
If you are getting messages about being unable to flash the recovery try this.

8. Boot the A20 into TWRP and mount everything that you can.
9. Format Data (not just wipe) - this will remove the encryption of the data partition.
10. Flash this zip View attachment Disable_Dm-Verity_ForceEncrypt_08.18.2019.zip
11. Reboot into Recovery. It may reboot into download mode. If it goes to TWRP skip step 12. If you already have a backup, you can go to step 16.
12. On the pc install recovery.tar to ap slot using Odin.
13. Reboot phone and re-enter all data.
14. Reboot into Recovery.
15. Backup only 3 parts: boot, data & system (not system image)
16. You can now restore boot, data & system from TWRP after any crash, but you may need to forget your wifi and go back in to it.
You can now move on to installing a new GSI ROM .
It you get stuck you can come back to Samsung by using your backup.
GSI ROMs are here.
