Installing a GSI Image

[LucasDrouot09]

Good morning,

My Galaxy A21s being limited to One UI 4, I cannot have the new features of the Samsung overlay, nor the features of Android 13 and soon 14...
My device is compatible with Treble but each tutorial on this subject is different...

Can you help me ?
Thanks in advance

PS: my device is not rooted and its bootloader is not unlocked.

Lol Badger I was hoping for a answer haaaa , but Mr I see that there is Android 12 for the A21S and that means there is TWRP as well meaning for you to find out if device is AB or A only etc and try GSI's and pray they will work..
