Hi Fredin friend,
I Recently upgraded SM-M215G device to OneUi5.1 (M215GDDS3CWD1-20230522142126) Binary 3 and TWRP (twrp-3-5-2-m21-v3-1-a12-tar)but anything I am flashing is either bootlooping or stuck on Rom Logo, I flashed (Disable_Dm-Verity_ForceEncrypt_03.04.2020.zip) still only Rom Logo showing, how to boot the GSIs? Any help appreciated.

Hi

If you had unencrypted data (if you could see files in internal storage) and flashed the latest stock rom, but you didn't flash encryption/multi disabler before the first boot into OneUI, it will probably cause problems.

So try formatting data and flash encryption/multi disabler (although I believe dm verity disabler also disables encryption by default, but it won't hurt flashing them). Or you can format data and not flash anything to let data stay encrypted, but then you won't be able to use the internal storage in TWRP.

Hi friend Fredin,
Thanks for the reply.
I used (twrp-3-5-2-m21-v3-1-a12-tar) and it is smooth (just like previous Soulr-A11 twrp) but sideload did not work while the other recovery (TWRP.3.7.0_11.-.M215FXXU3CWB1.tar) by Dev Ravindu Deshan works great too but Reboot to Recovery does not work properly all the time, so sometimes instead of Reboot to Recovery the changes happen when manually reboot to recovery using usb cable also sometimes it does not recognise pen drive. Till now I only managed to boot Tuki1.2 and the other Lineage 20 zip had Oplist error 1 issue. Hoping for GSI boot too later. Thanks for recovery

What do you mean by it's not fully unlocked? iirc the toggle stays like that once the bootloader is unlocked.

Hi Friend,
When I had unlocked the bootloader of the same device while it had A11 loaded in it, the oem unlock button was TOTALLY GREYED OUT (I swear I'm not lying), I mean even the toggle button was greyed out but in above picture you can see toggle buttons are Blue color and oem-unlock toggle button is light-blue but not fully greyed out, I didnt relock my bootloader before flashing A13 Stock CWD1 update
Now I cant flash GSI they refuse to boot always stuck on bootlogo.

Don't think there is any in between state. If you can flash stuff, your bootloader is unlocked. If the GSI is not booting, that's some other issue. Try the new AOSP ROMs instead.

Thanks Friend,
It looks like Royna's ROM zips (Lineage 20 & evolution_m21-ota-tq2b.230505.005.a1-06050648-community-unsigned.zip & crDroidAndroid-13.0-20230427-m21-v9.4.zip) not flashing, reason - TWRP error : 1 Assert failed : update_dynamic_partitions(package_extract_file("dynamic_partitions_op_list") and repartition issue even while sideloading. The only one that boots is TukiRom1.2, I havent tried Tuki1.3 yet. I tried Roynas' TWRP files too but after boot to recovery they get stuck, the other TWRP files (TWRP-3.5.2-m21-v3.1-A12.tar & TWRP.3.7.0_11.-.M215FXXU3CWB1.tar) boot and work with some issues though.

Don't think you can use ROMs for A51.

I know the link says A51, but it does have the builds for M21 M31 and maybe a few more inside
