create a new thread for your device issue by clicking "ask question" at the top
in the new thread, attach a screenshot showing the command you sent and the error, also attach a screenshot showing where (what folder) vbmeta is placed

But my stock boot.img doesn’t have the hex string ‘‘2C 76 65 72 69 66 79’’ or the keyword ‘‘verify’’ at all
My device is Samsung SM-A125F, which is still being boot looped for flashing my own TWRP

It is very naive of you to hope that you'll find ‘‘76 65 72 69 66 79’’. Probably, 5-6 years ago it was a working method. Nowadays, as I understand, verity mechanism is implemented on a much more deeper level in the code of boot/recovery.

Found the strings dm-verity in the boot.img, and all them were removed, but i’m still being boot looped somewhy.
With the kernel image no longer having dm-verity keywords, what are the final steps to solve the boot loops for entering my TWRP which has been built and working when boot loops have been solved?
