    Thank you for following your tutorial, successfully rooting, and flashing the system

    Hi there, I'm a noob regarding to this, but I was able to follow this guide successfully for my A225m.

    But I'd like to understand what's going on here, can you give an explanation about each step and what does it do?

    Also, can the vbmeta flashing be done _without_ Odin? For example using only fastboot (which works on Linux unlike Odin).
    https://android.googlesource.com/platform/external/avb/+/master/README.md this is documentation about vbmeta

    i think it cant be flashed without odin before twrp is installed

    Caos Worked fast here but some stuffs did not, like Digital Fingerprint, USB file sharing (just on recovery mode) and the cameras do not count, due to a problem on them, so I can't say if it worked or not.

    Wireless worked on 2.4 and 5.8 GHz

    Dual Sim+SD card worked fine, all at the same time.

    Now I am goint to try another rom... this time will be the "lineage-19.1-20220410-UNOFFICIAL-arm64_bvS.img".... Let's see what will happen...
    a melhor GSI é a Pixel Experience...funciona super fluida ..mas tem os mesmos bugs
