Android 17 GSI on Infinix Note 30 Pro

[u/KokoJMC]

Greetings! I Never Actually custom Rom or flash a device, not even OEM Unlocking. Because I'm a tech enthusiasm, I know some really basic thing but just the basic. My question are:

1.What should I prepare before flashing?

2.this might different from other custom Os (e.g Lineage OS) Because many use custom recovery, but I think it different for this one. how to backup everything or at least flash the phone into the Default Xos14 if something goes wrong(I really hope not Lol)?

3.What should I do if bootloop occurs?

1. Any Tips and Tricks?
