How to backup the stock ROM of a Moto G51??

[Eze!]

Hi, I've a new Moto G51 and I wanna do a backup of the stock ROM (Android 11). How I can do that? In other Moto models I was able to enter in recovery mode and did a full backup in that mode but in the G51 I don't see that option in recovery mode....I'm realley lost.
Thanks for any help

what? I never seen stock recovery that provide option to backup stock ROM.

stock ROM can be downloaded mirrors.lolinet.com (cypfq) just check your current buildno from fastboot or adb.

fastboot getvar ro.build.fingerprint
adb shell getprop ro.build.fingerprint

mmmm.....ok...only through to TWRP....but this cel is new and I'd lose the guarantee unlocking the bootloader....

BTW, "RRYAS31.Q3-56-79-2-3" that same info in config/about in cell

That version does not appear in "https://mirrors.lolinet.com/firmware/motorola"

only the "RRYAS31.Q3-56-79-2-2". I'll wait until the guarantee expires....in the meantime I'm going to cancel any upd to Android 12.

thanks!
