Upgrade Samsung Galaxy A71 to Android 12

[Ahmad_NiceBoy]

Hello,
My Galaxy A71 haven't received Android 12 update, yet!

My PDA : A715XXU3BUB4

But Android 12 official Rom is available for A715FXXS8....

Q1: Can I upgrade to Android 12 with different Rom ?
From binary 3 to 8 !

Q2: If I upgrade manually, Will there be a problem to upgrade to Android 13 in the future?
(According to the last news, A71 will receive Android 13)

Q2: Which Rom do you recommend?
1 part or 4 part?
What region?

And due to the manual upgrade, my phone data will be formatted?

Thanks,
