Hello I just received my mini 2, the only update available is V01.02.0000, can I make a less recent update like V01.01.0700 ?  I see that several people have problems with the last one.

For the 100th time, it is NOT possible to downgrade firmware on the Mini 2. Just install the latest firmware and enjoy flying your drone around. So MANY paranoid people here getting their pants in a knot about updating. I have updated my firmware and Fly app and my Mini 2 is flying like a dream, no issues at all.
Give it a try, you might BE pleasantly surprised.

thank you i will follow your advice

Hello there. Thank you for reaching out and for these information you have given. DJI would recommend for you to update your DJI Mini 2 for compatibility and reliability purposes on both the said DJI drone and with the DJI fly application. You need to update for you to be able to get all the most updated functions for your DJI Mini 2. Thank you and fly safe always.

with every update I see people with problems on the forum.

I'm flying with the latest firmware and latest Fly version without problems.
A lot of issues were solved with the latest versions.
