How to do a Nandroid backup on Android 12?

[Flecto]

I have a OnePlus 9 Pro and I'm considering upgrading to Android 12. However, I know that TWRP does not support Android 12 yet. So if I upgrade to Android 12, how could I perform a Nandroid backup of my phone after the upgrade if I can't use TWRP? Other custom recoveries I found are all based on TWRP, so they wouldn't support A12 yet either, I suppose.

Thanks!

I've been searching same. A very long workaround i do is use Swiftbackup to backup my app+data and make a full copy of my internal storage in computer's hdd.

If your phone's current Android is rooted then you may do the NANDroid backup by means of a batchscript what utilizes ADB and is applying shell command dd.

Cool! Where could I find said script?
