I have a bricked T95R pro S912 , 2gb ram and 8 gb rom , sinse i couldnt find it's original firmware, after lots of digging i found out that i could flash any S912 firmware as long it has 2gb ram.
on it and they all woeked , i must have tested at least 12 different firmwares from different manufacturers, they all work just fine.
The problem is the wifi , !!! T95R pro is equipped with AP6330 , but none of the firmwares i tried had a working wifi allthough they have the same AP6330 !!! except T95Z plus and T95U pro !
Practically both boxes use the same firmware. what comes to my surprise is that all T95 * firmwares are equipped with multiple wifi drivers !!!
See in the screenshot from T95z plus , it seems to have many more drivers installed compare to the rest of S912 firmwares.
Oh and last thing , T95z plus T5ZP0030 is equipped with a different wifi chipset , so i strongly suggest to NOT upgrade the firmware beyond T5ZP0010.
