It depends on Hi10Pro model.People with PQ serial reflash Android with Cyanogen Mod (CM 12 or CM13) with no problem. Here the link to one of the sites.

I am not so lucky, latest model HQ have another touchscreen controller. So I tried to install CM 12 (no Cm13 for HQ64 due to hardware change) , install it, Google finally works but touchscreen orientation ruined everything. Its landscape if you use it in portrait position and portrait in landscape.
And you must be VERY CAREFUL in choosing the packages. First you need to unlock it, next – remove dm protection, after that you can flash CM. There is a very helpful forum but it is in Russian only. So the software package (Flash tool, firmware and no-erase file is a must if you try to flash tablet by yourself.
