I've got this model yesterday and I have been trying to find a global rom, the hardware is exactly the same as for the
which has a global rom, so probably it works for the P11 too.
Another confusing thing mentioned here is the support for the pen, last year's model which is also called the Tab P11 Pro works with the version 2 of the pen so be careful when ordering as it's easy to make that mistake. This model is supposed to work with version 3 (I don't know if you can still use version 2 tho)
* Except for the back cameras as far as I have been able to check.
** The link provided is for a store that sells the Xiaoxin Tab P12 Pro with a global rom as proof nothing else is intended.
