[Q] flash original firmware topic

i flashed some builds on my galaxy tab 2 10.1 but im not satisfied with them
all off them seem to be buggy and many builds my microphone is not working

i bought by tablet in belgium but samsung never supplied any updates for the belgian tablet GT-P5110
but i would like to flash original firmware but the lastest version

can i download and install the firmware 4.2.2 from the netherlands from sammobile ?

or will this brick my tablet because of the region change

thanks in advance
