ii tried altering json files on my pc and it worked i also used a program that doesnt let any other programs know that you have been in them if thy have hack detection but marco cheat did work! i wasnt able to alter prestige but i was able to change the strength of the unit!!!! so props to ya! for some reason this wont work on my tablet!!!!! ill have to figure out why but enjoy all!!!!!!! and thanks marco!!!!

yea i tried that as soon as you alter any code the game sets you to the very first senario in campaign mode as if your just starting! Ive tried many times on my tablet i got half way thu it and then i got stuck i alter one unit from 4 and made it a 10 and bam game didnt play and when i checked the game reset to start i lost all my progress! So i wouldnt advise to alter the json files!!!!
