I successfully managed to increase the space by flashing android rom on my hi12 8350 with a modified gpt.bin file.
HOWEVER, now the Front camera which was working earlier with the default built is NO longer working.
The thing is when I got the tab my default built showed in Settings > About tablet : 20170327.182659 but when I flashed the rom today the latest android version I could find on Chuwi from posted hackerjac’s thread was dated for 20170317. It is my understanding that although 10 days apart the newest built solves the front camera issue.
So, I need help again please…. I dont need to change the firmware because the same front camera was working an hour back. Hence its the android built’s issue, in fact if chuwi releases their latest android version for hi12 8350 there shouldn’t be any issue.
