[General Questions and Answers] rafik23:
I have a tablet a13 allwiner , it shared like this

nanda (bootloader) :32 Mb

nandc (system partition) :512 Mb

nandd (data partition) :1.2 Gb

nandg recovery :32 MB

nandj (SD card or internal storage): 1.6Gb

i want to modify size to have (like i found it in other firmware for another tablet based a13 cpu)

512 system

512 data

and 2Gb or above for SDcard

i have extract the original firmware with a10 kitchen and change the content of COMMON _SYS_CONFIG000000.hdr and rebuilding

i have change the file for attempting this size like a want and i see in other firwmare

but after rebuilding and flashing the tablet start with black screen( what happen ?)

the original file :

is there any way to do it by flashing it with factory firmware and changing the partitions size ?
