chinese tablet cpu a13 hang on android logo

a13 kb706 v1.4 2012.10.19 hang on android

i try many files but same

only 2 times set reached main screen

so i decided to change emmc chip from other pcb

chip manufacturer is same (M)

but after change set not power on even not detected on computer

i use this one : 29F64G08CBAAA

and original one is this : 29F32G08CBACAWP

is that compatible or not ?
 
you need to try with different A13 firmwares sir or simply check this FW
HERE
 
but after changing emmc set not detected by pc
 
those chips differs in memory size, you may have issues in memory addressing.

i suggest you place back the original ic or replace it with same part number then flash the device using external sdcard.
