[ro.build.product]: [rk3066]
[ro.hardware]: [rk30board]

what i wanted to do is change the boot logo in TAB after some reading on forums i came to know that logo which is a PGM format file which is encoded in KERNEL so what i did was readout the kernel after root via ADB

dd if=/dev/block/mtdblock3

I got the kernel image and loaded in RK3XX FIRMWARE TOOL 5.7 in which i can modify the logo correctly but when i write the modded kernel into the tab it does not power up

i do not know what i am missing
