[Tutorial] How to setup dual boot on MTK

[Manish Pathak]

Bro i have xolo A500S IPS mediatek 6572 device with 512 MBs of ram.
i've tried to dual boot it with color os for xolo A500s IPS.
I've tested both the stock rom (i've downloaded) and color os rom, separately on my device and confirmed if everything is working perfectly or not. And i found it worked like charm to me.

now i was plannning to dual boot my phone with stock rom as primary and color os on sd card

i flashed stock rom in my phone (pre rooted)

then i took out my sdcard of 8Gigs and made 4 partitions as below

5210 MB fat 32 for storage as sdcard
1024 MB etx4 for /system
896 MB ext4 for /data i wont be installing any shit to it, i'll keep no apps
502 MB ext4 for /cache
so final layout of sd is
mmcblk1p2 1024 MB /system
mmcblk1p3 896MB /data
mmcblk1p4 502 MB /cache

and after doing all this i modified the update-script of color os which was meant to be installed on sd card

and i created the custom boot.img by steps mentioned in this post .. and packed it in flashable zip

i put color os + custom boot flashable zip + stock boot flashable zip

now i headed over to cwm and flashed color os and it was successfully flashed to external memory card
then i flashed the custom boot zip to boot color os and when i restarted my phone

my phone stuck on coloros oppo logo.....

and when i want to switch to primary rom i simly go to cwm and flash the stock boot zip and stok rom works fine..




what should i do to get the color os working
