Fix Your Storage Problem (Internal+External)
extract the framework-res.apk from your Ported rom
Open the framework-res.apk using 7zip
Then Go to res/xml.......
here you will find storage_list.xml
Just replace the storage_list.xml with your stock rom framework-res.apk
that it close the winrar.... add the framework-res.apk to your ported rom install the rom and enjoy
Note : After Using This Method on Some Rom the internal and external sdcard get swap like internal become external and external become internal.....
to fix this you have to decompile the framework-res.apk using apktool and then edit the storage_list.xml.....
in storage_list.xml ....you have to just rename the sdcard0 and sdcard1 to sdcard1 and sdcard0 vise versa receptively
Another Storage Problem Solved
The SD entry card is wrong. My external SD card is shown as internal and so, every files like cache, temp files etc. where written to external SD card.
So i have change the the vold.fstab in system/etc. and change the this two line from:
dev_mount sdcard /storage/sdcard0 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard1 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host
to :
dev_mount sdcard /storage/sdcard1 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-msdc.0/mmc_host
dev_mount sdcard2 /storage/sdcard0 auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-msdc.1/mmc_host
And now, the cards are correct mounted.
Good Luck
