Jasp some features in kitchen needs update script like adding root permission, busy box and for adding init.d support and all so convert it to update script (Amend)....

finally after finishing with you work before compiling Rom change back to updater script (edify) and check for mountpoints and ui prints if it's correct then compile, sign and flash definitely it will work all the best :cool::cool::cool::cool::cool:

Use my meta-inf folder which has no update script so convert it to Amend format first (beginning) and at last convert it to Edify to flash...

Try to come from beginning again definitely it will work follow the steps.

On flashing obey these steps:

Wipe data/factory reset

Wipe cache

Wipe dalvik cache

Format system

Then flash. ;);););););)

Guys here i present another awesome things on our device

External to Internal Memory Swap method

please follow the steps carefully :laugh::laugh::laugh:

- Download and install the app that i attached here

- go to settings:

1.check 'send rescan'

2. check 'Use per default'

- press original mounting point and change as 'sdcard0'

- press Ext.sdcard device Access and change the value from 179:49 to 179:33 its our device access value

- press back button and come to main screen

- check 'At Boot' box

- Now press External>Internal*

- wait till u get a small fraction popup message like 'Android sdcard permission granted' something like this

- Now go to storage option in settings there u will see your ext sdcard is swaped as internal sdcard

Use Class 6 or Class 10 Sdcards...I prefer Class 10

Dont worry all your apps data will be swaped to ext sdcard so apps will work normally

:laugh::laugh::laugh:

I swaped my 8gb sdcard as internal memory:
