To every one facing black screen, please try and install any other costum rom that have init.d suport, and after installing that one, just install this port, I think there is a flaw in the updater script that is not properly installing the boot.img (kernel), if you are in stock rom or coincity you wont be able to boot because coincity uses stock kernel.

I no longer have this phone, so cant fix anything else, sorry for all trouble…


Update 1: Anyone having problems with SU permissions please download SU update above and put in your sd card, reboot to CWM and instal SU update.zip

Update 2: To everyone that have black screen after instalation just download CWM from above and install this recovery, everything should work fine now.


Again I remind: never make wipe factory reset with this rom. You will loose CWM and to restore it just with SP-flashtools.


Not working: Soft reeboot not working.


Partial working: Only one SIM for SMS in default messenger app. go to settings/sim management/and select your SIM card for SMS.

If you need both SMS working,

simply go to playstore and download GO SMS PRO, check dual sim suport mode and it works.

Me for porting it.



1-Enter CWM and make a backup.

2-Wipe Data factory-reset, wipe cache data, enter mounts and storage and format system, go in "Advanced" and wipe Dalvik cache.

3-Install from sd card.

4-When complete, wipe cache data and  go in "Advanced" wipe dalvik cache again, DO not wipe data-Factory Reset! Reboot.

5-First boot may take a few minutes. Mine took about 2 minutes.

6-Enjoy L design and say thanks to the developer and me for porting it hehe…

※Please make a backup of your device before installing or updating ROM
