[Q] LGP715 not--> charing, turning on, connecting to pc for emergency mode topic

I USE LGP715 AND ITS ROOTED
I WANT TO PARTITION MY SD CARD WITHOUT PC SO I FOLLOW A STEP ON YOUTUBE ON HOW TO PARTITION IN SD CARD WITHOUT PC.. TITLE IS (Partition SD card (INCREASE INTERNAL MEMORY)) IT HAS A BLOGSPOT ON THE DESCRIPTION... I DOWNLOAD AND INSTALLED (skin1980-GT-S5360 CWM) AND USE ClockWorkMods's "INSTALL AND RESTART TO RECOVERY MODE" AND THEN THE PHONE GOES TO RECOVERY MODE AND THEN I FOLLOW THE STEPS ABOVE AND LASTLY WHEN I CHOOSE "REBOOT RECOVERY" MY PHONE RESTART -> THEN IT GOES TO LG LOGO --> THEN LOGO DISAPPEARS --> BUT THE SCREEN LIGHT IS ON(screen light is on in 5 minutes) SO I THOUGHT NOTHING GONNA HAPPEN SO I REMOVE BATTERY AND TRY TO RESTART IT BUT THEN IN NEVER TURN ON... AND NOW I CONNECT IT ON LAPTOP TO USE EMERGENCY MODE BUT LAPTOP CANT READ IT (driver not found)... WHY?
