Help needed for Dell Inspiron 3521

[casstifer]

So I am installing mavericks on my friend's Dell Inspiron 3521. I am stuck at "considerRebuildOfPrelinkedKerbel prebuikd rebuild has expired" which comes after "**** [IOBluetoothHCIController][SearchForTransportEventTimeOutHandler] -- Missing Bluetooth Controller Transport!"
I read some forum post that this is caused due to Graphics kexts. So I moved all the Intel hd graphics kext to a "Intel_back" folder by booting using "-s". This allowed me to boot and then I messed up by editing the "com.chameleon.plist" using chameleons wizard. I checked the "1366x768x32". Now I cannot boot. I have no idea. I tried -v, -x, -f, dart=0, GraphicsEnabler=No.

Specs:-
Core i3 3217U
Intel HD4000/AMD Raedon 7670M
8GB DDR3 1600MHz RAM.

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx). For a laptop, these details are important and affect critical installation procedures.
