Added on November 14, 2011, 4:04 amComing from a stock ROM.

Is this the correct and best checkROM for me ?

New_XXKI4_CheckROM_RevolutionHD_V2.0.0.zip

my advice for 1st timer of flasing custom rom, additional sd card is a must for you to put all ur essential back up files such as efs, cwm back up file.

we never know what will happen during the flash process.

better late than sorry later.

but then again, its not mandatory to have additional sd card, if you can live with only 16Gb on board memory space to keep all your songs and videos..

P/S: use hktool to create back up for your efs file. this efs contain ur phone details such as imei # etc..

u mean the voltage setting? try setCPU for beginners or voltage controller for expert.

try "Voltage Control". its a better app compared to SetCPU, if you're using Siyah.

Yes.

i don't really understand after rooting will improve anything ? since sgs 2 already have 16gb internal i don't need to install on external memory card and which software is best for rooting ?
