Default Newbie Question - Please Respond

Quote:
Hi,

I am tempted to flash a custom ROM onto my Xperia, but before i do that, i have a couple of questions that i hope someone here might be able to answer.

1. Is there a guide available that explains everything step-by-step? I.e. is flashing of ROM the only thing to do? or are there other tasks required like flashing SPL or something like that? (I literally have no idea what SPL and similar terms mean either)

2. If after having played with a custom ROM, i plan to revert back to the original stock ROM and settings... is that possible?

Best Regards.

Nevermind... I found my answers (i think so!)...

Best regards.
