hlp with custom firmware

Alright from what ive come to find out i need Grand theft auto-LCS to downgrade a 3.0 firmware to 1.5 then install a custom firmware. But dose the custom firmware have all of the current updates?

Custom firmware has the same functions as the regular updated firmwares plus more. So yes you'll still be able to do everything the you can do on the regular firmwares.

Well you don't have the full update from 3.80 with the PS3 thing, but soon there is going to be a 3.80 M33 so you will have that too.
