just to clarify. i have a z120bt and want to do the 130bt software. i have already downloaded the SD card torrents and the 2.003 file and the 2.004 hack as well.
should i first update my 120 to the legit real 2.003 from pionerr and then run the 2.004 update or can i just patch the 2.003 folders and run the 2.004 update right away?
