What is included on the SD card?
Is the hacks.ini file the only file necessary to put on the SD card in order to update it after I loaded priiloader already?
Are there any other files I must include on the SD card when I use the SD card for the first time?
My prior install with an SDHC card enabled me to get as far as the Priiloader install without a problem.
What extactly do you mean by update? The files you will need to soft mod are all included in the tutorial so im not sure what your after.
