Well, I don't really know ( exact number ) how many ROMS were made for the Prevail, I just used and tested a few..... It's always personal preferences..... But the most used ones are ( in no particular order ) : CTMod3.80, CM7, 187Mod, Halfass
CTMod3.80 in DATA mode runs great on my Prevail and I have no issues at all..... Some people use CTMod3.80 with SSM mode, they say it's faster..... My important observation is, whatever you use for a ROM, you should have a fast sd-card, like a 16 or 32 GB class 10 card..... However, some cards work great on the comp and other devices, but not in the Prevail..... I usually always use Sandisk cards and never had a problem with them....,,. Once you have , lets say a 16GB class10 card, get Kouma's SDParter app and partition your card INSIDE the phone like ( approx. ) : 13GB FAT / 1GB sd-ext / 1GB sd-ext / 1GB swap
With this partitioning, you can use almost every ROM as well as DATA and SSM mode to try out !!
Hope this helps !
Now you have something to do with your "lots of free time", until Skater comes and answers your querstions !
