Guys, I apologize for this late reply, but unfortunatelly, because I am totally new to smartphones, I am still in trouble. I should probably say that I am actually using a Precedent on Straight Talk, which as far as I know, is the same as the Prevail.
I turned on debugging, unmounted the SD card, and ran the bat file. It gave many "Unable to" errors, but did display "You should have root" message at the end. I then downloaded busybox, but when I attempted to install it (after a reboot), I got a message "Busybox was not allowed root access!", then it suggested making sure that Superuser allows root access. I rebooted the phone and started the process again when the Samsung logo was displaying, but the results where the same.
I have downloaded RootCheck, and it tells me I do not have root after each attempt. Could you please help me with any additional suggestion.
Many thanks in advance.
Infante
