youll need to remove PG98IMG from your sd card so you can get to recovery. you can then restore a backup.
to edit the android info document,youll have to find it in the rom download. it will be inside a PH98IMG file inside a file named "kernel"
unzip the PH98IMG,and open the androind info text document. you should see something like this:
modelid: PH9810000
cidnum: VZW__001
mainver: 1.02.605.6
hbootpreupdate:12
youll need to edit the mainver number to match whatever you have. with ICS it should be either 3.10.605.7 or 3.10.605.13
main ver of android info document
cannot be lower than the main version of your phone,or youll get the main version error.
you can find out what your main version is by putting the phone in fastboot,open a command window,and type:
fastboot getvar all
youll get this output(this is a sensation,but you get the idea
):
Code:
c:\mini-adb_vigor>fastboot getvar all
