JB VZW 4.2.7 to 4.2.8 - Not a valid IPSW

[bodean]

I've downloaded this IPSW 5 times, from 5 different sites. Using latest sn0wbreeze, 2.7.3.
I keep getting Not a valid IPSW. Any ideas?

If you are using a windows computer. When it downloads it saves it as a zip file. You will need to rename it to ipsw. If you have the name settings so you can see the ending just right click and then rename fro .zip to .ipsw. That is what I needed to do.

iPhone3,3_4.2.8_8E401_Restore.ipsw is the file name that was downloaded.

If you are using a windows computer, go to this location on your computer:
C:\Documents and Settings\<username you use to login to windows>\Application Data\Apple Computer\iTunes\iPhone Software Updates
Remove the ipsw you will see in that folder to another location like your desktop and put in that folder the one made by snowbreeze. Now restore the iOS normally to your phone without the help of snowbreeze.

you dont do it like that, you load sn0wbreeze and then browse for the .ipsw and load it that way otherwise it wont work as you have seen. then at the end you will have created a custom_ipsw that you restore to in itunes, probably would of been easier for you to use redsn0w in the method i showed you but what ever works for you.
