I bought a used Transformer Pad TF300T off Craigslist and it was already unlocked and rooted with ClockworkMod and CyanogenMod. Well, I have no use for all that, so I wanted to reflash to the most current stock firmware. Well, I downloaded the absolutely wrong firmware with the wrong SKU (JP and I live in US) and now I have a Japanese tablet. :/
After much work, I finally got it re-rooted with ClockworkMod v184.108.40.206 so I can install zip from sd card. However, any US or WW SKU firmware I try to install, after the install is complete and I reboot, right underneath the "The device is unlocked" text is "Signature mismatch" in red text.
I tried to install CM 9 & 10 to see if that would help, and it appears to install but it goes from loading 1% to 100% in about a second, and then gets stuck at the ASUS screen.
So, is there anyway someone can guide me? I'm sure I've done some stuff bass ackwards, but I'm only intermediate at hacking and modding, so help is appreciated. I've been scouring forums for weeks, so I give. Help please?
