Thanks for you're reply.
Ive done exactly as it says.
I think step 5 is when u have rebooted the devise thou ive done that but it just boots up normal and i dont see any flash gordon app comming up at start !
1. Root your device
2. Install modified Flash Gordon app (no busybox installation needed)
3. Download this recovery to SDcard
4. Launch the app and allow it root access
5. Tap "select zip", find the zip, "flash now"
6. Donīt try to reboot with the app, but do regular reboot in power menu <--------------- Doesent work !!!
In other words you're suggestion does not work for me...
