Thanks for getting back to me.
I don't really understand what you mean by saying that I must have tried to flash the TPT. I just followed these instructions:
"All in One" This option does all these things for you: Checking if the download isnt corrupted, unpacking the downloaded ZIP file, checking if the unpacked files aren't corrupt and checking if the files still match the original.
If you want to do a "All in One" TPT you can check what partition layout you want to use under "Download a TPT". For example you think "Skate v1b" would suit your needs you can go back to "All in One" and select that option.
When this is downloaded and verified you can start the TPT several ways "Start TPT" to start the TPT. Or power off, remove the battery, put it back in and start the phone with "Power + menu + volum up" all held at once. Or if you are at stock ROM under settings "about phone > update from SD card"
When your TPT is complete, it will reboot into Clockworkmod 188.8.131.52 from here you can install a ROM. (Part 6) Once your ROM is installed delete the "image" folder from your SD so you dont acidentally flash it afterwards.
Anyway, as the only thing that I can load up on my phone now is ClockworkMod, I've downloaded the file from the link in Option 2 on this page:
The zip file has the following files/folders in it:
Do I have to do anything with the checksum that is mentioned on the above page? I can't find a .md5 file within the zip file, but then again, I don't know if there should be one or not.
