Right well ive managed to get so far, but now im stuck with an error. Ill list what i did first incase ive done something wrong.
First i formated my SD card and then downloaded
FlashRec.apk
Amon Ra’s Hero Recovery Image
I put these in my SD cards root.
Then downloaded a file manager from the market, went to the SD card and installed FlashRec, opened it and clicked backup recovery image, then typed in the text field /sdcard/recovery-RA-hero-v1.5.2.img and clicked flash custom image.
Then booted up the phone into recovery mode to check it had worked.
And now onto where it goes wrong

the rom im trying to install is Cyan.
So i downloaded the rom, put it on my SD cards root and renamed it to update.zip
Turned the phone off and booted back into recovery mode. Went to Flash Zip from sdcard, then onto SDCARD:update.zip, pressed home to confirm. and then i get the error.
Does anyone have any idea on what im doing wrong?
