I tried and failed at this today before finding this post.
I went by this guide
How To: Root Your HTC Hero in One Click! (Updated 01.10.10!) | The Unlockr
but i hit the "Backup Failed: Could not run command" roadblock which I think is because i have the most recent three firmware but wasnt sure where to get the original firmware from.
Am i right in saying the 1st rom you mentioned is the orignal three firmware, the 2nd is a generic htc firmware and the 3rd is the previous version of the generic htc firmware?
- RUU_Hero_H3G_UK_2.73.771.73_release_signed_NoDrive
- RUU_Hero_HTC_WWE_2.73.405.38_WWE_release_signed_No Driver
- RUU_Hero_HTC_WWE_2.73.405.5_WWE_release_signed_NoD river
Just out of interest, what custom rom have you gone for? a tweaked 1.5 with Sense or stock 2.1 without all the drivers?
Finally, once rooted and the official 2.1 firmware gets released, would i be able to use the latest HTC rom rather than the three version which no doublt will be released months after the generic one?
Cheers
