Help me please ....

[Guest Nightowl17]

Hello, ( sorry for my bad English ..)

I've got a Desire, this is an Orange ROM Desire, I replaced the ROM by an official (method with MoDaCo Goldcard).

Desire was then 1.15.405.4.

Shortly after, the phone made an update over the air, and it was 1.21.405.2; up there, no problem.

I wanted to try running in a Ruu 1.15.405.4 to check if I could replace the previous ROM (for a complicated story...), impossible. So I tried to find another official ROM on the net, and I I put a mistakenly 1.22.771.1, which has a Hboot 0.80. (Found here http://forum.xda-developers.com/showthread.php?t=695667)

This ROM seems dedicated to another country and does not work on my desire (GSM network ok but no 3g ..)

I tried several Ruu -> without success I have always an error bootloader140.

Basically I'm stuck, I panic and I do not know how to restore a ROM on the device.

Is there anyone can help me ?

Thank you in advance for your advice.
