Ditto!!!

Hey guys I am having the exact same issue, luckily for me it is my Mrs who done her phone in and not mine :D. She has the HTC Desire 320, I believe she tried to root it on her own without even asking for advice, I think she used the app Kingo Root, she said she went to remove the root but when she uninstalled the app it didn't remove it. (LOL I told her well perhaps that's because there will be some way of removing it, aside from just uninstalling the app), anyway she proceeded not to care and carried on using her phone as normal for maybe a week or two at most, then about midnight one night, came down and said to me,

I was like nice so basically you F***ed it!!!!, and for about 2 weeks now I have been endlessly reading post after post, forum after forum, trying rom after rom, RUU, all kinds of things.

Here is the situation, the phone will boot as far as the HTC logo, it will get stuck in a short loop and reset itself 4/5 times repeating the HTC logo, eventually it will end up at the dead android pic (the android on his back with the red exclaimation mark triangle) with the words 'no command'. From here I can press the power button once to get a list/menu of items (What I assume to be the recovery menu). I can backup data, I can restore the backed up data (both of which do nothing as I guess there is nothing really to back up), There is an option to restore from sd card (which I have tried numerous roms and to no avail have any been successful), I can erase the cache and I can also erase everything and recover, the erase side works fine, I did notice in each of these menu that if you press volume up to activate them and then press the power button once, then the writing dissapears and the android proceeds to have his moving atom type thing in his belly, saying 'erasing..', however even with them completed successfully, it still does not restore.

NOTE!!! If you choose the erase and restore method, once activated with volume up, press the power button to get the spinning atom and erasing... message, when this finishes the phone will reboot, it goes to the htc logo, resets itself, goes to the logo again and then just stays at a black screen (almost like a frozen state, I left it for quite some time and it never changed).

I should also note, which I didn't to begin with, but no matter how long I hold the volume down and power button, there is no such hboot/fast boot menu at all, if you hold the volume down and power button even after it displays the htc logo, the phone just proceeds to endlessly reset and loop through the same process forever.

The only thing I can seem to access with little success, is the ADB CMD prompt through the Android SDK,

adb devices

will indeed return the device (a set of numbers with the word sideload beside it)

adb usb

Apart from the odd fluke, this has seemed to fail everytime with either an error about a protocol or an error stating 'closed'

adb sideload "ROM_FILENAME.ZIP OR .IMG

Occasionally this will throw the protocol error, but generally succeeds and displays the 100% most of the time, however the phone doesn't even try, it just almost instantaniously returns the error message :

[B][I]Installation Aborted (APPLY_ADB_SIDELOAD)[/I][/B]

NOTE!!! That the android lays on his back with this error, but it only says error below not no command.

I am pretty sure that I already came across a solution very similar to the one you posted above, and I just couldn't get it to recognise the phone, the only way the RUU would work, was by completely removing the battery and plugging in the usb, however without the battery in the phone, it just constantly beeps via usb, so I guess it turns on, then off, then on, then off, forever!!! So the RUU fails everytime, if I leave the battery in and try, the RUU program does nothing whatsoever! So I am at a complete loss with it now.

Cheers
