S620 OS is completely hosed

[evan.ingam]

Hi - while trying to install Skype, the entire OS simply crashed. The phone does switches on but no longer finds the OS. Hence, I have no way to get an ActiveSync connection. Is there any way to install a clean O/S onto it?
Thanks in advance,

First step take your time to read the sticky located at the top of forum..

You could try an hard-reset and if all else fails flash stock ROM via bootloader, then update to ROM of choice.

Thanks. I did. Particularly the "unbricking instructions post" from ookba.

The issue is that my Dash does not even start up. Hence, there is no way for me to get an active sync connection.

Current Status:
- phone can be started by pressing the Camera key and Power, which shows the red-green-blue screen
- phone can then be connected to the PC via a USB connection. I hear the ba-bing, but the phone does/will not establish an Active Sync (which makes sense)
- downloaded the TMO official ROM from the TMO site which is a WM6. Now, I know my phone did not previously have WM6. It probably had WM5.x but I cannot find the SHIPPED ROM anywhere.
- when I tried the RRU from TMO WM6 ROM, I got through all the way to upgrading. At which point, the mobile screen went to a white/grey with status bar stuck at 0%. But the PC application crashed and gave an error 300.

repeated the same with Kavana's ROM and the same issue.

I am looking through the forums for error 300 but most solutions seems to require an Active Sync connection. Any other suggestions?

Thanks.

have you tried hard reset? thats your best option

like stylez said, find the stock rom that was already on your phone and flash that.

i know you said you cant find it but it'll be online somewhere

The key here is that you find your original stock rom, I had the same issue a while ago and took some time to get my stock rom in the web, since the forum didn't have it. I found it in the rapidshare library http://rapidlibrary.com/index.php?q=rapidshare+library, searching under HTC s621 rom. Additionally, have u try method # 3 in the unbricking tutorial? It worked for me.
