Question [Q] Stuck at the t_mobile splash screen

OK. So, I was going to root my wifes Mytouch slide 4g. I have rooted several phones in the past and never had an issue. I got i unlocked, I flashed clockwork, but I couldn't get s-off.

I used unrevoked, but it kept telling me it wouldn't work with the current software/update #.

I went to install CM9, everything seemed to go OK, then it wouldn't start.

Now, I have gone back to the stock images and they act like they are being applied in HBOOT....the status bar starts filling up, etc...but nothing happens. It doesn't ask if I want to apply the update, etc.

I have searched, and searched, and I am out of ideas. I really wanted to root this for her and put a decent ICS ROM on it, but at this point I would be happy simply getting the phone to come back on at all. Please help! Thanks.
