It is stuck in recovery mode. Your drive is still good. Ms28 drives are hard to mess up.
I had it happened to me by not using the right mtkflash comand one night when i was tired. It went to constant blinking green on the front of the 360 even though it booted to the dash.
Now all you have to do is to use dosflash (automode) instead of mtkflash in dos.
Make sure when you boot up your pc you have every drive unpluged besides your boot flashdrive.
When booted to dos fully connect your 360 dvd to the computer and turn the 360 on. Then type Dosflash. it will find the drive and ask you what you want to do. Commands will be displayed.
Good luck.
Gotta love it when you get a nice clear answer that works. The drive is now back in the land of the living.
For anyone finding this that has the same problem, this is what I did.
* Copied the dosflash16 directory to my bootable USB drive, along with a copy of my original firmware.
* Switched off PC, disconnected all IDE drives (& SATA if you have them, I guess).
* With 360 connected but off, booted with USB.
* Go into dosflash directory (dosfla~1 cos it's DOS), turn on 360, run dosflash.
* dosflash gave me the "MTK Vendor Intro Failed!" error, did I want to retry?
* Select Y to retry, switch off 360, few seconds, back on again. AFter a few seconds, dosflash detected it.
* Followed dosflash instructions to flash original firmware back on.
