TomTom 730 go stopped working

I tried upgrading my maps think i screwed something up helppppp. When i turn the unit on the startup screen comes on then shuts down right away. I tried resetting with a paper clip nothing happened. When its plugged into the computer on tt home i can access everything on the computer but the tt screen is blank. when i turn on the unit and hold the button down the the bios screen says startup...............sleepmode is the unit in a sleepmode? On the same screen the battery is charged to 4125 i guess the battery is working.One more thing when tt is plugged in the green power light is on when its unplugged no power light is that normal?

As long as you can access your TT using the PC or Home nothing is lost ;)
What Navcore and map are you using?
To get a first start try this :
Delete all files in root of your TT except the file ttgo.bif.
Leave the map folder untouched.
Start Home and update your device until you got the version 8.351 for your Navcore.
If you use genuine maps it will work now, if you use patched maps you'll have to patch the ttsystem/PNDNavigator using FastActivate.

Seems like it does not want to update i deleted all but the folders and ttgo.bif put on tt home and says nothing to update????????

Delete all but the map folder & ttgo.bif file. Reboot before you attempt to update.
