If Nuvi starts you have some hope lol , try Kunix's cure with right HWID
It's a 200 but updater won't accept 0660 ID.
After a couple of tries g7towin says it's ID is 851,tried the firmwares you sent,no luck.Do you have any firmwares earlier than 5.00?That's what's loaded now.
This is no version related.
When you run updater.exe proces go to the end OK and you have message Update OK or updater won't flash or add some error?
In nuvi 200 you enter pre boot like this:
1.) Open updater.exe window and add dot beside USB
2.) Connect nuvi to PC
3.) Pull ON button in left position and hold it there
4.) updater.exe will recognize your unit ID and now press OK button ( you have about 5sec to press OK button)

With your boot sequence i was able to get a little further.On screen message "software missing" to "software loading" a couple of times.Then it goes back to loop,frustrating!
Thanks much,will try!
