Hi panoshm, thanks for sharing your experience. I would be grateful if you could share with us the steps you have tried.
I am glad I can get help/advice from this community.
People of gpspower.net are really helpful and they "work" on Sat and Sun (Garmin staff don't) :P
I wrote to kunix last night and I am still waiting for a reply, hopefully kunix could give me a hint to "unbrick" my "nuvi brick"
To Neil and Catymag,
I don't know where the idea comes from, but it's good to ask / try, who knows it might work.
This crazy idea hit me after trying the steps mentioned above, and I know there is still a method from kunix mentioned by Neil "method of modding ldr.bin and flashing via Updater.exe" which I am not familiar with.
The idea is dismantling the device and get the internal storage device out, connect it to a pc and format it.
Do you think it's workable?
