Thread: How to convert 3790us to 3790 Sg/My

"What is cure RGN"
Cure RGN is the modified rgn that modified in specific point for specific cause ... to make nuvi "skip reading" the wrong data inside unit., so unit will boot normally again and let you can delete the wrong file.

What can be a missing file ?
For example :: wrong keyboard (in nuvi1xxx)., wrong custom POIs (in nuvi1xxx) ., wrong .vpm file (flash nuvi to other region)., menu ., modified gupdate.gcd.,wrong map.,

"To locate the wrong file "location" within Nuvi Firmware"
You need Hexeditor to find it out.


Concept :: You need to know what you did wrong ie..wrong map
So you have to find ".img" and ".IMG" in firmware by Hexeditor and then you have to do like this
img -- > mig / IMG --> MIG for all location you find "img" or "IMG"




Now nuvi will don't know .img file anymore., booting will success and you can access mass storage again to delete the wrong file.
