Thread: How to make a service (cure) firmware for your Garmin unit

Nice. But not always helpful. Sometimes there could be bad sectors in the memory or sometimes nuvi just not want to boot even if you change extension of the files gpi, gpx, img, vpm, jpg, srd,srx, asr, srf, gcd etc. IMHO the best way is changing the drive letters everywhere in the memory. Here how to make it in Hex:

Find and Replace everywhere in the .rgn (boot+fw_main):
30 00 3A 00 2F to 00 00 3A 00 2F
31 00 3A 00 2F to 00 00 3A 00 2F
30 3A 2F to 00 3A 2F
31 3A 2F to 00 3A 2F

Here is such an example:
