Thread: Alternative Nuvis Firmwares

Example for US unit --> JPN

1). Use US boot.bin ., JPN fw_all ., JPN resources / Override hwid to US /check "Replace HWID text strings" (with US hwid)
result :: you will get US hwid within garmindevice.xml :: can flash directly with US firmware. Exactly your nuvi is US unit.

2). Use US boot.bin ., JPN fw_all ., JPN resources /Override hwid to US / uncheck "Replace HWID text strings"
result :: you will get JPN hwid within garmindevice.xml ::
But your nuvi is not JPN. It still be US unit. You can flash directly with US firmware only.

3). Use US boot.bin ., JPN fw_all ., JPN resources / Override hwid to JPN
result :: Nuvi will say "System software Missing" and won't open.
Your Nuvi still be US., you can fix it by flashing with original US firmware.
Not recommented.

4).Use original JPN firmware / override hwid to US and if success. Not recommented.
result :: Still be US unit. !
If fail ., you can fix it by flashing with original US firmware.

5). Use rgn file ( Original JPN firmware without modified - you have to use specific rgn name ) and if success. Not recommented.
result :: Now nuvi is JPN. !!!
