Alternative Nuvis Firmwares

**caputogio** · 7th June 2011, 01:04 PM

Thks for the answers to the second part of my question but I still would like to know what is the main difference between

Japanese version 2.70
Taiwan 3.30:
Philippines version 2.10:
Singapore / Malaysia version 2.80 for 1460

what kind of enhancements will be available if I choose this or that version

Also if I understood correctly if I "Replace HWID text string" of the US for the JPN on my next upgrade it will upgrade as if I had a JPN nuvi correct?

If you use original US boot.bin ., so your nuvi still be US unit.
It means you can not upgrade your nuvi with ogiginal JPN firmware directly.
You have to make a rgn for new JPN firmware again.

(But you still can flash with original US firmware directly)

I don't know about different point of firmwares.

-----------------------------------------------

If your unit is US and you override hwid with JPN hwid and flash., Nuvi will say "System Software Missing" and won't open.

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. !!!

The Nuvi will "read" hwid number from somewhere within fw_all.bin.
For example 1xxx series (CHN fw_all.bin)

3d01d36b42730636aa64f21040aa925c

You will see hwid number 1182.
If you open this fw_all with Hex editor and change this 1182 to 9999.
Result :: Garmindevice.xml will say your nuvi hwid number = 9999.
But your nuvi is not exactly 9999 hwid.

Note ::
you can edit this number without effect in functions.

RGN_Tool will override hwid in other point.(not the same point as nuvi read from fw_all to write into garmindevice.xml)

Garmin read hwid number within garmindevice.xml in term of you use original firmware ( so the hwid number is always right.)

But if you use modified firmware so hwid within garmindevice.xml may be the useless data or incorrect.

You have to see what is hwid of boot.bin. (or use G7toWin to detect the real hwid)

Hi,

I want to upgrade my nuvi 1300 with EU FW 5.8 (modified for JCV and LA - garmin-tutorials/190929-enable-features-your-nuvi-12xx-13xx-14xx-jcv-la-tts.html) by Japan FW.

1) Which number of JPN FW i have to use together with EU FW in RGN Tool?
2) Is it Ok, if I use for wf_all.bin (load from JPN FW) same HWID and SW Version as is used in original boot.bin in EU FW (e.g i must owerwrite JPN HWID 1202 and SW vers. 290 by EU HWID 972 and SW vers. 580)?
3) If i use the way describe in question 2) with JPN 290 or 300 together with EU 580, then I am not able to upgrade my nuvi, there is an error with USB connection. What is wrong?

Thanks
