Universal Firmware Patcher for Protected Garmin Devices Universal Firmware Patcher for Protected Garmin Devices v.1.10 This is an universal firmware patcher for protected Garmin devices. Many devices recently have a strong firmware protection and cannot use unlocked maps because firmware requires .gma and has MSV ( Map Signature Verification). In this list (http://www78.zippyshare.com/v/CWAOqHso/file.html) you will be able to check if your device firmware requires this patcher or if it just needs gingunlock+mapsigpatch or simply an .unl file Rating: 5

Hi, the link is dead for the patcher, could you re-upload it ?

Would be interested as well. Seems like on the previous posts only the patchers for specific devices/HWIDs are available.

Or is it always only the HWID which is changing in the update.txt? Could I change this by hand to my HWID and thats it?

Cheers

Hi

I tried to update my Garmin 1490t and the device was not recognized:

Processing file C:\Backup\Download\Garmin\firmware\GUPDATE.GCD

Firmware version as specified in GCD file: 6.30 for nuvi 13xx and 14xx.
Firmware name: Firmware version 6.30 for nuvi 13xx and 14xx.

Applying rule set MSV... No matches.
Applying rule set GVS... No matches.

Any ideas how i can fix this? Thanks.

That mean that you can install map without patching firmware.

Just figured out the problem. Previous I was unpacking the RAR file with the Manjaro Archiving tool. I just booted into Windows and used 7-zip and the small version of the map is now showing on my GPS. So problem solved.

Actually you never had a firmware problem, because as said above your 1490's firmware doesn't need patching at all and indeed wasn't patched. It shows in your quote it doesn't have either MSV or GVS in it.

I have a Drive 40. Complained about a corrupted map when I added an unlocked img on sdcard/Garmin. Patched the firmware according to instructions (patcher, rgn_tool, updater). No errors reported.

IMP Patcher (v1.1) identified correct model, but reported HWID of 0 ?
I only used the HWID to name the rgn file, correct ?

Now device is not complaining about corrupted map. But map is not shown under myMaps.Is copying the img to the sdcard sufficient?

Thanks for any help.

That's not a concern and is normal with many modern devices. RGN_Tool will also show HWID '0'. Other tools such as gfw.exe can show the HWID but as hexadecimal. For Drive/Drivesmart 40-50 series HWID 2267 that's 08DB in hex.

Yes, fail-safe naming is 226701000570.RGN for V5.70 firmware.

It depends on naming and placement in the card. Your device should recognize <any_name>.img in Garmin root folder but if it's not recognized change the name to 'gmapsupp.img'. Or you can make another root folder named Map and use <any_name>.img in there too. The *.img must be correctly unlocked of course or you'll see "Can't Unlock Maps" message.
