[Garmin] Universal Firmware Patcher for Protected Garmin Devices

[复制链接]
admin 发表于 2017-1-12 22:41:12 | 显示全部楼层 |阅读模式
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 you will be able to check if your device firmware requires this patcher or if it just needs gimgunlock+mapsigpatch or simply an .unl file or old gimgunlock or PGFT.

Important note by MOD: Please check in attached list, in spoilers below, if you need to flash patched .rgn in preboot mode or if you simply can flash patched.gcd normal way because the original firmware does not contain a GSV check yet (GSV: ---)
Montana 680t users: read the note at the bottom of this post.

Troubleshooting
Common patcher flashing failure reasons:

First of all, probably you havent read carefully starting post ;)

Use/download the patcher posted by big-bang in this thread only,
it's not granted files posted in other forums are updated and work fine.

It may fail if: No Garmin USB drivers installed in your pc.

It may fail if: No existing gupdated.gcd removal from device or sd before flashing patched.rgn/gcd

It may fail if: No flash occurs [Patched GCD is ignored by device] Increase version number during patching process see post #562

It may fail if: No hard reset or clear nonvol performed before&after flashing by Updater.exe or sd

Failure using Updater.exe:

You fail when Updater.exe is not opened in desktop when you plug gps into UBS port in pc: device
stays in preboot for a VERY short time, some units only for ~10 seconds. So if it doesn't receive a flash in that time
it goes to the white calibration screen and you have to go thru that and start again.
How to: put your nuvi into preboot by holding the top LH corner of its screen and connecting to a REAR USB port of PC.
Immediately press 'OK' or hit enter key when you see the nuvi's detail in the window to the right of 'USB Device' and
keep pressure on the screen until the flash finishes or at least until 'Loader'/'Software Loading' shows on the screen.

You fail when: Patched firmware.rgn is not in the same directory along Updater.exe when dragged&dropped into Updater icon.

Not continued pressing the top left corner on the screen until the update is complete.

Not suitable USB cable, try another one, even Garmin cable might fail (Error IOU_UTILITIES.CPP etc.).

Wrong HWID firmware, check your garmindevice.xml in Garmin folder.

No patched firmware.gcd renaming to the correct form as suggested in post:
n 253

Failure using Webupdater:

You fail  when Webupdater is not on desktop when dragging&dropping the patched.gcd into its icon.

In Montana 680 not disabled geocache dashboard in map settings before using map as per warning in this thread.

Note: Updater.exe works fine in Win 10/8 x64.

Note2: JNX patcher works fine with patched firmware.

Note4:No problem to update maps with Express after patching firmware.



If you fail once don't worry, be PERSISTENT and keep on trying

and, to avoid to waste your and our time, ALWAYS use gimgunlock+mapsigpatch latest version posted in this forum to unlock your maps
.
[I know weak protection firmware doesn't need it, but my experience in this thread tells me to write this here ]
