Garmin PND固件补丁工具 v.1.10
新款Garmin PND设备（2014年以后）或者部分安装了新固件的老款设备无法使用解锁地图因为它们同时需要.gma文件和MSV（地图签名验证）。
固件信息列表: 12-9-16_fw_list.rar
口令:gpspower.net
说明:
MAP: Yes - 需要地图解锁码。 JetMouse keygen可以生成此码.
GMA: Yes - 对于FID>2200的地图需要gma解锁文件。旧的解锁工具gimgunlock-0.03 (无MapSigPatch)或其他解锁工具都可解锁。
MSV: Weak - 简单MSV验证。gimgunlock-0.03+MapSigPatch可解锁，无需固件补丁。但对于NTU地图 (CP 65001)你还必须修改CP值.
MSV: Strong - 强MSV验证，你必须对固件进行补丁，同时使用解锁工具对地图解锁。
GVS: Yes - 固件签名验证。
警告：固件破解有一定风险，请备份设备上所有文件和NV内存。下列步骤执行前后请用sd卡备份 Nuvi NV (region41)然后清除 NV。
5) 拖拽gupdate.gcd到补丁工具窗口。补丁工具将生成'gupdate_patched.gcd'到指定目录。非GSV设备可跳过步骤6-8。
6) 下载RGNTool。 RGN_Tool用于转换RGN/GCD文件格式
7) 拖拽gupdate_patched.gcd到RGN_Tool，把它保存为.rgn文件。 注意: 文件需要以'xxxx01000yyy.rgn'这样的格式命名。 'xxxx'是4位HWID，'yyy'是软件版本号. 这个帖子包含这样命名的理由
8) 下载Updater.exe。 Garmin Updater.exe v.2.8.0
把Updater.exe拷贝到固件.rgn同一目录，拖拽.rgn文件到Updater.exe图标。Updater.exe会被开启，请选中'USB Device':
再次确认设备中的所有gupdate.gcd都已经被删除，否则请停止并检查。连接你的设备到PC的机箱后USB端口，并且不能通过usb集线器。设备会立刻开机，在出现Garmin图标之前，用力按压屏幕左上角进入preboot模式让Updater.exe发现你的设备。这是设备详情会显示在'USB Device'旁边。立刻点击OK按钮 (保持按住屏幕左上角直到刷机过程结束，Updater显示"Success!"信息)。从PC安全的拔掉设备。有些设备进入preboot方式略有不同，请参考： Garmin devices preboot mode
9) 清除Non Volatile内存[也叫做NV、NonVol或者nonvol] (注意: 如果不想以后碰到诡异的问题，请照做!) 使用 清除NV或重置设备 如何重置
注意: 将来更新固件时，记住要删除设备内所有gupdate.gcd然后把补丁后的gupdate.gcd放到TF卡中 [sd:\Garmin\gupdate.gcd]，不要放到设备内卡的.System目录，万一GCD文件有问题，放到.System可能导致设备无法启动，但放到外卡仍可拿出TF卡补救。万一设备误刷了官方带有GSV的固件，那么仍然需要使用RGN方式才能刷回。

固定补丁完成后，重置设备并在使用解锁地图前，在地图设置中禁用Geocache Dashboard，否则设备会锁住。

This is anuniversal firmware patcher for protected Garmin devices.
Many devices recently have a strong firmware protection and cannot use unlockedmaps because firmware requires .gma and has MSV ( Map Signature Verification).
In this list you will be able to check if your device firmware requires thispatcher or if it just needs gimgunlock+mapsigpatchor simply an .unl file or old gimgunlock or PGFT.
Important note by MOD: Please check in attached list, in spoilers below, if youneed to flash patched .rgn in preboot mode or if you simply can flashpatched.gcd normal way because the original firmware does not contain a GSVcheck yet (GSV: ---)
Montana 680t users: read the note at the bottom ofthis post. Spoiler: list

Legend:
MAP: Yes - it verifies the presence of a valid unlock code, to unlock an .imgyou can simply use JetMouse keygen.
GMA: Yes - it verifies the FID limit (2200) and the presence of a valid *.gma,to unlock an .img you enough to use the old gimgunlock-0.03 (withoutMapSigPatch) or one of its derivative.
MSV: Weak - it verifies the validity of map signatures in a simple way, you canunlock an .img using gimgunlock-0.03+MapSigPatch (without patching yourfirmware), but in case of unicode maps (CP 65001) you must modify the CP value.More info here: Temporary authentication of Unicode maps (codepage 65001)
MSV: Strong - it verifies the validity of map signatures more complicated way,in this case you need to patch your firmware and unlock an .img using anycorrect unlocker.
GVS: Yes - it verifies the validity of firmware signatures, to install thepatched firmware for the first time you have to use Updater.exe.
Warning - Improperuse of this software can damage your device: It's strongly recommended tobackup your device files and Non-Volatile memory before playing with firmware. How to backup Nuvi NV (region41) withsd and then Clear Nonvol. Do it both beforeand after the following procedure.
Procedure to use the patcher and to load the patched firmware in prebootmode ("GSV: Yes" devices) :
Prerequisite:must have Garmin USB drivers installed to use Updater.exe.
1) Remove any gupdate.gcd in your device.
2) Set it to Mass Storage. How to set nuvi 2012 models (MTPdevices) to behave like USB disks (MASS STORAGE)
3) Download the patcher (Version 1.10 updated on 28-07-16):

(Changelog:
Improved the universal pattern (for GVS) to make it more accurate. Problem withnuvi 57/58 and nuvi 67/68 solved.

Added DriveAssist 50 thanks Philipych
DriveLuxe50 and Drive and Drive Smart 60/70 added [thanks Philipych])
Earlier:fixes to have a more universal and flexible tool.
4) Copy the patcher in a directory along with your firmware gupdate.gcd How to get a Garmin device firmwareupdate without Webupdater?
Note: be sure to get your device's CORRECTfirmware for its HWID, check it in GarminDevice.xml: Garmin Devices, their related HWIDnumbers and Software update Pages links Table or here: How to find your Garmin Device's HWID.Do it or you can brick your device. This is particularly easy to mix-up forsome 2xxx devices which have both 'C4' and 'normal' version firmware. It takesmere seconds to insure against flashing a mismatched HWID firmware which willresult in hours of grief and possibly a hard-bricked device which can't berevived at all or without expert assistance.
5) Drop the gupdate.gcd in its window, the patcher will provide the patched gcdfile as 'gupdate_patched.gcd' in your chosen directory. See below if your device has "GSV: ---" because you can skip Steps 6-8 asyou don't need to load using an RGN file [but you can if you want to that way].You can flash even initially with a patched GCD file as explained. If your device has"GSV: Yes" then you must initially flash it with an RGN file usingUpdater.exe so continue on with Steps 6-8. Regardless of method used doStep 9 to finish.
6) Download RGNTool from here: RGN_Tool - Utility to create/convertRGN/GCD
7) Drop your gupdate_patched.gcd in RGN_Tool and save it as an .rgn file. Important: Saveit only in this format 'xxxx01000yyy.rgn' where 'xxxx' is yourused firmware's 4 numeral HWID and 'yyy' is the software version. See this post for namingreason safety and procedure.
8) Download Updater.exe from here: Garmin Updater.exe v.2.8.0
Copy Updater.exe in a directory along your firmware.rgn, drag the .rgn inUpdater.exe icon, Updater.exe will open, enable 'USB Device':
Remember you must remove any previous gupdate.gcd if it's in your device before flashing any updates with an RGN file like this. If you forgot tocheck, stop and look now. If gupdate.gcd is present in the device's .Systemfolder remove it from there before going on.
Now plug your device to only the PC's REAR port [strictly no hub use either],the device will start and immediately, before or as Garmin logo appears firmlypress upper left corner of screen to get preboot mode and make Updater.exe seeyour device, at the point the device details show in the window next to 'USBDevice' immediately click OK (still holding upper left corner until theflashing process is finished and Updater shows "Success!" message).Safely unplug device from the PC. Some devices reach preboot differently, checkyours - All devices Preboot Mode : Garmin devices preboot mode
9) Clear Non Volatile Memory [aka NV, NonVol or nonvol] (note: if you don'twant to get weird problems later, do it!) Nuvi: Clear Nonvol or reset yourdevice How to reset a Garmin device
You are done, your device is unprotected, now you can use every kind ofunlocked maps (NTU too).

NOTE: To flash a firmware updatein the future, just patch the new gupdate.gcd, remember to remove any previousgupdate.gcd in your device, then flash new fw safely and easily only by placingthe patched gupdate.gcd in microSD [sd:\Garmin\gupdate.gcd] not in Device's.System folder. The reason being that if the GCD file is faulty it could brickthe device in .System ['brick' as in prevent it from booting]. If it causes aproblem stuck on 'loader' when on a card, removing the card removes the problemand the device will work normally. You can even flashinitially via patched GCD file if your unit has no GSV in firmware. If youaccidentally load a new version of original [unpatched] firmware and yourdevice has "GSV: Yes" then you'll need to revert to the RGN method.

Warning for Montana 680 users:
after loading patched firmware, reset the unit and disable Geocache Dashboardin map settings before using unlocked map or the unit locks up when it isselected.
Thanks to this forum and its memberswho inspired me
Ifyou fail, before posting, read "troubleshooting" in post #2
WARNING: don't use files posted in other forums, not original and not updated,they can hardly brick your devices!
