1. Nuvi 1490, Firmware 6.30, HWID 972
2. Stuck on logo screen after plugging into a computer to update maps
3. The device is stuck on the logo screen, and when trying to update the firmware with a CURE firmware or official firmware the updater gives me a "The GARMIN device is unable to program the requested memory region." during the erasing phase of the update.
4. PC recognizes the gps as an unspecified device but only when connected in preboot mode
5. Any firmware I try to use gives me the same memory error. I've tried Quickcure 3 and the update was successful, but the device behaves the same way and I still can't get it into mass storage mode.
6. USB drivers are up to date
9. I can reach preboot mode
10. No NV backup

I did go through the procedure in "How to unbrick a nüvi" several days ago successfully and was able to unbrick and use the gps before updating maps, but it bricked itself as soon as I plugged it in to update.
Thanks for the help 😊

I hope to get help with my bricked 50 LMT.

1) Bricked device MODEL, Firmware version, HWID.

50 LMT, cannot access files so not sure about FW, HWID should be 2267 but must confirmed once I gain access to the files.

2) Why and how the device got bricked.

It stopped tracking suddenly while driving, since then, I only see the Garmin logo splash screen. It may be linked to the use of an SD card to restore voice command as memory was to small for that last update.

3) Symptoms: what's wrong in your device?

It always shows the Garmin logo as soon as it is under power, the power button will cycle the unit while held but has no effect otherwise, the gps stays on with splash screen on.

4) Does your pc sees your device ?

No

5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.

I have tried all reset methods without success, took battery off to make sure the unit is off before attempting to connect to pc using Garmin Cure 3 and updater without success.

6) Do you have Garmin USB Drivers installed ? Garmin: USB Drivers Updates & Downloads
Yes

7) If you don't know HWID get it by Use program G7ToWin to retrieve your HWID

Can't access the files.

8) Write down if you already read or tried GarminCure3 tool - the new way to create cure firmwares for Garmin devices
How to unbrick a nüvi - step by step guide

I tried that and managed to get the "system" and after that "loading" showing but nothing happened looking at the updater, got the message "no USB device found". I also got a windows message saying "usb device unknown, usb device not installed".

9) Can you reach preboot mode? If no ,have you followed this? Garmin devices preboot mode

I tried many times putting my thumb between the G and A which seems to work one in about 20 trials, what is the exact method for this model?

10) Probably no , but do you have NV backup?

Yes, I have a backup from the device.

Thanks for your help.

11) Once you get a reply and a procedure to follow from our experts, please give an accurate reply about what you did and obtained results.

Hi Guys , I have a bricked one that might or might not be sorted.
It's a Garmin Dezl 700 , the European truck model.
Got fronzen on the navigation screen while driving and after shut down it restarts but won't get past the boot screen.
All it does is show the garmin logo and the loading bar...no version , software version underneath it.
Won't connect to pc and it It doesn't let me do a hard reset.
Haven't tried anything else yet.
Any ideas welcome
Thank you.

Hello,

1) Bricked device MODEL, Firmware version, HWID.
Garmin Fenix 3, 9.60, 2050

2) Why and how the device got bricked.
I went for a run and I was at around 5-6 km into my running activity when the buttons became unresponsive... after a couple of minutes I saw that it exited the activity and also resetted the watch face to the default one. Buttons still unresponsive. I tried to long press the ON / OFF button which actually turned the watch off.

3) Symptoms: what's wrong in your device?
After turning it back again it booted to the service screen that starts with Software version, Time, Temp, Battery, ROM, RAM, Motor test, Charge state.... with backlight on... it also beeped once... it seems that it indicates time (not my time zone), watch temperature, battery voltage and percentage and when I plug it in the computer beeps but does not recognizes it as media storage. Every button is unresponsive except ON / OFF. When powering off and on again while keeping the Star button it activates the vibration test (cannot stop it without force shutdown) or the Back button (than enters the colorful squares animation diagnostic screen) but then becomes unresponsive.

4) Does your pc sees your device ?
Yes it makes that typical USB sound, in device manager is called GARMIN USB GPS. But no media storage mode.

5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.
I downloaded the firmware from Garmin website using the right-click - Inspect - copy link and download.
Tried using GarminCure3 method but gives the next error: "This is a RGN file. got an exception: XRgn::DetectHWIDandSWVER(): ramloader has invalid format Processing FAILED

"

Then tried the methods from "How to make a service (cure) firmware for your Garmin unit", even RGN Tool finds this interesting: "Interesting! This is an RGN within an RGN file Save section to .rgn and open it with RGN_Tool" it thicks only the first part "fw_all.rgn" no HWID or SW version...

Then I tried to modify the .RGN with the hex editor, find the GUPDATE changed RGN to XGN saved it. Reopened it with RGN_Tool now the HWID and SW version became visible... I saved as .RGN with the suggested name HWID 2050 + 01000 + SW version 960 (205001000960.RGN). Placed in the same folder as the UPDATER.EXE, which actually sees the Fenix at the USB part, but when I try to click OK to update, a window pops up "Initializing..." than an error appears "The Garmin device is not responding. Please ensure the following and try again: 1. The Garmin device's interface is set to GARMIN or Host mode. 2.The cable is connected to the correct serial port. 3.The Garmin device is turned on."

This is where I got stuck.

6) Do you have Garmin USB Drivers installed ? Garmin: USB Drivers Updates & Downloads
Yes, the Garmin USB driver up to 2.3.1.2. Listed in the GarminCure3 thread.

7) If you don't know HWID get it by Use program G7ToWin to retrieve your HWID
I know it, because I made a backup from my watch a couple of months ago, and according to the XML file is 2050.

8) Write down if you already read or tried GarminCure3 tool - the new way to create cure firmwares for Garmin devices
Yes I tried

9) Can you reach preboot mode? If no ,have you followed this? Garmin devices preboot mode
I followed the instructions, by pressing the UP button while starting it up, but then the PC gives me an error that USB not recognized, and also UPDATER.exe does not see it until I plug it back again without button presses. Device Manager sees it always as Garmin USB GPS

10) Probably no , but do you have NV backup?
What does NV mean? I made a backup of everything the watch had a couple of months ago. It has a folder REMOTESW which contains an .RGN file. Can this help somehow?

11) Once you get a reply and a procedure to follow from our experts, please give an accurate reply about what you did and obtained results.
The best I can!

Hello,
my Garmin 3598LM is completely dead.

Here the first needed information:

1) Bricked Device MODEL, Firmware Version, HWID. 1258

2) Why and how the device was bricked. Update to Camper 760.

3) Symptoms: What is wrong with your device? It doesn't work anymore. No picture, no sound, no more sign of life

4) Does your PC see your device? No. Neither Garmin WebUpdater, updater.exe nor the PC itself in Explorer.

5) List all procedures you have already tried to remove them and their results and error messages received. On/Off switch pressed briefly, long (20s), even longer (>1 min.). Connected to PC. Connected to 12V in the car. Connected to different adapter.

6) Have you installed Garmin USB drivers? Garmin: USB driver updates and downloads Yes, current driver is 2312

9) Can you get into preboot mode? If no, did you follow this? I reached the preboot mode of Garmin devices when updating to the Camper 760. The update then went through to the end. After that, the 3598 will no longer start and the preboot mode will no longer be reached.

10) Probably no, but do you have an NV backup? no

Many thanks

Hi all,

I have a half bricked Garmin Edge 705. My symptoms are:
Unit will switch on and find satellites, will 'record' a route while it is being ridden but will not save it to the unit. It can't 'see' any maps on either the unit or the SD card. It won't automatically connect to the PC when I connect it, I have to long press the power button, then it will connect.

Due to this, I'm having issues getting into pre-boot mode (long press lap/reset when connecting the device to the PC). I've made a 'new' rgn file with GarminCure3, using 3.10 firmware (unit 'claims' it is running 3.30 firmware) but can't get it loaded as I can't get into the pre boot mode.

What's my next thing to try please?

Details are:
1) Garmin Edge 705, FW 3.30, HWID 0625
2) why and how - can't remember - it's been sat in a drawer for a long time.
3) Symptoms as initial description above
4) Yes, but not automatically. When I plug it in, it will power up and start searching for satellites. I then medium press the power button and I get the charging screen with the word GARMIN and the battery indicator. I then long press the power button and it connect to my PC and I can browse the empty file structure (formatted FAT32).
5) I've tried (via EaseUs software and Windows utilities) deleting the partition and recreating it, formatting to FAT32, tried putting GUPDATE.GCD for 3.10 into the root folder, the Garmin folder and both places on SD card. I've tried copying my folders from a good working Edge 705 (I have 2 working and this non-working one).
6) Garmin USB drivers installed, 2 other Edge 705 units and an Edge 305 connect fine.
7) HWID is 0625 (from another unit as this broken one has no folders / files present after many formats)
8) I've posted in one of the other threads already
9) Can't reach pre boot mode
10) NV backup?

Thanks in advance,
Phil

This involves a semi-bricked Nuvi 1350 (US/ North America I believe). It's old, but worked up to about a week ago. It froze while being used in a car and since then it stays stuck on the logo and keeps going off and on without booting or properly getting into pre-boot mode by plugging in the USB cable. I have tried both GarminCure3 and QuickCure3. Here are some details:

1. My 8GB flashdrive has been FAT32 reformatted as a properly as a FDD bootable device using latest version of RMPrepUSB.
2. The PC does not recognize it, unless I press upper left screen and plugging in USB cord.
3. I was able to get ID information using G7towin64: software version 6.30, HWID 0972, Unit ID 3827336719
4. Garmin Express does not recognize unit regardless of whether upper left is pressed before making USB connection.
5. Webupdater sees unit, but when attempting to reinstall, it says file is corrupt.
6. I have used GarminCure to make 2 firmware files (one cure and one original), but I am unable to install either one.
7. I am able to flash the Quickcure3 firmware (after renaming it to 097201000630), but I am not able to do anything more.
8. I am not 100% certain that I have the correct gcd file for this unit. I found links on this and another forum for nuvi13xxseries_GCDFile_630 and nuvi13xxseries_GCDFile-MTK_630. I believe that my 9720 does not use an MTK file. Garmin seems to have taken all firmware files off of its website. If I had an older version, I might have tried that as well.
9. I have tried renaming my GCD file to gupdate.gcd and putting it into both the root directory and a Garmin subdirectory of the flash drive.
10. I have tried to follow both the instructions at the start of this thread as well as the "How to unbrick a nuvi" doc file, but still no luck.
11. Maybe I am doing something obviously wrong.

Any advice would be appreciated. (Not sure this old unit is worth the effort, but I did like it.)

Have probably similar case like some others had here with Fenix3/6

1) Bricked device MODEL, Firmware version, HWID.
MARQ Captain (American Magic) FW: was 25.85, tried all other starting 3.10, HWID 3248 (from garmindevice.xml) but FW for Captain goes as 3246

2) Why and how the device got bricked.
wrong FW flashed/uploaded, from MARQ Aviator, id 3247
now do not remember was it uploaded with updater.exe or has been stored directly over USB

3) Symptoms: what's wrong in your device?
Same like for Fenixes - progres bar moves until abour 60-70% and stops

4) Does your pc sees your device ?
Device can be detected by Updater, WebUpdater, GE. GE even says it has been synced with Connect system. Device not seen as an USB storage

5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.
Have tried to upload almost all FW versions by converting gcd to rgn with RGNTool
QuickCure.rgn does not uploads over (web)updater

6) Do you have Garmin USB Drivers installed ? Garmin: USB Drivers Updates & Downloads
yes

7) If you don't know HWID get it by Use program G7ToWin to retrieve your HWID

8) Write down if you already read and tried everything in these two threads: GarminCure3 tool - the new way to create cure firmwares for Garmin devices and How to unbrick a nüvi - step by step guide
garmincure3 does not recognize gcd

9) Can you reach preboot mode? If no ,have you followed this? Garmin devices preboot mode
It is kind in a permanent preboot mode

10) Probably no , but do you have NV backup?
m?

11) Once you get a reply and a procedure to follow from our experts, please give an accurate reply about what you did and obtained results.
ok
