GarminCure3 tool - the new way to create cure firmwares for Garmin devices

**egcoronel** · 1st June 2018, 08:41 AM

Is someone still here. I have a Nuvi 855 which I wanted to use again. I tried updating the firmware but my laptop suddenly powered down. Now I can only see the Garmin Logo in the GPS. I can do a Pre-boot but that's about it.

I have followed and downloaded all the tools:
GarminCure3
GarminMapUpdater
Firmware - I have tried looking for my model online but I can only see a .exe which I can't use in GarminCure3

I downloaded a .rgn Nuvi8xx_regionfileonly_470.rgn and tried using it in GarminCure3 which I then got an error message.

Processing C:\Users\Eric\Desktop\Garmin\nuvi8xx_regionfileonly__470.rgn
This is a RGN file.
got an exception:
XRgnSection::Load(): REGION_HEADER.const52!=0x52 at offset=0000002D

Processing FAILED

Can anyone help me?

Thanks in advanced

Unfortunately your nuvi runs a version of Linux not the usual proprietary Garmin OS. I don't think this Cure firmware can be used in any nuvi 8xx series devices. You likely need a different solution, maybe someone knows how and will post here or you might need to start a new request thread.

Thanks for the reply. What do you mean by creating a new request?

Thanks

Actually i wrote "start a new request thread. Click on either 'Garmin Receivers Firmwares' or 'Garmin Discussion' in the main Garmin GPS Systems sub-forum and then click on the orange-colored "+Post New Thread" button to make a new request thread.

The error massage from Updater.exe (IOU_Utilities.CPP-203-2.7) means the flash was aborted and no changes have been made. Try again, move very quickly to press OK immediately the the nuvi's details show in the window as in your second image, be sure to keep steady pressure on the screen until the flash is established properly (indicated by 'Loader' or 'Software Loading' message on screen).

Hello!
Is it possible to make the firmware of СURE for collars DС50, T5, T15?
I want to connect them as an external drive.
Thank you.

The collars aren't Mass Storage devices. Therefore they're don't need 'curing' as such.

my friend put a wrong software in his nuvi 760 and and i have tried to solve this problem using Garmin Cure tool. First I have downloaded the proper software ver. 4.90 and the cure software was installed as well.
Afterwards the device has been formatted and I tried to put original software which I got via Garmin Cure tool but the garmin Webupdater didn't recognize my device at all..what did I wrong? I would like to emphasize that
I tried to install the original software trough updater.exe(prebbot was not possible) but no success.
