Hello

At the beginning, I'm sorry, but my English is not very good. Then I would like to ask you for help with my nuvi 2599.
I bought it with damaged software. I wanted to upload it again using this method [Only registered and activated users can see links. ]. But either this method does not work in this case, or I am doing something wrong.

What i know!

1) Model:

Nüvi 2599 LMT-D, HWID: g7towin shows -

2) Why and how the device got bricked.

I don't know

3) Symptoms:

Usually, the inscription is displayed "System Software missing", but sometimes it is in the bootloop and the
backlight blinks and turns off

4) Does your pc sees your device ?

As it is in the bootloop, it's not, the PC only sees it running in the pre-boot

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

I tried this [Only registered and activated users can see links. ] but without result.

I did everything in accordance with this manual and when I start the device in pre-boot mode, SYSTEM SYSTEM pops up on the display and when I click OK in the Updater.exe, it shows up

and in the Updater.exe the device id changes from normal to 0

and finally an updater error pops up and the device resets.



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.

And here is a small problem. G7ToWin shows that HWID is 1947, but I read somewhere here on the forum that there are 2 versions of the device and the latter works on the Mediatek chip and has other HWID. So for sure I opened the device and wanted to check what is in my device. And I saw something like that

Is Mediatek and HWID should probably be 1758? Is G7ToWin wrong, or just someone uploaded the wrong software and that's why it shows.


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 have read both topics and nothing helps or I am doing something wrong

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

Yes, I can.

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

No

11) Files that i use:

a) nuvi25x9C4_880.gcd
b)Created cure firmware name: 194701000880.rgn


I would be grateful for any help
