Thread: Nuvi 2599 LMT- D - bricked- System Software missing.

aaaa ok, so I do not have to check anything. However, what the g7towin shows is confirmed. So why when dropping the right software the navigation disconnects from the PC and the updater.exe crashes I will be able to run this navigation? Maybe there is some way of uploading the software directly from the SD card? I would be very grateful for the help...

Thanks, i was confusing the "M" chips and should have checked first. Regardless, C4 is 1947 which is what he has according to G7ToWin.

Yes, after the unpacking the device displayed such a message

The most innocuous and common situation where "System Software Missing" message shows is that there is some problem in region 14 (0x0E) where the main system software is stored. That situation usually is caused when a firmware flashing has been interrupted or not completed for some reason. In such a state an otherwise healthy device will revert to preboot mode and be instantly recognized by Updater.exe upon connecting to PC. Usually then simply flashing original firmware via Updater.exe will restore rgn14 and the device will boot and function normally.

In it's most serious but less common manifestation, the message may indicate there is some damage to the physical flash. Hardware damage is not so easily fixed.

If it's physical damage it's unlikely you can flash any way at all. If you want to try from SD then read this thread: [Only registered and activated users can see links. ]. Post #33 explains how to run update.txt commands from a modified boot.bin as an RGN in preboot if the normal SD method doesn't start.

Thanks for your time and valuable advice.

In my case, the Updater sees the device and when I press OK, it shows "Updating 100%" and I hear the voice disconnecting the device and the ID in the Updater program changes to 0 and after a while, I get an error like in the picture. Is it possible that this is physical damage?

Spoiler: image

(the picture is not mine, but it shows similar symptoms. in my case it shows the device and its ID)

Thank you again for sure I will read about it and I will try


And one more question. Let's say it is physical damage to the chip. If I find the same and exchanges it (I need the device) then I can later upload the software presented in the forum ways, or will I have to use programmers and upload something else so that the chip will be supported

This can be actual chip problem. I can't say for sure however but you should try with different USB cables and even another PC using only a rear USB2 (not USB3) port in case the current connection is flaky.

If you cannot return the device for a refund then you'd be better to try sourcing another 2599LM with a cracked screen. It's so much easier to change your screen onto another good device than change flash chips. I've no idea whether 2xx9 devices have a BGA chip but even that is not an easy changeover, re-balling isn't fun.

I'd exhaust all possible ways to reflash firmware first however.
