Leave device power plugged in overnight and it might recovered on its own. Nothing to loose.

Do not PM me with questions. That's what a forum is for.
1) Bricked device MODEL, Firmware version, HWID.
2) Why and how the device got bricked.
3) Symptoms: what's wrong in your device?
4) Does your pc sees your device ?
5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.
6) Do you have Garmin USB Drivers installed ? Garmin: USB Drivers Updates & Downloads
7) If you don't know HWID get it by Use program G7ToWin to retrieve your HWID
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
9) Can you reach preboot mode? If no ,have you followed this? Garmin Updater.exe v.2.8.0
10) Probably no , but do you have NV backup?
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.
I'm writing this because sometimes it needs a lot of posts before understanding what has been already tried and what is needed. Being precise will help you and us in saving a lot of time and curing it
Thanks
1. Garmin DriveSmart 50LM, Firmware 540, HWID 2267.
2. Tryed to update unlocked firmware, but RGN tool doesn't show the HWID so I wrote it by myself.
3. After update device pops up message: "Software is missing!" and cannot load.
4. It cannot be seen from the computer as device anymore.
5. Tryed all the procedures with GarminCure3 but the device cannot boot and immediately shows that Software Missing.
6 I don't have any backup files.
I hope someone can help, please!
Thanks in advance!

In it's worse meaning 'System Software Missing' can be quite a serious problem, however in most cases provided you used the correct firmware for your device it means that region 14 containing the main system software (fw_all.bin) is corrupt or even completely empty (i.e. erased, but not properly rewritten during your previous attempt). In that case the device should have defaulted to preboot mode and will remain in that state when turned on until the firmware is fully flashed to it.
To confirm it is now in preboot, connect to PC, no need to hold the screen, look at [Only registered and activated users can see links. ] for an explanation and pic of how it should appear in Windows Device Manager when in preboot. If it does appear there, then follow the rest of this. If it doesn't show there it may be hosed differently.
- Remake the patched firmware entirely from scratch. Don't be temped to use whatever you previously patched, please get a 'known-good' original fw from Garmin server, here:
Code:Please Login or Register to see the links- Don't override the HWID from '0000'. Although the HWID of 2267 is correct, probably the device itself knows to initialize that to correct value using it's bootloader. It's not unique to your DriveSmart, many modern devices are the same.
- Observing the RGN file safe-naming convention (226701000540.rgn), load the patched file to Updater.exe and select the USB Device radio button. When you connect your device the detail should immediately appear in the adjacent window.
- Press 'OK' on the GUI and wait for the flash to finish.
- It should now boot normally with patched firmware.

Thanks, I did it!
My mistake was exactly renaming the HWID
Cheers!
1) Bricked device Garmin 465T, Firmware version, HWID 943
2) Got it from the Garage sale
3) Symptoms: The device has a Garmin logo Boot Loop
4) Does your pc sees your device : Only when is flashed with the "Cure" firmware
5) The Pre Boot mode works and the device can be flashed:Tried 4 different Firmware revisions included the last one 4.2.
Quick qure was able to set the device to USB mass storage. I tried to format the memory as NTFS recover back to FAT 32 using RMPrepUSB.Tried with absolutely no data on the internal memory and with original data,no luck.The Garmin never makes Garmin Device .HTML when the data is deleted.
When is flashed with the "Cure" Firmware stays connected to the PC ,but when I Flash it back to the Original Firmware keeps doing the same thik:Garmin Logo boot loop.
Have no NV backup.
I`m running out of options.Recently the friend of mine brought me a 2757 with almost the same symptoms,the only difference is that the quick qure does not help at all and the preboot mode works intermittently.
Any suggestions?
Not sure why you'd want to format the 465T as NTFS before recovering to FAT32 but that wouldn't have been harmful in all likelihood.
So, are you saying the device has not been formatted at all or it has but hasn't been formatted by RMPrepUSB? It might only seem empty and there's something still there not obvious maybe because you don't have folder options in Windows set like this:
[Only registered and activated users can see links. ]
About the 2757, it may have a damaged USB socket if it only can only enter preboot intermittently. Try other USB cables. Are you sure QuickCure was loaded? Regardless, sometime it doesn't work and you need to use Cure3 made from the actual device firmware. You really need to have consistent and reliable preboot access to load an RGN file anyway.
I have tried to format it in NTFS ,because I ve seen some damages on internal files which do not allow to the system to boot up normally.My computer shows the hidden files by default,so nothing left I'm pretty sure....
It clearly has very serious corruption but provided that's only in the visible file system (region 48) and not in some other essential region like 41 you should be able to recover it. Try again with RMPrepUSB and if it still fails to format it in FAT32 try with Low Level Format Tool:
Perhaps even MiniTool or EaseUS free partition managers can handle it. Then afterwards you can do the format again properly with RMPrepUSB so that it's acceptable for Garmin's OS. There's more than one way to skin a cat (or format in FAT).Code:Please Login or Register to see the linksGarmin devices formatted in windows are often problematic and if done with a mac inevitably give trouble.
The Low Level format tool did not help either.Proceeded ,completed,formatted back with RMPrebUSB,the same result-Flashing Garmin logo for a second or two and reboots by itself....![]()
