Thread: aera 795 stuck on 'Loader' after fw update (could getting Unit ID from GMA or UNL files help?)

Thanks for your advice Butters,

I think I have tried many, many combinations and timings. You wrote this procedure on this forum several times - have the updater ready, press updated immediately after the Updater recognizes the unit etc. I really tried all of it so many times...

I am thinking there has to be something else preventing it to flash correctly or I am doing something wrong. Let me summarize how I understand the procedure and list some of my questions:
1) I have the cure RGN genreated by the GarminCure3 tool. It says "Processing OK " Unce I click on Updater.exe button it creates a temp folder with the RGN in it

2) I read somewhere the RGN file must be in the same folder as Updater.exe. So I also tried moving this generated RGN file to the same level where Updater.exe is and then launche the updater by dragging the RGN file onto it

3) I have all executables set to start as Administrator

4) I also tried updateing my Garmin USB drives to the latest version (2.3.1.2) and downloaded the newest Updater (2.8.0.0)

5) When I load the GCD file into the RGN tool it shows boot.bin and fw_all.bin with correct HWID (1364) and SW Version (560) but it also shows 4 more "Unknown.bin" files where HWID and SW Version is just NA. Is this correct?

6) There are two official Garmin master reset procedures. The one that also wipes nonvol requires the unit to be in the stand. I also tried numerous times to flash while in the stand.

7) From the "How to unbrick a nüvi" document I understand I should be holding the power button during the entire updating process. This means that after the first phase of updating the unit restarts and then enters preboot mode again. The second phase begins but the Updater only goes to 2 % and then disappears. No message or anything.

8) No matter what happens, if I do not enter preboot it still shows the old SW version (550) and then shows LOADER which is a dead end and battery needs to be removed.

I can make a video of the process if it would be helpful. Also I want to apologise for creating this thread. I believe this should be a part of the GarminCure3 thread.

Thank you very much for your support!
