It doesn't always happen but certainly it isn't a totally unknown occurrence to get "System Software Missing" on the very first startup after full fw conversion with HWID change. In that case it just needed to be forced completely off by holding the power button down, then when re-booted it would have started normally. Sorry, i do try to cover the most likely outcomes in my posts but giving all possible scenarios in advance can just confuse and frighten many users. There's also some chance of an an error when you made the SD kit for the full conversion - e.g. an incorrect TXT "xrgn" command or wrongly placed BIN file resulting in a mis-match of fw files written. The file "update.log" will disclose all errors there, if any.

As it is, i'm often told my posts tend to be overly wordy ... like this one .

Even when I pulled out the SD card, problem stayed the same.

The card is ignored anyway if left in the device when "last_id.bin" file remains in the HWID folder.

I think that was the case because in update.txt, on SD card, first line was "del,0:/.System/gupdate.gcd" so it probably deleted old FW but for some reason couldnt load the one from the SD card.

No, that's got nothing to do with it. The GUPDATE.GCD file (if present) is only read and initialized by the device if it's deemed appropriate fw and then only used if it's a higher version than is already in the device's fw regions (i.e. 14 [0x0E] & 127 [0x7F]). If so, it will it be extracted and flashed to those regions (a bit like a self-extracting EXE file does on a computer). The DEL command is therefore usually included as the first line of update.txt to remove it just in case it otherwise does somehow get initialized on the next reboot cycle, but if the GCD file's not present then the update.log will show an error for that one command and update.txt will simply continue on with the remaining commands.

Please post the content of the update.log file so we can confirm the above.

... In that moment I thought that I bricked the device and that it will be the same case our colleague @gigidel had with his Motorrad VI, but either way I wanted to try loading FW using WebUpdater.

Again, sorry if that brief concern was due to any info i omitted to give.

Regarding gigidel, i don't recall any posts of his about bricking a Nav VI. Can you point me to that please? It's ok if it's in another forum.

So, loaded EU FW in RGN tool, saved it as .rgn file, used webupdater to load it in pre-boot mode and everything went well.

You simply repeated what was previously done with BIN files via SD card, if that was done properly nothing actually changed there subsequently. The flash in fact works exactly the same whether using SD card method, or by Updater.exe/WebUpdater in preboot. SD just is easier because you don't have to find preboot which can be difficult for some users, particularly with modern devices.

After restart, I selected "Other" region among many other offered (not just US, China and Taiwan as was previously) and I was able to select my language in text option of the device. In Device info and GarminDevice.xml, software version was 350 (correct EU version) and HWID was 1541 (correct EU hwid). Garmin Express recognized the device and offered me an update of text files and also, interestingly, Chinese map that was previously on the device. Maybe because the Device ID was still the same, I dont know...

The device's Unit ID remains the same with this conversion. It's not possible in fact to change it's regional map entitlement which is tied to that UID which is why you got offered CN maps. Although the Garmin servers will use UID to satisfy map entitlement, they use HWID to allocate other files, firmware upgrades and all other software. For all intents and purposes as far as its ongoing interactions with Garmin is concerned your Nav V is now a Western device HWID 1541 but with factory-allocated (OEM) CN mapping.

Nevertheless, after putting the EU maps, I can confirm that everything is working fine.
Couldnt do it without you @Neil.

Great result of course and thanks so much for acknowledging my help. Surprisingly few users do that even when they get a trouble-free smooth outcome, without any hiccups like you had. I'll help me if you follow up with answers to the bits in blue above. Cheers.
