system software missing
I have problems please help! My Garmin nuvi 2547LMT device crashed during the update. Now when it turns on, "system software missing" is displayed. The USB does not detect my laptop. Please for instructions on how to make a flash on an sd card? Thanks (sorry for my English I use translate)

At it's most benign, "System Software Missing" message means that the main firmware in region 14 is either absent, incomplete or corrupt and therefore the device cannot boot. In such a case the device defaults to a stable pre-boot mode when the message is on it's screen and can be connected to a computer to be seen in Device Manager. It won't be seen by File Explorer to browse the internal files system though. It probably won't be getting far enough into the booting cycle to read from an sd card because of the non-functional firmware so firmware cannot be flashed that way. So the best method is to use an RGN firmware made with RGN_Tool, connect the 2547 to PC and re-flash the firmware using Updater.exe.
If it's not showing in Device Manager then the message means something much worse and likely fatal involving a flash chip problem.

try at yout OWN RISK because your info are poor/little
so as i told you on PM if you want to try:
I put you 3 possibilities solutions
first test TEST1, then TEST2 and finally with the sd
for tests 1 and 2 just connect the garmin to the pc
then transport file 1 or 172201000430.rgn file above the updater file
then a screen opens and check USB Device and then press ok

just like you wrote! Nothing happens I also tried with rgn but there is no response (flash sd) also the updater shows the device and every time I click OK it writes "there is no usb device"

Oliks, try with WebUpdater!

Assuming it could be detected by WebUpdater, WU loads a GUPDATE.GCD file into the device if there's a higher version fw available and on NEXT SUCCESSFUL BOOT the GCD file is detected and initiated to update the firmware. His device cannot boot presently and it's unlikely to be detected by WU anyway.
Please use G7ToWin to check your device's actual HWID number. g7towin64.zip (Look at thread named "Use program G7ToWin to retrieve your HWID" in G P S P O W E R . N E T to see how to use it properly in preboot mode). It's absolutely essential to use the correct firmware while attempting recovery. Please also say what "update" you were attempting when the software missing message appeared. Were you using GarminExpress or WebUpdater for a normal routine update, or were you trying to cross-flash it somehow when this happened? It's important to tell us everything about the device and its history.
As your device has preboot available it's possible it can be fixed. It likely cannot use the SD card method because it's not getting far enough into the boot cycle to read the card. In any case, Ldr.bin is initiated by fw_all.bin in region 14 and presently it's not working. There is a way to modify the Ldr.bin (boot.bin) and use it as an RGN to initiate Update.txt on SD however.
First things first however, give us as much info as possible.

i used the web updater because the older version offered me a newer version then the operation was interrupted for some unknown reason. I only have the original file "gupdate" that's all! The device is nuvi 2547LMT, HWID is 2077. My computer does not detect the device, it does not see usb and I can't do anything. Every time I turn on the device, the message System soft.miss is displayed ... even if I hold my finger on the bottom right, a reset occurs and again on the same.
