You must look for text file called update.log.

You can make your own LDR.BIN
Just take the Gupdate.GCD File or the RGN file that was used to flash the device to its current level.
Run either through RGN Tool (Credits to turboCCC)
Extract boot.bin
Rename Boot.bin to LDR.BIN

ok im doing again , is case sensitive ? because i used Ldr,ldr and now LDR ok

I download attach , decompressed ok put it in 1376 folder (ldr.bin it was a little smaller than i have)and this time apears the battery logo and reboot ok ,buy there was no new reg_140.bin nor log file .
so after that i did it again the wrong way !!! : I rename folder to 1101 and also change ldr.bin with 1101ldr and nothing happens, then i rename again 1101 folder to 1376 and 'voilà' i brick it againnnnnn !!!.
Now its start with Garmin Logo and its freeze.

Do not experiment in renaming folder 1101 to 1376 (or vice versa). This can lead to your device damage. Your current device HwID (1101 or 1376) must be the same as the folder name. Also ldr.bin must be appropriate for this HwID. For device with HwID 1101 you must use ldr.bin from 1101 device. The same is for other HwID.

Good news! preboot i could enter my gupdate.rgn up and now i have my original 3790 then i hard reset and its all ok.
Conclusions: 1) I am very disappointed with myself 2) I learned a lot thanks to you 3) and most importantly, I made new friends!
It is not my intention to give up but I was very scared, not as continuing, sorry.
I go to sleep from being too tired and stressed at least I will dream with my 3790 converted to 34xx with all the improvements made ​​and voice commands Jaja.

at least for my 1350, touching upper left corner while opening updater.exe will work, but on the screen it won't show anything. the usb device option from updater.exe will become available if you can notice that.
