I read the entire post that @Butters recommended to me, but to be honest I can not deal with it. Part of the post [Only registered and activated users can see links. ] I made, but I completely do not know what should be in the file update.txt to start up, erase all files and then reinstall them.

Changing the chip would not be a big problem for me. I am playing electronics with a hobby and I have hot-air, a microscope and other things needed to play with electronics. And I've already exchanged chips on several phones. But never those that need to be programmed and i do not have a programmer nand; / And here is the biggest problem. If nothing else will help then I will probably leave it.

In all likelihood the only region you need to re-flash is region 14 but for completeness we should attempt all three (14, 127 & 158) and also try to get a copy of it's non-nov in 154. Let's skip to the chase and try with a modified boot.bin seeing you've already started with kunix's method in Post #33 because if that won't work neither will a direct flash from the card. For this i'm assuming you've made the hex changes to boot.bin (first instance of 0C 80 A0 E1 replaced with 0C 80 A0 E3). So first make the required text file using NotePad by carefully copy/pasting the following then saving as Update.txt only:

Code:

• Ensure there are no spaces or carriage returns/extra lines anywhere before saving the txt file.
• On a CLEAN microSD make a folder Garmin. In that folder make Updater. In that make 1947 and place the Update.txt file in there. (x:\Garmin\Updater\1947\Update.txt). Don't have anything else in 1947 folder
• Open the file nuvi25x9C4_880.gcd in RGN_Tool and save each of the last 3 sections in turn naming them appropriately to match the txt commands (resources_7F05 as 7F.bin; resources_9E05 as 9E.bin; fw_all as 0E.bin)
• Place the 3 bin files in the root of the card, next to the Garmin folder (not in it)
• Ensure the 2599 is completely OFF, hold the power button to force it off if necessary, place the microSD into the device
• Open your modified boot.bin with RGN_Tool and save it using the RGN button named only as 194701000880.rgn
• Drag the rgn file onto Updater.exe and leave its GUI open and visible on your desktop ensuring the radio button next to 'USB Device' is selected on Updater's GUI
• Have a 'known-good' microUSB cable connected to a REAR USB2 port of the PC (don't use a hub or front or USB3 ports)
• Connect the device to the cable and immediately you see the device details appear in the window next to 'USB Device' click the 'OK' button.

You shouldn't need to put the device into preboot as it should have defaulted to that state when the system software message shows. Hold the screen appropriately if you want however.

Good luck.
