Thread: Garmin Nuvi 1200 that gets stuck on Garmin logo

Yes i know you made and flashed (normally) a 'boot.bin-only' RGN with updater.exe previously. What i'm now asking you to do is different from that. I want you to modify boot.bin by changing the first instance of bytes '0C 80 A0 E1' to '0C 80 A0 E3' in hex, then use that modified one to make the RGN. It's then used to run the SD text command, not flash the device directly like you did before. Read the Post #33 i linked for you in my previous post, this one: [Only registered and activated users can see links. ].

I don't understand this step

Similarly, read the link i supplied and the changes needed as written in my previous post about backup of region 41.

So, inside the HWID folder there should only be the Update.txt file with the code you passed? If so, done.

Now it's my turn to say i don't understand. Done what, prepared the SD kit with Garmin\Updater\1106\Update.txt file? But not yet used it like i detailed?

If you are unsure of anything to do with the preparation i will make the SD kit for you.

No problem. Look behind the Spoiler below for the kit:

Follow this guide:

• Extract "SD_RGN41_Flash_Kit.zip" to find Garmin folder and 110601000630.rgn and Updater.exe
• Put Garmin folder on a CLEAN microSD card (use a small card if possible, FAT16 or FAT32 only)
• Insert the card into your nuvi with it completely OFF
• Drag 110601000630.rgn onto Updater.exe to open its GUI
• Continue with the previously written guide in Post #2 from Point 4 onwards to place the nuvi in preboot, connect it by USB, start Updater.exe, etc.
• When the process finishes as indicated by Updater giving 'success' message, remove the microSD and post the contents of update.log now present in 1106 folder.

There should now be a new file named 41.bin created in the root of the card. Please keep a copy of it safely somewhere as we may need to flash it back later depending on what happens with further experimentation.

Note: This is entirely at your risk. I've taken care to make the kit correctly and no risk should result in it's proper use in a HWID 1106 device that only has a soft-bricking. However be aware that should your nuvi have a flash chip problem that it may fail at any time and it's most likely that would occur when it's being stressed while flashing.
