Thread: Garmin Nuvi 265WT boot problems

update.txt file is correct, it rewrites the firmware region with 14.bin. Maybe it's not what you need here (actually, you need to rewrite that wrong bootloader), but it's a safe way to check if ldr.bin is executed.
There should be the following files on the SD card (you can omit update.log):
<SD>:/14.bin
<SD>:/Garmin/Updater/0827/update.txt
<SD>:/Garmin/Updater/0827/ldr.bin

If it still doesn't work, then I have a few ideas:
1) Maybe the bootloader has another HWID (why else would it brick the device? Can you give me that device-bricking RGN?), so you need the appropriate ldr.bin.
2) On some devices (at least, on 13xx) the bootloader is responsible for initializing LCD controller. White screen means that it's most likely initialized incorrectly. So you won't see anything even if ldr.bin is executed. Try using update.txt with some command inside that creates files, like "rrgn,14,1:/14-1.bin".
