Hi, tried flashing my 1450 with a cure FW (wrong GCUPDATE.gcd file inserted), the unit won't start on pre-boot, just reboots all over again in loading software. Tried updater.exe and finally caught the unit to flash the cure FW (backup of the original GCUPDATE.gcd + hex edited) then successfully booted now, after which, I flashed again the modified FW (US+PH FW) and not returning ang GCUPDATE back to the .System folder of GPS. After all, I've noticed something different. No GPS version on settings - about, no predictive text, and other stuff. Tried testing it outdoors, no satellite lock. After hours of turned off GPS, tried testing it again without changing anything, surprised it worked (satellite lock)
Did I do something wrong? I was thinking I messed up the GPS system?
I have a nuvi 1250 and 1350 which is unable to enter into usb mode. When i plug in the usb connection the progress bar show about 1cm then it continues to load to the normal gps mode.
So far the only way i am enter the usb mode is to touch on the left top corner of the screen and connect the usb cable until it enters the usb mode. Anyone have ideas?
Formatted my nuvi 1250 with NTFS, Hardware ID: 971, Unit ID: 3636440540 (from G7toWin). I've tried creating a few cure files and uploading them using updater with no success, updater tells me the update is successful however the device just reboots and then sits at the first garmin screen.
If anyone could point me in the right direction, that would be awesome. (hopefully not garmin tech support) :P, I think i'm just following the steps wrong.
Thank you so much :D my 2460 is working like new now!!!
This is great, but... Mine will not go into Pre-boot mode.. It goes through the "Rights" splash and then hangs in the "Loading Maps." splash. I have tried the procedures above in many variations and holding different corners. It seems like it is not getting to the logic that allows you to get into pre-boot. Hmmm.. Any thoughts? Thanks for everything.
Which nuvi ? Try to get preboot mode with USB cable plugged in your pc, when it begin to start, hold On button and finger on screen over "G"
You have to navigate to get to the good.
