Thread: Transform a Nuvi 37xx in a Nuvi 34xx for dummies

What ldr.bin you used? (hwid?)
I confirm that you still have preboot mode.
Just try again with ldr.bin of 34xx.

Ok did try But I will have another go. I see some say to holl=d left corner of the screen others say 25mm down and I think 35mm in.
Which the best to try ?

Many thanks for the help
I might even regain from brick mode
Is it best to downlaod and extract the ldr.bin from Garmin or is there one on here, I have seen some but think it was one of them that caused my brick mode.
Or maybe just me being the brick and not the GPS

Cheers Guys I will post update

enabled all features in region_140 except ecorouteHD and flashed it back as mentioned at end of post#1 and link to post#40.

What have you done to enable features?

in .System\Diag\html
you should have this:

You need to place your thumb finger exactly above the letter G of garmin logo.
If your are upgrading to 34xx never remove the thumb until you see the message that the update is successful on your pc.
If you do backup/rewrite of reg_140.bin never remove thumb finger until you see loading message and garmin restarts. Follow the process exactly as defined in post#1 and most important be patient and there are very few chances to brick your device.

Problem is I do not get as far as a any logo now, just a faint glow, I have been trying approx where G would have been, slso found out from one of the posts the measurements for it. still not got the point where updater finds the device. I will keep trying. I have nothing to lose.

1. Make sure that you have garmin usb drivers installed, updater.exe is opened with usb option selected and your gps is completely switched off.
2. Now place your thumb finger at the top left of the gps and power on your gps by connecting the usb to pc. GPS will automatically goes to update mode and click ok at updater.exe on the pc. Dont remove your thumb finger until you see that message that update is successful on the pc
3. For exact position of the thumb finger you can see the picture that was posted in post#1.
4. Its not hard just do trial and error to get updater mode.

I got it back from brick to full working updated 34## took a few goes and alot reboots to find the extact spot to get in to preboot mode.
Many thanks to all the people that helped.

Now I have a bigger problem !! G/F has gone and bought me a 3590lmt for my Birthday (next week) which is great. She was fed up with me moaning about my Garmin brick and took pity on me.

I don't have the heart to tell her that I fixed it, think I would be wearing it in a place that could hurt alot.

So now I have to put it back to 3760T mode and put it on Ebay. No point in having 2 and only 1 car !

Don't think there are any mods you do on a 3590 is there or am I wrong ?
