Thread: Is this nuvi 2589 simply Bricked or is it a Hardware Failure?

I'll try a bunch more times, but it looks like I'm seeing the problem where Updater's progress goes straight to 100%, time passes, then it pops a vague "There is a problem" error message. The device didn't get programmed with Cure; it still hangs at the logo without USB, or (if I signal preboot with thumb on G) enables USB only for a few seconds. Thanks for all the coaching so far. I'm trying to read about similar problems, but I get overwhelmed by the sheer number of long threads that search turns up. Due to a concussion a couple years ago I can't juggle as many eggs as I used to.

I will download the region tool to support @kunix's SD Curing method (his post #33 in "Running programs from SD in nuvi").

Edit:

I included That Word in my update so I guess it got auto-moderated. (I thought it was only if it was the first word.)

I tried QuickCure3. I got progress bar instant 0-100% then the "update successful" popup but it didn't help. Hard power off still causes reboot to Garmin logo without USB, preboot (thumb on G) still enables USB briefly.

Meanwhile, GarminCure3 Cure firmware failed to update; progress bar instant 0-100%, nuvi 2589 displays SOFTWARE LOADING..., (USB drops) spin a while, then updater pops up a vague "There is a problem with this GARMIN application" error message.

I downloaded RGN_Tool, opened nuvi25x9C4_880.gcd, saved boot.bin, opened boot.bin in a hex editor, and found the first occurrence of 0C 80 A0 E1. Is that the right thing to patch? What do I do with the edited boot.bin ?
