    help nuvi 2597LMT black screen bricked

    I purchased two nuvi 2597LMT that are black screen bricked.

    They can't reach pre-boot. I have done it on other devices but these two cause me grief

    I have tested the batteries and screens on a working 2555 and they are all good.

    The batteries seem to charge when plugged in.

    The PC doesn't recognize the device at all, like nothing is plugged in, no usb error or unrecognized device. I had the device manager open when trying to plug it in and usually it ill try to refresh even on unrecognized devices but nothing at all.

    So it leaves me to try the [Only registered and activated users can see links. ] thread as stated in the stickied thread [Only registered and activated users can see links. ] but the link is invalid. I tried to check the google cache but no such luck.

    I've re-balled and hardware flashed other devices before, so if nothing else will work, I would be comfortable with this with some guidance.

    I'm not really concerned about breaking them on risky maneuvers, they are for learning, I already salvaged the upright usb port on one of them.

    Any help appreciated

    p.s. This forum is awesome, I resurrected two nuvi 1350 and enabled features with your help. thanks all

    Black screen is sign of hardware problem. You can try to reflash internal memory chip with healthy image on programmator!

    My guess is that the units were bricked with a wrong LDR.bin file, so I would probably need to flash the boot region. How do I figured what address it starts and ends? Would I need a working dump or I can manage with RGN tools and the correct GCD file?
