Thread: GarminCure3 tool - the new way to create cure firmwares for Garmin devices

fdiaconu
Now I totally don't understand what you've flashed and what you haven't flashed.
Both RGNs I've sent to you lack boot.bin, so the nuvi doesn't reboot after flashing is finished and it's ready to flash one more RGN.
You have to turn it off by holding the power button and then turn it on and see how the newly flashed firmware behaves.

I flashed with file 097201000580.rgn from you. It stays with blank white screen and is shown in Device Manager as Garmin USB GPS for indefinite time.
After restart, it continues with the blank white screen but is no more seen in Device manager, unless restarts again with top left corner of dispalay depressed.
I also flashed with original Garmin file in GarminCure3 ORIGINAL and after a first short phase, Nuvi screen changes to Garmin logo with SOFTWARE MISSING message and device disappears from Device Manager. If I leave it, an error message comes. If I restart (in short time, with USB to computer still connected), update continues in two 0 to 100% stages and final message says Update successful.
After restart, it comes with blank screen followed by Garmin logo turning on/off.


Is it possible Garmin put on purpose a feature in firmware to sense broken (interrupted) digitizer replacement to avoid their units being repaired?
I understand GarminCure3 was tested on units with accidentally deleted files or formatted drives, but did someone used it on units with broken and later replaced digitizers? Or did someone successfully replaced a broken digitizer on Nuvi 13xx series?

@fdiaconu

Did you try with FW that i send you?
What is result?
If you have error software missing when you flash with 0972 then you have 1104 and not 0972.
I have 0972 NVM backup i can send you,but you must first try with 1104 FW if this FW turn your nuvi on.
Try with both file that i send you and report situation.If wont work i send you my NVM backup.

If I try flash with 110401000580.rgn file, I get Updater message "No updates are available for your product"

Okay, I understand now.
So, the CURE firmware behaves exactly as the original firmware. I haven't seen this before. It could be that the firmware should fails to initialize the digitizer and then reboots.

I think it's some bug in the bootloader that makes it display "Software Missing" instead of executing boot.bin.
The firmware is executed normally, so the HWID is correct, it's 972. The HWID isn't stored in NVM, it's stored in the bootloader itself.

@Kunix

Do you have my NVM backup?
Try with this.

I should have it. Or I can make my own.
Anyway, as boot.bin is unable to run, we can't flash it. Because the bootloader doesn't accept the nv region.

I wonder if the nuvi booted up before the touch panel (digitizer) was replaced ?

Dear Guru,

Need your advise and help. I have flashed nuvi 1260t with the wrong firmware by mistake The information which I got from G7ToWin is Nuvi 5 Series Software Version 3.00 with the ID 723.

I have tried GarminCure3 and make Cure and Original firmware from the gcd original firmware but still no luck. The latest status of nuvi 1260t is always boot with the white screen (no garmin logo).

Please advise what should I do and if any service firmware for 1260t, please please please share with me.

Thanks a lot.

Your device is dead.
