T56 bootloader flashing experience on bricked device

Sergiosat

Hello All,I have a T56 which is now not recognized by the PC.
once connected both leds are up and PC is not recognizing the USB device.
I tried all I could including recovery procedure by linking J1 pin 2 and 5, but no way to get it recognized.
In a few days I should get a PicKit 5 interface and I will test I can get connection with the PIC32MZ1024EFH144.
I also bought a brand new PIC32MZ1024EFH144 in case the one on the board will be broken.
However I think I will need at least a recovery firmware to boot the device so that the XGpro software can then automatically update the firmware.
Can anybody help me in providing me a recovery firmware to be flashed in the  PIC32MZ1024EFH144 in HEX format?
is there any possibility to "create an HEX version of the "updateT56.dat" present in the Xgprog software for flashing it in the PIC32MZ1024EFH144.
Any experience about flashing PIC32MZ1024EFH144.
Thanks in advance for any support.
Best regards

OK guys a new update on my bricked T56.I got the PICKIT5 programmer and connected to J1.
Here below the result:
- Reading the Chip ID works and this should mean the chip is not dead and that probably the firmware is corrupted.
- I tried to put MCLR (pin1) to GND (PIN3) and  then connect USB. This should be also a reset forcing the chip to run bootloader, but the PC is still not recognising the device. When connecting pin 1 to GND the led RUN is switching off, but when disconnecting switching on again.
- I tried connecting pin 2 to 5 but no result.
- I tried then to read the firmware, but I got the message "The requested operation failed because the device is code protected." which make sense because the chip is read protected.

All I can do now is to find a firmware to be loaded in the chip after a full erase which can allow at least the bootloader to be loaded in order the device to be recognized by the PC and Xgpro software can update the firmware.

I kindly ask the admin or anybody else who can help if this is possible and to share the firmware privately.

Thanks in advance for any support.

Hi Albano,did all test with different computers and cables with no success.
No way to have it recognized via USB.
Only way id responding is via ICSP but I have no bootloader firmware to be flashed.
Any other idea?

Hello Albano,I already emailed the tech support 3 times, but have not yet got any answer. Hope they will anser me sometime....
I already bought T76 and now testing it. It is impressive! Half size of T56.
Under testing now...
