First time I tried to flashing from usb stick. I have thre original Honda flash file to tis device:

- For SH USB1 - AUD31CF.bin - I can't extract the bin file. Maybe this contain the boot and recovery images. - I can't flash with via usb stick. Its a error message... Maybe

this bin file contain the boot and the recovery images.

- For tegra EC/NC USB2 - ADA_usbdl_VL0.FFF.04_EXT_HFT_param02.zip - Flash zip file loaded up correctly to the device via usb stick.

- For Tegra USB3 - ADA_usbdl_V10096001123_sec_14ada.zip - Flash zip file loaded up correctly to the device via usb stick. This zip file contain a

"ADA_usbdl_10.096.00.1123.enc" file. Can't decrypt or extract. Its a password protected file. I not know whats the password...

I tried to downgrade, with older and upgrade with newer wersions, but not working....

Now I tried flashing via OTG USB on the USB-B system port

I can't find any driver to the device. I found many driver (apx ; nvidia shield ; toradex_usbpcdriver_32_64 ; universal naked drivers ; etc.) but the ****usb.inf file not

contains any record of this device, what they call it:

USB_Install, USB\VID_0955&PID_7102

USB_Install, USB\VID_0955&PID_7102&REV_0232

After the inf editing and With forced install, i can connecting the driver to the device with many "name":

NVIDIA USB Boot-recovery driver for Mobile devices"

NVIDIA Android Fastboot Device

NVIDIA Android Composite Device

Android Debug Bridge Interface

etc....

I found thre diferent driver dll version too:

WdfCoInstaller01009.dll

winusbcoinstaller2.dll

WUDFUpdate_01009.dll

-------------------------

WdfCoInstaller01009.dll

winusbcoinstaller2.dll

WUDFUpdate_01007.dll

------------------------

and

WUDFUpdate_01009.dll in another file size....

the device not aswered to the fastboot.

Fastboot devices

Cant find any device

Only the xiaomflash.exe can read a a devise serial:

015e8b67e833fc08

but, cant flash the device....

After adding the usb and post settings in the virtualbox, i tried flashing the board wint ubuntu.

same as with windows. The device its in the ubuntu usb device list:

but, if i like to flash the device, nothings happened. The flasher wait for the device...

So.....

how can I find a solution for flashing this board?

Its any not public device driver to this device?

How can I flash the SH AUD31.bin?

Becouse i think the Tegra files loaded up correctly via USB stick. Now i must to give a "fastboot -w" command to the device, and then can booting correctly. I tried with

"fastboot -i 0x0955 -w command too". not working.

I think I must flashing the bin file with a eeprom félasher. I have eprom flasher, but the flasher can't flash this eeprom. find any eeprom flasher under 600$ for this

"25C512A" eeprom.

So.....

How can i unbrick tis device?

Any solution? :)

Thanks for the reply

Kind REgads,
