omap4boot usbboot never finds device

mj-sakellaropoulos commented 3 years ago

What conditions will allow usbboot ?

usbboot is unable to find the device, it never enumerates with the required VID:PID.

waiting for OMAP44xx device...

That utility only works when the tablet is in usbboot mode (the device appears to be off, but is detected by PC as Texas Instruments, Inc. OMAP4430). usbboot mode can be triggered by the following methods:

via UI option in Hashcode 2014 U-Boot port: navigate to the advanced menu option via power button
via console command in Hashcode 2014 U-Boot port: just run kc1_usbboot
via fastboot: fastboot oem idme bootmode 4003; fastboot reboot
via adb (recovery): adb shell idme bootmode 4003; adb shell busybox reboot
via pin shorting: described in this old XDA post

usbboot/omap4boot usage: described here

If your device does not have major hardware issues, you can pretty much use the shorting method to recover from bricks.
