I use XQ-50 Pro.
Today after updating the firmware to 0.1.9.1 the device is not working. There was no problem in the upgrading process – it finished successfully.
But now, if I connect it to the power cord, the device shows only the xDuoo logo and freezes.
I can’t connect the phone, because of an error: “incorrect pin”.
Moreover, I can’t rollback firmware because when the device is connected to the PC, 10 seconds of pushing on the power button don’t do anything (but before upgrading the device went to DFU mode).
What should I do to bring the device back to life?
