I bricked a gpd pocket at one point and one of my proudest accomplishments was unbricking it. I was trying to run openbsd on it and openbsd was not happy. so I install some firmware(bios) with all the options unlocked. I then proceeded to disable usb3, the idea here was that I knew obsd had some usb3 problems and disableing it would force usb2. however it had the effect of disabling all usb on the device. On the gpd pocket everything is usb, so the keyboard did not work and no way to get back in the bios and reenable it. At this point I would go for a cmos reset. but the gpd pocket has no cmos reset capability. Completely stuck, even tried to drain battery to see if that would do something. I saw a forum post you could pull the mainboard and reflash the winbond cmos chip, so I bought a cheap chip flasher and connector kit but was not having much luck. But did not know why so it sat on the healing bench for 2 years. At which point I was cleaning up and saw it and decided to give it another try. I bought a nice sioc8 clip(pelican) this time, hooked it up to the same chip flasher/3volt level converter setup used flashrom and the infernal thing flashed successfully. the cmos had reset and the battery even had a charge after all that time. the system came right up. The moral of the story is that it pays to have a nice mechanical interface. especially if you do not know what you are doing.
