Hi, I have a brick in 7022 and already bought it so. The previous owner told me he stopped at a update and removed the cable. When you restart it no longer called or recognized via USB (fwdn) I am a Linux User, so I tried several ways a recognition via USB making the procedure to disassemble, remove the cable from the LCD and battery followed by short between pin 7 and 8 of nand as I did on my old 7015 did not work . In the Linux terminal command lsusb no device is detected. My intention was to make the service via VirtualBox with Windows XP the same way I did in my old 7015. To rule out problems with the computer I also tried on another computer with WindowsXP system and did not work. Absolutely not recognize the device via USB. The current situation is as follows: The hardware is operating, because we have all the tensions of the board at the time the power is pressed (1.8volts, 3.3volts and 5volts). The system is not booted by not having completed the update to the previous owner tried to do when he was bricked I can not complete the update because there is no recognition by the USB port. Then I ask. Is there another way to write the firmware for this device without USB? Is there another way to force recognition by USB? For the short between pins 7 and 8 of nand had no effect. Please any help is welcome and sorry for my bad english! Thanks!
