At first, it worked just fine. After only few hours of use, when I turn ignition off, android goes to sleep. When I turn ACC back on, touch would not respond. I had to press RST button, to get touch working again.
After five or six reboots like that, android doesn't want to turn on at all. Buttons light up for a sec when I press RST button, but nothing happens, black screen. How can I fix this? The seller sent me the firmware uptade.zip, and MCU (MTCE_CZ_V3,10) img file. What can I do to fix it? So far I tried making a bootable SD card with SD firmware tool, (i tried putting mcu img to sd card and firmware img from this forum) put the SD cart into slot, and powered on the radio. But the screen still stays black, and buttons only flash once when I press RST. Thanks!
