common problem
1 Did not hear the sound of the beep:
Check the version number is not already the target version number, or check the top SD whether update.cbd
2 normal update short-ming, but my motherboard after a burst of short-ming, began to become long-ming, and can not enter the normal interface
The firmware itself with a test, if the SD data is wrong or SD read data error, update will fail, then just re-insert the SD card, re-power can be. If the test still does not work many times, please try another SD
3 accidentally updated an unwanted version, but not updated on the power, but the original version into the SD card, but can not update, but also can not enter the normal interface
First upgrade the new version of the update, to be completed, then update the old update can be
4 update, the screen display and boot interface are messy, touch screen also seems not working
May be wrong to update the firmware to 2.8-inch 3.5-inch screen, or 3.5-inch screen to update the firmware to the 2.8-inch screen
