1. Decompress the file and copy the entire folder of "Lerdge_system" to the TF card or U disk root directory (must be the root directory, or may appear to "cannot find the UI file" problem. If you don't know what is the root directory, please Google it. : ) )
2. Boot, select the TF card or U disk that with the file to upgrade in the "Settings" -> "System" -> "System Update (up arrow icon)".
3. Select the "Lerdge_firmware_v2.0.0 (beta1). Bin" file in the "Firmware" folder, then you can upgrade the firmware.
Note: Do not modify the file name or file path！！！！！
4. The machine parameters will be reset after the firmware updated, and users need to re-set all the machine parameters. So, please backup the parameters in advance, or pre-configure the configuration file for recovery.
When it shows "no find APP!", means updating the firmware fails. The board need to be mandatory updated.
Note: Users must use the TF card for the firmware mandatory updating. U disk cannot achieve that.
1. Rename the firmware file in the the "Lerdge_system" folder to be "Lerdge_firmware_force.bin" after decompressing. And then copy the entire "Lerdge_system" folder to the TF card root directory (must be the root directory).
2. Insert the TF card into the motherboard, reboot, the system will process the mandatory update.
3. Remove the TF card, and delete its root directory "Lerdge_system" folder, to avoid the mandatory update operation again when boot next time.
