In many cases, the user often chooses to upgrade or flash the TV system in order to make his own Changhong TV more functional. However, such operations are often accompanied by some risks. So how to operate in order to safely upgrade the system? Xiaobian introduced how to upgrade the system by entering the factory mode.
1, first enter the factory mode, view the TV software version information;
How to enter the factory mode of Changhong Smart TV:
The first one: press the remote control “menu†button, and then the left side of the TV will come out of the menu bar, this time do not press other keys, press the number keys 0, 8, 1 , 6 then, then, enter the factory mode It
Second: TV UI interface is a single interface or left and right switching interface: press the "toolbox" key or press the "menu" button in the interface of the HDMI signal source, to the "Information Center" option, this time the remote control presses the number Keys 0, 8, 1, 6 There is no numeric keypad by pressing the virtual keypad numbers 0, 8, 1, and 6, so that the factory mode is entered;
2, find the corresponding TV upgrade package in the relevant forum or on the network, enter the download;
The name of the upgrade package is the same as the name of the software version in the corresponding factory mode.
3, after the download is complete, unzip it. After decompression, the files in the archive are generally divided into four types:
1) Decompression results in two (T8 M8) +bin files with the suffix pkg:
Check TV version T8 or M8, and then correspond to the TV version. Delete T8 or M8 that does not match TV. Do not move the bin file. Then put these files in the root directory of the U disk;
2) Decompression results in two (T8 M8) files with the pkg extension:
Check the TV version T8 or M8, and then for the TV version, delete the T8 or M8 that does not match the TV. Then put these files in the root directory of the U disk;
3) Decompression to get a pkg file + zip file:
Do not delete files, put these files in the U disk root directory;
4) Decompression to get a file for pkg:
Do not delete files, put these files in the U disk root directory;
4, copy the file to the U disk or SD card root directory (U disk is best formatted once, must be made FAT32 format), after the copy is completed, the U disk is inserted into the USB port of the TV has been turned off, boot;
5, the TV screen shows "in the system upgrade, do not power off" and other tips, and then continue for 2-3 minutes after the TV will automatically restart 1-2 times. Accumulative about 5 minutes, the upgrade is complete, the TV automatically restarts, the new version begins;
