Use high-definition to VGA connection CRT computer monitor boot to see, appear Android boot screen into an A31 screen, then no response,
Find all kinds of machines on the network without this model, disassemble watch the mainboard, the main control IC is A31s, the rear panel has a USB interface, an RJ45 network interface, an HDMI high-definition output interface, a single-hole composite audio and video output Socket, an optical audio output interface, 5V power input jack, two antenna posts (actually false, no antenna), the left side of the set top box has two USB and a TF card socket, and the right side has a small ship type power switch. The bottom left side of the front panel is an Android robot and the top is a string of English Smart Media Player. The bottom of the machine has no or no substantive label.
Because I do not know which brand I am, I do not know which firmware to use, I downloaded a generic firmware (A31s_Four Core Alibaba Cloud_Computer Flash Firmware (H version, C version, F version - General_2.1.1-R -20151114.2334), refer to the Forum Brush tutorial line brush, there is no online response, but no other set-top box brush problems, the forum for help did not get results, the back of the STB circuit board is printed TXCZ stickers, so consider whether it is Thai letter box, find no If you think about whether it is a Semino box or not, the search network sees the use of an SD card flashing machine. This set-top box also has a TF card slot. You can try it. Then you download the Temporary Firmware Writer and use an idle 4G SD card to flash the previous code. The downloaded universal firmware was successfully programmed.
Next, I checked the SD card on the set-top box and put it on the brush. After the power was turned on, the blue indicator light went on and off, and the TV screen showed a green progress bar.
I am very happy that after the progress bar has gone, the set-top box enters the off-state, the indicator light goes out, there is no video output, no response for a long time, and I feel a bit panicked. If I am afraid that the brush is broken, I turn off the power and turn it on again. Then I enter the flashing state. , Some worry, and at least not brushed to death, etc. After brushing off, unplug the SD card boot, surprise finally came, you can normally boot into the network settings interface, but no remote control can not operate, so use H9 four The one-in-one and A8 four-in-one remote control tests are all invalid. Trying to use the Zhongjiu remote control did not expect to actually be perfectly usable, but also brushed a firmware that was included in the download burner. It could also be perfectly turned on, but it could not be used in the Nine. Remote controller, had to brush back to the general version of the firmware. The test is perfect.
