    Never buy Alfawise tv boxes unless you want hardware and software problems that can't get fixed.
    Why flash another device's firmware to it if you don't have a backup of the current firmware?
    Search for 2 gold dots and short them, if such a thing is not available it will be very hard to get any instructions to enter MaskROM Mode.

      Please I couldn't find any 2 gold dots, what else can I do to make it work ?

            make sure to use firmware that supports AP6255 wifichip or else you will not have working wifi/bluetooth

            as mo123 said, please stay away from alfawise tv box, they suck

              Hi, mAtvXk

              Your guess is correct. I shorted that two pins and successfully put it in MaskROM mode. But still the firmware tool failed at "test device" step, I guess I damaged some parts. I have a UART, can you please point out where might be the pins for GND, TX, and RX? Thank you so much!

                steps to folllow:
                1. open Rockchip Batch Tool and import firmware
                2. short two golden points under NAND chip and keep it shorted
                3. plug the micro USB cable into OGT port
                4. windows should make "add device" sound and device should appear in Batch Tool
                5. unshort golden pins
                6. press Upgrade to start flashing

                  Thank you so much, mAtvXk. I'll post the results when I get a chance to do it.

                    I took some time to try. I think the PINs are correct because there are some texts output on screen. I tried with both minicom and picocom. Here are the outputs:

                    $ sudo picocom -b 1500000 /dev/ttyUSB0
                    picocom v2.2

                    port is : /dev/ttyUSB0
                    flowcontrol : none
                    baudrate is : 1500000
                    parity is : none
                    databits are : 8
                    stopbits are : 1
                    escape is : C-a
                    local echo is : no
                    noinit is : no
                    noreset is : no
                    nolock is : no
                    send_cmd is : sz -vv
                    receive_cmd is : rz -vv -E
                    imap is :
                    omap is :
                    emap is : crcrlf,delbs,

                    Type [C-a] [C-h] to see available commands

                    The bold lines are the output when plug in the device.

                    Seems my device is totally broken? Any idea? Thanks!

                        My UART is CP2102, supports Baud Rates: 300, 600, 1200, 1800, 2400, 4000, 4800, 7200, 9600, 14400, 16000, 19200, 28800, 38400, 51200, 56000, 57600, 64000, 76800, 115200, 128000, 153600, 230400, 250000, 256000, 460800, 500000, 576000, 921600

                        RK3328 supports bit rates 115.2Kbps,460.8Kbps,921.6Kbps,1.5Mbps,3Mbps, 4Mbps

                        I tried a few buad rates, but none worked. Maybe I need a new UART with CP2104?

                          Rockchip = 1500000 baud rate

                          "With some adapters, you may try to connect TX pin of the adapter to RX pin of the board, and RX pin of adapter to TX pin of the board, if you do not get the serial console working."

                          You can also check the UART adapter speeds with CP21xxCustomizationUtility.

                            The first time I opened the customization utility, it shows 1,500,000 at the top two lines. Tried with putty, but it can not open connection to the port (COM3).
                            Then I use the utility to change the "desired" column of the first two lines to 2,000,000. Program device shows green column. But putty still can not open connection to the port.
                            Also tried 1,200,000, can't open connection. Tried 921,600 (and lower baud rates), it opened the connection. But connecting the power to the tv box, it shows some random characters.

                            I guess my UART device only supports up to 921,600, even if programmed to higher baud rates. I ordered UART devices with ch340g and FT232RL, hope they work.
