    How about you try paperclip method again and use RockChip Factory Tool (try 1.45e or older)

    I got a new UART which got some meaningful output:

    Code:
    DDR version 1.16 20190528
    ID:0xFFF
    ln
    DDR3
    333MHz
    rd addr 0x80000000 = 0xC9D2000F
    rd addr 0x40000000 = 0x40D200FF
    rd addr 0x20000000 = 0x20D200FF
    rd addr 0x10000000 = 0x10D200FF
    rd addr 0x200000 = 0xF2001D
    rd addr 0x100000 = 0xD200FF
    rd addr 0x80000 = 0xDA00FF
    rd addr 0x40000 = 0xD600FF
    rd addr 0x20000 = 0xD200FF
    rd addr 0x10000 = 0xD300FF
    rd addr 0x8000 = 0xD280FF
    rd addr 0x4000 = 0xD240FF
    ERR

    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.

    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?

    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

    Terminal ready
    h\mkjOdw`GfGe'O\beyO#omh]Cd?`;G'mh]Cd`;G'.mh]Cd?`;G'mh]Cd`;G'h;~



    ============= minicom


    Welcome to minicom 2.7.1

    OPTIONS: I18n
    Compiled on Aug 13 2017, 15:25:34.
    Port /dev/ttyUSB0, 00:43:50

    Press CTRL-A Z for help on special keys

    h\mKjodW`9Gfge'_O\?beyO#o.mh]Cd?`d?h]Cd`d;v


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

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

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

    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

    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!

    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

    PLEASE HELP
    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.
