Help with Mecool k1 Plus

    How to get these files?

    u-boot.bin.usb.bl2

    u-boot.bin.usb.tpl

    u-boot.bin.usb.bl2 = DDR.USB

    u-boot.bin.usb.tpl = UBOOT.USB


    Unpack the aml_upgrade_package.img that I sent you and search for these files in the output directory

    ~$ '/media/jaroslaw/30BAD20DBAD1CF88/utils/aml-flash-tool/tools/linux-x86/update' write '/media/jaroslaw/30BAD20DBAD1CF88/utils/UBOOT.USB' 0x200c000

    ERR: write data to device failed


    I don't know what to do with it. The same error all the time.

    What happens when you run the “update identify” command? You then have to initialize the RAM memory before you can write TPL to it.

    What happens when you run the “update run d9000000” command to initialize the RAM memory?

    Here you have already initialized RAM. In this step, instead of DDR.USB, load the TPL UBOOT.USB to the address described above


    Code
    media/jaroslaw/30BAD20DBAD1CF88/utils/aml-flash-tool/tools/linux-x86/update write media/jaroslaw/30BAD20DBAD1CF88/utils/aml-flash-tool/tools/linux-x86/UBOOT.USB 0x200c000

    then

    Code
    update write ..yourpath../gxl/usbbl2runpara_runfipimg.bin 0xd900c000
update run 0xd9000000

    [email protected]:~$ '/media/jaroslaw/30BAD20DBAD1CF88/utils/aml-flash-tool/tools/linux-x86/update' cwr '/media/jaroslaw/30BAD20DBAD1CF88/utils/aml-flash-tool/tools/linux-x86/DDR.USB' 0xd9000000

    My guess is that you have a clone device and it is a gxbb (s905) platform, that would explain the PLL error. I'll send you gxbb blobs, well worth a try…

    I don’t want to have a say, but you could try it with the image I made in the same way. (Extract the content with the customization tool.)

    In the meantime, we managed to unbrick the KI Plus S905D (1G/8G) in the background with @creited.
    The vendor never released a factory image (only an OTA update was released), so it was impossible to repair the bricked devices so far.

    I was able to create an image, close to the factory ROM state, that could be used with the USB burning tool:
    KI_PLUS_S905D_v4_OTA-REPACK-20180815 — Yandex.Disk

    I only dare to suggest this because the same model of device has already been revived with it.

    I had extracted the necessary files from this image and tried to upload as well
