S905 - can't access recovery

  • Hi all, I have an MXQ Pro 4K S905 1GB/8GB from Leelbox. I opened the case to confirm the chip is S905 and that the reset button behind the AV hole is soldered and connected. However, I still cannot use the toothpick method to boot into recovery. Booting via SD Card using various firmwares doesn't work. The AmLogic Burning tool also does not detect the box.

    I think there is something wrong with the firmware and need to flash a new recovery image. The installed Android OS is 5.1.1 and includes the Update and Backup app. Could this be used to flash TWRP or a LibreElec image for S905?

    Thanks,

    EB
