  1. H20 Pro RK3528 M16-R6B-L3-V1.0 bricked after writing U-Boot to eMMC - need Maskrom pins

    himigs posted a topic in Rockchip CPU Boxes
    Hi, I need help identifying the Maskrom/eMMC short points for an RK3528 TV box. Device: - TV box sold as H20 Pro - SoC confirmed as Rockchip RK3528 - Board marking: M16-R6B-L3-V1.0-260121 - RAM detected in Linux: 963 MiB - eMMC detected in Linux: 7.83 GB / 7.30 GiB - eMMC name from Linux: P1J95K - eMMC CID: fe014e50314a39354b12739109744200 What happened: - The box originally booted Android from eMMC. - Armbian booted successfully from SD using a customized joilg/x88pro-based image. - Later I wrote U-Boot/idbloader to eMMC: - idbloader.img at sector 64 - u-boot.itb at sector 16384 - After reboot, the board no longer boots from SD or eMMC. - LED stays red. - No HDMI output. - No Ethernet link/activity. - RKDevTool on Windows shows "No Devices Found". Recovery attempts: - Tried the reset/recovery button behind the AV/P2 jack while connecting power and USB. - Tried both USB ports. - Tried RKDevTool v2.86 with Rockchip drivers installed. - No Loader or Maskrom device appears. - Tried UART pads marked GND/TX/RX using ESP32-C3 as bridge, but output is not readable. Question: Can anyone identify the eMMC Maskrom short point for this board? I need to force RK3528 into Maskrom mode so I can restore the first bootloader area of the eMMC. Attached photos: - Front of board - Back of board - Macro photo of the eMMC/storage chip area - Macro photo of test pads near the storage chip
