Thank you very much Silver. You are a lifesaver. I was able to get back to life my "MX9 max" tv box ( Rockchip RK3328 4core ARM Cortex A53 64-bit CPU/ 5core ARM Mali-450 GPU/ 2GB RAM/ 16GB ROM), (MINI RK3328_D4, REV:1.0, 2017 09 07)
I used "RTL8723" (rk3328_d4_7.1_rtl8723bs_20180705_r1_root.img) firmware. TV box is rooted and working perfect. WIFI also works.
I have used "{ROM} PoisonATV RK3328" and "a9s_rk3328_d4_rtl8723_20180705_r1(mx9pro ??kodi???)" firmware before. They both installed properly, but after I unplug power, PoisonATV did not boot at all and the other ROM wiped everything and presented the initial setup every time reboot.
Here are my steps to flash the firmware from 'Silver' (rk3328_d4_7.1_rtl8723bs_20180705_r1_root.img) :
- Install Rockchip_DriverAssitant_v4.4 or v4.8
- Open "rkdev tool - AndroidTool_Release_v2.51" and goto 'Upgrade Firmware' tab
- Click 'Firmware' and locate the img file
- Remove screws of the TVbox. Refer to the image attached below and find the copper dots which are necessary to short-circuit to enter MASKROM mode.
- Use a wire or a conductor to connect the two dots. While doing that, connect the male-male USB cable to PC and USB 2 port of the tv box. AndroidTool will show "Found One MASKROM Device" immediately. Remove the Short-circuiting conductor.
- Click 'EraseFlash'
- Click 'Upgrade'
- After the upgrade is finished, remove the USB cable.
- Connect HDMI cable
- Connect power cable (sometimes, you might have to hold the av-reset pin before connecting the power cable. but I didn`t have to do that)
- Boot animation will appear within few seconds. If the display goes to standby mode, remove and replug the power cable.
- the android logo will appear. then wait.....
- Done !!!
- Let me know if this helps.
