Device skyworth

Hi

My box skyworth cyborg001, is it supported to install coreelec

Hi Simon,
specs look OK, so if the BL isn’t locked, it should work. Just give it a try.
DTBs to try (depends if your LAN is 100M or 1G):

  • g12a_s905x2_2g
  • g12a_s905x2_2g_1gbit

Edit: Is this your Box? Pure OTT Streaming Box
Then it will get difficult to impossible to run CE on it.
Box is L1 certified, therefore BL will be locked.
There is also no switch to boot from SDcard…

HP40A , this box locks bootlooader , moreover skyworth they have Modified uboot , won’t be able to boot coreELEC . , HP40A same mecool km2 ( skyworth)

The box looks very similar to Skyworth’s another product HY40A/HY4001, and a user reported in EmuELEC discord that his HY40A could boot EmuELEC with Android 9 firmware but can’t boot it now with Android 10 firmware, hence it’s not locked with stock Android 9, even with Widevine L1.

So you can try your luck downgrading the firmware first. The stock Android 9 without any update could be your best choice.

Hi I am glad to see this thread
This device sold under five different names and a different combination of I/O’s
1 - contain a SD card one USB 3 and one USB 2
2 - contains only one USB 3 and one USB 2.
3 - contains only a USB 3 port and an internal SSD memory
Please join to break Block on this device
I will support and experiment on the version available in my hand ,

Please help to make it happens

this is the debug info
i have bluged usb card created by amlogic card creator to make it more clear
