I received my HK1 RBOX X4 yesterday and CE 21 is perfectly stable. I’m very happy with it.
I decided to run CE on the eMMC in (no dual boot support for this device) in hopes of later running Android from SD/USB because I only really need it for SmartTube and Twitch.
Unfortunately, that doesn’t seem to be possible, so that’s my mistake. So I was looking at HybridELEC as a possible solution or really just running stock firmware on eMMC and then a fast, small USB to run CE.
Unfortunately, no version of USB Burning Tool will recognize my device. I’ve tried them all. I’ve also tried Bootcard maker with original firmware, HybridELEC and even a SlimTVBox image.
It’s refusing to boot from the SD card now, so recovering the original firmware seems impossible.
Is there any way I can force boot from SD with CE on my eMMC already?
The only thing I haven’t tried yet is cracking it open and shorting the eMMC. But even then, I don’t know how I would get a recovery flash working.
Edit: I’m stupid.
Calling ceemmc -x again will remove the internal installation and make the player flashable again. I was then able to toss HybridELEC on it easily (Vontar X4 image) and now have triple boot working.
