Power off system issue, KIII PRO just reboot

salvo · 9 July 2018 22:00

I am having issues with unit power down while using LibreELEC 8.2.2.3 or CoreELEC 8.90.4. I am getting restarts in both system (power off system through KODI), it never shut down unit properly to green LED, always blue LED. Also when used shutdown via SSH, same result = just restart. However when I take out SD card and boot to Android “VITMOD 5.0”, shutdown works fine (unit goes to green LED).

I have KIII PRO unit, S912, 3G/16G, I used DTB image “gxm_q200_k3_pro”

Could be parallel system (VITMOD) reason for restarts when it suppose to shut down? Bootloader is 7.1.2 (see attached picture) rather than stock one 7.1.1

Thanks for help

I had to try this on my KIII pro, using the same .dtb and 8.90.4. I must admit I’ve never seen a green led however I don’t usually shutdown my unit and I’ve never used android on it.

Mine seems to go from blue led to red led when shutting down via the menu in Kodi. Does it indicate standby?

salvo · 10 July 2018 15:52

Hi Rascal, I am very sorry, it is red led (not green led).

Using coreelec or even libreelec I can not get red led (standby) mode working, it could be related somehow to paralel system (android or maybe 7.1.2 bootloader or so).

Thanks to let me know that KIII PRO does shutdown to standby when correctly configured.

I will wait for bumerc if there is anything strange on my box…

Rascal · 10 July 2018 16:46

No problem, I do also have android on the internal and I’m running CoreELEC from SD if that makes any difference.

Not directly related to your problem but I had alot of issues with reboot from every CoreELEC version up until 8.90.3. On reboot my box would sometimes either shut down, get stuck at black screen or at mecool logo.

On 8.90.4 something changed and I don’t think a single reboot failed since, athough I don’t reboot often.

Good to know…

I am about to just install CoreELEC and delete any android. The best I assume is to keep just CoreELEC and no android at all. Install CoreELEC to unit flash as one and the only system.

bumerc · 11 July 2018 07:13

Hi,
it shows u-boot (Bootloader) environment -> commands and variables for controlling the boot process.

You are using a modified Android system, apparently the author of this build has integrated a multiboot option.

Install original Android OS and try again

salvo · 11 July 2018 16:05

It is working now, it was really related to Android system and dual boot (VITMOD android 7.1.2 together with NEUTRINO).

When I revert back to original stock firmware 7.1.1 from Sep, shutdown works just fine with Red LED when you power off system from KODI.

Thanks bumerc
