Update KODI on Cybertech.

Hello, first of all I'm sorry for my English, I'm Brazilian and I'm using the translator.

Recently I bought a receiver of the brand Cybertech CT-2016, and I ended up doing a reset in it and lost all the information of PVR and the server that cybertech makes available. Unfortunately the company does not offer any support to the device and there is absolutely nothing on the internet about it.

So I wanted to upgrade to Kodi 17 and use IPTV lists (I do not know if you have any other alternative). But the problem is that I do not know how to access android (if any) and I have no idea what img to use to install on the device.
I'll leave the information I have about it:

On the start screen just write MXq and LibreElec and fall directly into KODI. There is no button on the device and the control works only the normal navigation and volume keys.

CPU: ARMv7 Processor rev1 (v7l)
Hardware: Amlogic Meson8B
Video: Mali-450MP
OS: LibreELEC (official) - Version: 7.0.3.1 (kernel: Linux 3.10.99)
Architecture: S805.arm
Kodi version: Kodi 16.1 Git: c327c53
When I go to the update tab there are none in the list.

Does anyone have any idea how I can upgrade? And what alternatives of use for the device?

Grateful.

Hello, since 2 HD18Q versions and an MXQ run well, the problem is that the control did not work on either. I'm going to try m201d now. And the control is the same as that of the MXQ photo. Weird...

Thanks for the help so far.

EDIT: None of the versions. I have seen how to get the control settings in the / system / etc folder. But how do I get it if I can not access android (only system recovery)? I can only connect via Samba on KODI. But it does not have this folder. If I can get the file how do I configure it in the new firmware ( In the case in the rc_keymaps folder?)
