I tested and saw that extFAT does not work 😞. NTFS doesn't even hold out hope for an older kernel.
Well, the fact is that both file systems supported: exFAT and NTFS. Most likely, your box is not able to supply enough current for the HDD, so it won't start at all. But since the factory DC adapter of these boxes is usually 5V/2A, there is nothing strange about this.
Accidentally, I discovered that I can put the system even one SD and a second stake in an external HD (keeping the name and format ext4).
A survey: put backup and format a second partition in FAT32 or extFAT?
It is not really clear to me what and why you want to format. Do not do anything with the data medium on which LibreELEC is installed, because its partition layout is fixed. If you modify a partition on it, LibreELEC will no longer boot properly. However, with other media you actually do what you want.
Before that, coreelec 9.2.x was installed. I got the 2 tvboxes (mxq "all black" and mxqpro4k) the same day, but because you only provide images for the one with s805, I could not leave the other one with android and ce was the only option I had.
Could it be that you have an S905X SoC in your box? Which dtb did you use under CE?
cat /proc/device-tree/amlogic-dt-id
There was not much point in upgrading too, but I gave it a try
And before that, which version was installed that worked?
Anyway, once I am done with le 11, I will try your image again.
If the LE11 will work on your box, there's not really much point in downgrading.
Unable to install XBMC.phyton 3.06 dependency (I think).
Python3 is only available from Kodi v19 (Matrix), only Python2 is available under Leia.
Please look for Leia (v18) compatible addons, because only those will run.
I jsut tried your s905 generic image on my mxqpro4k. It does not boot with any of the 3 relevant dtb files (gxbb_p200_1G_100M.dtb, gxbb_p200_1G_100M_RealtekWiFi.dtb and gxbb_p200_1G_mxq_pro_4k.dtb).
Did you use the toothpick method again? I saw that you tried an LE11 image before, but the new (mainline) and the old (3.14) aml_autoscript are not compatible with each other.
A simple question. What firmware should I download for an MXQ box (m201c) with S805, 1 GB and 10/100 networking?
Obs.: My Thanks to Google Translate.
If by firmware you mean an Android ROM image (either stock or custom), then you are in the wrong forum. If you mean the LibreELEC image, it's not a firmware, just an operating system.
So, If you're looking for the second one, you'll probably need the HD18Q LibreELEC image.
The problem is that no low-level USB functions seem to work at the moment.
Have you tried connecting a different type of USB device (e.g. flash drive) to the OTG cable? Because if that doesn't work either, then we have to check the problem elsewhere.
The interesting thing is that lsusb should also show the USB host chip (or the root hub).
If you unplug the OTG-cable and boot without that (empty first port), is the output still null?
my setup
Unfortunately, I don't have such a device, but are you sure this USB Y-cable with OTG-adapter is suitable for this purpose?
Maybe the middle two USB wires (DATA+/DATA-) are not shared in this Y-splitter (or I don't know, what is this), so I think this will not work.
I think the tuner only gets the power and that's it.
You should try adding a dedicated power supply to the 2nd micro USB port (I mean a real power supply, not a phone charger) and connecting the tuner to the first via OTG.
Hello good afternoon,
I would like to know what is the latest oscam compliancy compatible with K1 Pro S905D, with LibreELEC v9.2.8.7.
and the latest version of Tvheadend for LibreELEC v9.2.8.7.
I have oscam and Tvheadend installed but I can not access via web.
Everything in the repository runs without problems. Are you sure you are trying to access your box on the right IP address and port?
Tvheadend 4.2 and 4.3: http://<IP-of-your-box>:9981
OScam: http://<IP-of-your-box>:8888
Unfortunately, there are problems with the recently published image, so I do not recommend using it for now.
I have sent you a message about how to resolve these issues, please read them.
I have installed this build on mx-iii g and everything works fine. But I have tried to install some docker addons and does not work. Is there something that I have to enable to make it work?
Unfortunately, there is nothing you can do to make it work.
IMPORTANT NOTES - Please read them carefully before asking:
...
- Docker only works under 64-bit SoCs (S905/S905X/S905D), it is not available on 32-bit systems (S802/S805/S812)!
I have the default skin (i dont remember the name i think estuary) The option of power menu that is missing i think its "Reboot from eMMC/NAND"
I modified the affected menu file, please try it:
Index of /misc/shutdown-menu-mod/
So it depends on which theme I will use? But which theme to use so I can add
boot option in power menu ?
In principle, the power menu of each skin can be edited. Mine is also edited, for example:
Which skin are you using?
Hello to everyone. Could you please add a dual boot (or reboot to Android) option to power menu ? There are only power off reboot and exit options
Each Kodi skin uses its own powermenu config, so there's not much point in adding it to Estuary by default, not to mention that this menu item will appear in English on non-English languages as well, which is quite confusing for some users. I don't think you're using the Estuary skin either, because there's no Exit menu item under LE. 
It would be nice to see a dmesg under LE as well. By the way, does lsusb show your tuner?
Do you really own so many devices? :O
*Although my Play 2 is half-dead and my KI Plus is unfortunately completely dead at the moment. 
I assume that the first one is the correct dtb.
If the wifi doesn't work, you need the second one. It differs only in that.
