In Linux, you can try to create boot card of these files for this manual. You need to follow two boot loader entries.
dd if=u-boot.bin.sd.bin of=/dev/mmcblk0 conv=fsync bs=1 count=442
dd if=u-boot.bin.sd.bin of=/dev/mmcblk0 conv=fsync bs=512 skip=1 seek=1

Usually, with such symptoms, the problem with the dtb file, it does not correctly detected network card. Alternatively, you can rebuild the image with the correct dtb. Need any sample dtb file (at least from the firmware, at least from any version of LE\OE) that the network card is correctly recognized and works.
Обычно, при таких симптомах, проблема с dtb файлом, в нём не правильно определена сетевая карта. Как вариант - можно пересобрать образ с правильным dtb. Нужен любой образец dtb файла (хоть из прошивки, хоть от любой версии LE\OE), с которым сетевая карта правильно определяется и работает.
3. You file kernel.img is not needed. This file is intended for other purposes.
4. You have two options. If u-boot in internal memory intact, you can activate a universal-boot and run different systems from external media without changing the pitch. If u-boot does not work, then you can block an appeal to the internal memory and use the boot loader from external SD card to make small changes to the scripts and run the system entirely from external media.
Have you tried to activate the multi-boot ?
1. To capture the image , it is necessary to unpack such program 7zip. If You do not get to unzip, email me, I will upload to the site is not Packed version of the image for recording.
2. Yes, You can try two options - catalog MIII_C or the latest version from the directory MIII_Plus (in latest version added the dtb data from many models in a single file).
3. The file kernel.img need for manual replacement in the same images ( they are not written to the external media). You need to use the images (pokerspace) with the xz extension.
4. If You fail to start LE because of problems with internal memory, you can try to force it to operate Your TV box with external media without the use of internal memory.
I gathered BETA image using the source kernel KSZAQ for the 3.10. Included in the dtb data for multiple devices S812 and S802. Request to the owners of different models S812 and S802 , who have the opportunity to try to run it with the external media. I am interested in the fundamental performance of multivariant dtb data simultaneously for S812 and S802.
All my builds are here to S812. I have only have one model Tronsmart MIII Plus ver 2.2. So I can guarantee the operation only for this model. For all other models - that-be to get a working version, I need feedback from testing. If you are willing to be "Guinea pigs" to test, I'm willing to try to collect the right version. But I warn you, it's not a quick process and requires patience and time.
balbes150: are there Krypton experimental builds around, or can you build one?
Thanks!
The Assembly version with a krypton planned, but I don't have the time to do it.

Hello I bought ((Akaso M8s - S812 - 2G/8G with wifi chip RTL8723BS )) and ihave TWRP and root
my problem Bluetooth does not work as well as Wi-Fi Direct does not work, so i can not cast any think to m8s
>>>>>>>
pleas Can you help me find the firmware: or Backup For the same device with wifi chip RTL8723BS.
Sorry for my weak English.
Maybe need firmware is on the site Amlogic. You were looking for ?
I couldn't get it to boot. tty? error. I then used the dtb.img for my device, no joy
Need to re-activate the multi-boot using the new image (it uses the extended multi-boot).
For those users, who do not work "back" button on the remote control, please try this version of the image.
p/s/ I am only interested in checking the return button. It works in this version or not.
oops... I'm in your official git not seen these changes. These changes in another branch ?
Perhaps the reason is that platforms S905 and S905X different numbers of partitions, which are assigned to the internal and external MMC cards. If you connect the SD card. s905 - get mmcblk1 is external, internal mmcblk0. s905X - on the contrary , external get mmcblk0 and mmcblk1 is internal.
(This step is not needed when you have Android on internal memory) Download Android firmware for your box - you should get it from manufacturer or seller - and extract 2 files: recovery.img and dtb.img to your SD card.
If you change the name of the dtb file for recovery, such as "recovery.dtb" and change the variables in the load script Recovery. Can have both dtb files on an external drive. From LE immediately restart in Recovery mode.
For operation modes, a reboot is necessary to remove from the media (after activation of the multi-download) the file aml_autoscript. When the system reboots and tries to re-use aml_autoscript
Try to check with this user. He wrote that when you run external drives not working, but when installed on internal memory (eMMC) in his work. Set-top boxes You have with him are not the same, but he used m8s+ and it worked. Note that there is a risk to brick and will have to restore it via cable.
These data can be obtained via a special hardware connection (this is an optional USB adapter, which you need to solder wires to the PCB Board). This adapter allows you to show all events from the start (u-boot), TV set-top box and on.
So these options are not suitable for Your equipment. Something to understand at what stage the problem, we need logs output to the console UART.
How to enable universal multiboot we discussed in this thread .... 
message #11 #13 etc
For testing need universal multiboot TV box. I asked about the availability on Your TV box universal multi-boot. By the way, added to the website version of the image with the dtb data from the firmware, the link to which is given edit4ever. Maybe she could work on M8S Plus.
