  • [S812] MIII Plus 2Gb\16Gb eMMC

    Quote from dtech

    The v3.10-based legacy kernel does not care about dtb.img, it only cares about the one integrated in the kernel.img file. So, it is unnecessary to exchange dtbs under the old kernel, because it will have no effect. In addition, the Meson8* devices cannot boot the OS from an USB drive, so it is worth trying only from an SD card.

    The aml_autoscript under each version also differs, so if you do not use the toothpick method, it is not certain that it will boot. LE10 test versions are not compatible with the old 9.x. So you may have 2GB of RAM, but if you did the toothpick with the LE10, you have to do it again for the 9.x version. (And vice-versa...)

    How much memory does the working LE10 show? (Due to the root squashfs filesystem unpacked into the memory, it will be less, so if there is around 1.5 GB, you actually have 2 GB RAM in your box.)

    The working LE10 shows that I have 1528MB total RAM; I cannot use the toothpick method to boot into the device, whichever way I try doing the toothpick method, it never seems to get into the necessary state; I could try ssh while in the flashed LE on the box, with the sd card plugged in, and then reboot update or reboot recovery to see if that would make a difference.

    I will also try reflashing without replacing dtb.img and see if that will make a difference.

    I will try and report back. Thank you for your help dtech

    I have a hunch that you only have 1GB of RAM in your box, and then these images won't even start.

    Please try this method:

    Hello, thank you for the suggestion, I just reflashed the same build ( LibreELEC-n200-AP6330_2G.arm-9.2.8.8.img.gz ) replacing the .dtb file you linked as: dtb.img and also kernel.img file; still no boot from sd card or usb.

    Now that you mention it, my device is showing as 1528MB total RAM in kodi, also of note, when I was on stock fw, the terminal shell prompt had mentioned 'n200', I suspect that mine is a falsely branded MXIII Plus box (originally I bought it from geekbuying) though most of the other builds specific to MXIII Plus I have been able to boot thus far (except for for the newer ones)

    UPDATE: this method RE: SOLVED: Cannot Install/Update Addons (on LE9.0 and older versions) still works for people running an older build (<9.0) on this box like I am, I am able to connect to and update the LE and kodi repos, however, no third party repos work unfortunately.

    Beyond any of the commands/scripts that sometimes come bundled in community builds for writing to emmc, is there any other way that I can flash a working (i.e. running off of sd card/usb) 9.2+ build onto this box, like using dd via ssh ? I know that may not be ideal and probably risky, but I'm willing to brick this box to find out.

    hello, wondering if anyone is still testing this box (mine is Tronsmart MXIII Plus); i was able to get LibreELEC-S812.arm-9.0-devel-20180718130923-f2dced1-MXIII_Plus.img.gz flashed to emmc / internal with wifi+ethernet working well, however, given the build of kodi is outdated i cannot update any addons (i might try this and report back : RE: SOLVED: Cannot Install/Update Addons (on LE9.0 and older versions) )

    for reference and anyone testing this box out trying to get LE installed to emmc / internal from stock fw :

    - i started from latest stock tronsmart fw, tried many different roms, flashed LibreELEC-ARMv7.arm-10.0-devel-20210507164412-8bd19d9-s8xx.img.gz initially to sd card ( balbes150 )

    - had issues using toothpick method on this box (ultimately ended up running reboot update from terminal emulator while root and while sd card inserted) then was able to launch the flashed LE image successfully which also modified boot going forward to allow boot from sd and usb no problem for subsequent roms

    - could run this image quite nicely although wifi was not detected and i had some issues with noise coming through (noise was largely resolved by toying with audio settings in kodi), addons updated fine

    - could not for the life of me figure out how to flash to emmc successfully for 20210507 build, tried many different variations on LE settings, waited patiently for box to shut itself off etc., also tried installtointernal and emmctool via ssh with no luck (commands not found, i guess not included in these builds), tried to also copy img.gz file in .update folder and reboot with nothing happening (tried this after flashing the first mentioned build in this post to internal emmc successfully; next point)

    - flashed LibreELEC-S812.arm-9.0-devel-20180718130923-f2dced1-MXIII_Plus.img.gz to sd card and was able to successfully create back up (box shut off after about 40min), then restored to emmc (about 25min then shut off), then rebooted via kodi menu with option 'Reboot from instal to EMMC' and LE is now on the box

    other things i've tried :

    - booting other roms : LibreELEC-n200-AP6330_2G.arm-9.2.8.8.img.gz and LibreELEC-MXIII-Plus.arm-9.2.8.8.img.gz respectively to no avail

    - booting chewitt's newer roms LibreELEC-AMLMX.arm-10.85.0-box.img.gz and LibreELEC-AMLMX.arm-10.88.0-box.img.gz where boot just hangs after repartitioning and LE doesn't load (eventually bootloop; also tried using different dtb's to no avail)

    my ultimate goal right now with this box is to have LibreELEC-ARMv7.arm-10.0-devel-20210507164412-8bd19d9-s8xx.img.gz flashed to emmc if anyone has had any success in this (or any other working rom for this box that is 10+); as i can run this rom largely without issue (can figure out what's wrong with wifi later), if anyone has any suggestions or advice please do share

    many thanks to both balbes150 and chewitt for their great work and information in this thread and in many others
