One last question, making tests I have tried both Armbian_23.11.1_Aml-s9xx-box_bookworm_current_6.1.63_xfce_desktop.img and Armbian_community_25.2.0-trunk.86_Aml-s9xx-box_bookworm_current_6.6.63_xfce_desktop.img I think that it is more stable for me the 23.11.1 version. I have been trying to find and archive repository to find any version between these two, but I haven't get managed. is there any problem using one year ago version? I am not sure but I also think that 25.2.0 is not an stable release.Is it enougth using armbian-config or apt upgrade systems? Thanks a lot.

Hi, I have redone again all (flash sd, install to emmc, upgrade, ....) everything goes perfect if I use this config in extlinux.conf before any upgrade. FDT /juan/meson-gxl-s905x-minimxiii-ii.dtb Create the juan folder and put there the dtb file. Thanks a lot @SteeMan

Hi, it has solved the problem. I am going to make again all process to check if this way there will be no problem and I will publish here the results. Thanks a lot.

Thanks, I have hello of my brother. And by my own I managed to get all the hardware off my TV box working by doing lot of test with dtb files. I have this last step problem. How to keep the TV box updated. You can see my other posts (like a serie of them: first how to backup emmc of android TV box, how to use and edit dtb file, ...) I hope someone could help me and I will write afterwards all the steps. Merry be it is very easy to "re-configure again" the boot process after apt upgrade and before the final reboot. This way, this post will be useful for some people, won't it? Thanks a lot. I will read also your links

Hi, i have tried and ...same problem First question is about (I am newbie in Linux) kernel. It seems that it has not been updated And the second question is that again, after reboot, the TV box doesn't boot. (See images, of before, after and failed boot) There is a packet that it is changing something. What will be the solution? 1. Before reboot, go to this file and change this ? 2. You must prepare again the SD card with the official IMG and reflash again emmc. (This is a big problem because I will lost what I have in my actual TV box everytime I want to update/upgrade). Any key ? Thanks a lot.

Thanks I will try and inform here for future users.

Hi, I own a Mini Mx III - II (S905X) that I "flashed" with an micro SD with install script. The tv box without any micro sd card inserted boot perfectly afterwards. I keep it but today, after few months I see that I have this image installed: Bookworm 23.11.1 Armbian_23.11.1_Aml-s9xx-box_bookworm_current_6.1.63_xfce_desktop.img.xz I have seen now that we have this version: 25.2.0 Armbian_community_25.2.0-trunk.86_Aml-s9xx-box_bookworm_current_6.6.63_xfce_desktop.img So I have tried to use armbian-config system firwmare update to get up to 25.2.0. After waiting to download and installa packages, I reboot my tv box but .... it doesnt boot properly. It says: "Failed to mount /dev/mmcblk1p1 as root file system" I am lucky as I keep the original micro SD card, so I have inserted it again and run again the install script, so now, again, I have 23.11.1 armbian booting perfectly in my tv box without any sd card. The question is .... 1. what have done armbian-config update to break this? 2. is the only way to keep my armbian OS up to last update by flashing again the new img file to sd card and make again the installation to my emmc of my tv box? 3. is there any other way not to loose all data to update to last updates? Thanks a lot,

Hi, I have finally installed armbian in my amlogic. I want to make a backup of the emmc now that it is "just installed". So if next year or whatever, if i want to go to my first day after the installation, I could go quickly. What will be the best way to create a "rescure image usb" ? In case of a disaster, could I boot from usb or only from sd? Thanks

Or I dont know or it doesnt work

Hi, finally I have get managed to get something good, and i want to share here to community. Finally I have decompile and compile lots of dtb files, dts files from here from librelec, .... changing text lines in dts files one by one to check them.... Finally: Based from meson-gxl-s905x-khadas-vim.dtb Decompile and make these changes: Lines 329-330, put this (solve BT): compatible = "qcom,qca9377-bt"; enable-gpios = <0x15 0x60 0x00>; Line 353, put this (solve LED): status = "disabled"; Line 1597, put this (solve USB): dr_mode = "host"; WORKS: usb1, usb2, hdmi, lan, wifi, BT, led, poweroff, poweron IR, audio DOESN'T WORK: poweroff IR I have even tried wifi hotspot (works). I attach here these two files: meson-gxl-s905x-minimxiii-ii.dtb meson-gxl-s905x-minimxiii-ii.dts Thanks a lot for your help. Next step .... install to emmc !!!! Next step meson-gxl-s905x-minimxiii-ii.dtb meson-gxl-s905x-minimxiii-ii.dts

HI, I have just used this firmware: Armbian_23.11.1_Aml-s9xx-box_bookworm_current_6.1.63_xfce_desktop.img.xz (https://forum.armbian.com/topic/17106-installation-instructions-for-tv-boxes-with-amlogic-cpus that links to: https://es.sbcmirror.org/dl/aml-s9xx-box/archive/) Is it a "full" one? Where are full ones?. About opening the box, yes, I opened it some days ago. May be you can identify something here. LMT8830 ? Wifi+BT (it is also strange that wifi works and bluetooth doesnt, isn't it?) (google search: https://github.com/armbian/firmware/commit/2516660cc89cc130c1e675fddfeb0b695acbdc76) But I don't know how to "write" or "search" for the correct DTB file. Is it impossible to get from android firmware in my tv box by a terminal app? Thanks a lot for your help. I am near, but next steps are impossible for me.

Hi, I have spent several days compiling and decompiling dtb and dts files. Trying to find the better one, comparing dts files in text editors.... Finally I have found something better but yet, not the best. (I have even checked libreelec dtb files) I have also tried to check in Android TV Box by installing terminal or hardware info apps trying to find information about bluetooth. But no luck. I have seen P212 in my android tv box. At this moment, my conclusion is: 1. despite my android tv box "says" P212, i found better this dtb file meson-gxl-s905x-khadas-vim.dtb than this one: meson-gxl-s905x-p212.dtb. 2. Both have errors, but after comparing lots of dts files if I make TWO changes in meson-gxl-s905x-khadas-vim.dts file, I get managed to get working all of this: usb1, usb2, hdmi, lan, wifi, LED, poweroff, poweron with IR, audio. And DON'T work: bluetooth and poweroff with IR dts line 353 change to "disabled" (solve LED problem, so I can see led on and off) dts line 1597 change to "host" (solve that with meson-gxl-s905x-khadas-vim.dtb only one usb port works. Now the two usb ports work) I have "left" two problems with my modified meson-gxl-s905x-khadas-vim.dtb. 1. I haven't got bluetooth working (THIS IS IMPORTANT if I want to use it for home assistant for example) 2. I haven't got the chance to power off the tv box with IR remote control (THIS DOESNT MATTER) Questions, please: 1. Despite my android tv box shows me "P212" in some "play store hardware info apps".... is there any problem not to use meson-gxl-s905x-p212.dtb and use meson-gxl-s905x-khadas-vim.dtb ? 2. Is it dangerous to alter two lines in a dts file? could I damaged hardware? 3. I have also tried to connecto TWO external old usb bluetooth adapters to solve the biggest problem of my modified dtb file. Both have the "same problem". I can see my tv box with armbian firmware from my mobile phone, but my armbian tv box can NOT detect anything. I click on "search" but .... nothing. 4. I have tried also to modified a bit the dts file with these two options to get the INTERNAL bluetooth working: compatible = "brcm,bcm43438-bt"; or compatible = "realtek,rtl8723bs-bt"; (line 329, and with realtek option also add in line 324 this: enable-gpios = <0x15 0x60 0x00>;) do you know how could I find the bluetooth chipset in a rooted android tv box? I can not find any solution with compatible = "brcm,bcm43438-bt" I get this: root@aml-s9xx-box:~# dmesg | grep Bluetooth [ 9.041277] Bluetooth: Core ver 2.22 [ 9.064960] Bluetooth: HCI device and connection manager initialized [ 9.064985] Bluetooth: HCI socket layer initialized [ 9.064992] Bluetooth: L2CAP socket layer initialized [ 9.073711] Bluetooth: SCO socket layer initialized [ 9.161291] Bluetooth: HCI UART driver ver 2.3 [ 9.165629] Bluetooth: HCI UART protocol H4 registered [ 9.170024] Bluetooth: HCI UART protocol BCSP registered [ 9.174866] Bluetooth: HCI UART protocol LL registered [ 9.179849] Bluetooth: HCI UART protocol ATH3K registered [ 9.185282] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 9.191661] Bluetooth: HCI UART protocol Intel registered [ 9.197142] Bluetooth: HCI UART protocol Broadcom registered [ 9.201468] Bluetooth: HCI UART protocol QCA registered [ 9.209641] Bluetooth: HCI UART protocol AG6XX registered [ 9.251766] Bluetooth: HCI UART protocol Marvell registered [ 9.459255] Bluetooth: hci0: BCM: failed to write update baudrate (-56) [ 9.464465] Bluetooth: hci0: Failed to set baudrate [ 9.650023] Bluetooth: hci0: BCM: Read verbose config info failed (-56) [ 22.006738] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 22.006787] Bluetooth: BNEP filters: protocol multicast [ 22.011685] Bluetooth: BNEP socket layer initialized root@aml-s9xx-box:~# rfkill ID TYPE DEVICE SOFT HARD 0 bluetooth hci0 unblocked unblocked 1 wlan phy0 unblocked unblocked It seems that the problem is "failed to write update baudrate". 3. with compatible = "realtek,rtl8723bs-bt"; I get this: root@aml-s9xx-box:~# dmesg | grep Bluetooth [ 8.236291] Bluetooth: Core ver 2.22 [ 8.251409] Bluetooth: HCI device and connection manager initialized [ 8.251434] Bluetooth: HCI socket layer initialized [ 8.251441] Bluetooth: L2CAP socket layer initialized [ 8.251483] Bluetooth: SCO socket layer initialized [ 8.312137] Bluetooth: HCI UART driver ver 2.3 [ 8.312193] Bluetooth: HCI UART protocol H4 registered [ 8.316137] Bluetooth: HCI UART protocol BCSP registered [ 8.321480] Bluetooth: HCI UART protocol LL registered [ 8.333958] Bluetooth: HCI UART protocol ATH3K registered [ 8.334060] Bluetooth: HCI UART protocol Three-wire (H5) registered [ 8.334569] Bluetooth: HCI UART protocol Intel registered [ 8.351967] Bluetooth: HCI UART protocol Broadcom registered [ 8.364945] Bluetooth: HCI UART protocol QCA registered [ 8.370309] Bluetooth: HCI UART protocol AG6XX registered [ 8.387307] Bluetooth: HCI UART protocol Marvell registered [ 21.398088] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 21.398110] Bluetooth: BNEP filters: protocol multicast [ 21.398127] Bluetooth: BNEP socket layer initialized root@aml-s9xx-box:~# rfkill ID TYPE DEVICE SOFT HARD 0 wlan phy0 unblocked unblocked No errors, but.... no info in rfkill output Does anybody know how to go further here? Any dts/dtb expert? I can not get the internal bluetooth module working despite it is being "detected". I can not also get the two external usb adapters working because then can not find anything.... NOTE: I will upload my final DTS and DTB files but I want not to upload a not-finished file.
