Coreelec on MyGica ATV 495X-B (Amlogic S905X-B)

You should get yourself a decent SD Card with fast read write speeds. I’m guessing that 2gb SD Card is not. Samsung Evo Plus 32gb is my preferred sd card.

@ Poida : Well-noted. I am leaving then Coreelec installed on the SD card as is.

@ Kostaman: Considering the low cost of SD cards nowadays, I purchased a 32GB Kingston Canvas Go micro SD card (90MB/sec Read & 45MB/sec Write) for £8 …

I figured out the issue with IR remote too. The guide in the forum was really accurate.

Thanks

Hi - how did you do that i.e. the process that made renaming the aml_autoscript to factory_update_param.ubt work? I am doing as below:

  1. Burned the Coreleelc 9.0.1 download on to a USB using Rufus
  2. Copied the relevant dtb file from the device tree folder and pasted in the USB root and then renamed it to dtb.img
  3. Made a copy of the aml_autoscript to factory_update …
  4. Inserted the USB into the device and powered it on with the reset button pressed
  5. I release the reset button when the device logo appears on the screen

But that’s where I am stuck. It does not move past this screen. I have tried different device tree dtbs. It seems my device is locked somehow and does not want to boot into Coreelec software. Could you please share some thoughts on how to possibly fix it? Thank you!

Please use a current stable release.
9.0.1 was released decades ago and may contain some serious bugs.
Since today we are at 9.2.4.

Thank you for responding to my post. Your comments have helped me in that I managed to revive an older Tanix TX3 Mini box with the latest 9.2.4 CE image. I tried several previous versions of CE on the same TX3 Mini box without luck. It’s running now via USB and the performance is not too bad. Ideally I would like to install to the internal memory and I tried, “installtointernal” command via SSH but it didn’t work saying something like the file system is not recogonised or found etc. Could you or someone here please share some hack that I can try to overcome this issue?

My original issue is still there i.e. I am unable to install CE on to my X96 Mini box. I have tried all sorts of different CE / LE versions with a number of different dtb files but it just won’t boot. I have been reading a few posts on different forums and it seems either my box is fake with some chipset / hardware configuration that is not supported by any of the dtbs or it’s dual boot locked - not sure what that means and how to unlock it.

installtointernal is not officially supported.
Newer devices can use ceemmc, which is actively developed and supported.
Unfortunately it isn’t working on your device.

CE on X96 Mini is being used by some users here and should work flawless.
Please try it with gxl_p281_1g.dtb or gxl_p281_2g.dtb (depending on the RAM being used in your device).
Also take a look at the following thread:

I’ve been trying both and more but it does not want to boot. I have a similar X96 mini that I bought a while ago and that works flawlessly. This particular box is either locked by the vendor somehow, has a different hardware than it’s showing, or something else. The Android boots up fine and works as per normal. Some posts suggest that maybe it’s a Rockchip box - but not sure how to confirm that and then find the suitable dtb for it.

I’ve also tried to update the firmware to see if the new firmware unlocks it somehow but cannot even update the firmware. Getting the attached screenshot messages.

According to your second screenshot, it is indeed an Amlogic device (p281), so the dtb suggested before should be the right one. Which CE image did you download?

You said, that you also tried to install LE on this box.
Afaik the LE installation automatically modifies the bootloader during the first boot, so the device is unable to boot CE afterwards until you recovered it with a stock Android image from the box vendor.
Please take a look here:

I downloaded the latest CE version i.e. 9.2.4. I tried LE but that didn’t boot either so I don’t believe the original bootloader has been modified. I have tried to install the stock Android image but as per the screenshots shared, it’s giving errors saying the signature cannot be verified etc.

Use Amlogic Burning Tool

I did not use the USB Burning tool and instead used the Burn Card Maker. It did allow me to flash the firmware but I still cannot boot the CE using gxl_281_1g or gxl_281_2g dtb files. It just does not want to boot. It looks like it’s coming down to using the correct dtb file. I’ll try a few more to see any of them work.

It is the right dtb for sure.
But you didn‘t answer which image you used and only mentioned the version. It‘s important to use the non-ng version.

Sorry I did not think that way. I used the CoreELEC-Amlogic.arm-9.2.4-Generic.img.gz.

Did you only try to boot from USB or also from uSD card?

I have tried both. I format the SD card with SD Card Formatter then burn the image on to it using the latest version of Rufus. I put the card in the SD car slot and power it on. I have tried the toothpick method as well but my understanding is the Amlogic devices’ boot sequence is, first SD, second USB, and then internal flash.

I think the initial toothpick method is needed for all TV boxes to boot from uSD/USB.
But if you also tried it, I’m out of ideas. Maybe the bootloader is indeed locked.

Amlogic Burning Tool with an Android Image for your box specs.

Thanks guys - you have been helpful but I am not able to resolve it so going to leave it here. In the future I managed to work it out, I’ll share my learning here!
