Is it possible to flash FreeBSD onto a Trekstor Breeze 10.1 Quad Tablet?

[cabriofahrer]

I have a Trekstor Breeze 10.1 Quad Tablet, which after years of not using it is not capable of signing into a Google account (Android 4.x) anymore. Anyway, I did a factory reset and now I do not even get passed to connecting that thing to my wifi network and therefore to a usable GUI, because it wants to download updates from Google which is not possible without connection. So it is completely useless right now. I think the SoC is a MT8127. In the manual it says under "Supported operating systems" "Linux®, Mac OS® (from OS X 10.6), Windows®, (Windows 8, 7, Vista®, XP", which I think is very strange. I have not found any information on the internet regarding this device running with any of the mentioned operating systems.
Has anybody here ever have come across a tablet like this and seen it running with any other than Android? Would it even be possible to flash a 32-bit arm image of FreeBSD onto it?

The support is for the software to connect/sync to/from the device. Not what you can run on the device itself.

No we do not have support for any MediaTek Arm CPU that I know of.

An Android target is even harder to convert than Linux. Usually the bootloader is in SPI Flash and blanking it can mean shorting out the SPI bus to ignore the SPI Flash device on bootup.
Sometimes there is a recovery button you must manipulate.

You would need a u-boot board profile and UART pins on the device. (Usually requiring soldering because they are unpopulated.)

I think the best chance is some RK3399 All in One" devices or Tablets.
I bought the ELO ESY10i1 which is AIO and it uses RK3399 but I can't break out of Android. MicroSD card prepared with u-boot but it is ignored...
This is before I can even tell if SCREEN will work at all with FreeBSD. All my successful Android conversions have been with UART debug.

Anything with a built-in screen just adds more complexity to the hacking. There are so many video formats used. eDP, HDMI, LVDS, ect..
Devices with screens tend to use internal connection protocols. eDP or MIPI DSI.

Most Arm Platforms do not have Plug and Play. So little things like video output are more complex. You must declare all devices in a Deice Tree.

Thank you for your responses. Well, then that device is completely useless now. This is also generally speaking for all smartphones and other tablets after a while, when the version of Android cannot even be upgraded to be able to install certain apps or in this case, log into your google account anymore.
