Hi all ... I fee like a noob again. Just got me a head unit for my 2003 Volvo V70 and I cannot find any info anywhere on the device .. I's a new (2 week old) unit purchaced though Amazon.nl but the basic device is as listed below (AIDA64 Report).

It claims to be an A23 system running Android 10, but from the 4 cores, Linux Kernel version and API level, it looks more to me like a pin-compatible A33 (possibly sitting on an A 23 board) and running Android 9 ... AIDA confirmed this.

My problems are that it is stuffed with non-disableable loader and vendor-installed sotftware which are all rubbish, various options (specifically things like Notification Access) are disabled, and the inbuilt loader and software seems to be getting in the way of my being able to run a good launcher and/or choose the right applications to launch. This may also be a hybrid based on a tablet .. I'm not sure ...

Looking for advice/help on how to root this particualt device so that I can at least disable the bloatware, and if possible a nice clean stripped down rom for such a device.

With guideance, I can prtovide any data and/or software from the device. I am current;y requesting an installable ROM from the vendor but I don't think it will happen ... keeping my fingers crossed.

AIDA 64 report in the following post

After doing loads of research I'm even more confused ...

CPU-Z reports the system as an Allwinner A23 ... And then tells me it's a 4 core processor .. the A23 is a 2 core .. but the A33 is pin compatible with the A23 and is a 4 core so is it an A33 masquerading as an A23 .. but there is also another question mark n in the mix ...

Anyone got any advice on how to proceed with this strange crossbreed of a device ?

Will I brick it if I try to root it as the wrong Allwinner device ?
