Can this SOC be overclocked?

This is on wikipedia...

The RK3188 was the first product in the RK31xx series, announced for production in the 2nd quarter of 2013. The RK3188 features a quad-core ARM Cortex-A9 clocked up to 1.6 GHz frequency. It is targeted at tablets and Android TV dongles and boxes, and has been a popular choice for both tablets and other devices requiring good performance.

28 nm HKMG process at GlobalFoundries
Quad-core ARM Cortex-A9, up to 1.6 GHz
512 KB L2 cache
Mali-400 MP4 GPU, up to 600 MHz (typically 533 MHz) supporting OpenGL ES 1.1/2.0, Open G 1.1
High performance dedicated 2D processor
DDR3, DDR3L, LPDDR2 support
Dual-panel display up to 2048x1536 resolution

The RK3188T (PX3) is a lower-clocked version of the RK3188, with the CPU cores running at a maximum speed of 1.4 GHz instead of 1.6 GHz. The Mali-400MP4 GPU is also clocked at a lower speed. As of early 2014, many devices advertised as using a RK3188 with a maximum clock speed of 1.6 GHz actually have a RK3188T with clock speed limited to 1.4 GHz. Operating system ROMs specifically made for the RK3188 may not work correctly with a RK3188T.

I forgot to mention that the PX3 is a 3188T.

Yet your documentation mentions the 28nm process when CPU-Z detects it as a 40nm? Perhaps outdated? Also, even the 3188T is a 1.4ghz, but it is detected as 1.2. What gives?

Also, if you look at my documentation, it is actually detected as an RK3066, so something is not right here.

I did find these two processors:

HiSilicon k3v2 Hi3620 - 1.2ghz quad core

This processor shows up as an RK3188 and RK3066 with the same specifications:

Does anyone know how to hard reset these things? Mine has been stuck on this screen and I cant get it to boot. I have one with the separate box for the brains connected to the screen. There's a reset button, but it only seems to restart and not actually reset anything.

The backup camera still works, but it wont boot anymore.

Any advance on this? To extract the ROM?

Ive never done it myself but it looks like there are a few tutorials online to do so. I wouldn't want anything to break with your tablet so It would likely be easier just to message the seller and say the head unit is messing up and see if they will send you the stock img file.

Hello,
I realize that I didn't purchase my head unit from you but im assuming that you are working for androidautoshop. If you would be able to send me a copy of the 7.1 firmware that would be greatly appreciated. Im interested in testing a few lacking audio aspects from the avin units.
