Android Recovery reset for Head Unit with no buttons.

Your Android headunit won’t boot into Android, and you think the solution can be found in Android Recovery. This article can help guide you to accessing the Android Headunit recovery partition, which can help solve some Android boot loop problems.

Is it still booting and rooted?

If your Android already boots and you have root privilege, there are easier ways to get your head unit into Android recovery.

No Boot, No Buttons

It can seem impossible if you have a nonbooting Android headunit and want to access the recovery menu. The guides tell you to press the volume buttons or tap the power button, but what if there are no buttons?

Luckily, one tiny and sometimes very well-hidden button on the Android headunit can be used. The name of this almost secret button on some Android headunits does not relate to its use for Android recovery. But what is the secret Android recovery route when there are no physical buttons?

RST – Reset button

For Android headunits that don’t have physical buttons, the RST button is the key to communicating your commands. This RST button is well known as a reset button, and you may have already used the button as a reset, but it can do more.

This is where it gets very confusing. With so many different Android headunits produced over the years, the options for Android recovery via the RST button have grown. There is no one solution, and there are many potential solutions. Some aim at the older 8227L DEMO ALPS, while others target the PX5 and PX6 Android headunits.
