This post is to help you boot into the Android head unit into the Android Recovery partition when you have a working Android operating system and your Android is rooted. It is important to note that this procedure to boot into recovery mode relies on a working Android and a rooted system. Luckily most Android headunits are rooted, so this is well worth a try to get into recovery mode.
Nonbooting Android
You need this article if your Android system will not boot and you seek Android Recovery.
Android Boots needs recovery.
A properly booting Android operating system can take much of the guesswork out of getting into Android Recovery mode. If you can either get apps from the Play Store or at least side-load the .apks, entering the boot partition and activating recovery mode should be possible.
android Recovery options
You get some neat tools in aAndroidrecovery for your aAndroidheadunit. Later models are much easier to use with touch screens being available, making the use more like Android, whereas old versions rely on random or obscure button taps to navigate the menus.

Need ROOT
As with all the fun things, root privileged for the super cow power apps to run in. If you don’t have a root, you are probably looking for Recovery mode to find it. This is a bit of a catch-22 for you and maybe a dead end. Keep trying, though.

Enter recovery (working Android)
A shortcut to getting into Android recovery mode via a working Android app on the play store. Plenty of apps can help you; this one – reboot options is used in this demo.
Install the app, open the app, and choose ‘Recovery.’

If you get warnings about root and when you press OK to boot into recovery, a ‘Sorry your phone is not rooted’ message, you can assume your headunit is not rooted. You can try some other apps for a reboot, but they all need root to reboot into Recovery mode.
Suppose you have now rebooted into recovery mode, and well done!
If you have not booted into recovery mode, probably due to a lack of root, you need the instructions for the ‘no Android recovery mode.
Terminal emulator
If you have a terminal in your rooted Android issue, this command reboots in recovery mode.
