All computer systems in the world have a way to access them when normal procedures fail or just a way to do tasks that are not readily available on the Interface. These modes are known as system maintenance modes. Android is no exception.
The android recovery mode
The android recovery mode is a bootable partition that has the recovery console installed. All android devices come with Google’s recovery environment which is known as the ‘stock recovery’.Seeing that Android is open source, they have the rcovery source code publicly available making it easier to build customized versions.
A customized recovery such as the ClockWorkMod enables backing up and installing cutom ROMs super simple.
Booting into recovery mode
Booting into recovery mode is super simple and not dangerous at all in anyway to your device. the process differs depending on which device your using but it usually involves powering the phone while either holding the volume up button, the volume down button or both. (simply Google how to access recovery mode using your particular phone)
Once you do that, your phone boots into a screen that looks like this:
While the modes can look a bit different on various devices, the options are pretty much the same.
What can you do with android recovery mode?
It sucks when you forget your password/pattern and email recovery is not working for you. There is a factory reset option on the recovery mode that allows you to just wipe your entire phone. the bad thing about this is it doesn’t just delete the pasword, it cleans the entire internal memory.
Making Custom ROM backups
If you have rooted your phone, it is higly adviced that you back up your custom ROM just incase shit happens and trust me, ‘shit does happen’.
There a backup and restore option in the recovery mode. This is where you go to back up and also where you can to restore when everything goes to shit.
You can go to a computer and downloade the latest updates and copy them to your memory card. You then have to make sure that the file is placed in the root folder of your SD card else it won’t update.
After that, you just boot into recovery and select ‘apply update from external storage’. Search for the update file in your SD card and the phone will update.
NB: You use the volume keys to navigate up and down and the power button to select your options.
