How to put your LG T505 into Recovery Mode
Recovery is included on a separate partition from the main Android OS on all Android devices.
You can boot directly into recovery mode and use it to factory reset the device, delete the cache partition, or apply software updates.
It can help you fix your device.
1. For a start of this process you will have to turn off your device.
2. Wait few seconds and press and hold combined buttons: volume down + power button.
3. As soon as you will see the LG logo on your screen you can release the buttons.
4. Then after a moment of waiting you should reach Recovery mode screen. Good job!
What does it for? In the past, a phone is more of a device used to make calls or text. However, it's much more than that.
Most Android devices are now defaulted with a fairly simple Recovery mode with features like Reboot System Now, Apply Update from ADB, Apply Update from External Storage, Wipe Data/Factory Reset, Wipe Cache Partition, Apply Update from Cache.
Just like a lot of other things with Android, even the Recovery Mode can be customized to do more things.
