No, a bricked phone is not a phone made out of a brick. It means the phone has the function of a brick. And it can give you quite a headache.
A bricked device means the device’s OS is damaged severely enough that it is not usable. There are two types of a bricked device: a soft brick and a hard brick.
A soft bricked device usually gives some signs of life. It usually does power on and the screen is lit. However, it usually get’s stuck on on the bool logo and keeps booting indefinitely, otherwise known as a boot loop. Sometimes, the deice boots, but crashes, and so on… These types of brick are usually easy to fix especially if you can enter recovery mod, or CWM on Android
A hard bricked device gives no signs of life. The screen doesn’t turn on, the device doesn’t vibrate… A hard bricked device is a real pain to fix, and it can sometimes be expensive.
There are many, many reasons why a phone or tablet can get bricked. If you root your Android device, you are prone to bricking you device, if you are not careful. If you are installing an add-on on your device, and something goes wrong during the installation, you can end up with a brick in your hand. Same can happen if you are installing a new OS.
However, just because your device is not rooted, doesn’t mean you are saved from a brick. And just because you use iOS or Windows Phone 8.1 on your device, doesn’t mean you are safe. See, if you are doing an update of your device, either OTA or via your PC, you can still brick your phone. How? Well, if the installation or update is for whatever reason is interrupted, you will probably end up with a brick in your hands with an apple on the back. And or rare occasions, it can “just happen”, meaning there is a small bug in the installation.
It is quite easy to prevent a bricked device. Here are some quick tips:
1. If you have a rooted Android device, don’t modify files that you don’t recognized. That usually ends bad.
2. If you are installing a mod on your device, make sure it’s compatible, or you will end up with a brick.
3. Don’t interrupt an update. Doing so will most likely brick the phone.
If you do end up with a bricked device for whatever reason, you can and try to fix it. If you can boot into CWM or Recovery mode, try flashing the stock ROM. That should fix it. Sometimes just deleting the cache and Dalvik cache memory does the trick.
But what if you have an iDevice, or a Windows Phone device? Well, you might want to take it to the store, and ask them to sort it out for you. Rooting an Android device usually voids warranty.
