Naturally, one of the things that get the most interest from Android users is the firmware update, regardless of the brand they are using. With Apple, things are quite simple, since this company is rolling out the updates simultaneously on all their devices. However, things are not quite like that with Android, where it takes a while to begin a rollout and then you may experience errors or delays. There are two ways to update: either OTA (over-the-air) or manually.
The OTA updates are the easiest to understand and follow. Whenever the phone receives the update, you will get a notification that will let you know you can install it, so you just have to press the start button. You can even check manually if you go to Settings/ About Device/ System Updates and then hit Check for Updates.
Lots of users prefer to go for manual updates for various reasons, for example if they don’t have a stable WiFi network connection, or the device is not receiving OTA updates anymore.
- Find a ROM
The first thing you should do if you want to update the Android firmware on your own is to find a ROM. You can find the official ones on the manufacturer’s websites and then check the appropriate ROM for the device you have. Alternatively, you can also find some custom ones, but that depends on your preferences.
- Install It
In order to install the ROM, you have to identify the program that best suits your smartphone brand. Alternatively, you can also go for a custom recovery, which needs the device to be unlocked and rooted. Some of the programs you can use are KIES, Odin, Flash Tool, HTC Sync Manager, HTC One Tool Kit, LG PC Suite, KDZ Firmware Updater, RSD Lite, Custom Recovery, ROM Manager etc.
