How To Check and Download Galaxy Note 2 Official Firmware

Android is built base on the open source OS – Linux. Rooting and manually flashing any ROM via odin will void your service provider warranty, but , as developer, i  have always flash and test custom ROM on my Android devices especially Samsung Galaxy S3 and Galaxy Note 2. To flash custom on Samsung Galaxy S3 and Galaxy Note 2 is a very simple as you only need to know the basic steps on How to Root , How to  Backup , and How to Wipe. But after change to new custom ROM,  sometime you may found that the custom ROM features may not fulfill as what you have expected and want revert back  to the official firmware. So how?

If your rooted galaxy Note 2 has a proper backup, then you can revert back to the previous installed firmware on the CWM Recovery Mode . Otherwise, you need to manually download the Galaxy Note 2 firmware and flash into your Galaxy Note 2 via Odin.  Flash new official firmware via Odin not is a big issues, but you need to make sure that downloaded firmware is really meet your region and your galaxy Note 2 model firmware. You can flash and use other region or different firmware baseband, but don’t flash firmware to unsupported Galaxy Note 2 Model.
