Introduction to Octoplus

OCTOPLUS is one of few SAMSUNG service tools that uses slightly different algorithm to servicing SAMSUNG devices. Because OCTOPLUS uses different algorithm, it develops and uses a native firmware file format for servicing SAMSUNG devices and this file type has an extension which is known as .OCT.

Hence, before you can flash or service SAMSUNG devices using Octoplus, you need to have gotten the Stock Firmware of your SAMSUNG device in .OCT format which is the format recognised by Octoplus.

In the section that follows, we shall discuss how to download Official Samsung firmware for all devices hence, how to convert them to Octoplus supported format.

Where to Download Official Samsung Firmware

Because Samsung does not make a repo where all their devices firmware can be downloaded known to the public, this has made getting their firmware a bit difficult though, there are some reliable sources, each from free to paid repositories where official Samsung firmware can be downloaded.

Sammobile for example, has been a relaible source where Official Samsung firmware can be downloaded for a long time.

Sammobile has free and premium features though, their FREE feature is more like a waste of your time whereas their PREMIUM feature could be considered too expensive for anyone who needs to download for a single device or who only needs Samsung firmware once in a while.

Samsung Official Firmware Download Links

In the list below here, I have contained a few list of trusted repositories where you can download official Samsung firmware, from completely free repo that offers complete premium services to those that are strictly paid services.

I have arranged them in order of thier priorities.
