Mobile Odin: Flash Samsung Firmware From the Phone Itself

Why people liked it

The desktop version of Odin runs on Windows. The reviewer, a Mac user, valued being able to flash official firmware without booting into Windows or being tied to a computer at all.

Inject Superuser and Ever Root

These two options were the notable features. They let you flash a stock Samsung firmware that was already rooted when it first booted. The scenario described was a Galaxy Note or Galaxy S II that had been through many custom ROMs and showed the yellow triangle or system problems from bad mods. Flashing an official firmware with these options gave a clean, rooted stock system.

The yellow triangle

The yellow triangle warning appears when a phone has been flashed with unofficial software. Because the app installed an official Samsung binary, the warning disappeared afterward.

Updating without a computer

For people who always wanted the latest official releases, the app could flash newly released firmware and try to keep the existing root intact, all from the phone.

Risks

Flashing firmware can brick a phone and may affect the warranty. It needs root and care. This page does not link to the app or firmware sources.
