Almost 10 years old, Samsung's Galaxy SII is still alive and well with the LineageOS 18.1 port and that carries Android 11. A feat for a mobile phone that in its day was a before and after for this operating system for mobile devices.
In these current moments where technology has advanced by far to even be able to fold screens or roll panels like the LG RollableFor those who have the Galaxy SII in a drawer, perhaps it is time to go through this ROM to bring it to life.
El port comes from various developers at XDA Developers for the GT-I9100 model. And among the elements that work, we can find the screen, Wi-Fi, camera, and audio, so for some things it can serve perfectly.
Yes it is true that calls cannot be made, although they can be received. For now, we can forget about GPS, FM radio, screencasting and a variety of other features that do not work. So if you consider installing this ROM, have a backup of the current firmware you have on the Galaxy SII ready.
For the installation we would use Odin thanks to being a ROM linked to the Isolated Recovery protocol or IsoRec. As details to take into account when “flashing” the ROM, mention that you have to be attentive to the data backup part, since you will have to re-partition and wipe or erase the internal storage of the Galaxy SII.
More than curious the being able to tinker with Android 11 on a Galaxy SII and it will be possible that in the coming weeks or months the ROM will be updated to activate some of the elements that are not available.
