Upgrade Firmware

Samsung started making its flagship s device with the launch of galaxy s i9000 way back in 2010.Since then we have seen 6 of its generation.Though the hardware of this device doesn't even match up with the low end offerings from samsung right now it still received lot of unofficial custom firmware which made it to stand out in the development community for a long time.

Till now we have seen some good number of custom roms for this device which used android lollipop as a base.Everyone might have thought that lollipop could be the final firmware that it might receive as the hard itself being underpowered for later updates.But as you know legends never die and if you still own galaxy s i9000 aka galaxysmtd then there is a good news for you.You can now update it to latest version of android which is 6.0 aka marshmallow.

Though the rom is somewhat buggy you can still use it as a daily driver for sometime though but not forever.If you are here to update galaxy s i9000 to android marshmallow then proceed further but if you know how to update it then don't worry we are here to help you out.

But as you know this rom is still early stages of development and might become stable for couple of releases.If you don't mind using this omni custom rom with some bugs as a daily driver look ahead.As flashing is a risky process,we hold no responsibility at all if this has bricked you device,so proceed at your own risk.
