Samsung Galaxy SII is one of the finest phone ever made by Samsung. It is this phone that won Samsung applause and cheers from the android community. Initially, it was launched with gingerbread edition of android OS. Lately, Android 4.0 Ice Cream Sandwich was officially released for galaxy s2 worldwide gradually, but ICS on Galaxy S2 was not perfect. It was laggy and buggy. I hated Samsung for this but didn’t want to downgrade to gingerbread either because being a techie, I always want to get taste of the new and the latest flavor. Like all galaxy SII owners, I’ve been waiting for Jelly Bean firmware update for Galaxy S2 officially from Samsung. Now, it is here. It is not yet live. If you connect your galaxy s2 phone on your computer, you won’t find any firmware update, but thanks to Sam mobile, they’ve leaked official Jelly Bean firmware for Samsung Galaxy SII. I’ve already flashed my phone with it, and boy do I need to say, Jelly Bean makes my s2 alive and rocking again. I feel as if my 1 year old handset is new and modern still. Android 4.1.2 i.e. Jelly bean firmware for Samsung Galaxy S2 addresses all problems and bugs which we used to face on ICS firmware. A lot of things have improved and the UI seems flawless, butter smooth and appealing. Excited? Lets head over to flashing guide below so that you could also get your hands on Jelly Bean goodness on your Galaxy S2 smartphone.
- Fully charged Samsung Galaxy S2 phone (GT-I9100) – Be serious. Do not flash unless your phone has 70% + battery capacity.
- Backup contacts, messages, everything else. – This time, backing up is necessary unless you want to end up being a fool like me. I’ve never cared to take backups before flashing my phone and I never ran into problems after flashing because all my apps, settings, data remained safe, but not this time. Unlike other firmwares, flashing Jelly Bean firmware will cause factory reset. This firmware flashing will not wipe your stored multimedia files like captured pics, videos, etc, but will wipe your apps, settings, messages, contacts and other related data.
- USB Data Cable
