Samsung Galaxy S2 GT-i9100G: Review, Firmware, Software Update, Rooting

Mozilla Mobile Test Drivers program lent me a Samsung Galaxy SII mobile phone to test the nightly builds of Firefox Mobile. This Android 2.3.6 (Gingerbread) phone runs off a powerful dual core A9 1.2 GHz processor with a good responsive capacitive touch screen. The device is impressive and attracts a lot of attention everywhere.


Samsung Galaxy S2 Android 4.0 (ICS) Update


On March 10, 2012 Samsung will release an firmware update for Android 4.0 code named Ice Cream Sandwich. You will find the upgrade information here on Samsung website.


Android 4.0 promises to offer better accessibility and internationalisation support. You can navigate the android phone built-in screen reader using touch gestures. There is much better rendering support for Asian languages and additional Unicode fonts are bundled with the release.


Cyanogenmod Firmware for Samsung Galaxy S2 (GT-I9100G)


The Cyanogenmod has been boon for mobile phone technophiles. The project provides customised firmware for wide variety of phones. Unfortunately Samsung Galaxy S2 (GT-i9100G) is not well support by Cyanogenmod project. Why? Samsung had changed the hardware specification of this model and none of Cyanogenmod developers have this phone model to work on.


Last week, Yang and I spent an afternoon looking for compatible firmwares to root Samsung Galaxy S2 (GT-i9100G) . After few failed attempts we found that MyGKernelV1.1.1_CWM5.tar version managed to give us root access to the phone.


Installing Boot2Gecko on Samsung Galaxy S2 (GT-I9100G)


You have heard of Mozilla Boot2Gecko. The Mozilla entry into smart phone market was unveiled at Mobile World Congress last week. Build with HTML5, CSS and Javascript, it allows web developers an open phone stack for their applications.


The Mobile World Congress Boot2Gecko videos shows a Samsung Galaxy S2 running Boot2Gecko. You should take note that this Samsung Galaxy S II model is GT-I9100. The Boot2Gecko developers use Samsung Galaxy S2 as their development platform.



Since Cyanogenmod scripts are used for Boot2gecko installation. You won't be able to install it on Samsung Galaxy S2 (GT-I9100G) without lot of hacking. Recently there has been a lot of talk about people dying to install Book2Gecko on Samsung Galaxy S2. Caveat Emptor.

    1. You might face this problem if you keep your Wifi, GPS turned on all the time. In my experience, playing streaming video would tend make these devices very hot.

      Regarding battery life,consider buying a battery pack to extend your battery life. See Samsung Galaxy S2 Power Pack
