Samsung Galaxy R is a variant of the popular Samsung Galaxy S2 (SII) that was announced by Samsung back in August 2011. However, it can be considered more of a cut-down version of the SGS2 as there are some important differences (compromises) in the hardware specs. For example, the screen on the Samsung Galaxy R is not Super AMOLED but instead Super CLEAR although screen size and resolution is the same as Samsung Galaxy S2 (SII). But most importantly SoC is based on slightly less powerful and now aging Tegra 2. Device ships with a 1GB of RAM and less powerful 5-megapixel camera - another cut down feature as compared the Galaxy SII. Due to these notable differences users cannot use the same rooting kernels as we advised to use in the past to root Samsung Galaxy S2. However, an XDA forum developer ardatdat has already done the hard work for us and released a pre-rooted kernel that can be used to root Samsung Galaxy R.
All that needs to be done is to download this kernel and flash the tar file through the Odin. Kernel is mainly meant to root the device, although this kernel has built-in support for the overclocking and is compatible with the popular SetCPU tool, with which users can overclock or down-clock their device as desired. Since kernel is rooted hence SU and Superuser.apk are already embedded. According to the developer kernel is quite stable based on the stress tests Quadrant benchmark, CF-Bench etc.
Note: Rooting, Jailbreaking or customizing your device can be risky, and you may end-up bricking your device! Follow the instructions posted here at your own responsibility as Inspired Geek will not be responsible for any damage to your device.
Here are some of the features reported by the developer:
- For Samsung Galaxy R (i9103) only
- Based on Samsung open source, kernel version 220.127.116.11
- Added new frequencies: 1200 & 1300Mhz
- Setting of max 1300Mhz through SetCPU
- All stock frequencies are untouched: 216-1000Mhz
- Expose the voltage settings to be set through SetCPU
- Limit the boot up frequencies to be 216-1000 to avoid unstable boot up
- Simple IO Scheduler
- 18.104.22.168 patches
- Speed up framebuffer copy
- memory copy macros and functions fine tune
- Misc. kernel fixes
- Rooted (embedded su & Superuser.apk)
It should be mentioned that this kernel should be compatible with at least Android 2.3.4, 2.3.5 and 2.3.6 versions installed on your Samsung Galaxy R. Another point to note for the novice users that since this is a kernel (NOT firmware) so no need to worry about erasure of data & settings etc. As you can see it is not very difficult to use this to root the Samsung Galaxy R using Odin. For the novice users I would recommend that you follow this guide that we have originally written to root the Samsung Galaxy S2 (SII) but procedure is exactly the same except that of course you need to flash the kernel for which the download link is provided below.
