I just obtained the Galaxy S2 LTE from Rogers, which is a an upgrade from the one I obtained from Bell.
As a result I found myself looking for an easy way to root the device, which led to multiple posts but no clear solution as to how to achieve this on my newly obtained device.
This post is merely a recollection of the posts and threads that have helped me achieve root on the SGH-I727R sold by Rogers in Canada.
Warning: I take no responsibility if you brick your phone. Do at your own risk.
Phone specs:
Samsung Galaxy S2 LTE by Rogers
Model: SGH-I727R
Baseband: I727RUXKJ7
Android version: 2.3.5
Kernel version: 2.6.35.11
Build number: GINGERBREAD.RUXKJ7

The process
My research took me to the posts above which focus on the use of the root exploit ZergRush.
1 - Download all the necessary files
2 - Run ZergRush as follows:
This requires the Android sdk with and the use of adb, which can be found in platform-tools on the sdk directory.
This is the output to be expected (this may be different for your device. Let the binary do it's job):
This will temporarily root your device (until the next reboot).
3 - Push Superuser.apk and su binary
Type the following commands in your command line shell:
This is the expected result:
Once the device has rebooted, you will have the application Superuser with root privileges which will allow other apps to benefit from it.
it is far from a one click app, and doesn't include any goodies that may be found in CMW4, but it's better than no root at all.

My research took me to the posts above which focus on the use of the root exploit ZergRush.
1 - Download all the necessary files
- ZergRush binary
- Superuser.apk
- su binary
2 - Run ZergRush as follows:
This requires the Android sdk with and the use of adb, which can be found in platform-tools on the sdk directory.
- open a command line (cmd.exe) and type the following commands
- type in "adb push C:\[location of zergRush]\zergRush /data/local"
- type in "adb shell"
- type in chmod 755 /data/local/zergRush
- type in "/data/local/zergRush"
This is the output to be expected (this may be different for your device. Let the binary do it's job):
Code:
$ /data/local/zergRush

3 - Push Superuser.apk and su binary
Type the following commands in your command line shell:
- adb remount
- adb push c:\[path_to_Superuser.apk]\Superuser.apk /system/app
- adb push c:\[path_to_su_binary]\su /system/bin
- adb shell
- chmod 644 /system/app/Superuser.apk
- chmod 4755 /system/bin/su
- reboot
This is the expected result:
Code:
C:\[path_to_SDK]\platform-tools>adb remount
remount succeeded
C:\[path_to_SDK]\platform-tools>adb push c:\[path_to_Superuser.apk]\Superuser.apk /system/app
