Bell Galaxy S2 (i9100M) Unlock Guide with Steps



To all the people who are paying people to root their phones or paying big dollars to unlock your Bell Galaxy S2 here is a guide to do it for FREE!

Edit: Please ensure you are on KG2 before proceeding. You want to use a rooted kernel that matches the ROM you are currently running. Dial *#1234# to find out

1. Go to this XDA thread: XDA Developers Galaxy S2 Root and download this file: CF-Root-SGS2_JP_XSG_KG2-v4.1-CWM4
*Remember!: You should be flashing the rooted the CF-Root Kernel that matches your current firmware. If you are on KG2 then this KG2 root kernel is the proper match. If you are on something newer, then you can root with a newer CF-root kernel which can be found in the thread listed above.

2. Next, unzip the file you downloaded. There will be a file left inside. Leave it alone.

3. Next, download Odin. Odin is a flashing tool used by Samsung developers to flash roms, kernels etc. Unzip Odin into a folder and leave it for now.

4. You will need to install Samsung Kies which is like iTunes for your Samsung Phone. If you have not you can get it from here: Kies Canada. Make sure Kies fully installs and connect your phone at least once so it loads all the necessary drivers. Then close Kies and disconnect your phone from computer.

UPDATE: If you don't want Kies you can instead install just the Samsung USB drivers from HERE

5. You will need Debugging to be active. To do this on your phone, go to SETTINGS>APPLICATIONS>DEVELOPMENT>check debugging

6. Next, go to the folder on your computer where you have Odin and launch it. Press the PDA button and select the file you unzipped in step 2 (CF-Root file)

7. Power off your phone. Now, before connecting your phone to Odin you must put it into download mode. To do this simply press: HOME button, VOLUME DOWN, and POWER-all at the same time.

8. Then connect your phone and let it load all the drivers. Once Odin shows a YELLOW com box you are good to go. Press start and boom it will install the patched kernel. Your phone will reboot and it will be rooted. This means you have full access to system files and is like jailbreaking on an iPhone.

9. Now simply open the Android market app on your phone and download the free app called "Galaxy_S Unlock" by Helroz

10. Open the app and allow it superuser authority if it asks. Then click the tab that says unlock

11. There will be 3 steps listed. Press step 1. Then step 2 (and let it completely reboot...may take a few minutes). Then once rebooted open the app and press step 3.

Your phone will now work with any SIM.
Congrats!

My Galaxy S2 took 2 minutes to root and unlock. Hope this was helpful to people.

PS. Rooting will void warranty but it is reversible. If you need return it use Odin to flash back the stock rom with one from XDA or use the one on my server below.

*The ROM on my server is Bell KG2 and is for odin. Download the rom as a ZIP. Extract it and you will be left with a TAR file. Select PDA in odin and flash as instructed below.

How to flash a custom ROM (non-Odin roms)

*Please be aware that flashing a custom rom means you will need to wipe your data which includes your account setup, text message history, contacts, and apps. It will NOT erase photos and videos.

* I highly recommend you do a nandroid backup first by going into BACKUP/RESTORE and selecting Backup (backup to internal if you don't have an SD card)

Backup your SMS messages: Use SMS backup and restore
Backup your apps: Titanium Backup (free)

*to backup accounts: Use Titanium to backup ACCOUNTS and ACCOUNTS & Sync Settings, Bluetooth Pairings, Contacts Storage (unless you are using gmail for saving your contacts. If so then don't back this up)

IN recovery, VOLUME keys are navigation and POWER button is select.

Step 1: Download the rom zip file using your computer and copy to somewhere on your phone. Say a folder named ROM on your SDcard

Step 2: Reboot into recovery (see above how to do this)

Step 3: In recovery go to WIPE/DATA FACTORY RESET

Step 4: Go back to the main menu and select WIPE CACHE PARTITION

Step 5: Go back to the main menu and select INSTALL ZIP from SDCARD
INTERNAL SD means phone memory in case you copied the zip to a
phone folder. Choose your rom.zip

Step 6: Let it flash, and then go back to main menu and choose ADVANCED
Then choose WIPE DALVIK CACHE and then FIX PERMISSIONS

Step 7: Go back to the main menu and select REBOOT SYSTEM

Please allow the phone to fully boot (it may take some time). Don't touch the phone for a few minutes after boot. Let it settle and then reboot. THEN set up your phone.

*If your flash went bad because of a mistake or corrupted file you can always boot back into recovery and restore your backup.
