How to Unlock (and Root) the Bell Galaxy S2. Step by Step Guide

Sure. But KG6 is not an official release. KG 5 and 7 are official Kies.
No Bell update yet. There is a thread on xda that tracks carrier releases

hey I'm wondering which version I should update to from my stock UGKG2

[ROM + Guide]Official i9100 Firmwares KF1/2/3/4/, KG1/2/3/5/6/7 Download - xda-developers

there's plenty of options but I'm unsure which I should be using XXKG5 stock kernel or UHKG7 stock kernel OR one of the Frankenstein updates?

I understand everything I need to do just don't know which firmware to grab since I don't want to stay on KG2 and 2.3.3

(yes I understand I'll need to root again with the appropriate version after updating firmware, before someone mentions it)

I would wait. I have been reading a lot of complaints about KG5 and 7 and how KG2 seems to be more stable (on XDA). I have no problems with KG2 so I'm not going to mess with it.
 
I just got my SGS2 yesterday from Bell. I followed all the steps above and everything seemed to work. Im with Bell, so I have not tried a different sim card yet. I had to do a factory reset for my phone. It seems the root is still working. My question is do I have to redo steps 8-10 above again? Or is the unlock permanent once its done. In other word, is the unlock with galaxy s unlock a software or a hardware unlock? Thank you for posting this great guide.
 
Super !

Thanks a lot for this. Just unlocked my Bell i9100m and it works perfectly on Fido !

Only thing is, USB debugging should be turned on after step 4 because Kies requires debugging to be off.

So I would also add step 11, turn Debugging OFF.


I spent the night reading on XDA, and toher forums, but I just did what you say and it is working.

I'm on stock ROM still (bell shitty apps), and maybe will try to remove that yellow triangle...

I've been wondering..
When I first rooted my phone a few weeks ago i used this one from XDA:

zip.gif
CF-Root-SGS2_XX_OXA_KG2-v4.1-CWM4.zip
(Different than the one above, is this bad?)

and the following below:

XXKG2

Firmware info
PDA:XXKG2
PHONE: XXKG2

Date: 12/07/2011

XXKG2 Stock Kernel: Multiupload.com - upload your files to multiple file hosting sites!

Does using this have any negative effect on my phone since its not a firmware/kernel provided by Bell? Or is it only the modem that can mess things up? Occasionally my data connection seems to stop working and I need to switch in and out of airplane mode (or restart phone) to get it working again, is this because I rooted using the above firmware/kernel?

Heres my phone info:
Baseband: 19100MUGKG2
Kernel version is: 2.6.35.7-19100XXKG2
Build number: GINGERBREAD.UGKG2

Thanks!
 
Blue,

I am interested in rooting and unlocking my phone, but, for some reason am hesitant. I am, as my username suggests, a complete newb when it comes to smartphones.

Basically I want to be able to update firmware when it is released instead of having to wait for it be released in my region or by my carrier (example, 2.3.4 is not out yet for Bell). I am also interested in being able to buy prepaid SIM cards when I travel to the States (couple times a year) rather than racking up roaming and other fees to use it outside my network.

Based on that, do you think rooting/unlocking makes sense for me? What are the odds that a complete idiot screws up his phone with this process beyond repair?

Thw root kernel you chose is fine. However the rom contains a different baseband modem than bell rom. You are the fourth person complaining about connection issues with a non bell rom. That is the reason I am hesitant to flash a non bell rom. You could flash the bell modem back. The link is on xda a few posts above

Lol. It is not that hard. :) Where in Canada are you located. I could help guide you through it on Skype.

I would. That way you have total control of your phone.

I'm in Hamilton.

Thanks for the offer of walking me through it on Skype. I am having problems with my camera which is what originally led me to this site, and, then led me to research rooting/unlocking. I am within the 30 day window to exchange for a new phone, so, I think I will try that before I root.

Thanks for all the info about this subject, it's good to learn new things. :D

Thank you so much! Looks like its time to flash to Bell modem! My connection speeds suck compared to others (3-4mbps download :confused:)
 
new here.... did as OP instructed and it worked as described. however, i noticed that the battery is draining faster than before the flash. other than powersaving mode, what else can i do to improve battery life?

//edit* i'm also new to this smartphone thing... so i'm kinda paranoid about how long it would last me on a working day... oh, i also noticed that ram usage has increased by about 8% after the flash.... any hits as to why? (i made sure i ran the exact same processes as before the flash)

+ does the app juice defender really work?

Rooting should have no effect on battery life. However, there are certain processes that are massive battery pigs.

Install Titanium backup. In the app there is a tab at the top that lists applications. Select it and then freeze the following apps by clicking on them and then choosing freeze.

Wi-Fi sharing
Wi-Fi sharing manager( don't freeze any other Wi-Fi processes)
Bell GPS navigator
IMEI tracker
Social hub( 2 processes)

Freezing is safer than uninstalling.

My battery lasts 14 hours with solid use.
 
what does solid use include?

i'm the kind of person who'd browse the web while listening to music *on headphones* & running an im app.... & i know that about 1% drain every 10mins while on direct charge ^ ^;;;;;;
