I have not rooted and flash any new ROM on my phone.
However I have read through Chainfire's CF-Root pages and of course page 1.
I am tempted now to root the phone after considering all the +ve benefits of rooting my phone.
But before I root, I have a few questions that I hope you guys can help answer.

1. After using Chainfire's method to root the phone, will my existing apps, configuration, contact, sms be removed/wiped-out? Was not able to find any answers to this.

2. Since ODIN is an exe that runs on Windows, is there a possibility of it carrying any virus/malware? How about the tar file?

3. Should I choose this "CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4.tar" file from PDA in ODIN to root my phone since my stock kernal is KF1?

4. Is it better/easier to use Chainfire's method (zImage) to remove the triangle or just buy a jig to do this? The triangle will only show during boot up right?

Appreciate your answers!

1. I just found out from reading Chainfire's most recent and very long pages (100+ pages) that it does not wipe-out data on the phone.
2. Since I have never heard of any complaints about ODIN potentially carrying malware/virus, I can take a calculated risk to say it doesn't. Not 100% sure tho.
As for the tar file, it seems like Chainfire just added a few extra to the stock Kernal like CWM, etc before re-packaging/compressed it into a tar file.
3. Noted
4. The zImage is from the same tar file (CF-Root-SGS2_XW_OJV_KF1-v4.0-CWM4.tar)?
5. Any negative side effects so far after Rooting?

Again, many thanks!

Thank you!

I am not thinking about flashing any custom ROM. For me, the stock ROM is good enough. I just need Root access for my phone.

You can try this. It works for me.

1. You can download Mobo Player and Astro Files apps.
2. Start Astro Files app, under More->Preferences->Edit File Extensions. Add a new extension for rmvb (video/rmvb)
3. Start Mobo Player and rescan for video files.
4. Select the rmvb file and it should play with no issues.

Has anyone encountered this problem.

I suddenly cannot receive in-coming calls. All my in-coming calls immediately get diverted to my voice mail. I can however make calls with no issues.

I checked my settings, under Call Forwarding->Voice Call->Always forward is set to Disabled. But Foward when busy goes to an unknown number that I can't change.

Called Maxis but they say this is a settings issue.

Any help is highly appreciated.

Any idea if this is caused by some settings from the phone?

Data works fine as I can do whatsapp for in-coming and out-going.

I also uninstalled some apps that I installed recently.
