[Q] Assistance needed with first root of SG2 i9100 - Galaxy S II Q&A, Help & Troubleshooting

Hi guys. I have been a frequent visitor and learned alot about android and features. I am ready to root my galaxy s2 i9100
My details are :
Android version: 4.04
Model number gt-i9100
Baseband version: i9100XXLQ6
Kernal version: I9100xxlbq-cl911584
build number: IMM76D.XXLQB
I downloaded
ODIN 1.85
CF-Root-SGS2_XX_XEO_LQB-v5.6-CWM5
I am not seeing the original kernal file up for download for my version. What else do I need for my root? Is there any advice such as best method and such. Thank you kindly everyone. Mods, if I posted in the wrong section, please move my thread to the correct location.

That's all you need mate. This kernel is declared safe by Chainfire but as any 4.0.4 kernel should not be used to wipe data because of possibility of emmc cap bug rendering your phone bricked. Root with this kernel but make sure to switch to custom safe one before attempting to wipe data.
Best of luck

Which one would you recommend for wiping data? i assume by wiping data you mean unrooting. am I right?

Essentially flashing using a 4.04 firmware will brick the phone? or is it when I flash, it will be bad to flash using a 4.04 firmware? Sooo confused.
If anyone has the steps what I should do, please tell me. I am worried about bricking.
If I root the phone, when official JB comes out, will I be able to update?

---

any help guys? The thread isn't very clear what do I do if I have this kernal. Do I downgrade before rooting?

---

Insted of flashing that Cf root kernel with Odin or Cwm, flash Siyah 4.1.5.

I actually have the same HW version in my new SGS2 and I have checked with eMMC check (downloaded from Google Play) that my chip is safe from "brick bug" :laugh:
Now the question is: which kernel to choose, CF or Siyah ? I'm planning to use CyanogenMod 10 on this phone, does kernel version matter at all in this case ?
/edit:
ROM will be either original CM10 or one of the variants (like HellyBean for example)

If GotBrickbug app by CF said your chip is safe than it shouldn't matter what kernel you use. Safe hardware.
Personally I always prefer rooting with CF kernels that match my FW version. Then if you're still unsure about the chip... flash siyah, go to advanced (while still in recovery) > reboot recovery. Then wipe data with siyah kernel just to be on the safe side. I always keep siyah 3.5.2 (the first transisiontl ics/jb kernel) for those purposes. CM10 built in kernels are all considered safe so that's the last time you'll ever be worried about it.
Best of luck, man

Thank you very much, I ran emmc check and I have a sane chip.
if I flash with the CF LBQ, what is my next step?

your phone will be rooted and u can then choose to install a custom kernel like Siyah v 4.1.5 on ur phone which gives u the latest CWM recovery thro which u can install any custom rom of ur choice(meant for i9100 though) on ur phone

Thank you very much!
If my questions seemed noobish, its because I want to be very sure. It my first expensive phone.
a question though, When samsung upgrades us to JB, will I be able to update it?

Samsung releases firmware in various regions and with varied carriers. So I bet that till it is officially released it will take time but when it does you will get OTA if your are on 'STOCK' ROM. but if you move away to custom rom then you will have to update manually.

So essentially I need to revert to 4.04 stock to upgrade? How do I do that?

To revert back assuming you didn't do backup before, download 4.0.4 firmware for your region on sammobile and flash it using odin.. Then to upgrade it when official update are up just hit OTA, kies, or flash it via odin the same way like you flash 4.0.4..
If you don't have idea how to flash then google it, theres plenty much tutorials out there.. hope it helps

Ohhhhhh. I get it. Flash using CF, or CM 10, use triangle app to remove warning triangle and if I need to unroot, flash with 4.04 (my region) using odin? Sound pretty simple. Am I missing any steps?

Actually I get confused myself hehe, by "Flash using CF, or CM 10" you mean flash what? The rest are ok..
Well, let's put this simple, Flash the CF-Root for your phone then you're rooted now, if you want to flash custom rom such as cm10 then flash it (the cm10 zip file to be flashed on recovery mode and don't forget to read the cm10 instruction before & after flashing), if you want to get rid of the triangle then do it with triangle away, finally to unroot and revert to stock, just flash stock firmware via odin..
