Root and install Kitkat on Samsung Galaxy s2 i9100 – without a computer

Root sgs2 and Install Kitkat Rom without even touching the computer.

 

If you own a Samsung Galaxy S2 GT-I9100 and haven’t already rooted it. First of all, wow, you really are patient. But by now, you have probably guessed that Samsung has deserted you and won’t bring any more updates to your phone. I like my phone a lot and the hardware still competes with new phones so there’s no reason to buy a new phone yet! Bring out the enviromentalist in you and keep your electronics a little longer!

1. Root
2. Download all files to your phone
3. Install Recovery
4. Factory erase phone
5. Install your flavor of Kitkat Rom.
1. Root – Framaroot
You’re going to need the “one click root” app framaroot. Scroll down and download the latest version or better yet, install framaroot from Google Play store. Just make sure your device is on the list of compatible devices.

It’s now ridiculously easy thanks to framaroot. Open framaroot on your phone and choose that you want to root your phone and  Install SuperSU as the action after root. There are at the time of writing, three modes available. Try them until you find one that works. For me Aragorn worked every time. If it doesn’t work, you won’t be able to continue with the next steps. Try my old manual on how to root sgs2. It should still be relatively accurate.

Alright, let’s say you’re Rooted, reboot your phone and go on to the next step.

2. Download all files to your phone

Install Rom Manager from Google play
Rom manager

Download CWM Recovery (Kitkat Compatible)
CWM-Recovery-Kitkat-Compatible-i9100

Download your flavor of Kitkat Rom and Gapps.
I have tried a multitude of different roms out there and as of now my favorite is Resurrection Remix. 3 main reasons. It’s stable, Gps works well MMS works well.
If you want this rom, head over here Resurrection Remix – XDA. Scroll down to the download section and download the latest versions available. Make sure you have both the Rom and Gapps (I use the light version of gapps. You can install the other apps from Play if there’s something your missing anyway)

3. Install Recovery
First you need to install just a normal recovery. I usually do it through Rom Manager.
open rom manager which you have already installed. And click Flash ClockworkMod Recovery. If it doesn’t choose phone version for you, choose galaxys2. I never choose i9100. I’m not sure why there are two versions but galaxys2 always works for me.

When you are done, turn your phone of. Start it up by simultaneously holding the vol-up, menu and power button. You should see a cute android spinning with things in his stomach and then you should find yourself in recovery mode.

Navigate with vol-up and vol-down and select with the power button. Choose Install zip.
> Choose zip from /storage/sdcard0 (or whatever option you have where you can find  your downloads)
Select your CWM-Kitkat-Compatible-i9100.zip and choose Yes. After you’re done. Turn your phone of and start it into recovery mode again like you did earlier.

4. Factory reset
Select wipe data/factory reset. Make sure you have all your files you don’t want to loose, backed up. This WILL erase most files on your phone if not all.

5. Install Kitkat Rom
Now you’re ready to install your rom. Select Install zip and choose your “rom.zip” file first. and chose Yes. After you have done this, install the Gapps file you downloaded as well.

Now reboot your phone and you should be done!

IMPORTANT – Only if you get a signature verification issue
If you get issues with signature verification regarding CWM recovery. Please make sure you check the MD5 Sum of the file so that it hasn’t been corrupted during download. Here’s how to do it.

Download MD5 Sum Checker >here<
And compare to this MD5.
MD5:
e755faea3d638105b29f39ebaa5abaed

If you want to check the MD5 sum on your computer it fairly simple. For windows there are applications that will do it for you. In Linux or on a Mac you just open a terminal, go to where you have your file and type

md5 CWM-KitKatCompatible-i9100.zip

press enter and the md5 sum will be displayed.
