UPDATE: Applicable to any GT-i9100 4.1.2 firmwares

The most easiest way to root LS8 is to flash CWM-SuperSU-v0.97.zip through stock recovery

Advantage: NO YELLOW TRIANGLE

Steps:
1. Save file to external sd card
2. Shut down
3. Open stock recovery (press power + vol up + home button)
4. Install zip from external sd card
5. Select the file "CWM-SuperSU-v0.97.zip
Wait and reboot

For those who don't have external sd cards.. click this thread:

Flashing the latest siyah and philz kernel can also root this rom. To remove the yellow triangle. Use triangle away of chainfire

Goodluck on rooting guys!

To UNROOT?
reflash the XXLS8 4.1.2 official firmware

Re: Steps: Rooting xwls8 4.1.2

Just a note, for the above to work,you need an external SD, not internal from the phone.

Edit: I know you have mentioned it, but many people like me, tried to flash it from internal SD.

hi
i am pretty much newb at rooting and flashing.
i flashed the official jelly bean on my samsung s2, now i want to root it!

But i have a problem, i dont have sd card in my phone, so i have to flash using internal card.

In recovery i only have :
apply update from adb
apply update from external storage.
appy update from cache

When i chose "apply update from external storage" i get E:Failed to mount / sdccard ( No such file or directory )
I didnt tryed the two other options, as i dont have what they do/mean.

No option "install zip from external storage"

First time rooter here.

When I got to stock recovery (fresh install of official spanish JB firmware), the only options that I see are:
1. reboot system now
2. apply update from ADB
3. apply update from external storage
4. wipe data / factory reset
5. wipe cache partition
6. apply update from cache

Is option 3 the same as "install zip from external storage"?

Really easy and simple and it works :) ....but to add CMW do I have to re-root some other method or some other kernel or is there just CMW that I can flash as zip etc....?

Hi. Has anyone been succesful at flashing Siyah without wiping the device on LS8?

When I did I could not get pass the blinking Siyah logo. After two blinks, the phone would turn itself off... Any suggestions? Thanks.

Well, I could flash Siyah beta4. I guess there was some problem with the stable version...

EDIT: By the way, I flashed from internal SD card. At least in my device, when it says "external sd" in stock recovery it actually points to the internal SD.

All you need to do is flash Siyah v6 beta4 via ODIN. Not only will you have a better kernel then stock but you will also have root, custom recovery (cwm), cwm manager and SU to allow/disallow root apps.

Sorry , for routing xwls8, Could you please advise me what are the difrences between these 2 ways:

1) http://forum.xda-developers.com/showthread.php?t=1877270&page=153
[29.01.2013][PhilZ-cwm6][i9100/P] v4.00-b30 Safe Stock Kernel+CWM6+Root-XXLS8

2) http://forum.xda-developers.com/showthread.php?t=1994544
[How To] Root [I9100][ROM 4.1.2] With Stock Recovery

Pros and Cons? Which one is better?:confused:

Thanks

If i'm correct, I think 1) actually replaces stock recovery with a different recovery (CWM), and flashes a modified (rooted) version of the stock kernel. 2) keeps the stock recovery and kernel and only purely roots your phone.
The advantage with 1) is that you can use CWM which has a lot more features such as backing up instead of the rather useless stock recovery.
Not sure about any cons.

OK , many Thanks for your reply , because I prefer to be close to default kernel and latest and safe method what about little compression between these methods:

    Hello,
    I am new to this forum. I recently upgraded to the Spanish Jelly Bean FW and would like to root it. As you mentioned in earlier communication we can root from external card here i am confused if that is the phone memory are you talking about or the External SD Card. Well i do not have an external SD card can i root though?


    Yes. Click the link I provided. Though, it's kinda tricky.. if u want an easier menthod.. just flash the latest philz kernel via ODIN.

    This method is very good, but is there a way we can unroot the phone if we don't want root anymore at some point?

    Yes. Reflash the xxls8 official firmware via ODIN
