No, to root the phone you just have to flash CWM recovery and flash the Superuser update package. No need to flash that ROM if you don't want, that way is just really easy, because everything is done for you!

Ahhh...I get it..thanks for the help! really appreciate it!
[T-Mobile Samsung Galaxy S II SGH-T989] balla786:
So I followed the steps in the first post to the point where I was able to successfully flash CWM v5.0.2.6 on my Telus T989D.

I wanted to do a backup first before I did anything else.

I went into CWM --> Backup & Restore --> Backup -->

get an error msg: Can't Mount /sdcard

Is it due to the fact that I don't have an SDcard installed on my phone, and wouldn't it default to save the nandroid backup on the internal memory or is an sdcard necessary?
[T-Mobile Samsung Galaxy S II SGH-T989] balla786:
Well i tried nandroid backup after i put an sd card i had lying around and it worked. going to flash super user and try a custom Rom.
[T-Mobile Samsung Galaxy S II SGH-T989] balla786:
I followed the steps to put CWM on my phone here;

http://rootzwiki.com/showthread.php?8748-HOW-TO-Rooting-the-T-Mobile-SGH-T989-(SGS-II)via-ODIN

The last step was to flash the superuser zip from SWM.

I put the zip on my sdcard, booted up into CWM, attempted to flash the zip, got this error:

E:Error in /sdcard/su-3.0.5-efgh-signed.zip

(Status 0)

Installation aborted.

This is a pic of the error that another user reported:

http://rootzwiki.com/index.php?app=...=attach&attach_rel_module=post&attach_id=9600

I rebooted, my phone, I do find that I have a SuperUser icon now.

Is there a way to test if my phone is rooted now? Should I try a custom rom, like Beastmod?
[T-Mobile Samsung Galaxy S II SGH-T989] rdfry:
I flashed the super user zip file and received the exact same error. It installed the super user apk, but would not allow root access. Flashed it again same results, deleted it from the phone re-downloaded it and copied it back to phone. This time it installed correctly.
[T-Mobile Samsung Galaxy S II SGH-T989] balla786:
Did you remove superuser from the phone and reflashed it from cwm?
[T-Mobile Samsung Galaxy S II SGH-T989] krash69:
Everything went as stated, odin said pass saw my phone rebooted and still no recovery ? i am on telus, have rooted nexus and desire before, any help ? thanks for your time and sorry if im missing something obvious
[T-Mobile Samsung Galaxy S II SGH-T989] balla786:
When you were in odin, you selected PDA, found the CWM .tar file and then flashed it to the phone?

Do you have the Telus S2 X? You would need turn off the phone, press and hold both the Vol+ & Vol- button, then press the power button, once you feel the vibrate of it turning on, let go of the power and just wait a few seconds, you should get the blue CWM screen.
[T-Mobile Samsung Galaxy S II SGH-T989] krash69:
I was in Odin, selected pda, browsed to cwm.tar file called recovery.tar or something and then recovery-cmw-hercules.tar and also tried GT-I9100_ClockworkMod-Recovery_4.0.0.2.tar and recovery.tar.md5 after i bricked it lol. I am on telus i have tried your method of three buttons and let off after first vibrate and it just boots, also tried volume down and power but it just goes to original menu as pictured in beginning of this thread, nada. must be something simple im missing or have the wrong file, thanks for your input

You don't say what phone you have either.. T-Mobile or Telus

Both of these phones have different methods

[T-Mobile Samsung Galaxy S II SGH-T989] krash69:
I did say Telus, finally got it to work although im not sure how, took the battery out after the odin write and was having problems booting into cwm as the method of holding power and both volumes just booted normaly after I tried volume down and power it went to reboot normaly and i held down power and volume down again and it vibrated 3 times and then I was in. now i just use the app to boot into recovery, cant wait for miui or something to actually put on it or perhaps a voodoo kernel. thanks to everyone for their help Krash

<SOLVED>Nothing happens for me when I choose the recovery file as PDA and press START in Odin I see nothing up at the top, assuming it should see my phone. Suspecting it may be because I'm running 64-bit Windows 7? I don't see the device recognised when I plug it in.

When I unplug the phone (in download mode) and re-insert, I get an error from Windows "Gadget Serial Device Unplugged" after it instals the driver.

Odin says (Unplugging and re-plugging and leaving it in):

How to root your Galaxy S2X ( Telus )

I have rooted my galaxy S2X (telus) with superoneclick v2.2-shortfuse using the zergRush exploit.. it worked on the first try :D

only make sure you have the usb debugging enabled and correct drivers installed...

the whole process takes about 5 to 10 minutes, please wait until the program confirms the success before closing it, even when it doesn't look to be working, it is still hacking the phone..

Two weeks passed since i have rooted my phone and everything works perfectly ;)

Hi, I'm fairly new to android (about a month or so) but not new to modding. I decided to root my sgs2 x last week and I'm on Juggernaut 3.1 with jugs 0.3 kernal right now. The new 3.69 update to Juggernaut came out today.. and I was wondering: if I want to update my rom to that, will I have to wipe everything and install as a new rom? So basically, will I have to install my apps again, do all my settings again, set it up like I did the first time?

Or is there a way to backup all the apps, settings, themes, contacts, SMS, etc so that when you update the rom you can put them back to the way they were?

Thanks! :)
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
You only need to wipe if you are getting any weird issues or bugs. You can use Titanium Backup to backup all applications, contacts are synced with Google, SMS you can use this (https://market.android.com/details?...mNvbS5yaXRlc2hzYWh1LlNNU0JhY2t1cFJlc3RvcmUiXQ..)

Themes and settings you need to do yourself though.
[T-Mobile Samsung Galaxy S II SGH-T989] SGS2X:
Thanks :) also I wanted to clarify something.. are you supposed to wipe dalvik cache before or after flashing the rom/kernal?
[T-Mobile Samsung Galaxy S II SGH-T989] skadude66:
Usually you can do it after and still be okay, but I've gotten into the habit of wiping before and after flashing the ROM, just in case.

So thanks to the guides on here I was able to root my phone today for the first time and flash a custom ROM today (juggernaut) with no problems. I've got one question that I can't seem to find an answer to though, If I want to install i different rom, what steps do I have to take? Do I have to go back to stock first, or can I just go right back into the boot menu by holding down the Vol up & down and then pushing the power button? I looked for an answer to this on the boards, but couldn't come up with anything when using the search function
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
that's actually the best practice when you switch between similar ROMs, as they get more and more polluted if you don't go back to stock first

if you are just upgrading to a newer version of the same ROM then there is no need, however you might still require to do a Wipe in some major upgrades.
[T-Mobile Samsung Galaxy S II SGH-T989] Hail2theskins:
is this the same as doing a factory reset from CWM? I'm trying to go from Juggernaut to Beastmod just to check them both out here. Unfortunately once I went to Juggernaut I started getting horrible 4g speeds. It may be my location, so I'm going to wait, but it's good to know these things anyway.

Thank you for the guide. I would strongly recommending changing steps 1-5 because they make no sense at all. I spent 30 minutes trying to figure out how to do it. I would change them to:

1. Turn phone off

2. while phone is off, hold down the vol + and vol -

3. while holding vol + and vol -, connect phone to Computer via usb

4. When the Warning sign shows up, release the vol + and vol -

yes, just run the superoneclick

the rest are optional

after that you can flash any ROM you want

[T-Mobile Samsung Galaxy S II SGH-T989] joking:
The instruction is correct, just follow it to the T. Basically, you didn't flash any ROM but CWM recovery image and install su.

I flashed su in CWM instead of Superoneclick method.

[T-Mobile Samsung Galaxy S II SGH-T989] lavero.burgos:
For the ones wondering about updating ROMS or flashing NEW ROMS and/or when to root, let me make it clear.

Cases:

1. When to root?

Well its simple if you don't want to use a custom ROM then use superoneclick, but if what you want is to flash a custom ROM then first verify that the ROM comes with su, superuser, busybox that means the ROM is already rooted, if it doesn't then after flash the ROM, get in recovery flash superuser.zip wipe cache - dalvik cache & fix permissions, reboot.

2. Update the same ROM to a new version

you just have to clean cache and dalvik cache(cwm>advanced) before and after to be safe, just in case you notice something unormal then proceed to make a factory reset/wipe data is the same, by doing that all your apps, cache, sd-ext and settings will be removed so make sure you do a backup with Titanium Backup first.

3. Changing to a different ROM

Is necessary to make a FULL wipe: data/cache/dalvik cache before and after flash the ROM to be safe. Also sometimes happens that system or boot gets corrupted so if you really want to make a FRESH install then go mount and storage and format system too.

Recommendation: VERIFY the md5sum of the downloaded ROM, it could be a bad download <<if you getting nuts with a Rom NOT behaving the way it should even after try a factory reset>>

PS: correct me if im wrong with the root part :D

PS2: If i missed something let me know :p
