I do not own the, "G", variant and so therefore you have reached the limit of my knowledge on the subject.

Can I suggest re-posting that question on the i9100G thread as they will be up to speed.

The Galaxy S2 4G (GT-i9210T) is similar in hardware specs to the AT&T Galaxy S2 Skyrocket. Firmwares differ but the rooting procedure is compatible afaik.

Thanks once again to Samsung and the carriers for thoroughly confusing the issue.

thank you guys.
finallyyy FLASHED to LPG via Odin yesterday and ROOTED my S2 today(first timer ). wat a relief. had never thought of such procedures during the last 8months of having the S2. it really was a smooth process with the help of Ironass guides.
now I would like to clarify few things before getting deeper into the stuff. plz advise.

1- i have done nandroid backup(through recovery mode). is this procedure exactly the same as doing backup from within the CWM app? I understand this a 'system restore' thingy. wat is the scenario that this backup should have to be restored again? if I FLASH different ROMS and then do this nandroid restore while using someother ROM, would it delete all that and take me back to right where I am now?

2- next about the Titanium backup. I have bought the Pro version. just update all apps and data using that, rite

3- before proceding to the ROM flashing procedures, is there something that should necessarily be done? in case something goes wrong

4- ROOT EXPLORER app itself should be installed? or apps like androzip and astro would do the same work?

5- USB debugging mode should be always enabled after ROOTING is done?

6- Odin Ver 1.85 and ver 3.04. I saw these versions, but Ironass guide says v1.85. is that a better one?

7- the 'TRIANLE AWAY' app, should it be installed now, or sometime later, when in need of warranty again?
thank you all. cheers....

1. a CWM (or nandroid) backup is a complete snapshot of your current system barring the modem. whatever you do to your device in terms of roms, apps, data etc, restoring it will return you to the state your phone was at the time of taking the backup. What scenario to restore????? if you dont like your current setup/rom, if your device wont boot, if you lose your status bar, the list is endless.

2. just use it to back up your user apps+data, and possibly some selected system apps (mostly data only). Dont restore system apps/data between firmware versions as this may cause FC's

3. Before flashing a new rom, take a CWM backup then format /system and factory reset (or run my Nuke script. I see you have already read my full wipe thread so that pretty much sums it up.

4. use ES file explorer

5. No, it doesnt matter.

6. You can use either. 3.04 can also be used on the GS3

7. Install it if you want, or get a USB Jig off eBay.

Not quite sure how to deal with CWM recovery as I did not install it on my phone before i tried the root (no excuse there). As for other Kernals, I tried one other and same result. Not too sure about trying one that doesnt match the stock kernal i replaced?? I have read in other threads about reflashing a stock kernal. Any other ideas??

By virtue of the fact you followed this guide (presumably) you will have CWM recovery on your phone

Anyway... in case anyone is interested... I found the next closest kernal (LPD from LPB) reflashed with Odin and now it works fine. Hawkers advise was sparse - but on the money.

Hi, I have a small confusion. Recently I rooted my S2 for the first time after flashing the stock LPG firmware. Using the CF root file attached along with the LPG firmware in an XDA thread. After that I noticed the CWM app in the app manager. But now after flashing the RESURRECTION REMIX 2.2 ROM, this CWM app is not seen in the app drawer. But I still have root.
Wat must have happened.
Should I re flash the CF root file once again to get that CWM app in the app drawer again.
Since I am using the resurrection remix ROM now, flashing the CF root file of LPG could be done or avoided? Please advise.thank you.

It is possible to lose root when flashing ROM's.

To check that you still have root you can install Root Checker Basic, see post #2.

To obtain CWM, just re-root using a compatible CF-Root kernel as per post #1.

Hi,
Yes I used the app, root checker basic, and it says its rooted.
By compatible CF root kernel, Wat did u mean. The kernel of the custom ROM I am currently using?
Or the kernel of the LPG stock firmware which I used, for rooting the first time?

Hey everybody, I just rooted my 3 (Yes, Three) days old Samsung Galaxy S2, with the help of this guide, all the process from the moment i hit the Start key to the moment that my phone restarted and it wrote "Passed", just toke about 5 to 10 seconds, it is the most straight forward way to root SGS2, Thanks to ChainFire for his work and Ironass for this helpful guide, now i am going to part 2, factory reset, clean everything, nandroid backup, and then a new ROM,

This is by far the most comprehensive thread on rooting GS2 I've found on the net! Planning on taking the plunge tonight but I a have a doubt on how to install SiyahKernel SGS2 v3.3.2. Can I follow the instructions given at Siyah kernels 2.6.7 -> 12 A Dummies Guide to installation and settings??

Thanks in advance.

That kernel is for Gingerbread, Android 2.3.x. If you are on ICS, Android 4.0.3, you will need SiyahKernel SGS2 v3.3.2 from here. Flashing it is the same as the Gingerbread version. Just don't use the settings.

One more question Before I root is it sufficient that I clear my USB storage (internal) and factory reset my phone?? Or is there anything more that I should do?

You don't need to do that when rooting your phone! See posts #1 and #2.

Ohk Thanks! Sorry, my bad! I had to factory reset my phone today anyway because of some problem with my stock ICS firmware. Had posted on the forum regarding this problem - all apps being shown as not installed! Please help!

Thanks! Gonna root now after a small prayer Fingers crossed!

My advice, for what it's worth... Take it nice and slowly. Read everything. Double check everything. Don't panic.

We've not lost a man yet...











of course, there's always a first time!

My device is running ics 4.0.3 dxlpb firmware. Thanks in advance
Hello and welcome to Android Forums wolflet27!

Unfortunately, knowing that you are on DXLPB firmware does not help with the choice of CF-Root kernel.

Please see under, "The Root Kernel", in post #1 which describes precisely how to ascertain the root kernel needed for your phone.

ironass, walker..thank you guys for the most elaborate and structured rooting process. Gonna flash in Siyah 3.3.2 and a decent ROM tonight. Might have a few
queries to bug you guys with

Thanks again!
Congratulations ares05!

I trust that you have made Titanium Backup and nandroid backup as well as backing up your effs folder, as per post#2. These are your, "Get out of jail cards", that we modders rely on.

Which CF-Root kernel did you use to root your phone?

Have you a link to it?

Great Guide. Would like to just clarify before I take the big step. Ive got 3.0.15-i9100xwLP7-CL340913 DPI@DELL134#3 on my handset. Im thinking i need CF-Root-SGS2_XW_XEN_LP7-v5.4-CWM5.zip as it has LP7 and XW in the name. Is this correct of is there something more relevant. Ps, which virus apps actually work on Android as i hears theres a new Android botnet..

Hello and welcome to Android Forums, (The Asylum), Lenard The Pig!

Your choice of kernel is spot on.

As for an Android antivirus software, personally, I don't use one as I believe that the best way of protecting yourself is by not being stupid. By that I mean that if you follow the guidelines laid down in this post you are pretty much covered.

Even the best Android antivirus software is no guarantee I'm afraid and could lull you into a false sense of security. Besides, being rooted means that you can have nandroid and Titanium backups that you can revert to easily, see post #2.

Having said that, I know that some of my colleagues on here use an antivirus software and three spring to mind...

Avast Mobile Security free.

AVG Antivirus free. The Pro version is Ģ6.30p.

F-Secure Mobile Security Ģ8

Yup that's the right kernel you've got there. I used the same one yesterday to root my S2.

Ironass, I've got one of those noob queries I told you about earlier

The more I read, and I've been reading a whole lot, the more questions that pop into my head.

Can we use any ICS ROM with the ICS Siyah 3.3.2 kernel or are there any compatibility issues between ROMs and kernels?

Pardon the ignorance

Thanks!

This is where the confusion begins...

That kernel is the XX OXX LPB for the Eastern European firmware that was released back in April, I think.

Your DXLPB firmware, for Singapore, Malaysia, Thailand and Vietnam, which came out last week is not compatible with that CF-Root kernel I'm afraid.

I have just done a quick Google and cannot find a CF-Root kernel for DXLPB as yet.

The nearest that I can come up with is the DXLP9 CF-Root kernel which may work as it is close.

Since you have already got your stock DXLPB firmware which you have, correctly, flashed already, to get you out of trouble... you could try that kernel and see if you can get root with it.

If not, you will have to sit tight until there is a CF-Root kernel for the DXLPB or you could try this method, here.

Have you enabled USB debugging as per post #2?

EDIT Just noticed you checked USB debugging.

So, you have your phone in DOWNLOAD MODE when you connect it to Odin via USB?

You have also ensured that Kies is NOT running in the background?
