Hi,
I've had a look around and can't find a thread that answers my question completely. I just want to gain root access to phone, I have no intention of flashing a custom firmware. My phone is a Galaxy S2 I9100 running Vodafone Australia's stock 4.0.3 ICS.
As I am new to rooting, I have browsed through this page but still have questions:
http://forum.xda-developers.com/showthread.php?t=1103399
I want to be able to easily restore my phone to its stock, unrooted state for warranty purposes. I'm not quite sure how to do this, Is there a way to backup my phones kernel as it is now, and be able to flash back to the stock kernel if something were to go wrong?
Also, My kernel version is 3.0.15-I9100TDULP9-CL422302 ..... The key letters being LP9? So then which one of these 2 would I flash?
CF-Root-SGS2_XW_KPN_LP9-v5.4-CWM5.zip OR
CF-Root-SGS2_DX_SIN_LP9-v5.4-CWM5.zip
Or would either work?
(Yes still going, sorry!) I also saw something called a Binary Flash Counter which counts the amount of times a phone has been modified? Would I be affected by this by just gaining root access? And if so how do I prevent that? (My ultimate aim is to root, but still keep warranty)
Thanks in advance for any help, its really appreciated.

To get back to stock look for your firmware in Intratech's thread. It also provides links for kernel only downloads.

From the thread you were referencing:
The XX and OXA identifiers are not that important. Usually a "KG1" kernel is a "KG1" kernel, and that is that. Sometimes (pretty rare) it happens there will be multiple different kernels with the same name in different firmwares, that are actually different. If this happens, they are usually only very minor changes and you should expect them to still be fully compatible. I include the "XX" and "OXA" identifiers so the very advanced users can deduce from which full firmware I have taken the kernel file.

Yes you will be affected (if rooting with CF-root method) and no, you can't prevent it. However you can reset things. The easiest way to do this is to use TriangleAway from the Play store.
Best thing to do if you want a backup that's as close to stock as possible is to root your phone & then do a Nandroid backup in CWM before doing anything else to the phone (flashing custom roms, other kernels, etc). That will give you a backup that is essentially stock other than the rooted kernel.
If you want to guarantee warranty service, don't mess with your phone (yes, I'm serious). Once you start messing with it, you should lose any expectation of warranty service should the worst happen (rooting your phone/running non stock firmware voids your warranty). Having said that, many people who have rooted their phones and/or run non-stock firmware have been able to get warranty service by going back to stock & resetting the flash counter either with a jig or Triangle Away before sending it in for service. However, this is never a guaranteed, rolled gold 100% certainty.
FXRB is right, before you root your phone, either download your current firmware from Intratech's thread, or use the PC version of Checkfus to download it. This will save you problems if you need to go back to stock in say, 12 mths, and you forget which firmware was originally on the phone.

1. Reset binary counter using Triangle away app.
2. Download Stock firmware for your country/region here: http://www.sammobile.com/firmware/
3. Flash the firmware via Odin.
Done

In addition to what Jokesy said, you say you have a Sprint Samsung s2 ics 4.0.4 fh13. The Sprint variant is the Epic 4G Touch, and has a different forum located at http://forum.xda-developers.com/forumdisplay.php?f=1281.
This forum is for the I9100, which is a GSM phone, and doesn't even work on Sprint's CDMA network.
For your own sake and future sanity, please go to and stay in that forum, and avoid flashing anything from this forum for the I9100.
I rooted my phone pushing CWM.zip and SU-busybox in recovery mode.
First CWM.zip And then su-busybox in the Clockwork orange mod. Its rooted and no yellow triangle.
Hello,
I've never had a samsung, this should (I have yet to decide) be my first one and I've basically understood that samsung hates you and would put a camera facing the screen just to know you're not rooting it.
So I want my warranty and I wouldn't really like to spend money on app like the one for the flash counter because I think I will have this phone just for a short time
I've understood that someone called mrrobinson has managed to find a way to root without letting the flash counter know. But in his thread I've found files for all the possible existing usa carriers, but I have a normal i9300 for europe.
And so is there ANY way to root flash cwm without flash counter appearing?
And if I flash a rom with cwm no problem as usual, right?

No
But Triangle Away will remove custom rom count .
Flashing a stock rom and a factory reset will revert modified status to original .
So I want my warranty and I wouldn't really like to spend money on app like the one for the flash counter because I think I will have this phone just for a short time
In that case run on stock if you don't want to buy cheap apps .

That's not really the point. The fact is that it seems more legit to me to not meet flash counter instead of just canceling it.
But so there's nothing like that mrrobinson method for normal s3?
Thank you btw

Well it's regarding rooting.
I heard it opens up a world of opportunity with your smartphone, and some apps I really want are only available vain rooted phones. I have the Samsung galaxy s3 international version. It was originally from Australia if that matters at all. It is on 4.0.4. Anyways, being a noob to android more or less, and being a bit apprehensive (because I have no warranty and I cannot obtain another phone easily) I was wondering basically how risky it is to brick your phone in a) the process of rooting your phone. Is it common? If it does get bricked is it reversable by a restore or simply gone? Also after rooting, is there any upkeep or management I need to do to make sure my rooted phone does not screw up? And lastly. What is the safest and easiest way to root the international quad core gs3 on ics. Thank you to everyone for your time

Well, most you could pick up be reading a bit, everything is already explained around here but since i was in your shoes very recently:
- there's always a risk. You need to be aware of that. That said, most cases that actually go wrong it's usually user's fault who failed to follow instructions closely. So read them. And read some more. And then read again just to make sure. And then i'd read again.
I used this very recent method from chainfire (salute and donate to the man if you like and can, he deserves it) to root my 4.0.4 international GT-I9300 S3:
http://forum.xda-developers.com/showthread.php?t=1957273
Triangled away next and everything worked like a charm. This preserves everything as stock as possible just adding root to your phone.
- from what i can tell, as long as you don't do anything that messes with the bootloader, you can always recover from a procedure gone wrong. Just disconnect, remove battery, insert and try again. Rebooting the computer or changing usb ports usually helps too (on odin).
- after rooting successfully, the very first thing you should do is backup your /efs folder. This is easy, just pick up root explorer or some other file manager that allows exploring you root (/), go up in your folders until you get to / look for the efs folder and just copy it (NOT MOVE) elsewhere (sd card, external sd, your computer preferably, whatever, just have that safe). This will come in handy in case you lose your imei at some point. Just restore this folder's contents and you're good to go. If that happens and you don't have a backup, it's a f'ing pain you can do well without.
- anything else root related is just common sense. Since you have the potential to screw up your entire phone with root permissions (this is why you don't have them in the first place), if an app pops up asking for root permissions, be sure what it is before allowing. If you're not sure, you can always deny first and allow later in the superuser app.
- you can also look into backing up with nandroid. You can think of this as an image of your entire phone. With this you can restore your phone to the same state it was when you did it. Useful when something went wrong and your phone doesn't boot anymore or you just wanted to try new roms with the option of coming back to what you had before. Not sure how you do it on the S3 still, but it usually requires a modified recovery like CWM. The method to root above doesn't install one though, it preserves what you had. Check this instead if you're interested:

Thankyou very much to everyone who has read and replied to this. 3 more minor questions. Is there a way to first update my phone to jellybean 4.1 via Odin or something like that? Or is this possible after root, because I don't want to stay on ics. Also what exactly happens if I update while rooted. Does it wipe or unroot my phone or the like? Also should my phone be in use debugging, and lastly what does it mean to unlock my bootloaders? That was more than 3 questions sorry thanks again

1) You don't need to root to update to JB.
Just download any ROM you want from http://samsung-updates.com/device/?id=GT-I9300 (I recommend the UK unbranded ROM, BTU) then use Odin3 to flash it to your devices. Search the forums for specific instructions on this procedure. I'll just tell that it takes no more than 2-3 minutes.
2) If you're going to root, I suggest you do it beforehand, by flashing a kernel like Siyah (in ICS), and then proceed to flashing the stock JB ROM, HOWEVER, instead of using Odin3, you will use MobileOdion (available from Play Store), because that way you'll have a fully rooted and stock device.
3) Using step 2 above, it will not wipe not unroot your phone. It is safe and retains all your settings. That is the beauty of MobileOdin. There is a free version.
If you root and THEN install via Odin (PC), then you'll lose root, but not your settings.
In either case, you only wipe the device IF YOU WANT TO.
So, the best option is to:
a) Install SiyahKernel using Odin3 (PC)
b) Download the JB BTU ROM from http://samsung-updates.com/device/?id=GT-I9300
c) Extract the .md5 from the ZIP file and move it to the device's ext. sd card
d) Install MobileOdin in the device
e) Use MobileOdin to flash the .md5 you moved to it in step (c)
f) install TriangleAway (download from XDA) and run it to reset binary counter (which got incremented in step [a] )
Results: rooted, JB, stock, all settins retained, no binary counter increment
Simonetti2011 I have been searching the internet here in New Zealand and that has been the best answer I have found so far!
I do have a slight question thought. I live in New Zealand and have the GT-I9300T model of the GS3 and I'm wanting to install the international unbranded rom for that I can get updates faster (here in NZ it takes months and months to get updates)
I downloaded the International UK unbranded firmware 4.0.4 and was going to flash that rom onto my phone then upgrade to jelly bean via kies but have since relised I should just download the jellybean UK firmware straight away. Do you by any chance havea link to the firmware that I would need, I noticed there were a few different versions.
Also about the CSC, would I need to do any changes?
Many many thanks in advance, Sorry for hijacking this thread, just figured I was on the same pages as the OP

Thanks!
The 9300T and the 9300 are NOT the same device, therefore they use different firmware (ROM). The ROMs for the 9300T are here: http://samsung-updates.com/device/?id=GT-I9300T
I don't think there is a 9300T ROM for the UK, since the model released there is the 9300 (non-T).
It seems that either Samsung-updates hasn't indexed any ROMs for your model or they haven't been released.
About CSC: just don't worry about it... download and flash any ROM you want for your specific model and don't worry. If you don't like it, just download and flash another one.
Thanks heaps for that!
I actually just tried the UK unbranded rom that was for the i9300 on my i9300T and suprisingly everything seems to work ok so far (phone calls, txting, 3g etc)
Thankyou to everyone!
Thank you for your responses to my post regarding rooting my s3. They were very helpful. i succesfully rooted via chainfire cf auto root for the I9300 model without problem. Just one last question, I have been searching around a bit and some people are saying that flashing the jellybean firmware via odin, is not a perfect copy.. i mean some say they have been experiencing very minor problems here and there. So, if i update to the uk firmware on jelly bean via odin or mobile odin, and i experience some problems, can i still get the official ota update or jellybean 4.1 via kies when it is released? Thanks again for your help. Im pretty new to this android stuff
I just got a Note 1 i717, currently locked to Rogers (I live in Canada), spent some hours to read about rooting Note 1 to work with Wind/Mobilicity, I'm new, Can you guys please tell me all I have to do is rooting the Note 1 to make it works with Wind/Mobilicity? do I have to have an Sim-unlocked Note 1 to start rooting?
I find this method is quite easy and safe, probably the best method to root Note 1, another question is can I update or install another rom after rooting and it still works with Wind/Mobilicity?

In order to use a carrier locked device on a different carrier, you have to remove the SIM lock. There's lots of ways to obtain the lock code. Usually calling the carrier is fast and cheapest. Or you can Google search for how to remove it.
Rooting is totally different then unlocking. Rooting doesn't affect what carrier your device will work on. Roms don't affect this either unless the rom installs a modem. Modems are what allow you to connect to different carriers. I'm unfamiliar with what modems work on wind/mobilicity but I remember reading a post on it here once. You'll have to search for it.

I am using a bell note with mobilicity. You need tp unlock your phone in order to use with mobilicity.
For rooting, i flashed twrp recovery using odin v1.85. Once, you have twrp recovery, you can flash superuser.i used superuser v94. You can get twrp recovery from goomanager too. Once you are rooted. You need to flash modem. There are many modems available. You just have to find right one for you.

You don't need root access to flash any modem or rom.
You need to unlock from carrier to use other carriers sim card. This can be done by ourchasing a code from ebay.
You will need to flash a modem that will let you access the frequencies\bands wind uses.
Don't quote, reply. If you quote, edit.
No Honestly lets chit chat about it what is a good modem for mobilicity because I havn't seen one yet that doesn't drop and require reboots 10 min+ wait while it rediscovers all the various band connections. I want to know if anyone has a good experience with AWS 1700 + 2100 on the note since gingerbread/ics (a little). I am thinking of giving it up because I use mobilicity / and wind in the past and it really isn't a functioning phone anymore because of the magivered modem from times long ago. All the new radios don't work because they havn't been modded to get the other bands ...
So good luck, but I think it is more a toy now than a phone.
Also I would like to point out that all the work that was done a year back was great and thanks to everyone involved.

so which rom you are using to make this work with Wind/Mobilicity? I already rooted and have recovery rom, but i dont know which rom to install. I have tried T-mobile rom but it did not work.
Would you like to share more detail how you managed to get it to work
What rom have you used, I m getting no signal at this point and lost IMEI number
Right so, this is my first post so I'm very new here.
I have a Samsung S2 (I9100) which I rooted using Framaroot. I then flashed CM 10.1.3 on my phone. I also flashed the DorimanX 9.41 kernel. I want to return my phone to stock everything. Basically, as it was when it came out of the box. I want to do this because I might return it to warranty soon. I know the steps to do. However, I need to understand a few things:
Is Triangle Away safe if I use it correctly?
When I flash the stock firmware, will I be able to receive OTA updates or will all of my updates need to be from Odin?
If I want to restore my warranty, does my phone need to have the carrier branded firmware? I am going to get carrier-branded firmware anyway but I am just wondering.
My baseband version is I9100XXLPH. My carrier is T-Mobile UK. When I go to SamMobile, I get this:
GT-I9100 United Kingdom (T-Mobile) 2013 June 4.1.2 I9100XWLSY I9100TMULS8
If my baseband version is I9100XXLPH, does this mean that this firmware is not correct for my phone?
Thanks for the help!
1) Well yes, like any flash there's that 0.0000001% something will go wrong. You can't remove that risk regardless of what anyone might tell you. If that frightens you, best not flash anything at all. Ever.
2) If you go back to stock, you should be able to get OTA updates OK, but sometimes it doesn't always work out this way. It's just as easy to flash your stock updates via Odin if you find OTA updates won't happen for whatever reason (flashing a 3 part firmware with CSC when you go back to stock seems to make it more likely OTA updates happen smoothly after).
3) If I was returning a phone for a warranty claim, yes, I'd put the latest stock firmware on for my carrier.
4) Forget basebands (which is your modem & not really relevant to anything) or anything else, choose the latest firmware they have for your carrier, flash that.
Thanks very much. However, when using Triangle Away, is there ANYTHING I can do to increase the chances of a successful reset? Also, will having used Framaroot change anything?
I've never had any problems using it (have used it a number of times/on different devices) & am not aware of anything you can do to try and 'maximise' your chances of it working (it should work for most people/most of the time), other than reading thread devoted to it on here thoroughly if you're genuinely nervous about it; other people's experiences in the thread might yield some useful info.
The root method shouldn't have a great deal of bearing on anything, but I'm not a developer so I'm not familiar with the 'inner workings' of how Framaroot injects Su & Busybox onto the phone/whether it does anything materially different compared to other root methods that might interfere with Triangle Away. I don't believe it does based on I can't remember anyone posting in the two yrs I've been coming here saying 'Triangle Away wouldn't work because I used X root method'.
Put it this way, if worse came to worse, if Triangle Away refused to work/reset the flash counter, you could always go back to Gingerbread stock, reset the flash counter with a jig, then flash the latest stock firmware & sent it in for warranty service.
Triangle Away is quick/simple/works most of the time, but that's not the only option you have if it won't work & you absolutely must reset the flash counter.
Thanks for all the advice. One more question though , is Triangle Away compatible with all ROMs and kernels? And (hopefully) final question, do I only wipe data on recovery or do I also wipe cache?
It's I9100 compatible, so yes, it is.

OP - You're starting to overthink/ovecomplicate this. There's no need to. Reset the counter, flash stock, done.
Okay. It's just that the warnings on the Triangle Away app are a bit scary and both times I've flashed with Odin, I've been stuck in a bootloop. Anyway, hopefully, I'll have stock JB up and running before Monday.

Trust me, you'll be fine (never trust someone who says 'trust me' )
When should I wipe data, before or after flash?
After.
Okay, thanks a lot. Just need to make a note of which apps I have installed so I can reinstall them afterwards. Also, is it possible to backup my messages and call logs?
Yes, titanium back up pro & similar.

But Titanium Backup doesn't work without root. After going back to stock, I'm going to stay unrooted for a while. Also, I don't want to backup apps.
Notice that I included "similar" over there.
