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.

Hey everyone,
First post, n00b question - please be gentle.
First, I'll start with a positive. I have come from using an iPhone, and I was quiet comfortable with jailbreaking and cydia. I now have a Samsung Galaxy S 2 / II (GT-I9100T). I am from Australia, and on the Telstra network. Whoever is in the same boat would know it is quiet an adjustment, but you can root! (if you wanted to know).
I followed this persons 3 part guide and with sucess:
I cannot post the link but it is on YouTube and the video title is:
How To Root The Samsung Galaxy S II - Part 1
How To Root The Samsung Galaxy S II - Part 2
How To Root The Samsung Galaxy S II - Part 3
Username is mattj101101
I had Android 2.3.3 installed.
Second part is a question, is there any debranding roms / kernals that is ok for the GT-I9100T? I have tried the *#272*IMEI# but it only had 'Preconfig - TEL'
My phones info:
PDA: 19100TDVKF4
PHONE: I9100TDVKF2
CSC: I9100TTELFK3
My Kernal version, after the root is 2.6.35.7-I9100XWKDD-CL161513root<insertATsymbol>DELL103 #2
Hopefully with these answers I can help other fellow people out with this particular model (that are sold in Australia). Also if someone has the stock Telstra rom for re-flashing (if needed for warrenty) please point me in the right direction.
Thank-you.
Hey,
Ive got the GT-I9100T from Vodafone (both can run on the telstra bandwidth now ) and have had no issues flashing most roms. Only thing you may notice is the new modems aren't as good as the stock ones you currently have, so you may need to reflash the original modem through odin to get the best support.
Before you do flash though, make sure you back up your /efs folder, it contains the bin files for your IMEI for your phone, and people have reported flashing a rom can change that, so beware! also, before you do flash, try find the stock telstra rom for your phone incase you need to reflash. There are a few threads about it all, so good luck
The i9100T can use i9100 roms, but it will change the product code to i9100.
Easiest way to root is using CF-root, match the part of the version number in bold "PDA: 19100TDVKF4"
My phones info:
PDA: The rom/kernel
PHONE: The modem/radio, responsable for signal quality and speed, you dont need to match this to rom version, and the best way to find a good one is to test different ones.
CSC: APN settings and bundles apps, no need to match this, but if you do chose to all you may have todo is enter your APN settings for internet and MMS manually.
You can flash any rom onto any SGS2 via odin, see this guide, that will debrand etc.
Also, you rooted using a very old insecure kernel, people have had random reboots with that one, I suggest you flash back your stock kernel (you will keep root) or flash a version of cf-root (you will gain clockworkmod recovery, a way to flash roms/etc from your phone, and nandroid, a whole phone backup system, like snapshots)
I would recommend flashing DarkyRom2 on your S2. Runs fast, stable and great battery life. It roots your phone as well and changes your kernel to SuperCore which has a lot of optimisations.
Instructions:
Since you're not rooted (stock firmware/kernel)
1. Flash SuperCore_1.7.tar with Odin (put in PDA and do NOT tick repartition)
2. Get DarkyROM2 Tool and Superuser from market
3. Upload DarkyROM2_XXKH3_Base_R2.zip to SD-Card (INTERNAL)
4. Open DarkyROM2 tool. Accept SuperUser access request notification (this confirms you are rooted.
4. Under the DarkyRom tab, be sure "Wipe User data" is selected AND "INSTALL MODEM" is NOT SELECTED. (this will wipe everything from your phone but keep your stock KF4 modem. Any other modem causes signal problems for our I-9100T. )
5. No need to select "Install Kernel" Since SuperCore 1.7 is already installed.
5. Go back to the General Tab and use "Flash/Install File from SDCARD" to browse to and install DarkyROM2_XXKH3_Base_R2.zip
6. Wait for the phone to reboot and flash the new firmware
Get the files here:
http://www.darkyrom.com/community/index.php?threads/rom-cwm-sgs2-darkyrom2-kh3-base.4950/
I modified the instructions given on that link and posted it above for you since it's a little different for our I-9100T phones.

Interestingly, I just purchased a SGS2 here in Thailand (I'm also an Aussie) and the model of the phone is GT-I9100T.
Unfortunately I cannot seem to find a KL2 kernel for CF-Root to patch it with... any suggestions?
Also, the site that held all the OEM kernels (MultiUpload) for download is now showing a "Shut down by the FBI" logo : )
As long as you're certain you've got a I9100T, use the KL1 CFRoot kernel. Will work fine.

My phone details are as follows:
Model: GT-I9100T
Android: 2.3.6
Baseband: I9100TDCKL1
Kernel: 2.6.35.7-I9100TDCKL2-CL767350 [email protected]#2
Build: GINGERBREAD.DCKL2
This is not an Aussie phone such as the Telstra I9100T that I see spoken about.
I purchased this phone here in Thailand 3 days ago and I have a few questions.
1. Is there a way to backup the original kernel before rooting?
2. Will the KL1 kernal make me lose things such as Thai language options etc?
3. Any way to restore the KL2 kernel in the future?
Thanks for taking the time to reply!

1) Doubt it. And the only link for DCKL2/Thailand in Intra's official firmware thread is dead as it was MegaUpload, and he more than likely won't have a backup (you could always ask him tho). Search around elsewhere online, you might find a copy of this kernel somewhere.
2) I don't know for certain, but I don't think so. I would have thought something like language would be more firmware-related.
3) Refer to 1) I don't see why you'd need to ? In order to get warranty service from Samsung, all you'd need to do is flash the most recent firmware available for your phone (for all they know you could easily have got this from an OTA update via Kies), do a factory reset/make sure there's no apps left on your phone that could tip off whomever repairs it that the phone was rooted, and use a jig to reset the flash counter. Obviously there are no rolled gold guarantees with getting warranty service once you've voided same by rooting the phone/running non-stock firmware firmware on it, tho.

I was just worried it might stop future updates to ICS or similar via Kies.
At least I think I've managed to find another copy of the latest kernal on a site other than MegaUpload...
It's at 50% and counting : )
3) Refer to 1) I don't see why you'd need to ? In order to get warranty service
Running a CFRoot kernel over stock firmware should still allow you to receive OTA updates via Kies. If you find it doesn't, simply use Checkfus (search for it on here), it allows you to find/download the latest firmware for your phone/country that you'd normally get via Kies.
Really ? Cool Might wanna post a linky to your source over in Intra's thread. I'm sure there will be other people who might need it at some stage.

Ok so would you believe...
I ran the guide from Intra.
Installed an insecure ROM and then ran SuperOneClick and was rooted.
I restored the OEM kernel that I found online and BINGO - UNROOTED!
I repeated the procedure just to check everything again... same deal!
Phone is currently unrooted again...

Yeah, if you flash an original (unrooted) kernel over your rooted kernel you'll lose root.
There's a procedure for removing the yellow warning triangle at boot in the CFRoot thread & also retaining root, but I found it too fiddly when I first rooted my phone so I simply bought a jig & did it that way.
I can't speak for anything to do with SuperOneClick as I've never used it.

As I said, I have no idea whatsoever about anything to do with SuperOneClick. If you want a rooted phone minus the yellow warning triangle at boot without fiddling around, root it with a CFRoot kernel, buy a $3 jig from eBay, done.
So far as Kies not working, you could try uninstalling/reinstalling Kies, or simply use Checkfus as I've said previously. Me, I'd use Checkfus. Quick, easy & like the paragraph above, no fiddling around.
Edit to add - Yes, obviously Kies won't work if you're running an "insecure rom" as per your post above. I presume you mean a custom rom you found somewhere on here or elsewhere ? One of my earlier posts did say Kies should (not always) work if you're running a rooted kernel over a stock Samsung rom. If you're running a non-stock rom Kies won't work.

Ditch Kies there is a better alternative out there. MyphoneExplore, do a seach via google. You'll also need to get the app client software from the android market. I use it to synch my work Outlook Calendar to my phone. You can also back up your contacts, sms and call records.

Edit: I tried CF-Root KL3 (wanted KL2) and it seems fine so far.
I have root and everything else seems the same (Thai language support etc.)
I'll keep you posted : )
Thanks for taking the time to deal with my issues!
Hope I can do the same for some others on this Forum in the future.
I'd not heard of Checkfus so I'll give that a try, thanks : )
There's no CF-Root to match my phone exactly but I guess there's nothing to lose now by trying something close : P
I ordered the jig almost a week before getting the phone but it seems the postage to Thailand is sloooow.
I'm running a stock ROM and unrooted but Kies is still misbehaving.

Something may have borked so far as the CSC goes (which tells Kies, the Market, etc where you are). I did say you should be able to use Kies, you're not the first person to have problems with it after rooting
Personally speaking, I've never used Kies & almost certainly won't use it. Ever. Custom roms/kernels are a piece of you know what to flash via CWRecovery (or Odin for that matter), and official firmware updates are easy to get with Checkfus & flash via Odin if I ever have to go down that path for warranty purposes or whatever.
Kies is a truly awful piece of software

Hello.
I have stock unrooted Galaxy S2 and I want root and put custom ROM (Turkbey ROM probably).
Android 2.3.5
Baseband version
I9100BUKI1
Kernel version
2.6.35.7-I9100BUKJ3-CL647431
[email protected] #2
Bulid number
GINGERBREAD.BUKJ3
So, wich metod I must use for rooting?
CF-Root?
I don't wanna stay on stock ROM, so it will everything works fine if I root with CF Root, make backup and then flash custom ROM? I'm asking because CF Root is a kernel, so I don't know what happens if I change ROM and kernel.
Cheers
Yep that all sounds good. Great to see you've got it all planned out
So yeah, firstly root the phone with the CFRoot kernel that matches your baseband. And then, as you said, do a Nandroid backup in CWRecovery before you flash a custom rom so you will have a copy of your setup as close to stock as possible if something doesn't go right/you don't like the custom rom you flash.
From there, you can flash whatever custom rom you want. The rom you flash will have its own kernel & will overwrite the CFRoot kernel. You can also use kernels other than the one supplied with many roms. There are quite a few kernels in the development sections you can read up on & use. You're not stuck with just using the kernel that is supplied with the rom you flash
I did mine with SuperOneClick.
Took all of 5 minutes and required no effort or input from me which = less chance for human error.
Was quite easy so I recommend that.
Thanks guys for reply!

In CF Root thread says:
Go to Settings -> About phone -> Kernel Version. Note the string present there:
2.6.35.7-I9100XXKG1-CL349526
What matters most (KG1) in this case, is in bold. Try to find the matching file under downloads:

My kernel is KJ3, so I must use KJ3 kernel from this post, right?
I just want to know one more thing.. why people remove yellow triangle (it's shows on startup)? Just because it annoying or it's something else?
Maybe one day I will must go back on stock unrooted software and reset counter.
Will it work USB Jig if I restore nandroid backup with these 2.3.5 Gingerbread, and then unroot?
You can root and unroot with superoneclick with the click of a button. Removing the fear of doing it wrong manually.
I cant post the link but if you google it you will find it easily.
But yes that is the right cfroot you picked out in your last post.
Yep that's exactly right. You can match your kernel. I've also seen people match the baseband as well. Actually, now that I remember, I matched my kernel too and it worked, so yeah definitely use KJ3.
Yes people remove the triangle because it's annoying. Makes no difference to the operation of the phone whatsoever. You can use the method in the CFRoot thread to remove it (fiddly) or use a jig.
Yep if you ever need to send the phone in for warranty purposes, go back to stock & reset the counter with a jig. You might find the jig won't work immediately with 2.3.6 in particular (not sure about 2.3.5), in that case you can flash the old bootloader (available in this thread) & then the jig will work.
I've used the jig successfully with Miui which is 2.3.7 but obviously I have the old bootloader. As above, if the jig doesn't work, flash the old bootloader. Yes, I think the jig will more than likely work if you reflash the Nandroid backup you make of your current setup before you flash a stock rom.

No probs man
Yeah, if you have any dramas if you ever go back to stock, whether you do a restore of your current setup or flash a stock rom via Odin, I'm sure there will be plenty of people around to help. You did your research with the rooting/doing a backup immediately after you root which is really good on your part, so I don't think you'd have any problems going back to stock at all

via CF-Root, everything was fine, except this:
When I put my mobile into download mode, custom binary mode was 4!
So guy who sell me galaxy s2 was on custom ROM, but he didn't reset counter.
It's not big deal now, but I didn't know that and I could be suprised if I was on Samsung service.
Cool. Glad the root went smoothly
Really ? Yeah he's obviously had a go at flashing the phone before he sold it to you. Maybe he flashed a custom rom or two, didn't like it/then & then went back to stock ? No biggie tho, you'll be able to reset the flash counter when you get your jig.

Hello fellow XDA user
I have recently bought a the I9100 internation version and I am really pleased, however I do know the power of a ROM and how much it could improve or brick your phone.
However I came from the Galaxy S i9000, I never managed to recover the phone, so it would be recognized by kies, it did recognize my phone, but it said that 'Kies didn't support any upgrades for it'. Meaning if I would like to return it for garantee reasons, the shop or manufacturer will see I have been messing with my phone, which excludes my warranty.
Therefore I wonderd if there was a possibility to install roms or root your phone and unroot it, so kies would regonize it again.
Thanks alot and feel free to suggest any rom

yes there is a way cfroot to which will give you superuser access and also CWM recovery by then swapping back to stock kernel will unroot also if you using odin to flash this wil increase binary counter look for a app called triangle away this will reset the binary counter but only works on ics.
this is just basics to answer quickly your question please still search within the sgs2 forum sections most of all new users questions have been answered and there is many guides for new users to refer to in development sections prior to installing customs roms etc

this is just basics to answer quickly your question please still search within the sgs2 forum sections most of all new users questions have been answered and there is many guides for new users to refer to in development sections prior to installing customs roms etc

I know about CF root .. but as I said before, I managed to restore the stock functionality of my Galaxy S, but I never managed to get support from Kies again. ('Kies doesn't support updates for your phone'). I don't know if the Galaxy S II method might diffrentiate from that .. but I do want to be on the safe side with my warranty and I don't want another bad to happen to my phone.
Quik Recap
1) Prepare Odin --> Go download Mode (Power + volume down + home button)
2) Flash Phone --> Odin --> Install CF Root Kernel
3) Mount Phone ---> USB --> Download Rom ---> Boot ClockWorkRecovery (Power + volume up + home button)
4) Enjoy Rom --> Enjoy Xda Power
5) How to Revert?, will kies regonize it and support it

Can someone please answer my post above, I really want to start modding, but I also want to be able to get back to an unrooted version with Kies support
Check out the links in my signature, especially the one about going back to stock. That should satisfy your request.
Long story short, reset your flash counter and flash stock rom. But make sure you READ
OK. The experience on here over the past 6 mths or so goes something like this. About 50% of people who go back to stock firmware for their region after using custom roms or stock firmware not for their region seem to be able to get OTA updates via Kies OK. For some reason(s), the other 50% or so of these people seem not to be able to get OTA updates to work despite flashing a full stock rom for their region (with correct CSC).
Why doesn't it seem to work for some people ? Who knows ? I don't think I've seen a single answer that could cover even a small majority of those cases.
Regardless, if you find you ever go back to stock with the intention of getting OTA firmware updates & they don't work, do what plenty of people on here do & flash them via Odin. Easy fixed.
The bottom line with warranties is this. The moment you start rooting your phone or flashing non-stock firmware on it, you should forget about/lose all expectations of warranty service/replacement should something go wrong with your phone. At the end of the day, you mess with your phone, why should Samsung/your telco foot the bill ?
Having said that, if you format everything, go back to stock & reset the flash counter, again, the experience on here is many people seem to get warranty service OK.
What you seem to be looking for is a 100% iron-clad guarantee.
There isn't any. If potentially borking your phone & having to pay to have it repaired/replaced yourself frightens you, best advice would be simply don't mess with it. Stay on stock. That's the only way you're getting 100% guarantees. If you've only ever been on stock/OTA updates & never rooted/flashed custom firmware and the phone borks, they pay to fix it.
Pretty simple really.
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:

Cheers dude, i'm sure everything will go well for you too.
Chance of a brick about .0001 % rising to 100% for those that are to lazy to read follow instructions .

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
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.

What does the cache do then?
Stores apps' info and other s#!t.
It's not mandatory to wipe per se, but it might help when going stock from custom and viceversa.
I told you, you're safe from the brick bug as long as you stay away from 4.0.4.
Sent from the little guy
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.
Sent from my GT-I9100.
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.
Sent from the little guy
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.
You really should hit the threads before you jump onto the flashing field.
Sent from the little guy
Thanks for the reply. Just two more questions:
If I do EVERYTHING correctly, is there any chance of a hard brick.
And, I tried following this guide (http://forum.xda-developers.com/showthread.php?t=1068193) but the commands it said to back up my efs folder didn't work. Could you recommend an efs backup tool?
