Hello, i am using Triangle Away on my I9300 it is not working with CM11 the count will be 1 what now?
Sorry tot my bad English i am Dutch
Cheers Plukkies
You MUST be on stock, recovery alzó, ROM in order to get triangleaway to work (not to mention stock kernel)
Have you a tutorial
And how make a backup i am new
Simple.
Flash stock ROM, preferably with ODIN, root the phone, and use triangleaway app.
As simple as it sounds
They all say that you first need to use Triangle Away
Look.
You can use Triangleaway ALWAYS on STOCK ROM (or based).
If you try in CM ROM will not work.
It's already stated in the app, that you must be on STOCK ROM, kernel, and recovery.
Is it important that I have the IMEI backup
Thread moved to proper section.
Doesn't harm to have An IMEI backup.
But I encourage you to leave the phone as it is if you are not An advanced user
The problem is a month ago, I thought I install CM for fun using the Windows installer but now I want it back. But I can not get out because I'm not an experienced user
I'm very stupid

You only need to reset the counter when sending it to samsung for warranty other wise there is no reason to worry about it.

Tell me how.
Read the sticky, like you've been told.
Thanks for the effort, I will keep CM11. Because I prefer a video tutorial but they all start with Triangle Away and only then stock rom.

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:
CF-Root-SGS2_XX_OXA_KG1-v4.1-CWM4.zip

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.

OK, you are helped me a lot, thank you very much!
I hope someone will help me like you one day when I maybe have to back on original to get my warranty back.
Cheers!
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

I'm rooted now!
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 Community!
So I had my Desire for quite long time, december 2010, and I rooted it and installed CM on it. When the CM team announced the CM9 devices I was heartbroken: no update for my sweet desire So a week ago I bought my S3!!! I LOVE IT! I just miss the old CM Yes I like touchwiz and stuff, but CM and rooting is just so much more powerful for a device like that(and desire was horrible with stock lol).
So my actual question is:
Am I still going to use clockworkmod?
Can I brick my phone?
Can I unroot my s3 if I root it?
If I brick the phone, is there any way to unbrick it?
tips and hints?
from nervous me
In order (to the best of my current knowledge)
Yes you will still be using CWM unless you flash EXT4
I believe you can like always but if you read everything twice and follow it to the line you should be safe
As far as I'm aware there is no un-root method yet but there will be
Again I don't think there is un-brick method yet but there will be, but the chances of bricking are so low like I said before if you pay attention you should be fine
Hope this helps.
Rooted my phone few days after i got the phone on may 25th. Been installing and testing Omega Roms for more than 2 weeks. Tested few different kernels and now o/c'd the device to 1800mhz. So far so good.

What about warrenty and stuff like that?
I heard about something called TriangleAway, it removes the flash counter to 0. But if the phone is rooted, how can the triangleaway help?
If the phone needs to be repaired, what about that?
Thx again
When you un-root the device you can use triangle away to remove the flash counter so the phone will look like its never been touched it's pretty awesome

Correction: You can't unroot the phone and use triangle away but once you use triangle away use MOBILE ODIN (this doesn't add to counter) to flash stock rom then the phone gets unrooted and everything gets back to factory default.
Hello!
Well, I got my S3 since a week ago, from my local carrier, and what so GREAT phone!!!... but, well as with my previous phones I woulkd like to install something more good custom Rom...
However, I bought my previous phones second hand, so, I was never minded about save the original firmware, since I didnt had a warranty to care about... but my S3 is new on a 2 year plan and I had a minimun 1 year warranty to care, so if I root or install a custom rom without have a backup of my exact local firmware version to reflash I would not have warranty ( and by this same reason no other carrier/country firmware would work as backup for my S3...)
So, I would like to ask if may be possible some help (for noob level, please, since I am somewhat new in Samsung issues ) , in order to what could be a good method make a full local backup of my phone,so since it is no root by now, and I wonder and suppose that if I root, if may be possible that the backup may save the rooted status of my phone and in case of a restore the root status may show that the phone was tweaked...
Thanks in advance for kind attention and help.
Best regards!

well, thanks for take time to read and post, and please dont take me wrong, but, IMO is the type of answer that I often see in other post/forums and IMO barely usefull, but anyway it put me on seaching again, and so, I realize that before I post this thread, I was lost in others posts that didnt have the exactly info, so, Thanks again for take time to answer.
Anyway, I am reading by now, but if may be useful for another noob, seems that Ktools may be the utility for the backup.
Best regards to all!
ok. ill try to help as much as i can besides asking you to search.
1st. you must get rooted using chainfires method. you find the thread under original android development.
2nd. once you have rooted and followed those instructions, you will end with an CWM application in the phone.
3rd. open CWM choose boot to recovery mode.
4th. from there choose backup and restore. then backup. once done your backup will be done and stored in your sd card.
if you are going to restore this phone due to some errors in flashing roms or problems on phone after flashing new stuff its fine.
but if you are talking about warranty claims, you cant do a restore. you need to make sure custom binary counter is already at 0 by using triangleaway from chainfire, then flash a stock firmware using odin , then send for warranty claim.
I got one question that no has been able to answer.
I'm using stock touchwiz launcher that came with the phone. If I backup with titanium, how do I restore my home screen layout?
I can restore all the apps but the home screen layout doesnt restore.

You cannot save the layout unfortunately. If you use other 3rd party launchers, they usually have the Back up option..

They say not to restore system data with titanium. Though I seen that touchwiz is backed up in system data. If I restore the touchwiz backup, will that restore my homescreen layout?

Possible but as advised TB restore system your risk .
CWM will not back up you original firmware in full as you now have Rooted phone backed up and you will need to reflash stock kernel .
Simpler to download your original firmware and flash via Odin .
Firmware found in the stock rom threads or via CHECKFUS >

Hi ad_ek!
Well, That's is for sure a polite and really usefull answer! I really appreciate that.
So, Thank You very much for Your help, and your instructions are very clear to my purposes, and by the way, I will search by my own for more info about the steps and resources that You mention, but in fact is a very concise HowTo to follow.
In special I would like to try to study in detail the info on You last comment, about setting binary counter to 0 with triangleaway since until today I didnt know before about triangleaway resource...so, since this detail seems the most important for my purposse, if I would like to have a lifeguard, that may allow recover my carrier stock rom, to a minimun level, that I may have a chance, that may, at least, allow to try a warranty claim if I may need it in the next 2 years...so, wonderfull your help.
Thanks also to the others that are posting about this thread and best regards to all.

Hi there, I have been reading around on this forum for some time now but this is my first post and I have a few questions about rooting my UK version of the Galaxy S3.
Just to clarify, I am NOT asking how to root a phone, I already know exactly how to do this and the risks involved etc etc, I just want to know a couple of things about what happens after the root.
1. When a nandroid backup is performed after the phone is rooted, is ROM that is backed up COMPLETELY standard or does it have some remains of the root included? i.e. if I wanted to go back to my stock ROM, will it be exactly as it was or will the phone still have some remains of the root in the backup?
2. Does rooting on its own increase the flash counter? I know flashing a new ROM does, but am unsure whether rooting on its own does this (and yes, I am already aware of TriangleAway )
3. In referance to question 1, does reflashing a completely stock ROM remove the root access? (just in case it has to go back for repairs etc).
4. After rooting does anything change with the stock functions of the phone? e.g. will play store still work ok, will apps still update officially through play store etc. Adding to this, will flashing a custom ROM disable these functions? (the ROM I am possibly looking to install is CM)
Thanks in advance to anyone that can help, I understand a couple of these may be stupid questions but I've searched for a long time and as this will be my first root I just want to be absolutely sure what the process involves

1. Whe you perform a nandroid backup..everything gets backedup..if you are on a rooted rom when doing a backup (you have to be rooted to do this) your rom will have the root when you install the backup again... to remove the root you will have to unroot your device using means given in various thread...you might have to install a stock firmware in download mode using Odin..even the stock ROM you flash via recovery will have root
2. Any action performed in the download mode will increase your flash counter..rooting is done in download mode via Odin so it increases your flash counter..custom roms are flashed in recovery so they dont increase your flash counter..
3. Read point 1 again
4.The functions present after installing a custom ROM depends upon the ROM..read the OP before flashing (ALWAYS)..but if you are not flashing a test ROM..you will get all the fuctions.. in CM9/10 you will get all the google options..you will loose Samsung specific functions..Smart Stay, Smart Beam etc.
Hope it helped...
Thanks for your reply, that helped a lot
Just one more thing in response to your answer about my 1st question - I am currently on the Three network and it comes with a couple of things as standard in the ROM, so is there any way to backup the ROM without being rooted, just in case it has to go back to Three for repair? Or is there somewhere where I can download a completely stock Three branded ROM to keep safe in case I need it in the future?

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.

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?
