[Q] how to entirely go back to stock? - Android Q&A, Help & Troubleshooting

hi everyone,
Like you guys probably noticed I´m a new member here at xda.
I just got my new phone, it´s a Galaxy gio .
So anyway, i´d like to root, flash a kernel and put a custom rom on the phone,
but my concern here is, what happens if I have to send it back to the store, will they take it back and accept my warranty if they found out i have been tampering with the software?
SO I´ve figured this out:
Action >> Go back to stock
root >> unroot available
flash custom kernel >> ???
flash custom rom >> flash stock firmware ???
I probably will not use a custom recovery since i found out it´s actually very hard to go back to stock.
So my main question is,
Will flashing stock firmware give me an stock rom, and will this also give me an stock kernel?
if not, what actions should I take if I want to have my stock kernel?
and, did anyone send their phone back to the store with something custom on it, did it void your warranty?
thanks anyway,
the gentleman.

i´ve read a bit about the subject and found out that if i flash the stock firmware this will mean both the rom and the kernel will be stock again.
Is this right?

Yes, flashing your stock rom will return your device to stock (including the kernel). If you root your device, then your warranty is voided (but they don't have to know ). If you are returning it under warranty, make sure your device is back to stock or impossible to turn on (drown it ).

Bump..

Another good way is get an aftermarket charger, cut the end off, expose the wires and stick them into your charging port. Easy way to fry the motherboard!

[Q] guarantee

Do i lose my guarantee if i install custom ROM or downgrade? Cus i have 2 years guarantee
I don't know the answer of your question
But I think the answer is no
Of course you will. But only if they find out, there are reports that some people could use guarantee even if they have rooted phone and custom rom. But, manual says that you will lose it.
I was slightly confused by your question... then it struck me that you meant warranty XD
Tasssadar is right, it's only when they find out that you will lose it. There are many methods to revert it back to stock, so there isn't much risk in performing custom recovery.
Hello,
I restore my original rom and I have only to remove the custom recovery menu to return my phone in original state. I want to return in original state because I need of waranty service. So can someone help to remove custom recovery menu? I think that my USB port on phone is brick and I have problem with display.

You don't need to unroot it - rooting does not void the warranty. Putting a custom ROM on it, however, does. You need to flash back a stock ROM. Both branded and unbranded versions can be found in the xda bookmarks page in my signature. The threads also have very clear instructions on how to flash them.
The wifi issue may well be solved by flashing a stock ROM, so don't send it back till you've tried that and checked it again.
Good luck
If you want, I can provide you a stock recovery package, which will put the phone on the complete stock
The package is GB 2.3.4 based on XXKH3 and multi-CSC OXAKH3. It includes a .PIT file, CODE.tar, PHONE .tar, MODEM .tar. But if you do return the phone, you'll need to change the CSC which is set to default to KOR. You'll want to change to XEU.

I was sure that the letter sent out by Samsung mentioned rooting as voiding warranty .Speifically instructed techs to look for apps that required root .

I didn't know that (obviously, from my comment), but I don't see how they can justify it since you're not doing anything to the phone other than "installing" something on it. I guess they could argue that rooting allows you to perform commands that you otherwise couldn't perform, and they could damage the phone, but than a factory reset would cure it.
Not sure they could get away with that if pressed, but who knows. It's still worth the "unroot" if that's what they say.
Might they also look at the custom kernel count? In which case you will need a usb jigg.
Thanks everyone...lemme install a stock rom & try giving it at service center

[Q] Help with rooting

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.

[Q] ROOT for Galaxy S2 ICS 4.0.3 questions

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.

Root, I'm a samsung root noob!

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
http://forum.xda-developers.com/showthread.php?t=1728441 This for example, would it work? Would I be able to flash cwm then without that counter?
