[Q] Return-To-Stock Clarification - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
Just to double check before I flash CF-Root, if I want to return to full stock including recovery, flashing a stock ROM without the PIT file will do so correct? I just want the option to return to a vanilla ROM and recovery if I choose.
I did search the forum, but it was all a bit vague.
Thanks!

You might want to get a Jig to reset the flash count.

I'm sorry, i'm new to flashing the S2. Flash count?

Samsung has now put a counter on the phone which helps sales staff and engineers to find out if the phone has been rooted of flashed before.

Ah I see, well, I haven't had to take any of my phones back for warranty work yet. This is more for my own peace of mind, I like to be able to return to full stock, completely clean. Many thanks for the quick response!

Flash your original saved rom or flash providers rom from dev thread or flash stock Samsung rom .

Hi all - similar question as I want to (potentially) return my SGS2 to stock before I sell it. I have already rooted & flashed ROM so familiar with CWM / Odin / etc. but am unsure which firmware I should be using. Is there a difference for US / UK devices; how do I decide which one to download from Intratech's link ?
I have a USB jig so will reset the flash count afterward.
TIA

Download the firmware that matches your original firmware .

That's what I was planning but can't find the bit of paper where I wrote that down
Any way of finding out by HW build / serial / etc. ? Phone was originally locked to T-Mobile but I SIM unlocked it.
I've seen on other threads that the Carphone Warehouse (CPW) firmware is unlocked so may be OK - any thoughts ?

Why can you not download the stock rom ????Or at least update to the initial rom via Kies .
If you factory reset your phone it reverts to the last installed firmware .Not the firmware the phone came with .

Look at the links at the start of the thread
Download a stock rom
Flash with odin
Factory reset will wipe data, it wont put the rom back onto a stock rom.

If phone is rooted you will see an application called Superuser .
If you want to root a non rooted phone you use the root link posted .
If you want to install a stock rom you use the link posted and look for a XEU or CPW rom in that post for UK use .
Generic XEU (UK)
Generic DBT (German)

[Q] how easy is it to roll-back (un-root)?

Hi all,
A quick question on how easy to roll back (un-root) and put back the stock ROM?
My current ROM is stock Telstra ROM. (just bought the phone today)
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
Build Info : Jun 21
I know how to roll back a HTC Desire - by installing the RUU image from HTC or use the PB99IMG.zip install method to remove "root" and put back into std ROM.
I have yet to root my SGS2. Reason to un-root and go back to stock ROM is for warranty purposes. you never know what will happen (for example, my desire decides to dies on me yesterday, had to put back stock ROM to submit for warranty claim).
thank you in advance

if i do not install any custom rom, therefore, the usb jig is not required, right?

Nope. Jig is only required to clear the custom Rom counter, in case you have to claim warranty and return the phone to Samsung. And also to force the phone in Download mode, if something bad happens while flashing custom ROM etc.
hey cad,
Made any headway here?
I just bought an SGS2 from Telstra as well and I have a similar phone to yours.
PDA: DVKF4
PHONE: DVKF2
CSC: TELKF3
I too would like to retain the stock kernel, firmware and csc.
If we root with an insecure kernel, how do we go back to stock kernel if it's not downloadable?
Could we just flash another kernel if we are making a warranty claim and hope they don't check?
I assume CSC is where all the Telstra crap is stored and once we get ROOT, we should be able to back this up out of \system

Usual is flash a relevant stock rom or older stock rom and update via Kies.

Hi all I new to all this so could someone point me in the right direction...
1. I need a noob friendly guide to explain what rooting is.
2. How to root.

Video tutorials would be healpful. Im comming from a HTC HD2 but it feels like the explanations were easier to find.
Thanks in advance.

[Q] Want to flash to completely Stock

Hello,
Sorry if this has been answered before. But I need to flash my SGS2 back to complete stock ROMs. It was locked to Orange before I started to play with it and had all their branding on it. I have also got CWM which I will need to remove.
I have also changed the modem, I think. I have no idea which one to re-install!
Thanks for any help that is given. (It needs to be done for a warrante return)

if you had a version with the new bootloader you need to flash the old bootloader in order to be able to reset the counter with the jig.
you should have written down what your stock firmware was...
Why are people consistently sorry if a question is already answered, but still insist on asking. Surely they know to googlise it.

Is there a Stock firmware I can download for my phone and make it 100% stock? If so, how do I know which one that is? Thanks.

What is your intension to going back to Stock? since you have no warantee issue..
enjoy any of the stable custom rom...
also you can check region wise firmwares releases here www.sammobile.com
You wont brick your phone by downloading the wrong region ROM. You can put any version from any country only if your phone model is I9100 and not I9100G or any of the AT&T or T-Mo ****!
Just go to about phone and see the build number and kernel and all, you'll probably find the rom and kernel.
Thank you, you two (JJEgam and frankimm) are the only ones that actually answered my question. Thanks again!

I want to sell my SGS2. What have I to do?

Ok, I need to sell it...I'm using kitchen ROMs since 2nd days of my phone but I bought a JIG too (In case of emergency) and my flash counter is still at 0
But I have some doubts...I don't care about warranty but now that I'm selling it I have to think about it: can I wipe everything on the phone and then flash a stock ICS Rom with Odin to restore warranty or my warranty is gone anyway..?
Thank you
If your custom counter is at 0 and you don't have the yellow triangle at start up, then flash an original stock rom for your region on to your phone using odin. This will restore your phone to stock. See the links in my signature for reference.
Hey
Jigs don't work with ICS and Triangle Away won't work on an unrooted Rom, too. Therefore you should get an official Samsung Gingerbread Rom. If you got your phone from a carrier download the rom appropriate to your carrier.
Flash this rom in Odin and afterwards set the flash counter to 0 with your jig (if needed). If this all worked you can now update your phone in Kies to ICS.

Ok that's great to know..but If i flash a stock rom my counter will not increase...right?
An official stock rom by Samsung will not increse your custom counter, as its offical and not custom.

Ok last question: any stock rom or only the one from the country where is my phone from?
Any should work, but it would be best to keep it authentic and use one from your region (and / or carrier if thats how your received it). There may be region specific settings such as modems which come with it and if you've got a UK firmware on an handset purchased in Italy i might look a little suspect.
Choice is yours ultimately
ok so..i don't remember which was mine..if TIM branded or no brand...or if was imported or not..any way to know it?
A quick glance on Intratechs site (last link in my sig) shows that Italian roms are marked with ITV. Oh by the way, youre using i9100 international right?
yes International, but I switched from many many roms...is there a way to know from where is my phone to restore its country firmware?...may sammobile helps me?
Not if the original purchaser does not have a clue ..
Flash local stock rom .
