[Q] Unlock or not ? - Galaxy S II Q&A, Help & Troubleshooting

Hello,
I am thinking about flashing Intratech´s latest Frankenstein Rom(XILA2) but my S2 is locked to Vodafone. Should I unlock before I flash or is it ok to flash a non Vodafone Rom even with the phone locked?
Thank´s

The carrier has nothing to do with whether the rom will work or not. Its more important whether the rom is made for your phone. However, if for example you live in one country and flash a rom from another, there could be some complications.

for carrier branded firmwares they are updated just as rapidly i guess

So in your opinion it doesn’t matter if the phone is locked or not, what matters is if the Rom includes your country. Right?
I want to flash Intratech´s Frankenstein Rom "PDA: XILA2| Modem/phone: XXKL1| CSC: XEUKH2", what should I pay attention to?
Thanks for the quick reply

[QUOTE=Mad_Rick;2150911, what matters is if the Rom includes your country. Right?
No any rom on any i9100 International will work .You may need to change CSC for local networks . likewise modem and language versions may not be relevant to you .
But it is easier to pick a firmware that has been issued for your area .
I want to flash Intratech´s Frankenstein Rom "PDA: XILA2| Modem/phone: XXKL1| CSC: XEUKH2", what should I pay attention to?
Following the instructions in the thread is all .
Warranty = flash stock rom or your branded network rom reset custom rom counter if above zero .
jje

I´m sorry guys I´m a complete noob to android and I am getting a little confused
What I’m understanding from your explanations is that I can leave my phone locked to Vodafone Portugal and flash any generic/unbranded rom because the lock state has no influence over what rom I flash. And when flashing a rom I must choose the right CSC for my country witch in my case should be "TPH..."(Portugal). Is that right?
If I flash Intratech´s Frankenstein Rom (PDA: XILA2| Modem/phone: XXKL1| CSC: XEUKH2) which doesn’t have a TPH... CSC can I flash a multiCSC package like OXXKE2 that includes TPH?
Thank you for your patience !!

Yes to all.
Unlock phone is to allow non carrier Sim cards to work.
Rooting allows the flashing of custom ROM, kernels, themes, mods, certain apps (root SU permission) etc.
Just flash back the required csc, you will loose you data, so backup to PC first.

Noob pretty confused about rooting/unlocking

First, I did read/search quite a bit, but I need some help to get started...
The Samsung will be released in Canada on July 14th, from Bell Canada. But I will be using the phone on a different compatible carrier (Telus).
Therefore I will need to unlock the phone, which seem doable with: http://forum.xda-developers.com/showthread.php?t=1064978
But before it seem I need to root the phone.
Ref. this thread: http://forum.xda-developers.com/showthread.php?t=1075278
This confuse me:
The stock kernels are to be used to restore the kernel version after rooting and are not needed for updating the firmware.
You do not need to root or unroot the device to update the firmware.
Click to expand...
Click to collapse
From what I understood, there seem to be the ROM: which seem to contain android (original or customized), what would the firmware and the kernel be?
Obviously, there is not likely to be a stock firmware from Bell on launch day. Is it needed to root the phone?
My end goal would be to: root the phone, keeping the original android on the phone, and unlocking it.
I can always buy an unlocked version for 100$ more.....
Thanks you

No pick a similar version root .

Rooted phone is no longer original firmware /android you have changed the kernel .

I am fine with voiding the warranty...
Can I use any of theses: http://forum.xda-developers.com/showthread.php?t=1075278 ? (As I think they are "official samsung" rom).
Can I apply a firmware that is in that list to my canadian Galaxy S2?
Well have to see what the differences are with the Bell version of the device before this question can be answered.
Edit : intratech has right of course.
If no hardware modifications :
If you have a branded operator firmware, you will need root to unlock it.
Usualy, to root it, you update your GS2 with an official samsung firmware, flash insecure kernel or CF Root kernel and then use the APK to unlock your phone.
I recommand before doing this, you find and download your original firmware in case of warranty support.
Kernel is the heart of the firmware/ROM
Firmware/ROM is the same.

Sorry to sound noobish but once and for all, rooting voids your warranty because the counter is raised? You can undo everything else (uninstall superuser/busybox and flash the stock kernel, you can even use a jig to reset the counter but did somebody with a rooted phone ever get to a point where he needed to make use of the warranty and if so what did samsung say and how much did that person undo (signs of rooting)?
I'm still unrooted because of the letters that Samsung sent to it's employies looking for signs of rooting when dealing with warranty claims. As good as the phone is and as much improvements rooting brings, is it really worth flushing 2 years of warranty down the drain?

Have you ever heard about phones refused in support by samsung cause of rooting ?
If you flash back your original firmware and reset your counter with a JIG usb, I am pretty shure they will accept the return.
But you sould always do as you feel it. If you are affraid of rooting your phone cause of the waranty, don't root it

You need to check if it is the same hardware : Exynos 1.2 Gh .... as others.
If not, firmwares provided (for now) in the section developpement won't fit your GS2.
In order to root, you will have to flash your phone with an official samsung firmware (without an opérator touch).
So you will have to wait someone to post the generic firmware from your country (intratech will certainly add it in his thread then).

Why does the firmware is country specific? Why would a UK firmware not work in canada for example? I am just curious.
How do I check if it use the same chipset or hardware version?
rooting SGS2 -PDA:KF3 / PHONE:KE7 / CSC:KF1 (DBT)
Hi ALL,
I just updated my SGS2 firmware last night via kies. As expected the previous rooted fw was lost.
I downloaded the GT-I9100_NEE_I9100XWKF3_I9100XXKE7_I9100OXXKF1.tar and I9100XWKF3_Kernel.tar from http://forum.xda-developers.com/showthread.php?t=1075278&page=69 and follow root guide.
Loading the firmware using ODIN was successful. When I run SuperOneClick v1.9.5, the process stop Running psneuter..... I also tried using the other exploit option but it also stop Running gingerbreak.....
Did anybody experienced the issue?
Please help..

Firmware is hardware and country specific.
You have custom data configurations with your country operator (for 3G and MMS). They are already configured in you firmware.
You have your langage dictionary too, keyboard configuration (AZERTY QWERTY QWERTZ ...)
Will you have NFC ? in France we don't have it and our firmware don't have drivers for NFC ...

Hi,
I just rooted my SGS2 and i have the same issues you did. The SuperOneClick hung at "Running psneuter"
I then followed the instructions from Chainfires thread here.
The CF-Root file i used was the KE4 version in the fourth post down: CF-Root-SGS2_ZS_OZS_KF4-v4.0-CWM4.zip - [Click for QR Code] (5.96 MB, 5066 views)
I then used the stock firmware for my provider to flash back.
Hope this helps.

Hi,
Why did you have to re-flash the stock firmware after applying CF-Root?
I thought CF-Root didn't affect the current firmware on your device.

If there is custom data configuration with the country operator, then doesn't that mean the 3G and MMS won't be correct for an unlocked SGSII from the UK in Canada? Or is this something that can be changed afterwards (I assume so)
Assuming that the hardware is the same for the upcoming Canadian version, these are the steps that I plan to take:
1. Purchase the phone with no contract (would be locked to Bell)
2. Use Odin to flash latest firmware for UK version. (Looks like it'll be XWKF3 - XEU (Generic UK+Europe) : http :// www .multiupload.com/ZZYM5ZAFA0 -- referenced from intratech's ROM's thread)
3. Follow Chainfire's rooting instructions and Flash CF-Root kernel for firmware (CF-Root-SGS2_XW_CLK_KF3-v4.0-CWM4.zip) (-- referenced from chainfire's CF-Root thread)
4. I should have a rooted phone by this stage. Next, Download and install Galaxy S2 Sim Unlock. (https :// market.android.com/details?id=eu.chainfire.sgs2simunlockcode)
And hopefully if all goes well, I'll have a rooted, unlocked SGS2 that works with Fido.
Would really appreciate it if anybody sees issues with my plan or can confirm that it should work.
Some questions:
* how can I confirm beforehand if the hardware will be compatible. Are we just concerned about the same cores used or does the hardware for radio come into play also?
Thanks,

The short answer: yes.
The long answer: yes it is.
I know that you came from an iphone where everything is done for you, but here there is a Search button - and it works really well. If you cannot find an answer or the answers are confusing/conflicting, then you post a question.
Note of warning: rooting your phone, flashing a non approved firmware or debranding your phone will invalidate your warranty. If you need to return for warranty, then you must return it to factory firmware condition (the ROMs for that can be found via this site) and the custom kernel counter must be reset with a jig - again the information for that can be found on this site.
Guys,
i've rooted my device and now i want to flash an Asia stock firmware (Hong Kong, Malaysia, Singapore) where do i download from ? i've found a link for Malaysia but the size of the file is only 26++ mb.. doesnt seem like a real stock firmware to me..
thanks
still no one can help after a day ????
^ I think there's a Hong Kong one in the ROM thread by intratech. Do a search, and I'm sure you'll find it.

[Q] How to ID a true sim free GS2?

looking at a near new GS2 here in the UK
How do I ID a true sim free GS2 vs just an unlocked one?
You probably can't if it's been correctly flashed to a generic ROM (which is what I presume you mean by unlocked), but if it hasn't, you can type *#1234# into the dialer and check the CSC.
whats the "CSC"?
CSC = country specific settings network settings etc .
Original Product code Original seller may give you a slight clue .
But network provider sell both locked and unlocked phones .
IMEI checking may give a slight clue as to country of origin

You may not get an update via Kies in all probability using a stock firmware can result in no matching product on Kies server .
You either wait for Kies update or start updating yourself via stock rom path .
The method is to pick stock rom to match your location .

[Q] Unlocked Samsung Galaxy S III

Hi guys, just a generic question. What does it mean when the phone is unlocked? I got an unlocked Galaxy S III I9300 and I'm using it on US T-Mobile. Curiously, the phone came with a lot of German T-Mobile bloatware. Are all I9300 not the same? Is it possible to make it completely carrier free? Please enlighten me
It means its not locked to a network .
Branded means its branded by a carrier/network.provider .
Flashing stock rom will remove the branding .

Thanks for the info. Is there a way to update to the stock rom officially through kies or something? And I'm just wondering, are there any carriers in Europe that use stock rom?

If you do it through KIES, it will keep all the branding, because it will update the ROM for the same CSC (operator-specific firmware) you have.
You need to first install, using Odin or MobileODIN, an unbranded firmware. All countries have branded and unbranded firmwares.
For instance, an UK unbranded ROM can be downloaded like this:
http://forum.xda-developers.com/showthread.php?p=28367295#post28367295
There are unbranded ROMs for all European countries. Use CheckFus to figure out what their CSC code is.
Thanks. So after i flash an unbranded firmware i can get the unbranded rom updates? And it won't wipe my phone right. Does samsung sell the I9300 with unbranded firmware and rom anywhere in Europe? Personally got mine on Amazon.

- It won't wipe your phone, UNLESS you tell it to.
- There aren't that many OTA updates anyway, so don't worry about it. Besides, when an update is released, you can install it on your phone using the Odin or MobileOdin methods long before it is available on the OTA. None of these require you to wipe your phone.
to use Odin you don't need root, but you do if you want to use mobileOdin.
I've flashed over 20 stock unbranded ROMs on my S III and I never did a data wipe on it, and yet it works flawlessly.
Using the top-right panel of CheckFus, you can download ANY CSC you want as long as it is for the GT-I9300. You don't have to keep it locked to a specific CSC. For Germany I believe the unbranded CSC is coded DBT (or something like that).
Hey, thanks for the info. The website for Checkfus Downloader isn't working. Do you have a link to it or can you post it here? From what I've read, CHANGING the CSC will wipe the phone right. Is there any reason for me to change the CSC to UK or something? I don't really care if the default language is German as long as I can change it to English. I just want to get rid of the bloatware and get an unbranded firmware/rom.
EDIT: Found the firmware on SamMobile. Thanks for the DBT tip.
http://www.sammobile.com/firmware/?page=8&view=6505
I just want to confirm flashing that won't wipe my phone? Because the CSC is different isn't it?
EDIT 2: Read your post again. So flashing the firmware won't actually change the CSC right. I just won't be able to keep the unbranded rom if I update via KIES?

-Ok, so. Basically I can flash any unbranded firmware I want (UK, German, etc...) regardless of the CSC.
-I just have to use Odin everytime I want to update.
-Also, will I lose the unlock?
-Will there be issues with the modem/baseband/CSC incompatibility or something.
P.S. I keep asking if Odin will wipe my phone because I used to own a Galaxy S 1, and Odin was basically the last resort to flash your phone back to stock, and it was always a wipe.
Thank you.
I have a galaxy s 3 which was given to me as a gift. It was on orange, but was unlocked for me so that I can use it on o2.
I have no idea how it was unlocked, but im unsure about upgrading the software through kies.
Can I still upgrade my software through kies to the latest jellybean? Because ive been waiting for the upgrade on my phone and it still hasnt come up. infact i dont have the option to check for updates either
what shall i do? I dont know if ill lose my data or block my phone by upgrading to jellybean via kies
help please
Your phone maybe unlocked but have the same carrier firmware. You need to flash via Odin a unbranded firmware, as if you do update by kies it may lock your phone again.

yes you can. but sometimes you may face modem problems like "you can't call or text people!" like in XXEMG4. i suggest you to backup efs and then flash any f/w you'd like to.
:good:
Just make sure that the firmware you are flashing is for the I9300 branch. Flashing other firmwares not suitable for the I9300 will well... brick the device.

My friend who brought be to this back-staging stuff told me this "Always take an nandroid backup first and do whatever you want".
But I may ask you why you wanted to install a firmware of other region? what is the benefits?:good:
