If I was you,Id root the phone,then backup efs,then make a nand backup....so you can get right back to where you are if you dont like it/or if theres a problem.
Or you can get one of them backup apps for saving the basic stuff you mentioned, since its "advisable" to factory reset/wipe your phone.
And I thought theres a Nordic JB released anyhow,is that no use to you?.You can check on Sammobile to see whats available.
Also have a quick look through the forum with regard to the problems people have when flashing JB etc,or roms from other countries without doing much research.
Thank you guys for the answer , so root is my answer .

No,not necessarily.Read my answer again as it says to "get one of them app backup apps".Ive told you what Id do,and told you what can happen to you when you try it(read all the problems in the q+a thread about no imei etc).
Maybe you can just backup up your apps/contacts etc,factory reset/wipe data then flash JB......and everything will be ok.Its up to you........
Hum...why do you wanba flash another ROM?
JB stock ROMs are all about the same.

well these are my questions, i'm looking for some answers i'm sure you can help me or erase these doubts i have.
Phone info:
Unbranded phone bought in USA and used in Argentina (sorry for my english, not really good)
Gingerbread 2.3.4
PDA: i9100UHKI2
PHONE: i9100UHKI1
CSC: i9100TPAKI2
i got my phone 1 day ago the first thing i did was a cf root kernel and my phone was root then i got speedmod kernel and everything ok (So only kernels customizations) but here is my doubt
1) Can i flash any kernel i want? I think i can, but.... haha
2) can i flash now any custom rom i want, for example villain, litening, etc
IF i can, will i have problems with mi 3g network. All the explanation with the csc is not clear on my head (or maybe i can put manually my apn settings, or flash a csc unbrandeed thas my stock rom has)
3) can i flash between any stock rom or this is not recommended
4)if i can flash any custom rom like villain, that custom rom is 2.3.5 and my phone is 2.3.4 is that a problem or not. maybe i need to flash an stock rom 2.3.5.
I have made efs backup, cwm backup, and my stock firmware is on stock firmwares thread so great
that's all thanks in advance guys
this forum helped me a lot.
PS: i have read al the noob guides and faq, and searched on the forum but truly i didn't find my answers and my english is not good enough haha so it's get complicated sometimes to understand clearly the idea.
im not expert but i can answer few of your question..
1. yes u can ( btw u didnt have to root ur phone at all.. since speedmod comes with preroot)
2. yes u can flash any rom u want but some roms isnt compatible with some kernels so u should read carefully which one is compatible
3. im not entirely sure but i think u cant... because different stock roms have different csc which is ur region data... i live in finland so i can only flash nordic roms.. but as i say before not entirely sure
4. about this i have no idea =/

Yup, you can do all of these. I installed cf-root on my own SGS2 aswell and went straight for custom ROM's (im still staying on the cf-root (stock with root) kernel. Didnt need a new one, but it doesnt matters you can do anything anyways).
As long as the rom/kernel you download is for the sgs2 (the clear one, not at&t or any other), everything will be perfectly fine.
As for the 3g problems, just try the rom out (or read feedback/ROM desctiption)

Oh and about question 4. Yes you can, its just like updating from 2.3.* to any other. I was on stock 2.3.3 and jumped straight to the Revolution ROM which is based on 2.3.5

I never had problems with csc. Never even touched it. Just flash the ROM's and thats it
And about connection, you should simply get the Modem that is suitable for you after flashing the ROM, but thats not a problem

Hi,
I just got my Android and happened to Root it with a firmware containing CWM because I really had no clue as to what it was. Now I would want to be able to remove this icon CWM from my phone. I have tried flashing the kernel to no avail. Please help me with a step by step procedure to remove it since I'm absolutely new to Androids. My S2 runs gingerbread 2.3.6. I did check the web but am so confused with all the options provided.
Thanks in advance.

It is strongly recommended to back up stock ROM before u give try to Custom ROM.
*#1234# - Check your Firmware version before u do Rooting and make a note some where
You can use those information to download your STOCK ROM from many website (google them)

Since you are rooted, use any file explorer with root access and delete the cwm manager.apk.
Second option is use root un-installer and uninstall the cwm manager

in some Firmwares CWM is included in system applications, so cant simply uninstall it, you can use Titanium backup application to uninstall system apps,
But before uninstalling better you learn more about Rooting and the functions of this app and other root apps. This is a very usefull app in the rooted and Clockwork mod installed devices, for rebooting into recovery easily, kernel flashing, backing up of the Rom ect..
you can have informations from below sticky thread as well as from my signature links.

why do you want to remove it though? Its one of the most useable apps for a rooted phone

I installed CWM to test some custom ROMs on my device. What if for some i reason i have to take my mobile to service center.
Will they charge me (even if my device is under warranty) because i have installed CWM?
Do I really need to remove CWM? If yes, how??

Yes you will need to remove root so flash Sam firmware with mobile Odin and don't root. Now back to stock. :thumbup:
Or send it in and report bk

Thanks for replying andrewwright!! (you too "theunderling"!!:angel
I haven't actually installed CWM yet and came here to clear my this doubt.
Why Sam Firmware (if Sam = Samsung) while my device is XOLO q800? Can I take a backup of my my stock firmware in some way because XOLO is not a popular brand and I won't get much support(stock firmware) over internet.
Also, I read somewhere that particular firmware corrosponds to a particular chipset(mine is MT6589), is it true??
I would really appreciate if you can provide a link for reference where I can read further or otherwise some people will keep yelling here "noob......noob"

Hello guys....
I am very thankful to the xda forum and all the members who helped me to get through a serious problem..
Recently I installed 4.3 Leaked version on my GT-I9300 and the ROM proved to be worst ROM of life. So I decided to go back to 4.1.2.
I installed the Stock ROM via Odin but I confronted a serious issue, when I was finished the installation I found that there was no network at all... Samsung's official told me that it is impossible to reverse the Android version...
I had no clue what to do. I flashed many ROMs but no solution at all. My IMIE was also kinda jumbled..
Many guys said it is EFS issue... But it is not EFS issue...
It is all because of different Modem issue.. all you need to do is just install a clean Stock ROM from http://www.sammobile.com/firmwares/2/ and Install the patched modem... you are done..
So here is the solution:
1. Download your desired Stock ROM for your Country from Sammobile...
Link http://www.sammobile.com/firmwares/2/
2. Install the ROM via Odin
3. Root it and Install your favorite recovery.
4. Install the Patched MG4 Modem Zip in Recovery Mode. Link https://www.dropbox.com/s/geispctijpxqjms/Patched_Modem_I9300XXEMG4.zip
You are done....
This problem is all about MODEM version, so I don't think if EFS tricks are involved here.....
Finally credits go to all the XDA Members who put their heart and soul to present all the required guidance for me to be able to downgrade to lower Android Version.. I have only compiled the whole stuff into a single thread....
Thanks,,,

I can confirm that this method works. XEMB5 (4.1.2 stock rom) on top of the crappy 4.3 update, rooted it and then installed CWM. flashed the patch modem from the link he gave and the XEMB5 rom is working with network running again. but it seems like the battery is awful, 95% in just 10 minutes? lost 5 percent for that short amount of time -_-
then again, thanks for this!

My problem is little different. I can flash any ROM via Odin[DO NOT FORGET TO CHARGE YOUR MOBILE ABOVE 80% battery level!]:
1. Goto recovery by pressing "vo upl+home+power" release when you Samsung's bootloader.
2. Do factory reset/wipe everything.
3. Remove battery for 10secs. Then put it back.
4. Now press "vol down+home+power" to bring it into download mode. Then follow odin flashing procedure. It will work for any Samsung rom. No need to intall any custum roms.
Now going to my problems:
A. My s3 shuts down when it's idle.
B. Bluetooth button does not work. It tries to go to ON position but goes back OFF after 2/3 sec.
After downgrading from earlier 4.3 [SWC] I have even upgraded it with latest 4.1.2 xxemh4 but no luck!
Every thing works network, wi-fi etc. except above two problems!
Help me please!!
I FOUND SOMETHING, WHEN I DO *#1234* IT SAYS CSC: UNKNOWN though my network is ok and wi-fi works fine. Lemme try patching CSC as featherknox suggested!
@featherknox, But your patched modem can not be flashed in recovery[stock] mode as it says "Signature verification failed". HELP ME WHAT I SHOULD DO?

Ok guys here's the deal, last year I rooted my friend's s3 (international, india, i9300) because there was no available update to android, so I flashed purelook HD 8.0 (android version 4.1.2), now he is saying that his phone has become very slow so he wants to go back to stock
so I downloaded "INU-I9300XWUGML4-20140107141249.zip" but after downloading this I saw that it is for android 4.3 (new official update).
So my question is should I directly flash this in ODIN (android 4.3) or I should download older official update before flashing new update?
If it's a full, multi part stock rom then it wouldn't be a zip. Odin can't flash zips.
Suggest you read the basics in general forum, sticky threads, before you do anything else.

yeah I know odin doesn't flash zip's, I quoted the file name just for reference as there were two firmwares updates available for india, one INS another INU on doing some searches I came to know that they are locked and unlocked updates, kinda same, you can download any one.
is there any number I should match before downloading...we do not have contract phones in india, just retail so I was confused therefore I downloaded the unlocked one
back to the point, I know that I have to extract it first, there is a file inside it, named "I9300XWUGML4_I9300ODDGML4_I9300DDUGMK1_HOME.tar.md5"
so maybe now you can help me out, whether should I flash it or download an earlier version and flash it prior to flashing this one...
So my question is should I directly flash this in ODIN (android 4.3) or I should download older official update before flashing new update?
Its your choice but as said read and understand the basics first .

Well I know how to flash roms/firmwares via ODIN, I know I have to check my counter too if it is not zero than I will have to reset it
so is there anything else?
I'm just asking this because I don't know much about s3 but I had note and I remember it had some issues regarding upgrading to a ice-cream sandwich version, something related to 'safe kernel' many other things...
and even I tried searching for basics, I didn't find anything else other than this and if there is something I am still missing then please kindly link me to it or just answer the question, IS IT SAFE or not?

My friend bought GS3 months ago in Arabic country with ICS 4.0.4 installed. When I saw the box, I found that the GS3 is a grey market product. It has Region Lock label written in Russian language on the box and the ROM is pre-rooted CWM Custom ROM
Now, Kies dose not upgrade this version and he wishes to have Arabic stock ROM 4.3 if possible. What are the safest steps to do?
- If I download and flash Arabic stock ROM, will I loose modem connectivity?
- Do I need to backup and restore EFS data if I flash stock ROM?
- Do I need root to restore EFS data/modem driver after flashing STOCK ROM?
- Should I flash custom ROM instead of Stock ROM?
I want a safe way, I don't wish to cause network/EFS loss to the device?
I read a lot but came to no conclusion.. please help

Kies shld have an emergency firmware feature. Try using it.
1. U will not. Just dun downgrade
2. If u aren't gg back to 4.1.2, dun bother. But recommended.
3. Yes.
4. Ur choice. If u wan bugless rom, go for stock rom. Many also say stock is one of the best.

Depends on the phone history on what will happen on upgrade to 4.3, sim lock may return or imei lost due to patched efs folder. No way to know until you get flash, so backup efs now.
4.1.2 EMG4 is when efs format changed, anything before this shouldn't cause too many issues.

That's what I am worried about. To loose IMEI or get the region lock back. The phone model is GT-I9300RWDEUR. Can I find stock rom for it with no region lock?
so confusing !!

I am worried I will get back the region lock crap if I do firmware recovery!!
The model is GT-I9300RWDEUR European SIM model
The ICS 4.0.0 is causing to many problems and device hangs all the time
Actually it is from Greece. I was confused with the language (Ελβετία= Swiss)

So if I upgrade to 4.1.2 before EMG4 , I won't have EFS/IMEI problem?
All I have to do to flash midle east ROM and then to find the Modem driver and install it through odin?

Modem may be a CWM zip not a tar .

What is the difference? Odin only flashes tar?
I need to find modem driver in tar format first?
Odin flashes tar
CWM and other custom recovery flashes zips .
Suggest you read the basic faqs and guides first .
