Thanks for your response, first my region is ireland, and I did check Sammobile, the firmware link on the website seem to be for registered members only. Tried registering several times but for some strange reason it keeps failing. I would like to know if I could do same download through Samsung kiers and the difference between a stock Rom and a stock firmware? Thanks

I'm on the 3IE network, and running the jellybean 4.1.1, I've it unlocked all these before I rooted my device.

Both 4.1.2 and 4.1.1 (and everything before that) are available on SamMobile for your phone.
I still can't post links so you'll have to de-butcher this, but that'll take you to a listing of firmwares for your country/carrier. Choose the one you want!

Sorry chucky17ng, I didn't read your post properly. For your purposes there is no practical difference between "firmware" and "ROM". And no, if you have rooted then Kies will bomb out saying your device has been modified.
Your best bet is to grab the firmware once your registration goes through (or source it somewhere else), drop the file onto your phone, then flash it with mobile Odin.
There are other ways, but I know that one works.

[SOLVED] Cannot find correct stock firmware

Hi there
First of all, i have checked out intratech's thread but the links referring to the firmware are not working. I have also checked sammobile, and i found a firmware that supposedly was for my phone, but Kies begs to differ
Anyway, the phone i have is a GT-9100LKANEE, and it was shipped with
android: 2.3.5
baseband: I9100XXKI4
Build: GINGERBREAD.XWKI8
So i thought i struck luck at sammobile when i found this: I9100XWKI8_I9100OXXKI2_NEE.zip.html
It flashed allright and i thought i was out of the woods, but when i went through the startup wizard the language was danish (i am norwegian), and now Kies wont even bother looking for updates for my phone. It just says "this device's version cannot be updated"
So much for the "stock" experience
Can anyone point me in the right direction?

You can use Check Fus Downloader to check and download stock ROMs directly from Samsung servers.

I downloaded the right one, but it is the same as the one i flashed from sammobile. But for some reason Kies does not want to have anything to do with updating my device. I mean, it is fully updated now though, but whenever ICS comes along through kies, it wont let me update.
This was all easier when all i had was the HTC Hero
Unfortunately, that seems to be happening a lot to people who have gone back to stock firmware. Kies should work so far as receiving updates go, but for whatever reason they don't. It may be a case of having not downloaded the correct firmware in Checkfus. It may be some kind of country mismatch which is causing Kies not to allow you access to updates. Or it could also be that Kies has no updates available now.
Having not experienced the problem (and having not ever used Kies/not wanting to ever use Kies for anything/and not really being interested in ICS), I can't say why this is happening for sure.
Whatever the reason for the problem, when ICS is released, you'll be able to download this with Checkfus as well (Checkfus enables you to download any firmware updates available via Kies).

I'm in Norway too, and as far as I know KI8 is the most recent official stock firmware. I'm on Netcom, who's your operator?
Try an older stock firmware - KE7 for example, and see what Kies updates to. Back up first though.
Lykke til.

I am on Teliasonera (Tele 2)
I'll try your suggestion!
Takk.
So i think i have found out why Kies wont update my phone. It seems the product code on my phone has been changed somewhere along the flashing spree i've been on.
My phone is originally a GT-I9100LKANEE, but now it is GT-I9100LKAXEU. So what now? i downloaded the firmware for LKANEE on checkfus but it still comes out LKAXEU.
Do i have to change it manually? Like explained here: http://goangeek.wordpress.com/2011/10/11/how-to-change-sgs2-product-code/
And do i have to flash something again?
I am completely lost at the moment.
And i am threading around carefully because i dont want to brick my phone in the process.

[Q] Rollback GS2 to GB 2.3.4 from ICS 4.0.3

I have a new unbranded Samsung Galaxy S2 from Carphone Warehouse on Orange.
Baseband: I9100XXLPS
Kernel: 3.0.15-I9100XWLP7
Build No: IML74K.XWLP7
It came with Gingerbread 2.3.4 and I loved it. Having plugged it into Kies for the first time and accepted the software update it is now on ICS 4.0.3. I like absolutely nothing about this version and have tried to roll back to GB 2.3.4 using Odin and the link to my version of CPW firmware from skywanker.net. I was under the impression because the phone came with 2.3.4, the flash would roll back to this but it hasn’t. It is still on 4.0.3. and having now found my way to the new list of firmware on Android.firmwares.net I can see that it lists this download as 4.0.3.
Can someone please tell me how I can find a GB 2.3.4 suitable for my CPW XXLPS phone so I can roll back to the stock version it came with?
It is not rooted. I don’t want to root it I just want it as it was out the box and still under warranty!
Please help. I have spent literally days and days trying to find this answer after having plucked up the courage to flash my phone with Odin and I am so disappointed that all I’ve done it put 4.0.3 back on it!
I have spoken to CPW, Orange, Samsung and CPWs Geek Squad and come up blank!
Thank you ;o)
Tried samfirmware.com ?
Thanks for such a quick reply B3311. I've looked up the firmware for my PDA at samfirmware and it is also showing as ICS 4.0.3. This is what I find so confusing. My phone shipped with GB 2.3.4 so why can't I find that anywhere to download and roll back?! Any other suggestions?
http://www.hotfile.com/dl/150009521/71118c0/I9100XWKI4_I9100XEUKH2_XEU.zip.html
you could try this one. official 2.3.4 filed under europe, united kingdom/ireland.
or this one europe, open europe official 2.3.4 firmware
http://hotfile.com/dl/145783246/da10e07/I9100XXKH1.zip.html
Search again at sammobile, you will find the 2.3.4, if you can't search, no one can help.
Hint: Look in Europe
Don't forget to wipe
Before and after flashing.
Look at 2.3.6 aswell if you want.
Sent from my GT-I9100
Will these downloads be compatible with my phone and if I load them would they void the warranty? If anything goes wrong could I just load the 4.0.3 again via Odin? Sorry for so many questions but I have no experience of this sort of thing. I don't even download apps to use - I just like the standard stock function of the phone - or rather I did before ICS!
yeah i understand what you mean ics is pritty buggy and not as good as gb yeah they should work just fine like anything to do with flashing tho its not 100% safe. just download and flash away but take your time
Flashing stock, unrooted firmware will not void your warranty.
May be worth knowing that 2.3.4 is an older version of GB. 2.3.5 and 2.3.6 are newer, and "better" (IMO).
I'm on 2.3.6, and have no intention of moving (I will not call it "upgrading") to ICS until I get the SGS3 next month.

it depends you flash the same FW, if your dealer finds the firmware version on the phone is not the same when it was supplied , they may deney waranty...so its upto you to find the exact version and flash...
wrong....if some thing went really wrong and gone to unrecoverable stage you cant load 4.0.3 back
Normally there is nothing going wrong if you have followed the steps correctly and carefully....

All I've been doing for the last 7 days is searching, searching, searching. I can assure you I have tried to sort this problem out before posting here so please don't suggest that I can't search! Just because my level of expertise in all this is zero - doesn't mean I'm not tyring to learn and help myself!
I am not one to customise the phone so I am very wary of what I am doing to it. I am trying to ensure that I don't make matters worse for myself. I had searched samfirmware according to the criteria of my phone that they requested and it returned only the 4.0.3 option.
I have now found the list for older firmware and can see that there are some 2.3.X under Europe, but my next question is - how safe is this to use with my phone. I was under the impression from the XDA guidelines for flashing with Odin that you should only use firmware that is compatible with your own PDA, Phone and CSC. Will it void the warranty if I put something for Europe on there or cause issues with the function of the phone?
Also - I'm afriad I don't know what you mean by "wipe" the phone. Do you mean do a factory reset?
Go here and find GB Version you wanted.
http://samsung-updates.com/gt-i9100-galaxy-sii/
Thanks for everyone's input so quickly!
I've had a good look at the list on Samfirmware and I'm guessing my best option is to try the one for GB 2.3.6 for UK (Orange). I will give it a go.... watch this space!

That link provides a very comprehensive list of firmware for my version of phone, but still not the GB 2.3.4 it was shipped with! This is exactly why I'm so confused; I just find it so odd that there is no way to find the orignal firmware for this PDA. Does anyone know if this a common thing with Samsung phones and firmware?

I keep kicking myself for allowing the update to run! I'm just not up to speed with smartphone tech I'm afraid, but I never allow major updates onto my computer until they've been around a while and all the bugs fixed which is why I am so angry with myself for not being clued up on ICS!
If I'd known about the ICS changes, I'd have stuck with GB for the cute android emoticons in SMS alone ICS has really mucked up my phone and the way I use it. I have no idea what possessed them to release firmware that has removed such useful basic functionality from so many everyday things. And as for the signal and battery problems - that's a rant for other existing threads!!!
I had an intereseting convesation with Samsung Tech though - it seems they are very aware just how buggy ICS is and the issues it's causing as they told me I'd have to send my phone back for a hardware repair if the battery life didn't improve. If this rollback doesn't work I can only hope they release a fix very quickly.
The GB 2.3.6 is slowly downloading so hopefully I’ll be able to give it a go later today. Doesn’t help that I live in the middle of the Fens in Huntingdonshire so am surrounded by beautiful country but only 2mb broadband. AGH!!! Some days I really miss cable
Disaster! Got GB 2.3.6 OK - but it's all "orangified"! Should have realised that but thought because I'm on orange that would be the right one. So now I'm downloading the 2.3.4 for UK / Ireland as orignally suggested by jonnyhall1bmx1. I'm hoping this one will be totally open and not linked to any carrier.
See what happens when I let my brain get involved!!!

since your phone is already unbranded, no need to be on a carrier ROM, search for XWLA2 or XWLA4 which is the latest versions of 2.3.6, may be released for some country name (italy ) doesnt matter...
Good for you that you search, I don't intend to make fun or insult, just that search function works and it's better to get some knowledge before hand instead of relying 100 percent on others.
Now, yes flashing using Odin is safe, as you have experienced now. La2 is the best I found and I always go back to it when required.
Yes wipe means to clean data cache.
Wiping do erase your stored files on internal storage. So remember this.
Always good to do this after and before every flash.

(a newbie)
Well I'm absolutely delighted to report that the last firmware flash has done the trick. I'm back onto GB 2.3.4 and all the functionality that I liked is back and the battery and signal strength already improved. What a huge relief! Thanks to everyone who posted here to help me. This is a great forum and it has encouraged me to be more confident with my phone and its functionality in the future.
I sincerely hope this thread will help others out there to rollback from ICS if they have the same issues I did. Ciao for now folks.
Hi,
I would like to thanks to all contributors to this thread.
I also want to rollback to 2.3.6 from 4.0.3 and I own an orange branded galaxy s2.
I've found the necessary firmware from sites posted here (I9100BVKL1_I9100OROKL1_I9100BVKL1_HOME.tar.md5).
Also, I've understood that I need only Odin for this operation.
I would like to have just a confirmation from you guys, if the method mentioned here works in the same way on branded galaxies (orange specifically).
Thank you,

Unlocking and unbranding a Sgs3 on the 3 network UK

Is this easy enough to do. Got the chance of buying one at £400 but would need to unlock it and preferably have it unbranded.
Is the unlocking part something I could do myself or would I need to take it to a vendor and how much would it cost?
Thanks.
The 3 phones are unlocked already
It costs £10 on ebay for an unlock code
Easy enough to un brand by flashing a stock firmware .
But i would wait until i had a copy of my original firmware first in case of claiming on 3 warranty .

Mine is on Three and unlocked/unbranded (although I did get it via Carphone Warehouse) so your mileage may vary.
R.
I had a 3 UK phone, I got it since the launch, as I had it pre-ordered, and it arrived locked, however I used the Voodoo SGS III Unlock Tool and it worked brilliantly, it is free to download and it unlocks it almost instantly, however ROOT is required.
For the information of anyone reading this thread, in branding is as simple as flashing a generic official rom from your country via Odin, takes 5 minutes.
Unlocking is done via the methods shown here in the forum and is free, again, takes 5 to 10 minutes.
To undo the changes, flash back to the carrier ROM you had originally, and I wouldn't worry about undoing the unlock.

Could anybody with a more in-depth knowledge care to offer a bit more info on this?
I currently have an O2 branded S3.
I have rooted this (when I first got it) and that went fine (Odin, I think was the method I used).
If I wanted to flash a basic unbranded image on this, would I use the very first post from this thread, labelled "I9300XXBLFB"
http://forum.xda-developers.com/showthread.php?t=1646610 (If not, could somebody point me towards the correct file please?)
Then, If I ever needed to put an O2 image back onto it, (maybe for warranty purposes) could somebody point out where I would find the O2 branded one, as I can only see an Orange branded one in the following post?
Also, is there actually much risk involved in the flashing, or would I be really unlucky for anything to go wrong?
(P.S. I've seen the thread about how to change the handset back to make it seem that it's never been flashed/modified, so I realise I'd need to do more than just flash the O2 image back onto it. Hopefully, I'd never need to anyway).

1st of all dial *#1234# into the dialer this will give you the current firmware version(im assuming your still on o2 firmware and havent changed it yet) then go to here
http://www.sammobile.com/firmware/?page=3&t=1&o=1&m=GT-I9300&r=1#regiona
this is s3 firmware version for europe and find the firmware that matches the 02 version your on. This is your fallback incase you need to warranty repair the phone or you maybe have a flash problem with unbranded at least you have the o2 to fallback on.
Ill assume its more than likely this one
http://www.sammobile.com/firmware/?page=8&view=4650
and heres the dl link for it
http://www.hotfile.com/dl/157417303/f25aa83/I9300XXALE8_I9300O2UALE5_O2U.zip.html
Then as youve already mentioned flash the LFB version, here ya go dl link
http://www.hotfile.com/dl/162402398/abc9bdb/I9300XXBLFB_I9300OXABLFB_BTU.zip.html
Now if you want any other versions of official firmware you will need to join sammobile to be able to dl them
Thanks very much for the reply.
A couple of issues having taken a look at those links.
The first link doesn't seem to have my firmware listed - some are close, but none the same.
Mine shows: AP: I9300XXALEF, CP: I9300BWLE6, CSC: I9300O2UIALE7
Would an alternative work if I ever needed to flash back? (maybe the one you've linked in the 2nd link?
And, finally, to confirm - the last link - "LFB" (not sure what that means) - is that the unbranded rom that I'd be looking for?
Many thanks for the advice.

Have your tried updating through kies 1st? As far as im aware you will still get o2 updates through it. I noticed my phone out the box(unbranded) didnt have firmware matching this list either but after a kies update I was on firmware more well known for the region and was on the list.
Yes the LFB is the latest unbranded firmware.
edit:- doing a bit of research it seems o2 branded phones are running the LE8/LE5/LE5 software so i think your missing an official update.
I've not really used Kies as yet. I'm running Mountain Lion on my iMac, & Kies won't install on that.
I can always use my lappy at work tomorrow to look into it.
If I was going to change to the unbranded firmware, I assume there's not really any point in using Kies to update the official O2 version on here at the moment?

No point jumping forward then realising your not sure what o2 firmware u need in case anything goes awry

Kies is, as you say available for Mac, but won't yet run on Mountain Lion. I'm assuming they'll update it soon.
You were right, Kies did update my O2 branded handset to the latest FW, which does show on SamMobile's site.
Phones from the three network are locked, carphone warehouse phones are unlocked as they're from the suplier.
Theres a tool called voodoo i beleive it's used for unlocking the sim on samsung phones, you should give that a whirl.
It's available on the market.

HELP Updating GT-i9300

Hey guys, I am new to the S3 and Andriod as I used to be an iPhone user before. I bought a GT-i9300 from Hong Kong and brought it back to Canada and cant seem to get any software updates. I am currently sitting at build number I9300ZSALG3, just wondering if anyone could help me out doing an OTA update or via Kies or if this is the latest version. My baseband version is I9300XXLG3

Your firmware is from Taiwan..and for it the latest version is what you are currently using..however you dont need to wait for updates you can download firmware for United Kingdom the latest is I9300XXBLG8..you can download it from here..
http://samsung-updates.com/get/58/Samsung_Firmware_GT-I9300_BTU_I9300XXBLG8_Android_4_0_4.html
then flash it via odin...search these threads for the method to do so..
Hi man, Unlike iphone,offical rom is always the worst one.It usually uses more memory and have bad battery management.You can try another rom such as mike's.
Sent from my lovely GT-I9300,by the way,I'm a Chinese!Glad to communicate with you

Thank you! I am not too familiar with flashing with Android again because it is something new and if anything were to happen I wouldn't know how to fix it since I have been an iPhone user. Is flashing firmware any different from jailbreaking the iPhone? - in terms of being safer. Also, how can I be 100% sure that the UK version will work on my phone as well as keep my unlock.

Hey, again as I said to the previous member, I am not too familiar with flashing nor am I keen on doing it just because I am new to the Android community

Flashing the firmware is 100% safe if you follow the steps..it does not root your phone so it is not jailbreaking...so you will also not loose your warranty...
the firmwares are almost the same for every region, samsung being an a***le released different firmwares for different regions with different CSC....
but i am quite sure it will work on you region as you are already using Taiwan firmware in Canada...in any case download the Taiwan specific firmware also..so if anything goes wrong you can revert back...
by the way I am in India using BTU firmware..
Me too...
Along the same lines, I have an I-9300 sgs3 with South Africa firmware (XFE), i9300xxale9, but I'm using it in the United States, on AT&T, and am not able to receive updates thru either Kies or Update menu. I will NOT be traveling outside the US anytime soon. What should I load that would let me receive updates here in the States OTA?

SGS2 Update Failed. HELP PLEASE

Hello, lovly xda-Members and Supporters,
I'll start so my mother and I use the same smartphone - Samsung Galaxy SII GT-I9100 ...
When she came back home from work and she told me that there is an update for this, I was blown away,
I was looking through the manual setting on the phone for an update, but it said: No update available ...
So, all well and good, then I tried to update via Samsung Kies, Samsung Kies now says to me: Software update via Samsung Kies is not supported by your device ...
I Did something really silly the other day as i flashed a rom to my Galaxy S2 i9100 and i stupidly forgot to back up my stock firmware.
Is there a possibility to get my old firmware again?
I live in Germany.
& I'd love to have this update on my phone.
Each answer is helpful and I thank you once in advance!

You most definitely can return to stock, but if you didn't back up whatever data you had before flashing the new ROM, then they're gone (assuming you wiped before flashing). You'll find all the firmwares you want here:
http://www.sammobile.com/
I'm assuming that you had ICS before flashing the custom ROM, because you said you didn't receive an update, so you can most definitely do that OR, you can manually flash the update you didn't receive yet, which is 4.1.2 JB Anyway, all firmwares are there
Viel Glück

it was for 4.1.2 JB ? my phone is actually 4.0.4, it was allways 4.0.4, so it isn't for my phone anyway ? where can i find stock everything for my phone ? on Sammobile it shows me Taiwan 4.1.2 ...
PS ; Your German ?
In case you still need ICS, Then I'd suggest you google for that. Just search for samsung galaxy S2 4.0.4 firmware. you should find it. It's also helpful if you add your service providor (O2, T-Mobile or any other) just to make sure the phone will work with that network. It's just safer that way
I don't know if we're allowed to post links to outside sources here, but it's enough to say that many German android forums have what you want you just need to search really well
Not German, but I live in Germany :silly:
