I've got a galaxy s2 from 02 and it is branded and running o2's flavour of software.
I've attached 2 screenshots to show the version I have.
Is it worth it for me to debrand, what would I realistically gain? I've looked through the forums and it seems there is newer generic firmware available. But there also seems to be mixed opinion as to weather it's worth upgrading. From what I can see I have 2.3.3 KF3 if that helps
It also appears that by flashing generic stock firmware via odin I will still be able to use kies so any future releases will download through kies using the firmware update feature?
Answers as always appreciated.
IF you download, from here, the latest stock Samsung ROM, then you will be able to fool KIES into thinking that your phone is no longer an O2 SGSII but a unbranded one. Thus you will be able to get the next available update of the official stock ROM when it is released via KIES.
The most important feature is an improvement in battery life.
If you stick with the branded ROM, then you have to wait a few months for the stock update to be customised by the operator and released.
This is the most important: if you flash an unbranded ROM, then you have invalidated your phone's warranty. You can simply reflash the O2 branded ROM, again available on here, this will put you phone back in warranty.
ok I see is there a link to the post that has the most recent fw? I will ofc check the dev forum stickies Many thanks for the swift reply and advice.
Without a doubt, so many good custom roms available and more newer stock firmwares. You can undo everything so no need to worry about putting it back to stock o2
cheers
Yeah I think I'll flash to generic stock rom then take in the updates from sammy, I'm blown away with this phone as it is running stock roms.
Will wait for ICS to be available on a un-official rom before I debate custom roms,
As soon as I got my sgs2 from O2, I debranded it straight away
Wow what a difference my phone is marginally faster one booted on 2.3.4 bootup is way quicker internet also seems faster.
Unlike X10i flashing new fw didn't basically factory reset the phone everything was as i left it bar the fw.
Had slight issue where it seemed to hang at the last big galaxy s screen for a minute or 2 when first booted but all phones seem to do this when flashed.
One question - my market hasn't changed os there a new one and should it automatically update?

I bought the phone in January sim free, for full price from my local mobile phone store. It is running stock android 2.3.4 (build number: GINGERBREAD.XWKI4). Its been in the online news a lot that ICS would be available by the end of Q1 but still, i am unable to update. I get a message saying my firmware is the latest available.
I live in New Zealand and as far as i understand you (USA) have ICS but what about for me? I'm assuming my phone is the international version so i thought i would have the update by now.
So does anyone know the full story?
Thanks
ICS hasn't been released by any of the NZ telcos yet (I checked with Checkfus). You can pretty much run any ICS stock (or custom for that matter) rom you want. Lots of Odin (mainly stock roms) & CWM flashable (mainly custom) roms on here (search the development sections).
One thing to bear in mind if you do flash a stock ICS rom from another region tho, you may have problems getting updates via Kies in future. If that happens, you'd need to flash a stock rom for your region in order to get Kies updates again. Or you could do what the majority of people on here do, bypass Kies completely (horrible excuse for software) & flash all your roms manually.
As long as you've got an I9100 or I9100T you can flash any firmware for these phones.
Fellow Kiwi here mate, just flash any ics rom thru odin. I've had no issues whatsoever, the latest Lp7 rom with speedmod kernel is the best I've had. You wont regret it.
I'm with telecom, they wont update anything quickly at all.
Hope this helps your decision
I live in China and I bought a GT-I9300 yesterday.
I noticed the phone was out of date when I got home so I started the update process, the first update went smoothly the phone rebooted and I checked if there was any other updates and there was one. The update downloaded successfully and rebooted to install and got to 31% and failed out and rebooted the phone.
At first I thought it was because the phone was partially set up to show that it wasn't a fake phone, so I did a factory reset and started the whole process over, and the same thing the update fails out at 31%.
The phone suggested I use Kies, but Kies says my phone's current firmware version is not supported via kies.
So I took to the internet to try to manually update, I spent the better part of yesterday and today trying to figure out everything about this phone but I just can't seem to get a 100% conclusion on anything so I don't want to try flashing anything and possibly messing up my phone. There just seems to be 50 different models that all have different roms and I don't want to flash the wrong one.
Info from Kies: Current firmware version: PDA:LF1 / PHONE: LEF / CSC: LF1 (XXX)
From my phone:
Model Number: GT-I9300
Android Version: 4.0.4
Baseband Version: I9300XXLEF
Build Number: IMM76D.I9300ZSALF1
Part of the problem was the guy was selling both the Western Europe model and the Hong Kong model, I was told I was getting the Hong Kong but he may have given me the Western Europe model by mistake.
From what I have read XX means means Western Europe model but another website said ZS was Hong Kong? I don't know if I go off the Baseband version or the build number.
Then I thought I will just root the device, slap CMW on it do a backup and then slap CM10.1 on it and call it a day. But following this rooting guide I need to know which version of the phone I have first.
http://forum.xda-developers.com/showthread.php?t=1671969
Also CM10.1 only has 1 I9300 (International) build is that a universal I9300 ROM that is safe to use on my phone?
Long post but the help is appreciated!
So I think I figured out why this isn't updating, and I think it might be rooted as I see the SuperSU app installed. I don't really care if my device is rooted or not. SuperSU has a "Clean up feature" but it isn't uninstalling and removing root.

I'd suggest you return the phone to the guy and ask for a completely clean no root version of the phone. But if that's too much of a hassle right now you can just flash stock firmware using Odin.

Right I would just flash to stock with Odin, but that was part of my question. Which stock rom do I use? Or does it even matter and any ROM will work, I think I have the Hong Kong model but I am not completely sure and I don't want to risk bricking the phone with the wrong ROM.
Your phone does seem to be an International version which means any ROM except the China ROMs will work.
The reason Kies will not update the phone is because the CSC is XXX which is pretty strange but seeing how the phone came rooted someone has been playing.
Do you want to use the phone in HK or CN? and do you need Chinese input?

I use it in China, I rarely to HK. I don't need the Chinese language on the phone although it would be nice as I am trying to learn Chinese, but I could live without it.
Thanks for your help! Much appreciated.
I a going to flash this ROM today and see what happens!
United Kingdom 2012 December 4.1.2 I9300XXELL4 I9300OXAELL4
I'm in a similar situation,
Baseband: I9300XXLFB
Build Number: IMM76D.I9300XXBLFB
Let us know how you go with the update. Thanks

The ROM you are going to flash should be ok, if you ever need Chinese input then flash any ZS or you can just install Google pinyin IME.
BTW If flashing the ROM you was going to, does work ok, then your better off having the International version than the Chinese version anyway, since you are not stuck to waiting for Chinese ROMs or installing hybrid ROMs.
Yeah I am having trouble finding a download that will work here in China and my VPN connection is down so it will be sometime before I can even download this ROM. samfiles or samfirmware can't remember the website, is blocked in China, hotfile.com is blocked which seem to be about the only 2 websites that host all the firmware downloads.
EDIT: Speak of the devil, my VPN service just released an update for their connection app, I am downloading the ROM now. Should be able to report back in around an hour and let you all know.
EDIT: Spoke to soon, VPN issues again.
would someone be willing to download I9300XXELL4_I9300OXAELL4_BTU.zip for me and throw it up on a dropbox account or some other website besides hotfile.com I am having trouble downloading this file from China.

Yay, I was able to get my VPN connection to stay on long enough to download the firmware and I was able to successfully apply 4.1.2 Jelly Bean to my phone!
Thanks for all your help!
Kies now reads: PDA:LL4 / Phone: LL4 / CSC: LL4
Hi Guys
I have a SGSII, which I got in Hong Kong a couple of years ago. It came pre-installed with Stock Samsung Firmware ICS 4.0.3. I currently living in the UK and was wondering if I did a Firmware update using Kites, would it install you UK version of the firmware instead of the HK version?
If it's got the HK firmware/CSC on it, it will update to the latest for that region; where you are now is irrelevant, it reads the CSC info off the phone to determine what firmware to upgrade to, assuming there is a later firmware for that region.
But it's a moot point. Why would you use Kies for anything ? Flash whatever stock rom for whatever region you want with Odin.

Hi Everyone,
Can anyone help me with process for flashing UK version firmware of XQ-BC52 on Taiwan version of XQ-BC72. I need to know which firmware files such as ".ta" or any other files to be removed from firmware folder before flashing. The UK or US customization versions supports volte and Wifi calling in my country.
Currently the Taiwan firmware version is at 61.0.A.23.20 (android 11) and UK firmware version is at 61.1.A.2.211 (android 12)
Can I just flash the .oem files of UK firmware to TW firmware?. But, since device firmware versions are different, flashing may fail and corrupt the device. Can you confirm if this is safe to flash?.
Request your help!

I think yes but r u sure that customized UK fw supports voLTE and WIFI calling? the switches are in the settings? because I have the same model but with eea customized and have no volte or/and vowifi switches.... My carrier supports them btw
I've been told the customised SEA also has Volte and VoWifi wnabled, but I never got any joy out of it when I flashed it into my HK BC72 device. I have tried the previous firmware revision of the UK one, but nothing there either.

So if I flash it to my XQ-BC52 will it affect anything? I don't want to lose anything, but I want to use volte I have no idea why it isn't enabled when all of the carriers on my country support it
I would first update it to the newest TW Firmware and check if it works (so you can update, without loosing personal data).
If it still doesn't work, I would try the HK firmware, because of Over-The-Air–Updates (OTA). I have VoLTE and VoWifi in Switzerland with this firmware.
If it still doesn't work, try the BC-52 firmwares (but you loose OTA Updates).
Please just check after flashing a new firmware if you have the functions. If it works, first do a repair with Sony Companion before starting to install everything (like apps, files....). This makes a clean install and avoids a lot potential of failures/problems.
I bought the phone in Etoren and it is the model XQ-BC72, I live in the UK, and the update I received via OTA and is installed is 61.1.A.2.211 release-keys. you shouldn't, I guess Sony recognizes you're in the UK and installs the correct one

You won't lose your data if you explicitly tell it not to clear userdata off your phone, if that's what you mean. If, however, you're referring to certain functionalities I sometime hear of getting lost, then I myself haven't noticed such with all versions of firmware I have tried out so far.

I've yet to do a clean install, the way you have described it. I guess I'll do it just like that when I've given up on trying to activate VoLTE and VoWifi on my phone. It's interesting that your Hong Kong phone has that function over there. I suppose there is some substance in Sony's insistence that the one's network provider be engaged as well.
I was considering getting the Xperia 1 IV which would be a nice upgrade from my Xperia 1 II but with volte not working it would push me away. I managed to get it working on my Xperia 1 II by simply flashing SEA firmware. It was straight forward and has worked flawlessly with OTA updates. It doesn't look like the Xperia 1 IV will work that way. Even if I was to flash SEA firmware it looks like volte still wouldn't work. Come on Sony sort this problem out
