Hi, so I am new to the whole android thing and my partner has a new phone so I thought, why not learn something about it and try to upgrade her old one since it's impossible to do normally, let me explain.
So the version in question is GT-I9300 JZO54K.I9300XXELLA and after researching it seems as if the highest version possible is already on the phone, 4.1.2, yet I know a few people that also has a galaxy S3 but they are able to upgrade on a regular basis.
So I want to know can this phone be upgraded in any way? Also how do I know what version I can use? there are so many different versions for each phone
Thanks

There are custom and stock versions of Android 4.3 as well as custom 4.4.2 and 4.4.4 roms. I suggest reading up here:
http://forum.xda-developers.com/galaxy-s3/general/ref-one-user-guide-video-tutorial-t1944196
So let me get this straight, providing the ROM is for a Sumsung S3 GT-I9300 I can put in on my rooted S3 device?
Does the Baseband, Kernel Version or Build number have anything to do with what ROM's I can use?

Yes, if the rom is made for your phone, then it shouldn't be too big of an issue to install. The versions are important insofar as it's not recommended to downgrade, due to the Knox and bootloader "updates" from Samsung. As far as the modem, just make sure it's for the same update (4.4 modems for 4.4 roms, etc) unless the developer of the rom you are looking at suggests another. If they don't mention it specifically in their install directions then it's best to have the one matched to the region you are in for the international Galaxies like the S3.

Hi guys,
I plan to buy on June 14th the Galaxy S2 on Bell Canada network, it will replace my Pre2.
I was wondering if you can recommend me a specific ROM that will get rid of TouchWiz and allow me to run Gingerbread stock. I'm not familiar at all with Android, as I never use it before. That is the main reason why I rather ask the question here instead of searching, as I would not know what to search for.
A little about myself: I'm a Linux head (Redhat advanced + Ubuntu).
Thank you for your your help.
If you realy want to delete touch wiz, you'll have to root your phone otherwise you can't get rid of touch wiz, however you can run a different launcher and having touch wiz on your phone.
Hi Viletung. In WebOS, it takes me about 30 seconds to root the phone.
Yet that retains all the phone settings unchanged, while allowing me to install packages, manipulate data, etc. Is it the same thing with SGS2?
I guess my question is: is it recommended to root the phone? I'm curious if most of Android users root their phone. I know I rooted my Palm Pre/Pre2 phones 5min after I got them. I read on the Internet that certain ROM's are built on stock Gingerbread (without TouchWiz), allowing the phone to save on battery and run much smoother with less used resources. Obviously, if you install a new ROM it will void the warranty.
I'm at a point where I'm learning the basics, so any advice is appreciated.
Hello!
I've installed Lite'ning rom 1.5, which has root access. And to flash it takes about one minute!
When I got this phone, I knew it was possible to root my phone, but I was scared that I would screw something up and break the device.
Now, it's about one month after I got this phone and I must say after rooting the device, deleting some standard Samsung **** (Social Hubs etc..), my SGSII isn't draining battery as it used to do before I deleted some stuff. (Including TouchWiz)
But I have also a JIG, to reset the custom kernel counter, just incase I need my warranty back.
So my final conclusion is; I can't life without root! I like to edit the system icons (battery-, wifi icon and much more).
If you have any questions, I'll try to help you
Rooting, yes do it. It's easy, does no harm, and opens up neat options.
Just get Villainrom which is updated to version 2.0. It's built on android 2.3.4, fixing the 2.3.3 battery drain bug (which occured on all phones running 2.3.3).
If you want your stock gingerbread experience, there is a rom out there which tries to replicate this, but I recommend using a 'better' rom with a custom launcher mimicking Gingerbread. Since there's not a lot of difference than just a different launcher (home-menu).
Most dont root but most are not on XDA and dont know anything bar stock . I would guess most XDA users root .
I'm at a point where I'm learning the basics, so any advice is appreciated.
To a certain extent its been a learning curve for the devs as SGS 2 is different to SGS1 .Expect even more development as the days go by .

Thanks a lot guys for the info.

Thanks for the info. I want to have the latest version of Android, I don't really care about Gingerbread. How do updates work on Android (i.e. updating to Ice Cream Sandwich eventually)? On WebOS, updates are done automatically from your carrier or Palm/HP (if you had an unlocked phone like myself). Even if I rooted my phone, I would be able to update the phone firmware with a simple download and retain the rooted aspect of the phone.
About rooting, what did you used? I'm looking at Odin and SuperOneClick... is there something better/safer? One more time, thank you.
Official updates via Kies over PC only .
Rooting is usually lost on update .
Rooting via Chainfire

Why don't you use it for a least a few seconds before ditching it, there's no aosp gingerbread anyway so you're stuck with it until cm7 comes along.
I want to root the phone and replace the ROM mainly because I heard that TouchWiz is running on top of current OS. I could disable TouchWiz, indeed. The issue is: I do not know how upgrades are performed into phone. From the above posts, I have to do it myself is not an automated download/install like WebOS does it.
So, if a new Android version is released, I have to download it myself? For example, my phone comes with 2.3.3 installed but 2.3.4 is released already. Will my phone ask me to download the latest version automatically upon release? I presume not, I have to download and install it myself. Using logic, that is done by either installing a ROM or getting the upgrade from mobile provider.
Correct me if I'm wrong.

That's correct, and is one of the main reasons people root their Androids so that when a new version comes out we can download it straight away and don't have to wait for the carrier to officially release it, which usually takes a lot longer than it does for the devs here to put something together. E.g. there are a few ROMs already in the dev forum based on 2.3.4, but there is not yet any official update.
Thanks guys much appreciated. I will probably have more questions, once I have the phone on hand.

Android phones get new updates over the air when available, just like web os. Only Samsung does their own thing which is different on the sgs2 than on normal android devices. .
Which is, providing updates through an unnecessary software suite called KIES. You won't see an update available message on your phone.

Just install a launcher fromthe Android Store. There's plenty of good ones like LauncherPro, GX Launcher, 7 launcher. Their all relatively good and fully functional.
OK, I got the phone (16GB model) today from FutureShop and played with it a bit. It is a great phone indeed...
Phone Info (might be useful for devs)
Network: Bell Canada
Model: GT-I9100M
Android Version: 2.3.3
Baseband Version: I9100MUGKG2
Kernel Version: 2.6.35.7-I9100MUGKG2-CL371789 [email protected] #2
Build Number: GINGERBREAD.UGKG2
Now, on with the usual:
Bell bundled the phone with several crap apps like Self Serve, TeleNav GPS (how stupid is that on an Android), Remote PVR, etc.
I will follow your advice and use the phone for now as is, without any fancy stuff done to it (like a new ROM). I would like to get rid of the Bell proprietary apps (physical delete), let me know if is possible. I guess if the phone is rooted it should be easy, the trick is to know how to delete the apps from the phone.
Another question: How do I install the Samsung drivers, without installing the blotted KIES?
I looked for a clean package with SGS2 drivers only but I could not find anything... All I want is to go to Device Manager and point a directory.
I must admit that Android is a totally new experience, coming from WebOS. I'm pretty much lost, heh. I know I sound like a noob, so please forgive me if I ask some simple questions that I can get the answer with a search or just by reading the phone instructions (haven't had the time to read the documentation).
I have a few questions sorry if its a repost but id rather make sure I get a good answer to those questions then any other variant of them.
I got a galaxy s2 a week ago and I feel like the battery life is really bad and the phone heats alot sometimes.... (BTW this is my first smartphone EVER) I was wondering which one of all these custom ROMs out there is the best for the galaxy s2? Which one will give me the smoothest experience with a good battery life and fix that heating problem?
Also, I have the Canadian bell's version so MUGKG2... When I look at ROMs all I see is XXKH3 or XXKE7, etc... Basically how and what version do I have to use/install to get a custom ROM? (P.S I know how Odin works and I know how to root since my phone is already rooted)
And what is the latest Android version possible to get on the galaxy s2? I heard something about 4.0 but I think the latest version possible to install is the 2.3.4 am I right? Also, every ROM is 2.3.4 right? Or do I have to flash a 2.3.4 (or 4.0 depending on the latest version) kernel on the phone?
Thanks for your time and have a good day!!!!!!!

Currently running ICS via XXLPH on a GT-I9100P. Unfortunately, that version doesn't include NFC support, which annoys me, since I paid extra for a phone with NFC hardware.
My question is - I see via the sammobile page that there is a firmware update for my phone more recent than what I have, albeit one with a different PDA to my current one (I9100XXLPH vs I9100PBVLP8).
What exactly does this mean? Does this mean it's simply different software, but still designed to run on the same hardware? If so, it should be compatible with my phone, no? Or are there other things I should be checking for compatibility?
(Also - would that update even help with NFC?)
I recognize that ultimately whatever I do when screwing around is on me. And I realize that flashing a different official ROM is pretty tame compared to all the unofficial ROMs here (though most of them don't seem designed for the P version of the SGS2). But I'd rather not brick my phone at the moment.
Note - this is not a phone I got from a carrier, and I rooted it, so waiting for OTA upgrades is not an option.

make a bkp of ur exsisting rom and then flash the I9100PBVLP8 and see for the NFC issue if it resolves u can keep it else restore the original one back
since pda is the modem if its diff no issue u can always change the same if its not wrk'ng properly for u
Thank you. So all I should care about in ROM flashing is the underlying hardware? PDA and CSC differences should not brick my phone?
You may want to check this out it should add NFC to any rom.

Hi, I have a Galaxy S3 GT i9300. I ordered it online, probably came from Germany since it came with a bunch of paper in German.
Anyway, I live in Portugal, and my carrier is TMN, and I'm really confused on how to root it, and unlocking the bootloader, which I don't know if it's really necessary or not, and then the ROM, which I'll bring up in a moment.
I updated all the way up to 4.1.2 now this is what I want to know:
1. The easiest way to root, I have questions about this cause there are so many ways, and I don't know which one is the best, or the right one cause I don't know if it's unlocked or not, but I'm guessing it is since I'm using a TMN (portuguese carrier) Sim card.
2. Do I need to unlock bootloader? If so, what's the easiest way?
3. Now I'd like to know of a stable ROM, preferably with 4.2.1, or 4.1.2, also I'd like to know if there is any way I could keep the Samsung Apps, and if not, if there is a way to get them back. All in all, I want a clean, fast and stable ROM.
Thank you all.

i would have thought you would root it exactly the same as you would with all other i9300 devices, with cf auto root (http://forum.xda-developers.com/showthread.php?t=1957273) however it doesnt install a custom recovery which you need to install roms. for that a good option is phillz touch (http://forum.xda-developers.com/showthread.php?t=2002953) which is based on cwm after rooting while on android 4.1.2 there is normally a red exclamation mark in the top left corner on boot. this is due to a new bootloader which sammy introduced to help them find phones that have been rooted and sent in for repair. the way arround this is to download the old ice cream sandwich bootloader (i dont have the link but im sure you can find it, i forgot where i downloaded it from sorry ) you may not need this or not be bothered about this so its your choice as for rom it depends on weather your looking for vanilla android or a samsung based rom. however there are no perfect rom it is purely based on your own opinion although a widely used and stable vanilla rom is cyanogen mod (http://forum.xda-developers.com/showthread.php?t=1779426) and most sammy roms are stable as they are not really altered much from stock however i use android revolution and have had no issues with it (http://forum.xda-developers.com/showthread.php?t=1797334). hope i helped in some way and i hope that what i said isnt too confusing thank you for reading
why does everyone want being spoonfed? what happened to good ol' searching? you're asking the most basic questions, do you really think they haven't been answered?
and asking for a clran/stable/good rom is against the rules

Hi Everyone,
I am seeking some advice regarding our beloved Samsung Galaxy 2. I owed this phone in the past and after testing other devices, I am considering to purchase it again. Please kindly try to answer my questions:
1. I have Spinal Muscular Atrophy and I think the S2 is one of the lightest and thinnest smartphone on the market. Do you have any other devices in mind that could be suitable to my mobility issues?
2. I have purchased a few smartphones online (ebay and amazon) and always had difficulties to find one that is “truly” unlocked. Most of them were entitled as “unlocked” but would not work with my sim card. Do you have any advice on this issue?
2b. Do all S2s have the same processors/ram/features? Do you advise any S2 version in particular or all of them are fine?
3. I am interested in those new voice recognition features such as Ok Google/voice and my guess is that the most efficient and reliable versions of it are present on the latest Android versions such as Lollipop/is there any correlation between Android version and Voice recognition efficiency?
3c. Do you think it would be possible to install Lollipop on a S2 and how?
3d. Would it be a simple and “official” update or will it necessary imply a “jailbreak”? Knowing that I am definitely not familiar with this kind of process, are there accessible and straightforward tutorials for newbies showing how to proceed step-by-step?
3e. Would it slower the S2 to update it with Lollipop or create any other issue//conflict/flaw? If so, until what Android version can I update without slowing the S2?
Many thanks for your kind help!

1. Sorry no idea here.
2. By rooting your phone you could remove the branding and use any sim card
2b. The most common version of galaxy s2 is the international one gt-I9100. Depending on the year of when it was made there could be a slight difference in processor. Older processor need more voltage than the newer ones and might not be able to overclock as much as the newer ones. But if you don't intend to undervolt your phone this is unimportant for you. All of them work with 1.2ghz. Which processor type you'll get is some kind of luck I guess.
Gt-I9100 aside therealso are gt-I9100P and 9100g. I'm not sure but I think they work with same specs as the international one (1, 2 ghz and 1gb ram) but they use other hardware and thus it's not as easy to find custom roms like for the gt I9100 I think.
Furthermore there also is the galaxy s2 at&t version. If I'm right this the t mobile version of this phone. It also has the same specs like the other models (different hardware too) but the difference is this phone has no physical home button, which for me, looks better somehow.
I'd suggest to take the international one gt I9100 or the at&t version.
3. Official android version of the galaxy s2 models is jelly bean 4.1.2 which also is required by Google search and Google now. I assume it doesn't matter rather you have android 4.1.2 or 5 regarding the voice recognition.
3c. At the moment it's not possible to install Lollipop on a S2 but it may be possible in the future. You'll have to root your phone therefore and flash/install a custom rom based on lollipop.
3d. Like already mentioned earlier you'll need to root your phone in order to get past android 4.1.2. Depending on your phone model (2b.) It can be extremely easy or a bit more difficult. I'm just used to the international version gt I9100 which can be rooted with an app via one tap. That aside there are various step by step tutorials, as the galaxy s2 is a very popular phone.
If you'll root your galaxy s2 I highly recommend to Google emmc brick bug before doing so.
3e. All official android versions can become slow after some time, especially because of not removable, pre installed apps. With root you have the possibility to remove those and make your phone faster. If you intend to stay on official firmware you should update to the latest (4.1.2).
Talking about getting slower with higher android version is a bit difficult here. Theoretically with higher android version the phone will get faster....at least that's what Google says.
However as already said the galaxy s2 is stuck on 4.1.2. The only way to get higher are custom roms and those can be slow or fast no matter on which android version they are based.
For example cyanogenmod 10.1.3 is the fastest firmware I've had till now and it's based on Android 4.2.2. Jelly bean. Next there's for example aicp rom based on 4.4.4 KitKat. This version wasn't very fast for me. Another KitKat rom, NeatROM, however was faster than aicp although it has same android version.
It always depends on your personal phone, because each phone (or each galaxy s2 in your case) reacts a bit different to it's firmware and also on the way the developer made their custom roms.
You'll have to find out there
