Hello! I just started developing my custom rom (for education purposes), and I played a little with the kitchen, however i'd like to know how could I update the Android version of the custom rom from 4.1, to let's say 5.0 or at least 4.41(I saw other people making things like that)? I use the stock rom as the base.
You can't update the Android version of a stock ROM. It *may* be possible to port a stock ROM from a very similar device, but the true way to get updated Android versions is compiling from source.

hi very noobish question but im confused to what a rom is? I have rooted my s2 with a custom kernel and have read about roms but have no clue what they are.
A ROM in this case is basically the Operating System files. It contains all the files required for your phone to boot into a flavor of Android. ROMs come in many variations such as vendor specific ROMs like Samsung's TouchWiz or ROMs that are compiled from the Android Open Source Project using the source code such as CyanogenMod or MIUI.
Furthermore, ROMs built or cooked by the devs contain many tweaks and optimizations that are not found on the Stock Firmware/ROM and are, in most but not all cases, better.
Hope that helped
Basically a ROM is an Android system image file, which contains the operating system and some applications.
The STOCK Roms are created by the device's producers, like Samsung or Lg, modifing the original Android ROM (I think it's called Vanilla) to give personalizations to their devices.
Then ther are the COOKED Roms that are created from Android users in order to change and quite always to improve the experience on a device, like Cyanogen or MIUI.

A ROM is:
http://bit.ly/xLMVUT
Literally it stands for Read Only Memory, in this case referring to the phone's internal memory where your firmware/apps are stored. When people say they're flashing a new ROM, it means they are flashing a new version of the firmware onto their phone - the two terms are interchangeable.
A custom ROM (firmware released for the phone by anyone except for Huawei) might have performance tweaks, new features such as overclocking and so on. I believe the most popular custom rom for your phone is Cyanogen 6 or 7, which are both vanilla android firmware.

Google is always your friend. (No offence at all. Just needed to fill 10 character requirement).
Is there any site that i can find out to which models can i official and unofficial install the new android 4.0.3 or newest?
A lot of thanks.
clockworkmod.com and under rom manager it will show you all roms for your phone. if your unrooted google it
I would say this is the best site for that. Just find your phone and see if it has been developed for it. 4.0 can't run on everything without a bit of tweaking on a phone by phone basis. The developers on here do that for you.
It is hard to unlock any android mobile phone to install it a rom that is unofficial and if it is easy BEFORE i installed the new unofficial rom is there a way to make a COMPLETE BACKUP of the android phone so anytime i want i can make a COMPLETE RESTORE to factory defaults with official android version.
A LOT OF THANKS FOR ALL.
cyanogenmod.com
Device compatible with CM9 are Android 4.0.3 IceCreamSandwich
To which sites i can see the OFFICIAL android 4.0.3 supported mobiles phones?
The samsung galaxy s plus i9001 does it support it?
And if don't where is the way to install an unofficial android 4.0.3 for samsung galaxy s plus i9001 phone?
Not as such...
I haven't found any comprhensive listing of ICS ROMS + supported devices.
Your best bet is to start from your device and find which ROM's (if any) are out for it. Some devices may never get support, some already have it, some are in between.
Much as I love Cyanogenmod, I can't get a functional CM9 (that is, ICS by Cyanogen) that will work on my Nexus S 4G. But I did find a list of ROM's for Nexus S 4G and by elimination found one that works flawlessly.
Be careful, follow steps closely, and RTFM first!
hi..
i want to know if that it is possible to downgrade any android device without problem ..??
thank you...!!!
I suppose that any android device could be theoretically downgraded to a previous software version. For some devices you can find even s stock Rom, based on an older version of android, so that everything would very likely work... But, if your phone run android 2.3.7 and no stock Rom based on 2.3.3 exists, it won't be easy to find a custom rom based on older software, apart from the need of rooting the phone.
So you would have to build it from source (not easy at all) or trying a port.
In any case, most developers work to get the benefits of the latest software and I think that nobody works to go back to outdated software.
Most of the time you will only be able to downgrade to the first version of android that was shipped with the device (As it can be hard to back port drivers etc) for example my Note was shipped with 2.3.3 so I could not downgrade to anything lower that that
Yes, I believe it's possible to downgrade your device. You just have to flash some special ROM (with older Android version).
So, I've got a UK Samsung Galaxy S3, and only recently, the carriers have started to push out Jelly Bean to the device. Only Three has done it so far, but, I'm sure my network will follow suit soon.
However, I literally have just rooted my phone. I used the guide which Chainfire provided in the forum - so, CFRoot 6.4.
I have installed CWM, and also TeamWinRecoveryProject - since I preferred TeamWin's interface, and the videos which I saw of it spoke highly of its capabilities.
So, when the Jelly Bean update does come out for my carrier (EE), will I be able to keep my root? I read around on the internet that if you have CFRoot kernel, you can still perform OTA updates (EE disabled the option, anyway, sadly) without losing root.
If so - perfect.
If not, though, would it be perfectly safe to just let Samsung Kies update the firmware? I understand it will remove root capabilities, but some people have posted about conflicts arising when flashing back to stock due to the install custom recovery.
Would it be easier to just install a ROM? I'm looking at CM10, and Paranoid Android. Both are JellyBean 4.1.2 ROMS. If I install them, would that mean that my phone would update to 4.1.2? I understand these are variations, but, is flashing a rom with a higher firmware number the equivalent of updating software through OTA/Kies?
Thanks a lot for your help! Rooting newb, here...
You don't have to think like that.
Samsung official roms are not the same than AOSP (ie pure google source based) roms, like CM, aokp, pure aosp.
In Sammy roms you'll find different framework , all the samsung apps that can't all be installed on aosp roms. You must think about what you want from a rom.AOSP ones are more fast (look at the size of downloads... between 800 MB and more than a 1 GB for most sammy roms, less than 500MB for others, even less than 200 for some), each of them have specific design and features.
You can have 4.1.2 by flashing any rom now, I think most of sammy roms are now based on latest uk Sasmsung JB. Changes between 4.1.1 &nd 4.1.2 are minimal and most of them under the water for end user.
For me rooting and installing CWM and wanting to keep pure samsung offcial rom is antinomic. The spirit of rooting is to get rid of imposed manufacturer choices.
Don't think about numbers but about features.
Hi,
I rooted my gs4 (MDK) Kernel because I didn't want to accept the update and not have the option to do what I want with my phone. However, I like the stock ROM and like the features of TouchWiz. As new versions of Android (4.3 and eventually Key Lime Pie) come out, will I be able to flash stock roms with touchwiz from this site, or will i have to wait around for Verizon to come out with an official release?
Is 4.3 available anywhere now?

Yes, most likely you will be able to flash pretty much all versions of android as long as the device is compatible. There are a lot of great devs out here who develop TW roms and AOSP roms. To answer your second question, there is a 4.3 rom floating out there somewhere but it doesnt work on our phone.
