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any case, most developers work to get the benefits of the latest software and I think that nobody works to go back to outdated software.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).

This seems like a long shot, but I'm wondering if there's any way to install an older version of the Android OS. I know it seems counterintuitive to want an OLDER version of Android, but it'd be really handy for app-testing purposes if I could switch between versions of the OS without resorting to emulators. Please let me known if you have any ideas.
P.S. I only have access to Nexus S and Galaxy S II phones right now, which both shipped with 2.3, so flashing an original, pre-update ROM isn't an option.
Well you can only downgrade to what's available. The phones only came with 2.3+ so it's not like you can put 2.1 or 1.6 on it. There wouldn't be any support as drivers weren't written for those versions.
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!
Does any one know of a step by step guide of how to install the latest version of Android on an HTC Desire S?
There is plenty of information on Google but i cant find a detailed guide that includes how to root the phone first. The HTC Desire S i have is currently running Android 2.3.5.
A couple of questions:
- Does the Android version depend on the spec of the phone? (i.e. does the phone have to have a specific amount of memory or specs for me to be able to install the latest version on the Desire S)
- Does the phone have to be rooted first before i can install
- If i do root and install the latest version, will i be able to revert it back to its original factory settings?
- What does "installing a custom ROM" mean? Is this the same as installing a different distribution of Linux or a modified version of XP?
- What is the relationship between installing a custom ROM and updating the Android version? Is it the same thing?
- And finally, are these custom ROMS safe? Do i have to install a custom ROM to be update the Android version and if so, how do you ensure that when you update to the latest Android version, you are not installing a version that has modifications to record personal information e.g. your email or paypal logons?
Thanks.
up.. this is also my question..

thanks before for your help
[Q] How can CWM be built in a kernel?
Well, the difference between and old version and a recent one is that the newer version has more features and maybe some bug corrections. Just like Windows 7 and 8, or iOS 6 and 7...
It's pretty hard to update your phone by yourself. You would need to learn about bootloader, firmware, rom, recovery...
And then, you should have a custom recovery. You should port Android 4.4 for your phone, and flash it through the recovery.
And maybe you would need to unlock the bootloader.
PS: What phone you have?
Sorry for my bad english.
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.
