[Q]

Hello there , I want to ask about custom Roms as cyanogen mod and PAC and all those teams out there.
First of all ,, the android that they make is similary to the stock one that I can get it from Google website to open it on jdk simulator. Then what is the deal in making custom roms??
And what about Samsung Galaxy Roms features.. Are they closed source? So there is no one can steel there features and use them in other Roms ???
I wish some one answer me because I am so confused about this .. Thanks

So to start from my understanding of the beginning, Samsung or HTC or LG and such will plan out a device, they put all the stuff they want on it ( as in the battery size, the specific GPU and CPU), and towards the end they slap on what version of android they want. this android is Stock like what you see with cyanogenmod or Aosp roms ( they are almost stock but with a few modifications like CPU governors and I/Os) from there they are able to put in all the features they want to feature on the device (so if you think about it, Samsung makes their own Custom rom for the phones but its very professional and are made for the General population where we are the few developers that aren't very professional.) like for Samsung, you will only see S Memo on Samsung phones (so yes Samsung Features are closed source if you develop a rom you are able to put features that come from the Stock rom you get when you buy the phone.), its possible to put s memo on other devices like one of HTC's, but is sorta illegal since Samsung owns s memo. for custom roms, we as developers are able to put stock android features into a rom because Google made android open source. (its not quite open source in some areas) now if you have a Samsung phone and want to make a rom based on Touchwiz (the normal Samsung Ui) or HTC phone and want to base a rom off Sense (Htc's Ui) we are allowed to do this only on these specific phones, otherwise making a Sense rom on a Samsung phone would be illegal and they would ask you to take down a download link. im sorry you had to hear me rant and i hope this made sense! if it sounds like i left anything out please ask.

OK I understood a part, but im still confused about Cyanogen mod part .. I mean what is that thing that they do and others cant do so every Dev make a ROM sayed it based on Cyanogen mod ??

[Completed] Rooted HUAWEI ASCEND Y220-U10 Custom ROM Compatible?

Hey guys I am fairly new to android and really new to this rooting and custom rom thing and I've been doing my research with what a rooted android w/ custom rom could look like and what it could further do.
I was hoping that my rooted phone is compatible with Custom Roms like Cyanogen Mod, AOKP, etc. Unfortunately my phone isn't listed in any listed devices in the well known Custom Rom Sites but I still proceeded with installing Cyanogen Mod since everyone seems to be using it. I don't even know if there are more of these eye candy useful mods that makes the ios look miserably locked up while hoping at least one of these custom rom is compatible with my crappy awesome phone. But upon installation process of Cyanogen Mod WITHOUT awareness that it really isn't compatible, it stated in that page that I could (STILL)use their Custom Rom at my own risk. Beyond that I stopped the installation process in fear of destroying my phone.
I was wondering whether you guys could enlighten me about the compatibility of Huawei Y220-U10 to Custom Roms. I've seen Huawei Y210's on youtube that's using a custom rom but unfortunately ALL of them who's demonstrating their phones are speaking in Spanish. I also installed ROM Installer but I can't seem to see 'FEATURED'? Maybe because it's the free version?
Now I am willing to take the risk, starting from the bottom meaning derooting my phone, wiping it clean, rerooting it and flashing that Custom Rom but I'm seeking advice from much more experienced users because if you guys tell me that it is a BIG NO NO I guess I'll just have to stick with the Go Launcher and wait until I get a much better, stronger, faster android smartphone which has a friendlier compatibility to everything android. And how come I can't access facebook nor yahoo from any web browser in my phone? is it a virus? Please clarify my theories.
Much Regards, Jom
P.S. Phone is running at 2.3.6 and rooted with Kingo Android ROOT

Hello @Jom Apa Welcome to Android / XDA!
"BIG NO NO!" You can't flash ROMs not made for your device because of the underlying hardware incompatibilities. You might completely kill your phone.
Give me a few minutes while I search for ROMs you can use
UPDATE: Unfortunately I haven't been able to find any custom firmware for your device nor Github entries for the chipset used. Seems you'll either have to stick with stock or create your own custom ROMs there are a lot of support here on XDA, Let the learning begin!
Cheers!

[Completed] [Q] I want to flash a custom rom but I'm worried about security/privacy issues.

Hi,
I'm kinda new to android, I've rooted my phone (Samsung Galaxy S2 Skyrocket sgh-i727r / on jellybean 4.1.2) and I'm ready to flash a custom rom (SlimKat to be specific). I feel the stock rom can be "trusted", but can a custom rom be trusted to be secure and have privacy? I'm concerned that a custom rom dev may have added anything to the rom to be a security or privacy issue (where they can listen in on texts or phone calls, steal contacts or even steal passwords).
What are your thoughts?
p.s because I have limited knowledge of android I can't look through the code to inspect it.
I hope someone can please help.

Hi,
Thanks for using XDA Assist Well no Developer adds anything which may effect your security if that was the case then no one would have used Custom Rom's... Custom are too build from source and in all Rom's thread they link the source used but OEM never release it hence you wont be able to find but Custom Rom's have their source and all security previlages even Root has all security option to suit to users needs.. There is no such issues no one tracks nor steales anything developers have a lot of things in real life and in Android world they enhance Android Experience to full potential so that users can enjoy it
End of the Day its your choice
Good Luck!

Several Noob questions about custom ROMs?

Hi guys,
I always read in the Xda forum but never wrote or asked a question...usually someone already asked them.
so I have the Mi 5S PLUS...but I hate the miui UI. can't get used to it. And yesterday I finally found that there are custom ROM for this device.
So I got few questions.
1. As far as i know, the source code hasnt been released but should be released soon. should I wait for a ROM that uses the source code?
2. I see that the most popular costum ROMs for this device are - Lineage and resurrection remix. In terms of battery life, stability and bug free rom. which one is the best?
3. I see there is one ROM with the tag [OFFICIAL]....does this mean it uses the source code? if not, what does it mean?
thanks a lot to those that answer

1. Source code is released but rom based on source code are not released yet .You can use them but their are some bugs,
2.You can check yourself
3. Official means official rom from lineage team or other maintainers just like Global MIUI rom from xiaomi is official while xiaomi.eu is unofficial .
You can check for source in rom page for more info about what device tree and source code it uses

The reason that people don't recommend one over the other is because YMMV. I know I came from a cyanogen ROM with my previous phone and dirty unicorns on the phoen before that (along with a whole set of custom ROMs). In the end though, I found them all to be "similar". Yes, some do some things differently like some offer a lot of CPU governors, while others keep the list pretty tight. Some default with swap space on, some don't use swap space at all (this phone shouldn't need swap space). Sometimes the difference between two ROMs is just the launcher.
For me, I don't really like the MIUI launcher. It feels a lot like an iphone. This isn't a bad thing. Some people like it. I just install Apex (from the play store) and my issues with the ROM were mostly resolved. The only remaining problem is MASS STORAGE. But, based on my experience with mly previous phone, I doubt I'll find a ROM that natively supports it. But I know how to hack my way in and get that going (just need root... which requires an unlocked bootloader... and if I am reading things correctly, you need to wipe everything which I currently not willing to do... but may have found a workaround... going to test it out tomorrow).

Wipe everything is very simple connect the phone via USB cable to PC and via twrp wipe everything then past a Rom on the phone and flash it, that's it

Wiping everything is easy, yes, but I want to avoid wiping if I don't have to.
Got the phone rooted without needing to wipe it (yay), but getting mass storage enabled failed on me. I can't seem to write to the file I need to which confuses me... but that is off topic so I'll refrain from boring you with details on that.
Back on topic, if you are switching to a custom ROM you will need to wipe things. I personally would wait for a custom kernel to come out before you start playing with custom ROMs unless the custom ROM has a feature you REALLY want. With my previous phones, the one that had a custom Kernel as well as custom ROMs was a lot more stable and had a lot fewer bugs. The one that had only factory kernel, the custom ROMs were flaky. They mostly worked, but they did have bugs. If I got a phone call or called somebody and they hung up first, it would crash the dialer and the dialer would fail to start again until I rebooted. Now a custom kernel may not have helped that, but since the kernel was based on a previous version of Android, it was unstable.
The current custom ROMs (that I have seen) are all based off of the stock kernel and not newer ones so I personally do not expect to see much benefit in changing ROMs except having different bloat and a different launcher. Well, at lest for the things I use my phone for. But YMMV.

How do people make custom roms from stock roms, as opposed to AOSP?

Hey everyone, not sure if this is the right place for this, but I hope someone can help me.
I've always loved custom roms which take a stock manufacturers image and add fixes or tweaks. I love roms such as Fulmics for the LG G3.
Now that I've got quite a few phones hanging around in the drawer, I'd really like to try my hand at taking a stock image and modifying it to my heart's content. However whenever I've looked into this, I've gotten a bit lost and mostly ran into guides talking about compiling AOSP.
Does anyone have any guides or tools which can help me modify stock roms (such as LG or Nokia)?

If a phone's Android OS ( aka Stock ROM ) is rooted then it can get changed in any way according to user's wishes.
