do i need a special ROM? - Android Q&A, Help & Troubleshooting

I want to buy a VIVO Nex s but i heard that Fun os has a lot of trouble in Europe. I also know that vivo normally doesn't release the kernal sources so my question was, do i need a rom specially made for this phone or can i use a general custom rom that works for almost all phones?
sorry for the noob question but i'm still new to all of this.

[Q] ICS default Stock UI on Galaxy S2, Is it possible, How ?

Hi All,
I am new to this forum and also to this Smartphone world
I am planning to buy Galaxy S2 , but want to use ICS Stock UI ( I can wait for official ICS update or use some ICS ROM ) , but what I want to know is that how can I use default ICS Stock UI on my Galaxy S2.
And another question when we use unofficial ROM on our Android phone , what are the risks we should consider in terms of our personal data security and also the stability of our phone ?
Thanks,
Maverick

If you do some reading around the SGS2 forum, you'll find all of the information you seek. Or you could try google...either way, the powers that be here at XDA aren't very friendly to those who don't bother trying to research, read, or use the search function. I'm trying to be a bit more personable.
At the moment, ICS is in either the Alpha or Beta stage...meaning that it's still buggy and doesn't really function as a daily driver yet.
To get ICS right now, you have to flash a ROM...which involves root access. The risks are pretty high. You have the risk of bricking your phone, if you don't read the instructions and follow them exactly, which isn't always easy because you're not very likely to find exact instructions for your specific phone (the hardware specs will match, but the ROM/Radio/Modem numbers may be different which can lead to confusion). You also run the risk of voiding your warranty, which is a pretty significant one.
I flashed an ICS build yesterday, and then my S2 wouldn't charge. I eventually flashed back (thank God I had made a backup yesterday, and 2 days ago as the one from yesterday didn't work!)
As far as security goes, nothing really to worry about. Dev's don't build in Carrier IQ and don't really want your personal data. But the flip side is, that they don't get paid for what they do...so if you have a problem or 'eff something up, you're pretty much on your own. You can ask for help, but again, sometimes the dev's don't want to be bothered with a question if it's already been answered or if you could've found the answer by searching for it. This is where it gets rude, sometimes.
That's the long answer. The short answer is READ, READ, READ...everything about your phone and flashing ROM's. Start at the beginning of the forum, as that's where the 'stickies' are and work your way thru. ICS will be released officially and stably later.
Hope that helps.
Thanks ,
I have googled it and read some threads on this forum and on others as well... thats how I came to know that you can root your phone with unofficial ICS ROM... but wasn't sure that in that case , will I get ICS with TouchWiz or Stock UI...
And 2nd thing that if I screwed up what will happen to my personal data...
anyhow thanks for replying my (dumb ? ) question

[Q] Need help

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

No best no right you pick a method .
2. Do I need to unlock bootloader? If so, what's the easiest way?
So you dont even bother to read the basic faqs and guides .
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.
BEST ROM posts are banned but you wont know have you have not bothered to read the rules or the faqs and guides .

Thread closed. I think the responses above cover most of it
Please use search before posting and don't post Best ROM questions, they are frowned upon.

developing custom rom for G700, all xda veterans please help me!!

Actually I have many question
I think when a newbie like me start to work on rom development then there are several questions arises in mind basically like what I am going to ask here, my purpose is to get all this doubts cleared before starting so that I can start to focus on things. I don't know if my questions will help other newbies like me but it will literally help me a lot .
I am trying to develop a custom rom for ascend g700 as i have seen it among the most hated device among developers , no one want to do anything for this phone and it can accomodate a lot of upgradation. I have seen g700 users begging inside CM forum to build a latest ROM for this device, I have also seen g700 owners begging on huawei website to upgrade their devices but huawei doesn't even feel like to give a word to it. and I feel really bad about this .
So i just want to build a good looking, working, clean, latest by look and feature rom for Ascend g700 for all users, there are various reasons why I want to do that:
1) One of the biggest reason why I am here is I want to see g700 users smiling with joy that finally somebody has updated their device, I want all g700 owners to feel worth buying the device.
2) No working custom rom is available for this device yet.
3) No Cyanogenmod rom available.
4) This device configuration seems potentially great which literally needs update (atleast up to kitkat).
5) And personally I don't like UI emotion of this phone besides that google play store has some bug which makes icons background looks black which is a sore to eyes, Huawei did nothing for this device yet except just earned the bucks from it. I hate the companies who are ignorant about their customers.
I don't want to bore anyone reading my thread but i have lots of questions to resolve before i start to develop something for this device and I hope i will succeed.
Okay so let's get started with my questions, all veterans are requested to kindly share their vast knowledge and help me understanding the facts. thanks in advance .
Objective: what i am trying to do is, trying to find out the latest possible (Lollipop) rom which I can use as base rom to flash this device (Ascend G700) or just build a custom one fully working.
1 First: Are there any neutral latest android rom versions are available from google official websites to start using on any device or to start develop it for any particular device?
If "yes" then from where i can get it?
If "No" then from where the companies get their android roms on first hand as a clean plain base android rom to make it their own rom?
2 second: Can i just install any rom of any phone and it will start to work?
If "No" then what maybe the problems that I would first encounter?, what can I do to fix that any such known problems?
3 Third: I have heard about porting rom by changing things inside rom like replacing kernel of base rom with my stock rom, Kernel of my stock rom (4.2.1) can work with lollipop rom (5.0.0)? if yes then which lollipop rom would be best to use for (G700) and from where I can get one?
4 Fourth: Can I use my old kernel, camera and radio from stock rom in newer lollipop rom will it work? is it possible to do that?
5 Fifth: Can I use any kernel on any phone? or there are any specific particular to device types? or is it necessary to use the old kernel?
6 Sixth: If I flash my phone with custom new rom the radio will also be flashed with it automatically? even if I doesn't want to? How would I know that the rom i am going to use contains the flash files for radio also? and can i remove that? and use rest of the rom?
7 Seventh: If i flash my phone with new custom rom what are chances that it's camera will not work? or radio maybe affected?
8 Eighth: What can i do to port my camera from stock rom to new custom rom which I want to flash. the camera of old rom (4.2.1) can work with lollipop (5.0.0)?
9 Nineth: The device is a dual sim, any special thing to keep in mind before flashing a rom? a rom should necessarily be valid for dual sim? are there any specific types?
Please all the veterans from XDA are requested to provide inside to all these questions of mine, so that I can start working on my custom rom, I seriously want to upgrade this phone please help
Any help from anyone who knows anything related to any question of mine are welcome to share their knowledge.
Thanks in advance .

HTC M9+ Supreme Camera Edition ( M9px)

Hi everyone, I got this phone the last November and I am still waiting the Android 6.0. This phone is quite new, was released on october in the Oriental Market. I personally think that this device is very powerful also if he got the Mediatek Helio X10. Anyway, I would like to know if anyone already have this phone with Android 6.0 or is there is some Modding Rom available for it. I will really appreciate the help from the moderator and from the developer.
Thank you very much for your time and have a nice day
Is there any chance to talk with any developer of the xda forum to ask and maybe help him for make any firmware upgrade? I mean I would like to be happy help us giving what they want like the phone firmware in itself, kernel, everything.
Hi
Need Custom rom for this model HTC M9PX HIAUR_ML_TUHL
Hi guys, I was wondering if anyone of you has or know where I can find the stock original Rom of Taiwan version of my HTC M9+ Supreme Camera Edition. I will prefer find the android 6 version, but does not matter to be honest, also the android 5 is fine. I want just a clean rom without any Chinese useless app.
Thanks in advance.

[Q]where can i find Custom rom for C6843?

Hello guys i'm trying to find a Custom rom for my ZU C6843, it's really difficult to find a good rom for this version because it's a Brazilian model, but i hope to find one because my current rom is crapy, it slows down the phone and it's almost impossible to use it when it gets hot, i already checked it out and it's not a hardware problem, i would like to know the difference between this model and the others, and if i can flash others model's rom, like 6833's or 6802's rom, thank you for your time.
