[Q] JB custom rom for KK device? - Xperia Z2 Q&A, Help & Troubleshooting

Hi guys!
First I'd like to say I'm sorry for asking what may seem as a very trivial question, but after searching the web for a few hours without finding an answer, I turn to you.
Simply put, I'm curious to know if it is possible to flash a JB-based rom onto a device delivered with KK.
The reason I'm asking is of course out of general interest, but mostly because I would like to flash Pac rom 4.3 onto my Z2.
I've just installed the KK version (rc3, which seems to run great, btw), but I miss the divided settings (mostly hybrid engine) from 4.3.
I thank you beforehand for taking your time. If the answer requires more typing than you have energy, I would very much appreciate it if you could point me in the right direction. Also, if you would care to give me a tip of an app with similar function to hybrid mode (dpi and...aesthetic settings in general ) that would be great.

You can put anything on any device, all you have to do is modify it or build for that device
Of course the doing part is a huge task.
Try bugging a developer on porting what you want or try learning how your self

Oh is that all I have to do?
I was afraid that was the way I had to go. But porting is really the only way to do it, right?
I just found a Tablet UI for KitKat "ported" from JB on Xposed. I am going read up a bit on it, and try it out.
Seeing how it's not the proper way to do it, I will probably try and build a port.
Thank you for your advice! Much appreciated!

I'm sorry if I came of as ungrateful. That was not my intention at all. I was just being cheeky.
I truly appreciate your help, and I will look into it more. I started a thread about it in Z2 General Q&A (link: http://forum.xda-developers.com/xpe...rom-4-3-z2-t2953739/post57057282#post57057282). So far no one has answered, but I'll keep looking.
Thanks again

[Q] Howto Rom modding

Hi All,
I have started using X10i a month or so back and so far have been flashing many ROMS and finally settled on CM6 mod by [Cyanogen6.1.3]gingerbread[v01] : by http://forum.xda-developers.com/member.php?u=1022236
However now i am moving to the next step which i thing would be to mod my own ROM. however after looking at the whole forum i was not able to find some straight forward startup guide for this.
can anyone help me on this.
It takes years of learning coding... only by creating this thread, you've shown us that your uncapable of doing that.
ohk so i have checked again the whole forum

Well, are you interested in modding the ROM in its core,
or applying modifications like themes, framework-res changes and tweaks?
Because if the latter is the case, it's quite easy.
You just open the ROM zip and tweak yourself away!
But if you actually want to build a ROM, then, as it has been already said,
it is not easy.

Why upgrade from stock?

I apologize if this subject has been covered before but my searches did not turn up anything. I am an Android newbie with a new Tab 10.1. It seems to work quite well but since the OS allows for easy customization and many people do it, I feel like I am probably missing something. What is there to be gained by moving away from stock? With so many options out there, how does one choose between them?
If there is an article or forum thread that covers this subject in language that newbies will understand, I would really appreciate being pointed in that direction. If such a document does not exist, hopefully someone can answer the questions here.
Visual mods to performance enhancemants are why people tinker with Android ad their devices.
Read as much as you can before you do anything or make any changes.
As far as which is best. That's up to you. Try them all until you find what you like.

I agree Beezer that reading is the key to android world. try as much as you like because it is very hard to brick android devices
Thanks guys, I am sure that you are right about reading as much as possible. The problem is that I am so green that I do not even know what I don't know. Any suggestions on where to start my research?

Galaxy Task ftw...
I have been running Task's roms since I got my tab. His current rom GalaxyTask v6.3 is as smooth it gets at least until an ICS variety is available.
Link is in my signature.
I think the thing to do is just use your Tab for a while before getting stuck into rooting it, give yourself chance to discover it's shortcomings (if any), if you feel it isn't quite up to par, look around for the most suitable fix.
I've had my Tab since August and I haven't yet felt the need to root it, I do keep looking at the threads in the dev section though, one day I'll get tempted but that's not today.
I'll try and hold out for official updates, unless I get really bored and decide to risk my warranty status.
turn to the darkside of rooting and adding a rom. at first i was nervous but after you get a feel of the roms like tasks roms.. omg there is no turning back. it is like night and day and you'll never want to go back to stock

Developers Mind

Hi Guys
This one thought has been going through my head all day and all yesterday, and when I say it to people with android device which is custom ROMed or rooted, they have a little chuckle.
Now don't get me wrong, I love that the desire X has a development team for ROMs and what not, and I love every one of them (xpirt, atis112, MaartenXDA, neXus PRIME and whoever else I missed), but I can't help but think this is what they think
"Alright it boots... lets do something else"
Love you all <3

That's not true at all.
First of all, only one of the people you mentioned is a "recognized developer" and he is in school busy with studies. Dont expect him to work full time.
Secondly, I was a learner for just about everything but became RC here on desire x, not before. (Although you missed prototype, and xpirt and Maarten also fall in the same category, even higher then me, i guess.)
Thirdly,
you people got these fully working things
1. CWM
2. TOUCH CWM
3. TWRP
4. FULL SENSE 4+
5. AOSP MODS and ALL OTHER MODS
6. Custom Kernels (LOTS OF THEM, with unique)
7. MIUI (sense-based)
8. and many many many things i missed. (special mention to sense 5, apart from BT bug, which will get fix soon)
Above were almost fully functioning products. Now lets mention the rest.
1. CM9
2. CM10
3. AOKP-ICS
4. AOKP-JB
5. PARANOID
6. CM10.2
and many more i must have forgotten.
All of above was done by 1 dev, and others good at porting and compiling. Thats more than you should expect.
Your thread is not the first one like this. Sometimes people show amazement at slow pace, some show sadness, others are ruthlessly blunt and rude. I understand that. But what we need are more people willing to learn the stuff.
Everyone will work what they like... if i want sweep2wake on my phone, i dont care how many others want overclock or undervolt, i'll concentrate on it. and when i start work, i'll get plenty of help from other communities as well.
I hope you get my point.... for future reference, whenever someone opens this kind of thread, i'll copy paste this same post....
Or i'll ask a MOD to make this a sticky.:silly:

Look at this from another point of view, if you'd be the developer,
sometimes you'd be getting pissed when you try to bring something to work,
but it won't work after you've spent 3-4 nights, lets say a week at it.
They need variety too!
fixing bugs isn't just like catching them

Not being an ass or anything but that part was really pointless. If he/she could have made Roms they would do so.
And as for others that keep asking questions like this should really just buy another phone. And use Roms on that.

@iTz.Ranga if you have problem with devs then why don't you start your own development of a rom? I don't think so its hard enough or impossible.

I'm sure he didn't mean that he has a "problem" with the devs (and other contributors). More like wanting to know why so many roms are seemingly discontinued before reaching stability. And the simple answer is that these roms (PACman, AOKP, etc) are CM-based, so they cannot be stable until we have a stable CM rom
But attempting your own rom is also a good suggestion. I'm gonna experiment with some development/porting after exams, though right now the only experience with programming I have is web/database/object orientated (VB, ASP.net, SQL, etc)
Hope it's not too hard.

No. Pfffftt... Yeah you're right "Alriight it boots.... (Except you got the next statement wrong) lets go fix the bugs before we do something else" and NeXus Prime is right, almost most of the ROMs here are done by one dev Sense 5, Full Sense 4.1 and 4+. CM 10.2, MIUI, PA and more
Thread closed
So there is a member with one post deciding he has to judge the developers on this forum. That is exactly what we were waiting for...
This thread is extremely disrespectful and we can easily do without it. If you don't like the roms the devs offer here, proceed to make your own.
If you can't, just take what is offered or move on.

[Q] [ROM] 4.4 i717 Question

Hey everyone, I'm new here and have been trying to find out what's going on with the i717 in regards to kitkat rom development. Anyone have any updates or know how soon we can expect to see some nightlies or any types of builds?
Thanks!
Has it even been released yet?

I will edit my original post here cause I was a bit of an A-hole. this was you first post and I didn't want your first impression to be as nobody here wants to help. of course if you had already read the previous, than I am too late and can only apologize.
a few spoken rules in one of the threads for newbies here.
1. run a search, maybe the question has already been asked before
2. read, read, read
3. help yourself first, as nobody is going to do the work for you.
there are thousands of people that are more than willing to help here, but you should be mindful of repeating questions as some folks can get irritated. it is usually someone that asks a specific question about an issue that was just addressed 2 post up or on the previous page.
making a personal request for an immediate feature that may have just been announce can also annoy some developers. some to the point where they have stopped developing.
good luck and remember to read

Thanks, I didn't read until after the edit, however from browsing around here I was worried I would just be told to shut the **** up etc...
I have tried looking all over the place for info on a 4.4 rom and if people are working on one for the i717. So far I can't find anything. I was just wondering if anyone knew if the phone would be getting a ROM or left behind.
Our latest official release was 4.1.2.
As you can see, we now have ROMs on 4.2.2, 4.3 and 4.3.1. I have not seen any devs "promise" a 4.4 rom, and I don't expect them to.
But, the 4.4 source just dropped few days ago, and I am pretty sure that they are looking at it, at the very least. If history is any indication, I would say we are going to get 4.4 roms eventually. Developing a rom is hard work, so please just wait.
Asking for an ETA might be irritating for devs, if you are not contributing to the development. And if you are contributing to the development, you should already know the answer to the question.

Sorry, I don't mean to annoy anyone. I only came here because no other place had info and was told to go to XDA. I am not trying to rush anyone and I know these things are a ton of work. Like I said I was only wondering if people thought at some point 4.4 would come to the i717 not plz give me rom now.

He posted the preview in General. I haven't been able to flash it personally because I use TWRP (and only CWM works at this point) but you're welcome to check it out. Flashed CWM Recover to try. P3 ran well, although obviously a bit buggy. P4 is out now with less bugs--both ran smoothly...well enough that I'm happy using it as a daily driver.

Yes, relative to ASOP/CM, the ones that I am aware of: JamieD81 is already working a version of CM11 plus his stand-alone Uber kernel and I believe that you will see Liquidsmooth (Patch_Adams) and Hellybean (ThdDude) come up with their versions.If you have not yet tried them, they all have excellent 4.3.1 kernel & Jellybean builds.

I would be happy with 4.3 if MHL works to use Chromecast features.
Would love to recycle older devices and connect to TV or Projector permanently.

[Q] Helping a dev with rom

Hi,
I've been using XDA for a while now, and with the help of many amazing devs I've managed to flash custom roms to all my older devices no problem! Recently I've been waiting for a dev to make changes to an existing kitkat rom, to fix a bug and I'm becoming a little impatient. I know everyone has their own lives to attend so I'm not complaining, rather I'd like to try and help this dev with the problem as I have quite a lot of experience with Android apps. I've read up on the CM wiki the sort of things that are involved in debugging roms etc. so I know that I'll only be able to help with the framework (as I know no C/C++).
So my question is, are there any ways I can help them, and will my help be appreciated considering the skills I have? I also have a decently fast computer too so I have a feeling I could help with building the rom.
Thanks.

Ask them. Or ask their permission to use their ROM as a base, make some actually meaningful modifications, and release it. But as too your "skills" I didn't see you state what they were, and if you have to ask then probably not. Don't stop reading/learning though, you'll only get more knowledgeable.

Ok, I was thinking along the lines of making modifications and then pushing them to a git repo. Maybe they don't have one, I'll go ahead and ask. As for my skills, I was saying in my last post that I have quiet a lot of experience developing Android apps. Do you know what % of rom editing is Java based vs C/C++?

There is no hard/fast guide on what "rom-editing" is. Are you wanting to contribute to kernel development? Better know a lot of C. Wanna roll a cool application for a ROMs special settings? Java is what you want. What I'm getting is you know more Java, so why don't you write and application that you think will solve a problem, then talk to a developer about including it in their ROM?
