[Q] New hack for performance and power saving - HD2 Android Q&A, Help & Troubleshooting and Genera

Just saw this and curious if this will work with our hd2 and hopefully devs aren't too busy trying it....
"What this hack basically does is changing some partition settings (loopback) to increase write performance and to saver power."

I think the devs are looking into it for sure.
You must appreciate that the devs are also working for free and share their builds with us.
Nothing stops you from developing your own build and sharing it with us.
I wonder if you would also appreciate it if people would 'demand' something from you.
So sit back, relax and appreciate all this fine work from people that do this in their own free time.

i wasnt demanding anything -_-
besides, when i have something to offer to the community, i share it, unlike most of the guys here.

I miss Benchmark..

Sorry guys , if you think this is gonna be flamed again please close it, just wanna give my little point of view,
I miss the benchmark coz at least it can guide me of which to choose ,
it 's useful for guiding and the rest i can judge myself , i will not complain anyone no matter the rom is good or not , thank you all the cookers , this place is Amazing.........
please do not get me wrong in anyway. i just really miss the benchmarks
hope many flashaholic loves this too, sometimes i flash 2 or 3 times a day from almost every rom ,Duttys, L26, Miri, Lost in Asia, Xant, Topix... enjoy..

Benchmark actually do not say anything about the ROM in everyday use. Stability. overall speed are iumportant factors when it comes down to choosing a ROM. None of these are properly reflected by a benchmark.
Not to mention that the benchmarks are flawed at best anyhow. The 'fastest' ROM out there was so crowned due to the filesystem being 'two times faster' than average - I don't know about you all but I don't spend a lot of time using the filesystem as such and any applications that read/write to it generally do enough processing so that the raw RW speed is of little importance anyhow.
I think we would gain a lot more from running real life testing on the various ROMs instead - such as batterylife, 3G/HSDPA handovers, signal strength, crashes/bugs (and yes, the 1922 bugs should be included) etc.
I would also like to see more of a variety between the ROMs. We only need so many releases where the base OS and Manila are exactly the same - I would prefer more UI customization, RemoteTracker implementation and so on.
Well to be honest I too miss benchmarks. And I dont really agree that benchmark doesnt reflect ROM speed. Because it really is faster in everyday use if the numbers are higher (and yes, you cant just look at total rating, but overall ratings invidualy. But thats my opinion
This is what happens when people become precious........the benchmark was nothing more than a handy guide, pity people couldnt control themselves and turned it into a competition.
I too miss benchmarks. I totaly disagree about the argument they don't reflect
real speed... Ever i use the top, i feel that is more fast. Stability is
another talking. It's a thing that you need to test yourself. We have a thread for people say their notes about stability.
People need understand each rom are focused in something... Some are in
beauty, some are in updated programs, some are in speed... etc etc...
Some cookiers try focus in speed, and when they can't be at first do an war against benchmarking. I hope their war against benchmarking does not start again.
the benchmarks were rigged. Good riddance.
so..... pietrucci
please consider to re-open your usfull thread...
Thank you for your hard work, everytime there were rom updated , with in a few days you always updated them ....

If you like it so much why don't you start a new thread and do it yourself?

I post where I want and I don't need you to tell me what to do. I made the statement because he said he was no longer going to do it. Everybody wants someone else to do the hard work. Also it was never my intention for the benchmarks to close so don't make such a stupid statement.
Not gonna comment about your position in Benchmark closing, but its totaly inappropriately for you to be commenting on this thread. Hower he liked benchmarking and we liked his benchmarking. This thread is like "thank you" and "we will miss you" to him and also "is there any1 who could do the same?" to others. And I wont make another comment here and totaly not gonna argue with you, but you should give it rest.

There is nothing to give it a rest about. If someone wants to do the benchmarks in a fair and controlled manor, then fine I commend anyone who can spare that much of their Time. Enough Said
Thanks you appreciate my work (at least most of you). Although it's a lot of work I always enjoyed benching new Roms. But at the end there was so much negativity and competition that it couldn't last any longer obviously so itje closed it down.
I still benhmark but don't publish anymore.
Hi pietrucci,
Dont know about others but i loved your benchmarking. I was admiring how you made all this work just for this comunity to have at least something to judge ROMs. It was great while it lasted.
Did i understand it right that you are continuing all the benchmarking statistic but doesnt publish becuase of negative comments of certain people? If so then now that makes this sad. If they thought benchmark was useless, then they just shouldnt read them. For us who was really interested in all these numbers it was great and we loved it.
Well now I feel better when i know that you are still continuing and you are not bothered by them. Thank you for all the hard work you have done till recently =)

[DISCUSSION] ANDROID/MAEMO/LINUX on HD2 (Discussion Thread)

Okay I'm a lurker on the developer thread and I thought it best to create a separate topic where everyone can talk about it (or complain that people can't shoehorn an OS on a device fast enough for their liking despite the fact that people are doing it for free basically) without all this "DEVELOPER DISCUSSION ONLY AUGUGHGH" "but we don't know where else to post about it"-ism
so this thread is for the non-developer discussion of said project:
http://forum.xda-developers.com/showthread.php?t=578575
(won't let me past "outside links"(?) cos I'm a n00b for some reason)
so there's no excuse now for anyone who posts "when is it done?" in the other thread
Also, a few pointers since some people don't get it and I'd rather save a developers/non-developers civil war thing.
How long will it take? - You're looking at about a year at least. Remember, it's installing an OS on a system that isn't meant to even have it. It's going to take a hell of a lot of time to guesswork and muck around with this stuff.
(all the people moaning on engadget re: the US HD2 launch being all "HTC release an android update right now " and then being all "OH XDA WILL SORT IT OUT" (because apparently xda is their overnight miracle machine) annoy me something chronic for this reason.)
remember too that these people are more or less doing this for free.
Can't you just install the Nexus/Supersonic/etc. rom on there? - No.
from what I understand of the whole thing (I'm not a developer so take this with a pinch of salt) there's an awful lot of different code and such on these things which means it isn't as easy to just "install" it on another OS. It's like asking why you just can't fit a jaguar engine into a VW beetle. It could work, but there'd be a lot of work and rerouting etc. to be made and even then it would need a lot of tuning and sorting out.
Is it ready yet? - No. You will know when it's ready.
What's happening at the moment? - From what I've read of the whole thing they're trying to iron out kinks with the linux Haret thing thats going to run Android. After they've got it to boot, they're going to have to try and get android working with the HD2. This is why it's taking so long.
so yeah.
hey??
yeah but..
this is the xda DEVELOPERS forum
and this is the HD2 DEVELOPEMENT section
so i guess the linux android development thread does what its supposed to !!
i know its frustrating and you like me want android on the hd2 but to be honest i i find half the fun is the bloody long wait and the small progressions that are made, thats how we learn.
=====PEACE=====
edit >> ok looks like this thread was useful after all - my wrong !! ..
**shrug**
A mod can move it elsewhere if needs be, I was just getting sick of all the feuding going on between people who wanted to talk about it and the developers yelling at the people who aren't posting about developing and thought it best to make a separate thread so non-developer people can talk about the project and developer people can drop in and give advice
yeah
actually you got a point.
theres a fair ammount of flame grill on the other thread that does get annoying
i subscribe to the other thread so i get an instant email for every post and i get my email on my hd2 just as you would a text message so it can be a pain.
=====PEACE=====
Ha finally found again this topic.
I am wishing you all my best to port Android to the HD2 because with all the **** around WinMo 7 comptability, you look the only one able to save the HD2 in the future!
I really hope everyday that Android will be working on our HD2...
Btw, the HTC Desire is going to be out soon, and it has the same specification than the HD2... Does it increase the chance got Android on our HD2?

Why don't *YOU* take the lead then if you're so capable of passing judgement on other people; as to do that you must have some amazing development skills in getting an operating system running on unknown poorly documented hardware.
Obvioiusly everyone will bow down to your uberleet level of skill when *YOU* present all of the fine work *YOU* have done!

why it's not possible to use NexusOne rom dump, and using it for HD2. Hardware is nearly same except buttons and screen size.

Ooooh dear...i´m still wondering why people are that damn lazy these days, not reading just one line in threads that are having 709 posts at this moment...don´t you people think that there should be a 100 percent-likelihood (in a developers-forum!) that another big brain spits out such ideas? exactly 1.000 other so called "newbies" have mentioned this point in the past few weeks...sometimes in every third post, again and again, without having read what other people have posted one line above. This is not about beeing a newbie or not, this is just about a little respect to the developers, serving nice presents to all of us without getting paid for it. what you guys can do for them? well, the first step should be not to spam around questions that already have been answered 1000 times before...instead go and read through the replies and at the end, when you are sure that there is no answer yet (after using the search function too, of course)...THAN ask your question or type in your comments and I think everbody will thank you for your participation in this community.
Sorry zabique, of course this is not against you ...but after reading exactly the same line for the 20st time/last two weeks there was no inhibition of my fingers typing these lines possible
i have a lot of respect for those developers, i die a bit inside every time a noob asks how it is going and **** like that.. anyway its nice they are working on it and i hope they succeed! dual boot windows / android would be really cool to have! i will surely donate if its working.. but to who should i donate? maybe its an idea to make a sort of bounty (lets say i will give $20 for getting android on hd2) and someone else also $20. thats 40 in total. if that 40 is shared and given to the developers that have worked on that project it would be a stimulation for them i guess.. only i dont know what developers are working intensively..
anyway my reward will be $20
more of you are going to join?
maybe its an idea to add the totall's of the $$ and the name who gives what in the first post?

actually he is quite right. if you have any idea what developers are talking about then you can see that all they do is guess in trial and error style. but aparently you dont have any idea
From the viewpoint of a software architect, it's indeed hard to watch the other thread without crinching every once in a while. On the other hand, the plan of attack there seems to be part of a culture that has done stuff like this quite succesfully with other challenges.
So i won't be surprised if we eventually get a nice port of android running on the HD2.
Mind you, i do believe that an undertaking like this would need the infrastructure, tools and mindset like the main android project has in place at the moment. But that would require a "DEVs and Testers only" door policy.
Simply put, the other thread here lets the lesser gods put their 2 cents in too. I'm cool with that.
BTW, i do not approve of any condescending remarks about the the other thread, nor do i wish to make my own through this mail.

[DEV HELP][?]Looking to Build a ROM!

well i thought i'd get this up before source for JB (4.1) drops... I'm looking for a dev willing to let me watch them as they build a ROM and make changes to that ROM... no i don't need to come over your house to do this... I was thinking of a live video stream of your screen as you do the work... if you're willing to allow me to watch and maybe answer a few questions in between, i'm willing to learn!!
i learn really fast if i'm watching someone do it which is why i'm taking this approach rather than trying to read through a bunch of threads on this topic... that stuff basically looks like a foreign language to me... especially when they talk linux stuff lol... i can catch on quickly but i need to SEE IT BEING DONE... not reading and having my brain decode what i just read...
so please pass this thread along... the site i'm looking to use is join.me and it can be viewed by more than one person... so if someone else is willing to jump in on the fun and the dev is cool with it... we all can watch as they work their magic...
preferably someone that's gonna be building on crespo/crespo4g... but i'll take whoever is willing to teach!!
disclaimer: i'm not even looking for a real "expert" on the subject... just someone to do the basic work so i can take notes and then do the stuff myself!!
PM me if you're a dev and willing to help out!! what do you have to lose? nothing really... you're just gonna load the program and let it stream as you do the stuff you normall would do...
sn: it doesn't have to be Jelly Bean... but seeing as source is coming out soon... i figured someone will want to start fresh and build from aosp... that's really where i'd like to start from!!
I'd love to watch too

I agree with the OP, one thing I think is missing (or at least in my experience hard to find) in the Android ROM community is a set of guides on how to properly do things (branch with repo to make a mod, apply patches from other trees, add prebuilt apks, add source provided apps, integrate su, busybox, creating your own vendor, device, adding your kernel, etc)
It's all scattered all over the net, sure you can figure some of it out but if you lower the barrier of entry people will be able to focus their energy on doing better work somewhere else.

i know Fergie usually puts out some great tutorials... i used his stuff when i was learning to theme... so hopefully he delivers on this as well... i would still like to do a live "webinar-type" of training tho if any dev is up for that!!
we can get a time going so that everyone can login at the same time and see what's being done...
I'd also like to see how its done, I would love to be able to cook up some things and then release a ROM to the public. I'm sure it's not easy but I'm willing to take a wack at it
Btw are you guys using pretty powerful computers for building ROMS? Or would you say they're average spec?

mine isn't that great tbh... but it manages to put out something... once your setup is correct and you do your first build... the second build of that ROM is usually a lot faster...
i think average would be around quad core with 8GB RAM... that's my guess based on a few devs i've heard from...

There should also be a thread for porting, kinda like "chef central" where users could get support on certain issues with their ports.. Over there in chef central the people seem to only help people that are building from source.. there's not too much support for people doing ports which is unfortunate because not everyone is skilled enough to build from source and having ports is what keeps some devices alive... In this thread there would be threads where you could post your logcat if your not getting boot and some of the more experienced porters (like fergie for example) could take a look and point you in the right direction. Also there could be guides and tutorials as how to get certain aspects of the ROM working like HWA, WiMax, MMS/SMS so on and so forth... I think that it would really bring a lot of new life to some devices that don't get the support that they should..
Anyone else agree on that or is just me?

I agree with the whole sentiment "more people should build things", but not with "aosp is too hard so we should help people do ports". Unless a port is the only way to get a device working, we definitely should focus on making aosp easier to learn if that's part of a problem the porting people are having.
Anyway, I started my own ROM yesterday and might end up making a wiki to document a bunch of things I'm doing. It's a very stock-ish ROM though, so I won't spend much time writing about adding mods other than a few basic ones.
-IF- I do get around to making the wiki, I will post here about it.
As for the computer, I am using a i7 930 (2.8GHz) with 24GB of RAM.

Well, one of the fun things about being a maintainer rather than a developer is that you really don't -need- much knowledge at all.
Everything helps, though. Yesterday I fixed a gcc compilation issue from knowledge of C++ that I acquired over a number of years. It wasn't a hard bug to fix and I could've asked a friend about it instead, but being a programmer lets me get away with fixing mistakes I see in AOSP when it's necessary (it rarely is).
Later, in my kernel compile, I turned on a compilation flag because I knew that a warning (that failed the build due to -Werror) was completely inaccurate. Good luck doing this if you don't know what's a compilation flag, and good luck doing it safely if you're not sure what the warning means and if it is really safe to override it (it often isn't).
If you want to make a ROM and be efficient about it, I think the two most important skills (in order of importance) are the ability to use git and to solve problems. Without a minimum of source control ease, it will be a pain in the ass to add features to your mods or to keep track of changes efficiently (especially when it comes the time to branch off releases and what not). Problem solving is what you do whenever stuff that should work doesn't work. And it's always hard because if it wasn't hard it would be documented already so you wouldn't have the problem.
If you want to build FEATURES for a mod (that is, not repack what others have written), then yes you will need programming knowledge. Java, C and probably C++. Mostly Java for user facing stuff.
great post gparent... that was a wonderful breakdown of how ROM making works... if it's all true (which it sounds like it), then this might be a bit more than i can chew lol... i'm still willing to see someone in action do these things so i have a better understanding of how to put things together and maybe one day i'll take a stab at building my own ROM!!

[MINI NOTES] MiniCM10 for Xperia x8

I have created this thread so that I can offer my thoughts on the MiniCM10 ROM for the Xperia x8. Think of this as a pre-review. If you have ANY suggestions, please leave them as a post below.
This is a pre-review of the first version of Mini-CM10 on top of the first version of the jb kernel. Both pieces were created by nobodyAtall.
I would prefer for people to see this as a MICRO review. The ROM is in a beta like state so there will be very little for me to talk about.
If you have not read my review of the MiniCM9 ROM, see HERE​

Yes in deedii :laugh:
A full review will be typed up once MiniCM10 is finalized. Props again to nAa to another great release.
The latest and only version currently of the MiniCM10 ROM for the Xperia x8 16th of August 2012. After using the Mini CyanogenMOD ROM I can guarantee that this ROM has promises of greatness. Many ROM breaking issues however still exist: voice command, sign in issues and so on. I refuse to hammer on these because they will be ironed out later on. So without further or do I will review away on the three main areas.
Visuals
CyanogenMOD stays true to the original gangsta' version of Android. (The vanilla experience). Yet again the ROM continues to offer a beautifully tweaked to impress version of Jelly Bean. Unfortunately, as of now, new wallpapers are missing however I'm sure they will be added later.
Kernel/Performance
I have seen a great increase in overall performance from this ROM. I can safely say that you won't be stumped by 1-2 second delays like you were in CM9. The battery has also, from what I have seen so far, been moderately extended. Getting 4-5 days of moderate use.
Advanced Options & Apps
I have seen no big update in how many advance options are offered. Similarly no new apps have been added. Hopefully this will be changed in the final version. A suggestions would be to have two versions maybe, one with advanced options and one without. Maybe a port of these options from CM7 can be created.
Conclusion
MiniCyanogenMOD10 for the Xperia x8 shows definite signs of the ultimate ROM. I see no reason why the final verison should not be ROTY. (rom of the year). I have tried not to hammer on the bad because everything will be fixed as usual later on by the renowned developer nAa. Drop a thanks by his post if you have benefited from him.
RATING: I will not rate it in its current state. :fingers-crossed: This is out of pure respect for nAa
I have spent quite some time typing this review, please do not troll. All suggestions on the other hand are more than welcome. Please hit 'thanks' if you appreciate my massive effort. Sorry if this is not something you wanted. Even though the guide is long, I call it mini because it does not cover everything.

Great rom on limit hardware...
I just install SRS trumedia then delete dsp manager so I get more free ram.
Cause I can't install super charger and change Trebuchet with others launcher.Any Idea about it ??

Seeing as this is a review I cannot deem it appropriate to offer tips. Once the rom is finished however, this guide will be produced.
Thankyou again.
How far is this madness gonna go?!
I'd like to stress the fact that our X8 doesn't have what it takes to handle ICS/JB properly.
I appreciate your work, nAa, I tested MiniCM9 twice and I twice returned back to GB with the feeling of satisfaction.
These ROMs can serve as nice experiments, but are very unsuitable for daily use. You even had to expand the system storage at the expense of internal data, forcing others to use sd-ext, bringing potential new issues connected with that. It's obvious that you try to bring this to a usable state, but I doubt that's possible. Anyway, what's the point? GB can be modded to look like ICS and still work like a charm...

You got a point there. Then I guess it's better to stop working for these devices and let them die.
Development is about breaking the limits. If some of you isn't satisfied with ICS or other custom ROM, please flash Eclair or Donut and enjoy the ride

And that, my friends, is how soft modded roms are created.
Sorry to disappoint you with a somewhat bad review I understand all that you mentioned fully. I too can see the x8 becoming a legacy device in months to come. I myself think I should trade the Iphone 4s I got as a gift for an S3 because even though phones keep changing, I can see the s3 as a spectacular phone for years to come.
I will support the x8 community with reviews, tips and help until it dissapears. Thankyou for the comment.

NOOO, nAa, I don't want to disregard further development on X8. Maybe there's still something to be improved on GB and Froyo...
I tested your MiniCM9 for about a week and I only confirmed what I thought it would be like. Beautiful and attractive, if there is a reason for having it, then it's the look.
However, even though I used swap and a2sd, I still experienced that drawback in responsiveness and RAM management from previous android versions. I admire your persistence and effort. It's interesting watching how much can our X8 take...maybe JB is the end, who knows?

Sorry, but I know how ICS works on X8. Try installing 60 apps and use them fully for a week... It really is great and stable, but not suitable for with many apps

Yeah, I can't help myself. I have 5 dictionaries, 16 games, audio player, video player, browser, pocket, reference materials to school like periodic table, office, file explorer, xda,TB, reader, web storage apps,...
I always use my X8 like that. I restore it from TB
But with such a small amount as you use...I don't see a problem as using ICS as a daily ROM

Really don't appreciate that.
You can live in your imaginary world where the x8 is supported forever but we all know it will be abandoned sooner or later.
Also, with no ROMs of your own, guides of your own or support for the x8 community, statements like that will plunge you in very deep.
It's clear you didn't read my post.
XDA is based purely upon reading. If you struggle with that I suggest leaving. I myself speak 3 languages so don't even get me started on the difficulties articulation.
Thanks
thanks also to CtrlAltDeleteIrl.
Hey everyone, nAa thanks for such a great rom, and kernel work and keeping our x8's top notch
I actually wanted to share something with you guys, i've been testing on mini cm10 and managed to upgrade it successfully without formating data partition, and things work excellent.
As new to the forum i can not post into development threads so, here we go
A major downside to this version of jelly bean i think is the a2sd script, which i think is fine, at some extent(data fills up rapidly).
I rely most of time on link2sd app on gingerbread, but its not working in mini cm 10 (works but its buggy)
So i had to make room for my apps somehow (about 120+?), so i wrote a little experimental script based on a2sd, im rusty as it come to scripting but still gets the job done, i wanna somehow forward it to nAa, as i think it works good for my purpose which is:
Move/make symbolic links of:
(link2sd already does this, on mini cm10 is buggy)
data/app/*.apk -> sd-ext
dalvik/@[email protected]*.dex -> sd-ext
data/data/*/lib/*.so -> sd-ext
(this one free's up a lot of space on /data among with libs to sd-ext)
dalvik/@[email protected]*.dex -> sd-ext
(however if we mount bind with a2sd, whole /data/dalvik-cache, this is moved too and makes rom super slow)
dalvik/@[email protected]*.dex -> stays on internal
I ended up with almost a 50/50 ratio of free/used on /data (i just checked i have 153 apps on sd-ext and 3 on internal)
Also had to edit a2sd script so if flags are not set, it doesn't delete dalvik each time on boot, the only thing i don't seem to find how to do is, that this rom deletes the symbolink links of libs on each reboot(filling data partition again on start), maybe you can help out on this one, nAa if you are interesed i could send you the little script, I think you could arrange it to make mini cm 10 much better
keep the good work up!
cheers

[Q] Beta-testers needed.

Hi guys,
I am trying to develop ROMs for Android. And I have developed one. This ROM is based on the stock HTC One ROM. Getting straight to the point, I need some Beta-Testers as I don't have the device with me. Sure, I'm gonna buy it soon. But in the meantime, I don't want to waste my precious time. SO< ANYONE INTERESTED? :highfive:
Thanks in advance.
Blind builds like what you did are not encouraged because it magnifies the chances of things to go wrong since you can't test the ROM yourself. Just a not of caution

yea. I know it is a blind build, but I didn't really do any huge modifications. Just some changes here and there. I have the build ready with me. I just need a guy to tell me surely that this build is safe to work upon further. That's because I am gonna resort to android development in future.
Short of sounding like a D-bag, what you're asking for is a little ridiculous. You sound like you're new to developing, new to the boards (Welcome btw) and don't have the device yourself. Its like asking a random person to test drive a car you just built by reading a "Build-it-yourself Car". If you had more credibility, i.e. More posts, past work, past examples of ROMs or even a list of what was "modified" in this ROM, people might step up to help.

I do agree you have to start somewhere. But he should get his own device and test it himself. That is better than just creating something that you don't even know it works.
Some "experienced" developers sometimes don't even own the device to create a custom ROM. But the key is that they are already experienced and would know how things work. But for someone who is starting out and have very little experience, they are better off doing the tesing themselves.
I bet he is not really a dev but more like a zip dev if you know what I mean.
OP.. please understand. Your new here, you have no proven track record, your asking people to entrust a €600 device to something that you have 1. not clearly laid out in your opening post 2. have no means to test yourself 3. can not provide support if you feck up other peoples devices.
Sorry but without any past experience here your trust level is 0.
Your request is akin to a nigerian ringing me and telling me I've won a multi-million € win and all they need is my bank account, and credit card info....
At least stick around here, get the device yourself, build up your reputation, and try a few things yourself and then clearly lay out what you have done in any further thread requesting testers because blind faith only goes so far......... unless you are indeed Jesus (or a nigerian with my mulit-million pound win)...
Wow.. so we can't waste his precious time. Lol

Hey hey hey! Please don't classify me as a ZIP dev..!
N yeah. Here's the change-log of my ROM(though it's not much):
1. Rooted
2. Busy-box added.
3. Changed the boot-animation a bit.
4. changed the power down animation a bit.
And' thats all.

I think everyone has to start somewhere, but I think the people are looking at stuff like what did you change in functionality not just cosmetics. Try playing around with build prop and stuff

Yeah, sure. I would work on this ROM further. But somebody has to test this adolescent ROM first, because it could happen that I work upon this ROM without testing it and then it would happen that it won't work. And then I could have to roll-back, only to start from scratch.
And that is why I'm asking you guys to test this out. I guarantee regular updates, fixes, etc.
