I use marsapa kk v4, no problem with tb.

It seems to be a smooth rom, i Installed it yesterday so i havn't tried it for long. Gb kk doesn't work all functions yet but apart from that it works fine i think.

I do not have SDFix, and the system platform.xml is untouched. What is strange is that by switching supersu applications (SuperSU or Kinguser), Titanium backup hang or not regardless the fact that is has acquired root access. By the way, for me root access means permission to read/write anywhere, isn't right? The Titanium backup hang problem is not understandable for me.

Caivs_ZP998.apk

What is Caivs_ZP998.apk in the System/app folder in the official KitKat ROM?

Maybe a virus/SMS malware?
[Upgrading, Modifying and Unlocking] AP756:
dnlilas, let me make an example. The situation is similar to using SDcards in a KitKat system. Yes, SuperSU allows you to jump into the pool, but Google (the operating system) does not allow that. They removed the pool... :cowboy: Well, having said that please read here that Google changed their policy to use external memory (they say safety reason): http://www.xda-developers.com/android/fix-your-sdcard-issue-on-kitkat/

If a program which worked on Jelly Bean does not work on KitKat the reason might be the policy of Google. To check that install SDFix and run it. If Titanium (or other programs) run after that your problem is fixed. If not I recommend to flash a ROM which is capable to run Titanium. Currently I installed Kkartanesi V2 (can be found on needrom), Titanium and Xposed both work for me. HTH

[Upgrading, Modifying and Unlocking] franny23dmt:
I have heard one good report on Kitkat. Think i might skip it. The antutu rating they advertise KK on zp998 is what JB achieves easily.

Ive only got one word as far as ROMs go "MIUI".

.

The audio thing, i just wanted to show how grossly inaccurate the "russian" person was that produced that odd looking spectrograph.

Ive worked in the audio industry for the past 20 years approx (producing/publishing). I didnt notice the output to be annoying when using bud ear phones (its just my phone for out'n'about music, not my studio hehe) , this is after equing the output with a decent multiband eq (poweramp).... then i got these bluetooth which cover the ears fully, so i am sure my POV is fairly skewed/bias. Either which way, the spectrum output still follows the classic shape/form of professionally mastered rock/ heavy metal / psytrance, which i found amusing considering that other graph. I think much of the whingers have been using the zopo earbuds that come with the phone, which are admittedly one of the worst sets ive ever tried ...even worse than $1.99 ones from 10 years ago ... i guess they got a bargain they couldn't refuse .... absolutely atrocious decision by zopo ... its like embedding a bouquet of roses with dog turds before giving it to ones wife .... .

.

I highly recommend the MIUI rom on needrom that was posted last night .... ive got Xposed framework running, its performing really well ... an interesting observation is that on the MIUI the antutu score achieves less, yet the use of it is way better performance , almost like the stock android knows its being rated & fakes its output . Stock rom is trash in comparison, & the TWERP recovery that is recomended with it is not at all buggy/corrupted like the demezza twrp for zp980 (which destroyed its telephony capabilities when it totally corrupted, thus making a wifi mini tablet out of it )

[Upgrading, Modifying and Unlocking] Anonyneko:
As far as I understand if you're using bluetooth headphones you're bypassing the built-in DAC altogether and thus you're getting decent audio, as much as bluetooth audio allows. The discussion is about the built-in DAC which is outright horrible, especially at higher volume. This is noticeable in any wired headphones, not just stock earbuds (that are indeed horrible in most, if not all, chinese and even some well-known brand phones). The worst thing is the crackling that is just super annoying at high volume.

So far the only firmware that deals with the crackling (with a slight loss of volume, but nothing criminal) is indeed MIUI (I'm using drezkod's builds from 4pda.ru), but even then the DAC can only produce something that doesn't sound like garbage after tweaking the equalizer, personally I'm using Viper. Still not ideal, but tolerable. I wish I could connect an external DAC, but I'm not sure I can get it to work.

MIUI definitely does not run as smooth as stock/modified stock, but it's fairly swift and stable except for the crashing settings. I'm not a big fan of it, but after some customization it's all right. I wouldn't be surprised if the stock antutu score is indeed fake, but that doesn't really detriment the experience in any firmware, the phone does have good performance in general.
[Upgrading, Modifying and Unlocking] noflip:
Oh man.. like I don't have enough stuff to do.I am actually getting tired of people saying that there is nothing wrong with this phone and I am hearing it wrong. I produce music. It is my job to be able to hear when there is something wrong with my sound.

This test was performed literally 4 minutes ago. The first screenshot is the output from a song, which was played on my PC. The second is the same audio file, played on the phone with the stock player, no effects or EQ changes. The audio was rooted through the Line In input of my sound card (M-Audio 2496) This is how the phone sounds when listening to music using headphones.

[Upgrading, Modifying and Unlocking] noflip:
so?

anyone has any idea what needs to be done, in order to improve the situation?

VIper helps just a little, you cannot eq your way out of a bad sound, this needs to be improved from within the ROM or the firmware.
[Upgrading, Modifying and Unlocking] Zyla:
Am I the only one, who has problem making screenshots? I have tried the long press of the volume down + power button, but it doesn't work.:(
[Upgrading, Modifying and Unlocking] lasslax:
Unfortunately there is no help, since it is a hardware problem, just like the GPS.

The DAC is a crappy cheap solution, optimized for phone calls with a bandwith 1kHz - 4kHz.

Using Bluetooth headphones you don´t go through the DAC, that´s why the sound quality does not suffer from it. This is a construction fail.

If you widen the bandwith by an equalizer, you amplify the noise also, so that can´t help.

It´s like using more deodorant instead of a good shower. Just supressing the problem, not solving it.

My advise (who needs advise? the wise does not need it, the fool does not listen):

accept the phones shortcomings for the relatively low price, or buy an S5 or a Note 3.

(I did the last one, and I´m happy with the Note)

Anybody knows how to change the color of status bar icons and remove de 3g indicator, in KK stock rom? I like the white color for every icon, like in aosp rom, but I don't know if it is possible to install some zip file from recovery to fix it.

[Upgrading, Modifying and Unlocking] noflip:
Now see, this is simply not true. This is one of the most widely spread DAC for smart phones, Yes, it is not the best quality and it cannot produce audiophile results in terms of dynamics, but there is a standard for frequency response and resolution and it is 20 hz - 20000 hz flat response at 44.1 khz resolution. Even the cheapest audio chips follow this in order to be classified as such. Again, a lot of phones use this very chip and they do not sound as bad as this

Additionally, ALL sound goes through the DAC, radio and bluetooth included. The DAC is what converts 0 and 1 into audio.

The problem here is that there is a preset, which is meant for the speaker, but it is rooted through the headphones by mistake and this can be fixed by ZOPO, as they have the source code.
[Upgrading, Modifying and Unlocking] lasslax:
1. The sound for Bluetooth is NOT converted to first analog and then to digital again for the Bluetooth and to analog again in the headphone. It´s nonsense.

2. The claim above makes me a bit cynical about your competense in this question. But giving the benefit of doubt, can you please name the DAC used in the Zopo? I could not find it out on my own, did not find any information just some assuming from others guessings.

Since I made a very primitiv amplitud measuring of the frequencies 800Hz, 1kHz, 2kHz 5kHz, 10kHz on the headphone output, I concluded my claim, that the DAC is optimized for talk, not for music. As I guess, the analog output consists a highpass cicrcuit at 1 kHz and a lowpass at 4kHz, limiting the sounds bandwith between these values. This is the normal case to the internal speaker, but the headphones output should be tapped before this circuit and go through a separate amplifier.

Please point it out if I´m wrong, but please not with just claims that "other phones uses the same", since it is not controllable, but rather with controllable facts.

Untill that I withstand my opinion.
