Personally, I'd say his his recent AEX. I never found Resurrection Remix to give me good battery life, at the expense of wonderful features. AEX balances features with great battery perfectly for me.

I will try it, dank je wel.

But it is my wifey's phone.

She is getting pissed now.

So i am going to downgrade it to AEX 4.6.

For that i need to downgrade the TWRP and the bootstack too right?

Her TWRP is v. 3.2.1.-0 and her bootstack is B32.

Which versions of both do you recommend?

Thanks!:good:

•Flash AEX.

•Flash MissValeria's Uninstaller just incase.

•Flash Wonder Wicked Witch's Viper zip (same person, she rocks)

•Start ROM. Don't play any music yet.

•Set Location to On (important*)

•Open Viper4Android FX.

•Go to Viper Settings.

•Lock effect mode to: Headset (this will be your default for speakers and headset)

•Don't play any music yet. Trust.

•Set Viper-DDC to Audiotechnica ATH-SJ55

•Set Dynamic Earphone to Monster Earphone - 25-30%

•Spectrum Extension 35%

•Viper Clarity 3.5db

•Make sure these are On except Master Switch.

•Play music with some kick to it. Unless you already have, you cheat.

•Turn on the Master Switch.

You doing this on your V20 or axon 7?
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Krystalmyth:
Axon 7 of course. :p For headphones you might want to switch Dynamic Bass to Unknown IV. Depending on your cans of course. I've done AB tests with everything in DDC. I know its not meant for this purpose, but it modifies sound so dramatically I had a test and SJ55 will awaken your sound on almost any setup. There are some DDC that get close. Phiaton MS-500 Sounds great, Jays V-Jay, Phillips Fidelio M1, Sony BT101 and a few others. Took awhile listening to these. The ATH-SJ55 I always go back to.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] SaintZ93:
Its something new to try and like AEX very much. The Emotion ROM is not active so I don't really maintain it anymore. I'm more focused on kernels instead of ROMs now.

You might want to flash this, you might then pick the right model (pay attention), it may also be possible that you'll flash the ROM afterward. I'm sorry, I wish I could help, but there's nothing else I can do for you. Good luck.

Damn, the driver didn't work, but with that config in the app and the magisk module driver this is really something.

Thankq

---------- Post added at 02:12 AM ---------- Previous post was at 01:46 AM ----------

On that note though damn the RR Oreo ROM is unstable. I mean I love it all, Oreo and Resurrection Remix is a beautiful combo. Bbbbut I also need a phone that works :(

Can anyone recommend a RR like rom that's stable and gets updated? Not even official RR Nougat has been updated for almost 3 months now :((
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Krystalmyth:
How do you conform if it's working or not outside of ears alone? I don't want to go insane doing an ear check like I did on the HTC 10. Lol I never installed a mixer or anything. The viperdriver activates for me of thats what you meant.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Spooderman46:
The actual driver wouldn't install after flashing the Wonder Wicked Viper zip, but the Viper4Android app that it installs works fine with the magisk module driver.

So no I'm not just relying on my acute sense of hearing ;)
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Krystalmyth:
Ah cool yeah if that's what you meant yeah its kind of hard not to notice anyway haha. Strange it wouldn't install. I always find it interesting even with the same device and ROM how little issues can separate them. Must be a nightmare for coders lol. I do use SuperSU so that could be the difference. I don't care about safetynet. Oldschool SuperSU up up and away anyday.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
Okay I already asked but XDA didn't seem to want to post what i wrote. What's the difference between using this V4A mod and just a normal V4A from Magisk f.e.?

Also, why do you recommend those exact settings? I've been using DDC like this for a long time, but usually the preset that YOU like will be utter crap for mine. I'm guessing you know what they do. You can go around testing them until you find one that you like, that is what i do. But using the same profile on other headphone will usually yield bad results. Example:

The HD380 Pro has a rather flat input response. My headphones are HD 360 Pro's (which without delving into it, they are basically spare PX360 parts but with hd380pro drivers). Because of the shape of the 'phones they have a rather noticeable resonance spike at 2kHz. So much that you have to lower it about 4 or 5 dB. I use a DDC profile that fixes my low-mid freqs, which is the Samsung EP-1.

I have also used a friend's M30X's with the same setting. They sounded horrible with it. I had to change the settings completely. They had a vacuum at 5kHz. literal vacuum.

basically what i want to say with this is, you didn t really account for all that, did you.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Krystalmyth:
Traditionally if you have certain headphones with certain requirements, you'd have to make adjustments. I have ATH-M50s and they sound like ass if I use its settings. Mostly my settings were for speaker users, and to introduce the concept of using DDC and headphone configs for tweaking as a lot of people leave it on speaker and use a convolver or something. If you've specific headphone needs, I suppose this is why there's over 100 different ones to choose from.

So no I didn't account for all of them. Ironically the HD380s DDC also sound great on my M50xs. It's one of the good ones.

I'm not using any scientific methodology with my settings, just what sounds good. This is sound, its more art than science to me. This is why I keep a fire extinguisher near when I listen to music at all times.

You going by ear to measure all this or what do you use? My mutant powers don't always cooperate these days, since the eclipse and all. Long story.
[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] Choose an username...:
Lol. actually i got the 2kHz spike by ear, then searched for the input response graph in google. There was maybe one graph made for the hd 360 pro's, but they reflected exactly what I felt was wrong with them.

With the M30X's I sorta cheated, I knew already but still after trying them it was overly evident.

Search for 'm30x input response' on google images for example, and you'll find the charts. they use a specially modeled foam head thingy with realistic ear canals, because those are the culprits of those midrange spikes (usually headphones actually have lowered mid-highs to avoid those spikes).

Again, I also use DDC's randomly. Neither the PXC360 (same but with other driver and Bluetooth) or the HD380 pro sound good on my 'phones. Just wanted to know if there was any difference.

p.s. after a bunch of testing with Dolby Atmos I sorta started liking it as a secondary equalizer. I usually like higher 250-500 Hz freqs, and Atmos with everything off and static equalizer is very good to, for example, boost the highs and those frequencies. it adds a boatload of noise though

Well,after i flashed AEX and mini gapps,i went to recover and flashed first Viper Wonder wicked etc and after Wonder beats.When i reboot i've tried to install busybox but i wouldn't because theren't any root or at least it was what it eas written in the notification.Again at recovery to flash supersu v.2.82.So when i boot up,i've open developer mode and press the permissive.So after all those everything worked fine.But if i flash Dolby Atmos from Oreo .zip,i get bootloop.

First of all: many thanks to Nfound for his incredible software, kranoner for his hell of a kernel and miustone for his beautiful snappatch!

I followed the instructions of krystalmyth (big thanks to you as well) for the best possible sound. I got everything working so far, here is exactly what I did to get everything working:

1. wipe data, system, cache and dalvik

2. Install latest aex (folks are right, far more stable then rr with the same amount of essential features [CRT Animation, flashlight on power button, weather etc.]

3. install latest opengapps 8.1/64arm (they're official now)

4. Install latest hell's gate kernel

4.1 reboot recovery

5. Install Snappatch, just do buildprop and sound fixes, make sure to un-tick optimized gapps

5.1 reboot recovery

6. Install latest SuperSU

7. Install ViPER4Android_2.5.0.4_Wonder_Wicked_Witch_12-Jan-2018.zip and WICKED BEATS [Viper+SonyBeats+htcBeats+lg]without dolby atoms [Target android Oreo]-wicked witch - 11-Jan-2018.zip

7.1 don't panic with second zip (wicked beats) taking a long time to flash.

8. Profit! Set up device, download some nice piece of music. Go into viper and follow krystalmyth's instructions. Everything should work fine. Only thing worth mentioning: starting up your phone will always result in a system message telling you that your phone isn't working properly internally (something like that). But you can dismiss that, ain't anything to worry about.

Hope I could help someone getting the viper install driver bugg :fingers-crossed:

Since this seems to be a dual thread, anyone try both AEX and RR? Seems like a lot of people like AEX better, but I tried it way back in the day and it didn't function well. I imagine it's a lot better on Oreo.

[ZTE Axon 7 ROMs, Kernels, Recoveries, & Other Deve] christoophat:
Thanks, that is promising, although different cars/car BT/phones give different results. Will stick with this N build for a while longer, then maybe dip my foot in O. I know O adds more BT control under Developer options, but at least on my LG G3, only the oldest one would allow playback thru to car BT, but without song IDs changing from the first played tune forward (would stick on the fist played infos). The others wouldn't even allow playback to car BT.
