I'm on CM12.1/0801, i tried this and i still got philz :( thank you though, can you give me a link for flashing the original FOTA Kernel?
[Xperia SP Original Android Development] pilger:
The link for the FOTA Kernel is on the first post of this thread. Notice that you'll have to do it with Flashtool on your PC.

Before flashing the FOTA, have you rooted your phone? Did you try the manual command I suggested on the other thread?
[Xperia SP Original Android Development] J73:
okay i'll look into it. Yes I'm rooted and yes i tried flashing twrp 2.8.7.0 via rashr. still no good.
[Xperia SP Original Android Development] pilger:
Rashr didn't work for me as well. I had to do this: http://xdaforums.com/showpost.php?p=62101483&postcount=5 . Maybe it helps!

Beware of this before flashing the FOTA Kernel: it "unlocks" your recovery. This means that you'll be left with whatever recovery is flashed last on your device. For example, if you flash CM, you'll have the default Cyanogen Recovery. And the default Cyanogen Recovery can't flash most of the things out there. Then you'll have to use Flashtools to flash tangerine or another recovery into it. It's a bit of a pain. That's why I opted to keep my FOTA locked with TWRP. It's stuck on my device the same way Philz is stuck in yours right now.
[Xperia SP Original Android Development] J73:
if i do this it'll `unlock` my recovery right? can you tell me step by step? first i'll do this, then whats next? can i lock it again with twrp installed? really appreciate it thanks!

!EDIT: I did this and I have twrp now! thank you so much! now how can I lock twrp to my recovery?
[Xperia SP Original Android Development] pilger:
Sure. But first, what is the end up result you're expecting from all of this?

Do you want to have just TWRP or both TWRP and Philz at the same time?
[Xperia SP Original Android Development] J73:
TWRP is enough.
[Xperia SP Original Android Development] pilger:
Let's move this to the TWRP thread then, shall we?

Sound Settings

In sound settings, the Headphone Gain always set on level 7, and Speaker Gains set on level 4. No matter how many times i changed to other value, always get back to level 7 when i connect my headphones, or level 4 when reproduce any sound on speakers.

I have this problem in every version of tangerine Kernel. Im using AICP 10 Rom.( [MENTION=5727088]Tomoms[/MENTION] )

Any idea of a solution??
[Xperia SP Original Android Development] Tomoms:
When you have already started playign sound, move the gain bar using the + and - buttons placed on right and left. BTW, I might find a workaround for this bug soon.
[Xperia SP Original Android Development] NotAbdShahid:
I don't really know what the bug is actually tbh. I know it always stays on 7 but even on stock kernel, the loudest volume gives the same sound that it does when there's no faux sound i.e on stock kernel. So despite it being on 7, the volume I get is the same that i would get on stock kernel i.e no gain at all.
[Xperia SP Original Android Development] fefepato:
Thanks for the reply. I've tried that before, and it works but only for the moment. When I stop the music, the headphones get disconnected and reconnected, the gain is again at level 7. :(

I hope the solution that you speak of, will be soon available. :D

Thanks buddy
[Xperia SP Original Android Development] Tomoms:
It's a fake 7, actually it should be 0.
[Xperia SP Original Android Development] NotAbdShahid:
So the bug isn't that it blasts the audio really loudly, it's that it's displayed wrong?
[Xperia SP Original Android Development] fefepato:
In my phone there is true Gain. For example in speakers, sound begins saturated when the volume is above 70%, and sounds really bad.
[Xperia SP Original Android Development] NotAbdShahid:
I've not tested the speakers. Have you tried putting it on full volume with stock kernel?
[Xperia SP Original Android Development] Tomoms:
Exactly.
[Xperia SP Original Android Development] fefepato:
I just did the test now, and the sound is good. None of the speakers saturation. So definitely in my case there is real Gain, in speakers and headphones.

By recommendation of [MENTION=5651106]flash-[/MENTION] last week i returned to 4.3 Stock ROM from Sony, flashing the FTF hoping that will reset all. But the problem persists after that.
[Xperia SP Original Android Development] Marco20:

AICP 10 30/07 NIGHTLY with TANGERINE 7.0 beta 2

Sound gain it REALLY WORKS for me. I had to set headphone gain to 4, instead of default 7, which is clipping, but the thing is the feature works on my device.

The battery consumption is way better than default AICP kernel, almost as good as stock Sony.The only problem I have - somethimes the phone lags when I try to wake it up (receiving call, wanting to take a picture etc), it refuse to wake up or didn't respond to commands for about 10 sec.
[Xperia SP Original Android Development] moozer:
Tomoms - any intention to increase the amount of governors for XenonHD? Not feeling the love from Tangerine+XenonHD at the moment with the limited governor base.
[Xperia SP Original Android Development] Tomoms:
That will be the goal for v7.2. BTW, v7.1 will be released later or tomorrow.
[Xperia SP Original Android Development] Furrydaus:
Just do you know, its a kernel adiutor bug

---------- Post added at 09:03 PM ---------- Previous post was at 09:00 PM ----------

Many kernel developers have shown that more governors doesn't equate to better experiences. Instead, a better OnDemand Governer that is tweaked based on the device is all that is required to gain good battery life and performance. Only required governess are PowerSave, On demand and Performance.

Please [MENTION=5727088]Tomoms[/MENTION] I suggest that you stop bloating the kernel further. Instead, choose to go through the more efficient and best route, work on the On demand governed or the SmartAssV2 governer
[Xperia SP Original Android Development] Tomoms:
Ok, but please remember that while most of the devs on XDA (you are included) are geniuses, I'm a complete noob that doesn't know how to program.
[Xperia SP Original Android Development] Furrydaus:
You can always look at other kernels that follow the same route at Xperia Z's Zombie Kernel. Its a prime example and you should look at the commits and try to make sense out of em. Anyways, kernel creation needs programming skills so start brushing em up :)
[Xperia SP Original Android Development] Tomoms:
I wish I had time to learn a bit of programming, but as soon as school starts I'll be super busy ;)

Anyway thank you for the suggestion, I'll look at that kernel soon.

[Xperia SP Original Android Development] TechnoSparks:
It would be great if you keep the "conservative" governor. The settings posted in AICP's thread just work very well to me and I extremely like how my device cools down under his settings. I can't find any other combinations that could perform well on my device other than that one. :)

Hey guys, I'm looking for undervolting. Is there anyone that undervolted the CPU? I don't know the right values to change...
[Xperia SP Original Android Development] Tomoms:
In Kernel Adiutor set the general offset to -20, then immediately restore the original values of the 1800 and 1900 MHz frequency.

[Xperia SP Original Android Development] Phantom2332:
The last update is amazing thank you Tomoms ;D
[Xperia SP Original Android Development] pec0ra:
I agree with that !

After taking some classes about computer architecture, system programming and operating systems during the last two semesters, I'm just less confident in what new governors or scheduled can do.

CPU performance is so complex that to understand what could enhance the performance/battery ratio, you would need some really deep knowledge of the CPU architecture (and functioning of the OS and many other thing). Or some really good testing but doing it in real life condition is really difficult.

The performance and battery are influenced (in the CPU) by :

- how fast the CPU runs

- how much the CPU consumes at each frequency

- how much more the CPU consumes for each online core

- how much longer the core will take before to go offline if its frequency is decreased

- the ratio operation per second (frequency) / power consumption of the frequency

- the overhead of calculating what frequency to choose

- the overhead of plugging in or out a core ( you must reschedule all the tasks )

And many more ! These aren't even all dependent on the governor but also on the CPU hotplug. So you never know when you change one of them how the other will react.

Everyone can have an idea the kind of effect each of these previous points can have on CPU performance or power consumption, but getting something good out of them is really complicated. The people who can best adapt the algorithms or parameters are Qualcomm or Sony's engineers who know a lot more than we do about our chip.

Now don't get me wrong, I'm not telling the work of the xda devs is worthless. A lot of developers on xda have great knowledge and can probably manage all of this. I'm sure some of them can even do a better work than Sony (they have no budget nor (or less ;) )unhappy customers) but governors like ondemand have been worked on by a lot of people during a lot of time and are a really good base to work on.

Now even if a great developers create a great governor, it will probably not be optimal for our device without a lot of tweaking.

So you'd better off stopping using some exotic governor and start using ondemand or interactive... Unless you just want to try new crazy things on your phone... wait... What did I just say ? ! Oh damn ! I forgot we are all on xda for this ;)

Just check the governors in the Kernel Audiuter. If you see a governor called Lionheart, then you have 6.6, if not then you have 7.1.

Again, this is the exact reason that you NEED to stop replacing Ramdisks. Use the AnyKernel feature to make sure things don't get screwed over for multiple roms. The more you delay, more people will sadly leave.

In cm 12.1 v6.6 works perfect . no yellow screen , freezes or ... Just screen flickering like other ubls.

But in v7.1 no sim detection and i need my sim working so i cant use or test it. But i like kernel linux updated :(

Plz continue your great work .
[Xperia SP Original Android Development] slim_guy:
I did some benchmarks by using different io schedulers and read ahead buffer , i found that on internal storage 384 gives better performance than 128 and 384 is slightly better than 256,for schedulers sioplus ,fiops,deadline gave nearly same performance. I'm using f2fs though so your speed may vary.

[Xperia SP Original Android Development] pilger:
I'm getting phone restarts when turning screen on right after screen timeout. For example, when I'm reading something and the screen turns off by itself, then I press the power button real quick to turn it back on and the screen stays off for a couple of seconds, then the phone reboots by itself.

I'm on CM 12.1 Unofficial from July 26th and Tangerine 7.1
[Xperia SP Original Android Development] RandomUser017:
What about Tangerine 3.x, 4.x and 5.x?

And I also get screen freezing. But that's all.
[Xperia SP Original Android Development] Tomoms:
I don't get freezing. But maybe I know what's causing it.

However, I'm woring on AnyKernel2. It seems quite confusing, but with the help of some experts I'll learn how to use it and then... fare thee well, ROM-related issues!
[Xperia SP Original Android Development] RandomUser017:
I do not get freezing with 6.6, but with 7.1. As we know Xperia SPs can be different. I think this is an issue for some Xperia SPs. It would be great if you find out the issue. Would a KSMG be good?

Tangerine 7.1 for xenonhd is excellent but there is a little bug on GPU Ondemand Governor:

When I set the max speed gpu at 400 mhz, Kernel auditor sets 320 mhz :(

I have used also trickstermod and fauxkernel but i have the same problem, at the end i have set 400 mhz with performance governor, but i have more battery drain.

governor ondemandplus 1.7 ghz uv -25 mv (reboot during antutu benchmark, very fluid gaming experience)

governor ondemandplus 1.7 ghz no uv (no reboot during antutu benchmark, very fluid gaming experience) :)

In my case the reboot or yellow screen is present only with uv + ondemandplus governor

Ps. no problem in gpu ondemand governor, 400 mhz speed during gaming session and max 320 mhz during general use is a very good
