Very strange, tried everything but still didn't work.. I'll try with another kernel when I get back home. Thanks anyway

Yeah ICJ, but I've had better experiences with OTG on Sense, had a lot of reboots using AOSP but last few kernel builds it's working great :good:

maybe a problem with ViperX 3.4.2? anyone confirm a working OTG with ViperX 3.4.2 and Xmister Kernel?

But it seems work best with stock kernel :eek:

Try with a modded kernel and after that with stock, you'll see the difference

Edit: more than this? Have to wait the bricked kernel + his own hotplug logic, sp, there will be more parameters to tweak, so, it will be possible to fix some other hight battery drains

is this Kernel more battery friendly than Stock if we flash it as it is? without messing around with parameters?

stupid question of branch 88:

Replaced stock hotplug algorithm with MPDECISION. (Thx to showp1984 for the code).

MPDECISION is a file script writed for qualcom's architecture, it's the governor of qualcom's hotplugghing, it stores in /system/bin/mpdecision/ , don't understand if you are meaning the "show-p" hotplug or the real MPDECISION :p

When we tweak on demand the values still recent after screen off (sampling_down factor, sampling rate etc)

Hopefully you can fix it
[HTC One X] drivenby:
Re: [KERNEL][#88][15/02/13][3.1.10][AOSP & SENSE][HardCap][S2W][GPU@520][UV]XM-Kernel

My values for on demand do stick.

But I think there's something off with the kernel. Performance should definitely be higher. And I'm not talking about governor settings, even with game booster on ultra settings (which set gov to performance among other things) my benches are too low for a sense rom.

Now I'm not saying I Care about benchmarks, but it is known sense rom (viper x) always score high on them because of a tweak that HTC included to allocate all processing power to the benchmark.

On games this is even more evident since interactive+gpu520 should play beach Buggy blitz more smoothly than what I'm playing it like atm, from my experience.

Other than that running smoothly so far.
[HTC One X] CamoGeko:
Have you thought that its all because ViperX is a massively bloated Sense ROM? 650mb and you expect everything to run smoothly?

Are you guys change the battery by yourselves? Can I know where can I get the battery from? Thanks a lot
[HTC One X] Tabtoub:
from ebay, google it u'll find it easily, and then follow the guides how to change it, it's quite simple, I opened my HOX last week to fix the wifi antenna problem, it took me 3 minutes to open and 1 minute to close it
[HTC One X] guiltyundertaker:
Damn. And I haven't bothered sending mine back for over a year because I didn't wanna be without it for 2 weeks. 5 minute job, really? I know what my mission is tomorrow!
[HTC One X] Tabtoub:
just be careful when inserting the pieces of plastic to get it out from the sides, to not damage any pins (I damaged NFC pins but I don't care about NFC lol) even though you can solder them, be careful when opening it, but once opened, it's very very easy, put some foil paper under the metallic plate of the wifi to rise it a little bit so that the connection is made correctly, then be sure there is no dust in the camera lens, and close ur phone :)

Now I measure the wifi, and it's the same or better reception then my laptop that I bought this year :D

PS : on youtube you'll find many guides, there is a guide that tells you to solder 2 wires from wifi metallic plate to the pins, but I don't suggest it, just put the foil paper under the plate :)

Sorry for Off Topic

hi ,

i tried the kernel aosp with cm10 v1.3 , every think will and speed

when play games as contract kill for test heating . the device was heating and used 5% on 3 min of battery

on stock kernel not heating and battery down 1% on 3 min only

its cuz GPU OC to 520 ? or any think else

thanks for your work!

Wifi solution

It looks like kozmikkick may have found the solution to the Wifi issue in 3.18 base. It has recently gone into the KozmiKKernel

Would it be possible to pull this into XM kernel as well (unless of course it is already there!)
[HTC One X] treebill:
Re: [KERNEL][#274|188v4][16/03/13][3.18][AOSP & SENSE][S2W][GAMING][BATTERY][UV]XM-Ke

It maybe the gpu oc, but its not really an overclock at all the tegra 3 stock gpu clock is 520 HTC underclock it to 420(I think).

If you install trickster mod you can set the gpu from 416 - 720.

[HTC One X] treebill:
Re: [KERNEL][#274|188v4][16/03/13][3.18][AOSP & SENSE][S2W][GAMING][BATTERY][UV]XM-Ke

Navigate to /sys/class/leds/button-backlight in root explorer or es file manager (any file manager with root access)

Open auto_bln and change the number and save.

Default is 0
[HTC One X] Tabtoub:
Download Android terminal emulator from play store and enter the command in the first post!
[HTC One X] dsonex:
using something like es explorer (enable root access in settings) goto /etc/init.d and edit one of the scripts and add the command from the first post - this way the setting will stick after reboot - directly altering the file will be lost on reboot.

Repack is needed for aosp rom(liek Slim Bean)?

Thanks! Gonna get on the case and do that today.

Also, I've searched but can't find, can anyone tell me if it's PMC battery or PMCv7 Performance included in 188v4? Or should I jump to #274 for v7 performance?

Edit: I've done it, it took a little longer than you because I was so scared of damaging the phone, also I should have stuck tape over the power and volume buttons to stop them falling out. But holy crap is the wifi better now! The difference is at least 10 times better than it was, I can't believe I've put up with this for so long! Thanks for your advice...

peeps have answered this already but its probably worth mentioning that all the echo command does is print the argument you pass it, in this case a 1 or 0, the angled bracket '>' just redirects the output from the default command line to the file you specify. It achieves the exact same outcome as editing the file directly in an explorer type app.

[HTC One X] guiltyundertaker:
I would suggest a combination of these methods:

Firstly, tape your power button and volume rocker up so that they don't fall out, mine did and it took me a while to figure out which way round they went back in.

Take out your sim.

Prise the bottom off the rear cover, like in the first minute or so of this video: http://www.youtube.com/watch?v=_jZ-nelmWAI

Then, when you have some purchase, run a plectrum down both sides (I couldn't find a plectrum, so I used an old credit card, it was a little flimsy, but did the job, I wouldn't like to have used anything metal), like in the first minute of this video:

http://www.youtube.com/watch?v=PrArAes5liM

Then use the foil fix from this video, very simple and avoids any soldering and possible mishaps: http://www.youtube.com/watch?v=zbmGNL1dsf0

Then reverse the procedure.

I was very wary and scared of doing mine, and took me more like 15 minutes in all, but it turned out to be very easy in retrospect. My main problem was that I kept pushing the power button and turning the phone back on while trying to remove the case. Then the trickery with the buttons falling out. But, still, it was pretty easy.

Kozmi , neo , xmister work closely together by what we saw and they are quiet friendly to each other , I doubt Kozmi will mind if he apply he's findings , after all we're all in the same team here.

@ Xmister

Found a mini bug with 273/274 , probably the same for every kernel with bln. When I disable it and later on if I enable it screen is unresponsive after locking it and only way out is hard reboot. Tho I did also change Burton's brightness as well , anyway isn't major bug. I guess it can be ignored.

It is believed that higher values get higher benchmark scores but lower ones provides better ui performance. You may experiment with it

Not too sure on what it's for but I know that lower values give better UI responsiveness compared to higher values, that's why Xmister & N3o have started making 128kb the default read ahead value. The only thing larger values is better for is higher benchmark scores

Edit: @crescal beat me to it :p

Thanks to both. :)

Is there any impact to battery life?
