O sorry: I have also the USB y-cable, with external power supply, but nothing... :( need other? I need not for mount usb but for a dongle usb for drone telemetry... (working on nexus 7 stock), maybe I need a special kernel with driver compiled?

Edit: Ok with stickmount usb key work, but not my dongle for telemetry :( Any possibility without recompile a special kernel?
[Nexus 4 Android Development] k500zm:
Got USB OTG working - had to install supersu as the superuser on slimkat would not work with Chainfire's Stickmount. Stickmount does work for Nexus 4 - [dont know why he says it doesnt !]

Excellent stuff zaclimon - thanks again for this great kernel ;)
[Nexus 4 Android Development] kol1124:
Any news about next update ?
[Nexus 4 Android Development] atulclassic:
nexus 4 is not supported officially..which means chainfire won't answer queries for Nexus 4
[Nexus 4 Android Development] :
will be updated to Linux 3.4.108 ?
[Nexus 4 Android Development] zaclimon:
I'll feel like there will be an update when I feel there will be an update... -.- And the next build will probably have 3.4.108 as well.

Anyways, here's a test build in which I have removed some optimizations related to the filesystem. That said I have left the LMK related optimization from Motorola in case. If your device still has problems, perhaps the problems will come from there instead.

Please report if this problem is still present. :)
[Nexus 4 Android Development] :
Thank you very much for your answer.

I am very happy with your kernel - is very good :)

I wish you success in your work :) :good:

[Nexus 4 Android Development] ObihoernchenDE:
Mhh just had a random freeze with this version as well :(
[Nexus 4 Android Development] emanuele1986:
No freeze for me yet,but for example facebook crashed as the v6 normal. "Same symptoms", today i will stress the phone....
[Nexus 4 Android Development] zaclimon:
Hmm for the issue, here's another test kernel. I've kept the FS optimizations but I've removed the LMK optimization from Motorola.

If it still doesn't work, I will have to remove them in the next version. (Which would make it quite like V4)

Even though, I'll try some stuff that can even enhance the performance further. :)
[Nexus 4 Android Development] ObihoernchenDE:
Hi zaclimon thank you! Will try it.

Was able to reproduce a slow down/long freeze today with test 1 again. Just started a YouTube video.

Collected all logs. Maybe it's useful.
[Nexus 4 Android Development] emanuele1986:
I will try it. So yesterday apart one facebook crash, no other problems. I had the crash with many app opened. Today I try to recreate the situation
[Nexus 4 Android Development] Italico:
No problems whatsoever for me!

Thanks for your work, zaclimon!
[Nexus 4 Android Development] emanuele1986:

Short update: No issue with v6 Test 2 and CM so far for about 3 days :) looks really good!

Had a lot of slow downs with v6 and v6 Test 1 before.

@ all with Facebook app crashes: uninstall this app and use the browser version. Facebook app sucks way too much...
[Nexus 4 Android Development] emanuele1986:
You think? But with v6 normal i had phone freeze as well after that crash. Sometime i had to do a clean install becouse when the phone restart after cm logo the screen was black. No problem with hellscore or stock cm kernel

So in 3 days 1 facebook crash and 1 youtube video crash
[Nexus 4 Android Development] kol1124:
Now, I end BETA testing and install normal version and ot works, so I think that it was Beta version crash ...
[Nexus 4 Android Development] zaclimon:
Thanks guys for the feedback related to the test versions. It looks like there will be a goner starting from V7. I'll still continue to check if there are interesting stuff to add to enhance further the experience while using Quanta. :p
[Nexus 4 Android Development] emanuele1986:
under 3g I had 4-5 facebook crash in 2 hours. If is the app why with stock kernel cm or hells core, the app worked fine?
[Nexus 4 Android Development] yochananmarqos:
The issues myself & others have reported were not app crashes, first of all. The problem may be triggered by memory hungry apps like Chrome & Facebook perhaps, however the issue is the device gets laggy, then freezes, then eventually reboots. You're not describing the same symptoms. As franciscofranco would say, you're issue is in user space, not kernel related.
[Nexus 4 Android Development] emanuele1986:
Yes i had too, i had freeze, reboot, phone gets laggy, phone crash and i had to wipe and reinstall the ROM, but these with v6 normal and when i used facebook and hardly ever you tube. With v6 test only facebook crash no freeze or others things.
[Nexus 4 Android Development] emanuele1986:
Another crash, this time with camera app and phone freeze and reboot :/
[Nexus 4 Android Development] ObihoernchenDE:
Still not a single issue since test 2 :)

Please don't use Facebook for testing this app is a nightmare...
[Nexus 4 Android Development] zaclimon:
I almost want to say that your device is beginning to show it's age, but I want to know if this issue only happens with this specific configuration or have you tried another rom perhaps?

[Nexus 4 Android Development] emanuele1986:
Only with cyanogen with your kernel. If i leave stock cm kernel or put hells core no problem o_O
[Nexus 4 Android Development] zaclimon:
What happens if you decide to start over with a clean flash?

Also guys, in lack of features to add, I've been thinking to add the hellsCode's patch into Quanta made by [MENTION=5222551]Maxr1998[/MENTION]. What do you guys think of it?

Max, as I see, one needs Xposed so that it can unlock the lockscreen when the code is right. Would backporting the Xposed feature into AOSP hard? Even if I don't have a lot of experience in Java, I could try to help. :p
[Nexus 4 Android Development] emanuele1986:
With a clean install i have the same problems with tour kernel . Maybe for a few days i don't have problems but after appear this blocks/freeze/reboot.
[Nexus 4 Android Development] Maxr1998:
Shouldn't be too hard - the main problem would be getting the saved password from config app. I will write an additional integration API for hellsCode to be added to roms, but at the moment, I'm focused on MaxLock. However I should have the needed time this weekend. ;)
[Nexus 4 Android Development] zaclimon:
Ahh I was pretty sure that the hellscode sysfs entry was the pattern saved into the file and hellscodeenabled one was the trigger for it to be enabled?

[Nexus 4 Android Development] dragos281993:
[MENTION=4217103]zaclimon[/MENTION] , I don't mean to be rude or ask something that you don't want to do, or tell how to build your own stuff, but I only have a simple suggestion. But first things first. The only "almost stable" CPU governor , at least for me, is "conservative" with some frequency tweaks, otherwise everything would be laggy everywhere and still there's plenty of lag here and there. With performance, I wouldn't even bother, the same with "powersave", and "interactive" drains the juice out of the battery as if it would frickin' leak. Again, this is only a suggestion. You could try to add one governor, a personal-original governor, one with a good balanced between battery and performance. Just like hellsgod added "hellsactive" to his "hellscore kernel". I mean that governor is fantastic, and I would love to see something as good as that in your Quanta kernel. "Interactive" or "performance" are just old, or at least that's how I see them. Also "interactive" is a bit better in "hellscore kernel". I'm not implying that your kernel wouldn't be good, cause it's great, but it can be better. I have used your kernel for a long time and loved it until I changed to hellscore Now, only you can decide whether or not to take into consideration my suggestion. I just wish Quanta to have a few more features and improvements in order to be the best, considering that it used to be my favorite kernel. Well, it was SaberMod when I started using it.
[Nexus 4 Android Development] zaclimon:
Don't worry about this, I'm not offended at all :p. I did have thought about a Quanta governor though without any real experience in C, I can't do nothing about creating my own Governor... nor doing "miracles a la Franco" :/ I'm also a little bit lazy about bringing my own stuff XD.

I'm not sure yet but, perhaps once I'm done working with QT, I may begin to work more closely into the kernel. I would like to push Quanta further and I know it does have that kind of potential. :)
[Nexus 4 Android Development] ARDV:
hello,

when i try to flash this kernel with CM recovery, i get: footer is wrong, signature verification failed.
[Nexus 4 Android Development] dragos281993:
Try to flash another twrp recovery. Build 2.8.7.0 is the latest one.
[Nexus 4 Android Development] atulclassic:
can you integrate hellsactive into quanta?
[Nexus 4 Android Development] dragos281993:
I personally hope not. That would be uncreative and would blow away the originality.
[Nexus 4 Android Development] zaclimon:
I won't add hellsactive into quanta. As dragos said, I want quanta to be unique with its own tweaks.

Also I said that I wouldn't add anything except what was already in the kernel.

Hey guys, I've begun some more interesting work on QT. (aside from optimizing) The screenshot below shows a widget that toggles your desired tweak when you press on it. (it is still far from being done as it is only a rough copy)

I wanted it to look like a miniaturized card from the app. It probably will look like it is the final design for it though I would still like to listen to your opinions regarding this.

Hi I have Flashed Quanta-V6 onto Liquidsmooth LS-LP-v4.1-2015-07-10-liquid_mako.zip and it inverts the colours !

Is there anyway to stop this happening ?
[Nexus 4 Android Development] dragos281993:
When the colors are inverted after flashing a custom kernel, it means you flashed the wrong version.

Also, this usually happens when flashing on top of a custom ROM, a kernel made for the stock ROM.

First try the other version of quanta v6 and see if you got rid of the problem.
[Nexus 4 Android Development] k500zm:
Thanks dragos - that explains it !

Hi zaclimon,

I just had a reboot. Can you figure it out why? I just flashed your kernel 10 hours ago (I was on hellscore and I didn't have a problem). My ROM is Euphoria.

I undervolt -100mv, max temp 60. I done this on other kernels and I don't have any problems.

Set voltage to stock otherwise all reports are useless even if you are able to undervolt -100mV with other kernels.
[Nexus 4 Android Development] ahoyboyhoy:
Low memory freeze

I love the Quanta kernel for CM12.1 even compared to the CM kernel and Hellscore kernel, both of which I'm also very happy with. What I like about Quanta is that it includes sound controls, wake controls and exponential display toggle while also integrating into the CM battery profile switcher (switches cpu governor like the stock kernel). After using the kernel for a couple of months, my main issue is with low memory. When all of the phone's RAM is being used, the kernel freezes, the CPU is pegged and the System UI takes a couple of minutes to respond to each interaction. Both the CM kernel and Hellscore handle this more elegantly and don't lock up so bad. Any suggestions or is this a known issue that will be worked out? Any additional information needed? I'm on the latest CM12.1 nightly, but I've had this problem for the past two months of CM12.1 nightlies.
[Nexus 4 Android Development] ObihoernchenDE:

Mouse via USB OTG / boot.img of Quanta V6

Finally I dropped my N4 and the digitizer is broken :(. Debug mode is off, the CWRP recovery cannot be operated due to missing touch. The last change to recover my data seems unlocking the booted phone with a mouse connected over USB OTG. Therefore I'd like to flash Quanta V6 to my AOSP 5.1.1 to use a mouse.

Is this possible? Is USB turned on by default after booting?

Where can a find a .img file that can be flashed by fastboot (as the recovery cannot be operated....)?

Thanks!
[Nexus 4 Android Development] AndyYan:
I think you can still recover a fair amount data in TWRP if you're familiar with ADB usage. Or better, just flash CWM/PhilZ via fastboot and use the volume keys - this is when these 2 outdated recoveries come in handy.

OTG is *off* by default.

The fastboot img is right inside the zip.

Hello zaclimon, thank you for your hard work. I have installed the test2 version of this kernel, after many reports that the freeze issues are gone. but i have some issues with this version.

FIrstly,i am using the CM version, and i am on 1Aug nightly of mako. I have been using this for the past 4 days, and initially all works fine. But in my observation, the OOM killing is not at all happening... i may be wrong, but thats what i have observed. I have never ever seen mem as low as 24 MB on mako on any ROM or kernel[with all cached process included.] Even after clearing all recents, the total available mem is only 260MB.

At this state, i took some logs.. if these can help.

Thanks .
[Nexus 4 Android Development] zaclimon:
Thanks for these logs, I'll have a look at them once I'm finished finalizing QT 3.0. (Hope to get it released this week) Though I do find it interesting that OOM isn't working correctly, might be something in the ramdisk perhaps. (Just guessing lool...)
[Nexus 4 Android Development] scissorscrush:
I don't know why I have the freeze issue and no one else with Quanta, where I have already factory reset and running cm now. Using hells kernel and no freeze but that stands nowhere to Quanta
[Nexus 4 Android Development] ashjas:
Check the above post from the maintainer. There are similar issues faced by me aswell... i attached logs during the issue. If you need to help, please back your claim by logs. Only logs can help him debug the issue. I am patient, that he will dig the issue. Trust him. :o
[Nexus 4 Android Development] zaclimon:
Just knowing, is it possible to have a copy of your boot.img? I may have to do some comparaison between both ramdisks.

Thanks. :)
[Nexus 4 Android Development] ashjas:
A backup of boot from twrp will suffice?
[Nexus 4 Android Development] zaclimon:
Sure, it should be correct.

EDIT: After checking quickly in a dmesg, I see that a process is trying to start but it can't due to some reason. I would like to shift to CM to try this out. I'll try to set up a multirom if that is possible this week.

EDIT2: Can I have a dmesg from shortly after you've booted up? Maybe I can dig up a little bit more which process can't start.

[MENTION=4217103]zaclimon[/MENTION] I have found a way to reproduce this issue sure shot and in a quick way...

I just happened to be creating a drivedroid blank image of size about 4.2G with Quanta kernel.. and within around 35% of the process, the phone got wayyy... laggy.. i couldnt even turn on the screen.. same symptom as i mentioned.. and boom 2 mins later, it rebooted itself.

To be sure of the problem is with Quanta kernel, i flashed back the default cm kernel, and created the same blank image with drivedroid again, and the process completed 100%, without any lags whatsoever.. so this confirms that there is some problem with Quanta + cm combination,the memory just keeps on piling up with OOM killing failing. (as you must be on aosp, so you dont get it).

Hope this helps in resolving this.

Cheers.. :)
[Nexus 4 Android Development] zaclimon:
[MENTION=3721932]ashjas[/MENTION] could you test this kernel. I've removed all modifications prior to V5. (I've added the most recent AOSP commits though) so it should be in a V4 like state. Can you confirm if you still have issues when using CM?

Anyone who also has CM is welcome to test. The more results we have, the better right? ;)
[Nexus 4 Android Development] ashjas:
Sure ... I'll test out this and report back... Thanks.

---------- Post added at 09:01 AM ---------- Previous post was at 08:41 AM ----------

OK.. Quick drivedroid image creation testcase passed... Image created successfully. Also kept an eye on the mem, it didn't pilled up. .

Now testing continues as a daily driver... Will report back if something interesting found...

Edit... Logs attached while successfully creating the drivedroid image... just in case you need for comparison..
