[Acer Iconia A700 and A510] Ziyan:
Here are some methods to get logs in case the device doesn't boot:

1. Sometimes, you can connect with adb on the green acer logo, and pull me the logs

2. If that doesn't work, hold down the volume down button (which is the first button of the recovery key combination), then press the reset button. After it vibrates for the second time, release the volume down button and press the volume up button - this way, it will reboot into recovery, without powering off - this is important, because this way, it preserves last_kmsg (which is lost instantly on a power-off) from the non-booting environment, and you can read it from the recovery through adb.

Anyways, I spend yesterday with updating the board files to be compatible with linux-tegra-nv-3.4. While it compiles without errors, it sits on the Acer logo yet, without usb and last_kmsg. The Nexus 7 guys have the same problem with it, so I've joined their hangouts chat to find the problem. There are some acer-specific ifdefs in some files all over the kernel, I'm gonna try those too. If anyone has some experience with tegra 3 kernels, PM me your g+ account, we need all the help we can get. 3.4 would be a huge improvement over 3.1.

As for 3.1, I've almost fully updated it to linux-tegra-nv-3.1 - just some very minor commits missing. I'm gonna apply those, enable UV/OC, then continue with 3.4 while the A700 is here with me, as I can continue improving the kernel without the device once I have a stable base.

Please try the attached file - I've changed the ramdisk to the one extracted from A510 CM11.

Also, anyone has some experience with anykernel? For some reason, I can't get it working on this device... it shows errors like unknown device type.
[Acer Iconia A700 and A510] Shreps:
FYI, on the A510 we are now using LVM to extended the /system partition.

A boot image without LVM on an installed ROM with LVM will not boot, and vice-versa

So the ramdisk is different using with or without LVM :)
[Acer Iconia A700 and A510] Elibl:
Nice one good looking so far on a510. Looks like cm11 and pa ramdisk are compatible :p

And yes lvm is needed since a few weeks: https://github.com/picasso-m-mf-dev...mmit/d5dc330e726bcc684aa9b03bcfe2be175713beff
[Acer Iconia A700 and A510] HornetRider:
So, now i'm a little bit confused. [emoji6]

[MENTION=2633638]Ziyan[/MENTION]: I use CM11 with LVM.

Is your kernel with LVM support?

If yes, i will test it tonight.

[Acer Iconia A700 and A510] Elibl:
In his last post he uploaded the kernel with cm11 ramdisk and as the lvm implementation is sitting solely in the ramdisk the last kernel has lvm support what i succesfully tested
[Acer Iconia A700 and A510] Sterist:
what's the button combination to get to the bootloader?
[Acer Iconia A700 and A510] Elibl:
I think it was:

Boot with Volume- and PowerOn, First vibration => Release PowerOn, Second vibration => Release Vol- and press Vol+ and toggle the rotation switch on and off a few times

or just:

Boot with Volume- and PowerOn and toggle the rotation switch on and off a few times

on a510 don't know if it's the same on a700 though
[Acer Iconia A700 and A510] HornetRider:
Correct, but for A510 you don't need to toggle the rotation switch to boot into recovery.

Somebody in the german Android Hilfe Forum testet the New A510 and this tab bootet.

I will test it also tonight.
[Acer Iconia A700 and A510] cyberdroidXDA:
Just flashed the new kernel on my A510 and it's working fine. I'm using TWRP and ROM with LVM enabled.

I can confirm the improvement in starting and leaving apps. Internet browsing is much faster in relation to the interaction between keyboard app and the Browser. The ROM itself is starting mich faster also.

I also ran a benchmark test with Antutu simply to see how the difference is (I know what to make of benchmark tools but it was just a test).

Before: 14603, 14778, 14968

After: 14860, 15065, 15120

Well done, we need more of this ;)

BTW: Is this kernel working with ART?
[Acer Iconia A700 and A510] cyberdroidXDA:
[MENTION=4493088]Shreps[/MENTION], [MENTION=2633638]Ziyan[/MENTION]

Just one quick question: Do you know if the A510 kernel is ready for the A511 tab also?

In general, the A511 and A510 are the same. The only one difference is, the A511 can be used with 3G.

Thank you.
[Acer Iconia A700 and A510] Ziyan:
Try it out, in the worst case you'll need to reflash your rom (kernel), but I think it will work, as I see no seperate defconfig for it.
[Acer Iconia A700 and A510] Shreps:
It depends if [MENTION=2633638]Ziyan[/MENTION] merged the A701/A511 commit on the Kernel source

Look at : https://github.com/picasso-m-mf-dev...mmit/ffd24fda9ef92115d46a7b2c55a0520e1ef17c07
[Acer Iconia A700 and A510] Ziyan:
Yes, it's merged.

Anyone got UART working? I saw a thread about it, but it seems like there were no real success about that... I don't have an UART device, but if someone has, I could use some logs with 3.4, it would help a ton (sadly, the N7 guys has no UART either)...
[Acer Iconia A700 and A510] BlueCity:
I flashed the kernel on A511. It seems to be working very well!
[Acer Iconia A700 and A510] HornetRider:
Okay, I flashed now the new kernel... A little bit later, than i planned. [emoji12]

Open and close Apps seems to be much faster.

I think starting from today, you have much more fans than you maybe imagine ;)

Got positive replies from A510 and A511 users that the kernel is working properly.

Great job! Many thanks.
[Acer Iconia A700 and A510] Ziyan:
So I gave another try to 3.4... I've applied some of Acer's modifications across the kernel files outside mach-tegra, compiled & flashed it, guess what? Nothing... then suddenly, it rebooted itself after some secs! So on the next reboot, I held down the recovery key combinations, booted into recovery and pulled this last_kmsg: http://pastebin.com/fhw4LS4K

The USB-OTG has stopped working, since i flashed this kernel on my A510.

Before it was working.

Will flash back the stock CM11 Kernel in the next days, to test it.

[Acer Iconia A700 and A510] HornetRider:
Flashed Stock CM11 latest build with LVM.

With the stock CM11 kernel USB-OTG is working.

All my sticks and external HDDs, doesn't matter if FAT32, NTSF order EXT are working.

With Z-Kernel none of them.
[Acer Iconia A700 and A510] Ziyan:
Just tried a fat32 pendrive with the A700, it works on that. I'll release the new stable build soon (today), I'd love to see a dmesg if it still doesn't work on the A510 :)
[Acer Iconia A700 and A510] cyberdroidXDA:
In my A510 USB is working fine. No issues with that.
[Acer Iconia A700 and A510] Ziyan:
Here's a new build for A51x. I need the following information from the dmesg:

board_info.board_id = 3163

I think it's the same for A51x, but I want to make sure about that :)

Also, I have to give back the A700 today... so I'd like a tester, who can test the builds before I mark them as stable, because posting them here is so slow... hit me on hangouts, my g+ info is in my xda profile. Any of the supported devices (A51x, A70x) will do.
[Acer Iconia A700 and A510] coolhot_fdb:
If i enter dmesg in Terminal Emulator it answers "Operation not permitted".
[Acer Iconia A700 and A510] Ziyan:
You need to enter it with root privileges. Enter 'su', before dmesg.
[Acer Iconia A700 and A510] coolhot_fdb:
Thanks, now it´s working. But i don´t find the line "board_info.board_id =" in dmesg.

I entered "dmesg | grep board" without result.
[Acer Iconia A700 and A510] Ziyan:
Did you flash the kernel from this post?
[Acer Iconia A700 and A510] coolhot_fdb:
No, my tab runs with original kernel coming with cm11 0711.
[Acer Iconia A700 and A510] Ziyan:
Flash it then ;) I've added that line in the last version only.
[Acer Iconia A700 and A510] coolhot_fdb:
I flashed your kernel now. I got the same Info as you "board_info.board_id = 3163". But now as i wanted to make a screenshot it isn´t there anymore.

Kernel is working - see the screenshots. But not all CPU states are used. Minimal CPU Frequency is 204 MHz. 102 and 51 MHz aren´t used. Can you fix this?
[Acer Iconia A700 and A510] HornetRider:
Thanks, nice to see a new build. [emoji2]

I will test it tomorrow. Or maybe tonight, if I find some time at work
[Acer Iconia A700 and A510] Ziyan:
Thanks, looks like it's 3163 for both devices. Acer just copied cardhu's board files, and added their stuff to it, so I'm now deleting unused code from them, which makes developing 3.4 a lot easier.

See this post about the frequencies. The A700 has 1920x1200 panel though, so I may decrease it back to 102 mhz for the A510... here's the relevant commit if anyone's interested.
[Acer Iconia A700 and A510] Ziyan:
I've received a report about GPS not working... I had to give back the device, so I'm back to publishing test version till someone becomes my tester :mad: so try this build. GPS was not finding any satellites before (it didn't even turn on), I hope it does now...
[Acer Iconia A700 and A510] HornetRider:
GPS ist working, with your latest build, USB-OTG also.

I wrote in the german Android Hilfe Forum, that you are looking for beta testers, hopefully somebody will contact you. I did it already via Hangouts.

[Acer Iconia A700 and A510] BlueCity:
How about the CPU states?

Does the kernel use 102 and also 51 MHz on A511 in the new build?

Best regards BlueCity
[Acer Iconia A700 and A510] Shreps:
Very good news :)
[Acer Iconia A700 and A510] Ziyan:
I've released R2 (DL from OP), hopefully it's just as stable as the stock kernel... nothing fancy added yet, it's like an updated stock kernel :)

Currently, I'm working on an unified kernel for A510/A700. There are compile-time ifdef's to decide which code path to use, I'm converting those to runtime if's, though it's not that easy, as per this commit, but I have an idea for this as well. This will allow one anykernel package for both devices. Also, I'm doing massive cleanups on Acer's device-specific code... it's messy, minimizing the necessary extra code added on top of tegra-nv-3.1 will ease 3.4 development a lot :good:
[Acer Iconia A700 and A510] BlueCity:
Where to download?

The Link in the first post seems to be "the old" one...

[Acer Iconia A700 and A510] Ziyan:
It's in the bottom of the first post ;)
[Acer Iconia A700 and A510] BlueCity:
The one in the first post is different to the one in post #153... now I am confused! ( z-kernel-r2-a510.zip )

I think it would be a good ideato always add the date in the filename!

For now I flashed this version: Sun Jul 27 21:29:31

Seems to be the newest one and seems to work well! ;)
[Acer Iconia A700 and A510] Ziyan:
Those were test builds I had to publish because I didn't have the device to test them :(
[Acer Iconia A700 and A510] Ziyan:
Here are two new test builds. The only change since r2 is that the kernel itself is the same for both devices now, the only difference is the ramdisk. The kernel itself should support both the A510 and the A700, so one anykernel package would work for any device ;) if someone would assemble an anykernel package for me, that would be great, as I don't have the device with me to test it (last time I tried, I didn't succeed).

I'm waiting the reports about it. Specifically, the touchscreen and display part, as most differences were in those. This build detects the board at boot, and uses runtime if's instead of compile-time ifdef's.

EDIT: A700 removed as it didn't work :silly:
[Acer Iconia A700 and A510] coolhot_fdb:
I´ll test it for A510 and report.

Is it usable for A511 too?

May i suggest to use version numbers containing build date in future releases. That would ease to recognize the latest version.

---------- Post added at 09:36 PM ---------- Previous post was at 09:00 PM ----------

Flashed it with flashify in CWM 6.0.5.0. Got two messages:

E:footer is wrong
E:signature verification failed

But works fine. No issues until now.
[Acer Iconia A700 and A510] Sterist:
yes, please please distinguishable version numbers :)

edit:

a700, installs but boot freezes immediately (not bootloop but freeze) with the white bootloader text mirrored in 9 or 12 different places and stretched vertically.

I tried using the reset button and going to recovery to get the klast and dmesg but still wasn't there :(

Since the update to M9/r2+-Kernel the power consumption shows a strange gradient. There is a overnight increase in flight-mode. Battery Calibration was used. Anyone else with similar phenomenon?
[Acer Iconia A700 and A510] Ziyan:
If you mean increased power consumption, try this app after you notice it again. Be sure to check it before you recharge, as the stats will be lost when you do that.
[Acer Iconia A700 and A510] coolhot_fdb:
Thanks, but i meant an increase of displayed battery level. For example 33% in the evening, 40% in the morning after sleeping in flight mode the whole night. You can see the rise at the screenshot.
[Acer Iconia A700 and A510] cyberdroidXDA:
In my opinion, this is nothing kernel specific because the first time I have monitored this behaviour was a couple of month ago.

I have asked the Rom developer (@Shreps) about this and he advised me to use the battery calibration app to fix that.
[Acer Iconia A700 and A510] Elibl:
Or just delete /data/system/batterystats.bin probably the same what the app does

- CM11 M9

It boots ok and seems to work. I see build informations ok...

But it doesn't seem to have any overcloacking options ?... still 1.4Ghz :-/

Did I missed something ?
[Acer Iconia A700 and A510] HornetRider:
No Overclocking. It's like a clean stock kernel.

But you can switch the governor to "ondemand". The reactions are much faster than "interactive".

It uses faster the higher frequencies than "interactive"

I would like to see the governor "hotplug" as an option. I can switch off unused cpu cores.

Sorry I'm not so active, I don't have much time to work on this, and on top of that I can't have the device to test, until September. Yes, R2 is like a stock kernel, but much cleaner and closer to the official tegra 3 kernel. Before adding features like OC, I want to make this as good and clean as possible.
[Acer Iconia A700 and A510] cyberdroidXDA:
[MENTION=2633638]Ziyan[/MENTION]

Don't worry, everybody needs a break from time to time.

And I truly appreciate your work. Especially, if you don't have a device for testing.

The custom ROM in combination with your kernel are getting the best out of this device and keeping it up-to-date.

That has to be stated also!

Thanks!!!

SOKP stands for Sonic Open Kang Project...which is purely compiled from source with our own range of modifications,cherry picks to make it All In One rom(AIO)....It contains cherry picked features from CM11.00 ,Bean Stalk,AOKP,SLIM,PA,Chameleon OS,omni roms adjusted modified to give best results to users....On the Top of this it has inbuilt Own DTS sound engine to provide original richer Audio & video effects to users.

this uses very less third party application in rom i can say all most zero....and we can generally see some roms are including tons of xposed modules in the rom by the name as customization...but we are using only 3 modules here.....that to optional if users want to remove it they can remove from system application remover in settings....Note that all customizations are hard coded in rom with out taking any help of other third party applications and mods....

now a days it became a trend that using others sound mod and claiming that their rom has ultra best sound....i dont feel any specialty in doing that this can be done by every single user by flashing 3rd party mod on top of pure cm rom.

But sokp has its own made tweaks which never available in market.....nor in any web....

I think i explained more so that you can differentiate sokp with sensonic or any other roms in a correct manner.....

This is my reviews about the ROM.

Coming straight to the point, this ROM is THE BEST OF ALL 4.4 ROMS!!!!

Boot animation was nice, this ROM is overloaded with lots of cool unique features! No lags, butter smooth! Performance and gaming is too good. And who could forget DTS feature? Sound is the best like any other sonic ROM.

Bugs-

Lock screen effect bug - The screen rotates anticlockwise and then lock. Not a major bug indeed.

Don't know much about battery backup.

Conclusion - ROM has many features in a nutshell and no lags! Small but catchy tweaks like small recent windows in recent app bar make the look cool and unique. Was bored too much by different versions of 4.4 ROMS which were quite the same. This ROM surprised me too much!

Gr8 piece of work Darkstryder and all the sonic devs! (Not a piece of work....but a big wrok, LOL)

[Galaxy S 4 Q&A, Help & Troubleshooting] jackal992:
Hi! I know about the annoying problem concerning the revoked capability of the apps to write to SD in kitkat.

I'd like to understand the current situation about this problem.

According to you will Samsung solve the problem re-implementing this feature? I mean, will galaxy s5 have the same problem?

Skipping every possible debate on the unfairness of this move by Samsung, if I have understood, the only solution now is to root the phone, isn't it? And as far as I know there is no way to root without losing warranty, I mean the knox counter will be incremented even if I come back to stock, isn't it?

But somewhere I read that this could be solved by app developers with an update. Is it true? According to me by now there aren't apps that with an update regained the capability to write to SD... Every file explorer can't write to SD (at least some features), poweramp can't delete files or edit tags if the files are on sd etc...

However my main question is the following one:

Is it normal that from pc (windows 8) I cannot rename folders in SD, and I can't move to SD files like flac? I mean files that pc prompts if you want to convert to a compatible file for phone. If I click to avoid conversion, the transfer starts and stuck immediately... What can I do?

Thank you very much!
