Twice now since installing 3.9 today i have been unable to wake my phone with a constant black screen, had to adb reboot.

Trying 3.9 without ZRAM now, to see if the problem goes away.. maybe the rom I'm using doesn't like it.

edit..Or it could/probably be completely unrelated; just saying in case others have the same error crop up.
[HTC EVO 3D] Szempy:
Last night i wake up my phone using sweep2wake, the screen lighted up, but the touch screen didn't responded, after a few seconds the phone got rebooted :-s

I'm using v13 ROM and 3.9 kernel 1188 MHz CPU clock ZRam enabled and the other are default kernel settings.

My Phone did not reboot anymore after applying Kernel Tuner Settings with Kernel 3.9.

I'm now restoring my device to the REALLY good working 14a release with CoolExe 3.8 kernel.

Have you got system tuner or similar installed?

Hi,

just wanted to report a bluetooth bug after upgrading to 3.9 kernel (all default values in aroma used).

First call is made or answered via BT headphone okay, but after that the BT is unresponsive, can not answer the call or redial...reverted back to 3.8 kernel, everything okay now.

I found out why my phone was deactivating vsync with v3.9

I had an old script in init.d which had it's permissions reactivated by 3.9 installer.

maybe this was giving me my black screen wake up problem..shrugs

[HTC EVO 3D] TheTeek:
No, only Kernel Tuner 2.4.

I've removed it now, re installed coolexe rom 14a (kernel 3.8) from backup and all runs smooth again, did remove Kernel Tuner by the way...

This version of the ROM was my favorite for my EVO, Coolexe did a really great work on this ROM, it runs really flawless!!

With Kernel 3.9 and Coolexe ROM 14a I had some BT issues, but I removed the trust between the headset and system, re added and after that it works again.

(now i'm back to 14a (kernel 3.8) because of the above mentioned probs I had.
[HTC EVO 3D] thomek:
I did try removing the headset and pairing it back couple of times, but no luck. With 3.8 no problems at all, so let's wait till cool fixes it...

Backup nandroid /data, install v14 (I'm sure it will wipe your /data too), then v14a and restore your /data backup.
[HTC EVO 3D] TomLeeDesire:
It has been said, check your existing init.d scripts before complaining about applied frequencies.

The aroma installer is great and very clear. I chose 192-1188 (well applied), and I just get an amazing battery life (after 12 hours of my personal usage, I get 60% left when I usually would get ~45). The launcher remains the biggest app sucker.

I've installed kernel v3.9 on rom v14a with 1,18GHz and I have to say, that freq remains on 1,51GHz.

In my init.d I have:

[HTC EVO 3D] TomLeeDesire:
I can't say. Just open them and read.

3 solutions

- something in them

- something in /etc/init...post_boot.sh (by example I tried badass but this one is putting governor back to 'ondemand' for both cpu)

- an app that put it back at starting time

[HTC EVO 3D] PlayPetepp:
If you're gonna flash v14 then no. The script to wipe /system, /data, /cache and dalvik is built into the flashing process. Just backup /data partition, flash v14, after that v14a and restore your /data and you should be fine.

I removed existing sweep2wake script before installation, and tried from menu to home. It isn't working. I don't know if it was expected, but no new script has been generated...

Another thing is that the aroma chosen frequencies are applied, but the existing init.qcom.post_boot.sh is putting both governors to ondemand, so the governor choice isn't working.

yeah scary has some problem but i will fix it in next version...:D

verify the cmdline settings.

adb shell

my setup

minkhz=192000 maxkhz=1512000 3dgpu=320000000 2dgpu=266667000 gov=ondemand scheduler=deadline s2w=1 s2w_start=HOME s2w_end=SEARCH

and remove ondemand footprints from init.qcom.post_boot.sh for custom governors..:D

r u sure u enabled it from aroma..?

try 4ext recovery...

Rom and kernel is tested with 4ext recovery...

adb shell
cat /proc/cmdline

then check ur minkhz freq.

check init.d script or init.qcom.post_boot.sh too

INFO: Now someone has problem with my aroma script...

btw i know recovery & aroma syntax batter then you..maybe thats why I'm using cmdline.sh for all cmdline options not like u scheduler.sh (copied from showp1984 kernel.zip:D)

check my zram script header..u will know my script comes from where...not like u who removed the headers and calming this is ur OWN WORK

The install procedure of v4.0 kernel with aroma installer is PERFECT! i am able to customize and set every option like i want it (for example, sweep2wake MENU to BACK button only, min and max MHZ for the cpu, the governor also) - I'ts AWESOME! No need to for additional cpu tweak apps. But Android Tuner is installed for monitoring purposes of course :)

Thank you

for adding aroma installercoolexe.

EDIT:

The problem below was because of my stupid router. It's a lame Thomson, which had problems the whole day, at some point wlan network went down, and router restarted itself, and wlan is now ok.

Kernel v4.0 now working ok, i choose governor badass to test it out.

But...

after flashing kernel v4.0 i have wlan problems. before i had v3.8 and other older kernels and never had wlan problems. now with v.40 governor (intellidemand and ondemand) i can't connect to my home wifi.

i'm 1 floor above the router and have poor signal, but with older kernel version i had no problems connecting to wlan and internet. now with i just can't connect to my wifi network until i go downstairs to the living room or the same floor level as my router. i'll flash the v3.8 again and see what happens then.

You can do the same for battery_charge xml and icons.

Hi Coolexe,

Thanks a lot for your work. I very much appreciate it. I have tried other roms and found yours to be the most stable. I very much like the sweeptowake function, its fancy :) On the other hand, i don't like the new configuration of sweep-to-sleep. Well, having the motion reverse is good and makes a lot of sense but it overlaps with the screen-shot feature. In my opinion, as a feed back, sweep -to-screen-shot is not very useful. There are already two other alternatives to take a screen shot. I mean how many times do you take a screen shot a day comparing how many times you turn on your screen and turn back on again.

I am also curious, there is a battery saver option in the quicksettings menu. What does it do?

Cheers!

Hi, I have got a problen with sweep2wake. Since kernel 4.0 it does not work. If I manually set /sys/android_touch/sweep2wake to 1 it works. So i have made an init.d script to set it automaticly to 1. But it does not work. The file /sys/android_touch/sweep2wake is 0 after reboot...

The init.d file /etc/init.d/50sweep2wake contains "echo 1 > /sys/android_touch/sweep2wake". Can it be, that the kernel does not support init.d???
