[Q] [P] Broken Offline Charging & Underclocking Resets After Screen is Off - Sony Xperia P, U, Sola, Go

Hello everyone ..
Well I have two problems here that happened after I unlocked my bootloader and flashed the awesome Nemesis Kernel ( over stock firmware with Fidelity JB 2.0 rom ).
Actually I wanted to post these issues at the Nemesis thread, but due to new membership limits I couldn't, so I hope that you guys can help, and especially @nicolassp
----------------
1. Offline charging is broken. I searched for this issue and came up with that it may be due a corrupted charger file after flashing a new cwm ( the one bundled with Nemesis maybe ) over a previous cwm. I don't know if a flashable undamaged charger file could do the job or not.
2. Underclocking issue. I was trying to underclock the cpu to 800 mhz using NoFrills app, it works at the beginning, but after you lock the screen and wake the phone up again it resets to default 1 ghz! I tried other cpu control apps with the same result ( Could it be some sort of conflict with Fidelity? ).
Anyway I appreciate any help from you guys, thx in advance

2. If you installed CWM before flashing nemesis than that is why you cannot charge offline, known problem, and it is still active BTW if you wait after nemesis CWM turn inactive pressing the volume down will bring up old CWM.
To fic this simply copy stock chargemon to /system/bin/ and set permissions to 755.
2. The ROM mod may have installed scripts that change cpu max/min frequency.

Thanks very much Chike, btw, can you kindly upload this file to me? ( and if it's a flashable zip I would appreciate this very much ).
And if it's a script by Fidelity that is causing the clocking issue, where could it be so that I can modify it?

Are you 6.2.A.1.100 based ROM?
The file can be extracted from system.sin in the ftf file, if not I can upload the one from my phone.
I don't know that ROM, I am guessing one of the files in /etc/init.d/ search for "/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq" and comment it out ("#" at the beginning of line.)

Yes please upload it for me because I don't have the ftf at the moment and my internet connection is so bad ..
Also I uploaded the screen-state script so that you take a look at it ..

You see the lines
Code:
echo $min_freq > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq;
echo $max_freq > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq;
and
Code:
echo $min_freq > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq;
echo $min_freq > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq;
You can simply comment the out or replace $max_freq with different value
Code:
#max_freq=`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq`;
max_freq="800000"
Rename old chargemon to chargemon.cwm in case you choose to use stock kernel again, and change it's permissions to 644 (no execute bit) copy chargemon to /system/bin and set permissions to 755 (read all, write owner, execute all)

You are right.. The script sets the max speed of cpu and there is no problem with Nemesis Kernel.Thank you

Thank You!
It worked! Thank you very much Chike and yes nicolassp your kernel is working like a charm!
