I restored to stock scaling in 1.5, to keep it close to stock. I will have to recalculate, but that sounds about right. Are you trying to go 3 days on one charge :).

Our board doesn't have that (msm8660) feature. You can always pull the current kernel config by issuing "adb pull /proc/config.gz"
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
Ok thanks, well that solves 1 issue but creates another, I still have no clue whats causing my unlock signal drops. Great work with the kernel!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
Can you elaborate? That sounds interesting, are you in North America? I can look up what specific things are done in the kernel for NA or you can do it too from the source link..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
I posed about it at q/a, as you can see by my flag I'm from Israel not so close to North America.

Most of the times when I wake and unlock my phone the radio signal drops out for about a minute, my gf claims it happens also when my phone is asleep and she gets to the voice mail a few times before it reaches me.

I tested it today with my brother's sim which is of a different carrier and I didn't see to have any issues for a couple of hours, also with my sim on his phone there were no issues. My guess is its a conflict between something in the phone to the carrier settings. Since returning my sim back I didnt see any issue's yet but it's still a short run.

In the worst case scenario if I wont find out the cause I'll change carrier.

Here's a picture from yesterday before the sim switch where you can see the correlation between wake+screen on to no radio.

Can you post your battery and performance results after a few cycles? Looking at using your voltages but won't have a chance until Sunday to do some major updates.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
Well, whether you notice the savings from undervolting, I don't know... You ARE going to save, since volts x amps = watts. But, since the 4.5" AMOLED and LTE radio pull the majority of power, you could probably undo your savings with a little extra use of a bright screen and downloading per charge (or some random app that wakes the phone up too much).

There's still reason to do it though, if you are stable, and that is reduced temperature (ah, hello again watt). I have definitely noticed a reduced heating of the phone while under-volted.

As to stability, the undervolting script posted has been pretty extensively tested on my phone. I've locked in each available frequency and run quadrant as well as SetCPU's "Stress Test" and have experienced no odd behaviors, reboots, or freezes. It's been undervolted at these settings for about 48 hours.

I just can't guarantee it'll be stable as all chips are not created equal. TSMC will bin chips as acceptable that fall into a range of performance, and thus voltages tend to not be catered to an individual chip.

Easy route for you to test it: download the script and just run it in Script Manager (w/ SU). It won't stick on a reboot, so if your phone acts up (or randomly reboots) you'll be back to the defaults quick.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] seanci:
Im having the same issue on 1.5 as 1.5 dev , overclock to 1.8ghz on performance using set cpu causes it to reboot, its not stable at that voltage i would recommend going back to max 1.73ghz, but then again what do i know. Maybe its just me but i tried reflashing rom, kernel, and radio and trying different roms and radios and still i see that instability. Please let me know.

ReedX50v Scripts,

Is it possible to set screen-off OC/UV via init.d scripts?

Scenario I would like to have a lower OC/UV while screen-off but have a Higher OC/UV While screen-On.

If this is possible would you mind adding some various example script to your OC/UV script list?

Thanks in advance

Is it possible to add unlocked "Rat" to Cymbaline, or has AT&T made this impossible?

was just reading about the new official rogers kernel bieng Rat unlocked and it made me wonder.

Thanks

Use an app or script to limit the max OC on your phone. Not all CPUs will be able to OC to the same max.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] marvin02:
Isn't it the radio that is (or isn't) rat unlocked? If I understand it right this kernel does work with Rogers rat unlocked radios, but there are no official unlocked radios for AT&T.

10 hrs with 24% left.. I fixed perms and restarted at lunch time.. That why it only says 6hrs..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
Yes, it will come in the next update, it is in my todo list..

Yes, it is possible. But I am not sure what that frequency is, sometimes it is locked in H/W both when waking up (that is lcd on) and asleep. Once you know what those frequencies are then you can set the voltage for those frequencies. (I don't know yet, what those are, been a little busy, I am sure someone would have figured out by than.).

Unfortunately, this is locked in the f/w (it is there in radio f/w files you flash), the kernel only provides the device interface. And yes, you can send those instruction from the ROM/HAL layer, it will accept it, but will return back with an error :( (last time I tried it, don't remember or it just ignores it). And we will never get the sources or the toolchain for these f/w, someone will have to hack the binaries..not me :).

Yes, anything about 1.72GHz should be considered experimental and may or may not work in all devices (See, Reed's post, above). I put it in to see what voltage works for anyone (if I didn't mention it in the OP). But if the CPU cannot handle it, nothing I can do. For my usage pattern (Browsing, calls, e-mail) it was stable enough, although for me extending battery performance is important, hence looking for ideal vdd levels..See Reed's scripts..

I am currently on a massive code update, the next update will come a later unless someone really hits an issue (no: OC issues though :), i.e. anything above 1.52GHz..)..

Also, has anyone tried MHL and USB OTG? They are enabled, I don't have any cables so cannot try it...will be interested in that experiment..

Ideas for CYMBALINE

Is it possible to set screen-off OC/UV via init.d scripts?

Thanks for reply I'm pretty sure that stock CPU Min/Max freq. settings are the same screen-off as screen-on. That is unless you change this with a capable app just my thoughts. Thanks again' you Rock I can't say it enough with out your works my SkyRocket would no longer be satisfying.

Or might you have been referring to the deep sleep CPU Freq's. if so this is not what I wan't to change I only want to change the freq. used for active screen-off condition and possibly the UV setting for the same screen-off condition ( CPU screen-Off being my priority request UV Scr.-off if possible but not 100% necessary)

(I hope this makes since like it does in my head)

Side Note,

I just noticed that the latest juice-deffender.apk update allows CPU changes similar to screen-off but it allows you to set a different freq for idle-use than active-use wich may mean the same as scrn-on/scrn/off but it may not be fully functioning yet as its still a new feature as stated in the app. I personaly tried to use these settings and it resulted in a reboot until i changed settings back.

---------- Post added at 03:50 PM ---------- Previous post was at 03:29 PM ----------

Mohan,

What do you think about the possibility of booting a second rom on the SkyRocket

Like the Siyah kernel allows on I777 GSII. Is this something you would be interested in venturing into or is it even possible on our device.

also EXT tweaks.apk Siyah some how adds Rec compatability to the CWM rec.img

that they use with the siyah release I used it before I switched to Skyrocket and it was pretty cool feature it allowed several things one I remember most is the ability to skip init.d scripts on the next reboot this came in handy for diagnoses quite often.

Just so you know I am aware of the differences between the two vareints as far as the rec.img being meshed with the boot.img on the I777 and the same .img's having seperate partitions on our I727 and I realize these tweaks would prob require compileing/coding of both .img's In other words you would have to include the Tweaked CWM Rec.img with your Cymbaline Flashable .zip. after doing the work of course I for one would pay for these tweaks and the furtherment of Cymbaline!

I've come to respect your opinion and I'm Just curious of your thoughts on these.

Thanks and again You Rock!

DuH the changes are in the radio

so I must ask now can AT&T users use a Rogers radio and have a working Rat unlocked rig on AT&T networks allowing us to change data 2g/3g/4g/LTE.

Thanks guy's a simple yes no will suffice. If you must haze me for asking send it to my PM. box:mad:

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
Yeah, some of the governors will lower the max freq, I think. The trick is to make a script that isn't governor-specific. I don't know if this is the most efficient route, but I think you may want something like this:

#!/system/bin/bash
# Insert your desired values below.
# This Script will always be running and waiting for wake/sleep states to be announced.
# This will set max to 648Mhz and restore Cymbaline's default voltages with screen off.
# When screen is on, this will set the max to 1728MHz,
# and restore the changed voltages to my UV script's settings.

Assuming the wait_for_fb_sleep is there, this should work, but unfortunately I don't have time to test this before I head out of town for a week. Give it a shot in script manager and see what happens, attached below...

(This is just the script, it assumes you want to OC to 1,728MHz, & Error Code 0 means it successfully runs in script manager).

Down side, is it will be another running process in background, but eh, it shouldn't eat much resources while idleing.

We'll see, I have a big script update of other features planned for when I get back and the next version of Cymbaline hits. :D

Edit: finally tested it, will have to fix the formatting. Coming soon. ;)

Thanks brother, I will try this out and post back findings. I'm anxiously waiting to see what comes of Mohan's kernel and your Script options I'am happy to say that i'm learning a great deal from these two Developers.:good:

EDIT:

Forgive me if this question has an obvious answer but i'm very new to running/reading/understanding shell scripts.

Question: If all I hope to achieve is the sleep part/second half of your script, is the awake portion of the script nescessary at all since cymbaline is already controling wake CPU.

Or is the wake portion of the script nescessary because after the sleep Cycle CPU settings, the wake CPU script settings are needed to reapply the Default/Cymbaline Frequencies?

Note: I have yet to run the script was just reading through your post and it sparked this questions and I symply don't

Know so I'm asking I hope its understandable how I worded it.

Thanks again for your help and sharing knowledge.

What rom are you using Rogers or ATT was wondering because I'm still on an ATT rom and was wondering if I have to change the build.prop cne module Rat settings to go along with the rogers radio I will be installing to get the unlocked rat.

Also do the edge and 3g icons show when you're connected to them or does it still show the 4g icon all the time.

I promise not to ask anymore rat questions in this thread thanks Guy's for not giving me a hard time.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Irfdiddy:
So im with rogers on the SKY-ICS UXCLF3 rom, and i have the UXCLF3 kernel flashed already. I was wondering whats the difference in that kernel and this one if all i want is BLN support? If i flash this kernel, will all the other features of this kernal automatically be enabled or would it be as if its stock and im just using BLN? Im sorry if this is a noob question but this is all i want to know because i dont undervolt and or OC and all the other stuff.

Thanks
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
I use my ROM (see sig), nope you don't have to change anything. The icon display is controlled by the ROM by reading the network info at your *current* location, if you have LTE, it should show that, HSDPA+ 4G, etc.. Read the OP/FAQ (Post #1, and #3) of my ROM (EMBRYO-3.2) thread I have tried to explain as generically as possible..i.e. you don't have to install the ROM..

The default kernel cymbaline-1.5 mirrors the stock settings very close, read the changelog for 1.5 in the OP, it has links to a post in this thread.

To repeat it, the only different from stock is:

* The min. freq. is 192Mhz instead of 384MHz.

* BLN support

* And all the extra modules that people wanted..

so if you do NOT undervolt/overclock, then as far as CPU is concerned, you should have the default (see above)..and it will remain as such in future revisions of cymbaline..

Please DO NOT install any scripts or change cpu settings via some app (since there are thousands of these) if you DONT want this, stay away from it, as you could unknowingly mess yourself up...

V6SuperCharger with CYMBALINE YEA-or-NAY!

I used V6SuperCharger for a while myself but I found that most of what it does can be achieved with the SystemTunerPro.apk.

That being said I no longer use it although I did leave my launcher supercharged. I also retained several of the scripts it provides especialy the detailing script. On top of running it (detailing script) every three days on a schedule, I run this script before and after I flash a new rom on top of the normal wipeDlvk.,wipeBatt., wipeCche.format sys.. The superclean script,(I run every 3 batt. cycles) the fast-engine-flush script (I run every 4hrs.) and the fix permissions script ( I only run when necessary after new rom flash and Tibu. user.apk install) I find these scripts fairly handy. they install to your internal SD when you run each one from the V6SuperCharger dashboard/options menu"mnt/sd/v6SuperCharger" you will also find these elsewhereif you are actively using the program.

Also Terminal users can install added busybox applets, and you recieve all the above mentioned scripts in ".sh" form for Terminal use also. all will be insalled to your "system/xbin" folder where your busybox binary resides.

I also found that a good majority of what the V6SuperCharger Script itself changes was already being done by the init.d scripts provided in the rom I was using. So you might check into this yourselves to avoid redundant and/or conflicting shell commands being applied and/or attempted. Also I think (could be wrong) the V6SuperCharger script itself could infact override some of the CYMBALINE settings as it tweaks init.rc

My findings are that CYMBALINE itself offers the best battery/performance comprimise thus far V6SuperCharger is simply not needed. "I.M.O."

Hope this helps somebody. Thanks not required I'm here to learn 1st.and to help 2nd.

Happy 4th everybody!

Hi Mohan,

First off thank you very much this Kurnel fixed the BT issues on ICS in the car!!!!

I just have one question, after doing lots of reading, it seems like a common problem with kurnels that if people use USB (computer,car or where ever) to charge the phone, then after unplug the phone will not go to DEEP SLEEP until rebooted.

This does not happen if wall charger is used.

Is there a chance you can take a look if that can be fixed on the usb charging?

Thank you

I'm using the skyICS-F ROM. And Cymbaline drains my battery twice as fast as Seans kernel does. I ran the experiment multiple times over night using the same radio, in the same location. I tried Cymbaline "stock" and under voltaged, and got the same reults. The screen was off, so this was just testing the standby battery life drain.

Mobile network was green the while time for both screenshots. On the cymbaline one wifi turned on closer to the morning, but the slope of the power drain wasn't really affected.

I'm using a wall charger, and restarted the phone each time, and in the morning made sure the phone was in deep sleep in all experiments.

Also, using the same governor and scheduler for both kernels. And not overclocking.

Any ideas?
