New FW I9100XWLPT(4.0.4)

Hi everyone firstly just posting general feedback that 3.5.2 works very well for me on 4.0.3 (Thanks GM!). Only thing is that my camera stopped working recently but this occurred while on 3.4 and it was working when I first flashed the kernel so I doubt it's a Siyah issue!

Anyway, there is a new 4.0.4 rom out from Samsung. Has anyone tried it with Siyah yet?

I9100XWLPT

Base Firmware: I9100XWLPT(4.0.4)

Everything is working very well but you may lose your CRT off animation. Somehow the combination of siyah and CM10 has killed it when there is no wifi connection.

EDIT: Leaving wifi on itself without actually connected will still keep the CRT animation.

About customizing amplifier gain.

How can i change the amplifier value in Extweaks?

This code is from res/customconfig/actions. A file named 'soundgasm_hp'.

To change the value of amplifier, I thought that i should change each '0 / 384 / 768 / 1536' thing.

But i can't understand why the value of 1.5dB is 384?

At the same side, why 3.0 / 6.0dB is 768 / 1536?

Sorry for poor english :(

Is anyone else having problems with auto brightness on latest siyah+cm9? Can't get it to work properly. Didn't touch any settings.
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
to be 100% sure, you'll have to get a datasheet and spec's of the yamaha sound chip used and look at what values need to be put in what registers to get certain function done. these are ussually binairy codes, which are broken down by the chip and used accordingly.

If you break these values down mathematically, you'll get:

384=256*1.5

768=256*3

1536=256*6

and 256 is the value of 2^8 (2 to the power 8) or binary equivalant : 11111111 or 8-bit word, better known as byte.

[Galaxy S II Q&A, Help & Troubleshooting] Mario1968:
Hi, tanks for your clear explanation, those values maybe are linear values (from 0 to 1536)? Like on analogue slider and the Dev has choices three steps of gain (1.5 3 6 db).

That I don't know..., because I haven't seen the spec's of the yamaha chip, but I think it's reasonable to assume that...but it may just as well be that it has only this (3 step) capability, The only way to know for sure is to just try, and see what happens....

It's reasonable to assume because the factor 1.5 doesn't translate to an even binary number, as with 3 ( binary 011 ) or 6 ( binary 110 ), meaning there must be steps in between, so probably lineairly adjustable......

As with all values and systems, these are bound to certain valid limits, which I also don't know which these are....and these should be stated on the spec's
[Galaxy S II Q&A, Help & Troubleshooting] maciekbe:
My 3 cents to sound boost.

There may be 2 reasons that Samsung doesn't use full DAC output. First, hearing damage loudness restrictions, which we find at portable players. Second, almost every audio output, near full volume has higher distortions. Samsung could decide to lower it for quality sake. These higher distortions can make impression of fuller sound. It will depend on music itself and overall volume setting too. I'm pretty sure, that boosting DAC doesn't bring any higher quality. Someone may just like the sound.

I have one good reason to use it, when watching a movie with low soundtrack. Another reason can be headphones with high impedance playing too quiet.

Using any kind of EQ may be good for compensating poor phones. Good ones are always better without EQ :)

Hi,

Is it me or the 3.5.2 is not as smooth as the 3.2.7.1 one ?
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
All the post 3.2.7.x kernels seem to be very critical with respect to the root management (su binary), whether you are using superuser or superSU. My personal experience is that siyah behave best with superSU. But maybe you are using that already....in that case try removing root in extweaks, make sure auto-root checkbox is checked and reboot....

After that open the superuser app (with 3.5.2 is that superSU) and make sure the binary is up to date. Let it settle a few minutes and do one last reboot, and see if it's better...

An idea for the dev thread?

From following the dev thread I have seen a mix of inappropriate posts as well as people arguing about these posts.

One idea I had was to have all real dev posts start with a twitter like tag such as #DevPost which would be easily identifiable and would be easy to sort out be searching for #DevPost in the search bar so GM could filter out all the FAQ posts etc. This might be useless but I thought I would share just in case it helps!

Example: http://www.google.com/cse?q=#DevPos...qefhnf&ie=ISO-8859-1#gsc.tab=0&gsc.q=#DevPost

Anyway looking forward to update 7 sources as apparently they help improve battery and performance further still not to mention native support for 4.0.4 roms without fixes. Big thank you to GM for all the work involved.

Sorry to hear that. Do you mean that you tried forcing mass torage or mtp mode in Siyah with extweaks and that still does not work? If not please try that! Reinstalling usb drivers for the phone may help as well and if not post back so we can try and help :)

Loss of cellular signal untill reboot

Yesterday I flashed my device with 3.5.2, everything looks fine.

I left it idle overnight, and when I wake up this morning, I discovered the phone loss cellular signal (I think almost 7 hours) and suffered massive battery drain (50% for 9 hour)

in /data/log it has generate a dumpstate file, which I think might be related to this incident.

by the way I have flash back to 3.2.7.2, which never generate such log file. I have noticed that it seems version 3.3.1 would generate such dump files few times a day, but never lead to loss of cellular signal that is not recoverable by itself as in 3.5.2

I had the very same problem with 3.5.2 recently as well. Cellular signal was unrecoverable without a reboot.

[Galaxy S II Q&A, Help & Troubleshooting] Zytrel:
The 3.5.2 changelog includes an "updated modem driver", so I was lead to believe that the kernel does in fact affect modem behavior. If it does not, mentioning it in the changelog wouldn't make much sense, would it? :)

Hi all, I've experienced two times the loss of cellular signal, one time during overnight (the signal icon is the circle with a slash over), I can't view battery drain because the phone was in charge for all the night; the second time I lost signal during the trip in highway for my holiday, this time too there isn't battery drain, only unrecoverable signal. To solve those signal loss I simply reboot the phone. Previously I was on 3.2.7.2 and never experienced signal loss, I don't change the other things, same firmware/modem/apps.

I as well am pretty positive that this is kernel related.

Maybe someone could bring this issue to the dev thread, so gokhan sees it, as I don't think he checks this tread that much.

I would do it myself, but apparently I'm a noob, and I don't feel like spamming a few nonsense posts just just to gain posting access to that board. =)

EDIT: Maybe it would be useful if everyone with this issue posts the ROM/firmware/modem they are on.

Like mentioned before, I'm on stock LPI (DBT/4.0.3) with XXLPX modem.

[Galaxy S II Q&A, Help & Troubleshooting] Tricks25:
Hmmm i thought kernel has nothing to do with modem but since people have opened up about signal loss, that got me thinking..

Since flashing those latest versions i have always had "x" in my signal bar which means i really have no signal..

Yes signal is very weak in our house but i never encountered having "x" in my signal bar before.. i already changed modem same thing..

Just sharing my experience..

I could try another kernel but nah too lazy to test.. :p
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
My opinion (not based on expertise, but pure logic)

If the kernel modem driver is updated, it gets new logic added and/or existing ones altered/updated. The only good reason for this would be to accomodate the newer radio firmwares (modems), and maybe inevitably the older ones may start behaving less efficient. So I think if you choose to go on forward, and keep updating to the latest kernel, at some point you'll have to consider updating your radio firmware aswell, to keep up with the newer version modemdriver.

I did just that, and it's working perfectly. The choice of the right modem is unfortnately dependant on your provider and region, so I can't suggest a universal one which will satisfy everyone. Just search and try a few...

Hi

I undervolted with ExTweaks to -75mv but then i undervolted more some freq with Setcpu .. Is it good to do that ?

Does i have to check " Set on boot " with setcpu ? because everytime i reboot it take the Extweaks undervolt settings ..

Or is it good that way to put just the what i want to undervolt with setcpu and everytime i reboot go to setcpu then reapply the Undervolt setting ?
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
As long as your phone works properly its fine. Extweaks can change voltages for individual frequencies. My advice would be to just use setcpu instead of using 2 different apps.
[Galaxy S II Q&A, Help & Troubleshooting] tlf55:
The things it's that Extweak needs to reboot to undervolt .. But why does Setcpu doesn't need it ? Is it correctly undervolted ?
[Galaxy S II Q&A, Help & Troubleshooting] #illidan:
Because they use different methods to UV. Don't know the technical part, maybe some else can explain that to both you & me but basically setcpu does it on the go while Extweaks requires a reboot for the UV to be effective.

[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
#illidan is correct in the sense that they use a slightly different method, but through the same interface.

Setcpu, Voltage Control, NStools, etc are dedicated apps that give you the possability to undervolt individual freqs. with different voltages.

But there's also the possability to increment/decrement all voltages at the same time, which is the method built in extweaks by GM.

The fact that you need to restart, is I think a choice made by GM, possibly due to the way he implemented it maybe?

Normally these increments/decrements can also be applied on the fly like setcpu, etc.etc. does it. (meaning in theory, also possible with extweaks).

You can read up on it in this thread, explaining the use of this interface.

http://xdaforums.com/showthread.php?t=821372

You can experiment using a script, and see if it will apply your increments/decrements on the fly...and if so, then maybe place a change request on the DEV thread for a future release.
[Galaxy S II Q&A, Help & Troubleshooting] gokhanmoral:
it is the implementation limitation as extweaks is not aware of the current state but it only displays the saved state.

if you undervolt by, let's say, -50mV then it won't be applied as there may already be an undervolting settings applied (using extweaks selections, other undervolting apps or scripts) before that selection.

therefore, I chose to apply it on boot only so there will be no crashes because of consecutive undervolting...
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
Thank you.....That very logical....didn't think of that

I guess a work-around would be to echo the 'neutral set' first, followed by the chosen increment setting, to be sure it's applied according to the users expectations....but that's a matter of arbitrary choice and implementation then.....
[Galaxy S II Q&A, Help & Troubleshooting] gokhanmoral:
the problem is that all cpu's default settings are different and it needs another interface to reset the voltages to defaults.

doable, but I thought it shouldn't be my priority to make undervolting easier/tune all the details.

I put that setting for some lazy users (like me) who want to have undervolting but don't want to spend too much time on tuning it for all the frequencies.
[Galaxy S II Q&A, Help & Troubleshooting] johnbeetee:
Totally agreed! There are ample other apps giving that posability, so why re-invent the wheel?

All clear now....Thanx!

What exactly is swap and zram config? Is that something like a virtual RAM on the SD card? Like the pagefile in Windows?

And also "no CAP_ERASE, no hardbrick"

I'm pretty surprised about that. Wasn't that fix already applied long time ago? Or is it possible to hard brick your device with a bug on earlier versions?
[Galaxy S II Q&A, Help & Troubleshooting] Tungstwenty:
Swap - The same as pagefile in Windows, yes

zRam (or compcache) - a mechanism to compress the memory to be paged out to a reserved area in RAM, instead of writing it to a paging / swap file on the slower flash storage.

I'm not sure if zRam can also be used as an intermediate step before using a swap file or if it eliminates it entirely - even if it can mean both it might depend on what GM choses to implement or what might be configured in ExTweaks. Personally, I don't think it's worth having paging on the flash storage as RAM is usually more than enough and flash has both a much slower response and a limited lifespan when written more often than needed.

The CAP_ERASE / hardbrick protection were always there. It's just been put in the release notes to make sure everyone can easily see it's safe (but apparently it's causing more confusion than reassurance :laugh:)
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
It was put there so that people would get it that it won't hard brick. It's already been like that since the infamous brick bug version. There's only one version that has the brick bug and now it's gone. Nothing produced from here on has the brick bug.

Today with Siyah 3.5.2 I've experienced new signal loss, then I reverted back to Siyah 3.2.7.2.

Now I wait for the new 4.0 release to test if this problem was fixed.

To clarify the signal loss:

I put my phone in my pocket today morning after a full charge, then I go to sea, at the 12:00 I see my phone and was without signal (the circle with a slash over) in this state the only things to regain the signal is to reboot the phone, after reboot I get message for a missing call. Another strange behaviour regards the battery drain after this loss, normally the battery loss 1 or 2% every hour, during this signal loss the drain is 6% every hour.

Anyone knows what is the cause for this signal loss?
