i am in serious trouble my friends. today i lost my network all of a sudden and when i checked, my imei was missing. since i am using siyah kernel i have a few efs backups. also the rom too backs up the efs. i restored the .tar.gz successfully using EFS Pro but after the phone has rebooted i saw that my imei has changed. also when i have checked the \system\efs i could see that only half of the files are there and the imei folder is missing, which is actually there in the backup. i tried it with all the backup and the results are just the same. can somebody please help me...

is it possible to restore the efs backup via odin

I use 500_1200 conservative with more tweak of governor...and battery life and speed are great!
[Galaxy S II Original Android Development] squall_kay:
mind to share ur tweak for conservative?
[Galaxy S II Original Android Development] Auridran:
I see this said a lot, but from what I understand it's just not true, unless you have a screen-off profile that limits you to the lowest possible speed. The same governor scaling settings apply when the screen is off, so if whatever process is using the CPU would've moved the frequency up from 100MHz to 500MHz while the screen was on, I'm pretty sure it'll do it with the screen off, too.

Why don't you guys charge your battery while you sleep? Seems to me all "battery issues" would be resolved with charging at night.

[Galaxy S II Original Android Development] DirkTeur Velserbroncx:
The battery issues i'm having are the same everybody has, to my opinion

it drains to fast using it does but even when idle it drains a lot faster then it did before so i dont know what your on about but charching overnight doesnt solve the problem with draining the battery
[Galaxy S II Original Android Development] tbong777:
I use my phone pretty heavily and get about 12 hours..which is great.(Also carry an extra battery close) I have never found a "problem" with battery life. I have drained the battery in 4 hours though using the phone but that is expected when the screen is on. I am sure the phone would last more than a 24 hours "idling". I guess I don;t understand. It's not like an iPhone where you have to find a charger. Batteries are cheap and plentiful. All this stress about a few hours more "idle" time seems strange. Its a powerful device USE IT and swap out batteries when you need to and use it some more. Unless you don't have electricity.......
[Galaxy S II Original Android Development] bala_gamer:
Did you tried copying the "efs" folder manually via root explorer?
[Galaxy S II Original Android Development] KennyLegend:
Great post man ;)
[Galaxy S II Original Android Development] :
Great post droidphile.

Also, I was really trying to stay quite, but I'm getting sick of good developers with bad attitude and no respect.

Yeah, that goes mostly to Entropy512 who could at least post in this thread and not hide in someones else thread to lick someones ass, but there are others also. Hacre ie. is great with funny personality, but he is not a selfish and egoistic prick. Wish he was here.

As most of you know, I'm using Siyah since ever, all alphas, betas, whatever.. Some where public, some where not public on like 70+ roms (as my counter proves) and there was not a single version of Siyah kernel that made my sgsii unusable for daily use. None. So that scientific statement from Entropy512 has no valid scientific base.

Only once I had made my phone unusable when I flashed a bad download.

Also as droidphile pointed out in pm to me, did anyone ever saw gokhan trolling around other people threads? Most if not all of his posts are in his own kernel thread, developing and supporting his kernel (which was not even in original development for too long). So there goes another scientific theory of gokhan being egoistic.

There are beta releases and stable releases. Betas do break things which are usually fixed in next beta release. Really!?

In the end, there are other kernels.
[Galaxy S II Original Android Development] harrynghiem:
I agree with you
[Galaxy S II Original Android Development] crypticc:
would be good to put this in beginning of Q&A thread. But with recommendation to google before further questions, well, because this is it!
[Galaxy S II Original Android Development] crypticc:
There is a whole thread about efs recovery. Try there. Before you do, check that you are not rebooting from recovery with power attached. I get that every time but reboot without power and imei is back.
[Galaxy S II Original Android Development] vijaysivakula:
Hi, Could some one help me with the backup of the EFS folder? This kernel is supposed to create an automatic backup but i cant find it. Also there is nothing in my data folder.
[Galaxy S II Original Android Development] Gowind:
Thanks for the reply my friends. by the way all is well now and i must thank gokhanmoral for that. i thought it was doom's day for me

i had the efs backup by siyah kernel, but was unable to replace it in system as root explorer wouldnt let me do that. no r/w in efs folder you see. from last night around 9, till now i am in front of the computer, tried so many things, nothing has worked out and you know what happened at last. was flipping through the app pages and saw blade buddy in one of the folders. never have i used it before. it has an option to mount system RW. did that, went to root explorer, replaced the efs with one of the backups, rebooted, didn't work.

again went to another backup and replaced it, rebooted it and...

and...

and....

voila...... everything is back...

so there is nothing like 2012 my friends. no doom's day. :D :D :D

[/B]by the way that efs **** has happened out of nowhere. if it can happen to me, it can happen to everyone. so make sure you backup your efs and get a blade buddy.
[Galaxy S II Original Android Development] spaxx24:
Blade buddy?
[Galaxy S II Original Android Development] droidphile:
Have you checked /sdcard. May be the feature auto backup of efs was removed.

To backups efs, in adb shell type

su
busybox tar zcvf /sdcard/efs/efs-backup.tar.gz /efs

To Restore the backup in sdcard (always keep a copy safe in your pc)

su
umount /efs
mke2fs /dev/block/mmcblk0p1
mount -w -t ext4 /dev/block/mmcblk0p1 /efs
busybox tar zxvf /sdcard/ efs-backup.tar.gz -C /

Reboot.
[Galaxy S II Original Android Development] vijaysivakula:
Thank you droidphile but i am a bit of a noob. i dont know how to work with adb. Didnt find anything in the /sdcard which is showing me the internal 16gb memory. Pls help me with the automatic backup process. Also, any resources on how to install and work with adb would save my life in an emergency.
[Galaxy S II Original Android Development] KennyLegend:
Look up efs pro app in the themes and apps section. It does it all for you.
[Galaxy S II Original Android Development] droidphile:
Learn how to install SDK and use adb from here

http://wiki.cyanogenmod.com/wiki/Howto:_Install_the_Android_SDK

(See the OS specific instruction of windows/linux whichever you're using)

Whenever you want to use adb, before connecting the phone to pc make sure usb debugging under settings>applications>development is checked.

After successfully installing sdk and connecting phone, type "adb shell" in command prompt/terminal to enter adb mode.

Then execute the commands in my previous post to backup.

:D

Anyone know when its supposed to be available?
[Galaxy S II Original Android Development] tolis626:
Dude,if it was so easy to brick a phone,no one of us here would still have their phones.Chill out and enjoy the modding.Everything(Well,almost everything except for some extreme circumstances) we do here is revertable.Best and easiest way?Do a nandroid backup.Even if everything goes too wrong,your phone won't explode,so restore your backup through CWM and you're still ok. :)

Woah!What happened here man?What did he do?I must be missing something big here... :confused:
[Galaxy S II Original Android Development] dannyc93:
LOL, oh ok ill gove it a try :D (just that phone kept freezing and rebooting when playing around with voltages and scared me a little lol)
[Galaxy S II Original Android Development] tolis626:

My script generator will be able to change this value also in beta 2.2, will release it very soon, only have to make some small adjustments.

[Galaxy S II Original Android Development] kwerdenker:
I'd say this is about this little gem from Entropy512. Just take a look at point 3...
[Galaxy S II Original Android Development] tolis626:
Thanks for sharing kwerdenker,but I already discussed the matter with vel1m1r via pm.Entropy is a good developer,but he should learn to keep his mouth shut for the greater good.

Although the idea of Gokhan having partners for his work isn't really bad,it's his choice alone.We,simple followers/users that we are,cannot ask or force him to change the way he chooses to work. :)

Well,maybe I exaggerated. :p

If my phone had rebooted that many times I'd be too worried about it. ;) :p

You are right though,I do feel like a guinea pig sometimes...I like it! :D

Check the link kwerdenker posted.Our friend Entropy512 has been too kind again... :rolleyes:
[Galaxy S II Original Android Development] gokhanmoral:
normally, I do not like to get involved in such discussions.

I have read his post yesterday and thanked to his post. I would be more happy to see his critics in this thread but it is his choice afterall...

he is not the first who criticize my style. although I think some of his arguments are not right It's his thoughts and decisions and there is free will, right?

in the past, there were some other developers who were talking about my source releases and criticizing me for not using git, someone even said that he didn't recognize me as a kernel developer for not using git while he was unable to use "file" command to determine the file type of my sources to be able to extract it. when it comes to critisizing, it is a never ending story, discussions never end and nobody gains anything.

there are some communities but I am not a member of any of them. I said countless times that I am not a kernel developer, I am an SGS2 user + some development experience. I am just adding features to this kernel and share it. I even created the thread in android development section although I have already put more work that some other kernel developers just to prevent this kind of discussions. like it or not... use it or not... also, I am always open to suggestions, contributions and requests. I am sure there are many users who can confirm this, I responded many PMs about requests and suggestions. However, I "do" what I want to "do". "do" may be a C keyword for some people, some people use it as a verb for female counterparts, I use it more in "do-178b" in my work. I have my reasons of not using git or testing many different ways in the code... if there is a strict rule that I should not release beta versions or that I should use git, I may try to adapt or leave. if not, I respect that he is leaving.

as for my ego claim, I won't defend myself... I will use my popular phrases which are the reason of some people defending and supporting me on this: "I don't know", "maybe he is right". "thanks to him anyway".

let's not talk about this anymore and get ready for the next beta :)
[Galaxy S II Original Android Development] chowlala:
That's actually true. But placing it at 100mhz also means your kernel had to ramp more. Which can cause lockups etc depending.

This is really for those who care bout every lil damn bit. Wait. That's why we're here in xda right? Lulz!

But it is true that using the highest ghz with lowest voltage only works best with a screen off profile like on setcpu.
[Galaxy S II Original Android Development] kwerdenker:
I must say gokhan, I admire your zen like position in these matters. Neither *****ing developers nor demanding users seem to rattle your cage :) That's propably the thing that makes you the most accessible developer I have seen on these forums. Keep up that spirit! :D
[Galaxy S II Original Android Development] droidphile:
Gokhan

Whatever people like Entropy512 says, our perception about you will never change.

There are very good reasons why this thread has 1.5 million views and 1000+ pages.

We all love Siyah kernel. We all respect you.

Like some user posted in this thread before, with you around, anything is possible on our beloved phone.

Keep up your good work. Let development win, and ego lose.

Dude,don't give a crap about it.You kick ass,get over it and stop being modest,you're getting on my nerves! :p

Anyway,you stay here.No one will force any of us to leave.Ok? ;)

So,back to beta16 for you! :D

I'm kidding on the last one but anyway.Have you actually tried overclocking the bus lately?I know you had said something about it,but it's been long since you last mentioned something...533MHz busfreq would kick ass eh? :D
[Galaxy S II Original Android Development] gokhanmoral:
beta16 is up.

I could not test every single line in tweaks.sh because I am going to a friend's wedding.

May be just me :) but

First impressions on beta 16:

Fast, super fast. Just noticed time taken for GoContactx to launch for the first time (ondemandx). It's the fastest i have seen for any release.

Digging in to tweaks.sh to see what tweaks i can include (chuck the remaining) in my init.d script.
[Galaxy S II Original Android Development] CamoGeko:
Same first impression here, much smoother on vr scheduler and lulzactive governor. :D

No more lag on lulzactive! :) Also Voodoo Screen Tuning working fine.
[Galaxy S II Original Android Development] armanderli:
I've never understood why some betas didn't boot on my phone...Betas 16,12,11,7,6 didn't work...whereas betas 15,14,8,5... was able to boot on the same configuration (I9100 XWKJ3 stock rom )....I guess it all comes to lottery or luck as far as I am concern....
[Galaxy S II Original Android Development] bragon2010:
Maybe you have an UV/OC script in init.d folder. Delete it before flashing the new beta.
[Galaxy S II Original Android Development] droidphile:
Uncheck boot settings on SetCpu/Voltage Control/No Frills before you flash a new kernel/release.

Also, move 'your own' init.d scripts which has oc/uv/uc code in it to a different location.

After kernel flash, and couple of manual reboots, tweak your script and move it back to init.d or reapply boot settings on setcpu/nofrills/voltage control
[Galaxy S II Original Android Development] John E Dante:
First impressions of b16 (compared to b15):

*Noticable faster

*Much smoother

*New features are working like a charm

Awesome!
[Galaxy S II Original Android Development] gokhanmoral:
This is very useful info for me because I use different compiler and options for beta releases. I will try to find the reason of that problem. Can you please check once again the beta version numbers?
[Galaxy S II Original Android Development] eXnikaru:
May i know how is the new feature work? the voodoo?

I cant see any diff between native and samsung...

and may i know how to chg GPU frequency..i am from speedmod
[Galaxy S II Original Android Development] iron@ss:
On CheckROM3.1.1. Using Launcher Pro.

Beta 16 installed with all SetCPU settings off.

Used Ultimate Kernel Script.

All governors are smooth except for... smartassv2 and lulzactive.

Both are very jerky in Launcher Pro app drawer scrolling.

This has been the case in the last few betas.

The last beta that these 2 governors performed well on was beta 6.
[Galaxy S II Original Android Development] John E Dante:
For the voodoo app to work, make sure you have the display settigs to "Standard" and not "Dynamic" in Settings.

The GPU-frequency can be set from Voltage Control which you can find at the Market.
[Galaxy S II Original Android Development] jdmcivic:
@gokhan

just to clarify. are the tweaks from tweaks.sh the ones removed from beta15?
[Galaxy S II Original Android Development] John E Dante:
And Gokhan,

Both lulzactive and smartassv2 are smoother for me in b16 compared to b7 through b15. Although they ain't flawless. The app-drawer lags I had with the smartassv2 governor is less frequent and more "fluent" than before. Don't know if this helps but I though I'd share.

EDIT: Might even be less jerky than on b6. And lulzactive has never been this smooth at swapping launcher desks or scrolling both fast and slow in browsers and other apps. Keep up the good work!
[Galaxy S II Original Android Development] manyakurt:
on official miui 1.11.18, best ever!
[Galaxy S II Original Android Development] cheewaca:

For voodoo screen tuning app to work you also need to have autobrightness enabled and not manually set it to lowest brightness.
[Galaxy S II Original Android Development] tolis626:
1)Who is arkadas? :p

2)No,Samsung shouldn't release the GS2 with Siyah preinstalled.Imagine the sheer amount of noobery that will flood this thread! :eek: :p

We don't need those.Gokhan will write DarthVader and DarthSidius,aka Emperor,governors!MUHAHAHAHAHAHAHAH! :D :p
[Galaxy S II Original Android Development] John E Dante:
Yep, no need to turn the screen off/on then :)

But once you changed it, you don't need auto brightness on no more.
[Galaxy S II Original Android Development] KcDaRookie:
Arkadas means friend in turkish.

Yeah, didn't consider that, you're probably right ^^
[Galaxy S II Original Android Development] nerotix:
How does this Voodoo Control App work? I installed it but when I open the app I can't rly change any settings, this is a first time for me using voodoo stuff at all :) Could someone perhaps explain? I'm on GalnetMIUI 1.11.18.

Thanks
[Galaxy S II Original Android Development] John E Dante:
As I stated before:

*To change the rendering style from Samsung to Native, make sure you don't use the Dynamic/Movie screen setting (use the Standard).

*To see the changes in real time when swapping through different gamma settings, use auto brightness (turn it off when you're done).

*Make sure that your kernel supports all of the options.
[Galaxy S II Original Android Development] :
And it's not voodoo control app if I am not mistaken, but voodoo screen tunning app.
[Galaxy S II Original Android Development] olifee:
This is indeed useful information for gokhan ;-).

As he already said, can you check the versions again whether they are correct?

Do you use any UV / OC / special init-scripts?

What does 'not boot' mean exactly? Does it bootloop, freeze immediately at lockscreen, or does it freeze / reboot some 30-60 seconds after the lockscreen appeared?

Do you have the possibility to provide a logcat / dmesg in case one of the latter cases holds?
[Galaxy S II Original Android Development] tolis626:
You should always consider the noob factor here. ;)

And in Greek arkadas is the one who is from Arkadia.That's why it seemed strange to me. :p
[Galaxy S II Original Android Development] olifee:
Finally I also have a question concerning the new voodoo screen tuning support ;).

I have already been using the app before the new kernel-module was included. Changing between Native / Samsung and the Gamma-values already worked then.

I see that the module also gives support to change gamma via sysfs. Is this the main point of the module, or was there also something not-working in the app before which my blind eyes just did not notice? ;).
