[Galaxy S II Original Android Development] Tiu Fiu:
Gokhan, I've got some (rather unfortunate) battery drain feedback on v3.1 for you:

Last night I flashed v3.1 with a full "cache-dalvik cache-and-reset extweaks profiles" (just as I always do after flashing a new kernel) and this morning, after taking the phone of the charger, I noticed a little increased battery consumption - I took the phone of the charger at exactly 08:00 AM and at approximately 09:55 AM I woke the phone up and activated PowerAmp (at this point the battery was at 92%). At aproximately 10:10 AM I deactivated PowerAmp (battery at 82% and with a severe overheating in the rear camera area.

So to sum up:

(i) From 08:00 AM to ~09:55 AM - The battery went from 100% to 92% (with absolutelly no usage - the phone was supposed to be at sleep)

(ii) From ~09:55 AM to ~10:10 AM - The battery went from 92% to 82% with only PowerAmp running and with an unusual overheating in the rear camera area (battery temp was around 48-52°C).

As a comparison, yesterday (when I was still running on v3.1rc6) I unplugged the phone at around 12:30 PM and by 05:00 PM the battery was still at 95% (which impressed me and made those numbers stick to my head).

I went back to v3.1rc6 at 10:15 AM this morning and everything seems ok (roughly 45 minutes with the battery marker stuck at 79% - with v3.1 it should have decreased 2-3% by now - and battery temp at a solid 26°C - should be at least around 33-35°C with v3.1).

If there's anything I can do, let me know. I'm not at all a programmer/tweaker, but I've been using your Kernel for so long now and I feel if there's anyway I can help, you have but to ask...

Best regards,
[Galaxy S II Original Android Development] vektek:
Bieng one of the people who has ended up with a bricked device I would just like to say a very big thank you for your empathy for us but please don't feel guilt. we all take a chance when we flash our devices and i trust all the devs always do their best to make sure it is safe to flash. it is not defeat. it is a learning curve. once i'm back up and running I wouldnt think twice about flashing again.

Best regards,

Kev
[Galaxy S II Original Android Development] rodries:
After read the reports about hard brick seems that the problems is in Wipe Factory/reset code. So is it possible to remove that option from cwm? and probably replace by a script to mount mannually the partitions and format them.

I'm not an expert, so I'm guessing only, sorry if I said something wrong
[Galaxy S II Original Android Development] cybrid3:
Hi guys,

If I know I definitely have the bad kernel installed, can I flash 3.1 from cwm or is it advised to do it through odin?
[Galaxy S II Original Android Development] narcosis34:
No dont flash if u afraid and GM is not responsible to any damage to your - our phones.

We have to thank him for all his effort and not making him feel sorry about bricked devices.
[Galaxy S II Original Android Development] TheFaixy:
I have flashed through recovery will that do something wrong?
[Galaxy S II Original Android Development] toinktoink:
the f*ck, i just answered your (same) question multiple times already.

why don't people start reading? -.-

anyway, for the nth time, it is automatically backed up to /data/.siyah when you flash siyah kernel.
[Galaxy S II Original Android Development] Crescendo Xenomorph:
@Gokhan: I got one problem: sometimes CWM and ExTweak unable to recognize what kernel I'm on (although I'm always with Siyah Kernel all the time, never switch kernel since I know this back when using latest GB).

CWM simply saying: unknown kernel. ExTweaks just say that I need to flash Siyah Kernel.

When I reflash the kernel through CWMR, its all OK again.

What cause that, I really don't know.

But, which way do you recommend: CWM zip or ODIN tar?
[Galaxy S II Original Android Development] pauch_19@yahoo.com:
yeah i read it and i read it right..i guess it wont hurt to just re-confirm. after what's happened and after all the confusion from everyone, we who were not affected should be lucky not to have experienced what happened to those phones that got bricked. i have high respects for gokhan that's is why i addressed my question to him directly.

at any rate, yes i got my answer straight from gokhan and that's all i needed.

lets just all be happy for this development.:)
[Galaxy S II Original Android Development] Rawi666:
I think I found solution to FRONT Camera FC on CM9 22/04

- Flash latest Siyah 3.1

- UNTICK Settings->Storage->Storage Configuration->Use internal storage

- Reboot

From now /emmc will be your internal card and /sdcard external

Camera app now saves images to /emmc/DCIM and I don't have any Front camera FC anymore
[Galaxy S II Original Android Development] pauch_19@yahoo.com:
i think if the question was not asked you would still feel the same. as i have said awhile ago i guess after all the confusion from everyone, it wouldn't hurt to reconfirm right? we take responsibility for the actions we make but it also means that we have to take cautions. i admire gokhan and the time and the work he has place just to make us all happy. it wont be fair to blame him when we ourselves know that there will always be risks involve.

so im not afraid..in fact im getting ready to flash.:D
[Galaxy S II Original Android Development] fedort:
I was on the rc6 with camera fc yesterday. Because of the camera fc I switched to another kernel, not knowing about the troubles with the rc6.

I read here to not wipe anything before flashing, but I did... I used Cleaning Script before going to another kernel. Am I safe now?
[Galaxy S II Original Android Development] silverfox88:
gokhanmoral posted that is safe to flash tar via odin or the zip with CWM app, not the recovery
[Galaxy S II Original Android Development] gokhanmoral:
I always use odin method or flash tar with CWM app.

in the early days of development I wasn't providing CWMR zips but the demand was so big that I also made it available.

people from htc world like cwm recovery more.

and about wiping in CWM recovery: there is nothing wrong in that part.

I suspect that device being wiped is being changed unintentionally because of a bug.

so, using cwm recovery wipe or script won't make a difference.

the current cwm recovery in cm9 sources do not have any known bugs in wiping part. it's being used in numerous devices.

the same problem happens with galaxy note leaks, i777 UCLD3 leak and m250l/s/k kernels.

I was just too unlucky because the reason of those problems were believed to be an improperly packed CWM recovery and nobody was thinking that the kernel code had any problem. that m250l (actually all l, s and k sources are the same) which I based my patches on is not a leak and I downloaded it from samsung's official site.
[Galaxy S II Original Android Development] sefrcoko:
Important to go through 2 or 3 battery cycles after flashing new kernel to take care of any calibration issues before judging battery drain. Also, best to check for wake locks using "better battery stats" from the Play Store to see if any apps are keeping device awake and draining battery.
[Galaxy S II Original Android Development] sgunf:
This is the right attitude!

I know that one can feel angry looking at his bricked black brick(:D, sorry for the joke, max respect and empathy to all victims of bricked SGS2), but after then, chilling out and reasoning: everytime we flash a kernel we have to keep in mind that it's not 100% safe, and what happened has to be considered a terrible fortuity.

So please don't rage on Gokhan with unhappy pictures as the "coffin" with "killed by siyah" written on it or sentences about not trusting him: he feels quite bad on his own, yet.

Keep up the wonderful work GM! BTW everything is working fine with 3.1, for me!
[Galaxy S II Original Android Development] duff91:
Thx for your work GM!!
[Galaxy S II Original Android Development] ilikesamsung:
im having problems connecting to my sch WIFI, ever since rc06 and rc3.1. need to revert back to rc04/05, can someone upload it for me?
[Galaxy S II Original Android Development] Ogy77:
I read and search but i am confused,can anybody give me answe,can I now download rc6 from GM site and flash,just difference from 3.1 is issues on CM9 with storage?
[Galaxy S II Original Android Development] Cristiano Matos:
Exactly.

RC6 is back to normal and only difference of 3.1 is the mount points.
[Galaxy S II Original Android Development] DforDesign:
hey guys. I'm offering 10$ for helping me out with cm9, syiah 3.1 and xbox 360 contrller for windows with wireless receiver
[Galaxy S II Original Android Development] cheewaca:
It is strange that the problem is due to CWMr.zip. I know a case of brick in which she suffered after installing the korean rc6 by CWM app. Once installed the rc6 had been restarted with the intention of installing the nigthly of 22 and when she wipe data factory has been bricked.

Another strange thing happened to me with that version is that most of the time after switching to another kernel from that version did not come often to reset the screen everything was sometimes striped color and other white and gray and had to restart with the power button.
[Galaxy S II Original Android Development] darkgoon3r96:
Charge cycles don't make any difference, the only problem he is having is wake locks. There is no way to calibrate the chips in our batteries, so charge cycles won't make any difference
[Galaxy S II Original Android Development] Crescendo Xenomorph:
Thanks for the advice... :D

Yeah, I got this problem 5 times already (4 with my phone, 1 with my fiance's)... I thought my phone was broken (dead flash chip or something like that), since no way the kernel is gone by itself. Then just now my fiance's phone also the same, then mine again.

I'll reflash it via mobileODIN then... :p
[Galaxy S II Original Android Development] noobsgs2:
So what's the differences between the very old rc6 which was 3.0.15 (not korean) and the new rc6? new one is updated to 3.0.28 + 3.1 changes?
[Galaxy S II Original Android Development] ellimist87:
On latest rc6 (post korean source) and 3.1, I'm missing ondemand suspend freq in extweaks (don't see it in system as well)

Anyone facing the same thing or it's just me? A fellow forumer (on another forum) confirmed the same as well on 3.1 iirc
[Galaxy S II Original Android Development] Cristiano Matos:
+ 1
[Galaxy S II Original Android Development] Josuhu:
They dont want to read your angry replys. Calm down.
[Galaxy S II Original Android Development] MSAKK:
"No externel storage available" when trying to access gallery or using camera, I don't have sd card.

What's wrong?
[Galaxy S II Original Android Development] gokhanmoral:
right, it is removed.

I will introduce system-wide limits on suspend frequencies later.

I removed all ondemandx and intellidemand changes from the ondemand governor.
[Galaxy S II Original Android Development] ellimist87:
Ah cool, thanks for the confirmation :)
[Galaxy S II Original Android Development] MSAKK:
Anyone please?
[Galaxy S II Original Android Development] Dark Emotion:
Hello guys, I have rc6 kernel on my phone and I heard about bricked phones after wiping a device... How can I prevent that? Thanks
[Galaxy S II Original Android Development] Ogy77:
GM I dont like use Odin,and well when I want flash new version kernel I flash with recovery wipe cache and dalvik,so now is safety to flash RC6 over CM9 stock kernel

nigthly 2204?

---------- Post added at 05:42 PM ---------- Previous post was at 05:40 PM ----------

Download latest RC6 and flash with CWM app,you dont need wipe anything.
[Galaxy S II Original Android Development] gokhanmoral:
please give more details if you need answers.

you didn't even specify your rom.

is it your primary rom or secondary?
[Galaxy S II Original Android Development] jack_p75:
Just one question i hoope someone can answer i need to do a full wipe and sd card format but the problem i dont like lost

My second rom if i put my second rom in to my pc and then copy again in to sd card do you think the kernel recognize again the second rom ????

[Galaxy S II Original Android Development] MSAKK:
I'm on Hydro3en ICS, don't have secondary rom.

I can still access the data on the internal storage in file explorer but they are on sdcard folder.
[Galaxy S II Original Android Development] gokhanmoral:
you have to use rc6 if you are on hydrogenmod. not v3.1.
[Galaxy S II Original Android Development] gokhanmoral:
yes, if you don't install any rom that wipes hidden partition all you have to do it to backup data.img and cache.img files and put them back after you format your sdcard.

just make sure that you don't wipe hidden (preload) partition.
[Galaxy S II Original Android Development] beston94:
So...I'm guessing me flashing this on CM9 22nd build is safe?
[Galaxy S II Original Android Development] MSAKK:
Well, I didn't know that, will v3.1 be available to Hydrog3n anytime soon?

Thanks
[Galaxy S II Original Android Development] AvRS:
RC6 is the same as 3.1 just with the old mount points. When your ROM changes you can then use 3.1.

Sent from my GT-I9100

[Galaxy S II Original Android Development] Skye Menjou:
Seeing nobody actually bothers to read the previous posts, due the way how the kernel was botched and how it botched the vital software such as the bootloader, a JIG wouldn't help.

People tried it already. Only JTAG can fix it.
[Galaxy S II Original Android Development] noobsgs2:
You cant enter download/recovery mode?
[Galaxy S II Original Android Development] Cristiano Matos:
Thanks GM.

I'm with new rc6 just because this mounts "incompatibility" in cm9 22.04.

You will upload 3.1.1 today?
[Galaxy S II Original Android Development] gokhanmoral:
in 10 mins if it works as secondary rom.

swapping is about to finish.
[Galaxy S II Original Android Development] Skye Menjou:
With what happened, no. I believe the bootloader is FUBAR.

This is why I always wait with flashing stuff to see if any bugs pop up and if its worth it(So let the early birds test it, its not worth living on the bleeding edge when it can brick it).
[Galaxy S II Original Android Development] Cristiano Matos:
I think already have a today cm9 build!

anyway gokhan can u confirm that my rc6 which has 3.0.15 sources should be safe?
[Galaxy S II Original Android Development] pauch_19@yahoo.com:
I can confirm usb otg working on rc6. connected a mouse and it worked! no luck on usb flash drives though.
[Galaxy S II Original Android Development] Cristiano Matos:
In doubt, do what Gokhan said.

Flash a new rc6 without any kind of wipe.
[Galaxy S II Original Android Development] sefrcoko:
Was using Siyah 3.1 but switched to new rc6 today due to the mounting issue with one of my roms. No problems with primary wanamlite 11.1, but on secondary D4 7.0 external SD was being used as internal and vice versa. Problem still continuing now on D4, whether storage setting is ticked or not. Been reading the thread all morning and understood things, until this... Am I missing something, or will this also be fixed in 3.1.1?
[Galaxy S II Original Android Development] rauschkugl:
for gods sake. can you please start to read the thread. does really everyone need the confirmation that his rc6 version is save or the new versions are save. everything has been said a dozend times!!
[Galaxy S II Original Android Development] AndreiLux:
Bug I discovered while measuring:

While having single-core mode on, and changing the frequency via profiles or any other methods (example, limiting the screen-off frequency), will cause the second core nonetheless to be turned on and stay on.

I remember in the Siyah 2 days that when turning on the device out of deep sleep, the second core would not be on unless there was high load. Now it wakes up with both cores firing up. Related?
[Galaxy S II Original Android Development] pauch_19@yahoo.com:
hi gokhan,

hate to break it but stock front cam seems to crash after taking a pic. not that im a big fan of front cam but maybe you could look into it.

other than that everythings seems ok with rc6. will update further.

thanks
[Galaxy S II Original Android Development] gokhanmoral:
I will have to delay 3.1.1 because of the problems that I have to fix with cm9 being the second ROM.

hmm.. I hope that one was not based on 3.0.15, was it?

then it is korean base.. I don't remember making any modification that would cause a change in that behavior (except for removing ondemandx which I removed two days ago) and korean sources have some modifications (even optimizations) in cpu & hotplug code.

maybe your freq_min setting is 500 and that was preventing the second cpu becoming active when you turn the screen on with ondemandx.
[Galaxy S II Original Android Development] kilian7th:
Don't have this problem on Hydrog3nICS 0418 + siyah 3.1 but I see music and Picture in double, do you have this issue ?

With siyah 3.1 RC6 too ...
[Galaxy S II Original Android Development] Ogy77:
So what we can now to flash,can you give advice:)?
[Galaxy S II Original Android Development] AndreiLux:
No, it's on 3.1 and I think I've had it earlier. It's simple to check it, just go to Tegrak's app to see CPU states, put into single core mode, and change frequency, and check again.

Edit: confirmed as far back as 3.1b2.
[Galaxy S II Original Android Development] MaKTaiL:
I just got a random reboot while using 3.1. The screen turned off and it wouldn't turn up anymore. Then the phone rebooted.
[Galaxy S II Original Android Development] lfabresm:
well.... I bricked my phone because of v3.1rc6

before the warning was public, I got the camera app error, then I think "a wipe should fix this" ... damn it :(

now looking for a "unbricking" service... no luck so far in my country... I'm wondering how hard could be to use a JTAG to unbrick my phone and how expensive is this.

Learned lesson: don't try any beta or RC kernel

In the meantime back to my old Motorola Milestone... I can do phone calls! :D

Wow. Glad I didn't hop onto RC6 and waited. That's like... Horrible.
[Galaxy S II Original Android Development] beston94:
But the services are usually 30 quid or so.

Have a good day :] Hope you get it fixed!!
[Galaxy S II Original Android Development] sefrcoko:
I think the real lesson is to wait for reviews to be posted if we are worried about something going wrong. Hard to develop if no one uses betas and rc's. ;)

[Galaxy S II Original Android Development] gendis1979:
It seems good 3.1

Installed this morning: about 12% of battery consumption with a normal use and a couple of hour with data synchronization activated
[Galaxy S II Original Android Development] gaui:
Is there still risk of bricking with 3.1? Should I before installing another ROM (full wipe), install another kernel?
[Galaxy S II Original Android Development] AvRS:
No! I'm sorry but how many more confirmations do people need I've seen Gok post more than he's had to about this. If you're not comfortable flash something else but please stop asking. It's safe but nothing is 100% safe when flashing.
[Galaxy S II Original Android Development] sm.vassallo:
No you should be fine, i use it with the sensation 3.4 rom. :D
[Galaxy S II Original Android Development] Pigmachine:
Since the 3.1 will be 3.11.. can we who use the old mounting system inherit the 3.1 name? As an ending of being on a RC even though it's a full version :)

BTW my front camera FC's too and I have the latest RC6.. and it FC'd on 3.1 too (running on resurrection remix 1.5)
[Galaxy S II Original Android Development] lfabresm:

Obviously spoken from a person who doesn't now own an expensive paperweight... Yes we all know the risks of flashing blah, blah etc, but like me it seems that most people were doing nothing more risky than a data wipe in CWM, something I have done dozens of times previously. I think we do have reason to feel a little aggrieved! :mad:
[Galaxy S II Original Android Development] gokhanmoral:
you are just at the right place.

checkout initramfs3 and siyahkernel3 repos from github.com/gokhanmoral

switch to m250l-3.0.y branch

compile it

and then try to wipe after flashing a rom or restoring nandroid backup several times..

if you are lucky you'll have a bricked device.

it is very important that you use m250l-3.0.y. if you use any of update4-* branches you won't be able to do it.
