Installed kernel V1.2 but it was constant rebooting. Have flashed V1.0 and this seems stable.

Will gladly try a update of the kernel because it seemed al lot faster!
[Galaxy Y Duos S6102 Android Development] Deadly:
well the next version is much better.. so please wait 10 more mins .. its getting compiled.. so will release it soon..

NEW Version... Compact 1.2.2

Download link removed.. i think this will be more stable..

[Galaxy Y Duos S6102 Android Development] arbayong:
kernelversion 1.2.2 now stable on my phone!!!

edit: kernelver1 screenshots here

kernelver1.2.2 screenies here

NB: flashing the zip file of kernel1.2.2 gives same problem. if i unpack the zip and flash boot.img via kernelflasher, everything works well. kernel is highly stable

These screenies depict cpu freqency which were accidentally no added to the previously uploaded screenies for kernel ver 1.2.2

Man its bricked

Man, Your kernel totally bricked my cellphone..

I can go into recovery mode, but none of the keys work..

now what to do?

i am trying to restore it using odin
[Galaxy Y Duos S6102 Android Development] Deadly:
yup.. use odin.. it works.. i have given details in 4th post of this thread in first page for odin installation procedure.. can you please tell me what u did ? i mean method u sued to install? so that i can help..

Also see above post by arbong.. i think thats the same solution for you.. sorry for the soft brick.. :(
[Galaxy Y Duos S6102 Android Development] smartxtreme:
Screwed

Well

1) i cannot enter odin downloader mode.

It always enters the recovery and as i cannot operate any key, i cannot do anything

what i did?

1) downloaded kernel version 1.2.1

2) downloaded the CWM

3) downloaded KernelBackup

backed up the kernel

then tried installing kernel.. and rebotted as it said.

then it got stuck in reboot look.

so i removed the bettery, entered the recovery mode.. and no keys are getting operated.

then i came to my windows, (i am a linux user), loaded odin, loaded the backup up kernel. (lucky i got another samsung, so i could transfer files using it as card reader.)

and when i tried to enter odin mode, i noticed it stuck in recovery.

so now, i am waiting for your response so that i can enter download mode.

;( ;( ;( ;( ;( ;( ;( ;(

I dont want to give my mobile to samsung gallery people. not because they charge, but coz they keep the cellphone there for days...

EDIT:

you know what man, i dont care for my data.. coz i am synced..

I have my stock rom/kernel and i got many many other things to get me back on track..

i just need to get out of recovery mode and enter odin download mode

Man you on gtalk/skype/IRC?

see, i am not going to give up :) even if i brick my phone, as soon as it restored, i am trying the kernel again..

so looks like you got one live tester..

so let me know..
[Galaxy Y Duos S6102 Android Development] Deadly:
ok.. got it.. so.. i think this should work... do this.. remove battery.. put it back.. as soon as you switch on.. press and hold volume down+power button + home button.. it should work..

ok.. come to irc..
[Galaxy Y Duos S6102 Android Development] arbayong:
Yes. This new method works. That is how I entered odin mode.vol down+home+power button never fails.

Testing

I'm using you kernel, version 1.2.2, and the HatyonRom, from @arbayong!

First i have problems to flash the kernel... then I extracted the boot.img from the update.zip and used the @Milan.SIS KernelFlasherV2 and it worked!

Now I'm giving a try... changed the governors and the IOScheduler... btw... we can't do overclock or undervolt? I didn't see not specified...

Another info... app2sd is possible, right? because ext2 (3 & 4) is supported and the init.d too.... am I right?

How do you recommend doing app2sd? and about swap?

If something go wrong I'll report to you! =)

And thank you for the good job with this cellphone!
[Galaxy Y Duos S6102 Android Development] Carlovn:
Allright as promised my report of the kernel with stock ROM:

I have to quote here because I'm not using the phone myself: "Man, my phone is faster than Usain BOlt right now!"

Had not one single reboot, freeze or anything over the weekend so you could say this kernel is stable!

I'm going to try to flash the ROM today because there is new instructions to get around the not booting problem.

Would love some small guide on how to use SWAP to extend the phone storage!

And also: is the Hatyon ROM 4ext compatible? Because on my owne phone that really speeded things up a lot.

Thanks for the great work guys! You really made this phone a lot better!

BTW good luck with your exams man!

Thanks for the report..

Tutorial link There are amny tutorials for the one you asked.. please do a search on xda.. and you wil find many.. Note: please dont do the 2nd step in the tutorial link i gave... as it is for y duos he has given.. and you will brick your device as your is 5512 phone and that kernel in tutorial is for 6102.. if you are speaking about converting data and system to ext4.. any rom is compatible with ext4.. its kernel that should support ext4.. currently

mine i have not checked.. it should support though..

Your welcome.. and thanks for the report.. always needed..
[Galaxy Y Duos S6102 Android Development] arbayong:
@Nitubhaskar. I think you should edit istallation instructions and add kernel flashing boot.img and Millan.sis's kernel flasher as it seems to be the method that works flawlessly.

@rcbadiale. I believe you will need a swp parttiion on you sdcard. In ubuntu its easy to do. Put sdcard into laptop and use gparted to shrink the vfat partition from the end (not beginning) you can then format the free space as linux swap partition. Same method can be used to create another partition (ext3) for app2sd. I don't know about windows pc. Hope it helps.

Hey thanks for reminding me about this.. And i saw my error now.. Sorry for this.. I had made a small error in updater-script which caused the problem..

[Galaxy Y Duos S6102 Android Development] rcbadiale:
I have 2 reports to do:

1- I can't make app2sd (ext) work yet... I tried the tutorial you posted here and I tried an old way... the same I used on my old Motorola Milestone, and I've no success...

2- I just realised now, I don't know why it happen, but my phone stuck in the lockscreen after a reboot... I've to remove the battery and boot again to work! It's weird!

And I have two things successful tested... swap partition and mount EXT3 filesystem!

My last edit: Now the app2sd and the swap is working... simpler than I though... just partitioned the SDCard (higher class is better) than open a terminal or use ADB, use the command: 'a2sd' than wait... he will make the ap2sd work and the swap partition... if you have a class 10 card you can move the dalvik-cache too... use the command: 'a2sd cachesdreset' and it's done! First i had 64MB used... now it's just 6.6MB used...
[Galaxy Y Duos S6102 Android Development] Deadly:
You dont have to remove battery.. at any time when phone is on.. 3 button combo works.. so just keep on pressing volume up + home button + power button until u see blank/black screen.. then release.. it will reboot..

How much time did u wait at lockscreen? Which rom are you using? Are using any 3rd party lockscreen app?

Which version of kernel are u using? Did u flash kernel from cwm?

Thanks Nitu, i thought you added some OC feature for galaxy y duos kernel. i was hoping to find OC in our kernel ver 1.2.3. will OC upto 900mhz be feasible?

going to test 1.2.3 but please add download link to downloads section too. also the change log should be on first page as well.

well, nothing to hide. Just testing something i learned from Nitubhaskar today, lol!
[Galaxy Y Duos S6102 Android Development] Deadly:
nope... many things will be bit slow here.. as a safety measure.. as i am not having this device.. i dont want any new users to brick the device by trying untested versions..

So, until i get confirmation that it works.. Download links or first page are not updated.. and i want 100% confirmation .. Also the OC is not totally stable on my device and it needs lot more work on it and testing.. Until it becomes stable i dont want to try it here.. I release only reliable versions here.. i mean i should be sure they wont brick device while i release here as i cant test it myself..

for y duos i can try first then upload.. so that if it bricks it will be mine.. not others :)

So, sorry.. OC for pro duos will be bit late.. and OC for y duos itself is not 100% at the moment..

PS: your testing worked ;)
[Galaxy Y Duos S6102 Android Development] arbayong:

theres that bug confirmed the battary life is almost the same as i keep my phone in 156mhz range and deep sleep
[Galaxy Y Duos S6102 Android Development] arbayong:
Hard to talk about battery as am tethered via usb most of the time. For the bug I suspect the i/o schedulers as when I change to say vr with intellidem governor I don't have sleep issues.
[Galaxy Y Duos S6102 Android Development] jkananda:
Hi I am using 1.2.3 and find that the phone has been intermittently awake during the night, when I was not using. Shows up in the battery usage graph.

Also sometimes it hangs on trying to swipe open - the screen remains dark, the keypad lights up, and it is off the network, but heats up. Quite frequently, actually!

Seems everyone is awaiting arbayong's response huhn? Flashed successfully few hours ago. Min cpu freq changed from 156 to 312 mhz. Nitu some of us want the lower freq. Can I get a personal 1.2.4 build with 156mhz min freq?
[Galaxy Y Duos S6102 Android Development] Deadly:
i will add more freq.. but since 1.2.3 had some issues.. i wanted to try something in 1.2.4.. seems everything is working?? any issues?
[Galaxy Y Duos S6102 Android Development] ksameh:
1.2.3 gave me several sleep of death using different governors. usually once every 24 hours might be due to lower frequency.

Will try now version and feed back.

---------- Post added at 10:30 PM ---------- Previous post was at 09:50 PM ----------

I installed 1.2.4 without trouble. Wiped cache and dalvik.

Noticed that you added some governors and removed others.

One observation over all versions is the lack of stock cfq stock scheduler.

I will feed back on the sleep of death issue in a day or so a after having the min frequency at 312.

Thanks very much for the good kernel. Good enough for a daily driver.the only custom one for the pro.
[Galaxy Y Duos S6102 Android Development] arbayong:
Bcm..... is stock governor and I believe noop is stock i/o scheduler.
[Galaxy Y Duos S6102 Android Development] ksameh:
I think you might be mistaken.

I installed Stock kernel and checked with set CPU. The stock scheduler is cfq.

Not that an complaining. It is an entry level device and schedulers would not make huge difference in performance any ways.
[Galaxy Y Duos S6102 Android Development] arbayong:
Well I have till date never seen or heard of that i/o scheduler (cfq).
[Galaxy Y Duos S6102 Android Development] Deadly:
Actually.. it shouldn't be..

I mean in stock kernel Samsung uses noop scheduler.. I'm not having your device.. so can't comment on that..

But usually it will be noop as default..

I don't want to use cfq.. as it is mainly made for desktop users in linux not for small memory devices.. I'm on mobile so can't give details.. I will give info about cfq later.. its noop that is default in galaxy y duos..

Sent from the MUST have app!

Actually I'm still experimenting with governors.. I want to select best working ones.. so with you all giving feedback .. I can decide better..

Also I will add freq in next version..

And I want to make some more tweaks.. so will release beta versions after 1.2.5.. but if it gives problems you can revert back to 1.2.5.. I need some testers who are available atleast twice a day on xda..
[Galaxy Y Duos S6102 Android Development] arbayong:
Am available at least twice a day.
[Galaxy Y Duos S6102 Android Development] ksameh:
Well.

I tried all of the governors except tyrbodroid and they seem to be functioning the way they should.

As for the 150 MHz frequency option it seems that it was causing my device to sleep of death on 1.2.4. I would recommend to remove it for that reason and keep the lowest at 312 mhz. Of course battery life with the 150 MHz was super if the Governor used it. But at the expense of an sod.

As for the scheduler set CPU might have miss read the cfq scheduler on my device.

All said v1.2.5 seems to be running well on my device. Am using interactive Governor and sio scheduler for the past day and all is stable..
[Galaxy Y Duos S6102 Android Development] Deadly:
Thanks for the feedback.. but i think you are getting confused with versions!

V1.2.5 is not released yet lol... you are using 1.2.4 and 1.2.3 is the one with sleep errors.. its not because of 156.. it was because of some tweaks i made to extend battery.. well, it didnt go as planned.. anyway 156 was working in 1.2.2 you can try that.. and its not causing the wake issue..

[Galaxy Y Duos S6102 Android Development] ksameh:
