Tester

Hello Everyone.

I have tested 1.2.4,

and It is totally stable. No problems at all.

On first run, its quite slow.. (dont worry, i pushed nitubhaskar for it with an heart attack)

then its stable.

I tested basic things, all seem to work fine.

So i will give it a +1 and wait eagerly for 1.2.5.

Nitubhaskar, Thank you for your wonderful work, and if you ever need a tested, please feel free to contact me anytime. I have something in mind for you. i will do it as soon as i can :)

Hi

Thank you for your work making this kernel, and then supporting us here.

I am on 1.2.4 Compact Kernel, and everything works fine, so far. Here is a battery use screen shot with this kernel. The phone shows it is intermittently awake, when it shouldn't be. Of course I noticed the battery doesn't seem affected, so am not even clear whether I should be concerned :)

I did make a swap of 64M while on this kernel and found I could not install anything. The phone restarts after trying to install an apk. I was installing the latest YouTube apk. So I just went back to being without swap and things are all normal. Installs happen normally too.

Kindly let me know your recommendations for swap on with this kernel, and any other relevant details.

Once again, thank you for your support and patience!

[Galaxy Y Duos S6102 Android Development] Xtreme666:
Hey,

armm i doubt this is something to do with kernel,

but anyways. i will tell you what i have done so far.

1) i have three partitions of my sd card.

2) i used swapper 2..

3) my swap is 256 mb.

my calculations of swap is, i make a logical choice actually.. we have 289 mb ram in this device, and looking at swap and swappiness, pushing more swap to sdcard will just make it slow, nothing else..

so i wanted to select between 128 and 256,, and i selected 256, coz its less then original ram sufficient enough to hold heavy apps.

and on my cell, everything is working like charm so far..

well actually was working, but forget about it..

so my suggestions for you, 1) less then 256 mb, 2) partition, 3) swapper 2..
[Galaxy Y Duos S6102 Android Development] arbayong:
No one said using a supported kernel automatically gives you swap. The kerne, I believe, merely optimises your use of swap partitions. No matter what kernel you use you must have a swap partition or swap file on your system. I have no need for swap on my phone so i have not tested it yet but i have experience using swap on ubuntu powered laptops.There are many threads about swap so people should search for more info on a good swap size and the best swappiness value to use. i believe the 256mb (and the reason given for it by Xtreme666) is good since since its slower to work from sdcards than from ram.
[Galaxy Y Duos S6102 Android Development] Deadly:
Guys.. as always.. i need help from you all to confirm that.. what i have written in first post for 1.2.4 version has those features.. well atleast tell me available cpu freq and governors and i/o schedulers.. please confirm that.. i want to keep this thread info properly updated..

and sorry for not doing it till now.. i was a bit lazy and bored to reformat that.. so, i apologise for making it harder for you guys..

I have reformatted the first page.. now.. so please do look into it.. well doing it stil,.. but i guess it will be done by the time you guys pop up here.. :)
[Galaxy Y Duos S6102 Android Development] arbayong:
Cpu freq: 832, 624, 468 and 312 mhz

Governors: turbodroid, battsaver, balanced, conservative, interactive, ondemand and performance.

I/o schedulers: noop, sio, vr and deadline
[Galaxy Y Duos S6102 Android Development] Deadly:
First of all, you need a kernel that has swap enabled in it to support swap functionality.. So, to say.. if you wan to use swap as a partition or as a file on sdcard.. you have to have a kernel which supports it.. this kernel does supports it.. all versions of them.. so no need to worry abouth that..

now, about the size, it depends on your needs andyour sdcard size and its class.. actually, if you have class 4 or less i would like to say, please dont use swap.. because it wont boost yuor device speed then.. but if you have good class sdcard and you want to have swap partition.. go ahead and create one..

size can be anything.. but i recommend to create something within 100-300 mb.. but u can createa 1 gb also.. that would be a total waste.. but if u can afford to waste space.. (if you have 16 gb card) then you can do that.. i am speaking in general here..

So , swapiness value./.. try varying it.. and see which one suits u better.. ususally around 20-60 is good.. try different values and play games.. you will see which is better.. its all try and see methods.. as everyones tastes and satisfaction level differs.. and the suggested app does do the job swapper2.. but to be frankly speaking this is my knowledge by reading many threads and users experience only,... i am sure i am correct here.. but i have personally not used swap on my phone.. i have used it on PC though..

and finally battery status showing phone awake issue.. can you provide me a log cat? i wonder why its happening? its because of some app.. not kernel issue.. as deep sleep is working.. otherwise you wouldnt get such straight line.. but i think some app is checking for updates/something.. so cant confirm without logcat..

and the app installation reboot issue.. yes i have seen that.. its not because of kernel.. try decompiling framework-res.apk and see if it has too many warnings aor such.. i think there is some stability issue with the apk.. not sure.. but i feel thats the issue.. so if u cant do it.. upload the framework-res.apk file of your rom.. and i will take a look at it once i get time..

and thanks for the compliments.. and keep supporting here :)
[Galaxy Y Duos S6102 Android Development] arbayong:
Yes I also thought an app was waking app the phone eg an app like yahoo mail app can do that. @Nitu decompiling framework res would be easy compiling is where problems come in. Apkmanager 5+ for windows is app of choice as all others failed even apkmanager for linux failed. He used my rom at time of restart issue. Best of of my knowledge he's 2nd to have that problem and the previous one was was resolved by repeat of with little intervention
[Galaxy Y Duos S6102 Android Development] Deadly:
Well.. That's what i meant.. Doing.it will tell what is wrong.. Im bit lazy when i type i skip words.. Also i prefer apktool than anything else.. Its much better..

[Galaxy Y Duos S6102 Android Development] arbayong:
At Nitu, trust me here I tried different versions of apktool for both linux and windows but they all failed at commpile stage eventhough I properly installed system files. They worked fone for some system files but not edited framework-res.apk. I know its strange is apkmanager is basically a front end for apktool. Lots of guys had same problem . Search forum or ask hell_lock. It took me nearly 2 weeks to successfully compile edited framework-res.apk and I wuse windows just to compile this file otherwise I am an ubuntu guy

Hi, everyone.. sorry for no updates yet...

I was busy writing this guide thread.. [GUIDE]Don't know something? Check here first!

Its a big guide and takes too much writing.. so its taking all my time.. now I have exams.. I will get back to kernel building after this week.. the guide itself needs more writing.. as still 3-4 more guides need to be written..

Do check the guide thread.. and if you have good suggestions to improve it.. PM me.. I have written it for all type users.. hope it helps you all..

So please don't mind.. I will release a new kernel which will have better features hopefully..

[Galaxy Y Duos S6102 Android Development] Deadly:
Sorry I am busy due to exams & I forgot that I told I will help in 30 mins..

Anyway.. since you said you have used other Samsung phones... I will assume you know how to get to recovery or Odin mode.. but AFAIK.. you should be able to go to recovery or download mode..

Can you please tell which rom and kernel you are on?

Because seems to me you are on stock.. if so you should be able to go to recovery without problems..

Switch off phone.. wait for vibration confirmation..

Now, Try holding power + home + volume up button and release it after you see Samsung logo.. wait for 5 seconds.. you should see recovery now..

If not.. then please install a new stock rom using Odin.. you should use volume down instead of up to get to download mode..

If you are not able to go to download mode also, I suggest you to visit service center and ask them for firmware update.. say, through kies its failing..

Or use USB jig which will force download mode..

Tested V 1.2.4, found very stable and useful (I just used the ondemand governor by now).

But without rooting the phone, I thought that the conservative governor was the default, instead I always saw 832Mhz, and when I installed No-frills cpu app, the governor choice was set to bcm21553.

Thank you!

Hello Deadly,

Could you add support for BLN in your kernel?

BLN uses the backlight of hardware keys, which in our case are the keyboard keys, as notification LEDs.

Thanks.
[Galaxy Y Duos S6102 Android Development] Deadly:
Honestly speaking.. I have seen it.. I mean the values and such related to it.. but, problem is.. I can't test it myself.. as in duos phone.. there is no back light on keys.. so if I implement on pro duos and if keys malfunction.. I can't help.. I mean , I never want to ask others for testing without I doing it on my phone first.. so, I will think about it.. and if you are ready to test it.. I will send it in pm if I do try it..

Thank you
[Galaxy Y Duos S6102 Android Development] dantech:
Dear developers,

I have found some problem with v1.24. Normally I use official kernel and rom XLF1 or XLL1 (Poland) but one has huge battery consumption. That is the reason I try to use your kernel. After kernel update onto v1.24 my IMEI disappeared. The only way to see proper IMEI is to restore original system by means of Odin. The phone works properly. I have tried this trick twice succesfully. I have a few different (I mean ways) efs backups for sure. But I would like to see my IMEI by *#06# code. By the way... When I use Galaxy Toolbox applikaction, I see proper IMEI under "device information" menu. So, it look that efs and IMEI are valid but not shown properly.
[Galaxy Y Duos S6102 Android Development] Deadly:
@dantech.. can you tell me what happens when you try *#06#

In dialer tab?

Because it should show.. in my phone its appearing..

Hi,

After *#06# IMEI field is blank - nothing inside When I try to see IMEI through Settings /About IMEI field is "unknown". Also MAC adresses of WIFI and bluetooth seem to be different than in fact. But, like I said earlier, IMEI shown througt Galaxy Toolbok application (from Google Play) is proper.

Of course this is dual sim and problem concerns both sim cards. The phon seems to work normally even with IMEI problem. The only way to restore IMEI and MACs is to use Odin and original firmware. I have a few different backups of my boot and efs.

Maybe I should use v1 at the beginning and then the latest kernel

BTW. Power consumption with your kernel and no-frills application is near zero :) Excelent in the other words.
[Galaxy Y Duos S6102 Android Development] Deadly:
Which ROM are you on?

This should not happen... The last time i heard something like this is here.. Check this link
[Galaxy Y Duos S6102 Android Development] dantech:
At the moment I use official for Poland XXLL1 rom version. It seems that one is quite fresh and newer than XXLF1. I do not see anything about XXLL1 in the internet.
[Galaxy Y Duos S6102 Android Development] Deadly:
can you flash older firmware version and then flash this kernel and see whether it works??

Because till date no such report came.. well, also, try other versions 1.2.2 and see if that works?
[Galaxy Y Duos S6102 Android Development] dantech:
Yes, of course I shall try v1 and v1.22. I need several minutes time and I shall be back here with report. At the beginning I restore XXLF1 and try to use v1 than v1.22 than v1.24. At the and I shall allow to download through internet the latest XXLL1 update

---------- Post added at 11:31 AM ---------- Previous post was at 11:15 AM ----------

Reports:

- XXLF1 restored, IMEIs and MACs are properly shown

- kernel v1.0 installed, IMEIs and MACs are proper !!!

- kernel v1.22 and v1.24 installed, IMEI and MACs are still proper!!!

Next tests results within a few minutes time... Time to allow automatic updates and make update onto XXLL1

Ooooops. When updated, just after first reboot I have "Cannot update ,try again with Kies or go to service center" (translated from polish). It looks that XXLL1 is not compatible with your kernel.

So, resuming

When we want to use custom kernel it is necessary to have XXLF1 rom. Unfortunatelly (or not :)) XXLL1 was released shot time ago. There is nothing about this fact in the internet. Check your rom release before kernel update. When automatic updates are done (probably you have XXLL1 now) and you will update kernel onto custom kernel, you won't see proper IMEIs and MACs. The only way to restore IMEIs and MACs showing is to restore original XXLF1 via Odin. You should disable automatic updates. Then you can replace kernel properly.

I have verified issue with XXLF2 - works well.

Click "Thanks meter" :)
[Galaxy Y Duos S6102 Android Development] Deadly:
No, Firmware over the air Updates cannot be installed if you have custom kernel or rom or rooted..
[Galaxy Y Duos S6102 Android Development] dantech:
Is it possible do update system via Kies when custom rom used and rooted?

What will happen when Kies detects XXLL1 and I use XXLF2 with custom rom?
[Galaxy Y Duos S6102 Android Development] Deadly:
kies won't detect your phone afaik... so you won't get an update option.. its better to be on stock and unrooted to do update via kies or FOTA.. using Odin to update firmware is best & safe method..

At the moment I use original XXLF2 and custom v1.24 + root. New XXLL1 is detected by Kies and OTA. When I tried to update via OTA then update was downloaded, phone rebooted and there was the message "Cannot update, ble, ble, ble".

Will it be the same with Kies?
[Galaxy Y Duos S6102 Android Development] Deadly:
Well, that's the thing... since you are on stock rom.. kies is detecting it.. but update will fail I think..

But I cant tell you for sure.. because I hate kies and never updated from it.. as it doesn't have resume option while downloading .. its nearly impossible to update from it..

So, without personal experience I can't be sure.. but it won't work as far as I can tell..

But if you have patience and firmware to install from Odin.. then you can try..

Hmmmm. It means that custom kernel XLF2 works with earlier kernels also. custom kernel work with the latest XLL1 rom but there are problems with IMEI and MACs.

---------- Post added at 09:15 PM ---------- Previous post was at 09:09 PM ----------

Like we know your custom kernel is based on XLF2 kernel. Like we know also, there are problems with IMEI and MACs whilst using official XLL1 rom and custom kernel XLF2. So, I think that new custom kernel v2.xx (shall we say) should be released by you to work with the latest official XLL2 rom.

Am I right?
[Galaxy Y Duos S6102 Android Development] Deadly:
Re: [NEW][KERNEL][GT-B5512] Compact V 1.2.4 for Samsung Galaxy Y PRO DUOS

OK.. first of all, the kernel is not actually linked to firmware updates... what happens is.. they release a source code which we use to build a kernel..

So, after the release if there are any updates to kernel source files.. they usually release updated version of it..

But, you can't tell whether its from firmware version "xxxx" or firmware version "yyyy"

It should work.. let me see when time comes..

Thanks for clarification :thumbup:
