[Q] instability because of kernel? - Galaxy S II Q&A, Help & Troubleshooting

Hi all,
Until recently I have been having very unstable results with my SGS2 (gt-i9100), every time the phone would freeze, overheat, use most of the battery in 2 seconds (figuratively speaking that is) or rebooting itself.
Some people on this forum told me to try a different kernel or roms, something I did and well no real improvement, I tried combinations of ressurection remix, omega and kernels such as siyah and dorimanx (I tried more but these are the ones I still remember by name)
Luckily (or unfortunately) I love my phone and android so I didn't really want to change hardware.
Couple of weeks ago, I figured that maybe I should try yet another rom and... SUCCESS!!
Ever since flashing AOKP milestone 1 everything is the way it should be (well to be honest first thing I always do when getting a new phone is rooting it and getting a new rom, so I am not sure how "normal" out of the box operating of an android is :silly
So basically my question to you is:
does the instability have anything to do with the kernel? currently using 3.0.31-cm-00008 (which incidentally, is that CyanogenMod?)
if it is related to the kernel, anyone has any suggestions to make dorimanx/siyah work (as they seem to be pretty popular here on xda, I'm guessing it has more to do with me)
and less kernel related, if a rom is AOKP based (or CM or whatever), does that mean that this rom has all the bugs from the base + the things the specific rom has?
Thanks!

1. May or may not be, usually it's kernel related, yeah that is the usual kernel made for CyanogenMod
2. The latest dorimanx does work fine with xwlsn and so does the latest siyah for xwlss.
3. An AOKP rom has different frameworks and usually is more buggier than stock rom, because of closed source codes (blame Samsung) several features are disabled or improperly functioning.

[Q] Stock rom instability

Good morning everyone
Seems to be that my GSII has serious issues running his stock rom (continuous reboots, not-working 3g etc.). I tried several factory resets, but nothing worked 100% . CM fixes some of my problems, but the only full-working custom rom is MIUI, that seems to be stable and very neat. Despite that I still prefer the custom rom (yes I'm probably insane), or a more traditional one like CM and I really would like to understand what kind of problems can generate such a massive amount of errors and reboots.
Could be a hardware problem? MIUI works fine, I can't explain why I still got problems with other ROMs.
Sorry for my bad English, thanks in advance
Without telling us the version of the stock rom you are using, we can never give you any answers.
I'm currently using
2.6.35.7-I9100XWKDD-CL161513 [email protected] #2 Kernel
Gingerbread.xwkj3 Build
That's not the original stock ROM, just one I found (here on xda I guess...)
Is there some kind of hardware-check I can run by myself, just for exclude manifacturing defects?
if you want to check to exclude hardware defects, u could go to the dialer and press *#0*# .. it will give u a list of tests which allows u to pinpoint any hardware defects ( if it exists) .... but if the problem is with the 3g, you could reflash your modem..
Initial problems were strictly connected with 3g's use, after a few hours of use i've noticed slowdowns using sms, then it started crashing and random rebooting. That's the same reason why I initially switched from original ROM to CM. I mean, I know that Samsung's ROM is not the best one at all, but I can't figure why it's so instable on my device.

As that the oldest stock rom try a newer one .
jje
Updating: now my GSII works with latest stable Cyanogen, except for the 3g that's still not working. Should I reflash modem, as suggested by roophz?
That old kernel is known to cause random reboots.
Update to a newer stock rom.

Update 2: I switched from the old stock rom to the latest cyanogen stable version, then to a newer stock rom and then back to MIUI again. Still no life signals from 3g.
How is that possible?

Curiosity, confusion, I don't really understand, some help please?

Hello everyone.
It has been a long time since I was here looking at things.
I'd like to say that there is great progress and Kutos to those who are doing the work.
-------------------------------------------
Anyone have any good/bad experiences using the kernel I listed below?
And, I do not really want to overclock at the moment, Is there a way to edit the kernel to remove the changed CPU and battery management?
I tried to find a custom kernel that, without all these extra changes, allows a custom ROM, but I have had no luck yet...
(I do not want to shorten the life of my device in any way); unless it is safe?
------------------------------------------
I was thinking of using this kernel (which I want to put the unnecessary changes back to stock):
[KERNEL][CWM][Player 5.0][USA]Entropy's Daily Driver, 3/5/2012 (1.2 GHz OC)
-------------------------------------------
And I'm still deciding between these two roms:
1) [ROM] Eryigit-GB-2.3.6 G70ZCKPA Galaxy Player 5.0 For USA and INT (Rls:3.5) {UPDATED}
2) [ROM] Eryigit-GB-2.3.6 G70XXKPH Galaxy Player 5.0 For USA and INTERNATIONAL (Rls:1.5)
My problem is I do not really understand the differences between these rom versions other than the display.
Is that all that is different? the themes?
And I'm having trouble finding if this ROM can actually work the cameras, flash, Bluetooth, etc. or are things not working?
I tried looking for a "bugs" category, but I haven't seen one.
----------------------------------------------
Thank you for posting your experiences and such.
I'd jump right in and try the kernel and roms, but I really do not want to risk breaking anything, I kinda just want to do it right the first time and leave it.
--------------------------------------------
I mainly been looking because I read that Samsung is not planning any updates for my device and I figure I'd modify it now since I wont get the latest android for it.
My device:
Samsung Galaxy Player 5.0 Wifi USA version, WITHOUT mechanical home button...
You cant edit the kernel and off course its safe,everybodu is using them..but if you want you can down clock with some app but don't see why..on roms you mentioned everything works...difference is first has more futures like 14 button power menu etc..and second is basicy stock rom.
Alright bro. Entropy Kernel: You wont notice anything different in your Player if you flash it. It will only make it faster, but no UI changes. And the ROM you listed, use 3.5, Everything works. Again, more tweaks will make it faster. The ROM probably has some things changed in the UI but thats for the better. No bugs in that ROM. If you need help don't hesitate to PM me

Sorry I have been away for a while. College takes up all my time...lol
Thank you both for posting that. It verified everything I needed to know about the ROM and Kernel.
(I just want this to last if I overclock it with with the custom things, I do not feel like replacing a battery within the next couple years...lol).
Later on I will go find an odin or something along those lines and backup what I can from my device so I can hopefully go back to stock later if I ever needed to...
Hopefully I will be able to do it before the world ends in about 3 months. I will post here when I get to it.
I just recently bought a 32 GB MicroSD card for it. Its really nice as I can store everything in my phone now and its essentially my slate PC but its a phone, so I will need a time when I wont need to use it for school/work/navigation things for a while so I know its stable.

I had the exact same experience with my wife's phone that I bought of ebay. I even flashed a variety of RIL's (radio interface layers) and different modems. I'd never had the problem with my SGS3 before, and have hundred of different roms on it.
Anyway it seemed to be a kernel issue and after trying ever combination possible I found that wifi would always work perfectly on any stock based rom or any CM based rom (assuming that hey used the CM kernel). It wouldn't even work on a CM rom if I flashed a different kernel such as Yank's, Boeffla or Googy.
Also at the time I trawled the net looking for answers and found one or two others that had the same issue, but could still use stock Sammy or CM. Strange... almost felt like it was an odd batch.

[Q] Best SIII 4.4 ROM or BTU?

Hi All
Long story short, my phone broke and samsung fixed it under warrantee. They returned it with the vodaphone 4.3 flavor OS which was bloated to bursting point with all the crap-ware they add. So naturally the phone was dead slow, which prompted me to flash it to the 4.3 BTU. The phone is quite fast now, but the updates don't work so I'm stuck with those dreaded initial 4.3 software bugs, wifi connectivity & battery drain to name just 2.
I'd like to know if there are any decent & stable 4.4 ROMs available? I have tried CM11 earlier this year, but that didn't work to well, it was quite buggy.
I'd love to be able to install the 4.4.x BTU, but as far as I can tell, it hasn't been released (yet?).
Advice would be great.
Thanks!

I never expirienced any strange bugs like eith new 4.3 uodates, try using some great custom 4.3 roms out here, like archidroid, neatrom, arhd etc. Just search and try, combine it with a custom kernel and your phone will be reborned.
4.4.x ism't and won't be released for s3, because, well, samsung is $#&*, but you have note2 4.4 ports, like QS kitkat Archiport, and s5 themed like Blekota etc. But these 4.4 ports are having graphical glitches which occur for some, for some not, but as I see, Lord Boeffla updated his Boeffla kernel and in new updates graphical glitches are gone, battery life is much better and wifi direct and screen mirroring are working.
So if you want best stability go with custom 4.3, if you want to test out the kitkat experience which should be good now if combined with Boeffla kernel then go with some 4.4 port.
And don't forget, best rom threads are not allowed and will be closed by moderator, you should try what xda world has to offer and then decide.

How do I load a custom kernel? I've only ever flashed with Odin and then that was just the ROM.
Just as a matter of interest, 4.4 has been released for the S3 on certain carriers.
Flash the kernel through your custom recovery.
Only the versions of the s3 which have 2gb of ram have kitkat..other versions do not including the international version

Just as Pulseuser mentioned, 4.4 is released only for i9305 LTE variant of s3.
About custom kernel, the easiest method is to root your phone using cf-autoroot, just google cf auto root and download the .tar.md5 for Odin for i9300 S3. Then when your phone is rooted download ROM Manager from playstore and install Clockwork Mod recovery, then reboot to the recovery via rom manager app and choose install zip from sdcard, fin your custom kernel/rom or whatever you want to flash and then tap yes and reboot, but first copy your custom kernel/rom on sdcard.
It is very easy, you even have tutorials on youtube on how to flash something via CWM recovery.

Dokdo ROM M440s

So as hectic as it was for me to find a perfect rom, for some reasons i couldnt find a lollipop one. i am currently using cm12.1+devil kernel (which is giving major FCs during installations of apk's and randoms for some reasons despite clean installs) as thats the only option i had other than dokdo that got discontinued and site/server everything is just down.
Can anyone please provide me file/link/mirror if possible?
i am to use s3 for next 2 weeks and i can really use a cm based lollipop rom, so if you're reading this and can, do leave a reply, thanks.
