no. AFAIK, every maintained rom incorporated fpbug fix already. it looks like your hardware is busted. i've seen other S2s with exactly the same hardware defect, sorry. you can get a new motherboard for your phone in aliexpress for about $25, i know one person who got one and it worked fine. of course, it'd be better to just change your phone. take a look at the elephone P8000, its quite cheap, but make sure the frequencies are compatible with your operator!

Wow I thought this kernel is 4.x :D Too good to be true... It was Android 4.x not kernel.
[Galaxy S II Android Development] KiranP23:
Does this kernel work with stock S2 i9100 T rooted with stock recovery ?

or kindly provide LINK which recovery i need to flash ?
[Galaxy S II Android Development] avispi11:
I guess that explains everything now because few weeks ago I fell into a river with the phone in my pocket :rolleyes: , got it wet and probably the hardware kinda got busted. Hmm time for a new phone I guess then.
[Galaxy S II Android Development] Lanchon:
oh that sucks!

backup anything of value.

open it up asap! removed everything. get the mainboard out. remove the camera from the mainboard. if you can also remove the rf shields from the board. give the board a nice wash in alcohol. very gently scrub it with an old toothbrush. maybe repeat the process. also wash the edge connector (just that) of the camera in alcohol if dirty. let it completely dry.

the board has a small battery. if it is leaking, remove it. dont bust anything while removing the batt! the phone works without it.

do this asap!
[Galaxy S II Android Development] avispi11:
So this procedure will help save my phone?
[Galaxy S II Android Development] Lanchon:
it might, if the problem is crap deposited on the board or some redox compounds that u can remove.
[Galaxy S II Android Development] Drakmon:
Hi, so I know this thread is pretty old now and may not get a response, but I thought I'd post a query here before making a new thread (Don't want to spam up the boards). I've got an s2 I've firmware upgraded using cm12.1S (CYANOGEN OS 12.1S V.1.0-i9100)

& my kernel version 3.0.64(3.0.64-CM-g7e7a10d) and even know it's been posted that further updates from the CM11 + would contain the fix, I seem to be suffering from these exact same symptoms as the FPBug produces & keep being pointed to this thread when researching.

I was wondering if a smarter and more versed person than I could give me some troubleshooting tips & help me figure out what this issue is, as before I moved up to lollipop my system was fine.

Thanks in advance!
[Galaxy S II Android Development] Lanchon:
yes, you are not supposed to spam old threads!

this thread is about an (obsolete) kernel you are not using so you are fully off-topic here. please post in the right thread.
[Galaxy S II Android Development] GeeckoDev:
No, it's not flashable. It's the zipped source code of the kernel patch.
[Galaxy S II Android Development] stoneh:
Thank you very much for your hardwork！@Lanchon
[Galaxy S II Android Development] Vidura Dissanayake:
well I flashed kernel+musicfix+cm11 snapshot but havent got much battery life than cm11 original kernel..so back to sammy..hope final release will give some satisfaction :)
[Galaxy S II Android Development] zeitferne:
If you flashed in that order (i.e. CM11 after kernel) then you have overwritten Lanchon's kernel with the default CM one.

[Galaxy S II Android Development] ahmedelhofy:
OK, I'm back on CM11 once again, I missed this buggy as hell ROM [emoji1]

Flashed CM11 1812 nightly + FPBug kernel V1

So far so good.... I'll let you how everything goes in a few days....
[Galaxy S II Android Development] Sir_Toby:
Doesn't work for me.

I have SpiritROM 4.4.4-v1.7-20141112 and came from Apolo 7.1. After first reboot, everything works fine, after second reboot no RIL, no ask for PIN, no IMEI. normal backup (without restoring EFS) works fine... :confused:
[Galaxy S II Android Development] ahmedelhofy:
This wasn't made to work on other ROMs (yet I think)... Do use you will have to be running CM11 M12 or 1812 or 1712 nightlies....
[Galaxy S II Android Development] Lanchon:
that is correct!

WOW!! im amazed! :) is it not clear from the OP that you should NOT flash the music bug fix with this kernel???

i mean the FAQ isnt long, it has 1 damn question lol!!! :)
[Galaxy S II Android Development] Lanchon:
aaaggghhhhhh!!!!!! :eek:

/me tweaks and spasms

this is a CM kernel people!! :)
[Galaxy S II Android Development] Sir_Toby:
Yeah, I know.

But Apolo also isn't especially for SpiritRom, but for CM11; so i thought I could give it a try ;) Spirit is based on CM11, afaik.

Flashed it again, after I had some other problems. At the moment it runs very stable, the issue described above didn't repeat, seemed to be related to frequent flashing and rebooting. I can give an update after a few days of use, if you want :)

Initial observation :

** The phone is not getting hot as it used to get.... I was used to the phone getting hot at its back (especially in the upper part ) when surfing web on 3G... It doesn't seem to heat that much now...

** Used 5 different tabs on chrome, all of them were not mobile optimized sites... And the phone didn't hang/freeze at all.. Was used to having problems with Chrome before...

For Battery performance & overall system performance it's still too early to judge...

Anyway, Great Job [MENTION=4141005]Lanchon[/MENTION] , You're awesome, you're with out a device, and doing all of this... Can't even think of what you gonna when you get you're friend's old device .... Hopefully we get official omni 5.0 now...
[Galaxy S II Android Development] Lanchon:
checkout the CM kernel, apply my patches, u r done!
[Galaxy S II Android Development] Acid0057:
Same experiences here. I'm on Dec 19th nightly with the corresponding kernel. Battery life good but I've only been using it for a day.

Some of us aren't programmers but enthusiasts or power users, like myself. I have no programming experience and definitely no github or kernel programming. That's why I love xda, we're all at different levels but we produce some awesome stuff.

I'm always willing to test and the s2 is my daily driver.

The one your looking for from the Android file host link in the original post is kernel-Lanchon-FPBug-20141218-cm-11-20141115-SNAPSHOT-M12-i9100.zip

Now flash that after flashing the m12 Rom. Or you can just flash the kernel only if your daughters phone is already running cm 11 m12 on a Galaxy s2 gt-i9100.

I installed this kernel (kernel-Lanchon-FPBug-20141218-cm-11-20141218-NIGHTLY-i9100.zip) on my I9100 which runs the latest SlimSaber. The wifi absolutly not works and the heating is present. Is this kernel only for the standard official CM11?
[Galaxy S II Android Development] Zile995:
Only for CM11. ;)

Much appreciated Lanchon. I have an SG2 and am using Markox89's custom CM based rom (latest version 201412220) so that I can use screen mirroring then flashed your FPBug kernel 20141218 for the i9100 and you have just made my hour and a bit commute to work a lot more appealing :) No sudden stops on my music players (I have 2 installed and both work fine now!!)

Not brave enough to try the trim kernels as I have repartioned my phone in the past to fit the apps on it I want as I have no sdcard. Good work - hope you have a good christmas. Thanks sooooo much :)

[Galaxy S II Android Development] Lanchon:
why not?? do it! there's no problem with repartitioning, in fact its recommended
[Galaxy S II Android Development] JimboAccy:
Oh I must have misread it - I thought it said somewhere there is a problem with the 'preload' if you have partitioned your phone (I have split my phone into 2 8GB partitions and I think that reduced the preload partition) I will have a re-read and check it. If I do it, I will let you know the outcome with screenshots.

The bug report is actually linked in the forum thread, it is here: CYAN-3877. I have posted the news of the fix there and will submit a patchset but, just to be sure, I will wait a bit longer for [MENTION=5145944]GeeckoDev[/MENTION], who reported a problem with my patch at the N7000 (Note 1) to answer this (it's Christmas after all, so I can't expect him to monitor XDA all the time). From what I understand, the problems are only there when applying the Patch to a (more or less) original Samsung kernel as opposed to a CyanogenMod or OmniROM one. but since the smdk4412 kernel to which this patch would be applied is used for many devices (at least Galaxy S2/i9100, S3/i9300, Note1/N7000, Note2/N7100) and I can only test the S2, I would would rather be safe than sorry.
