S2 Wifi Problem?!?! - Galaxy S II Q&A, Help & Troubleshooting

Hi guys, I was wondering someone could help me as I am noob in this area.
The thing is my Galaxy S2 I9100 was normally running 4.1.2 android and everything was great until sudden wifi connectivity problem. My Wifi won't turn on, keeps turning on but then just keeps it off and trying on and on. I used Google to help me out and there it says it has to do something with bad kernel .They mention some Siyah kernel as a solution.As I am already familiar with flashing, installing custom ROMs, I updated to CM13 (6.0.1) but couldn't install GApps through CWM 6.0.4.5 because of a small partition. Still my wifi problem occured, and I saw it has nothing to do with the ROM but kernel itself.
MY MAIN PROBLEM:
Can someone write instructions for a best package of KERNEL, RECOVERY and ROM that will fit together with no problems, preferably that Siyah kernel for my wifi problem and working partition for increase in internal storage for apps so i can install at least nano GApps?

Hi,
If you updated the ROM, then you also changed the kernel as the kernel comes with the ROM.
Try going back to full stock ROM, flashing via ODIN. This way, we can diagnose if it is hardware problem or software.

Does your device have a valid IMEI? If it doesn't, your efs partition may have been corrupted.
If it is still valid, it is likely that you are experiencing hardware failure. Switching between ROMs or Kernels will not help in this case. I'm afraid I am out of ideas other than replacing your device or buying a new motherboard.

I dialed *#06# and it says my IMEI is : 353824059632022 / 01 Is that valid IMEI?
Can I try this for myself: http://www.selftechgenius.com/how-t...nvalid-argument-in-all-samsung-galaxy-phones/

Your IMEI is valid.
That last thing I can think of is to try this kernel (even though I said that changing might not make a difference):
[PhilZ-cwm6][i9100/P] Stock Kernel+CWM6+Root+exFAT+NTFS-MS3
If the issue still exists, you have a hardware problem.

Although re-flashing stock ROM did good job (if wifi somehow stops,just need to restart phone), with this kernel for JB now I have no problem. Thanks mate !

Hello everyone i faced the same problem and solved it by an app called wifi fix which is made by amid M Geha

[Q] Unknown baseband version and IMEI, doesn't detect SIM

Hello everyone,
I went from being rooted on stock ROM:
Android version 2.3.5,
Baseband version XXKI4,
Kernel version [email protected] #4,
Build number GINGERBREAD.XWKI8.
And then I flashed N.E.A.K. Kernel for I9100 (v1.4x).
I rebooted the phone and it's not detecting my SIM card, the baseband version is unknown and so is the IMEI number.
I have searched and read numerous threads but I couldn't find clear instructions - I don't want to screw up my phone further by doing panicked acts, so therefore I ask you people for advice.
Thanks in advance!
strange!so you should root again,so maybe is the solution
Just flash a different kernel and flash neak again. Usually this happens to me when flashing kernels, but it only lasts a few seconds.
Sent from my GT-I9100 using XDA
Some people prefer using scripts to clear out crap from old kernels that may conflict with the new kernels. Especially important when going from say ICS back to ginger.
http://www.celica.talktalk.net/GalaxyS2/GS2BlitzerV1.6.zip
Run that from cwm, then install your new kernel - should be all sweet.
Thank you all!
@kitchy88, I will use that in the future! Although, the problem was solved when I rebooted the phone this morning. I'll post here again if the problem persists. Thanks!

[Q] could my galaxy die?

Hello everyone I just bought a new phone which is galaxy s3 , I read that my model may suffer the sudden death problem.
The device is new from the box and it is the 16GB model.
Its unrooted and running android 4.1.2
More information about it:
Baseband version: I9300BOLK3
Kernel version : 3.0.31 - 742798 [email protected] -111#1 SMP PREEMPT Sat Dec 22 17:04:04 KST 2012
Build number: JZO54K.I9300XXELLA
Sould I be afraid of audswn death or any proccesor bugs ?
check the SDS threads in General, they have all the info you need
samsung claimed the latest update has fixed sudden death issue,so far I do not see anyone who updated to latest firmware complain about sudden death.
wait, was there an official statement? got a link?
depends on how damage ur s3 had taken and if ur on the safe kernels and recoveries
If you are on XXELLA and haven't rooted and changed kernel then as far as anyone is aware you are protected.....although there has been no official confirmation, but analysis by the hard working devs suggests you're safe.
If you decide to root then make sure you install a recovery that has the fix(most of them now) if you change recovery - likewise with kernel, if you change that.
Thanks alot for helping so i understood that i am protected , i didnt root / change anyting all is stock and i am on XXELLA is that right ?

[Q] How to get my SII back to stock so Kies i can get OTA updates again?

Hi,
had my S2 for a while now and installed ICS through ODIN as here in NZ the updates seem to come a little slower than the rest of the world!
but id like to be on Jellybean and heard so much about unsafe Kernels etc (most of it goes over my head haha)
but i figure my best option, as i dont want a bricked phone, is to go back to stock and get my updates the old fashioned way.
what is the best way to do this? i know other phones can do this through KIES itself...(entering a serial etc), does this work with all phones?
any help would be greatly appreciated!
ICS 4.0.4 stock kernel has brick bug. If you are on stock 4.0.4 then avoid any kind of wiping. If you want to flash official JB go here
Hi friends I own Galaxy s 2 i9100....I got it from UK 3 mobile.. After coming to India I have flashed it with a ROM which is unlocked version as its is locked to 3 network...after the flashing I connected it to kies for backup and found the same message as others in this thread mentioned...so I tried reflashing it with a ROM that is compatible with Indian version and got the issue solved ...I am providing the details of the rom now I am using
PDA: I9100XWLQ2
phnoe: I9100DDLPC
CSC: I9100ODDLPD
BUILD info: Fri oct 26 16:04:15 KST 2012
But recently KIES software in my laptop got updated and when I connected my S2 it stated that my phone is not compatible to update from KIES. But, the same day when I connected wifi in my phone I got a message that an update is available and its done successfully.
Now can any body help me to get that issue sorted out when connected to KIES as it accepted before and now why it is not accepting ??
Thanks in Advance

thankyou! very helpful...now that i have read that entire post i just have one question....isnt that still classed as a wipe? the first thing it says to do is put your phone into recovery mode then wipe?
Flash Siyah or Dorimanx kernel first (without wiping ANYTHING). Then use the CWM that is installed with either of those to...
A) complete the wipe processes. And
B) flash your chosen stock ROM.
When you flash your ROM, you WILL overwrite the Siyah or Dorimanx kernel you previously flashed as your ROM has its own kernel (and CWM). As things stand at the moment, this is probably for the best because there have been some changes to CM10.1 that have made a lot of standalone custom kernels incompatible with the ROM..... for example, I lost my baseband when I flashed Siyah on top of CM10.1 and I'm told that there can be issues with video recording too. Which brings me to make one more point....before starting any of this...
MAKE A NANDROID BACKUP....
it's your safety net if it all goes wrong (personal experience is a brilliant teacher lol).......

I went from MIUI back 2 custom rom I9300XXEMC2_I9300PHNELL2_I9300CEELL1_HOME.tar
I flashed bootLoader_I9300XXEMC2.tar with odin.
i also flashed recovery-cwmtouch-6.0.3.1-GTI9300
This are the settings i currently use but it works for 10 min and then it starts 2 boot again

When i go to CWM and i want to install custom rom cm10.1 i get the error: BAD
Another problem i got, i cant connect my phone with my laptop. I got a driver problem: CDC Communication Interface (that 7 times in my device management) and Comneon Suspend. I think it all has to do with each other
Sorry for my english...

[Q] Can't remember which custom rom I have and want to update

I had some troubles with my S3 i9300 with constantly freezing, after investigating about it I decided to install a custom rom with a newer android version than what I had at the time.
Now I can't remember which rom I installed and I want to update to a newer version, after reading in some of the rom install instructions, it mentions some requirements that to tell you the truth, I don't understand about them, or I don't know if my phone has them. I do remember that I installed using the custom recovery menu.
So the question is, can I install a custom rom in my phone? Right now I'm interested in the latest version NeatROM, here is my phone info:
Model: GT-I9300
Android: 4.2.2
Baseband: I9300XXUFME7
Kernel: 3.0.31-702147

Just download the ROM you want to install.. Put it in your sd card.. Reboot to your recovery.. Make a backup of your rom and efs... And flash the latest 4.3 Sammy rom anyone you are interested in.. but remember to flash a modem for your region during installation.. In case of neat rom you will have that option in aroma installer itself... so ya go ahead and perform all these steps most important of which are backing up efs and your rom...

Standard method put new rom on ext sd card .
In recovery format system data cache and sd card .
Flash custom rom via recovery .
Thanks for the responses, I did it like that and everything is working ok.
Spoke too soon, data over the mobile network is very slow, I'm restoring the backup.
