After Update to 4.1.2 can't switch WIFI on :( - Galaxy S II Q&A, Help & Troubleshooting

Hey Guys
Since many apps don't support GB I was forced to do update.
After flashing with original JB 4.1.2 everything seems to be ok, but there is no way to turn wifi on.
WIFI icon on bar is half-highlighted, tapping on it gets no results......Wifi tethering not working also
Cache and Full Wipe was done, there was suggestion to flash with "siyah kernel" - also not working.
It seems that problem is related to fault ROM file because on ICS and GB wifi works fine......
Any tips? suggestions?
i9100 without wifi is useless :crying:

Did you flash the correct JB update? Maybe try a different STOCK JB rom from a different region.

Or directly try to install a custom ROM, for example CyanogenMod.

[Q] GPS don't get fix

Hello to all,
I've been looking on this forum, searched for everything I wanted, and always get an answer, but this time I need to ask some experts here. As the title says the gps don;t want to get fix even on clear sky and without any building around. I used many programs one of it is "gps status" where are shown 0/11 fix, basicaly there are 11 satelites available I believe. I have tried almost all the roms available in the development section but none of them worked, even the cm7. Used another firmware and there is fix to this. If I use the original samsung rom untouched the gps is working normaly. Please let me know what I doing wrong?
Thanks,

try fasterfix from the market.maybe it would help
Well for some reason my gps is working now, what I've done is flashing with odin a multiple file (my chose was a froyo firmware) the I flash with odin the latest ks9 one package file, working great even with cm7.2, got fix in 19 sec for me is great (also using the gps config from http://forum.xda-developers.com/showthread.php?t=1320626
Thanks
Guys before you change the base band and all try Faster fix from the market.. worked for me.. now the gps gets locked in few seconds.. really useful app.. and also I recommend maps v5.8.. most of the time other versions gave me force closes when using navigation.. Hope this helps..
my gps always shoes "your current location is temporarily unavailable"

[Q] Need help getting Wifi Working on Samsung Galaxy S2 I777

So i was trying to Root my Samsung and I think i miss-understood the operations and processes.
Samsung Galaxy S2
Kernel 2.3.6
Downloaded SGH-I777-ATTGalaxyS2RootStockZedomaxKernel.tar
Installed, no problems, all good, but no wifi... freaking out.
Searched the Forum... found there was an issue.
Attempted to reload the stock kernel StockKernel-PDA.tar
Installed, no problems, back to 2.6.35.7 Gingerbread.UCKK6
But Wifi will not enable....
Kinda freaking out as Dont understand how the Zedomax and Stockkernel are 6/8mb... but the rest of the post are talking about a 200/300mb file which needs to be downloaded...
Just looking for help on how to get back WiFi?...
read thru: http://forum.xda-developers.com/showthread.php?t=1286432
...If you bootloop or things behave wacky, enter 3e recovery (stock kernel means stock recovery) and do a Wipe Data/Factory Reset. If you are reverting from UCKK6 back to UCKH7 you MUST perform this step or wifi will not work.
I Did not go from UCKK6 to UCKH7... i don't think?? So any help on what i need to do would be awesome!
AT&T is the carrier.
Also without having to 100% wipe and re-install.
You need to find the "Return to stock" thread and go from there.
Zedo's kernel is ancient, it will not provide wifi with UCKK6 system images.
Only my kernel, the UCKK6 stock kernel, and (maybe, not sure) SiyahKernel will provide wifi with UCKK6.
Kernels are <8 MB. 300MB = full kernel and system image restore.
My guess is you flashed a UCKH7 stock kernel.
Found a return to stock thread and it mentions a RUU_Ace_Cingular_US_1.80.502.3_Radio_12.39.60.19_2 6.06.04.06_M_release_166557_signed.exe as well as a pd98img.zip which are also both 290MB...
Found another thread for Official i9100 Firmwares KG, KH, KI, KJ, KK1/2/5, KL1/2/3, LA2 Download but none are for USA/AT&T.
There are a LOT of thread on this and i have been reading thru as many as i can...
If the Stock Kernel or Entropy512 Stock kernel File name or description can be posted i can do the update thru odin...
On the Zedomax, i saw that after i flashed... never blindly trust youtube =(

Of the items you mentioned, NONE are for this device.
I suggest searching a bit more methodically - look in this forum subsection, and look at the sticky threads in the General and Development forums. Threads are made sticky for a reason.
Hello ALL!!! Thank you for your help...

Seriously, if someone can't distinguish which phone they actually own or what forum they should be in, why are they even trying to flash it? What is wrong with some people?

SHOstock2 v1.3 works well with WiFi if you want a custom ROM (ICS).
I was using UnNamed v2.2.1 and it was very stable, but I wanted to try Ics, so I'm now using the AOKP 4.0.4 but I'm having issues with the Gps, still doing some tests, if I dont find any, then I'll move to SHOstock2 v1.3

Sounds like it could be hardware failure. To test that, flash back to straight stock followed by a wipe data/factory reset from 3e recovery. If the problem persists, then it is either a problem with your phone hardware, or a problem with the available wifi router signal. You can test the latter by trying to connect on different routers.

Thanks for your response.
I dont want to belive that my hardware is broken.
But i flashed again my SGH-I777, and the problem persists.
My wifi just says "Turning on" when I push button, and it never boosts again.
I changed the kernel and the rom. I restored to old factory settings, and nothing works.
I would like to get back my wifi.
i appreciate your opinions about this issue.
WIFI suddenly stopped
My WIFI also suddenly stopped working
on 7-1-13 I installed aokp_i777_ota-eng-task650_6.24.2013 worked for a month
Yesterday the WIFI stopped connecting. Got a constant "Turning on Wi-Fi" message but nothing else
I installed aokp_JB_i777-ota-eng.task650-ktoonsez-11.20.2012 which I had been running for the last 6 months
Same problem
I did a full wipe. Wiped cache, data, dalvik. Did a fresh install, then wiped cache, dalvik and fix permissions.
Same
a i9100 thread linked a video of a leaking battery inside that disabled wifi
took phone apart, no obvious signs of hardware failure (have pics)
used odin3 v1.85 with ATTGalaxyS2Unroot_SGH-i777.tar to unroot
wifi will turn on scan for a minute then turn off -- will not find any AP
router working fine with my other i777
anything i missed?

hey brother, first of all, your wifi is not damage fisically. But you are in the same situation that i was.
my SGH-I777 is working very well after too much work with it.
i gave my cellphone to my little brother, and two days later he told that the wifi was working fine.
i made this face O_O i couldnt believe what he was saying.
right now i dont know, how he resolved the problem, the only things that he did was change the OS i guess.
i will call him tomorrow to ask about the solutions, but man, dont worry too much coz you just like my brother, will resolve the problem
It is not hardware...
found another thread that suggests FXR WiFi fixer app from play store.
Ran it on the the AOKP JB 4.1.2 from 11.20.20102
seemed to solve issue -- connected to wifi but lost connection after ~30 min
same issue -- constant "Turning WiFi on" message.
ran FXR again -- connects temporarily then loses connectivity
same thing every time i run FXR
should i use a different ROM?
which one?
any help is GREATLY appreciated
Thanks
mike

You could ask in the AOKP thread if there are others experiencing wifi issues with that rom. If not, a fresh install of the rom may solve the issue. It definitely sounds like a firmware issue, but when there is any question whether the issue is firmware or hardware, the test is to flash back to stock and see how it works. As far as which firmware to use, there are a number of different firmware that are completely stable. You should read through the developer threads, and then try them out to see how you like them.

[Q] Samsung Vibrant: flashed ics, but problems

I flashed the ICS Euphoria ROM for Samsung Vibrant, but now I cannot connect to wifi and my phone doesn't pick up my network (neither does it search for it). I have not flashed the kernel yet because I do not know what I need to wipe in CWM Recovery before installing it.
So how do I flash the kernel, and how do I get my wifi and mobile network working again?
Any help would be greatly appreciated.
Thanks.
EDIT: i flashed the kernel after wiping dalvik cache, but its still not picking up my network or wifi
EDIT2: WIFI works now (I was dumb) but still no carrier signal. It just says No Service. Please help.
EDIT3: turned out it was the ICS Euphoria ROM that was at fault; i have Passion now and it works fine.
RESOLVED BY MYSELF. THANKS FOR THE HELP

[Q] S3 issues after Reverting to stock rom, coming from jelly bean rom

A few weeks ago I flashed a Jelly bean rom which worked just fine, even though it was a bit less smooth than the stock rom. The only problems I was facing were constant wifi disconnects and huge battery drain.
So I decided to go back to stock rom after backing everything up using titanium backup. After doing a factory reset I realized I had stored my backups on the internal SD card, so that was wiped. Guessing there is no way to get that data back, but the data loss aside I am still facing other problems after getting back to the stock rom.
I9300XXLG8 is what I am on atm. The day after I flashed it my touchscreen stopped working everytime I unlocked my screen, so what I did was turn wifi notifications off and disabled Wifi power save mode. It fixed the issue but there is more. My 3g suddenly stops working now and then, it would just be stuck at a certain % when downloading apps from the play store while still saying it's receiving a signal. And then last but not least, I really have this feeling that my battery is still getting drained alot faster than before going to the jelly bean leak and then back to stock.
Also, how do I know what Kernel and modem to use with which ROM?
Help would be much appreciated

Flashed Omega rom and now WIFI range is extremely poor

Hi all,
Pebble Blue i9300 SGS3 unlocked
Was on Android Revolution HD 14, full wipe flashed Omega 33.2 which is when I notice the issue where I would only be able to connect to WIFI within 3m distance from router (used to work from outside house and across the road now only in the same room). I can see my network at full strength in other rooms of the house but I receive authentication error/incorrect password despite it being correct.
I then decided to rever to stock rom, I unrooted and did triangle away and flashed the rom my phone came with, problem still persisted.
Then flashed back to Omega 33.2 with full wipe and problem persisted.
Did a series of full wipe -> flash -> factory reset in OS -> full wipe -> flash -> factory reset, after which the problem still persisted.
Flashed Omega 33.3 today over top of Omega 33.2 with full wipe and format /system from CWM, problem still persists now.
Any ideas on how I can remedy this?
Thanks
Van
this might not be related but give it a try
-Try changing your WiFi channel maybe to 6? or 7
Try a different kernel try a different rom .
jje
Hi, thanks for the suggestions.
I have tried already different WiFi channels and have tried 4 or so different ROMs and the siyah kernel. Have tried aosp and stock firmwares along with the Sammy based jellybean ROMs. Have tried cm9.1, stock 4.04, stock 4.1.1, leaked 4.1.2 stock, omega v33.2 and 33.3.
WiFi was perfect before my first flash of omega v33.2, immediately after the flash it was extremely poor and hasn't changed through all the ROMs I've tried since then.
Wondering if it could be somewhat coincidental and my WiFi module if faulty. I could reflash to stock and send for warranty but would only like to as my last option.
Thanks

Not sure if it's the case with Omega ROM, but I had a similar issue with an AOSP-based ROM. Solution was simple: flash back to stock ICS ROM, connect to wifi, then flash back to JB ROM. NO problem after that. might be worth a try before sendning it back for warranty.

Thanks for suggestion, had tried that when the problem first appeared and it hadn't worked. Just went back and did it again, wasn't able to connect to WIFI on stock rom I9300XXALE8_I9300NZCALE5_NZC, did factory reset from within rom, still unable to connect. Rebooted to stock recovery and wiped data/factory reset, wipe cache and rebooted straight to downlaod mode, flashed stock ics 4.0.4 I9300XXALE8_I9300NZCALE5_NZC again which is what came on my phone. Still no go with WIFI despite having 4 of 5 bars of signal. I get the connecting symbol which goes for a while then changes to scanning and back to connecting again, meanwhile under the wifi network in question it just remains "saved, secured".
Just performing triangle away/re-flash stock once more to preapre to be returned for warranty.
Any other suggestions?
Thanks
Van
