Hello everyone
Since a few days ago my S2's Wifi is not working
h.ttp://i.imgur.com/ojDOm.png
The icon stays like this, pressing it does nothing. it happened 3 - 4 times before, usually, I'd just reboot it and that would do the trick (I google'd a bit and saw this is a common glitch when trying to turn wifi on), but not anymore, it refuses to turn on no matter what I do, rebooting, shutting down and restarting, it's stuck.
h.ttp://i.imgur.com/KeMxb.png
I can't Scan, add a network nor switch the toggle on/off because pressing them does nothing, So... I thought I should do backup and factory reset it, nope. still stuck.
What's wrong with it? Any ideas? The phone is a year old, running 4.0.3 Stock
Sorry about the dots in the URL's, can't post links yet.
Edit: Forgot to mention it started doing this since I got ICS, maybe I should try flashing it to see if that fixes it, I'm kinda reluctant though, since the factory reset didn't seem to do anything and I haven't done it before.

Do the steps below
- Boot to CWM recovery
- wipe cache partition
- wipe dalvik cache (under advanced)
- fix permissions (under advanced)
- reboot system now
The above steps will not make you lose some files and data
If that does not help, then flash another kernel
Since putting a custom kernel on my phone my bluetooth does exactly the same as what your wife is doing. Only way to turn it on is to reboot the phone whilst it is trying to turn on (ie whilst it is a shade of green)

you should be Ok its relativley straight forward
Well, Flashed in CWM Recovery and CM9, wiped cache, Dalvik cache and fixed permissions but the wifi is still not working... it's still stuck at "Turning Wi-Fi on"
I really have no idea about kernels and that stuff, I don't know how to flash 'em (unless it's the same as flashing CWM) or which one to get at all, since theres too many and I don't know what they do/know if they're compatible.
Flashing kernels are the same as flashing ROMs and modems..
There are 2 ways to flash kernels.. 1 is via odin (.tar file) and 2 is via CWM (.zip file)
Now, if your ROM is on JB then use a JB Kernel
If ICS = ICS Kernel
AOKP = AOKP Kernel
AOSP = AOSP Kernel
The thing with kernel is that you have to match it with the ROM's base..

Hm...Checked my phone 7 hours after flashing CM9 on it and suddenly the Wifi's back on
Any explanation for this? It doesn't make any sense, I didn't even touch the phone during that time and it fixed itself?
Edit: Thanks for clarifying that up saywhatt, since I already flashed if and thus, voided the warranty I might as well go ahead and try flashing a kernel to improve battery life and get into the scene.

No problem.
Perhaps the ROM was "settling"? Lol i dunno.. but i'm glad to hear you got it sorted out. You can revert back to complete stock if you have some serious problems and it is needed to be sent to the service center..
1 download triangle away to clear the binary count
2 flash stock firmware
Voila! U no longer have a void warranty

Hey guys. I've been an Android & XDA user for a while now, so this question shouldn't be about a nooby-sitiuation.
My friend bought an AT&T Samsung Galaxy SII (SGH-i777) this week. I've been trying to flash CM7 ever since. I got the rooting done, the properly recovery (with no signature / "abort" problems)
The rom seems to keep bricking the phone. Its simply unflashable. I seen tons of people on XDA who got it to work, with barely any serious problems. I troubleshooted the problem myself, and its simply just the CM7 roms. I would do a full wipe, and then install the rom like I would on my other Android phones, and the installation is successful. When it boots, it gets stuck on the Galaxy SII boot screen (not the splash/boot animation screen) and it would stay on it with a yellow warning triangle on the bottom.
I tried flashing other roms, like Cognition X2, and they worked. Its just CM7 on this phone... which is odd because CM7 is usually stable (nightlies aside.) Especially since the 7.1 stable version was recently released. Anyone can help me get the rom up and going? Would be highly appreciated.
did you try to wipe dalvick cashe as well when you wiped data?
I just flashed it tonight myself and all I did was reboot into CWM and did a Wipe data/factory reset and then Wipe cache partition. After doing that, I simply flashed the cm7 zip file that was loaded on my internal sd. Rebooted and no problems.
I didn't have ANH ISSUES installing it but I know I read that some.people bad to flash it twice initially. So flash it, then when it goes back to the recovery screen flash it a second time. I also remember users on the international SGS2 bad to do the same thing. Most have no issues but I think they found that it depends on what you used to root your phone (on the SGS2 internationals) and I THINK some had to do the same here. Try it and if it works just hit the thanks button.

if you flash it and get stuck in a bootloop, just pull the battery, and 3-finger back into recovery to flash the rom again.
keep doing this until you get it up and running - took me a few times, including a couple of battery pulls.
How do you boot into recovery? I know On the SGH-i777 you have to hold the Vol down+back+power to get to the Download mode, but I tried everything to get to the recovery itself.

Yes. I've flashed many roms before, this seems to be the only one I had ever seen a problem with.

Word.
Edit: To boot into recovery vol up+vol down+power
Had the same problem. Read somewhere to install the ROM twice in a row in CWM without rebooting inbetween. Worked like a charm.
Thanks for the feedback guys. I'll try this in the morning once I get my hands on the phone again.
Saw this type of behaviour on occasion with cm7 on my aria. Sometimes caused by a bad download of the rom. Did you verify md5s ?

Don't forget to do a master data clear /reset before trying to boot the new CM7 rom for the first time - clear out the old stuff. Works perfectly here.

I'm having the same issue. I'm getting signature errors when trying to flashCM7.1 stable. I've downloaded it two times now with the same problem. My question is, I'm trying to flash from on the phone itself, storing the zip in the download dir on the phone as I don't have an sd card. Will this even work? I've tried looking around and all I can find is flashing from an sd card. I can get one, I just haven't yet.

That's the way I did it. Put the update in the same folder on the internal SD card. I can't even access my external SD card from CWM.

Hmm, I'm not sure what I'm doing wrong then. I did a factory reset, and wiped the cache and get the same thing. I know it wiped because now I have nothing setup on the phone when I boot normally. Suggestions?
Quit downloading the CM7 builds for the International Galaxy S II. They will NOT work. That is why it fails. Look for the Galaxys2ATT build.
Sent from my SGH-I777 using xda premium
I got the build by going to the cm7 website, looking by device, finding the galaxy s 2 and grabbing the stable one. So perhaps that is the incorrect one and I'll look closer for one that has att in it, whenever the site isn't going up and down. They seem to be having issues today.
Make sure you're installing the version located in this thread...

Double flash made it work. Thanks guys. + thanks for telling me how to boot into recovery lol. Great rom.
Sorry for the newb issues, it was the wrong version. I got the att version from the thread previously mentioned and that worked perfectly. Thanks!
I flashed clockworkmod recovery from the CWM app. I rebooted and gave me bootloop. I force rebooted into recovery, cleared cache and dalvik cache and booted fine. The problem is that wifi says turning on, but never actually turns on. After the boot every app gave a force close so I installed them again with titanium.(I don't know if it is relevant, but I say it anyway!). I am on stock, rooted 3.2. Any help will be appreciated guys.
EDIT: I tried rebooting, and activating/deactivating flight mode (I forgot to mention that I have the 16gb 7500).

Don't know if it will help but it has helped me in the past to goto settings and have it forget all the wifi connections and then when it refinds the wifi you want to use connect to it again setting it up add needed, mine was just the default settings. Rebooted and everything was good to got.

Edit: After reading your post again, I'm wondering if its even found any wireless networks.

Thanks for your time but it seems like you can't help me.. Wifi doesn't work at all!!!! That is the problem. I managed to turn it off by rebooting after turning airplane mode on and off, but after reboot when I either click on wifi or turning airplane mode off, the problem is there....

could be wrong but if it just keeps saying 'turning on' then eventually unchecks itself, this is usually a kernel module error. try reflashing your kernel and/or rom?

Well, I was afraid of that. I had a similar problem with my phone a couple of months back. I just hoped that it wouldn't come to this...So it appears it's time for the tab's first custom rom...

Usually kernel issues can be fixed by flashing another kernel via CWM on top of it.

Well yes. I wanted to see if anytjing could be done by remaining stock. But I think it is about time to check out the ICS build. And try another rom. I think I will go for overcome. But thanks anyway!
sent from my nokia 3210
Might wanna try different options, Overcome has it's own stock kernel, aswell as ICS (Pershoots) but you are welcome to try what suits you best Hopefully the problem fixes itself, magically
Actually I flashed pershoot's kernel but nothing happened. A factory reset solved the problem, but I went on and installed ICS. It's just perfect! Anyway, it has its bugs, so I flashed overcome and everything is well Now I wait for cyanogenmod to work its magic...Thanks for everyone's help. Other thing that bugs me: If i flash stock rom from sammobile will the flash counter increase, since it will be an "official" rom?
Id like to know that too, my phone has been flashed aleast 150+ times over the past 7 months *Developer pride? * so I wanna know how to reset counters o.o
Well I have asked this question in 4 different forums and it is the third time on xda...Seems noone knows...
sent from my nokia 3210
I think official still count's as a counter+1, but so far only Samsung knows how to reset the counter :| I think they keep it secret just so their consumer's don't sue them saying "Samsung faulty products"
Hi Guys
I flashed the leaked ICS but hate it. Can I flash to stock GB via Odin? What about the baseband versions etc.., would it matter?
Sorry, I read another thread but it's unclear and I want to avoid bricking. Thanks
As far as what I've read you can flash stock from Odin or even use CWM to a previous nandroid of gingerbread.
Sent from my SAMSUNG-SGH-I717 using XDA
If you got your Note from AT&T, simply flash this stock ODIN:
http://forum.xda-developers.com/showthread.php?t=1506330
I went from ICS back to Gb cause I missed the tethering and it was easy. Just make sure you clear the caches and all should be well.
Thanks.. I was worried of the different baseband would have any adverse effect, but it doesn't sound like it will. I'll give it a try.
I Odin'd back to stock and I'm in a world of ****. My phone cant do anything, it just gets stuck on every swipe and reboots about every 5 minutes. Does anyone have any ideas?
Mines fine..only baseband is different, phone works.
Before I Odin to stock, I booted into recovery, factory reset and wiped cache. Odin, then booted into recovery and performed another factory reset and wiped cache again.

I had to revert from ICS to GB yesterday and, even tho I am on Telus, I had success by flashing the pda-odin-att-stock.rar image
I can't post links .. I'm too new. But literally.. google what's bolded above and you will find the hotfile link.
It replaced everything (including the recovery) ... FULL system image. Solved everything and brought me back to 100% stock.
So yes, I lost my root and my CWM recovery software.. but it got my phone working again.. I can reflash CWM and re-root as I need.
After the install, wipe cache, factory reset etc.
I too flashed the stock ATT rom but like the previous poster, it gave me a phone which started up but wouldn't work. When I tried to get into recovery mode, it went to a screen with the recovery mode stuff at the top, but with a yellow warning sign in the middle and some words about manual mode, and it would not let me do a wipe or reset.
Here is what I just did that did work.
I flashed the recovery-i717-cwm-b4.tar file with odin. This worked and allowed me to get into the "proper" recovery mode to do a wipe and factory reset, as well as a cache wipe. I then reflashed tieh the stock ATT rom, and my phone now is back to stock.
Current issue
Odin recognizes phone. I can get to download mode. it turns off. Ive let it set for 24 plus hours prior to this and there is no change. It will stay on for 10 to 15 seconds then turn off.
I have repartitioned, put in a new pit and kernel. it will not stay on long enough to install a new ROM.
leading up to this i had a sleep of death issue. that progressively got worse. It would turn on and be fine tell it went to sleep i could use all the apps if i stopped and it went to sleep i would have to reboot. I had during this point cleared all the cache devlik etc. to no avail. i then decided to flash to stock. I got about 10 seconds into the ROM flash and it turned off. now I'm at the point described above.
This has been w/ and w/o sim and external flash memmory
Thank you for any suggestions and help.
How old is your battery, and what kernels have you experienced this with?
What is a quick recap of what you were running/tried while this SOD problem started occurring, seems related to the DL mode shutting off.
Battery is the orginal, but i have 2 batterys 2 vibes. i switch batteries every month or so due to im more battery heavy then my wife, i have used them both fully charged.
Icy Glitch or subzero, though i think it was Icy. i was running slim ics. this is the only kernel i have ever had a sod problem.
Only extra apps i have installed or had issue with, 1 kindle stopped working on me well b4 any of this happend around 3 weeks or so. i installed adilko. Also installed calorie counter and myfitness pal these are the only 2 that really can be related. I had started using myfp more then the other for cutting.
only run music for during work, eh and for books, no games. i use advanced task killer to kill extra apps, a couple times a day to save on battery,
otherwise phone calls and txting.
Can you boot to recovery mode? If you can, try a factory data reset. You could use adb to push a kernel zip to your internal sd and flash through cwm but only if you can actually boot into recovery mode. If that doesn't work you could try flashing a different kernel through odin. Kernels usually flash in less than 10 seconds in my experience.

Have you tried flashing a custom kernel like Semaphore with CWM included and then try booting into CWM?

I was meaning to flash a stock kernel only, then flash back to stock JFD. I'm pretty sure you don't load a pit file when flashing just a kernel but I could be wrong, it has been awhile since I flashed a kernel through odin.

Hey all
For some reason today my phone has just started randomly locking up. Was running a nightly build of Cyanogen mod from Mid January. Never had any issues with it today.
Ive basically done a complete wipe of the system (/system, data, cache, dalvik, SD card, etc) and installed a newer nightly of Cyanogen mod, but it is still happening. Thinking it may be a hardware problem...
Any ideas as to how i can check whats going wrong?
Symptoms:
- Screen completely freezes on what it was doing. Screen state stays the same too (doesnt dim after a while)
- Haptic touch buttons sometimes work and sometimes dont (if they do work, all they do is vibrate, nothing changes on the screen)
- Tried a few button combinations to try and get it to respond again. Only way to get it goign again is to reboot the system completely (holding Power + Home)
Thanks

last option :- backup internal storage. do a megawipe. install any samsung based rom again.
if that also does not work. bring phone back to full stock i.e there should be no proof that u used custom roms and then try to get samsung to exchange it. sorry.
