Since a picture, and in this case a video, paints a thousand words -> http://www.youtube.com/watch?v=qCkKkkukujI
Here I present to you my dilemma.
Before you ask, the phone is rooted, running cm7.1 nightly.
At the time of recording my modem is KI3.
I have tried about 4 modems, in the K family and no luck yet.
I cant put my finger on exactly the time this happened, but somewhere in the past 3-4 days and nothing significant happened to spawn it. (ie I wasn't changing roms or anything of that sort.)
Every modem I put on does the exact same as the video.
However generally the first boot after a flash, the wifi tends to connect, next boot = no go.
I have also used 'gs2blitzer v1.6' which is a script to clean out old kernel files and temporary bits n pieces between flashes.
So any helpful suggestions you have will be appreciated.
Do a backup with ClockWorkMod and then flash another kernel. (siyah, for example).

I just flashed siyah as you suggested, no luck.
Still does exactly that in the video I posted earlier.

Tried a full-wipe?
Sent from my GT-I9100 using XDA
are you using the i9100 or a t-mobile branded or other variant?
did you have the problem before you flashed the new rom?
im using wanamlite ics 9.1 rom using the XXLPH kernel and my wifi works fine. XXLPH is still beta i think btw
Yes it has been wiped numerous times.
Wiping individual partitions from cwm, wiping dalvik, using the cleaning script to clear old kernel stuff..
And yes it worked prior - if you read my first post, nothing happened for it to stop working. There was no flash involved to stop it working.
Oh and its an international I9100.
Some extra info on the subject.
Disconnecting and deleting the AP, restart phone, it will then connect.
If i disable wifi then re-enable it, it wont connect.
Stuck in the loop of Scanning, connecting, disconnecting, over and over...

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 was running UnNamed v2.2.1 and flashed the Siyah Kernel. However, after flashing the new kernel, in Settings > About the kernel version doesn't display that its Siyah but the CWM does change. Does this mean the kernel is not installed?
I assumed it was installed so I flashed the Init.Doh script. After it installed, my status bar was missing.
Since everything was messed up, I ran the Init.Doh uninstaller and tried out a new rom.
Did a factory reset, wiped cache and Dalvik cache, then installed SHOstock. Within 5 minutes, I lost signal.
Flashed back to UnNamed, but the signal loss was consistently happening. So I formatted system, did a factory reset, wiped both caches and installed SHOstock again.
As of now, I constantly lose signal. Tried flashing compatible modems but nothing is working. Does anyone have any idea of what to do?
I use CPUspy to see whether or not a specific kernel flashed successfully. As far as he signal loss..no idea sorry. I would start from scratch and flash bts and go from there maybe..
Sent from my SGH-I777 using xda premium
I would say the signal loss has nothing to do with the phone but your area if it happens on multiple roms
And the cwm is supposed to be different on siyah, it flashed fine and the kernel version in about phone should not change, changing your rom was silly

Thanks for your replies. I think my post is confusing so I'll try to clarify.
Signal was prefect on UnNamed. After flashing Siyah and the Init.Doh script, the status bar went missing.
So I did a factory reset and wiped everything before installing SHOstock. When it booted up, my phone kept losing signal. So I wiped again and went back to UnNamed but the problem persisted.
I'm wondering if the problem is caused because I was never sure if Siyah flashed properly. In Settings > About Phone, the kernel version never said it was Siyah. BUT my CWM changed to the Siyah version. However, even if this was the case, I don't know why the signal problem continued after wiping everything and formatting /system.

CPUSpy displays large amounts of information not displayed by Settings->About Phone.
Although I would've expected Siyah to cause a version bump to 2.6.35.14... odd
Time without signal is a known gingerbread bug, if that's what you're referring to signal loss. It doesn't affect your battery life, just the android battery stats is all around messed up.
The big solar flare has a lot of people blaming 33204803428 different things on signal loss... basically everything BUT the fact that we're experiencing one of the largest CMEs to hit Earth for a few years.
After multiple factory resets, cache wipes, system formatting, and flashing ROMs, everything seems to be running properly again. Thanks for the suggestions!
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.
HTH
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?

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"
Hey guys,
My SGS2 is currently facing what I call a Wifi bricked. After flashing several ROMS, I have discovered that my Wifi just cant turn on anymore. The Wifi toggle button just seems to be grey out. When tried to turn on, it says "Turning on Wifi" and it goes blank. Wifi did not manage to turn on
I have also tried flashing several roms and kernel in hope of fixing it. I have also flashed to stock sgs2 roms from sammobile but still failed. My last ROM using was the NeatRom. Its a good ROM but just dont know what is causing my phone to face such problem. I have tried flashing the previous roms and kernels that have WiFi worked but still failed to resolve the WiFi issue
I am currently running on Super Nexus 2.0 build 1.
Please help.
Very much appreciated. Sorry if i did not provide enough information.
What Rom
The best is flash the rom again

I assume you are wiping all data while changing ROMs, right?
Is the phone on warranty? Since it's not ROM or kernel or modem specific, it must be a hardware fault.
Try the kernel cleaning script right before flashing a ROM, just in case.
Yea. I do a data wipe whenever i flash a new rom. And also I no longer has warranty for my phone. I'm guessing it may be hardware faulty too but just not too sure about that.
Hmm.........

Try flashing a different radio (modem). It could be that at some point a new modem was flashed (like when using leak) and it has corrupted in some way.
There is a modems thread on here somewhere, use search.
First of all: I have had my S II water damaged some months ago. It works fine that far (exept that the sensor keys are dead). Not sure if there is some other hardware malfunctioning...
Currently im running on MIUI and everything is fine, but recently I found out that no other ROM will work on my Phone:
- Samsung stock ROM runs extreme (!) laggy. Took me about 5 Minutes to go through the menus and enable USB debugging.
- CM9/ AOKP will reset immediately after system startup
- CM10 shows laggy boot animation for few secs, then bootloops
Only other ROM that works is "cMIUI". Which is a CM10 based ROM only with a MIUI userinterface...
What can I do to find out whats the problem with my phone??
Thats weird. Have you tried wiping data before flashing each of these ROMs? Next time, try formatting /system, /data, cache and dalvik cache. Also, have you tried using those kernel cleaning scripts, etc?

Wiped and formatted like hell. I've hit every single wipe/ clean/ format option in the recovery. Also I have installed a dualboot kernel and installed CM as "second rom", where no ROM has gone before.....

Only one option I can think of is to go back to stock samsung rom then claim your warranty if you have it. Or, make a logcat and paste it here (upload to Dropbox or somewhere then past a link over here) and someone experienced might take a look.
Since you've already wiped everything, I'm more inclined to think that it's a hardware problem now. However, let's hope someone more experienced pops in and helps. Good luck

In both logs the phone booted and showed the Pin dialog, then after few seconds rebooted.
As the Phone had been waterdamaged Im pretty shure warranty is absolutely void Also I think that the problems are due to some Hardware malfunctioning. Just want to know what and if theres some way to workaround.
