i am new to custom roms and etc...
i have installed the cm10 beta successfully but i had no network/signal, i went to system settings-more...-mobile networks-netwirk operators and tried both search networks (mine is Vodafone contract) and select automatically but it comes up with "error while searching for networks"
i reverted to the cm9 stable version and installed it successfully hoping that this would resolve my problem but it hasn't, i done the same process stated above and the same thing happened.
are there any patches or updates etc that i could use to fix this problem.
i have searched the web and found many devices have had similar problems.
i would really like this fixed asap cause i like the cm9/10 but this problem has stopped me from using them, please help!!!

So I recently got back into the country and I had thought to update my CM nightly to the latest revision and I have run into some really weird wifi issues. Currently my wifi is unable to find any networks and I have even tried installing different wifi scanners from the market to see if any can detect any and they all fail to. Yes I have tried searching various threads but the only similar issue(find 0 networks) seemed to have magically solved by trying to add a new network and it just connected, which did not work for me.
Surprisingly turning my phone into a portable wifi hotspot still works which makes me think it is not a hardware issue but I may be wrong. I have tried going back to my previous backups of my roms and none of them seem to be detecting anything. I have also tried various radios and I am currently on the one listed below. If anyone knows the solution to my problem it would be great.
Rom : CM 7 Nightly build 92
Baseband: 12.28b.60.140eU_26.03.02.26M
Kernel: CM Stock 2.6.35.13
Any help is greatly appreciated thanks.
Flash superwipe through recovery and then flash a fresh rom. See if that fixes it.
Sent from my T-Mobile G2 using XDA Premium App
Wow the Superwipe worked when normal formats didn't. Thanks a lot!
I've found quite a few seperate threads on different sites about this same problem, most with different solutions.
My Original Aim:
To install the latest build of Cyanogenmod on my R800i
Methods:
I unlocked the bootloader, that worked fine but...
Problems:
after root, the phone cannot read my sim card (this is the general problem many of us seem to be having)
also:
Wi-fi connects fine, but...
the web browser cannot connect
the market seems to just crash second after opening [seem to have gotten through this problem now, will keep updating]
Any G app constantly requests login details but still cannot connect
This basically means i can't get the clockworkmod ROM manager from the market, so can't continue with my cyanogen flashing.
[from more searching it seems clockworkmod ROM manager can't flash on the play, so trying to boot it myself using other guide]
[now using fastboost to boot up SWD recovery, and then load cyanogenmod from there. will update with results]
[couldn't flash on cyanmod, some sort of assert failure... this is not going well at all]
Theory:
It could have something to do with the newest firmware update from sony? (might be UK only)
Either way, Everywhere I search seems to have a different solution, any chance anyone here has some clear and better advice? I'd like to get Cyanogenmod running, but if not then just returning back to the default firmware would be good enough.
I'll keep working at this and update as I find solutions. Eventually update this into a thread explaining how to fix the problem.
[EDIT: another useful thing might be to figure out what the source of the problem is, so we can tag/fix those instructions that might cause this]
Check the BaseBand version if it is "unknown", if it is, u need to flash your phone again
Same thing has happened to me , after unlocking boot loader and then rooting.
I no signal , (no service) message , also baseband is unkown , I have flashed a few uk roms and no good
Keeps saying insert sim card , i have tried o2 and tmobile , just the same.
EDIT : MANGED TO FIX MY PROBLEM, FLASHED THE FIRMWARE FROM THE THREAD BELOW.

EDIT: Fixed. I had already tried flashing updated stock roms before flashing CM9 and it didn't seem to help but I tried a few more, and the one called "R800_4.0.2.A.0.79.ftf" fixed it. After that I wiped everything, installed cm9 again and now it gets a signal
original post:
I installed CM9 on my Xperia Play and now it doesn't properly detect the SIM card. It says "No service" and when searching for available networks it gives an unhelpful message "error searching for network". If I try to add the APN manually it gets ignored.
I've seen other people with this problem but every solution I've found has been things I've already done, or broken links.
I updated my baseband using Flashtool but it didn't help and in fact the phone seems more sluggish now after doing that.
The SIM works fine in another phone. These are all unlocked devices.
Hi there, my first post.
I've used arco68's guide to root my S4 mini LTE (serranoltexx) and flashed the CyanogenMod 11 M9 snapshot (cm-11-20140804-SNAPSHOT-M9-serranoltexx.zip), but the WiFi isn't working properly. Sometimes it connects (very rarely), but most of the time it just says "Connecting", "Authenticating..." and then goes back to say "Saved, secued with WPA" and the process repeats again.
I've tried flashing the following ROMs, but the WiFi isn't working properly on either of them:
cm-11-20140804-SNAPSHOT-M9-serranoltexx.zip (current)
cm-11-20140708-SNAPSHOT-M8-serranoltexx.zip
cm-11-20140813-NIGHTLY-serranoltexx.zip
Other things I've tried so far:
Using CM File Manager to delete contents of /data/misc/wifi and rebooting, as described here, but it didn't help.
Installed SQLite Debugger, went to Settings Storage > setttings.db > Global, where I wanted to change the value of wifi_display_on to 0 as described here, but it was already set to 0, so no luck here.
Changed the Region Code in WiFi settings (as described here) to United States, then to Europe, but this didn't help either.
Installed the latest nightly update, but still nothing.
Basically, I've tried everything I could find, but the WiFi still doesn't work, and I have no idea why. I don't want to downgrade to CM 10.2, since later when I decide to upgrade to CM 11, I'd need to wipe all the data and make a clean CM11 install. Also, I don't want to flash any other ROM except CM, so telling me to install Paranoid Android or anything else wouldn't help.
If you have any ideas how to solve this, that would be great! Also, feel free to ask for any additional details.
Update: I've just discovered that it connects to open WiFi networks without any problems (though I've only tried it on 2 so far), so probably WPA encryption or my old home router can be the cause of the problem. I can only change my home router to WPA (it doesn't work with WPA2), so I've yet to try it on another router supporting WPA2. If that works, it would solve the whole problem! I'm ashamed to say I haven't thought of this earlier...
Update 2: I just tested it on a WPA2-protected WiFi network and it connects without problems. The most likely conclusion seems that CM11 has some problem with WPA, so for the time being I'll switch to another router with WPA2. Hopefully gets fixed with the next snapshot!
Hi,
After flashing one of the CM11 nighties I started getting the message "error while searching for networks" when as msg says searching for networks, I found out too I can't use any USSD code I get the message "Connection problem or invalid MMI code" however I am connected to my local network and able to use LTE.
Flashed the latest modem version and for some time it works but now again it doesn't work, attempted flashing again and issue persists.
Attempted a newer version and switching to Paranoid and issue also persists.
Help?
My device is a SGH-i747m from Telcel (Mexico).
Does this happen with a completely stock ROM?
Sorry for late reply, my phone got bricked
Anyway, I was able to use USSD codes again after going back to 4.1.1 stock, therefore the problem is either 4.3 or the modem upgrade which disabled USSD codes.
