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.

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.
http://forum.xda-developers.com/showthread.php?t=1221105
I have an Xperia Play and I decided to flash it with cyanogenmod. First version I got working was the 7.1.0.2. Everything was working fine except for my network: the phone didn't even ask me for the PIN.
After this, I tried the experimental CM9.0 RC1, yet I found the same problem: SIM card not recognized, phone didn't ask PIN, no networks found.
At this point I realized I didn't install a baseband on my phone and tried that. I started flashing it with flashtool, but then forgot to install the .zip file from CWM.
With this the phone was asking for a PIN, but soon afterwards it asked for a "SIM network unlock code". My phone is not sim locked.
After I installed the baseband -36 correctly (with the .zip file from CWM), it returned to behave like before: no PIN asked, no networks found.
Is there a fix for this? I searched for a whole afternoon for this, didn't find anything. I'll give further details if needed, thanks in advance.
By the way, if I revert the system to the stock sony ericsson ROM everything works fine. My carrier is "3 Italy".
EDIT: Installed CM9RC2 and now everything works fine except for wi-fi. Well, i suppose it is to be expected from experimemntal builds.
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!!!
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.
I've done a lot of searching around here and couldn't find anything that could get my WiFi working again. A while back I was following a tutorial that would let me edit my network bands, but I could never get it to work.. Shortly after I noticed my WiFi stopped working. I'm not sure if it's a coincidence or not. Anyways, I've tried everything. I've used stock RUU's to flash it back to stock (erasing everything), installed different ROMs, Kernels, etc. I've noticed the WiFi will work shortly after a fresh install but after a bit it just stops. Turning it on will give a WiFi error followed by "settings has stopped working". I've even opened up my phone and made sure the antennas were connected correctly but that didn't do anything. My Bluetooth works just fine though!
I'm s-off and rooted
Helped one of my friend - installed latest firmware update, but he has phone without root and locked bootloader + s
-on
Where can I find the firmware update?
Did you try using a different SSID ?
Or did you verify the RUU flashes clean ?
Maybe your WiFi Chip is broken
