[Q] Why is my sim not recognized in cyanogenmod?

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.

No Service Selected network (AT&T) unavailable! No Signal

I flashed in JB AOKP was working fine all of last night. I also entered my SIM Pin or unlock code. The first time I put in an 8 digit unlock code I have. Second time it prompted me I skipped it. I'm pretty sure it was the security pin and not the network unlock. I don't have any other phone's micro SIM I can insert into my phone and a local phone store's T Mobile SIM produced no different of a result except for replacing AT&T with T-Mobile (I have not however put my microSIM into another phone...because I don't have another micro sim phone). Reboot phone this morning and it's no longer working. Tried to enable 2g. Nothing. Tried a battery pull with the phone on, pulling the SIM (same message with SIM pulled out),
Wifi works
This sucks big time ;(
Note: I am pretty sure I did not network lock the phone or anything because the SIM prompt that came up when I flashed JB did not ask me for my unlock or network code (I would have known). The first time I entered that code was 'just in case it's asking me to unlock" but why would it ask me a second time then? So I doubt it was prompting me for a network unlock code. The prompt from youtube videos was different too.
Also APN is empty, but I think that's becasue I'm not connected to any network
Pressing Available networks brings up AT&T AT&T AT&T T-Mobile T-Mobile "311660" pressing any of them you get a quick window connect "too fast" goes back to/stays in available networks screen and says "Can't connect to this network right now. Try again later."
So I added the AOKP and Corresponding kernel yesterday and I mean it was working fine with 4g... apparently this thread says that you need to flash a new radio in some cases when you change kernels?

...what are you talking about. My IMEI isn't mentioned once in that post. In fact now that you mention it, since people's IMEI changed...nothing like that my phone still has its IMEI
I also did not get a "phone frozen" from entering the wrong code too many times...so I doubt its locked like that. There was a random reboot that I WOKE UP to, but nothing weird...it rebooted randomly but worked finely after that

I was proposing the theory that you may have lost your IMEI, since the symptoms you report were very similar to what I was experiencing when I lost mine, however since you still have yours, must be something else, eh?

Well, mine was definitely due to a lost imei that happened sometime when flashing.
I did get the network unlock warning thingy twice, and then had no cellular connectivity, which is why I mentioned the lost imei. I restored my nandroid back to stock, then used the method here with a little driver tapdancing to reinject my imei, and that solved my issues, but sounds like you have something else going on.

If I flash back to stock and no longer have the stock kernel, what is the steps for flashing back then?
1. flash stock kernel
2 fix partitions
3. factory rest/cache/davlik
reboot into oden and flash new image?

Long story short, Don't cut your own microsd..the sim pins on this phone are VERY sensitive and hard to fix/see. Don't bend em.

I am having the same problems right now, I keep on getting " NO SERVICE" - SELECTED NETWORK UNAVAILABLE" Error.
Rebooting doesnt help, flashing modem through CWM doesnt help. I know for a fact that the simcard it good because other apps that I install can read the sim with no problem, and my WIFI is working like a charm.
Someone got a solution for this? This is already like 4 days ongoing, please any help will be appreciated !!

Im having the same no service selected network issue. I can search and find att and the mobile but when I try to have it connect to att that's the error I get. I have an att SIM card in the phone. Sph l720 SIM unlocked, it didn't ask me for an unlock code or anything like that but I also don't get the invalid SIM card error. I've added the main apn from the att website but that doesn't help and the phone is current set to gsm/umts. If anyone has a fix please let me know, thank you.

[Q] Error while searching for networks while running Custom ROM

Hi people, currently I am running http://forum.xda-developers.com/showthread.php?t=1355660 ICS ROM but I cannot connect to my mobile network. In the last few days I unlocked my phone while running this ROM and I entered in the code I was given. The unlock was successful however I could not get onto my mobile network 3. When I went into settings > Mobile network settings > Network Operators I received the message "Error while searching for networks". I tested it with another SIM card and I got the same result. Then I tried reflashing the ROM and using a different ROM, the 4.1 Jelly Bean by Nikez. The result was the same. Another thing I noticed was that each time I restarted the phone it would ask for the unlock code again and each time I entered it the phone would say "successful", but obviously something has gone completely wrong. Also note I have Data Enabled and my Wifi/Bluetooth is completely fine. Can anyone help me on what has gone wrong? Thanks

Ok, what do I do with the file once I put it onto my SD card? Also will this fix the 3G problem?

You don't put it on your sd card. Extract it to your desktop, connect your phone and run it.

Does it work on Gingerbread ROM's ?

[Q] No 'enter pin code' screen and no signal

All of a sudden, when my HTC One X boots up, I don't have to enter my pin code anymore to unlock it, and I have no signal and no mobile internet.
What could be the problem? I have ejected my sim card to check it, but everything looks fine.

It looks like you flash a Custom Kernel and forget to Repack it or Repack it wrong

I've installed my rom + kernel correctly (IceColdJelly 3.2). I have switched a sim card with someone else, which didn't work...I then placed back my sim card and it asked for a puk-code and I had to set a new pin-code and it is working again now. Really weird though...it didn't even give me an error that it couldn't read the simcard or something.

Mobile Network Not Available

Hey guys,
This may be a silly question, but I can't seem to find a solution.
I just flashed PAC-ROM 4.3 using CWM, and everything seems to be working great.
Than I realized I didn't have a mobile network signal, so I tried placing a call and it said "No mobile network detected".
How can I enable mobile network, cause it's not even in the settings no more?

I have the exact same problem, anyone with any kind of possible solution? Here's what I tried already:
1. Removed both battery/SIM for a minute or more then rebooted. (Also made sure that 2G was off)
2. Called a Koodo tech guy who updated the SIM.
3. Went in store to try and put my SIM in a different phone, SIM worked fine.
4. Lady tried installing a different SIM card (her own), still same problem. Tried a brand new one, still not working.
5. Backed up my pictures and factory reset the phone. Same problem.
6. Took SIM out, and the phone does recognize there is not a SIM card and now the phone gives me the NO SIM CARD message at unlock screen.
7. Updated to 4.3 - Nothing changes.
8. Browsed the internet for hours then cried myself to sleep, hoping someone would help me out eventually.

I had the same problem with revolt ROM. I flashed baseband and wiped all data but nothing changed...
I flash a factory image and it worked
Sorry for my bad english
