Unlocking sim card after firmware flash not working - Galaxy S II Q&A, Help & Troubleshooting

Hello,
i have a huge probem with my i9100 - i got my usb port repaired - got it back with a stock firmware - (before CM10 M3/DorimanX Kernel)
I just used it a few minutes and started flashing CM (with CM Installer).
Since that i cant unlock my Sim - it shows "Unlocking sim card...." and after a few seconds sim pin screen appears again.
I already flashed a backup by CWM (from pre USB port repair) and the same problem here - i have no idea how to fix that

nobody with an idea?

Neo (MT15i) SIM card not recognised - Help please

Hi, not new to rooting etc. (have a ZTE Blade which have rooted & custom rom in past).
Have inherited Xperia NEO. Was on 2.3.4 stock & locked to UK O2 network. Now does not recognise SIM card (OVIVO on UK Vodafone network) at any software version 2.3 or 4.x.
Have used flashtool to get to 4.1.B.0.587 - fine.
Rooted with DoomLord - think it worked OK.
Tried unlocking with PlasmaTool - had to short a couple of pins to put into test mode. Tested it recognised the phone but did not go any further. Think this is what screwed it up.
Have since got SIM unlock code from O2.
Have also tried 'RESTORE' in S1tools (found in other threads) & reflash but still not working.
Any help welcomed please - how can I get phone to recognise SIM again ? Thanks
Fixed.
If it helps anyone else - I wasn't using the S1tool correctly.
Clicked on Identify, connected phone as directed, clicked on RESTORE. then have to disconnect & reconnect phone as directed. Then says Restore Complete.
Inserted other network SIM - booted phone and prompted for Unlock Code.

I9100 No SIM card/no IMEI/Unknown Baseband

Hi!
So I have this problem with my Samsung Galaxy SII that it doesn't recognize the SIM card for the most of the time. When this problem started, the phone was completely stock (Not rooted/Not a single flashing made by me). Android version was the latest official 4.1.2.
Problem description:
I could be using the phone completely normally and then suddenly it reports that there is no SIM card. Now with pulling out and putting back the SIM card and rebooting couple of times, it might recognize the SIM card again and work for a while (few hours).
What I've tried to fix this:
1. Tried the SIM card on another phone, it worked perfectly.
2. Tried another SIM card on my S2, didn't work any better.
3. I thought that as the warranty is over, I might aswell just root my S2 and install the CyanogenMod 12.1 and check if this fixes the problem (Well it didn't).
4. I saw that my IMEI number shows nothing so I did this: [GUIDE] Recover your IMEI in 9 steps..
Well step 4 didn't bring back the IMEI number but now after rebooting a couple of times when I got my SIM card to be recognized again and then checked the IMEI, it was correct. Though the SIM card wasn't detected after a while again.​5. Well now I flashed back the original Android 4.1.2 and checked the IMEI number (SIM not detected), it showed "null/null".
6. I went back to CyanogenMod 12.1 and saw that when it's showing blank IMEI, it's also showing "Baseband version: Unknown.
7. Flashed a new Modem+RIL, not helping either.
8. Tried many other things which I can't remember now but found by googling.
So it's sometimes working and also shows the correct IMEI and baseband and sometimes they are all gone?
My question here is that is there anything I can still try to get it working. And also if anyone knows where the problem could be? Is it some part that is faulty or is it the software that is messing with me? I'm quite handy at taking apart and changing the parts inside if that is the case. It's just that I'm not going to pay over 100€ for a new motherboard to get it fixed.
Thanks for any replies!
