[Q] Change CSC code loose unlock? - Galaxy S II Q&A, Help & Troubleshooting

Hello. I bought a Galaxy S2 and it was unlocked by with the app Galaxy_S_Unlock. Everything is fine, but now I can't make updates through Kies.
I think the problem is that the rom is 'TPH' and the csc code on the phone is 'OPT'.
O know that I can change the csc code with *#272*Device IMEI#, but my question is: with that operation the phone will hard reset. I will loose the unlock?
Thank you.

[Q] CSC change???

Hi
I'm not sure if this has already been answered on here so please forgive me for asking again if it has,
I bought a samsung galaxy S3 in the UK, and I am going to South Africa next week and wanted to give the phone to my sister, was wondering how to change the csc from UK to the South African network.
I will explain, when I bought the phone, it is a 3 network mobile, I put my vodafone sim card in and it said "sim unlock pin"
I rooted the phone, bought the voodoo unlocking software and it seemed to do the trick, so now when i put my vodafone sim card in, it doesnt ask for a sim unlock pin anymore, and if i go and look in my available networks i see a whole load of networks for example the list looks like this
Vodafone UK(3G)
current network
vodafone UK(2G)
Available Network
T-Mobile Uk(3G)
Forbidden Network
and so on,the list goes on, i only have Orange that also says available network, the rest say forbidden network.
When I type *#726#and my imei number, press the dial button, it doesn't do anything but comes back and says "not registered on network"
Can anyone please help me??
Thanks in advance
Its *#272*Device IMEI# be careful. This wipes your device.

you can't change csc in a single csc rom! it works only in multi csc roms!
i think you have to change rom to have network working properly...
You need to flash a rom from south africa (just look up sammobile.com for the fitting file) in order to choose an south african CSC the way it is mentioned above.
By the way:
You said, you used voodoo sim unlock? After flashing one of the incmoing Jelly Bean Roms the Simlock might be active again!
Voodoo doesn't work on JB Roms.
You might want to simunlock you're phone using this method again: http://forum.xda-developers.com/showthread.php?t=1846451

[Q] Missing CSC - Sim-locked

I have the Samsung Galaxy S II i9100M, which is the Bell Mobility (Canada) variant. Same hardware as the i9100 and capable of running roms for the international version; only difference is the crapload of bloatware Bell Mobility had installed on it.
Though a Canadian phone, the phone worked well using a T-Mobile SIM here in the US. After tinkering with Odin and a couple of ROMs I flashed the phone from a stock Gingerbread ROM to a leaked version of Samsung's 4.2 Jellybean ROM, made for the i9100, a couple months before the update on Kies was ready. Unfortunately, I sim-locked the phone, the cause I assume is a missing CSC file.
Does anyone know how to fix this problem? I have been told already by one phone unlocking company that to restore the CSC file I have to flash a new one. Will I have to flash a ROM with the proper CSC file then have someone unlock the device with a sim unlock code or can I just flash a CSC no sim-unlock needed? I NEED HELP PLEASE!!! I screwed up, and it's really annoying having a smartphone that works for everything but making phone calls or texting (the irony).
PICS I HOPE WILL HELP ARE ATTACHED

[Q] Travelling to Indonesia. About CSC Codes

Hi,
I'm travelling to Indonesia this summer and want to use an Indonesian SIM whilst I am out there. Using GalaxSim, I can tell that my phone is network unlocked, however it says that CSC Lock is 'locked'. I live in the UK and know the CSC on my phone is BTU, as I has previously flashed with a BTU firmware.
So two questions,
a) What does CSC Lock 'locked' actually mean?
b) Will I be able to put an Indonesian SIM in with no issues?
Thanks.

CM12, Simlock - cannot unlock phone, Galaxy s5

This has been asked and answered many times. You need to have a stock based rom to input unlock codes.
