Problem with Galaxy mini CSC files....

Okay hi first of all. Okay the problem is that i have this Galaxy mini that was locked to ClaroPR. I used the BML5 method to find the unlock code and it worked perfectly. Problem is that when i inserted a different sim card the phone was not asking for the code. It said Locked but it didnt ask me for the unlock code. So i decided to flash it with a non branded firmware so that i was able to insert the unlock code but for my surprise the phone CSC settings changed. Now i have an unlocked Mini but with no signal. Sometimes the signal shows up but just for a few seconds and gone again. So if someone knows how to solve this i will appreciate your help. Thanks!

Mexico Telcel GT N7000 Unlock for Tmobile

I have Tmobile and I purchase a Samsung Galaxy Note Gt-N7000 from TelCel. Today I received the unlock code for the phone. However, when I insert the Tmobile sim it doesn't prompt me to enter the code. It only says Network Lock and one button to Dismiss. Does anyone know How I can get the phone to accept or prompt me for the code?
HI bud,
there's a similar problem on the other thread. Try to see if you can follow the instructions presented by the posters (on that thread) - >http://forum.xda-developers.com/showthread.php?t=1416175
Note on page #2 and #9 on that thread. It'll greatly help you much.
P.S. Samsung SII and Note share pretty much the same file system so it's safe to follow their instructions.

Note 5 (SM-N920W8) not asking for unlock code

Hi there, I switched from Telus to Koodo yesterday. But, it didn't ask for an unlock code. When I first tried, it was rooted with custom recovery and I thought that might be the reason why it didn't ask for an unlock code. But today, I reset my phone to factory default using Kies Device Initialization option and it still doesn't ask me for it. I tried, #7465625*638*# and it doesn't work. Please help.
Telus OWNS Kodoo, I'm aware this is old but you didn't actually "switch companies" hence why it isn't asking for an unlock code
