[Q] [i9305] Phone not registered on network issue

hello xda !
I'm a C developper who just received his brand new Galaxy S3 i9305 4.1.2, my first android device !
And i love android. But i just realized it's simlocked and my provider bills 170€ (200$) to get an unlock code !
As i don't have that money and i don't wanna spend it unlocking my phone, i decided to downgrade my i9305 to 4.1.1, and to use the desimlock trick. I did it, using my provider ROM (i'm pretty sure it's the right one). My phone seems to be unlocked, but when i tried to do a test call, i got a weird message:
"Phone not registered on network"
WTF ?
I had a hope when i found ARIZA patch, but it failed, it was made for i9300.
I googled it again for a few days, and i found out that it probably is its modem firmware.
I'm not even sure of it and I hesitate flashing it back to 4.1.2.
Any idea of what causes the issue and how to solve it ?
I'm currently using XXALK2 and i'm from France using the Bouygues network, if it helps
Thanks for your help and time, this is my first post here.
