Hey, so I got this problem with the original HTC one SV (european version with SIM card model) and had to get another logic board. Ordered one from ebay and it has finally arrived. Now the problem is - that this HTC ONE SV from USA is Boost version with 4G LTE and it has no sim card slot, pre-programmed sim card literally inside of the phone. However, I took off the sim reader and unplugged it from the old PCB which is easily done, and replaced it on to the new working PCB. now if I start my phone it will ask for the PIN code, it does recognize the sim card from the other phone sim reader that I have attached, but it does not pick up the signal. And if I go to settings menu in about section it still shows old pre-programmed phone number and not the new one.

How do I go about reprogramming it to EU version official HTC ONE SV? Hope to hear some suggestions.
