Greetings friends,

It is my first post and I hope not to break any rule, the problem I have with my cell phone has me somewhat desperate.

At the beginning of December the cell phone received the update and after applying it the cell phone does not activate the SIM Card, it detects it but shows no signal, I have tried everything and I have not managed to solve the problem, my last option is to flash the cell phone but the Bootloader is blocked; Someone in the group will have knowledge of how to unlock the bootleader without the SIM card having a signal or without it being present in the cell phone, I need to recover the cell phone.

Thank you in advance for the information you can provide me.
