Camachado, what methods have you tried to write IMEI after flashing NVRAM?

If use the MTK droid tool, try to enable USB debug and get root shell permission in mtk droid tool. It normally not required, but could help if you're having a problem getting the IMEI to 'stick'. after finish write, reboot phone.
