software update on a blocked phone

Hi, All,

Can I update software on a blockd phone (IMEI number blocked)?

Thanks,

You may be able to download it from an outside source and flash it through stock recovery. But I don't know the recovery setup for your device, as each oem makes them slightly different.

Since the poster supplied absolutely no info on phone, software version, carrier, etc I simply replied "maybe".
 
You should post the specs of your phone. It's impossible to make a blind comment about this. I'll try to help you out once you reply with the information I need.

You should be able to update by downloading the FW somewhere else though if anything. Just food for thought.
