Phone updates after replacing motherboard

[Revanth]

I have been reading three threads regarding they are not receiving updates after motherboard replacement . Please let me know that are there anyone who is getting updates even after motherboard replacement or we will not get updates after motherboard replacement . Please reply those who have replaced their motherboard
And please mods reply if you know any of the people who replaced motherboard have received updates that's not a big issue?

If you aren't receiving FOTA updates, you can always manually download and install the firmware from the support site.

If you miss out on multiple FOTA updates, then you should contact your local Support to verify that your IMEI is still correct.

Local support in the sense? Service center?

You should be able to call or email them, and they can check remotely. A service center visit might be necessary.
