[Windows Central Question]

First off. My whatsapp isnt working. WhatsApp Doesnt even respond . Tried uninstalling And updating it. No use. Then my phone became reaalllyy slow and lags almost every time. Few people advised me to factory reset it. I already mentioned my question.

Factory/hard resetting a phone will not downgrade the software on it.

So yes.

Yes, you will still retain updates received (including developer versions). Otherwise, there would be no need for the Lumia Software Recovery Tool to rollback to older OS versions.

You may want to create a Windows Central account in order to track responses to query easily.

Update: There already is a response to the same post you made earlier, as indicated by Harrie-S.
