I am using Microsoft Lumia 540. I updated my Lumia with insider updates from fast ring. Now my phone is showing three problems.

  1. Lock screen buttons are disappeared, that's why I am unable to input 4 digit PIN.
  2. Not connecting with WI-FI.
  3. Not connecting with Cellular Network.

When I connect my phone with charger it automatically shutdowns and starts again and again.

How can I roll back from this update without signing in? OR is there any way to sign in without accessing lock screen???

This issue is fixed in the build 14936. Here is what it says,

  • We fixed the issue causing the pin pad to not be visible to unlock the phone even after rebooting the phone.
  • We fixed the issue where some phones lose the ability to use their SIM cards.


Reference:

  1. Windows 10 build 14936 rolling out for fast ring insiders.
