My IMEI number has disappeared on my Nexus 5 and now I can neither call nor text.

Status of the phone says:

  • Network: Unknown
  • Mobile network type Unknown
  • Service State: Out of service
  • Mobile network state: Disconnected
  • My phone number: Unknown
  • IMEI: Unknown
  • IMEI SV: Unknown

All of this happened after updating to Lollipop using bootloader.

I have tried several tutorial videos, such as:

  • "How to Unroot Nexus 5 on Mac! - Restore to Complete Stock",
  • "How to Upgrade, Downgrade, Restore ANY NEXUS Device on a Mac - Easiest Method"

Now is my Nexus downgraded to Android 4.4 and I can't text or call anyone. When I try to open the Camera I get the message "Unfortunately camera has stopped". The same thing happens with Google Play Store.

When I try to take a screenshot I get the message "Couldn't save screenshot. Storage may be in use." It's like it can't connect to the storage.

Can I fix this? Is it possible to restore the IMEI without any backup?

If not, should I lock the bootloader and send it to my carrier (I live in Sweden)?

Note: I have the IMEI number written down.

There is nothing to worry. Please follow the steps mentioned in this Android Enthusiasts answer.

You just have to flash the images properly. Do a factory reset using the recovery mode.

  • Volume Down + Power
  • Bootloader screen will be visible
  • Go to Recovery
  • Power + Volume up key (few seconds) and then let go of the Volume up key, but keep pressing Power
  • Select Wipe Dalvik cache
  • Select Factory reset
  • Step 1 should be Volume Up + Volume Down + Power instead of Volume Down + Power – blvdeer Jan 8 '17 at 16:58
