    I've a Lumia 540. I needed to downgrade it. So, I connected the phone with pc via usb cable. While the package was being downloaded, I disconnected it to use. When downloading finished, I reconnected it to recover. But after a little bit installation of the package, PC showed me a message ''Operation unsuccessful''. Then I disconnected my phone and removed the battery. After a little, reconnected my battery and pressed the power button, but didn't turn on. Then I connected with charger, nothing happened yet.

    Please kindly tell me what to do now? Will it be recovered again?

    Have you tried to connected to the PC and windows device recovery tool again? Maybe that could help? But I don't know since the phone cannot turn on, I hope that will work.
