[Nexus 7 (2013) Q&A] markusb68:
Hello,

my N7 2013 Wifi suddenly rebooted and now it's stuck at the google logo.

The bootloader was unlocked so it also shows the open lock symbol.

Can enter bootloader and boot twrp. But it can't mount any partititions.

Any chance that EMMC is not dead?

Can a gpt reflash help?

Here are the logs:
