all report are ok
You may try another firmware from y91, y93, and y95 to revive this model. But if you only get device vibrate only, then there are no other way, you have to replace both cpu and emmc.
which flash file required
i have y95 need emmc
y11 emmc change file need
If you can't find the dump files for your device,
you may try to write stock firmware directly via UFI eMMC ToolBox in Factory Firmware tab.
But you have to backup the original EFS, so you don't get messed with IMEI Problem.
