My a1000 tablet won't power on

My a1000 tablet stuck on logo and then i downloaded the firmware to flash (i don't know what a1000 exactly but i flashed it with a1000-f)

After flashing, I can't turn on the power

When I plug in the charger it still works but when I turn it on, it only shows the lenovo logo for a while then turns off and goes back to the charging screen.

I also can't get into recovery mode but I can still get into the bootloader

Can someone help me in this case?
