I wanted to root my Lenovo Tab 4 10 tablet, so I installed TWRP successfully but then my internal storage was showing up 0 Mb. So I use OTG (Pendrive) to flash SuperSU zip. Then it was stuck on mounting, so I switched my tab off. Then I even factory reset my tab via TWRP and recovery mode. But now it is stuck on the boot logo and doesn't boot up no matter how many times I reboot or factory reset it.
I even tried flashing the stock firmware. Still got no good results
I don't have access to USB debugging or TWRP now.
