Phone softbricked after updating TWRP My Yu Yureka is stuck at boot logo after I updated to TWRP 3.2.0.0.

It does not go into recovery or download mode. I tried connecting it to PC and that too isn't working.

How do I flash a working version of TWRP to a softbricked phone?
Does the Yureka have Fastboot mode, or the Samsung's Download mode you mean, and if its MTK based, you can read how to flash it using SP Flash Tool via Preloading an Image or Fresh ROM
