My YU YUPHORIA got bricked while I was working with it. I want to install custom ROM into it for that I am installing custom recovery and boot file but the file that is found on Internet was not working and that's why I am stuck with company logo. I can't go into recovery mod, neither it boot, and USB debugging mode is turned off. I tried to install fresh ROM from fastboot but after installing every driver properly command prompt is showing "waiting for the device". Please sugest some way to get rid of this problem.
Flashing stock firmware may solve the softbrick. Download firmware fron this link. - The link is for model Y5010a, since you didn't mention which model. Update with model name if it's differ.
There is 3 files, in zip format. Choose any of them, unzip it and you'll find drivers, the flash files and the flashing instructions. Install drivers and your phone should be detected.
