Last month my phone (YU YUPHORIA) stopped booting up.. so I went the "customer service center" and asked the guy maybe he can install new software. He tried and said we can't repair it.
I love this phone not the best performance phone but I love it. So I don't want to throw it away. So yesterday night I started searching how to install custom ROMs. and found a development mode build for my device. After some tutorials and experiment it's up and running baby... 📱😍. Thank you internet for helping me..
