I want to change my rom to Chinese rom, so I downloaded the rom and sp flash tools, I clicked on download on sp flash tools and plugged my phone to the computer and I got an error message saying PMT changed rom must be downloaded. I search for a solution and I got it, which was to change the download on sp flash tools to firmware upgrade, which I did and tried the flash tools again. I got another error message this time, it was Brom Error. After that I tried to boot up the phone, it didn't respond, I tried charging it, it still didn't respond.
It's been 2 hrs now, and my phone has not booted up yet. Please help
