Hey guys. I reverted back to stock after I installed Mahdi because my gps wouldn't work. I was able to get the GPS to work in the stock ROM and then I wanted to re-flash Mahdi. I rooted with ioroot, installed autorec, went into twrp and installed dr87 184.108.40.206, then I installed Mahdi. After installing Mahdi when I try to boot I get the fastboot udc-start, screen, I can get into recovey and download mode but I cannot get mahdi to boot. How can I fix this because I absolutely HATE the stock rom. Thanks guys.
