Hi Sir. First off, you will be happy to know that the Hurricane Rush file itself is tested. What exactly could be the possible cause of your issue will depend on what the issue was that you meant to resolve with the firmware reload or how exactly you proceeded with the flashing process. Like if you flashed the ROM without formating first (especially if the older ROM files were corrupted). Do do this, you click on the Format tab > click Manual format > click Format whole flash (except bootloader) > click Start > connect the device while off > you then get Format Ok. At which stage you can try and flash the device as normal. Only remember to dump the NVRAM first to preserve the IMEI unless if you have some clever way to rebuild Android 6.0+ devices IMEI as they are tricky to root.
