i download two ROM and extract with new version of winrar. change usb port a lot of times, install manualy mtk drivers, start windows without autentication drivers, try with another pc. NOTHING!! same problem hash_mismatch.
may be that panicked you did not notice that the phone is unloaded at 0% and you can not access ame and happened with another phone umi try to keep it in charge make a verification
