My phone is on a bootloop now (a really short one) and I tried installing the backup boot.img using windows 10 powershell but it says the device is locked, when i try unlocking it it says unknown command, but the command is there when i type "fastboot help".
I tried using qualcomm's flashing tool but it gives me a horsething fail.
Help, i'm on really low budget and I want to fix my phone asap. Thank you.
Phone is Infinix Hot 3 LTE (x553) and the tool i used to flash it (before the disaster) is android Flashify.
