Just check my device's bootloader status and it's still unlocked. I got exactly "zip file is corrupted" error but I had re-downloaded 5 times. Don't know what's happening :(
What's your mi5s version? Did you update through updater or twpr? This is the first time I got this error because updating went smoothly for the all previous rom except this one. Don't know how to solve.
Can anyone update successfully for mi5s? After decrypting rom, press the pop-up to confirm update but nothing happens. Use twpr to update manually but get zip corruption error. I have downloaded 5 times but got same result. Mine is mi5s 128gb.
