Help How to fix 'Encryption Unsuccessful' error in LYF wind 6?

[Dinesh Pitale]

Phone model : LYF LS-5009 (wind 6)
Problem : Unable to boot in system due to Encryption Unsuccessful Error

Things i tried to solve this problem : 1) Reset the phone from recovery mode ( wipe all data)
2) Wipe all cache
3) Installed Software again ( firmware flashed)

I saw one more error in recovery mode UI : E: Failed to mount /cache (Invalid argument)
E: Can't mount /cache/recovery/log
E: Can't open /cache/recoveryg
Etc............
I am attaching all the photos of problem here.
