Asus memo pad 7 K017 won't install system update

[HarshJam]

So in the beginning of January this year I thought I'd update my tablet since it had been pestering me with the notification so I did update it only problem half way through updating it said "error" ever since then whenever I boot it up it just tries to install the update but always shows "error". I've tried a lot of stuff that I'd used in the past when it broke but nothing works, I've updated the system in the past and it's never broke.
