Help OTA Update Not Installing (Lenovo Tab S8-50F)

Hi,

So basically. I'm having trouble with my Lenovo Tab S8-50 installing OTA updates.

The OTA downloads fine, and then, when it comes to installation, it bails out instantly in the recovery menu with the following text down the bottom

Code:
Finding update package...
Opening update package...
E:failed to map file
Installation aborted.
E: can not create '/data/ota' : Permission denied

I've recently got this tablet back after a repair (Took it to the retailer, who then sent it off for repairs, so it's official), and this is really frustrating me because Lollipop has a fair few bugs which really need fixing (Some apps do not open, I think this is due to the app, but other bugs include landscape mode not working on the stock launcher, the whole Dolby EQ thing bundled with the tablet just straight-up not working, and displaying the "Update successful" message every time i restart the tablet).


One other thing which is a bug that arose in the most recent update i can actually install. Whenever i boot the tablet, the following message displays

Code:
ERRLINUX_ERROR [uefi_get_simple_var] Failed to get variable WDColdReset

Any help? (It shouldn't be rooted and it is still well within warranty. I will run a root checker of course, in case something happened during repair. I am doubtful this is the case, but it would explain the refusal to accept the update)
