I also found this ROM
(it's 4.4.4 despire thread titel). Is there any harm in trying it? I did a backup of the current half-broken system.
You can flash any firmware you want, except the ones for dual sim version (but if you want to be totally safe flash the retail de image). 4.4.4 images aren't available currently, you have simply to restore the stock 4.4.2, flash the stock recovery and take the OTA update.
The ROM you linked is for Moto G dual sim variant (XT1033), flashing it will probably cause a soft brick.
