Default [Q] Debrand Asus Transformer TF700KL - Vodafone

I would like to debrand my Asus Transformer TF700KL (the one with 4G/LTE), I've got root access and did a search with Root Explorer and it came up with a lot of entrys containing Vodafone. (And here I would like to attach a screenshot, but seems the only option is to upload it somewhere and provide a link, maybe I'll try it later).

I'ts not sim-locked, I'm using my own ISP's mobile network, but I want to get rid of all the Vodafone stuff, like splash screen, lots of apps and background services.

I guess I can't just delete what Root Explorer found, is there another way? New stock ROM? From where? Can't find a CM (only for TF700T), can't unlock the tab (it's running JB 4.1, the unlocker provided by Asus works only on 4.2)...

Any solutions would be appreciated, surely not only by me...
