Hi, a friend of mine has a Galaxy Tab 8.4", which was bought three months ago and obviously came with Kitkat. He accidentally upgraded it to 5.0.2 (if that is possible), as now the interface is not dark, but white with blue fonts and such. I looked everywhere on how to downgrade to Kitkat, as he does not like the new interface. I found several guides, it seems easy, but I could not find any 4.4.2 ROMs for that particular machine, all download links were either bogus, or offline. Can one contact Samsung to deliver the old ROM, which I think is not possible, they might be like Apple that way, or is there an official or even unofficial way to obtain the ROM?
