Now im aksing you guys to help disabling Hsdpa !
I'm running on 4.4.2 (Jelly Bean) with this ROM : I9190XXUAMF7
I don't think it possible. HSPDA is part of 3G, like a (newer) version. You may switch to 2G completely, but not '3G only' and not going up to HSPDA.
If something like this would be possible, it most likely only achievable by modifying Android's code in one of the file that controls the radio. But not something off the default settings or codes.
