I've got a t0lte. I've been using the H3G image for it for a few months, with no problems with the network apart from not going onto LTE, and massive problems with Bluetooth (it seems Samsung suck at it). So I installed OmniROM 4.4.2. After a few days, I started getting up to 50% packet loss. I switched to CM11, same thing. Then on to SlimKat, as someone on #omnirom suggested it might be the RIL, but it wasn't that. I tried two other modems, didn't help. I then tried OmniROM 4.3.1, same thing, and CM10.2, same thing. Tried the latest modem I could find, XXUENA1, same thing.
People have suggested it might be a carrier issue (I'm on H3G), but I can't fathom how. I don't experience any packet loss on the stock H3G image I downloaded. But now they are rolling out LTE, I need something that can get on it.
I've hunted through the interwebs and can't find anything matching this.
Can anyone help?
