Yes there are people working on downgraders but you never know when they're going to release, could be tomorrow or in 2 months nobody knows. Just stay at 3.11 and don't update, then when a downgrader comes out use it then get 3.10 OE-A' custom firmware. Or whatever one is out by that time, it's great though all your 3.10 capabilities with all 1.5 homebrew!
