Datastore boolvalue not working?

I'm not exactly sure what your intentions were with this script but:

First of all you cannot save a table. You will have to use the JSON format. Also you try to compare a boot value to 1. Third you never actually load any value.

Your script:

game.Players.PlayerAdded:connect(function(player)
    local store = game:GetService("DataStoreService"):GetDataStore("awesomedata")
    local key="user_"..player.userId
    local BV = Instance.new("BoolValue",player)
    BV.Name = "lol"
    BV.Value = store:GetAsync(key) or false

    BV.Changed:connect(function()
        store:SetAsync(key,BV.Value)
    end)
end)

Your script saving multiple values using JSON.

local Utils = LoadLibrary("RbxUtility")
game.Players.PlayerAdded:connect(function(player)

    local store = game:GetService("DataStoreService"):GetDataStore("awesomedata")
    local key="user_"..player.userId

    local BV = Instance.new("BoolValue",player)
    BV.Name = "lol"
    local BV2= Instance.new("BoolValue",player)
    BV2.Name = "lol2"

    Save = store:GetAsync(key) and Utils.DecodeJSON(GetAsync(Key)) 

    if Save then
        BV.Value = Save[1]
        BV2.Value = Save[2]
    else
        BV.Value = true
        BV2.Value = false
    end 

    function SaveValue()
        store:SetAsync(key,EncodeJSON({BV.Value;BV2.Value}))
    end
    BV.Changed:connect(SaveValue)
    BV2.Changed:connect(SaveValue)
end)

An automatic DataStore script.

local Data = {
    ["Bool Value 1"] =  {"BoolValue"; true};
    ["Points"] = {"IntValue"; 100};
}

local DataStoreService = Game:GetService("DataStoreService")

Game.Players.PlayerAdded:connect(function(Player)
    local UserId = Player.userId
    local Folder = Instance.new("Folder",player)
    Folder.Name = "Stats"
    for Name,Info in pairs(Data) do
        local Type, Default = unpack(Info)
        local Store = DataStoreService:GetDataStore(Name)
        local Stat = instance.new(Type,Folder)
        Stat.Name = Name
        local Save = Store:GetAsync(UserId)
        Stat.Value = Save or Default
        Stat.Changed:connect(function()
            Store:SetAsync(UserId,Stat.Value)
        end)
    end
end)

local one = true --consider using local variables
local two =false

game.Players.PlayerAdded:connect(function(player)
local store = game:GetService("DataStoreService"):GetDataStore("awesomedata")
local BV = Instance.new("BoolValue",player)
BV.Value = false
BV.Name = "lol"
local key="user_"..player.userId
store:SetAsync(key, {one, two}) --ok so we set {true,false} to the datastore with key
local function unscramble(input) --consider local function
if input==1 then --input in this case is a table, not an int.
return true
else
return false
end
end

local content1=store:GetAsync(key) --returns the value of key in the datastore 'store'
local unscrambled=unscramble(content1) --here's your problem, content1 is a table, not an int.
end)

content1 would equal {true,false} so i don't know what you want to do with these bool values, but implement it into your code.

Some code I used to save a BoolValue.

Note that it isn't under typical "leaderstats" value. Simple edit though.

function onPlayerEntered(player)
wait()
player:WaitForDataReady()
repeat wait() until player:FindFirstChild("Player_Preferences") --Change to where you BoolValue is parented under
if player.DataReady then
if player:findFirstChild("Player_Preferences") then
local score = player.Player_Preferences.Reset --BoolValue.Name here
local ScoreLoaded = player:LoadBoolean(score.Name)
wait()
if ScoreLoaded ~= false then
score.Value = ScoreLoaded
end
end
end
end


function onPlayerLeaving(player)
if player:findFirstChild("Player_Preferences") then
local score = player.Player_Preferences.Reset
player:SaveBoolean(score.Name,score.Value)
end
end

game.Players.PlayerAdded:connect(onPlayerEntered)
game.Players.PlayerRemoving:connect(onPlayerLeaving)
