Hey Steven, I'm having trouble again. I had my wallet closed for a few days and when I start it again it won't sync. It's trying hard to stake or sync, it goes forward a few blocks and at some point remaining blocks seem to increase.
The bootstrap you provided, just to be sure, is for replacing the blk0001.dat file, right? I tried it with a clean installation but it doesn't work, starts from block ~700k.
I also tried a clean install, let it sync and only replaced the wallet.dat file afterward but only a quarter of my coins show up.
How do I prevent it from staking when I start the wallet, I'd like to try it, see if it helps. You mentioned putting in the config file 'staking=0'. Is that file config.ini because I've already tried it but nothing.
 I can't figure it out .
