I used the bootstrap posted here in batches of 10000 blocks. I just needed 3 of them (up to bootstrap161.dat) and the wallet was on ALL day since that and nothing. Still stuck and unable to sync.
I had it on for 20h and not a single block was added.
It only loads from "bootstrap.dat".
You'll need to rename the partial files to bootstrap.dat one at a time, restarting the client after each rename, until it loads those 10k blocks. Or concatente the partial files together into a single bootstrap.dat. The client won't open files with names like bootstrap-123.dat.
