I can post a copy of my blockchain files. I am at block 326148 now, I have used this files to sync other wallets in other pcs and this works fine.
You can backup all your actual chain and wallet and try this files.
What Do You think. Do You want this files?
For now I am using a windows wallet, it works for v2.1.2 and v2.1.5 versions.
Yes that would be great. It's been laborious not being synced as the problem just goes on and on. I said in my posting above that I've been working on this for weeks but the reality is it's been months. I haven't been synced since early December.
Please let us know as soon as you've put the bootstrap up somewhere for download.
