Toggle Sig verification in the safestrap menu.
Nope. Same result. But this is interesting. Previously I was downloading via the link in the lower right of the page that says "Download all as zip", and it went pretty fast. This time I clicked the big ZIP button in the middle of the page, and it took much longer to download, and the MD5 matches up. The file size is also different by 1K. So somehow that other link is downloading a bad or different file. This is on "minus".
I have the private ROM now, and I'm re-downloading the ABYSM and UI files.
