I used the latest TWRP to flash ZVC and I think it has some issues; has anyone else used it? I wanted to dirty flash ZVC over ZVA but it got stuck and went into a boot loop and it was really hard to get back into recovery. I had to wipe everything after trying for 10 minutes and getting into recovery and then I installed ZVC. Seemed like it was TWRP having issues, maybe the newest version doesn't run well on our phones.
I have had no trouble with twrp but I don't dirty flash unless it just a theme and I definitely wouldn't dirty flash from zva to zvc. But that's my opinion. If you're worried about keeping your info use something like titanium backup for your user apps. Most everything else will automatically install once you sign into Google.
