Why exactly do I get a "Device is corrupt" message on startup?

I upgraded from 5.1.1 to 6.0 by flashing the factory image without flashing userdata. Everything worked perfectly, but, as many people have noted, I get a "Your device is corrupt" message briefly on startup, before having the opportunity to enter my encryption code. Again, the phone functions just fine despite this.

I'm wondering what it is about my phone that causes this message to display. My bootloader is unlocked, though I don't think this alone should be a problem. I am completely stock, unrooted (though I was rooted on previous versions). As such, I don't think it can be a problem with the system or boot partitions, since, again, I have flashed and re-flashed these directly from the factory image. I don't see how it can be problem with userdata, since this isn't even decrypted when I get the "corrupt" message (i.e., I haven't entered the encryption code yet). Perhaps it's some problem with how userdata is encrypted?

Any logs that might give insight into where the fault is occurring?

Startup company looking for ad free, free webhosting

Hey everyone,

I hope I've posted in the correct forum apologies if I havn't, I am opening a shop soon and I want to host a website, primarily for information purposes to show events newly stocked items etc, money is tight and I can't shell out the £40/50 for hosting at the moment so I'm looking at free alternatives.

I spent 3 hours last night making a page on Wix to finally publish it and have it covered in ads.

Can any one advise me of a good free webhosting site that doesn't have any ads?.

Many thanks

Auto VNC on startup

I have a Lenovo Yoga Tab 3 tablet running Android 5.1.1

How can I setup a VNC viewer that starts automatically on startup and also re-connects automatically when connection is disrupted? In Windows, I am able to achieve this with Bitvise Tunnelier. I do intend to VNC over SSH tunnel.

Any pointers are much appreciated, thanks!
