[Q] OTA update or LG Bridge on rooted device?

Hi,

I have a rooted H815T on v10B.
I am going to upgrade to v10C.

Is it possible to do OTA update for my rooted v10B?
If not, Is it safe to do the upgrade via LC Bridge? Does it wipe my data?

Thanks!

Wifi and Hotspot at the same time? (wifi bridge)

Hello,
I have an Xperia-Sola with root access and KitKat installed.
I'd like to extend my wifi network (from router) by using Xperia Sola as a wifi bridge device.
To do this I would need to enable both wifi (to catch my router connection) and hotspot (that's wifi-tethering, to 'bridge' the router connection).
So,
Is it possible to enable Wifi and Hotspot at the same time?
Thanks in advance
