I posted this in the other thread:
I unfortunately could not replicate your wifi problem. One note is that most MOJOs that have been made available should have already been on "MO0110-WW", so this step could be skipped if you don't need it.
Before any update, you can also go into your google account settings, choose your account, and then choose "Sync now" from the menu in the top right. If wifi is not working, you can use a wired ethernet connection to at least do this step. If you're forced to do the "factory reset" option to fix the wifi, when you do the initial setup again, choose to "restore" from your google account. Outside of apps that have been sideloaded, this should start downloads of everything that was downloaded from the google play store shortly after the initial setup is finished. You can check which ones are being re-downloaded by going into the Play Store and then checking your "My apps".
