Finally, push the pkgs directory to the phone with iutool.

In my first test, these packages are missing, I'll see if I could grab them individually:

Microsoft.HoverFM.spk*
Microsoft.MS_NETLOG_RETAIL.MainOS.spk*
Microsoft.PRERELEASE_PROTECTED.HT.MainOS.spk*

While HoverFM and PRERELEASE_PROTECTED.HT.MainOS exist in later OS updates, MS_NETLOG_RETAIL doesn't exist in later updates.

I've been told the touch screen could be unusable after update, so please connect a bluetooth mouse (if you have) before you update.

I'm creating Offline Update Package 2 to 10586.1176, 14393.1066, 14393.2551 and 15063.297.

In case you want to restore the phone back to original, thor2 will help:
