Undo upgrade w/o root?

KentG — Fri, 01 Aug 2014 07:04:15 GMT

Is there any way to undo the latest upgrade 17.1.2.A.0.314?

After reading all posts I may have to undo the upgrade and return to the previous version (17.1.1.A.0.402)

Regards

download the FTF file, then use flashtool

Doesn't that invalidate the warranty?

I was thinking more of an official way perhaps through the PC Companion...

There is so such way via PCC to downgrade it has to be done via Flashtools as said above by Uli

It shouldn't void warranty. Just find the correct one for your location.

Make a backup of your internal storage though (wiping data partition wipes internal storage as well).
