ZVD downgrade details
Reference
If you currently have Xionia CWMA Recovery v1.2518.6 (do NOT try this with thunderc recovery), you can save yourself the step of (re)installing stock Recovery before installing the ZVD update.zip in the following situations:
Note #1 - If at any point your phone gets stuck on the Android logo, do a Factory reset from within Stock Recovery
a) [Radio: ZVD] / [ROM: any] => stock ZVD Radio/ROM/Recovery
From Xionia CWMA Recovery, use "install zip from sdcard" and turn off "signature verification", then use "apply sdcard:update.zip" to install the ZVD update.zip
b) [Radio: any] / [ROM: any] => stock ZVD Radio/ROM/Recovery
In this case, we will install the ZVD update.zip twice. The first install gets you stock ZVD ROM/Recovery (with your existing radio). Data likely won't work at this point. The second install then adds stock ZVD Radio. From Xionia CWMA Recovery, use "install zip from sdcard" and turn off "signature verification", then use "apply sdcard:update.zip" to install the ZVD update.zip. After that is done, boot into Recovery and "apply sdcard:update.zip".
c) [Radio: any] / [ROM: any] => rooted ZVH Radio/ROM/Recovery
In this case, we just install the ZVD update.zip in Xionia CWMA Recovery knowing there will be a Radio/ROM mismatch and data likely won't work. We don't care because we are just going to root the ROM and go back to ZVH. From Xionia CWMA Recovery, use "install zip from sdcard" and turn off "signature verification", then use "apply sdcard:update.zip" to install the ZVD update.zip. Next use [GingerSnap] [GingerBreak] to root ZVD. After that follow the ZVH rooting steps.
