[Q] How to roll rooted Z back to original state? (TRICKY)
my Xperia Z got damaged and I need to ship it back for service repair. But I already rooted it so I can't apply my guarantee atm. So my question is how to roll it back to the original state that nobody can find out? The problem I am having is that half of my display got cracked (itself - seriously!) and is not responding to any touches (just right half). So after I turn on my phone I am obviously stucked on my own maze lock unable to unlock it. Also I am not able to log in via my google account to prevent the maze lock (can type but the crack is near the button Send so I am not able to send my credentials). Rotating the display doesn't help either. Luckily, I installed CWM recovery which uses only hardware buttons so I should be able to use WIPE DATA/FACTORY RESET option which will wipe the maze lock so I should be able to connect it via Sony Companion. But then I am not sure if I would be able to roll it back to the original state after. I don't know what would WIPE DATA/FACTORY RESET do to root and CWM. Is Sony Companion able to repair/restore my phone to the very original state? Would CWM still be installed on the phone? Would I have a root?
Here is a list of things I did with my Xperia so far after rooting:
- Uninstalled Sony Movies app by Titanium Backup (I didn't backup my phone before - stupid).
- Upgraded to SuperSU Pro (don't think it matters)
- Installed CWM
- Flashed [SOUNDMOD]PureXAudio (I am still able to revert this via CWM and and the stock audio flash)
So I am looking for a best way to restore my phone to the original state before I will send it to the service. My phone is from Japan if it matters to kernel or firmware. If you would suggest me to use some kernel/firmware could you provide me a link please?
Thanks in advance!!!
