Question [Q] HELP to REVERT Stock firmware (Recovery)

Hello, actually on my P6 I have Omni Rom 4.4.2 (this one http://forum.xda-developers.com/show....php?t=2673839 )

I have some hardware problems with my device so I want to send it in WARRANTY, so now I need to return on stock firmware and revert to a stock boot+recovery+rom

Is this the right way to REVERT all to stock? :

1. I need a boot.img (a stock one, I think B118, it is a good rom for warranty?) <---- where to find it
2. I need a recovery.img (a stock one, B118? ) <---- found this (http://www.androidfilehost.com/?fid=23252070760973625 )
3. I downloaded a stock rom B118 on my SD (dload/update.app)
4. Have I to UNROOT my device?

Thank you very much

Now I've installed a Custom CyanogenMod unofficial on TWRP, no problems with zip firmware update or downgrade, but actually impossibile to install an official update/downgrade (update.app)

Dowloaded a stock B118
inserted it on SD in dload folder
rebooting (vol+)+(vol-)+power
initially has started the flashing process, but after a second appair FAIL...

any suggestion?

You need to flash stock recovery image to be able to install stock ROM by dload method.

To reverd from KitKat to Jelly Bean first install that: https://mega.co.nz/#!9oEHUTiR!uVKEq6...QZ5yrnedx4rug4 via dload folder, after that install 4.2.2 stock firmware again via dload folder. That is a middle step, without it you can't downgrade from KitKat to Jelly Bean.
