XT1092 Bootloader unable to re-lock. Need to get replacement

Hi, i recently ordered my moto x 2014 32gb from flipkart(just in case this info help). The Model number is XT1092. I did bootloader unlock and flashed cyanogen mod. It is my mistake i didn't backup my factory images. Now i want to return the phone to flipkart. I restored my phone to factory settings using RETEUALL_XT1092_5.0_LXE22.46-19_cid7_CFC.xml image. I then did fastboot oem lock...but it gave me two errors
1. sst failure
2. need to do fastboot oem lock begin.
I did the lock begin command and flashed firmware but it resulted in failure stating PreFlash Verification failure. Please I need to return this phone, I dont want to use it anymore but i need to first lock the bootloader. What should i do.

updating XT1092 4.4.4 to 5.1 and root ?

Hi guys,
I have some questions about updating my new XT1092 :
I'm french and have a 4.4.4 android stock version deutsch (21.21.45.victara_retde.retdeall.en.DE retde)
I haven't made modifications (bootloader not unlocked) or update to keep maximum root possiblilites.
i want 2 things : update to lollipop 5.1 and root my phone.
But after reading some posts and brick problems, i don't know where to start :
does i need to update to 5.1 first and root after ?
or root first on 4.4.4 version and update to 5 and 5.1 ?
OTA update or manual update ?

Thanks!
