Unroot using sony pc companion

[coletrickle79]

HI guys

im currently running slim rom 4.4 on my z1 with unlocked bootloader. im looking to wipe and unroot, the guides ive seen are not to straight forward, im pretty much a complete noob and not very tech savvy, and a little worried about bricking my z1.
recently i connected my z1 to the laptop and sony pc companion auto ran and siad i have an update {157 firmware} for my z1, if i were to go ahead with this update would i brick my phone or would it wipe and be back to factory rom and would root be lost

For unroot, Simply connect your phone to pc and do "repair" in pc companion.

Edit: you lose your data after repair.

If you do repair then it will have a reset. I'm not sure if the repair does update your firmware as well, but I don't think so. And I think the bootloader will still be open. You must relock it before, but again I'm not 100% sure with this.

Edit: if you take out SD card, it can't be deleted. But the internal storage of your phone will be deleted.
