[Q] Proper Method to Unroot and Remove all flags? topic

I want to make my m8 turn back to stock so I can claim the free screen replacement

I am rooted, and currently S-Off with the sunshine method.

So the first step would 've to flash the firmware following this guide

First I would have to relock the device with the command "fastboot oem lock"

Then I would open the executable file in this guide to flash the RUU (I have T-Mobile):

Then I would enter this( My boot loader doesn't say tampered as in the guide, since I have a newer version, it says software modified, I assume it would still work)

Code:

---

adb devices
adb shell
su
echo -ne ‘\x00′ | dd of=/dev/block/mmcblk0p6 bs=1 seek=5314564
exit
exit
adb reboot bootloader

---

from this guide:

Then to relock the device I would follow this

Code:

---

adb shell
su
echo -ne ‘\x00\x00\x00\x00′ | dd of=/dev/block/mmcblk0p2 bs=1 seek=33796
exit
exit

---

then

Code:

---

adb reboot bootloader

---

And then set s on. Should I reflash again? Just to make sure so I don't accidentally brick it?

"fastboot oem writesecureflag 3"

I just want to know if I'm doing this correctly, I'm pretty new to android.
