HTC Desire Eye comes with great hardware, but it would be excellent if you give it root access. You will be able to do a lot of things like changes the UI and remove bloatwares, you even have a chance to flash a custom ROM which developed to boost the phone’s performance. However, if you ever change your mind and want to restore your phone to its original state, you can easily unroot and restore your HTC Desire Eye back to stock.
It’s good to know that we can return the HTC Desire Eye to stock condition after doing a lot of mods on it. Thank goodness, HTC offers an RUU for this purpose. The HTC ROM Update Utility (RUU) usually offered in Windows executable or zip file, for the executable RUU, we just need to double-click on it then follow the onscreen instructions. After that, your smartphone’s software will return to stock, of course with an irreversible change like RELOCKED status on the bootloader mode.
Then, if you have replaced the stock recovery with the custom one like TWRP recovery, you will need a stock recovery for some time, specifically if you wish to install the new software update via OTA which you might get it sooner or later. Since only stock recovery can install the official software update from HTC, this does not apply if you’re running an AOSP ROM.

In case you are planning to use an RUU to unroot and back-to-stock, make sure that the bootloader is LOCKED or RELOCKED, so check it by booting into bootloader mode. Since, it is likely that the RUU will refuse to flash your device with an UNLOCKED bootloader.
Here’s the command to relock the bootloader, but put the phone into fastboot mode first:
When a new software update is coming and you need to revert to stock recovery, run the following command. Make sure the stock recovery file located in the same folder with the fastboot files.
