The 7 pro and 6 are the ONLY phones I have had the experience of saying they do NOT need to be rooted..
It will record phone calls. It will come straight out the box with the least amount of bloat I ever seen. Also once Its bootunlocked I hear that some things will stop working like google pay. Its also a gamble to root cause its very new. I havent found a reason to root it.. The phone is a beast and really is super clean in and out.. I surely hope I can figure out WHY is not getting 4g and 5G on ATT

Can someone confirm if I unlock the bootloader (only to install TWRP for emergencies) will I lose OTA updates?

Because that's what I understand from the warning in the unlocked apk.

Thank you

From experience with Asus devices , you will loose Ota updates if you unlock with official tool. What happens generally is that the serial number of the device is sent to Asus servers through the tool to stop sending updates , only manually. You can unlock unofficially if there's the possibility.

I unlocked the bootloader using the unlock tool from Asus and it works (@dogoku I did lose OTA updates, but manual updates work), but now I want to relock it. I tried "fastboot oem asus-back" but it returns the error (along with any other fastboot command I tried):

FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed

What could be causing that error?

I don't use this device ,but from experience with asus devices , u can flash with a service/fastboot firmware and bootloader will be locked back , but you've lost ota updates for good.

The original post to relock is a text file with the command "fastboot oem asus-back" which is what I tried (and have seen elsewhere on the internet for the Zenfone 7), but it gave the error in my first post.

I keep getting this error: "failed to unlock your device, please try again later".
Factory reset over and over, serial is in settings, brand new phone out of the box today. I added a google account after factory reset, nothing, I gave it Asus account after factory reset, same error.
What can I do? Should I do the firmware/software update?

For anyone reading this, wondering why there isn't a more descriptive error:
Unlocking your bootloader on this model goes against what a lot of us have learnt over the years. The general rule of thumb is never to update before unlocking, as the procedure for unlocking is specific to a certain release, and manufacturers frequently remove the ability to unlock in later releases.
Why they do this is obvious, they don't actually know what people will do with their hardware given the appropriate power to do so.
In the case of this phone, you do have to do the firmware update before the current unlock tool will work, as at the time of writing.
You don't need a Google or Asus account or any other crap.
Hope this helps someone else.

wheres tutorial to unbrick?

How bricked are you talking?

I answered a similar question in Q&A, the second post. That is if you can only boot into fastboot mode. but it also works if you are stuck in a bootloop or any other software issue.

If you can't even power the phone on, you will need to use a hair dryer or heat gun to remove the back and then disconnect the battery, then plug in a usb cable to see if the device still powers on. if it does unplug it and reconnect the battery. then try powering it on again.

If you unplug the battery and plug in a usb cable and it still does nothing, then it is completely bricked and probably beyond the technical expertise an average person is willing to put in to attempt to fix.
