Hi all interested in this device does anyone know if the bootloader can be unlocked?

Thanks in advance :good:
Also interested in this. Anyone?
The bootloader can't be unlock at the moment. Asus is known for giving the tools to unlock the bootloader. So its matter of time to have the tools to unlock it.

Source Code is on Asus website I don't get why it's not available yet?
Hey there I posted this under "rooted":

Hey, just went onto ASUS global & US website and saw that there is an unlock bootloader utility for the ZS550KL (updated 11-Nov-2016) but not one for the ZS570KL. Does this matter, since both phones are "Deluxe"? If not, any assistance to unlock bootloader and root the ZS570KL. Thanks!

Any help or feedback, greatly appreciated.

Fairly new to rooting phones and this question is due to my inexperience, but if the phones are both considered "Zenfone 3 Deluxe" what does the size have to do with it? Thanks for explaining.

well according to the this link here ... https://www.asus.com/Phone/ZenFone-3-Deluxe-ZS570KL/HelpDesk_Download/ (This is for 5.7 and there is no show of bootloader)

however this link here https://www.asus.com/Phone/ZenFone-3-Deluxe-ZS550KL/HelpDesk_Download/ (shows a bootloader unlock for the 5.5 version)

We need developers to jump on this darn phone and get it going somehow, if there is anyway possible to get their attention on it. I was able to tweak my phone a bit more with the startup manger (free) from google play to get more ram space.

5.5 has SD820 cpu, 5.7 has SD821... Would you try and use the other, untried method of unlocking if it may destroy your expensive little toy?

This is untrue. The 5.5 has the SD625, and the 64GB 5.7 has the SD820 and the 256GB 5.7" Special Edition has the SD821.

While it could be possible that a bootloader unlock tool for the SD820 could be used on the SD821 (but maybe not) because the architecture is essentially the same, an unlock tool for the SD625 most certainly would not be as it is a completely different processor.

I emailed Asus support and got this as a response:

Me: "When can the bootloader unlock utility be expected to be released?"

Them: "Unfortunately ASUS does not actually asssit with unlocking of the Android Bootloader. I must advise that you do so at your own risk, as once the boot loader is unloked it will void your warranty. But we will transfer customers' wishes to the related department for further development."

Edit: I prodded them further and received this in response:

"I have transferred your wish to our Product department, but temporary the accurate time the unlock tool for this Zenfone 3 Deluxe model would be released couldn't be ensured."

Which I believe means: 'We can't give an official release time yet.'

Hey, thanks for the explanation. I did not even consider looking at the specs (chipset) to see if there was a difference between the 2 models. I just thought they were the same phone just size of screen difference and/or less storage. Forgot they also release a 820 model.

At least you can get to the heart of the menu of the recovery, just can't do much there either. Thanks to a lucky source right here.... been trying find out how to do this...
https://www.asus.com/zentalk/thread-120913-1-1.html

1.) Turn off phone completely
2.) press power button and volume down at same time and hold it untill you see an android logo with an "!" with the android logo that says "no command". when you see the logo release all buttons.
3.) Now, press and hold power button first and then quickly press volume Up. You will then see the options including wipe cache.

Was it necessary to post the same in 2 threads?
Anyhow, check my original thread for rooting again. I included ZS550KL Nougat rooted boot images.
Test & share your feedback in the original rooting thread.
