Update from Asus
The service team reply misunderstood the situation. Unlock tool is unavailable at this moment but we are allowing the possibility to unlock, please stay tuned.
**TL;DR
- ASUS has apparently withdrawn the ability to unlock the bootloader on its phones.
- As per the company’s technical support team, Zenfone 10 and Zenfone 9 users won’t be able to root their phones.
Two things previously possible in stock android (via appops & adb backups), but no longer possible to any realistic extent (particularly ADB backups, as most devs disable this for their apps). These are the main factors for me rooting personally
