So, I bought a Zenfone 6 aka Asus 6z in May, unlocked bootloader, installed a few custom ROMs, and around mid June, it starts giving random reboots, including freezes, and I had to hold the power button for 20 seconds to restart... So I flashed stock ROM, relocked the bootloader, and gave it to the service centre. Got the phone back in a week, and now I'm unable to unlock the bootloader. Unlock App won't work saying it's a network issue. It's been a while, and I'm still having this issue...

The OEM unlock toggle isn't available though, even after enabling developer options. It seems like that toggle disappeared... Any way to get it back?

  1. Model Name: ZS630KL

If you need any more info, just lemme know.

Edit: Someone on Asus zenfone 6 dev group on telegram suggested tagging you guys... @Anders_ASUS @CH_ASUS

Hopefully you guys will be able to help me out. Thanks in advance...
