Hello,
Try going to the recovery, turn it off from there, then back on.
If it still doesn't work, factory reset, wipe everything, then turn off from there and turn it on again.
Again if it doesn't work, flash again the previous rom or the obe you want.

Put 5.3.3.3.zip on internal, after disconnect usb cable, you will see update notification. Follow it until finish.
Do it again with 5.2.2.2.zip with same proccess.
Afer this, system will became 44.
Update via OTA will make your device to 540. The last kitkat.

Red state message after trying to flash preloader to root (ZC520TL)

Hi boys, i've done some mess on my cellphone! I flashed a preloader to root without have unlocked bootloader, now my cellphone hangs on asus screen with the following message:
Red State
Your device has failed verification and may not work properly
Your device will boot in 5s
After that, it reboots and goes to the same screen. I've tried turning it off but it won't, nor it goes to recovery screen, it keeps on booting loop on that screen.
Its a zenfone 3 max, ZC520TL.

Good day good sir,
I know the following may not be of much help, but I'm afraid you will need to return it to Asus for repairs, because:
1. Bootloader is locked (that means no flashing)
2. You can't boot into recovery (no install via adb or micro sd)
I'm sorry I wasn't able to help much, but that's all I can say after experimenting with Asus's software for a while.
Greetings,
Kevin
Hi,
I have the same issue but instead of a bootloop, I can still boot android up with my zenfone max 3 zc520tl phone but I noticed that I can't turn on my Wifi. I this issue related to Red state? How can I fix the red state error? Please, I'm in dire need of help.
