Unauthorized bootlooping phone - Android Q&A, Help & Troubleshooting

I have received an acquaintance's phone for repair. It's a QMobile Z8 Plus (a.k.a. Wiko Ridge Fab 4G I think)
The phone is bootlooping on the logo screen. On trying to get into recovery, I get a screen showing "Encryption unsuccessful" and the only option provided is to "reset phone". Upon hitting the "rest phone" button it starts bootlooping again.
I have tried adb debugging trying to unlock bootloader or root or flash custom recovery etc but unfortunately I get a device unauthorized error. Since I can't boot into android to enable developer options and then connect the phone to PC and complete authorization, is there a way I can fix this thing by bypassing authorization or something similar?

Can you boot to Download Mode? Just flash the whole Factory Firmware using QFIL.
I have done that for QMobile Z8 but not for PLUS.

[Q] XOLO A500 hard bricked

I'd rooted my XOLO A500 device but i didnot flash CWM or CyanogenMod recovery after rooting. My phone got stuck in boot loop a.k.a soft-bricked. I flash stock ROM using Phenix flash tool but it hard bricked my phone in turn. Now my phone doesn't respond to anything-charger, data cable nothing. I re-flashed again & the flash tool on the PC shows "Backup QCN" but the phone doesn't reboots or recovers. My phone is not going to recovery mode either. What to do? Suggest me something.

Before flashing Xposed, You need to get full backup of your device in TWRP. After flashing If it unable to start, then restore only boot from your backup. And your device will be start.

I don't know if your problem is that when you boot your tablet and it stucks in logo and it says "Custom Binary blocked by FRP lock" <-This message appears because you haven't unlock the Oem in developer options. The solution will be downloading a system for your model and flashing it by Odin. Due your device no longer turn on.

[Paid Request] Homtom Zoji Z8 Stuck In bootloop

So I was rooting my Homtom Zoji Z8 phone by following this guide: unofficialtwrp .com/how-to-install-twrp-recovery-root-zoji-z8/
I was able to unlock, flashed the custom recovery.img file, and then my phone is stuck in a boot loop, says something like "your phone can't be trusted , Orange State" and then displays some random blurry colors on the screen, and reboots again.
I tried rebooting the phone via recovery, accessing it via adb , but nothing is working. Is this phone done for good or can I save it?
Happy to pay for anyone who can help me with this.
