Unfortunately It's not working because the bootloader locked. And I cant do anything in fastboot mode. The only working command is fastboot boot xy.img. With this command I can boot my phone.
EDL mode?
Perhaps using test point to force edl and flash the rom thought miflash.

boot loop

Hello Guys,
I have problem with my Zenphone5.
The phone restarts after the asus log. Recovery mode does not load. You can only work with the phone in fast mode using adb fastboot. Unfortunately, I have a locked bootloader and can't flash twrp recovery. Is there any way to unlock the bootloader so that it can be flashed?
Thanks a lot for help!

Stuck on bootloop, can't pass even after flashing

So, i got a second hand mi 5 last week. Seller told me that it had software issue and I thought I could fix it. Because it was really cheap.
The device was stuck on bootloop when I had it. But I was able to open mi recovery and fast boot menus. i tried many options to flash a stable stock rom. The most useful one was to flash via XiaomiTool v2. It says successfully flashed and reboots but stuck on bootloop every time. (Tried few times already).
the bootloader is locked and no mi accounts binded to the device. Computer detects the device successfully.
I tried adb commands as well, but since bootloader is locked i couldn't get any further to flash or wipe.
Any useful suggestions?
Can you still access to fastboot mode?
If so, you need fastboot oem unlock to unlock bootloader first, before anything else.

Use EDL mode to flash a clean firmware - you can find all you need on the forums here. You can also try and flash a clean boot img only first using QFIL and see if that resolves it depending on which ROM you're on.
