Android I bricked my ASUS Zenfone 2 ZE500CL (Z00D), no bootloader, displays USB logo

[smileyhead]

I was trying to install Lineage onto it, but it kept erroring. A friend of mine said he could help, and he tried, but bricked it. He said he followed a guide, but left out steps, because he thought they were not important. Now I don't have a bootloader.

When I power on the device, it displays a USB logo with a white line under it for a split second, then powers off. If I connect a USB cable, it stays on for ~2 minutes before powering off again. No Windows or Linux computer detects it. Can I fix this somehow?

I saw unbrick guides on XDA for similar problems, but they were only for the 550 and 551 models.

Thanks in advance!

Wow. He offered to install it and skipped steps because he thought they weren't needed? God. Here, ladies and gentlemen, is the reason why people brick with Plailect's guide. Lulz


Anyway, without a bootloader, I'd say JTAG is your only option.

I had the USB logo with a white line underneat display several times on my original Zenfone 5. I wouldn't consider mine as a brick though as I got out of it easily. Try holding the power and volume up/down button or both of them.

Unplug battery, plug it via USB and see if it reports. If not then you would want to install custom-made drivers for it. [It should work, managed to unbrick my hard bricked phone which unmounted SDCard in TWRP Recovery after wiping OS ._.]
You can also force flash with some tools.
