I had the same problem but I locked the bootloader by accident while being on a rooted stock ROM. The reason that the ROM is not working is most likely because it's outdated. I was on 2.33.710.9 and I tried to flash roughly the same version. So unfortunately, I don't think a downgrade to nougat (version 7) will work. But, to fix your phone, download your version from here: https://www.hardreset.info/devices/htc/htc-u11/faq/firmware/. Once you have downloaded it, rename it to 2PZCIMG. Then, put it onto your SD card. Go to bootloader, and should say flash zip vol up for yes and vol down for cancel or something, and press volume up. Let me know if it works.

Thanks.

 

[Mr Hassan]

Let me know if it works.

Thanks.

1st of all thanks for your time bro, but as i said i already try to flash but its fail and the error is already mention, 1 rom is from this site which you suggest me, and the rom name is also mention which i try to flashed, maybe from this or another site,
Can you provide me the exact link of correct firmware it'll save my time,
And let me ask you one question htc is not possible to flash online? Like iPhone's?
