My HTC one SV is stuck in bootloop and no Recovery-options help. Is it bricked?

A while ago my phone lost 90% off the contacts and a lot of apps just broke.
but the rest worked fine so i tried to restore everything. Last weekend it went into bootloop and everything i found on the internet would not work.

I got into bootloader, so here are some details:

the bootloader is Locked
K2_UL PVT SHIP S-ON RL
HBOOT-2.21.0000
RADIO-1.21.40f.00.23
OpenDSP-v13.2.0268.0620
OS-3.11.162.6
eMMC-boot 1024MB

I heard if you can access the bootloader the phone is not bricked, but none of those options change anything. is there a way to use the phone again?

Bootlooping is one of the definitions of a soft brick, so yes, it's bricked.

You can flash the stock ROM and you'll have an out-of-the-box phone, unless there's some hardware that's gone bad. See One SV Android Development - XDA Forums for help.

ok so i unlocked the bootloader and tired to put twrp on it but it stays on the htc screen. i did everything like the site said but no results.

thanks for the response. it helped me a lot
