Saving Data from locked, bricked device

Hey there,
as the title of the threat already indicates, my HTC One X got bricked.
As this usually happens when trying to flash some custom roms or recoverys, in my case it is the result of an official HTC update for android.
I can boot into Fastboot, and via cmd "fastboot devices" does show me the connected phone.
Now my approach for solving this matter was to flash the clockwork mod and then boot into recovery.
From there i wanted to pull data from the phone via adb commands.
The only problem is that my phone is locked. I cannot unlock it at the moment without wiping all data (which obviously would miss the whole data recovery point).
When i try tp flash the CWM in fastboot i get:
sending 'recovery' (8100 KB)...
FAILED (unknown status code)
finished. total time: 0.933s
I also tried to directly boot a recovery via fastboot boot recovery.img.
This resulted in
downloading 'boot.img'...
FAILED (unknown status code)
finished. total time: 0.933s
Well now I am seriously frustrated and dont know how to get my data.
Any help is very much appreciated.
Cheers
Josef

TWRP problem

Hi,
what i did so far was:
unlocked the bootloader
download the twrp recovery img (...ruu.lalleman.net/HTC_M8S%28QL_UL%29/Recovery/twrp-recovery-2.8.7.0-m8s-qlul/)
set phone on Fastboot USB
over the cmd bar (windows 10) i used fastboot and got this result:
C:\Android>fastboot flash recovery twrp-2.8.7.0-m8s-qlul.img
target reported max download size of 16510976 bytes
Invalid sparse file format at header magi
sending sparse 'recovery' 1/2 (15368 KB)...
OKAY [ 1.899s]
writing 'recovery' 1/2...
FAILED (remote: image error! (BootMagic check fail))
finished. total time: 1.907s
I have no idea what i did wrong or how i can solve the problem. I just wanted run the twrp, use the Superuser. zip to have the rootet htc one m8s.

Help, I need some tips to compile a kernel...

Hi! I trying to compile a kernel for our Lenovo Vibe K5+ and i'm having success on compilling, but, i have two output files in arm (Image and zImage) and just one in arm64 (Image)... I tried to flash via fastboot "fastboot flash boot Image" and zImage, but i always receive:
Code:
target reported max download size of 268435456 bytes
sending 'boot' (18616 KB)...
OKAY [ 0.749s]
writing 'boot'...
FAILED (remote: image is not a boot image)
finished. total time: 0.750s
The same in both cases... But, i tried to decompress an boot.img of CM13 for our device and recompile with my zImage but when i flash, i reboot and devices stucks in "Lenovo" boot screen...
Since now, thanks!

The bootloader is unlocked, and I have tried relocking and unlocking it to no effect.

As already noted, TWRP has never worked with 10. If you are on 9 then head over to the dedicated TWRP thread and get yourself up to speed.

if on android 9 it would be fastboot boot twrp. img. (if on Pie)
A/B slot devices don't have a dedicated recovery partition. (reason why flashing to recovery didn't work)
Android 10 doesn't have working TWRP yet. ( can't decrypt data or something)
