[Q] Can't update bootloader, stuck on CM bootscreen

So I tried updating from a CM10 nightly to CM10.1 RC5 today. It went did not end well.
I extracted the boot.img from the zip and ran "fastboot flash boot boot.img", I then ran "fastboot erase cache". However, when I rebooted into hboot I noticed that it still said H-BOOT-1.12.0000, I then tried to just boot into standard CM again, which hangs on the boot animation.
I've tried a ton of other boot images since then, but none of them work. Did I just brick my phone?
This is the information displayed on the hboot screen:

Please help
the boot.img won't update the bootloader! only the firmware does....
I just wanted to say the same thing..you mixed boot.img and h-boot
boot.img is ROM-s specific kernel, H-boot is like "bios"
To upgrade h-boot you can:
1. Reverse your phone to full stock and do OTA update which automatically upgrade h-boot
2. Or flash manually firmware specific for you CID - you can find firmware collections here http://forum.xda-developers.com/showthread.php?t=1957376
Search on forum guide how to properly upgrade h-boot, but as i recall (http://forum.xda-developers.com/showthread.php?t=1953338&page=117) you need to relock bootloader, put phone in ruu mode, and flash firmware- more than one if necesary! BUT DO SEARCH PLEASE !!
And to boot to your old CM10 you need to flash boot.img from CM10 ROM zip file that you flashed before - not this one for CM10.1

[Q] m8 Stuck on splash after SuperSu

I got a new HTC One M8 today and I might have messed it up. It is currently stuck on the splash screen "HTC powered by Android" on bootup but I can hit power+volumeDown+voluemUp to get it to reboot and use power+volumeDown to go into hboot.
Current Hboot status:

What I've done:
1) Used the WeakSauce method to unlock bootloader / S-OFF

Boots OK
2) Flashed TWRP recovery v2.7.0.2
Boots OK
3) Flashed SuperSu
Boots OK
No root
4) Tried combination of flashing latest SuperSu v1.99r3, older SuperSu, sideloading vs. installing, and clearing cache
Boot Stuck!!
The logcat I did only had the single message:
"- exec '/system/bin/sh' failed: No such file or directory (2) -"
So...I might have erased the /system partition or something else horrendous. Would flashing a ROM fix this? I could just install CyanogenMod...
Any help would be appreciated!
EDIT: I see that blank "OS-" in the hboot menu...that's not good.
ADB push or adb sideload a custom ROM that works on Verizon edition

S-off while in the fastboot menu

Hi,
Is there a way to s-off a HTC one M8 device while in the fastboot usb.
I was trying to flash the device but ended up stacking at the logo. I decided to fastboot flash recovery and then fastboot boot. This resulted in a situation where if I reboot the phone, it displays the HTC logo and then goes back to the fastboot menu. I want to s-off so that I can flash everything because I tend to think I loaded a boot.img which is incompatible with the soft.
