[Q] My Flyer is softbricked! - HTC Flyer, EVO View 4G

After doing a OTA upgrade from GB to HC my Flyer ended up with an error. It was s-off before this and working fine. I can not run ADB commands, boot up, run revolution, install from sd card, run recovery, htc unlock or fastboot commands. It only boots into fastboot and installing an RUU also ends in an error. Some fastboot commands is working but whatever I do I get Signature error, Bootloader error or FAILED (remote: signature verify fail). My getvar looks like this:
C:\Data\Android\Adb>fastboot getvar all

Can someone please give me a hand?

run the hc soff ruu posted in development by globatron. should do the trick .

---

Already tried that. It starts with: Run revolutionary and I cannot do that. I am at S-ON now. If I try to just run the RUU it fails!
Other things I can try?

if you were s off prior to attempting to upgrade you should not have been able to change the hboot version via standard update and you would be left with a gb s off hboot and a hc system. looking back at your post it appears you have a s on hc hboot but a system that wont boot. When you try to run the globatron soff ruu it would fail becasue you are s on. I am guesing since your system has been updated to hc when you attempt to run your stock ruu you are failing because the misc version is older in the ruu you are attempting.
I am kinda guesing here as to my understanding if you were s off prior you should still be s off, but maybe try to htc dev unlock. then flash recovery to your device. once recovery is installed you should be able to change you misc version following steps listed in globatrons downgrade from hc leak thread. After you change the misc version you would need to relock your hboot then attempt the stock ruu again.

try extracting the zip from the ruu and run these commands:
fastboot oem lock
fastboot erase cache
fastboot rebootruu
fastboot flash zip (filename)

---

Run the Honeycomb RUU, then proceed with the downgrade instructions.

---

I have tried all that and none of it is working. Some of it runs, but ends with an error like Signature error, Bootloader error or FAILED (remote: signature verify fail). I guess I'm stuck with a brick?
