Help with partially bricked EVO 3D Unlocked - S-ON

[mateo650]

Hello,

I have an EVO 3D that was having screen issues.

When I took it to the Sprint store they said my warranty was void for having ViperRom on the device.

The device was HTC unlocked and had ViperRom redline.

I asked them to not note that down and that I would come back tomorrow with the device back to stock settings.

I made a mistake though when I manually flashed a boot.img using adb.

Now I just get a blank screen when the phone starts. I am not able to enable USB debugging or disable fastboot.

Now I can get into the bootloader by using power and the down key.

Since the phone is in Unlocked Mode and S-ON I can't update through ADB without USB debugging or fastboot disabled.

Also any PG86IMG.zip on the SD card doesn't ask for an update when the phone is HTC unlocked

There is no bootloader option to relock the phone either.

If anyone can please help I would greatly appreciate it. I'm supposed to go back there today 9/18/2012 at 4PM PST

I can see when I turn the phone on it's actually functioning, just with a black screen. It still makes noises for receiving text and so on I just can't enable usb debugging and disable fastboot blind. I wonder if I found my HDMI adapter if an external display would work. That would be weird.

UPDATE: I figured it out that just by selecting fastboot and THEN connecting the USB I could get USB connectivity!

Run the stock ruu through fastboot
