Upgrading Hboot help

Hello everyone, need some help upgrading hboot to try out some roms. Currently I'm on 0.85.2425 and when trying to flash from here (http://xdaforums.com/showpost.php?p=38947050&postcount=10) and here (http://xdaforums.com/showthread.php?t=2445593) I get a 'writing zip FAILED'. If I flash the rom.zip manually from adb in oem-78 mode [fastboot flash zip rom.zip] everything goes smoothly but hboot doesn't update.

This is what I'm looking at.

I'm pretty sure it is. I've always been able to issue commands without issues and flashing roms, updating radio etc.

The problem you can't flash in RUU mode could be the drivers or the fastboot app you are using.It could also be a CID problem.

You can check here how to upgrade your hboot by using fastboot.

But as long as you are S-OFFed you can flash a PD98IMG.zip from your bootloader by putting it in the root of your sdcard.(Just rename the rom.zip to PD98IMG.zip)

I don't know what a RUU mode is nor am I using any fastboot apps. I will look into this CID stuff.

I actually cannot do the PD98IMG.zip thing as my volume buttons left their home... and the visible metal contacts don't do anything if shorted.

Thanks for the link, I will check out!

EDIT: The post you linked me to has the same instructions as what I've been trying, I mean exactly the same stuff. This is the 3rd hboot rom.zip I've tried and it worked! I'm on 2.00.29 so thanks a bunch for that link
EDIT 2: Now unlocking the bootloader from HTCDev, got to last part and need to use volume buttons! Doh! I'm stuck now and the phone will not boot into the ROM.
EDIT 3: Got it! I didn't realize that there was a tiny button under the actual volume key, just had to press it with something small.
