Guide-windows 8-ADB/fastboot solved!
This is a guide to help people fix fastboot not being recognized with the new windows 8 consumer preview, which happened to me and i found the easy fix. After installing the preview,
1 connect htc evo 3d, let phone connect and install its own drivers, then under device manager, find htc-update drivers- download and install adb drivers http://www.mediafire.com/download.php?2tunwdxr3q2q8ec
2. Next go into sdk manager and install all updates that are current, make sure you dont let computer go into idle and if files arent downloading correctly, simply redo the update till everything updates properly, might take a few times because windows 8 isnt optimized yet for file transfer, who knows, etc
3. FASTBOOT IS NO LONGER UNDER TOOLS, BECAUSE ITS UNDER PLATFORM TOOLS. the update puts fastboot from tools to platform tools, so to get adb/fastboot to recognize you have to shift/commandprompt where platform tools are for it to recognize adb/fastboot and let you issue commands
There you have it..... maybe i should go into developing, i just got lucky with this, i hope this helps one person out.... rocking the new htc one s rom, htc evo 3d until the next 3d, keep the developing coming
