Hey guys, I just upgraded from my good old galaxy s3 to the htc one m8 (ATT), pretty stoked.

I was having issues with unlocking my bootloader. I installed the Android SDK properly, but no matter what I did, I could never get fastboot to work. I always got an error message saying "adbwinapi.dll is missing". I searched online and came across these two threads:

http://forum.xda-developers.com/showthread.php?t=781386
http://androidforums.com/threads/adb...-error.609867/

which unfortunately didn't have the right solutions

What finally worked for me was copying adb.exe, adbWinApi.dll , and Fastboot.exe to the folder I downloaded from htcdev "fastboot-win". I then ran cmd prompt from that folder (shift + right click) and entered the command "fastboot oem get_identifier_token" which finally worked.

TLDR: copy adb.exe, adbwinapi.dll and fastboot.exe from SDK install folder to the folder you downloaded from htc dev unlock.

hopefully this will be useful for someone stuck with my same issue.

This totally worked when I encountered this. No sure why the files needed to be moved over but voila. Nice tip.

You should install HTCSync before trying to connect this device to a PC. HTCSync install includes all the necessary files for adb/fastboot, and should remove the missing DLL error.

If your issue is directly relevant to the thread subject, feel free to post it here. Otherwise, find a relevant thread, or create a new one.

For that matter, all "help" threads (including this one, actually) should be posted in the Q&A section, not here in "General": https://forum.xda-developers.com/htc-one-m8/help

Also, I would make the constructive suggestion: Please don't post to this forum like it's a twitter feed or SMS. Take a few minutes to compose your forum post, and think about what you are trying to say or ask, before hitting the post/reply button. Posting a few words or a single sentence every 5 minutes is confusing and clutters up the forum.

For example, if you ask for help, post as much information as possible about your device (carrier, region version, OS version), the events that led up to the issue, step-by-step description of what you have done or tried to fix the problem, specific file names of anything you installed, etc. A lot of folks will ask for help by just posting a sentence or two, which is simply the wrong way to go about it. Just forces us to request all the basic information they should have provided to begin with.
