Not long ago, we wrote about how XDA Recognized Developers beaups and Fuses had achieved S-Off on the Verizon HTC One using their recently developed Rumrunner S-Off. This was much needed for the device, as the Revone S-Off that worked on other devices didn't work on the Verizon part. Adding insult to injury, Verizon quickly closed off the previously working HTC Dev unlock for the device.

Thankfully beaups and Fuses were able to give back device freedom to Verizon HTC One users. Unfortunately, though, there was still another group in need of a new bootloader exploit. These were the people with the newer 1.54.0000 Hboot.

Since both Revone and Rumrunner for the Verizon model failed to work for 1.54.0000 users, things looked bleak. Luckily, beaups and Fuses were able to show their collective might and adapt Rumrunner for use with various HTC One models, including those that were previously unexploitable.

It is important to note that for this to work, you must be HTC Dev unlocked, you must have working drivers, and you must be running the correct mainver and firmware version. And since this is a potentially dangerous operation, you are advised to read everything many times, and follow every instruction to the letter.

You can learn more by visiting the original thread as well as the official Rumrunner website. Great work, as usual, by these talented developers!
