While this process shouldn’t be too risky, bricks can happen. None of us will be accountable. If you are worried, don’t do it.
This is a pretty simple method, however, you will need to have a working adb and fastboot environment. This method will work on any operating system that supports adb and fastboot. You should understand how to use a terminal window in your O/S. If you don’t understand adb and fastboot, you probably don’t need S-off.
Lastly, the work herein should not be stolen, repackaged, one clicked, bat’d, etc. The binary contained in DNA-rescue.img is not GPL and may not be reused, integrated into other work, reposted, or redistributed without our permission. The kernel portion of DNA-rescue.img is derived from unmodified HTC source. That source code can be obtained from htcdev.
For this to work, you must be HTCdev unlocked and have superCID (custom recovery/root is optional), see the thread below for help and information regarding obtaining superCID, unlock, etc. If you have taken the OTA for the DNA (sw version 2.xx) without FIRST obtaining superCID, there is no superCID nor s-off method for you currently. Note this thread is provided for convenience only. Please look for support for superCID/unlock in it's proper thread, do NOT clutter this thread with support requests regarding obtaining superCID and/or unlock! If you try this process without superCID, it will not work, and you may have issues:
SuperCID for HTC Droid DNA:
Download modified boot.img:
Download signed firmware:
adb reboot bootloader
fastboot oem rebootRUU
fastboot flash zip PL8320000-DNA.zip
4) Immediately issue the following command:
fastboot boot DNA-rescue.img
adb reboot bootloader

Getting an error 99 instead of error 92 after step 3?
Perform a few FULL power-downs and boots. Also, others have reported clearing caches in recovery helps as well.
