I finally successfully recovered my BootLooped Incredible after i incorrectly updated the NV item of my phone. My situation was a little different than most bootloop error because no matter which stock rom or recovery image I flash nothing would stop it from rebooting because the NV items weren't overwritten during the flash. Then I came across a solution for the EVO by cutthroatamft on how he recovered his EVO from the same Mistake but unfortunately all his files were geared toward the EVO. After much searching I accidentally came across a single comment that posted a link for the ENG-HBOOT for the incredible. Now i manage to replace all the EVO specific files with the Dinc equivalent. Below is the link to the files and instructions compile by cutthroatamft but I updated it for the Dinc. Hopefully this helps someone else that has this problem. can't post a live link but I think you can figure it out
Since megaupload is down and Had some people asking for a re-up here's a mediafire link to the file
Also as mentioned below by eljean this should work on the SLCD as well it's just your screen will be blank during the process. For those who has this Dinc I found that if the screen is blank wait a few minutes for it to fully boot then test to see if you can execute any ADB command. If you can the just type "adb reboot oem-78" this will reboot it and put it in fastboot mode which will allow you to execute the commands in the document.
Nevermind what I said about the ADB... this worked for me on another phone but I realize you'll probably won't get to a point where you can execute the command because your phone in a loop LOL. So I guess getting to fastboot blind folded is your only option
