I have a Trinity with LT2.0 (never touched backups) and a 640 GB Hitachi hard drive. Had no issues glitching with a Coolrunner running on the previous Dash. Didn't revert back to my original Nand before running the new dash 14699 update via usb. A window pops up indicating that the update would also run a number of security checks, was asked if I wanted to continue or not. I went ahead with the update and bam, black screen. My console was on, but no picture. Power cycled, the coolrunner tried to glitch a couple of times and then it would just quit.
To make a long story short, reprogrammed my coolrunner, erased my nand and reverted back to original. Was then even able to go back on XBL(albeit with a clean 320 gb hard drive, even loaded an old profile). Went back ECC glitched the Nand and loaded Xell no problem. So proceeded to write a hacked Nand, flashed fine. But for what ever reason, my console won't glitch. The coolrunner tries and tries to no avail....
Going back to my original Nand right now....
