I used it for a bit cause it was put on my phone when I flashed a 2.1 rom a few months ago. I wanst aware it was so dangerous. Flashed multiple roms with it, made nands, used it to upgrade SU... all was well for a few months, then while trying to flash a custom rom I started to realize it was causing my phone problems. I even flashed to an alt recovery (amons) using rom manager. That was the problem tho. I had amons but clockwork was still controlling everything and my phone (which had been running flawlessly for months) started to act up real bad. So I did alot of reading here on xda and learned clockwork can be mucho dangerous with the Eris. I went to the Eris Dev subforum and found a post on how to safely flash back to amons from clockwork. Did it, wiped the phone, put on a new froyo rom, and presto, no more issues. It may work fine for a little bit, even a few months, but silently in the background it screws with your Eris' brains lol. Glad I fixed that!
