[Samsung Epic 4G Touch] vinscuzzy:
So just got this phone a couple of weeks ago. I feel like Im no stranger to rooting/flashing, but obviously Im no expert. Ive flashed custom roms on ppc6600, ppc6700, Treo 600w, HTC Diamond, Palm Pre(rooted it, no roms), Samsung Moment, Hero, Evo 4g, Evo 3d, Hp touchpad, and for a few weeks my Epic Touch4g. Ive never had a single problem until today. I must admit when I got this phone, for the first time I was actually scared to root it/flash roms. I read and re-read everything I could find, and finally took the plunge. I had great luck until I tried to flash the jellybean port.

I was originally on Agats rom tFF18_v0.1.0 which I flashed through ODIN. I tried a few other TW roms but ultimately kept Agats rom as my nandroid back up. Since it was a safe kernel/recovery I would always restore my nandroid to do any wipes or flashes. I thought this was being safe.

This morning I updated the kernel with AGAT_v0.3.0 with tREC_v0.2.1 7/19/12, which I flashed through agats recovery. Worked fine. I then wanted to try out CM9. So heres what I did:

I downloaded/flashed the newest nightly and Gapps and flashed them in Agats recovery which worked fine. I loved CM9 so I made a nandroid back up along with my other agat rom backup. I did notice that it was a different recovery but just assumed it was safe since it was a newer nightly. (Mistake?)

I kept CM9 for a few hours and saw that a JB port was available on androidcentral. Had flashed enough without issue, so I thought I try it out.

Heres where I screwed up.

I downloaded the JB port, JB gapps and it said to get chris41g's [Kernel][AOSP] Safe CWM6/TWRP which I did.

First I wiped data(full wipe), cache, and dalvik, then tried to flash the rom in CMW recovery that came with CM9. It gave me an error and aborted the flash.

Then I rebooted the phone back into CM9 because I thought maybe I had a bad download. I went back to the site reread the OP and noticed I was supposed to flash chris41g's recovery first, so I went back into recovery, flashed the Kernel, rebooted back into recovery and tried to flash JB. I didnt wipe anything, I just flashed it. It seemed to do its normal thing, but the progress bar never grew, it just sat there. I let it sit for like 10mins and the next thing I noticed, the screen was off. I picked up the phone, hit the power button.....nothing except the blue light I had read so much about.

I accept full responsibility for what I did. But to be honest, Im really confused what I did wrong. I was under the impression that most bricks happened when doing wipes? This happened when flashing the rom, which Im sure wipes before flashing, so maybe that where I had the problem? Im gonna go to sprint tomorrow and see if they can help, so hopefully Ill get a replacement, but I DONT want it to happen again. Sorry for the MAJORLY long post, but I wanted to be thorough with my explanation so I dont make the same mistake, and maybe someone else could learn from my screw up.

If possible, please be gentle, I already feel like a total idiot.......

EDIT: BTW, if I didnt make it clear, Im COMPLETELY aware this was my fault. I knew what I was getting into, and messed up somewhere by not FOLLOWING directions to a tee.
