Hard brick resolved
I finally have everything working again. I had the phone booting via the "unbrick" SD card last night but every attempt with 2 different MJB zip files failed. I eventually just found this one http://www.androidfilehost.com/?fid=23212708291681451
and tried it and it worked. I can boot without the SD again. I did donate to him as a thanks.
First I followed this thread (and read through Mr x's thread as well) - http://forum.xda-developers.com/show....php?t=2549068
I was then able to boot the phone via the special SD card.
I then kept fighting with trying to get it to boot without the SD card. Since I could get to download mode I again ran CF-autoroot and I flashed TWRP 188.8.131.52 via ODIN. I kept booting to recovery and could not get either MJB bootloader that I found to work. I did get a status 6 when I tried CWM which indicated a syntax error or formatting error. I eventually found the zip file below and that worked via TWRP and then I was set.
I hope I remember everything - I was up until 4am and then didn't get a lot of sleep so I'm a little "fuzzy" now... :P
I will try to clean this up later for other's reference.
Edit 4: I can now get to TWRP by booting via an SD card with the unbrick file. I can also get into download mode. I tried flashing the MJB bootloader zip file via TWRP but it keeps failing. What is the next step to correct the bootloader problem if I had MJB and flashed the MJ2 bootloader (yes that was dumb...). How can I get the MJB bootloader files onto the EMMC again?
Help! I have flashed custom ROMs hundreds of times on my Captivate, Note, and Note2. My wife's S3 has been stock and had the OTA 4.3 update. After a few attempts, I did get root and TWRP 184.108.40.206 installed. I installed this ROM http://forum.xda-developers.com/show....php?t=2075639
- was able to update SU and restored user some apps via TB. The "about device" still showed "enforcing and she had the MJB bootloader. I rebooted to recovery and again ran the "Knox removal script" which I had run a few times already. This time I ran it and then flashed the MJ2 bootloader from the OP. I can't get it to turn on now. I pulled the battery - no luck. I plug it into my laptop and I hear the sound of windows recognizing the device but it doesn't show up. If I leave the battery out and plug into the PC, then the red LED flashes. If it was my device I would be bummed but being my wife's phone, I really am hoping someone can help...
Edit: I have been trying the 3 button recovery and download options with no luck.
During my captivate days, I used a "JIG" for getting into download mode but am concerned even that won't help if there is a bootloader mismatch or something like that.
Edit2: Even though I have a black screen, I tried using ODIN and connected the phone and it says "added"! I will now look for a full bootloader flash via ODIN
Edit3: It seems like if I have the battery removed, hold the vol. down and home and then plug in the cable, ODIN recognizes it so I have a ray of hope but am still a bit "panicked". I am looking for a full MJB firmware flash via ODIN
