Tried unbricking with Heimdall; Now even USB JIG cannot boot phone? What?

Hello! I'm encountering a very serious problem and any help would be extremely appreciated. I had Bonsai4All on my phone (Samsung Galaxy S / Epic from Sprint) for months with no problems, til one day it randomly stopped booting and would just loop the Samsung logo or get stuck at the battery with the circle icon. Using the Clockwork Recovery menu I tried to re-flash the firmware but with the same results.. and now the 3 button download mode feature didn't work.
SO.. I got a USB JIG. That got me into Download Mode. Using Heimdall, I followed this guide (Simple Step By Step for ODIN/HEIMDALL recovery "HOW TO UNBRICK YOUR FASCINATE" ) to reflash my firmware with "CI500_VZW_EB01_FROYO_REL.tar.md5" which I now think may not have been the right file for this phone. After it uploaded all the data and said it was successful, the phone turned off. I expected it to restart, but it didn't. Just a black screen. I had it plugged into my PC via USB still. No LED to indicate it's charging, but that had happened before and it still was. Tried the power button, nothing.. unplugged it, took out the battery, put it back in, tried the JIG. Nothing--- stays at a black screen. Power button and various button combos have yielded nothing.
Does anyone know what the heck happened to my phone, and if there is anything I can do about it? I'm at the end of my rope here. I've heard of JTAG recovery, but I imagine that involves buying new tools, tearing the phone apart, voiding the warranty entirely, doing dangerous precision SMD soldering, and even then it probably isn't going to work..
Is there something else to try or should I just look into selling this to someone who can fix it, or for parts, and get a cheaper phone?
Thanks.

Ok, so you can't hold down 1 and the power button together and get to download mode right?valso, I have heard of the jig but where did you get it?

I was advised to take out the battery for 20min and then try 1+Power, I will do that in 5 minutes. That is a combination I'd not heard yet. I got the JIG from a shop that sells through Amazon.

OK, tried 1+Power.. nothing

Ok, try what you just did: Take out battery for a few minutes. Also, take out SD card. After a few minutes, plug cable that's connected to PC into phone with battery and SD out and try holding 1 and power down together again to get into download mode

Well, possibly the battery somehow died during the process. Also, I believe he was pointing out that if the battery is getting warm then the phone may not be permabricked. Usually you can find a way to rescue it. Its too soon to give up on it

Yeah, if you need the right file, let us know. Hopefully you get your phone to wake up

Not to sound negative but I used Odin and flashed the wrong file once and my phone never recovered. I tried everything for countless days and eventually gave up. When i took it to my local sprint repair center they said they couldnt get it to turn on either. It sucks but it might be your best bet. just come up with a good story (of course leaving out that it was rooted) lol

Anyone want to buy this phone cheap? Physically, it's fine. I can't deal with this anymore.

Its trashed if you used the wrong file, because the pit that is auto detected in the Facsinate file will destroy info needed and it can't be recovered (the info) anyway that I know of.

If you do get it into download mode, I would try hooking into a computer with the battery out, then hold the 1 key on the keyboard then add pressing the power button together. You will want to grab the files from this thread and add the pit file and check repartition. Uncheck F.reset if in Odin. But Heimdall is better.

I once thought my epic failed and i tried holding the "1" and the power button on and putting the battery in and it worked.. i never tried it while plugged in though. Another thing i heard about was some reset button below the camera.. haha never tried it though.. and heres a random article i found.. hope it helps

If you flashed an epic with fascinate firmware you're pretty well hard bricked. The dude from mobile tech videos can jtag it.
http://www.mobiletechvideos.com/blog/tag/jtag/
He recovered my captivate when I got drunk and flashed the wrong bootloader. Or if you're just going to move on to a new phone, I'll give you $25 and bag of cheese for the bricked epic. If I get a bricked epic, I'm going to rip the cpu off and trace the pins so we can get the unbrickable mod working for us too.

Id buy it. What accesories do you have and how much would you want shipped? I'm thinking 50 bucks.

I followed this thread and thought posts explained why it is NOT insurance fraud. And if that person wanted to pay the $100 to put in a claim that is what the insurance is for. Is it any different than the genius that uses their phone as a hammer or the angry girlfriend that throws her phone? Fraud would be if you said you lost your phone just to have 2 phones. I would like a better explanation please.

I think this phone is a goner..

I have researched with no help what so ever. A buddy of mine got a Epic Touch 4G and accidentally flashed gti9100 rom on there.
I told him I will try to help him out.
The battery that is in the phone is gone. It flashes blue when it's plugged to a power source and you cannot start the phone to "download Mode" with the battery.
As soon as you insert that battery and plug in power source, the phone attempts to turn on and at the bottom you get " 3 icons "Phone, triangle, computer" and underneath the icons it says "Firmware Encountered" and the rest I cannot read.
I have a Epic Touch 4g myself and no stranger to flashing and roms.(currently running codname). I can use m y battery in the other phone and it will allow me to turn it on and get to download mode. Problem is, I cannot get USB connection.
Tried different cable, computer, front ports, back ports, downloaded the gti9100 drivers instead on a different computer and still no connection. Really I do not think there is a fix, but giving one my try in the forums.
thanks

Best bet send in the phone was a manufacturer warrenty every phone was one I think. And tell them it wont turn on and u charged it for along time and call samsung and say tht

One other possible thing that worked on old epics. Try taking the battery and external sd out for a day to let the internal ram clear. Then try going into dl mode with the phone plugged in but the battery removed.

This is not always true. When I first got my E4GT I flashed an international ROM too and it actually let me boot into it but it was really messed up everything was stuck in landscape mode and none of the capacitive keys would work. I could not connect to the PC while booted into the ROM but in download mode I was actually able to. I would give the idea of taking the battery and SD card out for a day a try. What can ya lose?

Think I bricked phone using Android kitchen

I restored my phone to stock then made a backup using CMW. I placed the CWM back up in the original_update folder of the android kitchen. Then went into the android kitchen and deodexed, rooted and intalled busy box. Then i built the rom, signed it, placed it on my SD, card booted into recovery, flashed SuperWipe then flashed the rom I made. It installed fine and booted up but i didn't have any signal. So i let it sit for about 5 minutes then Powered off my phone but it stayed at the Good Buy screen for like ten minutes so i pulled the battery, when i tried to boot it back up it wouldn't do any thing. I held the power button down and nothing happened. I tried plugging in a usb cable and my phone still would't do anything Its completely unresponsive
Any suggestions?

I sadly did the same thing. I'm still trying to figure out what I did wrong in the kitchen to brick my phone. Mine powered up as well but upon restart it bricked. But its sad to say but its bricked. I did a warranty exchange. If you connect the phone to the computer it will register as qhsusb_dload and not an Android phone. Best of luck.

Unfortunately I don't have a contract with T-Mobile so i can't do a warranty exchange. I ordered the USB Jig and i'm gunna see if that fixes it, if not I guess it's just a paper weight :\

I hate to be the bearer of bad news but if its registering as a ghsusb_dload device, a jig won't work.....how do I know you may ask? Cause I tried that as well before the exchange. Haha. Good news is you can pay someone to jtag your device. I think its like 50-100 but way better than 600 for a new phone. You should be able to find the link around the forums somewhere.

3. Hold down the 'HOME' + 'VOLUME DOWN' buttons and press the 'POWER' button for about 2 seconds until a WARNING! Screen appears. Press the 'VOLUME UP' button to enter Download Mode.

^^^^He cannot get to dl mode it is hard bricked.
And to the op-
Unlike some devices where this was a savior it is worthless to us. You are hard bricked. Go get some jtag as this mode won't help you
I tried for a few days to talk to this phone in that mode.Using everthing from odin to cdma workshop to qpst to emma. Nothing will do it trust me

It was a customer phone i dont brick phones.

All he have to do is call Samsung and they will replace it you have a year factory warranty as long as theres no physical damage. They send the phone fast.

I can vouch for that cause I've had to swap out my 1st. Maybe not due to that particular reason, but still, if it doesn't light up they gets frustrated and swap time.

I used to have an Epic 4G Touch and yesterday accidentally flashed a kernel for it on my S3. I was left with a beautiful pebble blue coffee table piece. I started to freak out because I couldn't power on or anything. Long story short, I purchased my phone less than 14 days ago so I took it back to the store. The technician took a look at it, couldn't power it on and they gave me a replacement phone, no questions asked!!

I promise if you hard bricked hell or even soft bricked you can get it exchanged from Samsung as long as it's been less than a year and no water damage or cracked screen .I really think they don't look into all the rooting stuff they just install new software in the phone and send it right back out to someone else which works for me.
If you go threw your carrier avoid it they ask to much question call Samsung and i sware they will send you a new or refurbished phone but a working one and that's all you can ask for and i didn't pay a dime the box they send you to send your phone is prepaid by them i just put my bricked phone in there then dropped it off to ups. I will say this two times i wasn't at home and ups left the damn phone in the box right on my door step than goodness no one stole it.

Agreed-
Try pulling the battery and waiting a few seconds, then try to reboot. I did something while installing a rom and the phone booted but just showed a black screen but I didn't realize it.

It does help to know exactly what it was you tried to flash.

What rom did you flash...be specific...and where did you find it from?
Do you have TMobile PHP? If you do then you can get a replacement S3 for $5 from TMobile customer care. That is probably the easist way to fix this issue.

Reboot into recovery mode and wipe cache, dalvik cache and do a factory reset in recovery.
Do NOT wipe/format system.
Then reboot the phone and it should work fine.

okay i have the same exact problem. i tried to flash darkyrom iii from androidgeeks.com or something like that, and, i also didn't see that it was for the i9300 only and it went through the little setup process from within cwm (like its own little installer) all steps went fine and everything. asked if i wanted to reboot, i touched "no" then the installer closed and brought me back to cwm and cwm decided to just reboot my phone on its own anways. now im waiting for it to boot, nothing. research, take the battery out along with the sim and sd for about 45 minutes. nothing. i plug it into the computer and nothing happens. i take out the battery and plug it into the computer, again to no prevail. so with the battery out and the phone plugged into the computer, i hold power, home and volume down and a red led comes on the phone and the computer makes the "attatched device" sound. but isnt recognized by kies or odin. will a jig help me out at all?
*edit* i got the rom from here; android.gs/update-galaxy-s3-darkyrom-android-4-1-2-jelly-bean/

okay i have the same exact problem. i tried to flash darkyrom iii from androidgeeks.com or something like that, and, i also didn't see that it was for the i9300 only and it went through the little setup process from within cwm (like its own little installer) all steps went fine and everything. asked if i wanted to reboot, i touched "no" then the installer closed and brought me back to cwm and cwm decided to just reboot my phone on its own anways. now im waiting for it to boot, nothing. research, take the battery out along with the sim and sd for about 45 minutes. nothing. i plug it into the computer and nothing happens. i take out the battery and plug it into the computer, again to no prevail. so with the battery out and the phone plugged into the computer, i hold power, home and volume down and a red led comes on the phone and the computer makes the "attatched device" sound. but isnt recognized by kies or odin. will a jig help me out at all?
*edit* i got the rom from here; android.gs/update-galaxy-s3-darkyrom-android-4-1-2-jelly-bean/

You are about about the 50th person in the past couple months who done the same thing, flashing a 9300 rom.
The only way to get the phone back into proper working condition is to send it off to be Jtag'ed.
There are some very good deals on Jtag if you go to eBay and search for "JTAG Galaxy S3".
Good Luck!

thank you

Nope, I never had a need to. But I have read here in XDA that people do get excellent service at a good price at eBay.

hmmm... i was leading into my next queston which would have been; is there any specific seller you may have read about or saw somewhere that i should go to? cause, for me, ebay is a little... "ehhhhh.." you know what i mean? plus on top of that im sending in my phone so i just want to make sure everything is from a trusted source.
