[SOLVED] Can't Access Download Mode... :(

I'm trying to access the Download Mode for my Epic 4g but can't seem to do so. I've flashed my phone back to stock several times in the past so I know I'm following the correct procedure.
The problem started after flashing my phone to Eclair DI18 using Odin and using the one click root & recovery 2.55. I was constantly receiving 2.2 OTA update notices so I clicked install thinking that I could restore back to stock if something went wrong. I received an error message during the update but the phone was able to start into Eclair so I didn't think anything of it.
Well, I tried flashing my phone back to stock today for the purpose of updating the phone, but I couldn't get download mode to start. Thinking that I could restore the download mode using one of my old back up files from CW3, I tried the restore option but it was a no go.
Is there any way to restore my phone without using Odin? I'm still able to boot into recovery mode. If that's not possible, is there anyway to remove clockworkmod recovery so I can bring the phone into a Sprint store?
Thank you in advance!

Download mode is built into the phone. ROMs shouldn't kill it. Pull out the battery, plug the phone into the computer. Now hold the 1 key and then press and hold the power button. If it goes into download mode then you can put the battery back in.

Just tried it but I get stuck in a boot loop. It boots into samsung screen, reboots, samsung screen, reboots...
With the battery in and usb out, i'm able to boot into CW recovery...

If you are holding the 1 button first then holding power you shouldnt go to the Samsung boot screen.
If you are I dont know of any other way to get into download mode. Sorry.

I found this old thread, which looks promising, but the link to the stock DI18 file is dead...

Trying to search for the file on google but no luck so far.

Maybe your 1 key is broken.
Do you BONSAI?

if the 1 and power= no download mode then maybe keeny is right and ur 1 key is broken, maybe use the samsung update tool with eb13 in it?
Does that make it go in download mode automatically?

Look in the dev section for the re-rfs rom and install that.

This is the first rom that actually flashed! Once the rom is flashed, I reboot the phone and it goes back into CWM recovery... Gawwwd, this is so frustrating!

Ya, I think so. From what I can tell, re-rfs should have worked on either green or orange recovery.

I took out the battery for awhile, plugged in my usb, and tried accessing download mode and it WORKED! Awesome! Thanks, man! re-rfs was the way to go

SOLVED! Thanks everyone for all of your replies

I am also having similar problem.
On pressing power on botton or Volume Down+Cam+ power button.. NOTHING HAPPENS.
However I can boot into Download Mode (on battery only).
1) Computer do not recognize USB Drive. (tried uninstalling drivers > rebooting > reinstalling > rebotting ) still USB device not recognized. Even tried with different USB cable. And different ports.
2) However I managed it on my other computer. Where only 1 out of 4 USB port recognize my device.
3) Tried Odin to flash EC05 Stock... It hangs at some place or the other, and screen goes off or some times green (very rare).
4) Phone do not restart in Download mode without battery.
I tried to boot download mode without battery (plugged into computer).. but it wont.
Battery+USB = phone wont boot in download mode.
Phone boots to download mode only on Battery.
After that If i plug in the phone and remove the battery.. screen still stays on.

Help Please: Phone not booting up

Strange thing happened to my phone yesterday night. I was watching netflix for a while and after some time the screen just went blank. I am not able to restart the phone. It got struck in the kernel bootup(Darkside kernel, TDJ's darkside rom) and it was restarting again and again till i remove the battery.
I am able to get into recovery mode but not able to restore any of my backup's. It just went blank during restoring system. I tried installing the same ROM(Darkside Digitsl warfare v2.5.1) from my internal SD card but it just went blank after some time. I tried the juggernaut-5 . It didnt throw up any error but when i restart it its again displaying the darkside kernel and boot looping.
Any one can you please help me to get out of this mess. I need to travel on Monday so desperately need my phone fixed before that. Please help. I have not installed anything new over the last 1 month and didnt have any problems till now. Thank you
System Details:
ROM: Darkside Digitsl warfare v2.5.1
ClockworkMod Recovery v5.0.2.7

Try it again. The phone has to be in download mode before you plug it into the computer. And are you flashing it as PDA? People have reported it taking a couple tries.
Usually if you can get into download mode you can fix it. If you're stuck and your computer won't recognize your phone, try getting back into download mode. If you're sending it in for repair anyways, it's better to have a full brick so they can't see that you rooted.
Another option if you can't get into download mode, buy a USB Jig, they are usually less than $10 and they can sometimes get you back into download mode.

What screen are you talking about? The download screen?
If you're seriously wanting to give up trying, and want to brick it, try flashing a stock rom from a different phone via Odin.

So Am i good for an warranty exchange? or will samsung would be able to know i installed custom roms. In the ODIN mode it still shows custom binary mode as NO.
The strange thing is i didnt do anything on my phone for last 1 month. The only thing i could think off is, one of scheduled titanium backup ran at 3.00 AM when i was in netflix with the phone charging,and i got a msg that the backup failed. When i woke up it started boot looping. And during the ODIN i tried today, I was making sure i am doing right by following the guidelines(ODIN back to stock).
I have all my nandroid backups(different rom versions) & titanium backups, will i be able to use it in my new phone after rooting with the same recovery version?
Thank you. I really appreciat all your help.

Are you running Odin as administrator?
Manually download the device drivers from the how to root thread and install them on your computer. right click on Odin and run as administrator. Open the stock rom file in the PDA field and run it.. There is no reason it shouldn't work if you can get into download mode.
Try downloading the stock rom again, maybe it's a bad download.

Locked Bootloader

Hey i believe i have somehow locked my boot loader. I can flash the rom in the recovery mode but it does not show up after booting the device. Its stuck on juggernaut 5.0 which i was recently using. I factory reset my phone dozens of time but no luck. Tried every damn thing in the odin even took a developers help but no luck. Even he was shocked. The system seems to be frozen on juggernaut. Is there a way around this. I believe i cant even brick my phone since even odin doesn't flash anything

You already posted this.

Really serious this time. So you cant get into download mode and have your phone recognized by odin to flash stock rom???. If you can get into download mode abd odin sees the phone, you should be able to put the stock rom in pda hit run and it should work. Have you tried using heimdall instead of odi ?

I can get into the download mode and can flash it through odin as well but once the flash is successful and when it autoboots after the stock is flashed it goes back into juggernaut rom rather than going into stock rom. I dont seem to get hold of anything. I deleted all my files manually like pictures and notes and stuff but once i rebooted the phone they were all back again. One of the developers even helped me step by step but that didnt even work he was rather shocked. He told me that your boot loader might be locked and he said i am not even sure you will be able to brick the phone!!!

sell it buy a new phone lol

What are you flashing? Stock ROM?

[Q] Can't get Galaxy S3 (Tmobile) to boot

So after rooting my recent Tmobile GS3 and then attempting to flash the overclock my phone simply wont turn on. The root did fine, and I was able to install setcpu and everything but the second I installed the overclock my phone shut down. Now whenever I attempt to turn my phone it just flashes the Samsung insignia and then it shuts down. I can get to the Downloading screen (by pressing Volume down + power + home) but can I do anything about that? If someone can help me out that would be amazing. Thanks.
Also, I tried flashing a stock rom with Odin and it keeps failing. If anyone knows anything thank you.

Can you get into recovery? Volume up + home + power
If so then flash back to a nandroid backup or to a new rom or whatever.
If recovery wont boot, try again but look for blue text at the top right corner that says "booting recovery" when the sammy logo comes up. I've had it where my recovery wouldnt boot but I saw that for a split second when I tried. If this is the case, get back into download mode and flash the insecure boot + cwm again with Odin. Then you should be able to get into recovery.
If Odin fails to flash, reboot you're computer and try a different USB cable.

If you can get to download mode, then you're probably in good shape.
There are a few tricks that can be found in this thread:

Just make sure when you odin/flash something, you are flashing the correct image for your phone/carrier.

same boat here
well I thought I'd give it a try using instructions here. and now I'm hosed. I was able to root and install the ALLINONE (Insecure Boot, CWM & Busybox) rebooted, super user showed up in apps etc. I thought everything was fine. the next thing I tried was disable boot up animation and now the phone won't boot up at all.
I can get into the recovery and download screens but whenever I try to restore I get "can't mount /sdcard/"
The toolkit no longer sees my phone either. When it's plugged in and the toolkit is active, it just cycles over and over "samsung" then "Samsung Galaxy SIII" logo then black screen repeat.
The toolkit keeps giving message either "device not found" or "Waiting for USB debugging to be enabled".

Try flashing the same file you did to get root with Odin... then you should at least be able to get in to recovery and from there you're golden.

I tried that a few times to no avail and gave up. figured out that I needed to unzip the stock rom from t-mobile in order for Odin to recognize and load it. That's where I left it last night. So I'm now back to stock and reloading all my apps and settings.
I'm ok with that, this is my first go at flashing/rooting. My phone works ... and for that I'm breathing a little easier. thanks for your reply!

Stuck in recovery flashing stock JB

I just ran the Samsung "simpleupgradetool" and there was an error when doing this. My phone is now stuck on the screen "firmware upgrade encountered an issue. Please select recovery mode in Kies and try again.
Sounds great, every time I use the emergency recovery in Kies I receive another error stating that the recovery failed, and if it continues to occur try Samsung Support.
Is there anything you guys can do to help me? More info needed?

Read the link on how to use the One Click if you're unaware.
I'm suggesting the no data so you have the chance to save your data.
Please come back and post if you were successful or not.
Also, Questions go in the Q&A Section.. Not in General. For future reference.

I am very new to this phone and odin..
Reading that I don't see how I can flash that from the recovery screen that my phone is stuck at. Please pardon my ignorance if i'm just overlooking something here.
