[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...
http://forum.xda-developers.com/showthread.php?t=861259
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 keeps restarting

I'm new to this phone stuff and I tried downloading Valhalla v1.3 from http://forum.xda-developers.com/show....php?t=1203591 from recovery mode and my phone rebooted, and now it keeps restarting over and over. I have access to download and recovery mode only. I don't know any ROM or flash business so please help.

Okay so if you can get into recovery, then you should just flash any ROM from the development section of these forums.

You flashed a different phones rom. Which means the scripts and the radios and everything is off. Don't flash anything that doesn't have a T989 flashable thing oon it. You got lucly. Most people have a full brick. Be careful next time. And go to the Developers section. Download a stock 2.3.6 or Juggernaut v.4.1 and flash in this order
1. Place file on root of sdcard
2. Reboot recovery and wipe data/cache/dalvik cahce (found under advanced)
3. Flash the rom you desire
4. Reboot.
5. Let it sit for a good 10 minutes

Answered you in the other thread you posted as well ...
IF you can get to download mode, find the Stock ODIN flash for t989, and follow the directions, ODIN does not care how full your SD card is ...

Then just odin. Find a stock one that has an Odin Rom next to he title and flasheed that.
1. Go into download mode, turn off unplugged. Then hold volume up and down and then plug in usb chord.
2. Open up odin 1.85
3. Click the pda part and browse foot your rom.
4.click start and be patient don't touch anything

Is this the same thing as putting the ROM on the SDcard and doing it from there?

Yes and NO ...
the term flash or flashing means writing new files to the phone ...
ODIN is pretty much a Samsung factory tool, it will overwrite anything that is on the phone with what you are trying to flash ..
Flashing from CWM recovery is a "Softer" way of doing it, it may or may not wipe, it may or may not replace corrupt files, depending on where and what they are ...
IF you are having major trouble with your phone, and can still get into download mode ODIN is the cleaner way to flash it back to stock, but, read read read read till you understand what you are doing, then read it again ....

[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:
http://forum.xda-developers.com/showthread.php?t=1725839
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".
download mode/ Odin mode is working- I have downloaded the file:
Samsung-Updates.com-SGH-T999_TMB_1_20120523140229_ogindgck8z.zip
but haven't been able to get Odin to load it ... I have to be in download mode for that to work right?
Any tips are appreciated.

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!

Problem With Root

evening fellow rooters and droid users
i never ran into root problem before with any of my past previous phones but there is first for anything these days. so it be greatly appreciated if i can get any input from anyone about my problem.
i have tmobile galaxy s3
droid version 4.0.4
i followed the step of downloading odin3, cwm superuser and clockworkmod.tar.
copy cwm superuser zip file to my sd card
boot into download mode. ran odin3, click on PDA and locating the clockworkmod.tar
i've been reading mix instructions of UNCHECK and/or UNCHECK F Reset Timer. which one is correct?
press start everything passed and the phone automatically reboot.
powered off the phone and hold VOLUME UP and HOME and POWER button to try to get into CWM recovery tool. but i end up getting into android's recovery system NOT CWM.
where do I go from there? i re-install and used odin over 5 times already and no changes.
what should i do?

Read this it should take care of it. let me know how it goes.

i appreciate your reply however it didn't resolve anything.
the installation of the cwm.tar file supposedly say success and not failed.
i just can't seem to get into CWM recovery.
i am assume the installation of that cwm recovery.tar file didn't go thru?

Ok the other thing you can try is after you flash via odin remove the battery before it reboots when done flashing thru odin. Wait about 5 to 10 seconds put battery back in and hold volume up + home button + power button and when you see the little blue letters on the top left of the screen let go of all the buttons and it should take you into CWM. Then install superuser.zip. reboot and then you can flash recovery from either rom manager(cwm) or goomanager (twrp) and it will stick. Let me know what happens. I'll be checking the thread for your results. We will get you rooted!!!!

u beat me to the punch sir.
i was just going to say i found solution by removing battery after the installation pass.
problem solved. hopefully someone makes a note/sticky that anyone with version 4.0.4 on tmobile galaxy s3 should remove battery as instruction and take off auto-reboot.
thank you sir

Glad you got it bro, and welcome to the madness.

Its probably because after any ota update stock recovery will rewrite at boot.
Delete these
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
Reinstall cwm and youre good to go.
Ive got a fw thread stickied in development and will be adding this and more soon. Will try to start on it tonight.
Theres another way without battery pull btw. Check there later and ill explain it.

I didnt see that, but its the only reason Ive seen that recovery wont stick after a reboot. They only put those files in with otas as its how they patch/update the recovery. You shouldnt see them any any of the odin flashable firmware.

[Q] Black Screen - Won't Boot

Was using the Galaxy S3 toolkit to update cwm, went to flash an AOSP rom intended for d2att models, went to reboot the device... It flashes the samsung logo briefly then sits at a black screen with a solid amber LED. ODIN does not see it, my PC sees the device but I can't flash anything at all. Can't get to download mode either holding the power and any combination of the volume keys does nothing. Someone please help point me in the right direction to fix this. Thanks in advance.

If or PC sees it u could check and see if ADB sees it and maybe wipe and flash from there

If it takes longer than 10 or so minutes, pull the battery, replace and booting into stock recovery. Wipe data and cache. Reboot

It take bit longer than normal but it should boot within a minute or two
