Help! Can't boot into download mode. - Galaxy S III Q&A, Help & Troubleshooting

So I've finally decided to root my S3 and run CM9, as from what I hear it's very stable now. Only problem is, I seem to have fallen at the first hurdle!
I've been following the SGS3 full update guide on the cyanogenmod wiki.
I powered off the handset, booted into download mode, opened zadig.exe in the drivers folder of the heimdall suite, selected options>list all devices, selected "Gadget Serial", clicked "Replace Driver". A message popped up saying it was successful. The guide simply says to power off the device and reboot into download mode again. However, after this I could not power off the device. The power button wasn't working and I got no response from pressing any of the buttons on the device. Eventually I decided to open it up and remove the battery and then try to boot into download mode again.
Now, it doesn't boot into download mode at all. Every time I hold the volume down and home buttons, I then connect the micro USB and nothing happens at all - it just begins charging. The phone can boot normally and appears to be functional apart from this, but this is stopping me from being able to root. Anyone know what could be the problem?
Thanks!!

Just tried factory reset and still no dice.
Has anyone come up against this before?

And, just to be sure, you are holding down the power button when you press volume down & home on a powered off GS III, right? Since you say you're rooted, you can boot into download mode from the phone itself:

Run su reboot download

Yup, I was. Seems that after enabling USB debugging after factory reset, the problem has resolved itself. Thanks for your help anyway

No sir, you should be just fine, try to reflash back to stock using odin, pull the battery remove the sim and sd card, and then go into downloader mode, and try again.
stock FW here, good luck.

thanks in advance
Let me know if these steps help:
Here is a couple of methods to get into download mode. Once you get to
download mode, follow the directions in second part of my post...
First Method
1) Pull the battery, sim card, and sd card.
2) Reinsert battery but do not press any buttons.
3) Plug into usb that is connected to your computer. If something shows up
on the screen (charging logo) then you should be golden.
4) Hold the vol up, vol down, and power until the screen comes on,
immediately release the power button but not the other two. Hopefully it
will boot into download mode and than you can use Odin to get back to stock.
Second Method
1) Another method that seems to work for some people is to pull the battery,
sim, sd card.
2) Reinsert battery and hold both volume buttons but do not press power
button.
3) Then plug in usb. The phone should boot into download.
Third Method
1) You will need the samsung ADB drivers installed for your phone and ADB.
Samsung Drivers for 32 bit Windows: http://files.androidspin.com/downlo...=SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe
Samsung Drivers for 64 bit Windows: http://files.androidspin.com/downlo...ung/vibrant/&file=usb_drivers_GalaxyS_x64.zip
2) Remove sim card and sd-card. Remove the battery.
3) Hold buttons vol up, vol down, and power.
4) While holding down those 3 buttons put the battery back in and keep
holding all 3 buttons until the vibrant disappears and reappears. Once it
reappears, release all 3 buttons.
5) Now connect your phone to your pc via USB cable.
6) Open a cmd prompt and navigate to the folder with ADB and type "ADB
REBOOT DOWNLOAD" caps are not necessary.
7) Your phone will reboot into the download
How to get back to stock once in Download Mode:
Download the files in the linked thread and follow the directions there or
the ones in my post below.
Odin and Files Needed Available Here: http://forum.xda-developers.com/showthread.php?t=734475
1) Open Odin and verify that one of the Com ports shows a device connected.
If it doesn't try using a different usb port.
2) Load the .pit and pda files. It should be pretty obvious how to do that
once you are in Odin.
3) Make sure that the option to partition is unchecked. The other two
options should be checked.
4) Hit start and wait.
5) Your phone will restart when Odin is done and you will be good to go.
Seems to be the same issue
I just tried upgrading to 2.2 using Odin and this seems to be the same problem. It seems that every solution starts with, "Enter Into Download Mode..." but no method seems to work.
I wouldn't say the phone is "bricked" as when it is plugged into a computer it will install the drivers and Odin sees it, but I can't get it into anything but recovery mode.
The buttons seem to be strangely mapped, the up and down buttons are reversed and the power button doesn't seem to be working as the "Ok" button. The menu toggles the recovery screen and the <!> graphic with the Android. Anyone figured out how to solve this? In the meantime I will continue attempting to get into download moad.
Hi, I have the same exact problem. Stuck in system recovery. Volume buttons reversed. Power button does nothing. Cannot get into download mode. Please Help
what happened?
I just got the same issue :S
the volumes buttons are wrong and the power (OK) button is not working on system recovery mode...
any help?

Folks, any update regarding this problem. I got very same problem, and could not find a solution yet.
hints?
I have the same problem also. I got into the problem by following a thread down grading to 2e version from 3e version. I've tried lots of things including going back to stock--or what I think is stock. I now have the 3e version again but when I bring up recovery mode the up/down buttons are backwards and the ok (power) key doesn't work.
Suggestions? HELP?
We can get into root console and manually tweak files if that will help.
UPDATE----SOLUTION
I got this working by reloading the stock t-mobile kernel from http androidspin.com/2010/08/09/how-to-restore-or-recover-your-samsung-vibrant/. This link provided at that site is single file so just use the pda and pit boxes in odin. In desperation I selected re-partion and Phone bootloader update.
I was unable to get into the recovery console with hitting any keys but adb did the trick. Volumn-up and power gets into the flash download
Finally Fixed it
I finally was able to get the phone into download mode by holding down the volume up key, the search key and the power key.
It seems the key mapping was just messed up.
After it entered download mode I followed the guide on androidspin /2010/08/09/ how-to-restore-or-recover-your-samsung-vibrant (add the .com to androidspin, forum won't let me post links yet)
Hi How did you hold the search key. It does not light up till the vibrant shows on screen. Can you please explain how to managed to hold vol up, power and search together? thanks
Sivaavis its only a 3-button combo, not 4. Why u holding down search? Its up,down volume and power and then when the vibrant logo shows u let go of power.

If you are in recovery mode just go into adb and type in:
adb reboot download
You should be in download mode

[Q] Bricked my phone... another one bites the dust

YUP. I "soft bricked" my t-mobile galaxy s (vibrant here in the us) or so I hope. The phone was rooted via z4 on the latest android t959uvji6 from t-mobile.
How did i do it? Brick my phone that is...
The 3d gallery was pissing me off by picking up everything on the phone. I tried clearing the default setting via the manage app but nothing changed so I decided to delete it. First backing up the apk and odex file from the system folder with titanium backup then deleted them from the system folder via root explorer. Rebooted the phone, pulled out the battery, waited for 30 seconds or so, popped in the battery and booted up the phone w/o any issues.
I tried installing the backup 3d gallery apk file and got the "app not installed" error on numerous attempts. Then tried simply copying it over again with ti backup and nothing happens. Gave up and said the heck with and went the factory restore route, got all the relevant apps installed and tried reinstalling the 3d gallery apk but resulting in the same "app not installed" error prompt. So I again copied over the apk and odex file into the system folder. Rebooted and nothing... phone does not boot into the home screen.
At this point here is what the phone is able to do.
It will boot up and display the default galaxy s animation, goes through it's array of colors then comes to a stop at all white letters then the screen goes blank and nothing happens - zip. nadda. i left it on for 12hrs like that - blank screen w/all the hard keys lit up.
What i did notice was win7x64 recognizes the phone after it gets into the blank screen of death as mass storage units.
So far i've tried booting into the recovery screen via the three button method and none of them works.
Did the karma-volume up-home-power twist - nothing
Did the karma-volume down-home-power roll - nothing
Did the karma-volume up and down-power jiggy - nothing
I tried the key combos for about 2hrs without any success then jumped into adb. After reading for a bit I realized that the phone was still rooted and the debug mode was enabled the last time i shutdown the phone (good'ol ti-backup)
For a while there adb did not recognize the phone at all but with an odd power cycling while spamming "adb reboot recovery" it was able to finally nab hold of the phone and jump into the recovery console. At first I thought it was pure luck so unplugged everything and tried it again - works every time if i did the odd out of sequence power cycle while spamming the adb console with "adb reboot recovery".
In the reboot recovery - deleted the user data and did the restore.
Here's where I think I really screwed up - now the phone is no longer in debug mode.
Long story short - is there a way to get into the recovery screen w/o debug mode on?
**quickly pulls on flack jacket**
but seriously any suggestions would be great
Wrong section bro. You probably won't get an answer here.
To answer your question. Yes, Remove Battery, Plug your phone to USB, Press and hold the volume down and the power button Put the batter back on. This should get you into download mode. Use ODIN to restore.
the usb jig trick did the work - now i have two phones!!!! (bought the nexus s yesterday) lol
Time to ODIN.
To access Download mode.
Unplug. press volume up and down togheter, and connect USB. VOILA!
If ODIN does not recognize it, plug and unplug again

Why the hell are people giving others ideas on how to get into download when their doing it wrong.
its JUST THE VOLUME BUTTONS, NOT THE POWER BUTTON ALONG WITH IT.
volume + power = Recovery, which in this case you probably cant get into
Volume - Power = Download mode, which everyone can get into unless if they somehow hard bricked, if its possible.

Bricked after installing CM custom rom.

Hi, I just bricked my phone while installing the CyanogenMod stable release. Chances are that the zip file i downloaded was corrupted (The filesize was much smaller, must be an internet disconnection that i did not realise) and I am unable to boot into neither download mod nor recovery mode. When holding the volume up and power button, I see the load screen with the yellow triangle (obviously), and it turns black, and the same screen appears again, except that this time, it stays that way.
I tried to see if Odin can detect the phone but because it is not in download mode, it could not detect anything even when kies was switched off. (checked task manager to make sure i killed it) However, the computer was clearly able to detect the phone. (I am using vm ware and when i connect the usb to the phone, i am prompted to choose between connecting it to windows or mac) I then tried to do it in pure windows but odin was still unable to detect the phone. I tried Heimdall to no avail as well. My jigg should arrive in 2 days but from what i seen from the [debunk] Jigg thread, I am not confident that it'll bring me into the download screen.
Is there anything that can be done without sending it for repair? Thank you
Get your battery out the phone, put it back in and hold Volume-down + Home + Powerbutton immediatly pressed, You may have to repeat this several times. When its needed to repeat it more then once let the battery every try some more time out you device.
When You get into downloadMode flash an OdinRom
Hope it will help.
Alright! Thankfully, that worked after a few tries. Tried to flash CM7 again but apparently, it does not work. Think i'll have to ask people in the relevant thread. Thanks again!

help please!! i777 won't start and I run out of ideas

I have a rooted i777 with SHOstock rom, I haven't updated the rom for a few months so I'm not sure which version it is.
The phone was working yesterday and it suddenly got stuck so I tried to reboot it (had to take out the battery because the power button didn't respond) but now each time I try to turn it on it is stuck on a black screen with the logo "Samsung Galaxy SII" and won't progress.
I tried to boot to recovery but it shows a screen saying "CWM-based Recovery v6.0.2.7" but it doesn't go pass the screen to show the recovery menu (it just reboots after being stuck on this screen for about a minute).
I tried to boot to download mode and succeeded, but every time I connect the device to my pc, the pc doesn't recognize it
(I tried re-installing kies, but it didn't help and probably the problem is not with the pc drivers because if I connect my wife's unrooted i777 to the pc it does recognize it).
so now I don't have clue what else to try.
any advice will be appreciated.
Make sure you have Odin v1.85 on your Windows PC. Look in the Windows Add/Remove programs dialog (or Uninstall a Program dialog) to see if you have SAMSUNG USB driver for mobile phones.
Open Odin on the desktop. Next put the phone into download mode by holding down vol + and vol - while plugging in the USB cable.
If Odin recognizes your phone, flash back to stock. I would recommend UCMD8 stock firmware, which you can get from the Download Repository.
don't know what happened to it but now it doesn't even turn on.
it's stopped turning on before I had a chance to try what you suggested.
now even if I connect it to the charger it doesn't show the charging status.
is there any other "force something" I can try?

Remove the battery and leave it out. Connect the USB cable to your PC. While holding down the vol- button (also try it with both vol- and vol+) but not the power button, plug the USB cable into the phone. The computer will provide the power. If this works, your phone will go into download mode. If not... you have very likely had some kind of hardware failure.
unfortunately it didn't work.
can't get it to download mode.
I'll try to leave the battery out for a longer time and try again.
should I try ordering a JTAG usb and see if it puts it in download mode or
probably my only option is to send it to mobiletechvideos?
I had the same problem, Your battery got too low. Pull your battery and leave it out for a while 15 mins or so. Put the battery back in and connect charger. Let the battery charge for a while without trying to turn on phone. The phone will not turn on with a dead battery even if it is connected to charger.
I just solved a problem that I didn't find any help with, so I thought I would post it here in case somebody else needs help out of this situation, and this is a recent and related thread.
After I pulled the battery of my i777 to test in another phone, without remembering to power my phone off first, it would only hang at the Samsung boot logo (stock UCMD8 ROM, rooted, stock recovery). Normally the Samsung boot screen shows for only about five seconds. Pulling the battery wouldn't get it to boot right. Holding Power to force a reboot didn't solve it. After clearing the cache it would move to the AT&T Rethink Possible screen once, then reboot and then again get hung on the Samsung logo screen. Also my battery was heating up a lot as it was hung.
I could get into both download mode and recovery. I tried reflashing my ROM from the stock file in ODIN since that would save all of my data IF it worked. This still didn't get it to boot past the first logo. Finally doing a factory reset on stock recovery is what solved my problem. I had to re-add my account and reload apps from scratch, etc.

[Q] Phone is not being seen by computer when plugged in, usual solutions do not work

Hello all, thanks for helping me out.
I did a very foolish thing. I rooted my phone and deleted a few bloatware apps that were apparently very important to the phone's functionality. I did not install any recovery software like CWM, fastboot, or anything. It was a stock phone that I simply rooted to remove a few apps. When I went to restart my phone, I found out that I bricked it. Now my phone will only enter Download Mode if I hold the up+down volume buttons and plug it in, or it will get stuck on the LG logo screen and a Security Error screen. A factory reset with the volume down + power will work, but does nothing to fix it.
My immediate issue is that when I plug my phone into the computer, the phone will recognize it has been plugged into a power source (it will either go into Download Mode if I was hitting the volume up+volume down buttons, or start trying to boot up but cycle through the LG logo screen and Security Error screen) but the computer will not acknowledge that anything has been plugged in. There is nothing new listed in the Device Manager. I have read other threads and searched around on the internet. The usual solutions are not working for me:
I have tried several other cables and computers to no avail. I have also tested my current computer/cable, and it worked for data transfer with another phone (Nexus 4)
I have tried cleaning out the contacts on the phone. They were not significantly dirty.
I have tried installing the drivers from LG and even the UniversalNakedDriver
I believe that if I could get my computer to see my phone, I could flash the stock rom back and restore it to working order via LGNPST. I know it is simply a software issue, because prior to my rooting the phone it was recognized by the computer.
Does anyone have any other solutions I haven't tried? Or is this something I need to go JTAG on?
