[GUIDE] How to Enter ODIN and Recovery Modes on Verizon Galaxy S III

---

Not sure if this is the proper section for this but thought I would post this here as I'm sure it would highly assist people in development and other tasks. This is the button combinations you need to enter each mode.

ODIN/Download Mode

• Make sure your device is completely off
• Key Combos: Volume Down + Home
• While holding both of them simultaneously press the Power button until you see a disclaimer on the screen
• Then let go of all the buttons and press Volume Up to accept the disclaimer
• Once the green robot is visible on the screen this indicates that handset is in now ODIN/Download mode

Recovery Mode

• Make sure your device is completely off
• Key Combos: Volume Up + Home
• While holding both of them simultaneously press the Power button
• As soon as the phone vibrates, let go of the Power button but keep holding Volume Up + Home
• When you see the "Samsung Galaxy S III" logo (not just the word "Samsung"), right after that, the next screen you should see is your recovery
• Don't let go of Volume Up + Home until you see your recovery

Updated OP to correct that Samsung devices do not have a "Fastboot" mode. ODIN mode replaces this and the ODIN software is basically a set of fastboot commands which is the only way to communicate to the device on a low level. Just a little FYI for everyone.

Heimdall should also work ,and it's cross-platform, unlike Odin. But somebody with a phone should test it to make sure it does.

Thanks for this handy information.

Since I am not at all familiar with Odin and how it works, could you ad a description of the steps to take in order to use Odin to flash an image file to the Galaxy S III? I watched a video on rooting, but the author never really showed much of the Odin screen on his PC and didn't say anything at all about how to use it. So far I keep reading to "use the PDA button", and I have the files downloaded and ready to go, but I don't want to make any mistakes.

Happy rooting

Thanks. I guess it's really pretty simple after all.

I've seen some posts where folks had Odin still chewing on the process after 45 minutes. What do you recommend one do in that instance?

In 99% of cases such as that it is likely the fault of a bad USB cable or the computer itself. First try another cable, if still the same try to get access to something like a laptop and try there, usually USB ports work fine on laptops.

You would think so but I haven't seen anyone have any luck with Heimdall on Verizon. If someone out there has gotten it to work, would appreciate some sort of guide.

Thanks. Luckily, I did not have this issue, and your thread here allowed me to root easily on the first try (I did use the OEM USB cable, having read that sometimes prevented problems for others). So thanks a lot for this thread. I am one of a presumed many who came here as this thread was spawned from a divergence on a previous root thread. Glad I did.

I did have an issue with Rom Manager while trying to flash CWM Recovery. It hung on the first attempt and I had to reboot the phone, but then it worked the second time. The only remaining anomaly I have here is that the nandroid I made is dated 1970. I'd like to know if others are having the same issue, and await some announcement for a fix. Does CWM Recovery actually have a support site? If so I'll post there about it.

Happy to help.

And the date bug is a known problem with both CWM and TWRP recovery so far so don't worry too much for now and it won't affect it's use, just an annoyance. No ETA on a fix just yet but check in ROM Manager for an updated version possibly.
