First you are going to READ All this before executing anything. It took me a long time to write this, you should at least read it.

Please understand that we can not disconnect the battery!! So every time we press the POWER longer than 5 seconds TAB mimics a battery disconnect. Guess what, if you let the power button pressed after "Samsung" Logo shows, it will power of again!! This is what I suspect is your problem!!!!!!!!!!!!!!!!!!!!!!.

One you see Samsung Logo you need to release the Power

.

Also, The original Command for Samsung Download Mode is [Power]+[Volume Down]+[Menu]. But in fact mine just go in Download without [Menu], just [Power]+[Volume Down] and release after Samsung logo.

Since our TAB 10 has a big screen it makes a little difficult to navigate on recoveries. I found that the best is a CWM improve version called Philz Adv CWM 6.55.0. You can read moonbutt74 tread at http://xdaforums.com/galaxy-tab-3/development-10/clockworkmod-recovery-6-0-5-0-gt-p5210-t2830871

This will send you to: h__p://d-h.st/users/moonbutt74/?fld_id=38524#files

And I will suggest you download =>http://fs1.d-h.st/download/00136/SSY/PhilzAdvCWM-6_55_0-gtP-5210-v2.zip

1)First you need to feel comfortable. Realize that your tablet screen is a BIGGG button. Once you are doing the Dangerous stuff, if you have butter hands you can get in trouble easily. I do preferred to work with my TAB3 in a Flat surface like a table. Hands away if you do not need to touch anything.

2)Google and Youtube is your friend. I try to search for a video on TAB3 10 Recovery but no luck. So please look at:

Samsung Galaxy Tab 3 ClockWorkMod Recovery Install =>http://www.youtube.com/watch?v=XolmtyvS3Yk&feature=youtu.be

That is for a 7" instead of a 10". You only need to realize that the [MENU Button] is on the side in a 7#. TAB3 10" [MENU Button] is on in the bottom (Land Scape). Use ONLY the software that applied to you particular model. Ignore the software names of the video.

You can have more videos at:

3)First turn on Tab and in Android OS Play with your buttons and verify they work. Learn to know what is your [Power] [Volume Down] [Volume Up] & [Menu]. Set clear in your mind that the [Volume Down] is the closes to the [Power].

4) If anything Fails you can get in to Download mode with adb command. But Please note that I will suggest you to figure out first why the volume method is not working, you will need them in the future. Be smart!.

See this video =>http://www.youtube.com/watch?v=NPYCpbMoWkQ

It show you how to use Googles SDK adb. Downloading SDK takes for ever. This what I will sugest you use. Instead use "Minimal ADB" by going to to this page http://xdaforums.com/showthread.php?t=2317790 READ that page too.

Download Version 1.1.3 for windows =>https://docs.google.com/file/d/0B1S0LCuXCnnmSWh6NGJmSE1BUWc/edit?usp=sharing

As you will found installation will create a Shortcut in you Desktop. Using that "Minimal ADB and Fastboot" Shortcut will make the first 5 minutes of the previous video useless. So you only need the last minute where you type "adb reboot download". But here is my explanation:

a) Hook your Tab3 to the PC

b) Use "Minimal ADB and Fastboot" Shortcut

c) Verify that you Tab3 is recognized. Type in "Minimal ADB" the command

[COLOR="Blue"]adb device[/COLOR]s

If you find your self with this

C:\Program Files (x86)\Minimal ADB and Fastboot>[COLOR="Blue"]adb devices[/COLOR]
List of devices attached
12345678901234 [COLOR="Red"]offline[/COLOR]

This means you device is offline. To repair go to: Settings>Developer Options>

Now Unselected "Usb Debugging option" and reselect.

A Windows Pop Up, Click "Ok"

now lets try again adb devices

C:\Program Files (x86)\Minimal ADB and Fastboot>adb devices
List of devices attached
12345678901234 [COLOR="Blue"]device[/COLOR]

Success! is connected.

d) Now type in the Minimal ADB CMD window "adb reboot download" [Enter]

adb reboot download

You will see your tab turn off and reboot in Download mode. Now you can use Odin.
