You need to force it into FastBoot mode i believe. This can be done easily by the following:
1. Turn off the phone and wait 5 seconds.
2. connect the USB cable while pressing the VOL + key (Volume Up)
3. Keep pressing till the LED light turns blue.
4. Follow the steps of the tutorial. There are plenty out there. Google it. One such thread in XDA is

Also, you can find a Video Tutorial in the sticky section of this thread. The link is

Hope this helps.
EDIT: Also make sure this is an unlocked phone. Refer the Xperia U Development thread for more info.

I am trying to root my tab following these instructions, http://www.thedroiddemos.com/2011/08/28/how-to-root-the-samsung-galaxy-tab-10-1-video-walkthrough/
but I can't get the tablet to boot into download mode? I am using stock 3.2 update and when I hold the volume down and power after a few seconds the samsung logo comes up but then thats it. It will just keep restarting with the samsung logo booting up but I don't get the option to ever boot into download or recovery mode, it keeps skipping that part.
Any help would be much appreciate and I did try and search first before I posted.

You need to hold power and volume down at the same not one followed another

sorry I didn't mean followed by power...I am holding volume down and power at the same time and that is what happens.
There was another thread where the solution was posted. I think you have to tap the power then hit both once you see Samsung. If that doesn't work search for the other thread.

That worked, thanks
This is trickier than it seems. The only way I could make it work was:
- press the Vol- button.
- while pressing it, press the power button
- when the Samsung logo appears, let the power button go but keep pressing the Vol- one
- wait until the download/recovery screen appears
- let the Vol- button go

Yes, this is the perfect way to get into download mode
i keep seeing tut vids with everyone holding buttons down till you see the flashes etc. however if power down completely then just hold the vol down for 1 - 2 sec, then give the power button a quick push (no need to hold it down at all. just press it like you are turning it on) while continuing to hold vol down you'll go straight into boot loader (release vol down when you enter bootloader).

Erm, no disrespect intended, but isn't this how we've always gone into the bootloader? I didn't realize there was another way, outside of an APM in a ROM or through ADB.
Nite sure if this is what you're looking for but I use "quick boot" from the market.
One click for reboot, recovery, bootloader or power off.

I forget the button combination. But you can always do
Code:
adb reboot-bootloader

Green led - flash mode (connect USB while press volume down button), may be you mix up and down buttons, up button is upper button, near power button!
You have simlock, only way to unlock it is to buy new phone.

Hi All.
I might be missing the obvious here but how do you get into recovery on these things?
I've read loads of posts and tried various combinations with Vol+/- and Power, Wait for the light then do the same..... Nothing!!
I've put root on it it but left the bootloader looked. The device says I can unlock it if I want. It's the 16GB Wifi model (UK)
Any ideas where I'm going wrong?
Thanks

Maybe you;re mixing the fastboot method and cwm method on your head..
if you're question is how will you get to recovery then my answer is VOL UP.
power on your xtz and when the "SONY" shows up simply spam the vol up and you're good :good:

Thanks for the reply. If I'm reading what you put right, it's:
Hold Vol up
Press Power
Wait for Sony logo then ? Not sure what you meant by "when the "SONY" shows up simply spam the vol up"

Haha, Thanks for your help. I appreciate it.
I'm laughing because I still haven't got a clue what SPAM VOLUME means so I'm going to go for HOLD VOLUME.

LOL, I even ended up on the Urban Dictionary... I'm thinking..Oh no, it's one of those young people phrases again!!
Thanks again for the help though, I'll get that dual recovery installed I think. I'm not even planning on flashing it. I just want a good backup.
Hello Zach181,
have succeeded in holding the vol up ?
I have the same trouble and can't access the recovery mode.
press power on
wait for the sony logo to appear
hold the vol up button
but nothing happens, it boots in the normal way.
thanks
Let's try to make it clear.
The device does not come from factory with any button combination that can get you into any recovery.
You need to flash a custom recovery first.
The process for "XZDualRecovery" is to wait a second after the sony logo appears and then when the notification light turns green hold Volume Up for CWM, Volume Down for TWRP.
Might be different for other recoveries, but at least try this method.
Let me clear it too...
its NOT HOLD
but SPAM or KEEP PRESSING
:good::good::good:

What works for me is HOLD the correct volume button, but not from the start, but from the time the LED turns green.

I must admit that I have put it in fastboot but only if holding from the power on and not pressing repeatedly. I've been too engrossed with my new toy to try much but I will sort recovery today.
So what we are saying is...
No recovery Installed
Power and hold Vol up = Fastboot
Recovery Installed
Power (Wait for light) Vol up = CWM ---- Vol Down = The other one (Forgot the name)
That still leaves us with fastboot mode with recovery. Would that be as I said at the beginning of this post... Power on and hold Vol Up straight away (Don't wait for the light)
.
Hi guys! i been reading entire posts for 2 days and cant find any way to boot in recovery mode (volume up + power, volume up plus down and power, etc) i just push power button until sony logo, any idea why is not working?? btw any up to date rom to flash it for last option? (SGPT121ES/S)

not sure if i will be of any help or you already figured it out. but what once worked for me is to press power as soon as you see sony logo right away let go and hold volume up only. but quick like. than continue to hold volume up. if not try volume down same direction. i think the button changes if your rooted.
