hm... tried that but it just boots the phone normally.
tried just pressing and holding "BACK" and consecutively pressing "BACK" to no avail.

Have you installed cwm from market then installed into phone.
What I mean is cwm has a 2 stage install 1 install app
2 open app and then click install on to phone.
The shut down menu will not show reboot option. you have to shut down then restart manually when you see sony logo press/spam the back button constantly until cwn loads, if this not work try using down volume button again spam/ pressing continually

make sure that CWM is installed correctly

On xperia Arc S you need to press a few times the VolumeUp and VolumeDown buttons as soon as you see the FreeXperia logo. You'll notice that the led becomes violet when you're entering into recovery mode.

got it working, guys.
downloaded Xperia CWM Auto-Installer from market and worked like a charm.
thanks for all the help.

works great

First you'll need a rooted and CWM supported kernel. Shut down the device. Press the power button and wait. When the boot logo came wait for a little vibration. Then press the Back or Volume Down button several times. There you go. You're in Clock Work Mode Recovery.

Are you using Team Win Recovery Project or Clockwork Mod Recovery?

Your USB plug isn't plugged into the computer while attempting to get into recovery, right?

nvm.......

Galaxy Nexus unable to boot to recovery.

Hello,
I have a Galaxy Nexus GSM. I rooted it and unlocked the bootloader using Galaxy Nexus toolkit a while ago, and flashed the 4.1.1 stock ROM (Build number JRO03C). Yesterday i received a notification for a system update to 4.1.2. I hit download, phone rebooted into recovery, i chose to flash the rom and everything seemed fine, however i'm still on the older version 4.1.1. Now, when i try to boot my phone into recovery (VOL_DOWN & Power Button) it shows me the boot screen and says "Downloading, please do not turn off" and i can't do anything. If I hit the power button again the phone reboots normally. Any ideas what I can do?
Sorry if I am at the wrong section.

Volume down and power is the key combo for Odin download mode. You want volume up, volume down, and power. This will take you into the bootloader. From there, you can use volume up/down to scroll to recovery and press power to load into recovery.

That used to happen to me.....I later realised that it's Coz of the update....well simply return to the previous version of the app and re-flash without the upgrade. Hope it helps u out too.

The OTA won't flash if you have changed any system files or you're not running stock recovery & radio & kernel ...

Thanks a lot! So how can I restore the Odin mode from applying the update? Reflash the ROM?

Look at the stickies in the general forum. There is one for flashing an OTA & one for flashing a stock ROM, take your pick

Stuck at Start screen, Downloading...

Hi guys,
I flashed the carbon rom this morning and the wrong GAPPS. So now when the phone boots to the OS I am stuck in a loop from the setup crashing. I figured I'd just reboot into recovery mode and re-flash (I've done this before with no problem) the carbon rom with out gapps. When I press the power and volume buttons, I get to the Odin Mode Start screen, but below the android I see "Downloading... Do not turn off target!!!". If I press the power button it just starts up the ROM and I have no option to go into recovery mode.
How can I flash a ROM without getting into recovery mode and USB debugging off (since I can't get into the OS to turn it on because of the loop)?
Help!!!
Thank you

Go into boot loader (Vol up +Vol down + Power button when phone is off). Then choose recovery mode (volume buttons to scroll and power button to select). From there you can wipe data reflash rom and gaaps. I recommend using a different gaaps package

That's the problem, I don't have the recovery mode option. All I see is "Start".
