Volume up button disabled - can't get into download mode

Hey guys, I've bought a galaxy s2 (t-mobile) and tried to root it. I held the vol up and down button while holding the power button, got into "press up to continue, down to cancel" screen, but I keep pressing up and nothing happens?!
The volume up button does work when the phone is on and I can make the ringer louder, but not during the download mode. Is there a fix?

are you trying to get into download/odin mode? if so you hold up/down and insert the usb cable while still holding down the up/down. I didn't think power button was involved in the matter but maybe there are 2 ways. Anyhow, try that maybe it'll work.. Did you update the phone to ics thru kies yet? Maybe that flash could do something helpful..

Sorry, I did mean that with the holding up/down button and USB cable. I am trying to get into download/odin mode. But I only get to the screen where it says to push volume up to continue, or down to cancel. It is the right screen, I just cant push up, nothing happens...
Also, I did not try to update the phone to ics thru kies yet. How do I do that?? You mean the regular software update in the settings menu?

Ok, so I updated to 4.0.3 via Kies and now have ICS on the phone. I tried booting into odin/download mode, and once I'm in the warning screen "A custom OS can cause critical.....bla bla bla.....Volume Up: Continue, Volume down: Cancel (restart phone), the volume up button does NOT work and still seems disabled.
The button itself (up button) is not broken, as it works when the phone is on to make the ringer louder.
Any other ideas? I'm really confused why it won't work ??

Anyone? Any help would be great

same problem here

If u can get into recovery mode and r using cmw hit both up/down buttons at the same time. Ill take a thumb and place it in the middle of the buttons then push them (dont hold them tap them) after doing this itll say something like rockers disabled or something like that. When I used cmw Ive done that a few times and didnt know it and when in cwm I couldnt use the volume buttons anymore to make a selection. Do this to enable the buttons in recovery mode I never noticed if it only took effect in both modes or just in recovery mode but its worth a shot.

Recovery menu???

For the life of me I can't get the Vol Up + Vol Down + Power button combo to bring up any menu options in the recovery mode on my Galaxy Nexus. This is a GSM from the Play store. I'm running stock Jelly Bean setup. I was trying to unlock the bootloader and do the factory image install, but I kept getting a boot cycle. I tried to go into recovery to data wipe, but I couldn't ever get the menu options to come up, just have the Android on his back with the exclamation point. Anyone else see this?

that is the stock recovery.
press power and vol down and up and you'll get the menu.

Wait, let's see if you're not confusing things.
To unlock: with the device off, 3bc (3 button combo) power+vol up+vol down. Hold it until you see bootloader screen. Connect the device to pc previously set up with fastboot, and in a command line, type 'fastboot oem unlock'. Accept on the device.
When in recovery (accessable by using volume keys in bootloader screen, also allows to reboot bootloader, start system), press vol up (or vol up+power, can't remember right now) to see stock recovery menus.
Nevermind recovery right now, follow efrant's guide on flashing stock/unlock. Set up fastboot. Don't use toolkits.

Ok my phone is now flashed. But I still can't get anything to show up in stock recovery. I can get to bootloader and volume up to recovery then I get the android on his back with bang. No button combo here brings up any menu options.

Awesome, thanks! This actually works, not sure why the 3 button combo wouldn't get it every once in a while. Is the 3 button combo used for the CDMA VZ version of the phone? I even saw this used in a youtube video!

Nope. It's power and volume up to get into the recovery menu from the recovery screen. Power and volume up and down is to get into the bootloader.

I tried power and volume up. Nothing happened!!!
I flahsed back to stock.... and got bootloop. since I didn't flash data image.
Edit:
Ok got it. press power button first .follow by volume up.

[Q] Won't start after rooting with odin

I try to root my S3 with odin now the only thing i got when i turn it on it's a few second of Samsung image and after that it's vibrating and nothing more.
I try to reboot it with the volume button down or up and nothing too
PLz help it'a a S3 from Rogers(canada) SGH-I747M

To reboot in download mode you need to press all together : Volume down, home button and power. In clockwork mode you nee to press : Volume UP, Home button and power and them let go all when you see Samsung galaxy S3 logo with litte blue writing on left top corner.

Are you booting into recovery mode correctly ? Hold home and volume up and then hold power until it flashes...then let go

Yes the only thing happen i saw tje samsung logo for 2 secondes and the phone vibrate and the screen turn black

Since I'll assuming you flashed rooted firmware, you need to access recovery to wipe data/factory reset and wipe cache in order to proceed. Which root method did you use?
Recovery mode: Vol up + home + power. When your device vibrates, release only the power button

And if it doesn't work you can force it into downoad mode by holding down the power. volume down and power key without the battery and then putting in a micro usb cord plugged into the computer. Then put in the battery. Thats the hard way haha
Or get into recovery and clear all cache and factory reset.

Which Odin did you use?
I've been using the one from this thread: http://forum.xda-developers.com/showthread.php?t=1822308 and never had issues.
Gotta make sure you download the one for Rogers.

So you successfully got it into download mode and flashed the stock rooted rom with no issues?
If so then you need to wipe data from and cache in order to eliminate the bootloop.
Again, recovery is: Vol up + home + power. When your device vibrates, release only the power button

Stock, can't get into recovery/download modes

Hi guys. Im pretty experienced with android but this one has me stumped. My buddies brother has a stock/non-rooted optimus g e971 on Rogers. He changed his screen lock password and forgot what it is. Of course he never register a Gmail account so I can't recover that way. I figure no problem. Shut down, pwr+vol down to factory reset. Well nope doesn't work. It flashes the lg logo twice then boots like normal.
Ok so I figure I'll just put it in download mode/fast boot to do the factory reset. Tried pwr+vol up. Nope. Vol up+vol down+pwr. Nope. Vol up+vol down and plug usb+pwr. Nope. It just flashed the lg logo twice then boots like normal. I've tried multiple variations of each holding the pwr for different lengths of time, always with the same result.
Anyone have any suggestions? It's not bricked, and the vol keys are working, it just won't go into any modes.

also I dont know if he has hardware encryption enabled (of if thats even an option on this device) but would that even prevent me from getting into factory reset / download mode?
Also I check that the vol rocker is working. when it is on but screen is off, if i click the vol rocker either way it wakes the screen.

I have a similar problem.Here's a thread I made about it http://forum.xda-developers.com/optimus-g-intl/help/enter-download-mode-t2883542.A couple of guys had some ideas.None worked in my phone but maybe you're luckier.
If you haven't done that already you should try going into download mode by pressing power up+down and plug the cable, don't press the pwr button.
If you find a solution pls let me know .

Yup, you shouldn't need to press the power button for download mode.
First, make sure you have the LG United Mobile drivers installed on the PC you're using. Then plug your USB cable into the PC (not the phone yet). Simultaneously press and hold the Vol +/- buttons, and hold for 10 seconds. Then while still holding the vol buttons, connect the micro usb to the phone.

Doesn't work either. If I hold +/- for 10 sec then plug in the usb it flashes the lg logo twice, then goes to the battery charging screen. If I hold +/- for 20 sec then plug in the usb it flashes the lg logo twice then boots like normal.

after reading this post i went and tried if i also cant get into the recovery and the same happened to me, the LG logo just flashes and nothing happens. mine is stock E975 (4.4.2).

worked for me.

Android has SD card encryption disabled by default - but if it was enabled it shouldnt disable recovery/fastboot - right?
Even if the bootloader is locked, i should still be able to get into fastboot/download mode, and/or recovery, right?

That's what i figured, but i didn't know if there is some quirk with this device i wasn't aware of.
Is it possible i have a corrupt boot loader? Again this device I'd completely stock.

anyone?

Jacked up my T800 by forgetting to update my bootloader -- is there any hope?

First off, I'll openly admit I'm an idiot and missed the bit about needing to update the bootloader on my T800 and now my tablet won't do anything other than sit at the Samsung boot screen.
I've tried doing the power button + volume down + home button key sequence but it just reboots. Same thing about switching to volume up after it goes dark. I'm not sure if I just haven't gotten the sequence down properly or if it's just a lost cause at this point. Does anyone have any suggestions?

If you've held the power button, vol down and home button simultaneusly the device should boot to download mode. At that point you would select volume up to enter the mode. Are you sure you are holding these long enough and that the device is not plugged in?
If you are on a 7.x.x. rom then you may be having the same problem as me. If you came from the Samsung 6.0.1 rom then you already have the right boot loader.

Plug in charger and then power button all you need to do is stop the boot loop so you can get it in to the mode you need......

Thanks, stinka318. Right now, it's stuck in the Samsung Galaxy Tab S boot screen and will sit there until the battery runs out. Are you saying plug it into power right now and hit the power button or do I need to let the battery completely die then plug it back in so it's powered off to start with?
Thanks for the help!

If I hold the power button, vol down and home button down simultaneously, it will reboot the device but then go back to the Samsung Galaxy Tab S boot screen. I've tried holding that down until my fingers go numb (how long have you had to hold it down for?). I've also tried letting go of the vol down and moving it to vol up once the screen goes black then releasing the power button when the Samsung screen comes up but that doesn't do anything either. Everything that I've ever tried just ends up showing the Samsung screen. So frustrating!
Thanks for the help!

Yep plug it in now and hit the power button it will show the battery charging icon from that you should be able to do thing you need to recover it.

boot into download mode (was mentioned how to do it on this thread already), go to ODIN, flash the bootloader, boot into twrp, wipe everything (to be safe), and flash your desired rom
