Samsung Galaxy SII LTE (SGH-I727R) - Android Q&A, Help & Troubleshooting

I have a BIG problem. The volume down button does not work. For this phone, I am supposed to hold both the volume up and down buttons and the power button in order to get into recovery mode. Is there an alternative for somehow getting into recovery?
Also, I want to root this device, but I am running Jelly Bean 4.1.2 and the only rooting methods I could find is using Odin which requires the volume down button. Then there is the SuperOneClick method or Zergrush, but as far as I understand, these rooting methods only work for this phone if it has Gingerbread.
Any ideas?

Bricked S2?

I recently soft bricked my new AT&T S2.
I have clockwork recovery installed (4.0.0.2), and the only buttons that work are home (goes back to the first menu), volume up/down, and power to hide the menus. I can't select anything at all, it seems like I have the international version of the recovery, not one for the S2.
Anyways, I can't get into download mode by holding down the home + Vol up+ power, and Odin can't seem to connect to my phone if it's in clockwork recovery and not download mode.
Would the jig work? Or is having no ability to boot into download mode pretty much a killer? I can access my phone through ADB, I just don't know my way around adb as well as I would like.
Is there any way to flash a different recovery via ADB? Any other solutions to get my phone up and running again? Because right now it's not booting at all.

[Q] Tmobile stock rom for galaxy s3

I was wondering that what if I flash tmobile official rom for s3 to my international version unlocked s3, can I have access to tmobile's 4g lte?
One more question, since I rooted my phone, so when I press volum down+ home+ power button into recovery mode, the recovery mode is the original one or it is from cmw which installed in automatically after successfully rooted? I used the root method from here http://forum.xda-developers.com/showthread.php?t=1695238
Thank you all.

Galaxy Tab will not boot into Download Mode

I recently went to flash the UK 4.0.4 onto my US tab, but the device will not boot into recovery/download mode. Pressing the power button on the device while off does not immediately turn the device on but it does come on after a couple tries, but holding volume down does nothing. I'm currently stock unrooted rom. How can I fix this so that I can flash (or root) again?

I have the same problem. Can anyone help us, please?
Thanks!
Have your turned it fully off or are you starting from standby?
To boot into Recovery/Download modes you need to start with the tablet completely off. I find I also need to be holding the volume key before I press and hold the power button.

[Q] safe mode 4.1.2, 4.0.4 volume button ,camera problem??

I have a i9300 s3. I upgrade to 4.1.2 jb , my phone become safe mode. however i try to get out but i failed.
1. restart by press back button
2. restar by press volume up button and other also cant get out from safe mode.
downgrade to 4.0.4
I press volume down key+ home key + power to downloader mode, and downgrade to 4.0.4 by odin. after downgrade 4.0.4, i go to recovery mode, but my volume own button not working. i use odin running to cwm recovery mode, press up volume button until can wipe factory reset and reboot, it' out of safe mode. but the volume down button no working after boot. When I press volume down key+ home key + power it still can go into downloader mode.
After 1 week, my phone auto download software upgarde and install to 4.1.2, but it cant cause cwm recovery mode disturb it. after that my camera no function at all. now i wanna try to go downloader mode again, but my phone volume up button also become no working at all to go downloader mode, but it working when the phone is on.
Actually whats was going on?? how can i upgrade to 4.1.2 ?? or i just can stay at 4.0.4 but now my camera no working.
Anybody looking for this problem before?? :crying::crying::crying:
That's one hell of an unlucky upgrade. I don't know mine upgraded/rooted without problem. Can't you just return to stock once you're able to enter download mode?
Fail to understand the problem be specific with current problem .

First thing, and i don't pretend to be rude, write your question in the right way.
There are Forum Rules for all of US.
The second one, the download mode, is by pressing volume DOWN(not up)+HOME+POWER. The one you are choosing as far as i comprehend by you спасибоwords, leads totCWM (either stock or 3d party one).
The third, if you somehow managed to downgrade to ICS(4.0.4), just press OTA update
Cheers!

Actually when the phone boot on ICS 4.0.4 the volume up button is working and the volume down button is not working.
Ya, i know that the download mode is by pressing volume DOWN + HOME+POWER.
I can going to page WARNING!! a custom OS --------------- after need press Volume UP to continue and Volume DOWN to cancel, but the volume up and volume down button also not working.
Maybe is because my volume DOWN button problem, so make me headache.
I know that CWM (either stock or 3d party one). But i need it to wipe my factory reset after downgrade to 4.0.4 by Odin.

When it was JB 4.1.2, It will boot on SAFE Mode, However how many times i reboot , reboot by press back key or up volume button too.
I cant get off from SAFE mode.
At the moment, I try to downgrade to ICS 4.0.4 by Odin. I can going to download mode. after Odin pass, It stuck at the samsung logo.
I try to go to recovery mode by press VOLUME UP + HOME + POWER. I can go to recovery mode but the Volume DOWN not working and i cant go to wipe reset.
I going to download mode again and running PDA with CWM tar. I use CWM recovery mode to going to wipe reset by press VOLUME UP button only. Pls try to understand this.
Once I wipe reset, I can boot my phone on ICS 4.0.4. The moment all function ok, camera too. Just the Volume DOWN button not working.
I use it for a week, Software upgrade automatic but it failed. It stuck on CWM recovery mode. I try reboot again, the Volume UP button is WORKING, the camera not working. The big problem is I cant go to download mode again, just stuck a WARNING page, and my volume UP and DOWN also not working when i stuck a warning page.

Whats I going to try is tomorrow I will buy the USB JIG and force my S3 to download mode and try upgrade to JB 4.1.1 or 4.1.2 the latest Version ( March ) by Odin again. Any suggestion too??
try installing phillz touch recovery in odin using the tar file you can use touch to go up and down also try installing stock 4.1.2
Or you can just issue an ADB reboot download

I also have a button stucked, which you can easily see in the bootloader, as it scrolls automatically all the options. It is hw issue, but wanted to know if there is a kernel or someway in which I can disable the volume rocker entirely.
Is there anyway to disable safe boot when booted up into safe boot. I can install apps but they will not open due to the fact that I am in safe mode. Anything will be greatly appreciated.

Samsung Galaxy Tab S 10.5 T805 - Can't boot into download mode

Hello everyone,
I'm trying to root my tablet, and as usual with any tutorial, I'm getting stuck on what should be something very simple, booting into download mode. I've seen instructions asking me to press and hold the volume up,/down, power button and home button, in various combinations depending on the tutorial.
Either way, holding the volume up or down doesn't make a difference, I can only seem to boot into recovery mode and can't get into download mode at all.
Anyone know a solution to this? Have samsung made it impossible to root after update?
Please help
