Has anyone figured out the magic incantation for forcing a reboot into recovery? A very long press on the button seems to force a reboot, and holding it even longer will just keep cycling normal non-recovery boots.
Ive been doing exploratory stuff in this thread: http://forum.xda-developers.com/showthread.php?t=2795998
I have instructions on how to boot into recovery using ADB
If you can't do that, maybe its a combination of screen touch + button?

I’ve got an AT&T Captivate that is stuck in 3e recovery, because it won't recognize when I use the power button to select "reboot system now."
Some background:
It was stuck in a boot loop running CM7. I re-installed éclair to take advantage of 2e recovery. Rooted it, and intended to put a version of UCKB1 without 3e recovery, so I could install unsigned files to prep for a re-install of CM. Apparently I flashed the wrong rom or the flash got corrupted. I can’t get it into download mode. Tried using a jig, tried using one-click unbrick. I can’t even use ADB, since it is in recovery.
Any help would be amazing! Thanks in advance.
Does the phone boot all the way to Android or does it still loop?
Did you use the jig while in recovery?
you have to use it on a powered off state.
Just yank the battery and either try the jig while powered off, or if it boots correctly use adb while it's powered up.
Thanks for replying. The phone does not boot into android, it gets stuck in 3e. I used the jig with the phone off. (I did try with it on just for kicks, but no joy.)
The phone "recoginizes" the power button when I try to turn it on, it gets to recovery, and then won't recognize a butten press in order to boot the rest of the way.
Thoughts?
Fixed it
Re-tried with a newly made jig. Must have blown a resister last time. Works now. Thanks for the advice.
I have this same issue intermittently, usually after a modem flash in cwm3. The txt will pop up saying that the back button has been disabled. A battery pull and restart and it reboots fine. Just a mystery to me...
Yeah that happens from time to time.try to Hold both volume buttons. That will sometimes re-enable the back button.
Ionno why that happens....
Some recoveries i've seen used back button or home button to select...just saying might work

Yeah some recoveries not all, I know specifically in boog's kernels, you can use the capacitive buttons.
Settings = down
Home = up
Search = select
you have to cycle from the bottom to the top... i don't know why it does this..
Hit down repeatedly until you end at the top. the power button will work.

You are either doing it wrongly, or the volume-down button isn't working. It's as simple as that.
To diagnose, make absolutely sure that CWM is properly installed by following steps 1-3 in this guide.
EDIT: Actually, if volume-down isn't working, you won't be able to start the phone in NVFlash-mode either.
Then try to start recovery again (also by doing it exactly like the guide says.) If you still can't access CWM, then you know for certain your volume-down key is broken and you need to get the phone repaired.
Maybe a "quick shot" but why not to ask: do you keep power and vol down keys long enough? You have to keep them pressed both for quite a few seconds before CWM mode is activated and CWM menu appears. So, just power off your phone, then keep power and "vol -" buttons pressed until the LG logo changes a bit or the CWM menu appears. On my phone it takes about 15 seconds, so no hurry
Hopefully you all don't sigh or roll your eyes at my questions, I came from iOS 2 weeks ago and the Android learning curve is pretty damn steep!
Many guides I read says to enter recovery mode by turning the phone off, then holding volume down and power buttons until the screen flashes and you should enter right into recovery, especially guides to flash a rom. I installed TWRP last week and the way I enter it is hit restart with phone powered on and as the phone begins to restart hold volume down only, then I enter it.
When I hold power and volume down when the phone is shut off, I get the HTC boot image as the phone is rebooting and then a message saying something along the lines of the phone will reboot and it counts down 3,2,1 then the phone reboots a second time and not into recovery. Plus my wallpaper gets removed. I rebooted but the wallpaper was still removed.
Two questions; Is this some sort of faulty installation of my recovery? Which way should I boot into recovery when about to wipe and flash a rom? Thanks a million!
twrp quicker reboot...

way i do it is i unlock the screen hold power down to get the power options screen then i select reboot i wait for the screen to go blank then i hold the power and volume down it will load into bootloader then i just hit whatever boot loader has the recovery on it (twrp 2.5... had a problem wouldnt do system boot just take me back to recovery so i had to do to bootloader then restart from there) then you will hit recovery i would do a factory wipe but dont have it delete anything else just do a normal factory wipe and maybe delete cache and your problem should be fixed unless there is an issue with your rom you are using then if it bugs you that much find a different one.
another not when the system reboots i think you can just hit volume down dont have to hold power also but im so aggrivated with my current issue i just hold power also to make sure it goes thew.

*Update*
Ok so after trying again to enter bootloader from power off holding volume down and power button, the same thing happened where I got the 3 second countdown but I continued to hold the buttons and I correctly entered into bootloader. So my question then stands, when flashing a new rom does it matter which method I use? (Reboot, volume down or Power on, volume down/power)
Thanks

Hi,
I'm very new to rooting and such and only followed guides a read forum posts to get to where I am now.
My phone is rooted with stock ROM and SU, the bootloader is unlocked but no S-OFF (don't think it's possible on the mini 2 yet anyway). The new OTA update last night installed when I got home and charged my phone, then the phone just shut off and every time I tried to boot it would go straight into TWRP without showing splash screen or bootloader (even when holding power and the volume down button). When it's in this state the touch screen doesn't work and the power button only locks the phone. Holding power + vol down in this state doesn't do anything.
I have to let the power drain completely to get the phone to boot back up but it immediately boots back into recovery and then I can use ADB to force the bootloader to appear, but when I flashed the stock recovery that I found in these boards, it messes up the screen and all it shows is static with some artifacts. I have to let the power drain again to get back into the bootloader, and from the bootloader I can get the android OS to boot but I'd like to fix this completely.
I guess I should also mention that even after flashing the stock recovery the phone will still boot back into TWRP after I let the power drain so I think that means that the stock recovery isn't taking?
The twrp problem you mentioned is known, hope it'll be fixed soon. Are you sure you typed the right command to flash stock recovery? Fastboot flash recovery recovery.img?
If you get stuck, the combination is power button and volume up, not volume down...

Unfortunately I was using the wrong ADB command, I was typing "fastboot boot recovery.img". This seems to have fixed the problem so far but I have yet to try rewriting TWRP back to the phone and I probably won't until theres a fix or unless I need to.
Thank you for your help.

I had the same problem. It happens when I reboot with my phone when charging.
You can reboot your phone by holding vol up+power button.

Wife hands me her tablet the other day and it is stuck in safe mode. Using notification shade link to turn off safe mode simply reboots to safe mode. To make this worse, the other method of on/off safe mode is to hold vol down with power. It seems the volume down button has failed. When android is running, pressing volume up raises the volume as normal, pressing volume down does nothing. Same in recovery, volume up works, volume down does not.
Looking around for solutions, I stumbled on this:
http://forum.gsmhosting.com/vbb/f777/how-exit-safe-mode-samsung-phones-simple-solution-here-1727011/
which claims to allow safe mode disabling with root. Ok, so I figure I need to root the tablet, no big deal. Well I'm stuck, I can't get it to work.
I've follow every guide I can find. Most all of them start with rebooting to download mode. The standard method is to hold volume down again, can't do that. So instead I use adb (adb reboot download). The use Odin to flash TWRP - no go. Every instruction I can find also says to hold volume down after Odin finishes the flash. Just powering off, and then holding vol up + power + home doesn't get me anywhere. I can boot back to android, reboot recovery, and it is only the stock. Even tried flashing a nougat (supposed) version of CF autoroot. That does something more, because the boot screen warns me that SE Andriod is not enforcing. But even that simply ends with rebooting to Android, no root. Interestingly, the last step in the CF Autoroot says "Restoring Stock Recovery", not sure why.
Ok, so there it all is. I'm stuck. Anyone have any ideas
a) how to get safe mode off with no vol down button
b) how to actually successfully root the latest nougat (again, with no vol down button)
Any ideas are much appreciated. Thanks

I doubt it's failed. Your volume down button is probably just stuck down which is why it continually boots to safe mode.
Volume up would still work.
Pop the back off and check the contact under the button isn't stuck down or get the vacuum cleaner hose with the slim attachment , place it over the button and it MAY just be enough to release it.

You could be right. Wouldn't know it by the feel of the button. It feels perfect. And being in safe mode won't let me load any app or anything that might tell me one way or another.
I'm trying to avoid cracking the tablet open because I'm not sure I'd be able to fix it at all once I did. Probably can't physically see any issue it might have with the button. Plus it looks like a royal pain to open. But in the end I might be forced to try.
Anyone know a root method that doesn't involve volume down?
Terrible to think that the whole device could be rendered useless by a button that isn't critical to its use. (can turn down volume by hitting vol up and then using the slider on screen)

You can get root no problem just by flashing a rooted Magisk boot image, but I doubt going to help with booting into safe mode as that button combo is hard coded.

Well if root does not allow disabling of safe mode, then I'm out of luck. But this link indicated that it could work. I've never tried so I'm just grasping at anything.
How exactly can I install a rooted boot images without the following:
- No ability to install a playstore or any other app (no magisk manager)
- Can't get TWRP to install (presumably because this is now blocked by latest firmware?? Not sure but it fails for me following the Odin instructions I find here and elsewhere) I think this requires vol down button - at least all the instructions call for it after flashing TWRP with Odin
I have ADB and Odin at my disposal, but I can't seem to get Odin to actually install TWRP. CF Autoroot (for Nougat) does nothing either.
Am stuck in safe mode please my volume is not working galaxy tab 4 please help
Did someone solve this issue? I am also stuck with a non functioning tab due to one stuck button...
Stuck button
I had a friend with this issue. I was able to use a sewing machine needle to pop the button up. Make sure you tape or protect the side from scratches. Also, you can try holding down the volume up button. It's a meaningless combo so it may boot.
