[Q] Problem booting into Recovery

So.... Been playing with this for the last two days trying to root this phone.
I've rooted a few other phones, so I do have experience with the overall process, but I am unable to even boot this phone into Recovery. I have tried booting into recovery by holding down both volume buttons + power and from adb terminal "adb reboot recovery."
Neither method works. The phone will boot (or reboot from adb) and brings up the "at&t World Phone" screen and then nothing else appears. The first time I tried this it actually wouldn't boot up even after pulling the battery and trying to start normally, it still sat at the same screen. I let it sit all day today at the screen until the battery died. I was finally able to get it to boot up earlier.
If anyone can help, that'd be greatly appreciated. Let me know what info I need to add.

I usually just press and hold both volume buttons and power then release just the power button and keeping the volume buttons still pushed on the 2nd time the white at&t screen pops up... Works for me every time.

hold volume up+down and power key btw this is wrong section to post supposed to be in general

Oh sorry, didn't realize it was supposed to be posted in general.
I've tried the Volume Up/Down + Power and this does not work, as I stated originally.
I've also tried to do it from the adb shell, which also does not work.
Does anyone have any idea why I can't access recovery?

I"m having a similar issue. Holding volume up+down and power and releasing in any combination just boots the phone up. If I just hold volume up+down and power the phone alternates between the AT&T World Phone screen endless.

Yes u have to let go of the pwr button when the phone screen turns on

I've tried just about every combination of the Volume Up/Down + Power and no luck.
I've also tried the following ADB commands, with no luck, it just reboots the phone:
adb reboot recovery
adb reboot-boatloader
When I hold Volume Down + Power I get the a Yellow Triangle with a Android guy with a shove with the text "Downloading... Do not turn off Target!!!"
When I hold Volume Up + Power I get an Android guy with the following text: "POWER RESET or UNKNOWN UPLOAD MODE"
For kicks, I tried to to flash a rooted update.zip via the Volume Down + Power way with the Samsung update software, the same way I have done with the Samsung Moment. Wasn't sure if it'd work, but worth a try.
Any one else have any ideas or suggestions?
Phishie, do you have a final release version? Or anything special about the phone you have?

I just press the two volume buttons first (to make sure theyre pressed before you hit power), then press the power button, as soon as the screen turns on, I let go of everything and it works just fine, no need to have ridiculously complicated instructions.
The trick is to make sure both volume buttons are pressed BEFORE you hit power. Then release. Easy as pie

Also, if you guys are having too much trouble, just download the one click root/unroot. It will run, boot your phone into recovery, then all you have to do is scroll to install packages with volume key and hit power. Done.

Trust me, I am making sure I'm pretty the keys completely. I've literally tried it fifty times by now.
And I've also tried the One Click Root. This does not boot the phone into recovery either. It just sits at the AT&T World Phone screen forever and will actually get stuck here and will not boot up normal even by pulling the battery and powering it back up. It'll just get stuck at the for-mentioned screen. I have to connect it to adb and reboot it there to get it out of the loop it's stuck in.

that doesnt sound good. Maybe you need to try a factory reset? are you running stock rom and everything?

When I first got the phone I did a factory reset.
Yea, it's completely stock to my knowledge. But I have a different ROM than the final release version that everyone else has. This is a pre-production device.

same problem
I try all the combos as well, no luck, would the combos be different for 2e vs 3e recovery?
I try combo, it powers on, the same thing happens, the at-t comes up, goes for a second, then screen brightens, wait a bit and then the home row buttons light up, hangs there... doesnt matter which kernel or which rom I flash, same thing, adb and other stuff wont work as they need usb debugging enabled, which mine isn't.
Is there a way to mod the phone files and flash to enable usb debugging? Anyway to remap the buttons to 2 button vs 3 button?
Everyone post your methods for entering recovery please?

Recovery Mode with three buttons

I have read over and over again that you hold down both volume buttons, and the power button, and it'll boot into recovery - but it's never worked for me. Last night, by accident, I let go of the 'up' volume button, only the 'down' was down along with the power button and low and behold - recovery mode. Is this proper procedure maybe only for certain phones? I was so frustrated, all that would happen with three buttons held down is the AT&T logo screen would flash on and off. I guess I'm just looking for affirmation here.

It's always been a fickle thing for me. I just use ADB for recovery.
Turn on USB Debugging, open cmd prompt in Windows, navigate to where you have android\tools, then adb reboot recovery
I prefer it because it is reliable. I know I can do hardware keys to recovery but I always seem to require 3 or 4 tries before I can pull it off right.

Thank you - I'm definitely going to have to get more familiar with ADB. I have it set up, but I've never used it. Reliability is what I want, I really don't like the panic attacks in the middle of a ROM install!

Let GO
I think you missed an important step of the process of getting into recovery.
After you see the AT&T screen the 2nd time, LET GO of the power button.
Some phones are quirky about which button to let go of, and according to some posts, european builds do it with just one volume button and the power button. (I think)
Anyway, glad you got there, but be sure to let go of the power button next time.
Out of curiosity, does download mode work?

I can get into download mode with Odin no problem, but not with just the buttons, unless I'm doing that wrong, too.
I did try letting go of the power button, but all that did was boot the phone.
These things are so tricky, and the panic swells when it doesn't work and you're trying to flash a ROM for only the second time in your life!

I know the feeling... when your heart starts racing in your chest..
Been there.

Hello everyone,
I cant use the 3 button combo at all to get to recovery mode. I've done the "Down Vol., Home, and Power" before and it worked. However, i am not able to get to it after i flashed Bionix-v 1.2, and 1.3. I pretty sure its not because of the ROM, but i just can't figure it out WHAT! I've tried the "Vol. UP, Down, Power" as well, but still not luck. Please help!
Thanks,
Yahase

Turn your phone off, and plug in the USB cable. That worked for me.

While your phone is switcher off, press and hold both the Up and Down buttons in the volume. And then plug in the USB.

Power button is broken? How to reboot to download?

Power everything was working this morning
Noticed that my power button wasn't working...the screen stayed on. Pulled battery, put it back in and the phone booted without pressing power.
Was like "wtf?"
When it booted, I couldn't turn off the screen.
So I just left the battery out and took it home.
Put a new rom on phone, thought "This will fix it."
Wrong.
Had to flash using Rom Manager because in recovery the power button doesn't respond.
When it began to boot "AT&T Screen" wouldn't disappear and show me some Doc's v4.
I can manipulate it to boot into recovery but the power button doesn't work still.
I can NOT get it to go into recovery.
Can someone helps me?

have ODIN open, and battery removed from phone... hook up usb, hold both vol keys, while inserting battery... you should get download mode fine even with a busted power button... what you do next is up to u....

Once more, I can NOT get it to boot into recovery in that fashion.
I cannot place batter in the phone without it attempting to boot
(doesn't not get past the AT&T boot screen)
I cannot plug it up, hold volume buttons and then put in battery because it will just charge. If I unplug the phone, the phone still thinks it's charging actually.
My question really is Can I 'fix' the power button, or can I reboot it into download mode through command propt? I've never used ADB to access my phone, so that'll be new.

Dude... recovery is useless right now, you have a busted power button... and because of 'said busted power button', none of what you're trying to do is going to work... like youve said...
You are down to trying to force download mode with USB cord, holding the vol keys, and inserting the battery... ADB cannot run commands to a phone stuck at the boot screen... Thread title says, how to reboot to download, and with the button like it is, all you can do is what i've posted...
As to fixing the power button, i don't see why that's not possible... do u feel it press at all?

Yeah, it 'presses' and 'clicks'. I mean it worked most of the day, it got low on power and it just quit working.

Any luck forcing download by puttin the battery in while the usb is hooked up with the vol keys pressed in?

I was having the same problem with my power button and eventually the power button stopped working completely even though i could still hear it click. I sent it to mobiletechvideos and they fixed it really fast and it was a great price.

goes into boot-loop like if I were holding the volume up/down and the power together. That's what doesn't make sense.

And I could buy another used Captivate for $50. I have an upgrade in less than 3 weeks and this happens

It happened to me once before after flashing a bad kernel. I just did what B-Naughty had suggested. Remove battery -> plug in USB -> hold both volume buttons --> then insert battery. Put me right in download mode and Odin it back with a working power button. Unless it's really a hardware problem, then you're out of luck...

Oh in that case imo i would get another used captivate and wait for the sgs 3

Maybe if I went to a store and sucked up to them they'd let me upgrade a month early (especially since I was initially supposed to upgrade in October)

Might be down to getting/making a USB jig if it don't come up... but if you upgrade to gs2, the jig will work for that model as well so won't be wasted...

Maybe a jig would work. But easier, funner solution is adding a line for a Moto Atrix 1 for just a penny plus the $36 fee. Problem solved. Thanks for the help for what could just be a hardware failure. I'll upgrade my other line later when the SGS 3 comes out

[Q] Phone can't boot, vibrates once, then twice

Hey guys, I need some help...
Long story short, I wanted to restart my phone one day after a Market app wasn't working, and when I turned it back on, it would load the ATT screen, show the Galaxy S screen as well, but then the screen turns black and about every 15-20 seconds, there would be 1 vibrate, a pause, 2 consecutive vibrates, and this would continue to go on forever until I took out the battery or the phone died. I had 2.2 but cannot get into recovery mode or download mode, even with the 3 button combo. Am I screwed?
Thanks for your guys's help!

You probably need to build/buy a jig and use that to get to download mode. Otherwise, try this:
Take out battery
Plug in usb cable
Hold volume+ and volume-
Pop in battery
This should take you straight into download mode. You'll could try doing a factory reset while in download mode but you'll probably just have to flash a new ROM/Stock Image

I agree with this technique, although in my experience, you should hold down both volume buttons BEFORE plugging in the usb cable to your phone. It should take you right to download mode, and from there, I'm sure you know your way around. Best of luck.

Actually that particular order doesn't matter. It works both ways. All that matters is when the phone receives power (battery put it) it has the USB signal, the vol+ signal, and the vol- signal.

Is my note 9 bricked?

Hello everybody,
First of all, please forgive my time to time poor english. I tried to fill in my presentation and hope it's ok.
I also want to thanks all the developpers that make a great job to optimise and/or improve stock roms and to help people like me that are not so good in developping.
Let me explain my problem :
I've just bought the Samsung note 9 SM-N960F/DS I was dreaming of.
when I put my sim card inside (a french one) he went on a firmware update, and my phone changed for a french CSC (XEF). Thus, I losed some functions I like, such as SpO2 measure in Samsung Health (I know, it's not so important but...). I couldn't also force the sound in earplugs when phone whas ringing, even by using "Soundabout apk" that was working with my note 4....
I don't know why Samsung changes the available functions regarding the country as we pay the same price for in fact a bunch of functions !!!
I tried to come back to the initial CSC, by flashing an official rom, and following a tutorial on XDA site explaining how to do without rooting, using combination files.
But I certainly made an error as my phone has restarted in a curious mode named "kernel panic upload mode" that I cannot escape. It's impossible to go back to download mode, even with combo like vol down + start button, or other combinations of buttons.
This phone wasn't rooted and i'm afraid now as I don't know how to flash a working rom on it. Whem I use Odin, the flashin fails at beginnig (at setup connection step).
Does somebody have an idea or a solution to fix this phone?
I join some picture of the current state.
Thanks for your answers

Hello Enzyne,
Thanks for your help !
I tried Vol up + Bixby + start, vol down + bixby + start, vol up + start, vol down + start, vol up + vol down + start, but nothing works.
I can't go back to recovery mode nor to download mode...
Odin says "added" but can't setup connection...

Have you flashed with this PC before using Odin? Can you possibly try another PC? Maybe different USB cables just to eliminate possibilities.

I used stock cable, given with the phone.
I gonna try with another one, and on anotehr PC... Maybe will I be lucky... But i'm not optimitic...

It could be that the drivers are no good. It is also possible that you may need a warranty exchange. I'm not aware of any other boot-loader level recovery process besides odin. Maybe even try another version of odin that is known to work with our note 9.

The Kernel Panic Upload Mode doesn't prevent the phone from booting to Recovery.
1. Make sure your phone is completely powered off.
2. Press and hold the Bixby button and the Volume up button.
3. Press and hold the Power button. At this point you should be holding down three buttons. Don't let these go until you see the Recovery screen pop up.
That's really all there is to it. If you have a case that goes over your buttons it's possible you aren't pressing down hard enough for one or more of the buttons to register.

Not to nit-pick,but,when the phone is fully powered down,the simultaneous 3-button push can be released as soon as you see the Note 9 splash screen & the recovery screen should pop-up within a few seconds.
Only reason I mention it is possibly the OP is experiencing issues by holding one or more of the buttons in too long,(just spit-ballin' here on this point)............

Hi Koliosis, and thanks for your help.
In fact, I even cannot power down the phone !!!
The only thing he does except showing kernel panic is to quickly flash on samsung splash screen when I push together vol down and power button, before to go back on panic kernel screen:crying:
No splash screen with bixby + vol up + power buttons combo...
The problem came after a failed flash with combined files (the good ones for my phone, I verified...)
Is there another way to reinitialise the phone except via Odin or Smart switch?

To get the Note 9 into download mode, do the following:
Turn the device off. Hold the volume down and Bixby button together and then plug in your USB cable that is attached to your PC. Your phone should go into download mode.
As this requires the phone to be off, you may get lucky once the battery runs out of charge.

I've never had an issue with holding the buttons too long, but I have had an issue with not holding them long enough. I let go of the buttons as soon as the Recovery screen comes up and I haven't once had an issue with that. I think he'd have to hold the buttons for several seconds past the Recovery screen booting up before this caused an issue.

Okay, now we're on the same page. You have to be FAST with this.
1. Plug in a charging cable. This will give you the LED charging indicator on your phone.
2. Hold Power+Bixby until the charging indicator turns off. Once the charging indicator turns off you have to be VERY quick with step 3.
3. Press and hold Power+Bixby+Volume Up until you see the Recovery screen.
I was stuck in a bootloop after installing a Magisk module, and this happened to me as well. Every time I would power the phone down it wouldn't stay powered down. I had to be very fast to get into Recovery. It took me a couple of tries to press and hold the buttons quickly enough. That was partially because the case on my phone made pressing the buttons a bit more difficult.

Is there another way to force connection with the PC in order to flash a rom again? Another "magic" application like odin but more powerfull?

The only thing that im aware of is very legacy like QPST. Im not sure if QPST is able to handle the newer phones tho. You can definitely ruin your phone with it too.

Hi again Enzyme
I looked on Google for QPST. But it seems it's only for Qualcom powered phones... mine is Exynos powered. ..
