[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?

Ativ S Blue Screen After Boot

I have bought a Second hand Ativ S and it turned out to be dev unit, it worked for the most part(occasional crashes), but recently it broke.
After it boots it gets me to a blue screen and then powers off. I can still access the download mode and the system files via USB. But I want to do a factory reset of some sort or at least be able to use it.
Can someone help me out with this? Is there a possibility to re flash it? or is there a combination of buttons i don't know about?

have tried to hard reset the phone by this steps?
If you can't access your phone's Settings page:
1.Turn off your phone.
2.Turn on your phone again by pressing the volume down button until you see the exclamation mark
3.Then, reset the phone by pressing the following four buttons in this order: Volume up, Volume down, Power, Volume down.
4.Your phone should now reset and restart itself. (It might take a while for the process to complete.)
And it didn't work for you? If not you have go to a Samsung store, probably they will flash you a normal OS to your phone...

I've tried that...it didn't work. I've also went to Samsung and apparently it made it worse. Initially my problem had a blue screen after booting but after I took it back from service the blue screen has disappeared and now the phone just powers down after the boot. THe guys at Samsung told me that the don't have the device number in their database and that the cannot do anything to it....so i'm hopping that some tool will pop-up and I'll be able to flash the device from home.
Also being an Engineering unit when I power the device based on your description it doesn't show me an exclamation mark it just goes dark and if i hook it up to the pc it shows as mass USB storage, and I can access the files on it. So there is something i'm missing for this device in particular.
Thanks anyway for your support.

Thank you again Jackson5...Really...Thank you, i've almost lost hope...after seeing your post and replying to it I said ....what the heck...lets try that again, and it worked...not with your steps exactly...I put the phone into a charger and it started to power up...Windows logo power down..and again power up and shutting down....Meanwhile I pressed Up on the volume and the exclamation mark appeared. and from there, suffice to say that I have a phone, again. So Thanks again

Same problem, help...
It seems Ive got the same problem with my Ativ S, I've tried everything and nothing is working...
Sorry, but can you tell me what buttons exactly and in what order did you press to get to the exclamation mark screen, please? I am sorry but I really cannot understand your explanation (your post) very well, you said:
"Windows logo power down..and again power up and shutting down....Meanwhile I pressed Up on the volume..."
Do you mean logo + power or logo + power + volume down or something else? I cannot understand the part "again power up and shutting down" either...
Thanks

If the phone powers down due to blue screen or any other problem you might encounter, connecting it to a power source will make your phone restart...so basically what happens is the Phone powers up reaches the error and shuts down, but because is plugged to a power source it will power back up. So while you are plugged with the device keep pressing those buttons... Having a Dev unit apparently it worked with the Vloume Up ...
-Press the Volume Down Key + Power Key to turn on the unit
- Still hold the volume down key, the release Power Key.
- Wait for the startup screen booting with an exclamation mark " ! " then release the volume down key.
- Press the following buttons in the following order: press the volume up (high volume key) ==> press volume key down (low volume key) ==> press the power key ==> press volume down key.
- Wait a moment and look at the screen, a message such as loading new software will start the hard reset process

Cheers, I'm stuck in here and i can't get further.
My machine is an T899 Engineering version

cannot enter bootloader mode

Hi XDA,
I follow the instructions to enter bootloader mode. After switching off the phone I press power and volume down buttons at the same time. The phone wakes up and boots up normally. I've tried different periods of holding the buttons.
Please help.

First hold volume down, then hold the power button.
When it begins to vibrate instantly release the powerbutton and keep the volume down pressed until you get into fastboot

Thanks, it worked! Not so straightforward as it seemed at the beginning

he repeated as often as necessary for you to run the shortcut

Note 5 volume button broke stuck in safemode.

Hi my volume button down is broken and everytime it boots it's in safemode.
Whenever trying to access recovery it normally boots up when buttons are pressed.
Booting into download mode freezes it, I have to do a hard reboot by pressing all the buttons.
Volume/power button work fine when in use.
I've opened up my phone to disconnect my volume button it stills boots up in safemode.
I've tried 2 new roms still in safemode.

Hello brother,
Even you flash 2 new roms still booting up safe mode, bad seen
i feel your volume down button was keep pressed maybe,,,,,maybe (it should be b coz of dust or something else).
to be confirm is that your volume button broken or pressed follow the steps below
1. switch on your mobile release the power key and Press again the power key and wait till finish the boot, (if the device get restarted it means we can confirm your volume down button was pressed & hold)
2. press home button & power button check if the device is going to download mode ( if you stuck press power button u will get exit)
how ever try to clean the volume down button inside and pull slightly. after turn on your mobile.
if your damn sure volume button was broken not working at all, then lets think about it

Cannot reboot into recovery.

Whenever the device boots it gives me a security warning and press power button to continue message. Because of it I cannot reboot into recovery because even when I hold vol up and power the screen comes up and i need to let go of vol up for it to register at which point phone boots into system.

Well, the keys need to be pressed before the phone boots up and I think you also need to be connected to a PC, otherwise it won't work. If you're able to boot into system then adb reboot recovery should also do the trick

I usually do use the adb method. But I would like to use a method that is more reliable. My problem is that intermediate screen that appears before the samsing s20 fe screen that warns the bootloader is unlocked and device is unsafe and requires power button to be pressed by itself. It does not register when I have vol up pressed down. And when I release to press power and no matter how quickly i go back to pressing vol up + power the phone starts booting into system.

The phone decides its boot method as soon as the screen turns on, that's why I said you need to have the buttons pressed and connected to the PC way before it even turns on.
Once it turns on and you get to that warning screen you can let go and just press the power button to continue and you don't even have to hold the buttons anymore.
Just do what I tell you and you'll be good
I think holding the buttons after pressing the power button to continue will make it boot to system I think, but I'm not sure lol

Can you get to fastboot? Is this an A/B device?
You can write to the misc partition to tell it to go to recovery.

Well i had the same problem, here is how i solved.
First, you need to have a USB-C cable connected to a PC, if not you can do everything right but it wont go to recovery (and i think not even on Download Mode).
Second, shutdown the phone, don't just reset.
Third, Volume up and Power (keep it holding
Once the security screen come, take off the power button and with the Volume up, quickly take off and press again.
It should go to recovery.
Side note:
hey @ShaDisNX255 , nice to see you here.
