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?
I tried to update my rooted HTC One but it seems that something went wrong. The phone will not boot. When I hold down the power button the home and back buttons start to flash. I have tried to boot into the bootloader by holding the power button until the home and back buttons stop flashing but all that does is turn the red LED on and the screen stays black. How do I fix this so I can use my phone again?

The buttons are supposed to flash when you hold down the power button. After the buttons stop flashing, quickly release and then hold the power + vol down buttons. That should work unless something really got messed up.

Hello.
I have managed to brick my I8190N, by installing TWRP through this app https://play.google.com/store/apps/details?id=com.jmz.soft.twrpmanager&hl=en
I can't access recovery, download mode, and I cant even get the phone to boot. When I hold down the power button, it displays the S3 Mini logo for a few seconds and then blacks out. After that, it wont show anything on the display even when I hold down the power button. But when I pull the battery and reinsert it, I can turn it on again for a few seconds.
The problem started with me installing Virginity V14 over CM 5.1.1 Then i couldn't get it to recovery mode anymore so I thought i'd reinstall recovery through TWRP MANAGER app from google play store. After that the phone went bricked. Also, my Home button and back button are not working, because the flex cable is broken. I used virtual buttons to emulate these. Now I've hears that you could get to download mode when holding vol dn + home+ power although i've gotten there with vol dn + power buttons before. So I would like to know shall I order new buttons from ebay, or what else are my possibilities of getting the phone working again.
ty in advance.
Fix the buttons!!
Fix the buttons dude!!
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
My Samsung galaxy tab s8 ultra is stuck in a boot loop. I need to hard factory reset but it doesn't seem like power button + volume up the bootloader/download screen. Is there any other way to hard factory reset this?
Try plugging it into your computer and then holding down volume up and volume down at the same time. That can get it into download mode. You may need to try holding those buttons at different times. But try to do it right when the screen turns black at the next boot loop and then continue holding them down until it shows download mode.
If it doesn't work after a few tries, then try unplugging it from the computer and plugging it in again and repeat.
Mine was stuck in a Samsung Dex boot loop. I got out of it by pressing power + volume down, entering safe mode, and then doing the hard reset. Also if you are able to turn it off completely then hold both volume buttons while you plug it in you should get into Odin mode

Yes! That's the exact loop I'm in. I tried both power + volume up and power + volume down and it would just keep booting up normally then load Dec and reboot.
Volume up and down plugged in worked. Thanks!

I just wanted to thank you for this tip, as it also helped me restore my bootlooping Tab S8 this week. Really appreciate you sharing the clue!
Be well,
