[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?

[Q] Any chance of recovery from bricked state?

I was upgrading to Cog 9.1 using 2e recovery and I think my captivate is now bricked. It does not display anything (only black screen). Even after connecting to USB I do not see the battery charging symbol. Is there anyway out of this mode?
I have tried all the different key combos to try to get into download mode. I could always get into download mode earlier using down button + power button combo.
Any pointer will be very helpful.

How did you flash, and when did you realize there was an issue
Captivate
Cog 2.2

I flashed using ROM manager and I realised the issue after the screen remained black for around 30 mins.

the volume buttons and power combo are used to put it in recovery. Mine got stuck on the at&t logo. I pulled the battery after about 40 minutes, turned it on into recovery, wiped my data, rebooted, then worked flawlessly. My advice -> pull battery, put it back in, hold volume buttons, then connect the usb while continuing to hold up/down volume buttons, this should get you into download mode.

This sounds like i9000 rom button combo. Won't work with COG. For recovery hold both volume buttons and hold power button in. When at&t logo shows up, wait about a second and release the power button but continue to hold the vol. buttons. Should get you there.
For download, hold volume buttons down and plug in usb. Should put ya right there.
If you have a cappy that has the no buttons bug, you're pretty much hosed.
Designgears has a thread in the development section about the 3 button issue, with a mod that fixes it. Give it a read.
If you had usb debugging enabled and the computer sees the phone, you should be able to use adb to reboot recovery or download too.

[Q] Galaxy Verizon refuses to turn on

I have Galaxy Tab from Verizon and I tried to upgraded to Gingerbread but it didn't work and I couldn't get into the recovery mode to downgrade it back... I took it to some guy who said he can fix it but he couldn't, instead it now never turn on and only shows that its alive when I plug it to wall charger (it shows the mobile-triangle-PC image) it doesn't do that when I connect it to PC or without being plugged to anything!!! Power + Volume down does nothing, same for Power + Volume up!!!
Any suggestions?

have you held the power button till it turns off while plugged in? If you can force it to power off, you may be able to get it into download mode and go back to stock firmware that way.

I tried doing so before, after 7 seconds of holding the power button, the (mobile-triangle-PC) image starts to flash (go and come back) on 1 second pattern until I leave the button, it then gets back to the stable (mobile-triangle-PC) screen

[Q] Sprint HTC ONE stuck on white boot screen

Hello,
I've just installed this ROM after wiping Cache/Delvik Cache and system wipe.
Now the phone is stuck on the boot screen and I can not get back into recovery to sort it out.
I held down power & vol+ buttons to get into recovery but nothing happens. The Home & Back buttons flash after 3 seconds then nothing happens.
Any thing else I should do to get into recovery ( TWRP)
My friend whop is a member asked this question on the Developers forum and so far no luck.
we have tried the following:
This is suggested by chogardjr: Plug your phone in to charge. Don't use a USB port for power. After you plug it in try the hard reboot again.
PLEASE HELP
Just for the sake of testing... Have him hold power without holding the volume. It should force reboot, not to the bootloader, so he can get a feel for how the reboot works. It can be finicky during a bootloop cause there are processes trying to run in the background. But it should do it if you hold power long enough.
Edit:
Also find out if the charge light comes on when he plus it in.
Tried and no joy.......

I had a similar problem with a bad kernel flash and could not get the device to shut all the way off - thats why the keys are blinking. I plugged it in to a charger, left it like that for a few seconds, then unplugged, held it under a bright light and waited. After a few more seconds, it shut all the way down and I was able to boot to recovery in the usual way (power+down). You may have to try combinations or maybe not. But, you won't get to recovery until the phone shuts all the way down. High light under in the 'eyes', plugging and unplugging, and holding the power button for up to 30 seconds are all known ways to do this, but as was said before a bootloop has processes trying to run, so the machine can be 'confused' and have difficulty shutting down. Hope you are successful...

Thanks. I actually got it going with one of the answers posted for me, by powering it off under a bright light.
Sounds daft, but it works.

[Q] Bricked an S-OFF HTC One

Hey,
I bought an HTC ONE M-7 from a user who was running it on a custom Rom and had it S-OFF.
While trying to put stock Rom on the phone via the pc, the pc crashed in the middle of the process and the mobile stopped responding. The phone stayed in this condition until the battery ran dry. Since that moment, the phone doesn't turn on by any combination of hardware buttons as mentioned on different forums. While plugged in to a power source the screen just blinks on and off.
I would be highly obliged if anyone can help me out of this situation.
