[Q] Problem booting into Recovery

[MLBZ521]

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.

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.

 

[MLBZ521]

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.

 

[commander2k]

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

 

[MLBZ521]

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?
