Default bad flash - stuck in os

hey guys,

i was bored and flashed a .zip on my phone and now I'm no longer bored. Long story, short... I'm booted into the os (almost) with constant errors popping up. I can't get the power button down for 10 seconds to reboot phone and i want to get back to recovery to flash by back up. How can I use terminal (mac) to force back into recovery if phone is not in mode for adb to recognize phone?

Thanks in advance.

Try hold power button + volume up to force reboot. Once the screen goes black release those buttons and hold volume down button to go to hboot

Thanks for your reply. Seems the power + volume is not be recognized. Is there a way with fastboot or adb?

Otherwise, I guess I wait until power drain.

Power + Volume Up should work. But as you asked for adb/fastboot

1) "adb devices" to check if device is recognized
2) "abd reboot bootloader" so the phone reboots into bootloader
3) go to recovery and try a reflash

This should always work as long as the screen is on. It might take 10 seconds or more, so you may not be holding the buttons long enough.

Alternately, you can use:

adb reboot bootloader

or

adb reboot recovery

There is no required more for adb commands, as long as the screen is on. Fastboot on the other hand, requires the phone to be in fastboot mode.

What did you flash? Was it a ROM, and if so did you do a full wipe (data, cache and Dalvik) before flashing?
Please click the "Thanks" button if you found a post helpful!

Thanks for all the replies. It finally died and I was able to jump back into recovery. I was trying to flash a .zip (one+ one theme) to my rom and some things about it (audiofx) was not liked. I guess adb could not recognize the phone since it was basically booted into the os. I just thought there was a way to still use adb or fast boot to push it into recovery. I did not get to try adb reboot boot loader, but would adb recognize phone even with this command?

Glad it worked and that we could help a

adb reboot bootloader should be recognized nearly any time.
