Hi.
I tried flashing CM10.1 on a Nexus S device, but now I'm stuck at a boot loop. The main problem is that the device's volume up key doesn't work, and I can't get to the fastboot menu by going power + vol up. Is there any other way to get to this (maybe by adb)?
Or to put the phone in download mode and just flash a stock ROM image, any help is appreciated.
You have two options.. you can try this the pc tool... or the usb jig (here) to get to the download mode.. Hope this helps you..
HTC m8, was running CM12 latest nightly with twrp.
I was trying to revert to an earlier build of CM after failure to install MultiROM was creating UI errors. Now my phone is stuck on the CM animation and I can't reboot to recovery mode to access twrp. Power and volume up reset but don't access recovery mode. USB connection on my computer is not recognized so I can't send adb commands to reboot to recovery. Any help would be greatly appreciated.
You need to use power + volume down to get into recovery. Press and hold power + volume up until the phone reboots. As soon as it restarts press and hold power + volume down until it boots to hboot.
Thanks!
I thought I had tried that earlier but apparently my timing was off.
So, I got my new OnePlus One today and I tried to get CM12 onto it. I was following the [GUIDE] How to Install CM12 on the OnePlus One- Android Lollipop/5.0 on the OPO forums, and everything went well until I tried to get the TWRP on there. I flashed the recovery and rebooted the phone. I turned it off and then tried to boot it into recovery but it doesn't, it just hangs at the OPO logo until I hard-restart it.
I've tried factory resetting it and doing
fastboot oem unlock
but nothing happened. The factory reset pretty much just reset the phone. I think I might've messed up the kernel. How do I fix it?
EDIT 1: I've tried reflashing twrp recoveries and nothing. When I hold power+volume down, it powers on, shows the one plus logo, then reboots and just goes to the lockscreen.
UPDATE 1: I managed to manually flash all the CM12 files and use lollipop. I haven't tried the recovery yet but I'll keep you guys updated (if any of you even care).
UPDATE 2: Apparently flashing CM12 made the recovery work. Everything works as it should and the OTA to the most recent CM12 worked perfectly.
You're probably doing the button combo wrong. Hold volume down, then hold power (so you're holding them together), when you see the boot logo let go of power but keep holding volume down until you reach recovery.

I was curios and enabled advanced reboot to try and boot into recovery and it worked (after I had flashed CM12). Everything's working now.

How did you manually flash CM12? I think I'm having the same trouble you were having. I used the oneplus toolbox from the forum to unlock the bootloader, then flash the TWRP, but no luck in getting into recovery mode. It just boot loops with the oneplus logo until I release the volume down button at which point it then boots to the lock screen.

@Heisenberg I'm also having trouble getting into recovery. I've tried the different button combos (power + vol down; power + vol down and release power) as well as the advance reboot options to get into recovery, but they all fail. I get the 1+ logo and after I let go of the volume down button the screen goes black and boots again to the 1+ screen and then to the lockscreen. It's almost like it doesn't recognize the recovery. I tried putting the stock recovery back on using the image in the OnePlus One toolkit folder, but that one doesn't work either. In addition to unchecking the "CM Recovery Update", are there any other settings that could be causing problems?
For background info, I initially used the toolkit interface to unlock the bootloader and then flash the recovery. The bootloader unlocked with no issue...it wiped my device and I was in sync with the "How to root" video posted by alex.inthi. I got sidetracked after the (seemingly) successful flash of TWRP onto the phone I kept getting booted into the Cyanogen recovery. I realized out that I needed to uncheck the setting to keep it from overwriting TWRP and after that was not able to boot into recovery. After finding your beginners guide (thanks, by the way, very well written) I tried using fastboot from the command line as you show, but still no luck.
Thanks in advance for any help...

Okay, I must have been having a special kind of moment - I've got TWRP 2.8.7.0 running on my handset now. I may have been holding the volume down button too long, or it may be that I was using an older version of TWRP, but I'm going to go with the former. I've also been able to successfully flash and boot into Philz 6.59.2
Having the same problem
I am having the exact same problem and cannot seem to find a solution. Recovery screen just doesn't appear, but goes to lockscreen.
Tried erasing, flashing both twrp, philz etc., but nothing works. The phone doesn't recognize the recovery status. Advanced booting does the same.
Update CM-recovery is checked off, phone is unlocked. I've followed every step of the big guide down to every detail.
Is manually flashing the 12.1 ROM the only way and in that case: is it hard for a relative newcomer?
I have a rooted and twrp installed samsung s6 from sprint.
I tried to install xposed through twrp and now it boot loops. I guess xposed has a boot loop issue on stock samsung roms.
I can enter download mode but I can't get into recovery because the phone will not power off! If I hold key combinations to power it off it just keeps restarting. Does anyone know a way i can enter recovery mode. I do know i can flash the stock firmware through odin but i dont want to lose all my files. Is there a way to disable xposed through odin/download mode, or through adb if the device is offline?
Thanks in advance.

I had the exact same problem two weeks ago, but I was able to get into recovery mode. I'd hold Volume Down + Power buttons to restart it, then quickly switch my fingers to Power Up and Home button to enter recovery. Try it that way, it could work.
Also, you should try to install this xposed. I am on a stock ROM as well and this one works for me!

Thanks for your help. I ended up accessing recovery by plugging in a usb and using the keys combo you suggested and am now running the xposed you linked to. Thanks a bunch!

Same issue here! The os does not boot for me either anymore, twp freezes, can't restore because I can't get to the bootloader

Alright so to get to the bootloader, you have to plug in your phone into the charger/PC while holding the Vol Up + Vol Down.
Edit: If it does not show up on odin, install the samsung USB driver/android studio. It might help with that
