Happened to me too. Pressing power and both vol buttons at the same time will reset or get you into bootloader screen if you keep holding the buttons.

Lol I thought I was going to be the only one to give myself a boot loop like that. Glad you fixed it though.
For reference though, it still accepts adb commands during boot loops, so you can always "adb reboot recovery" and restore through there next time. My boot loader wasn't letting me choose any options when I screwed my N7 up
Also, holding power for approximately 10 seconds will instakill the power. So thats another option

[Q] Cant Get into AP Fast Boot!

I accidentally,... . unknowingly wiped the RED "system" button in Safestrap 3.12 on my Droid RAZR M today. (I was suppose to be wiping the cash and dalvik, but missed) I'm a retard I know. :crying:
Now I cant get into AP Fastboot to restore the phone from this hard brick!
When I press the power button along with the volume buttons, the only thing that happens is the red Motorola 'M" appears for a few seconds then the safe strap screen appears with the little sad robot, but that's it no AP Fastboot. Pressing the on screen buttons to enter Safestrap Recover do not respond. Oh boy I'm afraid I really did it this time. Its on the charger but i don't know if its even charging with out as OS?
Battery power was at 60% before i bricked it (i think). RSD Lite or my PC for that matter don't even see the phone when its plugged in.
Can this be saved? Or do I need to take a trip down to the Verizon Wireless store?

You need a different key combo to get into fastboot. You're not permabricked tho - that's just a really bad softbrick

Really? Well I hope your right. It gives me some hope. lol So do you have any idea of what alternative key combo i might have to use? Thank you for the reply.
Try holding power & volume down until the screen flickers then hold power and both volume buttons. You gotta be quick
If your boot loader is locked you won't be able to fast boot back until the new fast boot files come out though if your on 4.1.2

New to this, i accidentally the whole phone, same problem im in AP fastboot but registers as Device Locked
run through it on windows OS but says 'Fastboot" is not recognized as an internal or external command" and doesnt reboot as said
this process took 1min
Halp
This thread saved my life, then killed me. The suggestion about the different keys was spot on, i got into fast boot mode, then ran that utility. It totally failed me, I must have killed my phone pretty dead, and now there are no more key combos (the suggested one worked at first but now its just making the screen go blank) to try to get back into fast boot to try again. any more suggestions? on the up side verizon just pushed that update so i figure i can blame that to attempt an exchange
Did you take the update before using that utility? If you did, which version did you use? If you were already updated, then you needed to run 1.20. If you ran the wrong utility, that will cause issues. Now, since you can't boot, it sounds like your battery is dead. When you get to the blank screen, plug it in and leave it to charge for a while.
I'm no expert by any means but I'll try to help as best i can. If not me I'm confident someone else will. Now, I apologize because I didn't understand your original post.
Could you elaborate a little more please?
1. What were you trying to do with your phone prior to things going wrong, if they went wrong at all.
2. you mentioned AP Fastboot. So IM going to assume that at least you can access it. (not the same problem that I was having) that's a good thing! lol
3. Are you utilizing a utility like the one by Matt? Or are you doing something else? Like flashing firmware etc.
4. What were you in Fastboot for? What were your intentions?
I hope this doesn't come over a condescending. Just trying to get a Clearer understand of your issue so we can help.

Could you help me please?
I changed 2 lines in my build.prop file so i could see if I could get touchless control.
After I changed it, I restarted my phone. Now it is stuck in the Red M Boot, and it stays there, dosent black screen, dosent boot. I can get to the boot selection menu, but i cant choose anything, they all end up at the Red M. I Read that I can fix it in AP Fastboot, but I can get there. Also if i force it off (with power button and volume button) It just goes back to the Red M.
Everything I do ends up at the Red M
Help fast please, its my only phone, and I just got rid of my house phone

Holding the combination of buttons will only cause it to reboot, every time. Holding the power button down will make it shutdown. With that being said, what was your battery like before you started all of this? If it's below 50%, you're going to have a hard time. Shut the phone down and charge the battery ovenight, prior to attempting to fastboot.
If your battery is good, then you can fastboot. Hold all three buttons down, until you get the phone to power off. As soon as power goes off, you'll see a quick line flash at the top of the screen. As soon as you see this flash, quickly let go of the power button and then re-press it. If you got it right, you'll go into the fastboot menu. If you got it wrong, it will attempt to reboot. If it reboots, just try the button combo again. Once you get into the fastboot menu, use the vol- key to get to the option you need, and then hit the vol+ to choose that option.

I have done your steps and I get the menu up, but when I try to scroll down with the volume down button, it doesn't move. It just stays on "normal powerup". How can I fix this?

you have to time it correctly. Turn on the phone holding power and volume down. Then when the logo shows. Quickly (not too quickly) release two buttons and press them again and hold them until recovery factory reset screen appears then press two times power button to get into recovery.

Your bootloope, can you get into download mode? Try vol up and power. Then vol down to recovery....
Got a reply from the other thread:
Use this method (scroll down to where it says Master Reset with Hardware Keys). I ran into this issue a few times, and this is how I can get back into TWRP (when you follow the instructions, instead of wiping everything it boots into TWRP)
https://support.t-mobile.com/docs/DOC-7590 [start from "when LG Logo is displayed", since you can't power off]
(NB: It says T-mobile, but it works for all variants)
THIS WORKED!!!!!!!
Thanks again guys!

[Q] Please help! Stuck at LG Splash screen on boot

I am rooted and had PhilZ recovery installed on the vs980. I wiped data, cache, and davlik to install a new rom, but the install failed. After the install failed I realized I had deleted my backups I had. When I went to reboot the phone said it could not find root and would attempt to root on its own or something of that matter. I am now stuck on the lg spash screen with the led blinking green/blue. I cannot boot into recovery or download mode by holding the volume+power buttons the phone just vibrates and turns off for a sec then right back to the lg screen. Can someone please point me in the right direction. Thanks in advance
Yeah try booting into recovery but a little differently this time.. Turn the phone off, hold power and volume down to turn it on but keep holding it until it shuts off again. Then press power and volume down again until the LG logo appears. Release and press them again quickly like normal. This has worked for me in the past when I couldn't boot into recovery. Idk why but it did.. Give it a try

[Q] Bricked Verizon G2

I made the mistake of wiping TWRP from my phone. I did a factory reset when I booted into TWRP. I tried installing the camera app mod. I am on 4.4.2. I am currently stuck on the LG screen and the phone will not power down. I cannot boot into download mode or recovery. I have tried to research as much as I can from other threads and I cannot find any that match my issue. Do I need JTAG service to fix this?

While my phone is stuck on the LG screen (the phone will not power down) I hold the power button until it powers down, and it automatically reboots. When it reboots I hold the power button and the volume down button when the LG screen reappears and it just reboots again. Thanks for the quick reply. -Josh

Okay, Remove your battery and reinsert it.
Dont press the power button yet.
Now connect your device to a PC with HTC USB drivers installed and enter the following commands.
adb devices
adb reboot bootloader
If you are able to get into bootloader, let me know.

There!!!!
That's your problem.
When the phone is off and and u press volume up and power, it boots the device in safe mode.
Safe mode disables 3rd party apps at boot up.
Now this only works with stock ROMs and some custom sense ROMs.
If your ROM doesn't support this feature, it would boot into this black screen and begin to flash the red led.
So when the up key gets stuck or malfunctioned it causes the device to boot into that mode at start up.
But what I can rap my head around is why it won't boot into bootloader when you use adb.
