[Q] cant boot into bootloader from power off! - Nexus 4 Q&A, Help & Troubleshooting

I flashed a ROM boot looped and boot loader wouldn't work, volume down and power, but I got it to work via adb, anyways I still can't get into boot loader even after the fix? I'm just confused now, because if I boot loop again I'm going to have to do all that work over,
Someone care to provide an explanation and fix for this? Please and thank you lol!
Thanks josh

What I'm trying to say is that it just doesn't work, the bootloadrr will not boot unless done from reboot menu on ROM, holding buttons does nothing just keeps looping Google screen until I let go the boots normal, Lol I'm not a noon just confused that's all! Can I flash stock boot loader zip? Or will that brick me?

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] Nexus 10 bircked after fasboot unlock

Not really bricked I would say, But i did fastboot oem unlock and pressed unlock and start and it just stays at the bootanimation logo no matter what i do. I tried to flash the factory image back, it says completed but then it wont boot still, i tried to re lock the bootloader and nothing, any ideas on what to do?

Are you able to access recovery at all? If your able to access recovery try preforming a factory reset to see if you can get past the boot animation. Also check out this information that may be helpful.

Always glad to hear that I was able to help someone out, but I'm always especially happy when I can help someone un-brick there device.
so the deal here is...
so once your in bootloader, hit recovery, then you will see the little dead droid with the triangle... this is where it gets tricky...
keep tapping ( DONT HOLD) the power and volume left ( dunjno which is up or down, so i say left, the one close to the power key)., or in somke cases just mash all the buttons till the menu pops up! then click wipe data then wipe cache and the device reboots itself... give it a try!
i dont knwo why the recovery menu doesnt pop up unjtil u keep pressing volume up/down and power buttons, just keep tapping them in the recovery menu weith the android triangle and u should see the menu pop up

Very interesting to know, maybe you should make a thread in the general section with your findings so other people can easily find this useful information as this seems to be a common problem people run into.

Works perfect. Thanks so much... :laugh:
I've actually heard that it's a fastboot problem (with the tool, not the firmware on your device). Downloading the latest version of platform-tools solved this particular problem in a hurry for me, and it's probably best practice in the long run.
Is there something I can do in this situation except i don't have stock recovery installed?
Nevermind had a moment

[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

go to the last page new tools and utilities up from matt and it works just unbricked me be sure to thank him :good:

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.

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
I have a
Droid Razr M
Rooted, no custom Roms or Recovery.
Changed my build.prop from XT907 to XT1087
Changed My Boot Animation to R2D2

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!

P8 Screwed

So I had CM on my P8 before. I wanted to go back to stock, so I rebooted to fastboot and flashed stock recovery and also system.img. What I didn't realize was that I had flashed again the CM system img instead of stock. Now, phone is stuck on the bootanimation in CM and wont boot.
Trying to go to recovery just results in a black screen flash and then reboot to Huawei logo again. Holding the down volume button and powering up, or holding both up and down and powering up doesn't get me into bootloader/fastboot. Even before this the combo key never got me into fastboot.
What do I do?
Thank you.

It kept on rebooting from the black screen., maybe 4 times or more. I just persistently held the button combo till I got into fastboot.
