[Q] Can't reboot system without going through fast boot.

Like the title says, my Nexus 5 won't boot unless I manually plug it in, hold down volume buttons and power, then wait 15 seconds for fast boot to appear, and then select "start."
Thats the problem. Now for some more information:
1. Nexus 5 32 gb
2. ROM: CM 11 Dec 13s Nightly
3. Kernel: Bricked 3.4.0
4. The phone is totally functional. The only thing wrong with it is that it can't reboot. From the system, TWRP recover, or anything, it simply will not reboot. Every time I must go into fast boot then press the power button when it says "start." After this, the phone works just as I would expect it to. I can still flash kernels and backups through recovery, it just must be restarted manually through the fast boot. This is a problem for me because I don't always want to have to plug it in when I want to reboot it.
When did it start:
Let me start off by saying that I thing the root of all my problems was the TouchControl app that allows the knock to wake function to work. I downloaded the app and was told to install the developers custom kernel. I did and not only did the app not work, it also seemed to brick my phone. I was scared, but, after doing some research, I found the method of plugging it in and holding down all buttons for about 15 seconds and my phone was saved. Ever since then there has been the problem. I must always do this to reboot my phone. Since the app didn't work I decided to install the Bricked Kernel and everything went fine except that I wasn't prompted with the interactive installer. The kernel works fine and I am now using the Knock to wake feature built into the kernel and am very happy.
Seems to be caused by swipe2wake aka knock 2 wake aka knock knock (but not totally sure)
What I've Tried (don't assume I've tried something I haven't. I could have missed something obvious.):
1. Resetting permissions through TWRP (just thought I'd try)
2. Putting back CM 11 Kernel
3. Restoring to a time when my phone did restart
Any help would be greatly appreciated. I will try to keep the original post updated with everything I try.
FIXED with the help of jd1639 and meangreenie
------------------------------------------------------------------
1.Follow jd1639's link in 3rd comment to the page and
A. Install adb and flashboot drivers
B. Install your version of factory images from google (if you are running 4.4.2 get the image for 4.4.2)
2. Plug in phone to AC CHARGER and hold down power and volume buttons for up to 20 seconds. This should put it into fast boot mode
3. After getting phone in fast boot mode, plug it into your mac or pc.
4. Out of all the instructions in the "How to flash a factory image" thread go to method 2 and ONLY DO THE FIRST TWO LINES OF CODE. All that needs to be flashed is the bootloader.img
5. After it says complete and your phone restarts you should be able to push "start" on your phone and be good!

I would try and fastboot flash boot boot.img. where boot.img is the boot image from the factory image.

So that's essentially flashing the stock ROM?

No just the boot.img
Edit, look at method #2 but only flash the boot.img nothing else http://forum.xda-developers.com/showthread.php?p=47156064

Thanks so much for trying to help. I installed all the things and flashed Boot.img from fast boot, but once I restarted my phone everything was messed up (booted to home screen but basically the system started failing). After this, I retried but deleted my cache and delvik cache. This time the system simply wouldn't boot. Luckily I backed up and restored to my previous version. Thanks for trying, but this did not work.

Were you on 4.4 or 4.4.2. Sounds like 4.4.2. The factory image in the link was 4.4

try reflashing via custom recovery or fastboot.. bootloader, recovery and suitable boot.img for your rom, maybe give the radio a reflash too

no it won't delete your data.. but please triple check your files and fastboot commands before executing
the last resort is to format data if all else fails

Thank you both so much. I have (with both of your help fixed it). I will post how in the original post. Thanks again.

[Q] Bricked Nexus 5

Hello
I followed this guide http://forum.xda-developers.com/show....php?t=2507905 to root my new Nexus 5 and flashed this rom http://forum.xda-developers.com/show....php?t=2528265 onto it, when I tried to boot it up it got stuck in the boot animation so I rebooted into recovery and wiped the data, cache partition and the dalvik cache and tried to boot it up and encountered the same problem so I went to reboot and it wont boot back up not even to the bootloader and when I plug it into my pc its unrecognized and wont even show charging animations
Did I brick my new phone?

Then it is bricked , but I don't really understand how could fromating data, cache and dalvik cache destroy the bootloader . There must be something wrong those recoveries, because you are not the only one

Did you ever check the md5 of the rom you flashed? It could have been a corrupted download

does your bootloader work? hold the vol up/down and power on boot. if u can get to the bootloader u can save it with wugs nexus tool.

If you can get into bootloader you can save it without a tool kit.

Do this if u can't go into recovery
http://forum.xda-developers.com/showthread.php?t=2513937
But if u are able to go into recover, just flash any other rom, make sure you before flashing u do a factory data reset, and after finished wipe cache/dalvik always so u dont go into bootloops.

Through some miracle I was able to get to the bootloader (sat there and held the vol and power buttons for like 3 minutes while my pc dinged and donged as it disconnected and reconnected) but I'm unsure of what to do now. Should I keep trying to load a custom rom on it or just go back to stock? and either or how am I going to get the rom on the internal storage as its still not being recognized by my pc (but I do have fast boot access)

Stay away from tool kits. You got enough problems on your hand

Glad to hear you're back up and running. Google md5 checksum and make sure the roms you download are good. I think that was your problem

Done this to my Nexus 7.. something went wrong when flashing the Rom and ended up somehow cocking up my drivers aswell.. Weird one.
Glad to hear your back up and running buddy.

Shield doesnt boot anymore

So guys, i've done it. I bring my first device.
Yesterday i tried to downgrade via fastboot with this recovery images https://developer.nvidia.com/gameworksdownload (yes is choose the right ones)
flash boot, check
flash recovery, check
flash system, failes (insufficient memory)
erase sytem, check
flash system, failed (insufficient memory)
flash twrp, check, but no usb mouse so
flash cwm, check
factory reset, check
rom.zip and gapps on sd card, check
reboot, boot into bootloader, no chance
It boots everytime normal, so i cant enter the recovery.
Connect it to charger, check
charging led lights up, check
Go sleeping, check
doenst boot into bootloader :/
Back to charger
Now I wanted to try it again and i wont even boot.
Anyone has an Idea? Or is it really bricked?

Can you still see the device listed using fast boot?

No, because I can't enter the bootloader or the recovery. But it boots again
...

The same thing just happened to me. Unfortunately, I am still trying to figure it out. I flashed a "stock" recovery that I had found in order to be able to take the OTAs. Now when I boot, I just stay stuck on the NVIDIA splash screen.....been there for hours.

Same here.....

Mine is working again. Booting in the bootloader is a little bit tricky.
Have you tried to flash all? Boot.img, recovery.img and system.img?
...

I had the same issue. But after trying to get into the bootloader using POWER + VOLUME DOWN for about 15 minutes it finally went to the bootloader and I was able to re-flash it. I have a feeling it's the cludgy power button.

You do not need to flash the stock recovery to take the ota. I have taken 2 otas now on custom recovery without any issue and without loosing root. Just an FYI.

I just did a factory reset under lollipop, locked boot-loader rooted and it rebooted to the green android screen then dropped into CWM and asked to fix root. I said no, then it went to the nvidia boot logo and it is stuck. Any suggestions? Thanks.
Edit: nevermind, I just powered it off after about 20 minuets and it hung again. When I plugged it into my pc, it finally poped into the setup/welcome screen. Pretty weird. Heart attack averted

stuck in loop, possibly a different kind of loop

I was trying to fix my girlfriends nexus 5 that was doing the restart loop after an update. Everything seemed to go fine. Unlocked the bootloader, etc. Flashed the newest rom (6.0.1 (MMB29S) ce1d670f61061c3902f3997510ea55d7 6bfcdfa4f4840898e5d76fa044f5e6a0f71343bf) and then something obviously went wrong (not quite sure, dont think i touched anything) and it's now stuck in a different kind of loop that only loops while it's plugged in. Ive uploaded a video to youtube, but since im a new user i cant actually link it properly yet. Hopefully this wont annoy any mods, I promise it's not spam. youtube . be / yNSoiTPnGZw
Is there any way to get it to stay on for more than a couple seconds to retry the flashing?
Any help is appreciated.

First i followed the guide here on xda to unlock the bootloader(guide-nexus-5-how-to-unlock-bootloader-t2507905), installed twrp, which went fine. Then i realized that i couldnt (or didnt realize how to via command line) to copy the stock rom and install it via twrp, so then i followed this guide here on xda (tutorial-how-to-flash-factory-image-t2513701) with the factory img (6.01 hammerhead), got to this point in the guide: ★After everything finished, select "Recovery" using the volume buttons. then it stalled out,turned off and now just cycles on and offf through the google logo with the lock picture or if i hold down the volume button it will go into the bootloader briefly then restart, rinse repeat.

Have u tried messing with the power button, there are a lot of issues on the nexus 5 with the power button causing loops, simply from getting stuck, try playing with the power button a little and see of that helps, it might just need to be replaced
Wait, did u flash the factory img with twrp, or did u flash it using fastboot?

in the end fastboot, since i coulndt see how i could copy the img over to install via twrp
im pretty sure the button is fine, since it was cycling from the ota update install, then was working fine unlocking the bootloader, but after the flash, it crapped the bed.

Different problem
I had a problem where the google logo keeps on booting up with a slight vibration.This started to happen when my was dropped.I initially thought that was a software issue and thought of installing new ROM's but eventually my device was not detected :crying:
So i took it to repair shop near my house and they said it would cost 2500
I did some google research and found the reason was due to the power button being stucked during the fall.I got that repaired and my device is good to go

ok, took it into a shop, got the power button fixed. It must have been on the way out because literally one minute it worked and the second it didnt. now i think ive got it narrowed down. it's saying it's unable to mount /persist. ive tried the various fixes:
e2fsck/dev/block/platform/msm_sdcc.1/by-name/persist
and
make_ext4fs/dev/block/platform/msm_sdcc.1/by-name/persist
but all i get is a not found error. not sure what to do from here on.

success!! i ended up stumbling on a bit how to restore the persist partition i didnt try. got a custom rom installs and everything works. thanks to everyone who tried to help!!

stuck in bootloop while flashing cataclysm rom
i tried to flash cataclysm rom in my n5..i unlock bootloader, flash custom recovery using TWRP and flash cataclysm rom following the instructions in this thread http://forum.xda-developers.com/goo...s-5-how-to-unlock-bootloader-t2507905...after that it was stuck in bootloop...i tried to open recovery but it wont open anymore it will only go back to loop....how can open the recovery? is it safe to flash CWM recovery?..tnx in advance..

When it was stuck in the loop, I had to hold vol up and down with the power button (wait a few secs until it was completely off) then reboot holding down + power till it opened the bootloader. if that doesnt work, try reflashing the bootloader via fastboot. I only found out i couldnt mount the persist partition by looking at the terminal window in twrp after trying to install a rom which kept it in the boot loop. I then used the cmd: make_ext4fs /dev/block/platform/msm_sdcc.1/by-name/persist to rebuild it.

After flashing TWRP, use the volume and power button to select recovery. Once in TWRP, wipe cache, data, reboot.

Power & vol down no longer loads bootloader after flashing

Hello,
I am getting myself deeper into trouble working on this.
First I will explain what I did, I wanted marshmallow and read TWRP needs to be updated to load it and also that that I cannot restore from older backup, so I figured I update TWRP first then do a backup.
I did the TWRP update via app, verified the partition and when done and rebooted to recovery, TWRP was still v2.7 and the phone won't boot, the OS was gone.
so then I figured I flash Dottat M8firmwareandRecovery to get the new TWRP and backed up the Data partition.
then found out that I can't use that Data partition with a different OS. So I figured I flash KitKat back on.
did that, now I can not get back into recovery, holding the Vol down with power will not go to HBOOT.
now KitKat loads, had root, but the dang thing auto updated to 4.4.3 and now lost root. I thought it can't auto update with s-off
so it as asking for another update now and I turned it off. Waiting for someone to help , I keep making it worse.
my phone was unlocked and s-off, I hope it still is, can anything undo that?
Please help

I've personally never seen a device go back to S-ON without the user doing it with the cmd.
That isn't to say it's never happened before.
I'd assume you are still S-OFF.
What happens when you flash a ROM that has a power menu and you select to reboot to recovery or bootloader?
Or you can root and download an app that works the same way. curious what it does.
Also how long are you holding the buttons?
If everything else is working you should be able to get to hboot/recovery - but I honestly don't know.
My suggestion?
Get a more recent RUU .exe and run it on your PC and see what happens.

My Galaxy Tab2 did that. I tried the M8 again today with USB unplugged, did not get boot loader menu, but then while it was on, I did a Vol up and power (forced shutdown) then while still holding the power button switched to Vol down right when the screen blanked, then I got the boot loader! :victory:

and to correct myself.. one other condition. The older version of software included a "fastboot" option in settings->power that was more like a hibernate feature. That feature when enabled would prevent you from getting into bootloader.

That makes sense, 'fastboot' was on, its now off.
The bootloader works, KitKat OS is working, but not recovery. I get 'Entering Recovery . . .' on white htc screen and stuck there.
I used adb command prompt to flash recovery with fastboot then I tried HTC_fastboot and different versions of TWRP.
tried flashing with Flashify , no errors, it just doesn't load. I think something else is broke.
dottat, do you have an image of RUU rooted Kitkat with TWRP?
Thank you for the help.

Your firmware is too old. That's why the newer recovery won't work. Do you want to update everything first and then RE-root?

Yup , that was it, the older one worked.
So dumped the idea of getting KitKat back and I flashed the Marshmallow custom s-off RUU with TWRP that you provided. so far good now I just need to re-root it.
Thank you
