Non-rooted bootloop problem - Nexus 5X Q&A, Help & Troubleshooting

Just today, out of nowhere my phone restarted itself and got stuck in a bootloop. I tried to boot into recovery mode, but that wouldn't work either. Every now and then when I tried to go to recovery mode it would say "no command." Now the phone wont turn on at all. I am not rooted, so just running stock Nougat. Does anyone have any advice or links to tutorials that I can use?
Thanks in advance.

Sadly you're facing the bootloop of death which renders the device completely useless, no tutorial is gonna work for you to be able to fix it. You should send it to Google or LG if it's still under warranty to get a replacement.

Unfortunately sounds like an hardware issue, no tutorial can fix it.

Did you press and hold the "Power" and "Volume Up" Button after that "no command"? Then just release the Volume Up Button to access Stock Recovery.

I haven't. I'll give that a try assuming I can even get it to that point again haha.

I have the same problem, and now its completely die

[Q] a100 bricked (not rooted, can't recover)

Hi,
My sister has a acer a100 tablet for some time now, and suddenly it won't boot, it's just stuck on the acer logo. The device is not rooted.
I've tried just about everything I could find on the internets. When I go into stock recovery, an android with a red triangle appears together with some yellow text mostly saying it couldn't mount anything, after a while I get the recovery option, but am unable to select anything, I can toggle between them, but pressing the power button doesn't do anything.
I've also tried some fastboot tricks I found, but no luck.
I don't know if she was installing some firmware update and then shut it off (she says no), so I don't really know which android version she has.
I hope someone can help me figure this.
thanks in advance!

Take a look at the brick thread, sounds like a perfect example of the brick bug.

[Q] Can't boot to recovery or download mode

It is a long story, started with wanting Photoshare App. After rooting using Odin got into all sort of process stopped error. Desperate, downloaded and tried to flash CM10 using CWM. All I got was CM logo circling endlessly for 30 minutes. Pulled the plug and now, I seem to have a brick, can't even boot to recovery or download mode. When I try to boot to downlad mode, the warning screen appears for just a second and goes away. When I try recovery mode Samsumg log appears and then blank.
Is there anything I can do at this point? I appreciate any help I can get.

Hm. if you boot up your phone are you stuck at the cm bootup? If you are im sorry bro you cant fix it for free by sending it to samsung. JTAG for 60 bucks or samsung for 60 bucks. Reason being that it shows that you have rooted and modded your device. If you were hardbricked and nothing would turn on at all you would be able to send it to samsung and get it fixed for free!
Well if it shows Download mode then it might be working, just not showing, if you see a blue ID:COM number in Odin its working. Try to flash a stock ROM in Odin while in Download mode and make sure its in PDA or you will brick. Check only Auto-Reboot and F. Reset time.
If it works congrats if not search this forum for a service called JTAG which repairs bricks.

A little update ...
I was able to get to download mode after many trys and got back to stock -- unrooted. I should have stopped when I was ahead, but I was feeling invincible after this feat of reviving the phone and that was really stupid.
I wanted to root and flash CM10 nightly. I followed the instructions from http://rootzwiki.com/topic/32486-gu...m10-nightlies-without-k-exec-updated-8-18-12/. After unlocking the bootloader step, I wanted to backup the stock ROM I had on the phone -- I don't know why I wanted to do that as I had just flashed the stock and didn't have anything customized. Anyway, when I clicked backup from CWM everything died, kaput, nothing. I have been desperately holding the power button, reovery combination of buttons, download mode combination, anything I can think of, the phone is giving me the total silent treatment, which BTW I am used from a more human source.
Let me know if there is anything I can do, perhaps stand on one leg and try switching it on perhaps. http://forum.xda-developers.com/images/smilies/redface.gif
Sorry for the dumb jokes, I am a little frustrated, but I am sure I will get over it.
Thanks for those who took interest to read my question and those who cared to respond, I appreciate it....
Cheers!
are you getting any signs of life with the phone plugged in with or without the battery in?

Best advice...take out the battery, leave for 1-2 hours, insert battery, try to access download, flash stock in odin, reboot, don't flash any more Jelly Bean roms. lol

[Q] 'Secure boot Error!' at boot, download mode and factory reset don't work

Hello,
Here is what led to my issue:
I rooted my phone using this method: http://forum.xda-developers.com/showthread.php?p=38886073#post38886073
Downloaded clockwork rom manager.
Here comes the thing I don't remember. At least i know that the last thing i did was to click on 'backup current rom'
After this the phone reset itself and this message came up:
Secure booting error!
Cause: boot certification verify
Then i tried to reset using the power button, which led me to the 'battery full' screen - afterwards i was able to reboot. As stupid as I am I just tried the same thing again. And ever since i am stuck at the 'Secure booting error!' screen.
I am unable to enter download mode. I get to the 'Hard factory reset' screen, but if i accept doing so, it says 'Secure booting error!' again.
I also remember clicking on 'restart into recovery mode' at some point, but this is not the last thing i did.
I am really desperate. Please, help me!
Well i had the same issue today... It happened after i did two changes. One of them was to to try to relock from freegee and flash twrp again from freegee. In my case i was able to go in download mode and flash original kk rom with lg flash tool.
Unfortunatly, trying to boot in downloadmode, i still get the same error :/

How are you trying to boot into download mode? And what factory reset screen? It seems as though you did not unlock the bootloader using freegee, if you make any changes and relock the boot loader you will get that error. But it seems that it has not been unlocked. If you hold power and volume up what happens? Same thing when power and volume down, one of them is recovery (possibly factory reset you are seeing) and the other is download mode. I don't remember right now but you should read the whole softbrick thread and see if you are missing something. You may need to use LGPNST to go back to stock, you can also use that program to flash a new recovery so read carefully and follow all steps.
When this happened to me I was able to flash an unlocked bootloader and it allowed me to use my phone again as it was before doing something stupid (for me it was an attempt to re lock the bootloader).
well, i managed to get into download mode. Obviously i used the wrong method to get into download mode...
I used this method and everything worked fine, so far. : http://forum.xda-developers.com/showthread.php?t=2249500
My phone doesn't boot now. Fast Boot doesnt work aswell.
All that happens is a white battery showing on the screen and when i try to fastboot all that happens is that the LED is blinking or glowing red after some while.

What do you mean when you try to fastboot? Fastboot is basically the bootloader and allows you to select recovery or download mode. What you should have done after following that thread is go to recovery and wipe everything and flash a new ROM.
If you are saying that the bootloader is not coming up and allowing you into recovery then I believe something was missed.
After trying out some varioants of this it worked: http://forum.xda-developers.com/showthread.php?p=40274560&highlight=red+led#post40274560
I wiped the phone, but since I had to leave over the weekend i just turned it off and went away.
Now that I am back, nothing works now :/ The Phone doesnt react to anything, not even donwload-mode.
Is the battery too low maybe? It's on the wall now for a few hours, but it still doesn't react. It's not warm either.
edit:
when i charge the phone, i will get a 'watchdog bark' after some time allowing me to get into recovery. accesing downloadmode from there doesn't do anything. strangely, the recovery isnt trwp although it should be because teenybin comes with it. it's 'bbs.gaodi.net' which doesn't have a sideload feature. what do i do now?
edit2:
after 10000 tries i got into download mode. i don't want to **** up now so i won't do anything until i know exactly what to do.
any advice?
edit3:
got it working by flashing another teenybin which included trwp - then i installed miui via sideload. i don't have signal though, but i will open another thread for this since this is another issue.

How to fix blocked boot recovery samsung?

Hello guys,
A few months ago, I rooted my phone using kingroot. After a few weeks, i tried to install TWRP custom recover to unlock bootloader. I accidently downloaded a wrong version of it and flashed it using flashify app, after which i booted into recovery to check the new recover mode. But, something awkward happened. THE BOOT MODE DIDN'T OPEN AND THE SCREEN GOT STUCK AT "Booting into recovery". I read on the internet and realised that my device has got soft-bricked. Also, phone wasn't rebooting. So, i found a solution atleast start my phone. I took out my battery, pressed the buttons for download mode and then placed the battery back in and pressed the buttons for download mode and somewhow rebooted my phone (i read about this technique in xda forums). Now, although my phone works but i cannot access the recovery mode as it has got soft-bricked. Thus, i cannot perform a hard reset as it gets caught in that "recovery booting stuck cycle". So, can anyone tell me how to fix this? PLS QUICKLY. aLSO, i don't know much about ADB, so pls explain that too as my friend suggested me to use ADB to fix softbrick but im not sure!!

Galaxy A50 Stuck on Boot

here's what happened, the phone started freezing and restarting every 5 mins, I uninstalled some apps thinking that's what's causing it, I used it for around 10 minutes and it was fine, installed the latest security patch update, restarted and everything looked fine.
plugged it in, saw it had restarted again and it was stuck on the Samsung Galaxy A50 secured by Knox screen,
rn: I can't enter recovery mode, (the phone won't shut down and releasing the volume down and holding volume up thing doesn't work)
I can only enter download mode, Connected to Odin, flashed the latest firmware and it passed successfully, but still it gets stuck and won't boot.
any ideas?:crying:
anyone?

Volume up and power doesn't do anything
Volume down + power restarts the phone but it comes to the same samsung black screen
Are you sure you flashed correct firmware? Tried to factory reset in recovery? Full Wipe and then flash the firmware?
You can also try 'adb logcat' to see what the error is if adb is available..

I can't enter recovery mode
Volume down + power restarts but I did try to go to recovery by releasing volume down and pushing volume up the second screen goes black but it's not working
I can only enter download mode when it's connected to pc with odin running
Could it be a hard drive problem?
And I'm pretty sure i got the right firmware
Tbh not sure i got my A50 just recently, didn't even flash anything yet. Is you phone detected when you type "adb devices" in windows cmd?

tried it, it doesn't recognize the phone.
is there anyway to figure out if it's a hardware issue?
cuz I've heard it's a somewhat common problem in the A50 for the hard drive/storage to go corrupt.

I am having a very similar problem to yours, so I will follow this thread. I was using my phone two days ago and it simply turned itself off and since then I am stuck in the logo screen. When the phone is loading I have no indication whatsoever of the battery percentage at all. I still can access option and factory reset and wipe cache (unlike you, apparently - but it does nothing for me). This simply does not help. I end up back at the logo Samsung Galaxy A50 screen. I have downloaded two different firmware... android 9 and 10 from Samsung mobile, and have used Odin to flash it. The process goes through ok and without errors. I get the pass message and the message that the phone is being updated. Then it is time for the logo screen again and form then on the phone simply does not start. I am lost. Can anyone help?

hey there.
apart from the factory reset thing it seems like we have quite the same problem,
at this point I'm afraid it might be hardware thing

You know... I am not really sure. The only different thing I did was to accept to instal a new firmware one or two days prior. I am inclined to think that was it. Anyway... I tried to flash Android 10... Android 9 (both via Odin) and did not work. The support team instructed me to do the hard reset a couple of times ... and wipe cache and nothing. Today I sent my phone to Samsung assistance since it is still under the guarantee because that is what they thought I should do. I'll keep you posted. Hope you can get yours fixed soon.

yh I installed that update too and this happened later the same night.
unfortunately for me all the shops n services are currently shut down because of the Co-Vid situation so i have to wait for now.
thanks for sharing, lemme know what happens.
I've had these same problems before. When flashing with Odin, don't populate the last slot with anything (the HOME_CSC slot). Flash it to the device without auto reboot on, restart the device manually and hold vol up + down to get to blue scrern, then unlock bootloader. Let it restart, then reflash ROM.
