Help phone stuck at boot screen

Hello. I just tried to unlock the bootloader on on Verizon Galaxy nexus. Now it's stuck at the bootscreen with the lock image. I did a search and couldn't find a exact answer for my issue. I hope I haven't bricked my phone. Anyway, any help would be appreciated.
I wasn't trying to root just unlock the bootloader. It appeared everything went ok but, now I'm stuck. I used the same method for unlocking the bootloader on my GSM G-nex and it worked.
I know I've done something wrong or this may be something simple. I just need help so I can use my phone.

are you able to boot into the bootloader? if so you should be able to recover and can't worry a little less.

same thing here... I posted a request for a LTE boot.img since can still get into the bootloader

No I don't believe I can. When I type fastboot it just says "waiting on device" I can hold the volume down & power buttons and get to the screen were it says "start" at the top and below that "downloding"

Yea, that was what I was eluding too, The device just came out and google released the GSM image. I am sure that it will appear online in the near future.
if you are able to get into the bootloader does it say that its unlocked ? is your google splash screen showing the unlocked padlock ? you could also try fastboot flash recovery to get cwm on there and provide additional potential solutions.

Yeah, when I did the procedure it said that it was unlocked. Everything looked ok , it booted show the unlock symbol under Google. It then went to the colorful animation and was stuck there. At that time I pulled the battery and, it's been stuck at the screen showing google and the unlock image.

you should have let the animation run for like 10 minutes the phone has to rebuild the first boot can take like 15 minutes sometimes.
try booting into the bootloader see if that works still

Sorry I wasn't paying attention and didn't read the part were you told me how to get to the fastboot screen. I'm there now. Can I just relock or fix the bootloader from problem there? It shows it unlocked at the fastboot screen.

you could try fastboot oem lock and see if that works but if the phone wasn't booting i don't know if that will fix it but worth a shot.
try it out and see. it shouldn't do any harm to try

I had the issue with the failure to boot up after doing the fastboot oem unlock (I had to use the pda net drivers to get my device recognized to get even that far). I did a lot of things like pulling the battery, locking again and then unlocking and nothing worked until I went here http://rootzwiki.com/topic/11732-galaxy-nexus-root-procedure-adb-method/, then downloaded the files following their directions and doing the fastboot boot boot.img command. It took a LONG time to boot up, but it did boot finally.

Thank you, I'll try that.

I have another question. One of the selections on the fastboot screen is recovery mode. Can I try that or is this something were you have to have a rom stored on a sd-card?

you could download the recovery image from
http://forum.xda-developers.com/showthread.php?t=1392336
then when connected in fast boot flash it with
fastboot flash recovery recovery.img
(rename the file from the linked thread to recovery.img)
this should write your custom recovery partition.
once you have that though you are still not going to be able to boot but it would allow you to flash a nandroid backup if someone made one for you or a LTE based rom
EDIT: you could also try a factory data reset and wipe dalvk cache from withing cwm. that may fix your boot problem

I had this problem, too.
I downloaded Clockwork Recovery and used 'fastboot boot LTErecovery_cwr.img' to boot into it, I wiped data and cache / factory reset and then rebooted. It rebooted twice, but after ten minutes or so I was back to the ICS Welcome screen. All of the files I'd put on my internal storage were wiped (during the oem unlock, I assume) but I'm in the stock rom but Superuser was installed and I have root access.
Hope it helps.
EDIT: looks like this is the same thing Goat_For_Sale posted above, but his command flashes CWM where mine temporarily boots into it. Since most of us will be installing CWM anyway I'd recommend using his command instead.

Ahh no problem.
I got pretty worried for a second that I'd already broke my shiny new Nexus, so I'm really hoping I can help out someone else that had the same problem.

Solved
I believe it's fixed now. I use the method that GirLuvsDroid posted from the Rootzwiki forum. Once it rebooted, I stopped there and didn't root the phone. I was just happy to get it booted.
It's downloading all my apps and settings now. Thanks to everyone who tried to help me, I really appreciate. This was a good learning experience for me.

So you were just able to go through the Rootzwiki method? Were you stuck at "Downloading...Do not turn off target !!" screen when you went to boot screen originally? My device still can't be detected :/

Help!!!! Bricked one m9! No fastboot commands, no adb, just a blue screen!

Please help urgently! So I just S-OFF'd my phone (right after unlocking my bootloader via htcdev) and I was excited to finally manually flash a 5.1 update to my EE UK One m9. I sort of made it a European version by changing one of its update numbers to [BLANK].401.[BLANK]. I then spent the whole night booting my phone into download mode and using fastboot commands: "htc_fastboot flash zip...".
Each zip was the previous update to the other, I.e. I was already on 1.32.401.6, so I used fastboot to get to 1.32.401.8 as the cmd. prompt said that it was successfully installed on my phone (p.s. I didn't have an sd card big enough to exfat 32 and put the update zips on it). I then repeated the steps again, but then fastboot flashed "2.10.401.", this was the update that would hopefully bring my phone to 5.1 . The cmd. prompt said that it was a success so I booted my phone up as normal, but I went to the settings to check software information and it was still on 1.32.401.6! It then said an update was ready to install so I just installed it as normal. Once it went into the bootloader it flashed it without any problems and tried to boot back up again. It then lit up a blue screen for 10 seconds and then went into the black HTC RUU screen with the grey htc logo. My phone has now, for the last hour, been stuck in this infinite loop of blue screen, vibrate, ruu screen and REPEAT. I've tried pressing vol. down and power as well as up to get into other modes like download mode, but it doesn't work. I CAN'T EVEN TURN IT OFF! I HAVE TO WAIT FOR IT TO RUN OUT OF BATTERY! MORE IMPORTANTLY, ADB DOESNT RECOGNISE IT, NOR DOES FASTBOOT!!!! SO I CAN'T EVEN FLASH A STOCK RECOVERY, SYSTEM IMG, ETC! PLEASE IF ANYONE CAN, HELP ME. I REALLY DON'T WANT TO HAVE TO BUY A NEW ONE AND PAY S-OFF AGAIN!

what you should do is if you can restore a backup, put a 5.1 rom on your sd card and after you flash the latest firmware 2.10.401.xx. then boot to recovery and install the 5.1 rom.

well, that's the sh^ts, I don't know at this point.maybe someone else can chime in here that can help.

I've seen this before, and there is no fix that I'm aware of. You've corrupted something important in your firmware, probably by flashing all those firmware packages.
You made several mistakes here, the first in thinking you needed to flash every firmware for your phone. All you needed was the last one. The other mistake was confusing your OS version with your firmware version. You were still on 1.32 base but your firmware was updated.
The last mistake, and the one that probably did the damage, was trying to take an OTA after all that. You were stock enough for it to run, but since your firmware was already updated, the OTA broke something.
As far as I know, the only thing you can do is return it to HTC for service.

Uh Oh protection isn't available in the UK.
As you unlocked your bootloader and got S-OFF, they will almost certainly charge you for repairs as this isn't a hardware issue and was actually caused by you flashing your phone.

I'm able to enter the boot loader menu (with the options to reboot, power down, download mode and bootloader). Unfortunately, clicking any of the options (apart from power down) causes the blue screen boot loop to continue.

You said before that fastboot wasn't working. It's working now? Does it show up in fastboot devices?
If so, you might try running a RUU from bootloader.

The trixk is to flash and just after reboot press power and down vol to wnter immediatly into rexovery twrp just as it says in the link...just do it and will go into twrp once you have entered justflash any nandroid or flash a zip ruu from sd card in a sexond boot

I'm not able to enter RUU mode...

HTC One m8 doesn't boot

So I recently got a European M8 and thought I would root it which turned out to be a bad idea. To start off with, it didn't root properly anyway so i carried on using it. Today I wanted to recover it back to stock (When I got it out of the box) I did a command using fastboot which was along the lines of fastboot boot boot.img but now my HTC will launch the screen displaying that it is a build for development purposes only and then it goes to a black screen but still turned on. It seems to me like there is no Operating System for the phone to boot from.
PLEASE HELP ME
Issue Solved - 22/01/16

Hard to help, if we don't know exactly what you did. Try to explain in detail (or as best you can) the exact steps (including file names, version numbers, etc.) of what you performed.

Again, hard to tell what the issue is, if we don't know exactly what you did.
Are you sure you didn't do fastboot flash? I don't think you would do anything permanent with the command fastboot boot.
What exactly were you trying to boot/flash with this command? What was the file name, where did you get it from, and what was the exact intent?
Did you get this idea from a thread or guide?

If you hold power + vol up for a long time (30 seconds or more) does the phone reboot? Then what, black screen again?
Do Power + vol up again. The moment the screen goes dark (but before the HTC logo screen with the red text warning) let go of those buttons, and only hold power down; and don't let go until you see the bootloader screen. If this fails, try again, you probably just got the timing wrong (started pressing vol down too late, or let go of it too early).
Once in bootloader, select fastboot (if not in that mode already) using vol keys, then confirm with power button. Connect to computer and do: fastboot getvar all
Post the getvar output (delete IMEI and serial numbers before you post).

Again, i am really sorry but i do not understand what i did. It asked me to flash the ROM Update Utility and then use fastboot boot boot.img which then screwed it up and yes when i boot up and reboot it just goes to a black screen.
Here is the info:

I seriously doubt that you can't remember any of the steps you did to try to root it.
Just sounds like you are too lazy to type. So why should I put forth more effort than you; when you are the one that wants help?

Do you have a file in your fastboot folder (wherever fastboot.exe is located) what is actually named boot.img?
And you really can't remember if you got this idea from a thread? You had to come up with it somehow.
What were you even trying to do here? What did you think the command would do?
Again, either you are just being lazy, evasive, or got hit on the head to cause amnesia; if you can't answer the questions.

So I was looking for tutorials on how to root it and I cam across a program (cannot remember the name) which was designed to root it with a few clicks of buttons ect. I already new how to unlock the boot-loader because I owned a HTC desire 510. I went back onto my phone it has twrp installed but I use root checker and it says that proper root access is not granted and I have tried to use SuperSU but I got the binary issue so I gave up. It was working fine but today I decided I wanted to revert it back to stock again but did something which completely messed it up.
Also, i decided i wanted to restore it because if it broke and i needed it to be repaired it would void my warranty. I was thinking when i reset the RUU it would make it stock again but it did not.

Now, that's more like it!

An Android app, or PC program?
Either way, one-click type root apps don't work on HTC devices. PC based toolkits worked at one time, but were never updated to support the recent software builds (outdated TWRP versions fail on Lollipop, and outdated SuperSU versions fail).

What did you think you were doing with the fastboot command (fastboot boot boot.img)?
One thing I can say for sure: Don't try mods, fastboot commands, etc. unless you know exactly what you are doing (such as following reputable instructions to the letter). The command you did just isn't right. You either got it from a bad source, or you decided to improvise or experiment (really bad idea). You made the issue much worse than it was to begin with (probably just needed to flash the updated SuperSU zip, maybe also update TWRP).

Fastboot boot means you are trying to remote boot something without flashing it. A boot.img isn't bootable. I've only seen this done with recovery.img
I think you meant to do: fastboot flash boot boot.img
The one different word makes a huge difference. The action is to flash, not boot. The "boot" is the location of where to flash to.
Also, even if you properly flashed boot.img, this is just the kernel, and wouldn't change much. To return to stock, you want to flash a full ROM. And kernel, ROM and firmware are not interchangeable terms, so don't for a second think they are.

Ok. Is it possible though to revert it back to stock and if yes, do you think you can help me?

Do the fastboot command: fastboot oem lock. Then download the 4.16.401.10 RUU from the following thread, and run it from PC: http://forum.xda-developers.com/showthread.php?t=2701376
Your alternative is to restore the proper stock TWRP backup. While the relevant files are on that same link, you'll find clearer instruction on the following thread: http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860

The security warning just means you altered something in the stock software (root, kernel, etc.). It doesn't matter, as the RUU will write all partitions to factory condition.

What does your PC screen say? Is the RUU stuck sending?
You probably just need to disconnect the phone and start again. RUU just gets stuck sometimes. It shouldn't take any more than 5 or 10 minutes.

My HTC M8 Stuck at ONE Logo once restarted. No Recovery, No DWNLD mode available.

I've seen already this thread suggested by XDA thread locator.
https://forum.xda-developers.com/htc-one-m8/help/verizon-htc-one-m8-stuck-htc-logo-t3163088
But I'd try to explain as simple as possible the whole situation which happened hours ago.
Don't know what happened but my mothers phone went off and restarted with htc one logo on it and nothing else later.
Power button itself doesnt work and is not responding.
Configuration PWR + VOL UP gives me restart but no recovery mode, giving me sound effect of restarting phone and ONE logo on it without any other reaction whatsoever.
PWR + VOL DWN zero reaction
PWR + VOL UP & DOWN pressed together restarting the phone and then gives me HTC ONE LOGO and nothing else.
when Phone is plugged in to the computer and I'm forcing the phone to restart it shows me new Device on the computer as a CD Driver every time.
So I think there is still hope to get this guy back to life.
It's running on custom rom but unknown version because it was purchased as a refurb from ebay 2 years ago and it was running just fine utill this very day.
I'm absolutely noob with flashing twrping etc so please ELI5 if possible, any type of help will be much appreciated.
Thanks in advance.

Hey, I had this same problem a couple of days ago. Here's what I did to get the phone into fastboot, from where you can install a recovery, factory reset etc.
1. Hold the power button + vol up button for about 10-20 seconds. This should shut down the phone.
2. Hold the power button + vol down button to restart the phone back into fastboot.
If you can get into fastboot, there are plenty of guides which can help you flash a twrp image. If you want me to give you some instructions on that just reply and let me know. Good luck!

Note that this phone doesn't have download mode (as some other Android devices do); nor is there a button combo to go directly to recovery. But you can almost certainly still get to bootloader, and from there boot recovery. In the current condition, you can get to bootloader by:
1) Hold Power+ vol up (as you have been) to restart the phone.
2) Once the screen goes dark (signaling it is about to reboot) let go of the buttons, and only hold vol down
3) Don't let go of vol down until the bootloader screen appears.
4) If the above sequence fails, its virtually always because the user just didn't get the timing right (either started pressing vol down too late, or let go too early). Just repeat steps 1-3 until you get to bootloader.
Once in bootloader, try to reflash the ROM, or restore a TWRP backup (if you have one). Spontaneously stuck on HTC logo screen is often a result of the OS/ROM becoming corrupt or otherwise damaged, and flashing/restoring the ROM will often fix it.

Thanks @redpoint73 I've managed to get to the preinstalled recovery.
Sadly reflashing/factory reset failed few times due corrupted files.
I'm ok with the fact that I lost the data on the phone since most of it was stored on the cloud.
Now I need ROM to flash on the phone thru recovery but I don't know which one would you reccomend.
It's my mom's phone so basically reliabilty and robustness over flashing lights and numerous unnecessary functions.
Version of android doesn't really matter.
Thanks again for help so far.
Can I put the rom I'm about to flash on external SD Card or I have to transfer it thru computer to the phone?
TWRP might be extra helpful or the recovery it's functions are just fine?

I'd need to know more about the phone in order to give any suggestions.
With the phone connected to computer, boot into fastboot mode, and (assuming you have fastboot setup on your computer) do the command: fastboot getvar all
Then post the results (delete IMEI and serial number before posting).
Also, what version TWRP (if that is the recovery installed)?

You will be able to flash a ROM from the SD card, if using TWRP.

Not sure what is being asked here (can't quite understand). Are you saying that another recovery besides TWRP is presently installed?

@redpoint73 I don't have TWRP but this...
Maybe pictures will justify the real situation.
I don't have the fastboot preinstalled on computer. (yet)
I wouldn't mind link to the pack with "must have" to complete the process

You have what is called the "stock recovery" or official HTC recovery.
You can't flash anything but OTA updates, or other official (HTC) signed zips with this. You need a "custom" recovery like TWRP in order to flash things like custom ROMs. So I'm curious what you meant before when you posted:

What exactly were you trying to "reflash", what were the exact steps, and the results (specific error messages, etc.).

I did the factory reset but it didn't help still stucking at ONE logo like posted initially. So this is basically the situation right now. I was able to get to recovery but nothing else.

Okay, so you're confusing the terms. Factory reset doesn't flash/reflash anything (flash meaning to install some firmware or software to the device). The only thing that factory reset does is wipe user data.
At this point, I'd suggest the best/easiest course of action in the current conditions (stock recovery, locked bootloader) would be to run the RUU intended for your device. Your device is the AT&T version, so the RUU can be found at the bottom of the page (and instructions on how to install): http://www.htc.com/us/support/htc-one-m8-att/news/
RUU is a complete factory image. You download to a PC (PC required, won't work on Mac or Linux) connect the phone (booted into bootloader-fastboot mode) then just run the RUU, and it will do the rest.
I'm confidant this will get the phone up and running. Your mom may not like all the AT&T branding and apps, if it wasn't there before, and AT&T is not her carrier (one of the main reasons for these devices to have custom ROM - to remove carrier branding). But we can cross that bridge (if need be), after we get the phone working.

Installed Software, downloaded RUU from website provided, turned phone into fastboot before installing RUU.
Something started happening with the phone during installation but installation itself cant be finished, it's an endless process of update, phone is already plugged 3rd hour or so to the computer but the update status remain the same.
Should I try different approach?

It just gets stuck sometimes. Just kill the process, and start the RUU again. It will probably work fine on the next try. It's a bit scary, as it says not to stop the process or disconnect the phone while it's running. But if it gets stuck like this, there isn't anything else you can do.

Good News, it's working. But it's bloated to the bones. How I can get rid of the carrier unnecessary software?
I was to afraid to kill the process during update to avoid scenario of bricking my phone completely.
But It's working!

Htc 10 stuck in bootloop-

Hi, I bought my HTC 10 around 7 months ago and a few weeks ago it restarted and it´s kept restarting since then. I tried doing a hard reset from the recovery because it doesn´t boot properly, but it didn´t work. I wanted to flash the RUU but I couldn´t find the right one on HTC SUPPORT. I wanted to try rooting my device and wiping data using TWRP to install a ROM and see if this could work, but as my phone doesn´t boot, I can´t unlock the OEM or debug developer mode.
Now I can´t even access to recovery mode so I can´t check my OS model, I just can access to bootloader mode.
If anyone can help me I´d really appreciate it.

Did your device still S-ON?

If you didn't do anything to your phone it's probably the battery. This is the most talked about problem in these forums. Can you boot to download mode? If so what's your CID?

I just wanted to try to fix my phone. It´d be really great if I can fix it by myself but know I´m not sure if I can do it.
If I can boot to download mode I´m gonna try to flash the RUU, but I couldn´t find the right one because my phone was made in United Emirates as HTC support told me

You need to flash ruu in download mode. What was wrong with your phone to begin with? Also what have you done? You can't just say I was trying to fix myphone and expect us to know what you have done. You need to provide more details

My phone is in a stuck in a bootloop, I was using it one day and it restarted by itself. I was able to use it for a few minutes and then it restarted again untill the point that it doesn´t boot anymore. The only thing I have done is a hard reset from recovery, but it keeps restarting. Now I can´t boot to download mode that´s why I haven´t flashed the RUU, I just can boot into bootloader mode and when I try to boot into recovery or download mode from there it restarts again.

im having the same issue.
the buttons randomly stopped working, so i restarted the phone only to be greeted with a bootloop.
i had lineage os on my phone for a while, and today i installed a update, so that might be related to the sudden bootloop.
when i press vol down + power it just boot loops. if i press vol up + vol down it boots into the bootloader.
trying to start download or recovery mode just gets me into a boot loop again.
the bootloader says s-on.
i just found this in another thread

Unbelievable - I actually managed to unbrick my HTC 10!! :victory::victory::victory: I still don't understand exactly what happened, but I'll document everything I did...
Before:
S-ON
Flashed bad boot image in download mode
Could not enter download, RUU, recovery, or system mode - all of them enter into bootloop
Could only enter white background bootloader mode (Volume Up + Volume Down + Power), which only allows flashing signed hosd image
What I did:
Followed @Tarima's link above. With the phone in the white background bootloader mode, I ran fastboot flash $x $x.img with $x = each of the partitions. Except for hosd, all the other commands printed an error like
Code:
sending 'xbl' (1809 KB)... OKAY
writing 'xbl'... FAILED (remote: cannot flash this partition in s-on state)
but I continued anyway.
Selected "REBOOT TO BOOTLOADER" from white background bootloader
Downloaded an RUU exe file from here (I got the 1.96.617.20 version, but in hindsight it probably doesn't matter which version), and extracted an RUU zip file (following this guide on Linux)
Renamed the RUU ZIP to 2PS6IMG.zip, copied it to the root of an empty FAT32-formatted microSD card, and inserted the card into the HTC 10 (inspired by this post and this post)
Selected "BOOT TO DOWNLOAD MODE" from white background bootloader
This triggered a screen prompting whether to install update from SD card (photo).
I didn't need to actually install the update from the SD card; instead, the presence of a valid update on the SD card may have short-circuited whatever was causing the download mode to crash loop, and allowed the phone to enter download mode and accept fastboot flash commands. Since my problem was a bad boot image, I just did
Code:
fastboot flash boot boot.img
with the boot.img extracted from the official Nougat OTA zip's firmware.zip, and it worked! Phone was able to boot back into system / download / RUU / recovery. :victory:
I'd already given up hope and bought another HTC 10 off Swappa I've now learned my lesson and I'm going to S-OFF at once.

i havent had a chance to try this yet since i dont have a usb-c cable on my hands right now, but i feel like it is worth a shot @MatiasCinic.
also here is a safe place to download the htc 10 ruu https://www.htc.com/us/support/rom-downloads.html
im gonna update once i tried it

I´m gonna give it a try, but I´m not sure if it´s gonna work. Hopefully I might be able to boot into download mode and get to know my CID. Thanks

i promised to update once i tested the methode. sadly it didnt seem to work for me.
flashing hosd worked like in jichuan89 case. but puting the 2PS6IMG.zip into a formatted sd card didnt seem to work for me.
booting into download mode sill gives me a bootloop.
unless someone comes up with a new idea on how to fix this, i might have to get a new phone :/

That's all good but unfortunately if you can't boot to download mode you can't flash RUU. Also if the method above didn't work i think it's time to send it to HTC or but a new phine

Alright, thanks for your help

Hi Guys,
I think the problem causes by power and volume keys' ribbon. When i try pressing and holding power and volume down keys the gray HTC logo appears. But when i try pressing only volume down key the gray HTC logo appears again. As if power button always pressing itself. I'm gonna try remove connection after normal HTC logo disappears. If it fix the problem i will inform you again. Wish me luck :fingers-crossed::fingers-crossed:

Unfortunately i buried my htc 10 with a ceremony :laugh:

I have exactly the same problem. Word by word of what is described here. I feel no linger alone ahah.
So I have two questions.You basically just copy de zip file named accordingly into an SD card and follow the steps? Can I do this on a Mac?
