[Q] [Help] Stuck in boot on Google

Alright. This is a 100% stock Nexus S- nothing "development" wise was done to the device, no system tools installed that could cause issues, basically nothing but basic apps loaded on the device.
It just started today. I was working on my bf's Vibrant (another, more successful story) and grabbed my Nexus and hit the power button and it did not turn the screen back on. Holding the power button down did not reboot the device, and none of the buttons would light up or function.
So, I pulled the battery. Now every time I try to boot, it hits the "Google" screen and stays put. I left it alone for 5 minuets hoping it would finish booting and nothing. The soft buttons will light up, and if I touch them they register the touch but it does not help the phone to boot.
I do know that the phone was basically dead right before this happened, and at first I thought it was just dead. However, its been on the charger for at least 30 minuets- which should have given it enough of a charge to boot up, and still nothing.
What could cause this issue?
I did install a couple of new applications today, and I know the market updated a bunch of them but they're all apps that I've had on several phones (minus the two new ones today) and have never had an issue with any of them. The two new ones I downloaded were OS Monitor, and a 2G/3G toggle for hopes of improving some battery life.
But those are the only two things I've done differently. I've only been using the phone for a week but I haven't had any problems at all, before this.
Now- if worst comes to worst I can seem to get into the bootloader, and through that, stock recovery. So I can try to do a factory reset and wipe cache but without a backup I really kinda hope thats a last resort.
Please help, and let me know if you need any more information.
Thank you!

I understand that you're fully stock which I assume means you have a locked bootloader (everything I say from here on out assumes as such)? First, I'm going to also assume that you didn't update to 2.3.3? If not, then follow the steps in this guide to boot into a custom recovery and from there go to backup and restore and do a NANDroid backup. Now go to mounts and storage and mount USB storage (or whatever its called, don't have my phone right here). Plug your phone into your comp and copy over whatever you'd rather not lose from your SDcard (just in case you have to wipe). Now download the 2.3.3 update from here and put it on the root of your SD card. Now go back and flash this. Reboot and see if you're golden. If so, great, if not try a factory reset.
If that doesn't work go through the steps again to boot into a custom recovery, you might have to unlock your bootloader and wipe all your data (again) and restore your backup and try doing a factory reset with that. Don't worry about unlocking the bootloader, it can be relocked with a simple command and it won't wipe anything to relock it.
Here is the command just in case:
Code:
fasboot oem lock

I got all the way to having clockwork recovery booted up on the phone, but nothing would mount. Everything gave me an error, and factory reset froze...
I don't think there is anything I can even do from here, is there?

Stuck at "erasing" when doing a factory reset?

Anyone else had issues performing factory resets? My Nexus 5 seems incapable of completing it. So far I have tried doing a factory reset from the settings menu 4 times. Every single time it locks up on the erasing step. I don't mean it takes a little longer. I have let it sit for almost half an hour and the little android robot sits there taunting me.
Every time I have had to manually go into the bootloader and sideload a factory image, which works fine.
Any ideas why this problem is occurring? Faulty memory maybe?

Same issue here, phone is getting nice and warm but the little robot just sits there twiddling his antennae. Forced restart either normally or into recovery mode lands me right back on the erasing screen, looks like nothings going to happen unless I intervene another way. Any ideas?

Try pushing the system.img using fastboot. Might be best to start over and do a clean install.

Have you tried doing a factory reset in recovery instead?

Same problem
I have the same problem with the loop at the erasing screen. It will not go into recovery so that I can fix it. I tried flashing the Stock Rom again but no use. Please help me or at least give me some pointers what to try next.

What is your recovery? Version # also? How did you root? <--- this goes to the rest of you guys too because it seems like its happening to more than one person.
Follow this: Maybe flash the stock recovery found in here http://forum.xda-developers.com/showthread.php?t=2513701

All I want is to factory reset
How did you actually sideload factory image?

ADB sideload: place the rom you want to flash in the fastboot folder and in the phones recovery select adb sideload, then on the pc in cmd type: adb sideload namerom.zip and it will start flashing.

Exactly the same problem here. Nexus 5 running 4.4.2 kept powering off randomly roughly once a day. Attempted a factory reset and it got stuck at erasing. Having unlocked the bootloader and following the steps to unlock and reboot, I have a progress bar with the animated android icon, apparently stuck at the same stage, but without the "erasing" caption.
As far as I'm concerned, I can nothing with the phone at present short of taking it back, though they'll likely take issue with my attempts to rectify myself

I'll add that I've also tried the Nexus Root Toolkit v1.8.0 to flash stock. Appears to go fine, recreating the file system and loading software, then as soon as it gets to the "erasing cache" step it just sits there for hours and makes no progress.

I know I probably shouldn't promote toolkits but you can always try this. Seems to have worked for a lot of people.

Same thing happened to me yesterday. My N5 is rooted, running stock rom and recovery. I had some corrupted app date showing in Titanium that I could not remove that were causing a Play store issue for me. I backed up my phone with TB and ran a factory reset in settings. The phone was stuck on the 'erasing' screen for maybe 20 minutes, so I put the phone in fastboot and from there back into recovery. This took me back to the 'erasing' screen to my dismay. I put the phone down and started searching for a solution online, but then I noticed after about 7 minutes the erase process had finally finished on its own and the phone rebooted normally again.
Based on what others are saying in this thread it appears the factory reset process via settings or stock recovery can hang sometimes. If you power off, start the phone in fastboot and select recovery again, I'm guessing the factory reset process restarts and hopefully it will then work properly the next time, like it did for me.

Well when I did a factory reset from settings, it took nearly 20-25 minutes to finish. The next time I did a reset, it completed within 10 minutes
I guess this problem occurs randomly.

Be patient
My guess is that you just need to be patient -- my device took nearly 45 minutes to reset. It seems to me that the time required is proportional to either the amount of data or the number of files you have on the device. My device had a mix of large files (such as musics and photos) and many many small files (sensor data log files), so it's hard for me to say which of those contributed more to the long reset time.

This worked for me too. On the initial 'Return to factory defaults' it got stuck for about 45 minutes. I then follow the advice above:
- Put the N5 in Fastboot by pressing: Vol. Up + Vol. Down + Power
- Select: Recovery and press on Power to proceed
- Phone reboots, still into the 'Androidman' but it seems that the 'Return to factory defaults' also restarts.
- Wait about 10 minutes and the Phone powers down automatically. Upon startup you enter the 'Initial configuration menu' so the factory reset has been completed.

Still stuck on Erasing screen, running out of options
Hello,
I am a newbie with zero developer knowledge and received my Nexus 5 in the mail yesterday. I liked the phone specs and that is the only reason I got it. I left it alone while it charged up and the first thing I did once it was finished was perform a Factory Reset (it was a "like new" phone so I just wanted to be safe) and have been stuck on the Erasing screen ever since. Pressing Vol- and Power button does take me to the bootloader screen, however, any option I choose by pushing the power button, such as Recovery Mode, sends me back to the Erasing screen. Pushing Vol+, Vol-, and Power shuts the phone off completely. Holding the Power button down does nothing more than restart the phone into the Erasing screen. I have also let the phone die twice and as soon as it has enough juice to come back on, it goes straight to the Erasing screen. Everything on the phone is stock and it is completely unrooted. The bootloader screen also indicates it is unlocked. I have attempted to flash it as per instructions I have found on here but I am unable to download the stock factory images. It gets to about 90% before the install fails and I have tried to install three times already. I do have the 15 Second ADB installed, however. I assumed the install of the factory images failed because I don't have WiFi and I'm running completely off of limited 3G data (I live in the middle of no where with no high speed internet to speak of). So in lieu of all that I have attempted, is there ANYTHING at all that can be done to get the phone off of this Erasing screen? Or do I just need to try and return it because it's useless at this point? I did at first let the process run but it's now been 24 hours stuck on this Erasing screen with no improvement. I'm fairly certain it runs KitKat 4.4.0.

[Q] Hard Bricked, Security Error Boot Loop D800 after Lollipop OTA attempt.

Hey XDA,
I have a D800 that is totally stock. I have no custom recovery, and have never rooted the device.
A couple days ago I got the notification for an OTA update. I hit the notification, and rebooted the phone. It started the update process. It got through the first step. When it started the second part of the update, a black box popped up, and a code like "ERR 0x04ff" or something like that popped up. The phone rebooted, and got stuck in a boot loop with a "Security Error." The phone will boot up, show the LG logo, then show a slightly different LG logo with "Security Error" underneath it, then reboot and start the process over. I started messing around with the power button and volume keys to see what different modes I could boot it into. Initially I could boot it to the Factory data reset screen, the Hardware Mode Keys screen, and I got it into Download mode once. I didn't have any of the software or files available at the time to do anything with Download mode, so I opted to try a Factory reset. The phone attempted a Factory Reset. The little android with wiggly ears, and the spinny cube thingy popped up for about 4 seconds, and the phone rebooted.
Since trying that initial Factory Reset, I have been unable to get the phone into Download mode. I've tried doing the Factory Reset multiple times to no avail. I have not seen fastboot at all.
At this point, the only thing I can do with the phone is boot it to the Factory Data Reset screen, and to the Hardware Keys Mode screen. It will not do a factory reset. The android pops up for about 1-2 seconds, and the phone reboots, and goes right back to the boot loop with the security error.
I'm at a loss at this point. I've called AT&T, and unfortunately my phone is out of warranty by about 3 weeks. So they can't just mail me a replacement. Does anyone have any ideas? I can't seem to get it to be recognized by my PC, on Windows or Ubuntu. I get the feeling that it's just hard bricked, and there really isn't anything else I can try.
Any suggestions would be greatly appreciated
TL-DR: Totally stock D800, no custom recovery or root. Security Error Boot Loop after OTA attempt. No download mode or fastboot, factory reset is ineffective. Not recognized by PC. What do I do now?

Thanks for the reply. I was about to reply saying my phone wouldn't go into download mode, but then I randomly decided to use a different usb port, and now it went into download mode.
I'll give it a shot now and see what i can do

Ok, It seems I'm back up and running. I followed this guide http://forum.xda-developers.com/showthread.php?t=2432476 which re-flashed me to 4.2.2. I'm going to try and upgrade using LG PC Suite from my laptop, and see if I have better luck this time.
Lesson learned, try every USB port when trying to boot into download mode.
Thanks for the help

Bricked or hardware issue

I was charging my phone overnight. In the morning I realized it didn't charge, I tried to turn it on and it gets stuck on the HTC screen.
I was running Viper One 3.21, I tried rebooting, entered recovery, tried to reinstal a nandroid, got stuck on the screen again.
Tried reinstalling ViperOne same problem.
Here's what I know:
Fastboot will NOT work, while I can get to fastboot, any time I reboot the phone it gets stuck.
I can't get to RUU (because it wont go past the HTC screen).
adb sideload will not work
I've let the battery drain, fully charged it; no change.
I tried wiping and doing a factory reset but it just gets stuck on the reboot, I also noticed on the File manager within TWRP that my phone was never wiped.
Any ideas?

Sorta sounds like one of the bricked ones where the entire emmc goes write protected. If you can't get fastboot or ruu mode and have no warranty left I can take a look at it for you. I'm in PA so it wouldn't take long to mail it here.

Not sure how it got bricked, it has been over a month since I flashed anything.
I am able to use adb sideload, but any file I use it says is corrupted.
Could I partition part of the drive and try to instal from there?
What part of PA are you in?

[Q] Cannot wipe or flash anything, stuck in decryption screen.

I am stuck on the Decyption screen where it says "To start Android, enter your password". I have seen a few threads about this issue but they managed to solve the issue by reflashing or re-unlocking the bootloader. However, I am unable to do any of these things.
I have been on ViperOneM8 for quite a long time now and everything was working fine. I unlock my screen by swiping up on the screen while the screen is off. Felt the vibration to unlock but the screen stays blank. Had to force reboot it to make it work again. A few days later, this exact same issue happened again, but before I was able to reboot the device, it rebooted on its own and went into the said decryption screen. I enter a random word for password and it says, password is correct but data is corrupted; must factory reset to use phone.
Alright, so I have factory reseted, nothing happened. It wiped my data and sd card, same decryption screen.
I've used the bootloader to flash a stock android, I remember it succeeded but restarted to the same screen.
I've used twrp to re-flash multiple roms, all succeeded, restarted to same thing.
I've wiped data, full wipe, you name it, restarted to same thing. Once it reboots it would show the ViperOne boot, so something isn't wiping.
I even went into the phone's data and manually deleted everything in internal storage with my pc, restarted the phone, same thing. Checked the internal storage again, everything that was there got restored.
I've used adb and fastboot to push data, same thing. I've used the dottat .exe installer, goes through the entire process, reboots... same thing.
I've tried reflashing another recovery, success, but it boots into the same recovery.
I've tried doing the SuperCID and going through htcdev to unlock the device again, but it fails when pushing the key. SuperCID also resets whenever I restart the device. I've tried locking the bootloader with fastboot but that fails.
One thing I couldn't do is boot into the RUU mode. 'fastboot oem rebootRUU' doesn't seem to work for me. It reboots the device but boots up and goes into the decryption screen.
When I try the 0P6BIMG with bootloader, it seems to restart before completing the installation now. But I remember it went through successfully before, but still boots into the decryption screen.
It seems like no matter what I do, the phone restores itself to the previous state that it's in. That or nothing is actually affecting the data.
I am at a lost of what to do. I feel like maybe it's a damaged hardware but at the same time I am unsure. Anybody have any suggestions at all?

Sounds like you have one of the few that have been popping up where the entire phone becomes write protected.
Before running the ruu run the following fastboot commands.
Fastboot oem task 28
Fastboot oem task 29
If any errors re-run the command.
Then run ruu.

I tried those commands and it looks successful, but once I rebootRUU it would just reboot and load to the decryption screen again.
I also tried the 0P6BIMG method after those commands, no luck.

Sounds like your phone did end up write protected. You need a new motherboard.
The ones I have seen like this don't even allow you to lock the boot loader or turn s back on either.
