another app2SD thing after flashing a new rom?
well then you know more then me. If you can get into bootloader you should be able to get into recovery mode. You can also toggle USB mode, so you can be connected to your comp. In that case you can push a recovery image.

you can also wipe
etc
its all in that thread or somewhere else on this forum

Any updates? same thing happened to me.
If in doubt then reflash everything again;
boot
system
and recovery
and start afresh.
see thats the thing,, i can click recovery from the bootloader screen and nothing happens. It will restart and just sit on the same "X" screen. Its very simple to put a phone into a DFU mode or recovery mode for Iphones,Motorolas,blackberry,nokia,samsung,Lg, and a few more i cant think of at the moment. When these phones become corrupt ive learned how to whatever firmware or software i want on dumb thing.. But this HTC is giving me a hard time and i know its something simple.. Most phones have a desktop software that will allow you to mess with phones programming, Itune-iphone/Blackberry-BB desktop Manager/motorola-RSD lite....ect. BUt i cannot find anything really for the HTC or just this N1. A lot of these programs for other brands, once you plug your phone in, will notice that the phone is in a recovery state and offer to do an update or a restore. Now why doesnt the N1 or do they, does google offer something like evryone else does?

hmmm I understand your frustration. What did you do before it got to the 'X' splash screen?
I'm assumimg you've tried to reflash a different ROM in recovery mode?

The SDK can do that
like the others said, try get into recovery and reflash everything
SDK? i just turned the phone on and its stuck on the "Splash" screen just a big ol "X". I press volume down and power and pull up the bootloader menus.. i scroll down to recovery and press enter. and it reboots and stays at the damn "x" screen again. I've chosen everyone of the options it offers in that menu and nothing changes.. You know how when u first open that menu it will scan the SD card? Well it shows up for a second then goes away, and in the split second the green lettering is on the screen i swear it says "no splash image" or something like that. UHHHHhhhg!
Hmm I forgot how to get to get to recovery using physical buttons, sth like: power + trackball, or volume down + trackball i guess, so try that
So it looks like your phone is not rooted and you don't have Amon_Ra recovery maybe you have not even turned on USB debugger? tough luck friend
All is not lost if you can get into fastboot mode trackball and power together then using adb reflash boot,system and recovery images.
Or call Customer Service and trade in for a new Nexus One
if not you have to download the SDK http://developer.android.com/sdk/index.html
find stock images and reflash like the above post said

agreed....if you haven't "unlocked" the bootloader then i wouldn't bother with any of the suggestions....Call customer care and get a new one before you un-lock it and this mysteriously happens again...THEN, you'll be S-O-L!!
EDIT: Then with the new one, follow all the threads for un-locking, flashing recovery, nand,flash cyan, flash gapps LALALA
DOUBLE EDIT: Althought it sounds all you've done is messed up the recovery image, which you could re-flash. Then you could get into recovery and flash Cyan, having a functioning phone again

Hi,
My brother is having trouble with his Nexus 4 and I was hoping I could get some help here.
The phone won't go past the boot animation, with the 4 floating balls.
It keeps showing that forever (left it for 20 minutes with charger, phone got really hot but did not get past the animation)
- Never rooted or changed firmware. Only updates from Google. (It was on 5.1.1/5.1/5.0.1)
- Sent to a shop, which claimed it can't be fixed (I do not know the reason they gave him).
My brother thinks it is because a weight was accidently dropped on the phone, but the problem only started 3 days after the incident.
No outer damage can be seen on the device, other then a small brake in the back glass.
Thanks in advance to anyone who will try to help
possibly?
Did you just update and it got stuck at the booting up????

Do you have data on it that you want to keep? If you don't you can try booting into the bootloader and unlock it. Then try flashing a factory image. This will wipe all the data on the phone though so that should probably be a last resort.

I have no important data on it.

First we should check if you can boot into the bootloader at all. First turn the device off. Then hold down both the volume buttons and then press and hold the power key. Keep holding all the buttons until you see some different colored text. If that happens we should be able to install a factory image, if it still gets stuck on the Google logo I unfortunately don't have any more ideas.
Tried pressing both volume keys and power button. Google logo show for a second, then black for 2 second, thank flashing red notification light every 1/2 second until I let go of the buttons.
When I release the buttons, the phone goes back to charging battery screen.
I see people suggesting that the red light flashing means a battery problem, but the device keeps trying to boot up while it is not plugged to the charger, unlike what happened to them
Any Ideas why this is happening or what the red light means in this case?
You need to press volume down+power button to get into bootloader. Unplug the charger before doing this.

Oh it was just volume down, not both. Heh, sorry.
Use the Nexus Root Toolkit (NRT), it's the easiest way to unlock, root, flash and manage your SuperUser needs!
http://www.wugfresh.com/nrt/
Not sure, but maybe?
You can try using the nexus root kit & unlock your bootloader and see if a factory reset can work. If it does you can always relock it again ☺..Flashing a factory image can work too also ...
Tried volume down+ power button while unpluged from charger.
Google logo show up with vibration, then goes away after 2 seconds, like before, but then the screen goes blank. But red led not flashing.
What should I do now? Even just to use the Nexus Root Toolkit I have to allow Developer mode, which I can't as the phone will not boot up.

I'm you can't get into the bootloader then I am unfortunately not aware of any way to help you. If you can't even get into the bootloader I think it is a high probability that it is a hardware problem.

That sounds like the battery is completely empty. Put the device on charger over a night and try then to boot into the bootloader.
Once I had these symptoms (red light flashing) on my N4, it was enough to charge the battery for one hour. Then it booted properly. It's worth trying.

How do I do that?
Hi all,
I'm sure I am still one of many that cannot use XCnathan32's solution to fix their phones. I think the biggest problem is that it is difficult to discern between hardware vs. software being the culprit. If hardware, nothing I do can help. I've wanted to use the solution but when the computer cannot even find the device/recognize it, I cannot even start the solution. Let me explain what my phone is like/ the state the boot loader is in:
Google logo is the only thing to show.
Even when trying to boot from bootloader -> recovery mode, it only goes to the google logo and boot loops from there.
Unfortunately I did not unlock developer options / USB debugging so my bootloader is LOCKED, my computer does not recognize the 6P at all unless in boot loader. It gives a strange description of the device, but does not treat it as a device in the device manager. Even if it does show I cannot update it's driver. It essentially seems like only the bootloader is a device rather than the phone.
I have tried leaving the device to boot in hopes of it miraculously starting and allowing me to go to developer options, this has failed as well.
Would anyone know/ be willing to explain how to proceed from here? I'm sure the options are limited when the device does not even show up on the computer.
Note: I don't know much about TWRP, ADB, SDK etc, its all 2 days new to me.
Thanks for any help!

That's the exact guide I used. I also used his first guide before that one was published by XDA. It almost seems too simple though. I feel like I'm missing something. I flashed the 48B_A4 firmware, then the twrp3_1_1_4Cores.img and reboot. It still boot looped. I then proceeded to flash the other possible imgs to see if they would work. I cant flash the EX kernel since I can't boot into recovery since it just boot loops again.

sorry to hijack your thread, can i know the steps that you took to enable oem unlock ?
Because i am in your similar situation, all i can see is the google logo & bootloader is locked (i cannot go to the settings menu because the phone doesnt bootup, i am stuck in the google logo).
If i run the fastboot flashing unlocl it fails (since bootloader is locked)

Hi there - I ended up having to use a blow dryer to throttle the phone using High heat. I wouldn't recommend it, it wasnt safe and my phone after fixing stopped working in an hour. If your phone isn't working despite following the fix above get a new phone, the pixel 3a seems like a nice new option, good luck!

OK, I don't have a bootloop problem per se, but I changed my battery and now it only goes to the Reboot bootloader screen. The arrow keys don't work to change the menu. Sometimes I can get it to Recovery mode, but neither the power key or arrow keys will work. Once I got it to the Start, but the power key did nothing. ADB devices returns nothing, so even though I installed the Google USB drivers in Android Studio I can't get the computer and the Nexus to talk to each other. I'm ready to try heating the device, but that goes against everything I've ever known about electronic devices. Are you sure? .

well then ask your asshole uncle what he did, because maybe if we have a cause we can have an idea of what went wrong at least.. can your computer connect to it at all via adb and fastboot? have you tried holding down the power button and both volume buttons to boot it up (this boots you into bootloader mode)?

data won't be wiped unless you wipe data, but no garuntees. And hey, a fixed tablet with no data on it is better than a broken one with data, either way you can't access the data, at least one way you get a shiny new tablet!
here is a download for the stock firmware for nexus 10 (5.1.1): https://dl.google.com/dl/android/aosp/mantaray-lmy49j-factory-b24f40e6.zip
just unzip it and the zip file inside it (a zip file is in a zip file in this scenario) to get the images, you should see an obvious bootloader one. TO try and finesse the tablet with it, do this:
1. Before powering on the device into the bootloader, type in "fastboot flash bootloader [file path to downloaded bootloader file, you can drag and drop it into terminal to get the exact path]"
2. hit enter, it should now say "<waiting for device>" if it gives a file not found error you entered in the path wrong, drag and drop the file into the terminal, its easier.
3. now connect the nexus 10 and power it into the bootloader
4. your terminal *should* begin flashing bootloader, if not we will try something else.
