Stuck on Google logo boot screen -- Bricked??

I unlocked the bootloader and flashed a custom recovery. I then rebooted the device. Now it is stuck at the bootloader (white Google logo on black background) and I can't get it to do anything else. I've rebooted it a bunch of times including with the vol + and vol - buttons held down to no avail. I've also let the battery run out and then tried to boot it up again and the same thing happens. adb nor fastboot see the device and it doesn't show up in the logs on my machine (Mint 13) as coming online at any time.
Most of the times I reboot it with the power switch it reboots to the Google logo even without me letting go of the power button. Sometimes I can get it to fully power off but I haven't figured out what combination of vol keys and reboot does that.
Anyone have any ideas what could be wrong? Any help would be much appreciated!

You are not bricked if you can still get into the bootloader.
Download the factory image from here, and flash it with fastboot. If you don't know how to do that, read this thread.

I wish I could get fastboot to see it then I could definitively flash that img.
I can't get into the bootloader and can't get fastboot or adb to see it. It's stuck at the Google logo now and when i hold the power key it reboots back to the Google logo with the unlock logo at the bottom.
Thanks for the help

You've tried holding volume down+power for 10+ seconds? That should power off the device, then hold both vol up+down down and power up

Ya I've tried to hold vol + and power for 10+ seconds and it reboots back to the Google logo even if I don't off the power key. Same happens with all the other combinations of keys being held with the power button. I can't get it to turn off now unless I let the battery die

Press and hold power till screen goes black. Then quickly press power+volume down and HOLD.

Tried that and still stuck at the Google logo. I have to go to work for a couple hours and then will hack on it when I'm back. Hope I don't have to deal with Googles rma process seeing how disorganized the rest of that company is

No luck with any button combos but the vol + and power actually turned it off. All out of ideas over here. I'm thinking it really is bricked

I'm in the same spot. I can get it into recovery occasionally but once there it locks up after trying to flash or clear the cache.
I'm wondering if a contributing issue is CMR v6.0.0.6? I updated it from 6.0.0.4 that was running fine. But no fastboot or adb so that is doubtful.
This is frustrating and not a great start with this N7.

thank you

this worked. you have to be fast. as soon as screen goes black release power button then quickly, very quickly repress along with vol up and down.

You will still be able to get into the bootloader! Force kill the tablet by holding the power button for ages. Then hold volume up and volume down and the power button together, which will boot to fastboot.

It looks like a CWM bug as I feared. Anyone in the same boat try here - http://forum.xda-developers.com/showthread.php?t=1782932

Nothing has worked and I've literally tried everything that those three buttons can do. Thanks again for all the help guys. Had a great time trying to resurrect it but guess it's time for it to go back home
Just as I suspected. Google puts out buggy junk once again.

I just wanted to report a similarly event. I have a rooted, unlocked Nexus 7, with TWRP recovery. I have previously rebooted without issue. Tonight I booted into bootloader mode to check something and the hit power button to choose start. I got stuck on the boot logo. After finding this thread, I started with the simplest combination and held power button until screen went dark, then added volume down and once again in bootloader. This time choosing start led to a regular system boot. It's as if the device froze and needed a hard reboot.

I was attempting to boot into recovery and kept getting the 'Google' logo (I am unlocked/rooted with twrp recovery). I wasn't aware that one had to be plugged in via usb in order to *not* hang....
Any way around this?
Once I plugged it in and attempted to boot into recovery it worked fine.

I had a similar issue after using the Nexus Root Toolkit to flash to nakasi 4.2 with CWM recovery - just got stuck on the nexus boot screen, flashing in a loop for over 15 minutes.
I ended up powering down the device, holding power for about 5-10 seconds - then QUICKLY holding both the power and volume up+down keys, it then went into the fastboot screen.
After it was there, plugged it into my PC.
Now, this should work for you - assuming you have all the fastboot/usb driver stuff installed.
I extracted the contents of nakasi-jop40c-factory-6aabb391.tgz into the same directory as the fastboot.exe provided by WugFresh with his Nexus Root Toolkit (google search or xda search for this if you dont have it, i dont think i can post links due to my low postcount) - typical filepath: C:\Program Files (x86)\WugFresh Development\data
By the files in there, I mean drilling down inside the tgz to where the image files were inside so that files like bootloader-grouper-4.13.img, image-nakasi-jop40c.zip etc were extracted into the directory and sitting alongside the fastboot.exe - NOT in a subfolder.
Once its all here, running flash-all.bat (this is provided by google in the nakasi-jop40c-factory-6aabb391.tgz) from the command line or by double clicking on it from explorer should kick off the process. After about 2-3 minutes, it was complete, and my Nexus then booted up within about 3 minutes after that.
Also worth noting, device remained unlocked, but I lost root/root binary

[Q] Unbricking Zte Blade 3

First of all thanks for not caring. I spend days on Internet trying to find a solution. I have Blade which I bricked thanks to my noob skills with flashing and similiar ****. I just want my normal phone back. Couldn't give a **** bout roms anymore. Sorry for the lang but Im mad. When I boot it up it just sits there on green android logo not going past. I can enter download mode if it matters. As soon as I back it up Im getting rid of cwm mode and bull****. I use my sister phone to transfer files on my sd card. I cant enter my recovery mode since I installed that **** of cwm.When I try the key combo-android logo stuck with red light on. My phone has 90-100% battery Im sure. I need a solution where I can do something from pc with download mode or something that will automatecly start when I boot up my phone that I transfered on my SD card. Please guys let me have some sleep. I've been staying all night long just to unbrick it. Dont mention any flashing rooting ****ing...I developed alergy to those words. I want it simple ..please...any help is appreciated. And sorry for my language.

Calm down dude. If you can get in Download Mode , you are lucky. I even know people who had not get to Download Mode and had began to cry , cause the phones were only 3-4 Weeks old. Back to your problem.]First download here the stock rom.[/URL]
Then you need the Android SDK and the platform-tools from Google , so download it , cause you need ADB. Click here to get Android SDK.Then you need the ZTE drivers. Click here to get the drivers.Now get into download mode and connect the device via USB to your PC. Copy the boot.img (or recovery.img if it is in the ZIP package) and flash it via Fastboot (command: fastboot recovery.img) . Now you got the stock recovery. Now push the FULL update.zip at your sdcard , and now go to recovery , and update from sdcard , choose the update.zip ... Flashing takes a while. DO NOT WIPE ANYTHING BEFORE OR AFTER CHOOSING "UPDATE.ZIP" . Now your Phone should fully works normally

Hello, I have also bricked ZTE BLADE 3(I flashed a wrong kernel....). It only turns the red light on when i turn it on and blank screen, does not respond to vol + and vol - key, no android logo, but when I connect it to the computer via usb in Device Manager a COM port opens with the name ZTE DFU(Diagnostic interface). If anyone has experience of reviving this device from this mess? Thank you for your time

Your download screen is destroyed , but you are still able to get into it.
Try to get into it and flash the kernel with fastboot , the screen will bug during fastboot procedure.

My screen is completely blank and black, just the red light showing when i turn it on and it is always on. It does not respond on power button + vol. down, power button + vol. up, power button + vol. down + vol. up. When I connect it to the computer it does not show me a usb flash drive although I have the zte drivers installed and another sd card inside, but in Device Manager I can see it as a COM port(DFU) Diagnostic Interface. I tried accessing the bootloader via adb but it doesnt even list it with command "adb devices". I also tried flashing the recovery image via "fastboot recovery recovery.img" and "fastboot recovery.img" and still no luck, it just hangs at "waiting for device"...

When the red light still comes up , you still got chances to get it fixed...

I think so too.. but how? The only method left is JTAG... I saw a thread about using a TPT image to flash low level firmware using ZTEflash.exe but that thread was for ZTE Skate I think, I could not find the tpt.img file for zte blade 3.... Is there any other method via usb cable? Or send it to the shop?

Well, here is my situation:
Got a BLADE III Pro
Tried to root it and i played with few tools found on xda and other places (android forums). No luck at all. Tried to flash a CWM and NO LUCK neither. Tried to go back to flash stock CWM (as i was afraid of bricking it), searched for stock cwm and there is my BRICKED phone. When trying to hold volume down and power botton (both for over 20 seconds even) it will show a green android and its stuck there for hours. When trying to go to fast boot mode the same happens (with volume up and power botton).
While trying these two options the PC (Windows 7 64 bit) wont recognize the phone pluged in.
The only way the PC makes a sound is when i hold both volume up and down bottons and power it or plug it in the PC (without the battery even).
I need to know how can i fix it to boot only. PLEASE. Is this a "throw on can" phone now or it can be brought to life? PLEASE TELL ME PEOPLE.
pm me or any info as soon as you guys can.
I will respond to any question you might have.
Thank you in advance.

I have sent my phone to the shop and they said that they would need a jtag box specific for this model or a new motherboard for zte blade 3.... I think this the end for my zte blade 3

HELP Razr M stuck on Reboot

My Razr M was a bit sluggish so I restarted it. Now it's stuck on the screen with the pulsating Motorola logo. I can reboot using the power & volume keys but that's it. It will not turn off. I can't get it to the system recovery options. It is not rooted.
I just bought a new phone so it's not the end of the world, but I was still have a few files that I need to transfer from my Razr M. I can't get access to the phones' memory buy connecting it to my PC.
Any help would be greatly appreciated & rewarded with cookies.

If it's not a hardware issue, you could reflash the operating system without deleting your userdata partition. App settings etc. might get deleted tough.
You'll need RSD Lite and your firmware version from here. Extract it, and delete the line which erases the userdata and just to avoid problems also delete any lines that contain "GetVar", "var" or "oem" Don't forget to save the changes.
Go into fastboot mode first:
Turn off or reset your phone first by pressing and holding Volume-up + Volume-down + power for a few seconds until your phone switches into “Boot Mode Selection Menu”, scroll down with Volume-down to highlight “AP Fastboot“ then press Volume-up to select it, you will get into ”AP Fastboot Flash Mode“.
Click to expand...
Click to collapse
then open RSD Lite, select your modified XML file and flash by clicking "Start".

No sure what my firmware is other than JB. I'm also in Australia. Those firmwares all say US, does that make a difference?

Yes, I assumed you have the XT907 (Verizon). But if it's the Australian XT905, you would need an appropriate firmware.

Have you attempted to boot into the stock recovery?

Fastbooting does nothing. Guess I'm just gonna have to accept that it's bricked.

So you flashed the system and it still doesn't boot properly?
Maybe there's something wrong with the userdata (but rather unlikely). The last chance would be to erase this partition too (leaving the appropriate line in the XML). If it's still bricked after it, then it's a hardware issue.

I put the firmware on an SDcard & put the card in the Phone. That's as far as the process will go. Nothing else will happen.

I believe the stock recovery cannot install images from SD cards. So that won't work.

There's no other way to get anything on the phone. When I try & connect it to the computer via USB nothing happens.

You have to go into fastboot mode first, then you can connect it.

And that's the problem; it won't go into fastboot mode.

It has to. You wouldn't see the Moto logo otherwise. Press and hold Power and both Volume buttons, wait until the phone resets (and a few more seconds) and then release just the Power button. You should see the options menu, where you can select fastboot (or even just recovery as poppers162 suggested).

I've done that. It never works. All it does is go back to the logo. Nothing else.

It has to.... If that didnt do it. Hold vol down + power for ten seconds once you see the screen flicker hold vol down + vol up... Then select which ever option you need...or if its rebooting over and over then just hold vol up + vol down and wait on the reboot

[Q] Secure Boot Error, No Download Mode, No Fastboot, No Regular Boot.

Hello all!
Just a newbie here, but hopefully I don't break any forum rules.
Now, to the problem at hand. I have an LG D802 that cannot be booted normally, cannot be brought into fastboot or download mode.
When trying to power on, I get greeted with "boot verification error / secure boot error".
This happened after trying to flash the "Cloudy G2 3.0" (lollipop version) ROM onto my phone via TWRP. Everything seemed to be in working order until
I had rebooted the device. I think the problem stemmed from the fact that I didn't read that the ROM was only for a different variant of my phone.
I have had a look at one post ( http://forum.xda-developers.com/showthread.php?t=2582142 ) but found it too hard to actually follow the instructions,
so now, I am here, writing this post.
Please feel free to ask for any additional information!
Thank you in advanced.

Guy, guy, guy..... It's clearly write in the FAQ section of CloudyG2 3.0 that the rom is ONLY for F320' series, but no, you still want to flash it in D802.. Anyway, do you have access to recovery mode? Key combination might be power key + volume down until LG logo appears, then those keys again or power key + volume down until lg logo, then volum down + volume up.
For download, try a simple thing: Press your power key for ~1 / 1min30, just to be sure it's poweroff, and then try volume up + plug USB cable

Yes... I know. Was very silly in doing so. I have no access to recovery mode using both of those methods you have stated. When trying to get into the download mode for the phone, I get the same error, it will say, secure boot error etc. then the screen will go black, and a bunch of drives pop up on my computer, from [A] - [K], and windows asks me to reformat all of them.

Update: When plugging device into computer, it says QHSUSB_BULK. Hopefully that helps a bit

N7 (tilapia) stuck at logo - no fastboot access ...

Hello everybody,
I hope somebody can help me to save my N7 (2012).
I installed TWRP without problems and after that I tried to flash a custom rom - which, for some reasons, didn't work.
After reboot my Nexus is stuck at Google logo with an opened lock at bottom...
I can't get to fastboot because when I power on while pushing VOL - button it just get stuck at the same logo screen.
If I keep power button pressed for about 10s, it shuts down but after a few seconds it boots again just to get stuck again at the logo screen...
The only way to shut it down completely is to keep VOL+ button pressed while pressing the power button.
My Windows 7 computer won't recognize the N7 at all anymore, but when I shut it down completely (Power & VOL+), windows says "Unknown device".
Is my Nexus still to be saved or I can throw it away?
Thank you in advance for each advice.

Hi, Conrad-007...
This is very strange - your Nexus 7 is clearly 'bootable' (sort of), with a functioning bootloader, ie., it's not hardbricked... or you wouldn't be seeing the Google logo.
In the distant past, back when I used to experiment with custom kernels on my Nexus 7, it sometimes required the POWER BUTTON+VOL DOWN buttons be pressed and held down for a good 30 seconds or more, to generate the necessary 'interrupt', and force the device into the bootloader.
My first instinct, is to suggest you may possibly have a problem with your VOL DOWN button, and maybe it's stuck somehow or not making contact.
It also occurred to me, that you might be able to access the bootloader with...
Code:
adb reboot bootloader
...or possibly...
Code:
adb reboot fastboot
...and even...
Code:
adb reboot recovery
But unfortunately, I'm pretty sure you need to be running fully booted Android or booted into a custom recovery (eg., TWRP) before you can issue ADB commands. I haven't tinkered around in this area of Android for a couple of years now, so my memory of the specifics is a little hazy.
Anyhow, here's a fairly comprehensive listing of Nexus 7 button presses/interrupts, which maybe of some use...
https://forum.xda-developers.com/showthread.php?p=37606945#post37606945
--------------------------------
Anyway, just some thoughts that might give you some clues/ideas, that may resolve your problem.
Good luck, and I hope you find something that works.
Rgrds,
Ged.

Thanks Ged for the detailed answer.
Unfortunately it seems that my Nexus is not booting complete (not finishing the booting sequence due to corrupted bootloader?) and so I cannot send to it any adb or fastboot command...
I read in the meantime that holding the VOL up button while powering up the Nexus, it will bring it in the APX mode (whatever this mean) and indeed, my computer recognize it as "APX" device.
I hope at least that this is a good sign and a first step to bring my Nexus back to life... but I have no idea what is the APX mode and what can I do in this mode to attempt to save my device...
Do you (or somebody else) have (has) an advice or tutorial for me concerning this?
Regards,
Conrad

Hi Conrad.
I'm in exactly the same situation (I've mistakenly posted a duplicate thread here https://forum.xda-developers.com/nexus-7/general/bricked-tilapia-t4005149). Let's continue here. So:
1. I spent 4 hours trying all possible button press combinations, including VERY long presses. I didn't notice any APX device or Uknown device connected to Windows. I might have missed it, you gave me hope. I will check again.
2. APX mode enables low level access to the chipset via nVidia tool nvflash. You probably came accross these threads here on xda:

I haven't so far, as I was not aware of the visibilty of the tablet in Windows. I will check again.

Well, I must have been blind not to have seen all the posts here on xda and everywhere else. I went through the threads and now I know:
1. I can see the tablet in APX mode in Windows. Possibly I could correctly set up the driver.
2. This would be totally useless, since I hadn't backed up necessary blob.
