Hello,
I've got a problem. On monday my Nexus 7 2012 (with lastest stock Android) froze and I had to reboot it. But then it got in a bootloop where it would boot to the boot-animation (the four moving dots) and then restart after half a minute. Then I went into the bootloader to switch it off. When I switched in back on it just got stuck at the google logo.
I tried to reflash the stock rom, but I haven't unlocked the bootloader yet and everytime I try to do unlock it, it fails with "unknown error code".
At first I used Wug's Toolkit. When that didn't work I used cmd, but that doesn't work either.
I would really appreciate some ideas to solve that
You dont have to unlock the bootloader to flash factory images.
You can flash it with fastboot or a toolkit.
Did you try to get into recovery?
Maybe you can wipe some thing like cache, dalvik cache and system,
And then install the firmware again.
I once installed a firmware without properly wiping and also got stuck in thjis animation logo.
After wiping in recovery and re-flashing the firmware it worked again.

As far as I know, you need to unlock the bootloader. Anyway, I tried a toolkit as well as fastboot via cmd but none worked.

In order to do anything useful in fastboot, the bootloader must be unlocked

I dont't have any custom recovery installed. When I am trying to access the stock recovery mode via the bootloader then I get to the Google logo and "booting failed" is written in the upper left corner.
My guess is that the emmc is broken
Google search android factory images, download the appropriate one for your device
Then extract contents and double click the flashall.bat
If this fails then chances are your emmc has been severely corrupted, I've seen a few get to that point with the booting failed and its 50/50 if they resurrect their device
Best of luck
(Oh and don't use toolkits)

I tried that again the way you described it and sadly it didn't work. I have to accept that the emmc is corupted.
Thanks guys for your help anyway

I just sideloaded the 4.3 update to phone and now it's stuck on the 'X' loading screen.
My phone was rooted, but all stock (including the bootloader). I used the sideload ADB command and everything went fine, but the phone now won't boot.
How do I fix this?
did you data wipe(factory reset) before flashing?? if not, you have too.
I applied the OTA...didn't think I had to
Any idea on how I fix it now?
Really don't want to lose all my data

I do not think because you have to change recovery you must unlock the bootloader and unlock bootloader wipe the phone

no, its the data(and other stuff) causing it not to boot. same thing when flashing custom rom, you wipe when fkashing different roms. and going from android 4.2.2 to 4.3, theres many changes, enough to consider it a different rom.
Shoot...I should have done more research before doing this.
I did a factory reset through the stock bootloader...but it's still looping on the 'X' screen.
Can someone walk me through this or point me to a guide?
Bootloader is currently unlocked and I'm able to get into the factory recovery.

yea, the zip youd want to wipe data/factory reset, then flash the rom. dirty flashing wont help since the changes are big enough.

I bought my ole lady a Nexus 4 for Valentines day, anyway, today she got the OTA update and let it install the update. Now mind you she is 100% stock, adb debugging was not enabled, and her bootloader was still locked. (She would not let me touch her Nexus 4 lol) When the device rebooted it stuck on Android Upgrading finishing boot. So I said well let me see what I can do, this is what I did to fix it.
I use only Ubuntu so this may not work on windows i do not know. I Booted the device to the bootloader, connected it to my laptop via USB. I opened a terminal and typed in "sudo fastboot devices" and entered my password when promted and this gave me the device ID and fastboot letting me know fastboot was working. I then typed in "sudo fastboot reboot" and the device rebooted but was stuck on the bootanimation. I opened the internal storage up on my laptop in my file explorer and made a copy of her internal storage. Next I booted the device back into the bootloader then opened a terminal and typed in "sudo fastboot oem unlock" and the device gave me the unlock warning and the yes or no options. I selected yes so it would factory reset. After it did the factory reset the device reboot and booted to the setup welcome screen. Hope this helps others, also thanks to my good good friend Ljjehl for reminding me to use "sudo".
Edit: If you open the command promt with Administrative permissions in Windows this will work in Windows as well. Go to C:\Windows\System32\cmd.exe and right click on the cmd.exe file and select run as administrator. Then CD to the location with your fastboot.exe command. Thanks to another good friend TheBr0ken.
Thanks for the help...
I just ended up flashing each of the 4.3 components from the factory image. Just annoyed that I lost everything...
I'm stuck at the same screen. I received the OTA update, I didn't do anything special. My phone is unlocked and rooted (or WAS) but that was months ago, the rest is stock.
I think having encryption on my phone may have made it do this. I don't think Google anticipated doing the update properly for encrypted phones. Now I fear I've lost everything because even if I could connect, all data is encrypted...
similar problem
After starting to OTA update it was going smoothly, i was making breakfast, came back to find my screen at the "starting apps" screen frozen. The little circle that rotated wasnt doing anything so i left it there for awhile longer and still nothing. It would not move off that screen so i held power button down and restarted. now its stuck at the X screen also.
Yeah, I'm stuck there too. Already tried Factory Rest, didn't work. So what can I do?
I was on stock 4.2.2 and unrooted. I used the 'Google Services Framework' hack to force the 4.3 OTA update. The update downloaded successfully, phone restarted to apply the update and then restarted again. And now its stuck at the Google screen and keeps on restarting :crying:
I dont have the USB drivers installed on my PC too.
Same Problem
I have a nexus 4 (stock and unrooted),after 4.3 update,it is lagging during phone lock on/off (2 sec/5 sec).Hence I restarted my phone,and it stuck at "x" logo.Did clean data 3 times and then its working.
The problem is,in 2 days,I have experienced and done above thrice?
What could have gone wrong?
Hi guys,
I've just found how to correct this problem. All you have to do is to correctly wipe your phone before flashing factory image.
So :
Fastboot erase boot
Fastboot erase recovery
Fastboot format cache
Fastboot format system
Fastboot format userdata
I've just unbrick a n4 this way 15 minutes ago.
I have found the problem in recovery where you can see error log saying "cannot mount cache"
So formating correct the issue.
Hope it can help, fingers crossed.

I was having some pretty serious radio issues with cyanogenmod so I attempted to use RSD Lite which had previously worked like a charm to go back to stock rom (using what came pre-bundled with matt's script v. 1.2)
My phone is unlocked at the bootloader
I have it rooted.
I get the original droid boot loop.
I can definitely get it into a status code 3 AP Fastboot, but none of the tools for the script or RSD lite have gotten me past the droid eye bootloop.
I'm presuming a wipe of the cache will do the trick, but either my googling skills are gone or I'm just too tired after 6 hours.... but I'm unable to get any type of recovery flashed.
My first question is if I am in AP Fastboot, who knows how to get a recovery image flashed so I can see if it's just a cache issue of trying to go from cyanogenmod to stock firmware.
My second question is - Does anyone have a link to a guide to "re-lock" my bootloader in case I need to get this to tech support?
Thanks

First off, after you flash the firmware via fastboot, go back into recovery and do a factory reset. Second, you can't relock the bootloader.
thanks for responding. I wish it was this easy - it's been caught in a loop after trying factory again. I think I'd be able to resolve this if there were a way to wipe everything clear and build from scratch

I had some issues with aftermarket recoveries and formatting. I'm not sure if you've had any luck or if this is even helpful but assuming you are in fastboot and have the SDK set up...
Extract the stock sbf/XML and grab the recovery image.
At command line enter: "fastboot flash recovery recovery.img"
Reboot with all three buttons and select recovery.
Do factory reset.
Get back into fastboot
And repeat the command above (with different recovery obviously) to reflash a recovery of your choice.
(The official Philz cwm touch posted recently in development subforum works very well with the new 4.3 ROMs)
Hope that helps...if its too basic, please disregard! Good luck.

Well, i tried to install stock Bootloader, stock recovery and stockrom with wugfresh tool under "Back to Stock", and so thats the problem:
When i try to send the bootloader, it stucks and the tablet posts under the infos on the bootloader screen: FASTBOOT STATUS - DATA00140000.
And thats it. I waited 2 hour, it still stucks on sending bootloader. So i downloaded the Unified Android Toolkit, install the fastboot driver and tick the option to install a new recovery... It still stucks on sending bootloader. In Youtube Videos, i saw, that the sending finished about 0,2 s. Thats 1280kb! Why doesnt work it on my tablet. I had root, but i didnt tick the usb debugging. So when i switch on my tablet, it comes to the bootloader, and its the activated bootloader( i can switch to recovery, reboot bootloader, power off, reboot system,..) and its unlocked. If i reboot into the recovery, it also comes to the activated bootloader. Its also when i tick the reboot system. So what can i do? Is it hardware bricked? Or whats the problem? I have the bootloader version MANTAMF01 and the H/W Version 8. Can anyone helps me?
And yes, i am the Admin on my PC
The problem is the toolkit, just use fastboot
fastboot flash bootloader nameofbootloader.img
And your done
But after doing so you effectively wipe a few of your partitions so then flash recovery and ROM as well, the method on doing so slightly varies depending if your going back to stock or what something custom

Are you trying to return to stock? Download the appropriate factory image (just Google android factory image) extract all and flash with fastboot.
If you want more detailed explanation boot to bootloader and write down all info on that screen, pet me know the os of your PC, and the explain a little more what's wrong, I'm not sure what can't receive any files means. It is often helpful to copy and paste all input/output from cmd/terminal

I just resolved this issue on my own about a minute before your response lol. The problem was that I wasn't using the stock USB cord. Holy cheese and rice, I've been sitting here for the past 5 hours at wits end trying to figure out the problem. My problem was exactly like MrCreeper's, it was just stuck on "sending 'bootloader'" with no progress whatsoever on either PC or tablet. Who woulda thunk the problem was simply that I was using the incorrect USB cord -_- *sigh*
Anyway, thank you for your prompt reply. I did use a few of your tips from your other posts when I ran into other problems trying to flash stock image, so cheers for that!
Hey, I flashed the new DP4. Now I wanted to revert back to MM but the phone doesn't boot up twrp. It just hangs at the twrp splash screen. Fastboot wont work either. REbooting into bootloader doesn't work. Going for it reverts the phone back to the screen where you see an android laying on its back. Evrything enabled except for download mode. Even clicking on starts doesnt boot up andorid n. Android n only boots up when click either on factory or bp tools?? Typing adb devices via adb only show list of attached devices, typing fastboot devices results into nothing
Any ideas how to get back to twrp.
When you say bootloader doesn't work; what doesn't work about it? Your bootloader should look like this http://www.androidcentral.com/sites...exus-6P_bootloader-unlock-1.jpg?itok=aDeXgpNz
From there you should be able to flash the factory image and get a usable phone back.
Yeah if your bootloader didn't work you would have an actual brick(meaning no turning on and nothing on screen). That's the one thing your phone can't function without. Unplug your phone from PC and then hold the button combo to boot bootloader. Then flash a factory image minus the -w command and then flash recovery.

Your bootloader is fine, if it was damaged your phone wouldn't boot at all. Boot into the bootloader and flash the factory images, details in my guide:

It's hard for me to suggest anything because you haven't given any background on the situation. Here's an idea though:
Flash TWRP recovery to the device.
Enter TWRP, enter the wipe menu, select advanced wipe, tick the system, data, cache, and dalvik cache boxes, and swipe to wipe.
Boot back into the bootloader and flash the factory images (minus the userdata.img).
Boot the phone up.
If you need instructions for any of this look at my guide:

I have the US version of the ZTE Axon 7 running the B29 build.
I recently unlocked the bootloader successfully, When I flashed the TWRP recovery via fastboot soon after, it worked perfectly. Phone booted properly and worked normally. When I tried to install the TWRP app in the OS, I was told to download the latest TWRP version from the website and flash it (even though I had the latest version already flashed from fastboot). I did that. Now I have no recovery menu at all. I have access to the bootloader menu, and I can boot into the phone. When I try to boot into recovery, all I get is a black screen. I tried to reflash the TWRP recovery img from fastboot like I did originally with no success this time. Fastboot recognizes the phone when I type devices, but when I type the fastboot command to flash recovery twrp.img, it says it can't load the file. I then downloaded the ZTE stock recovery img and tried to flash that with the same result. I assume the recovery partition is locked somehow now? What can I do to recover the recovery? Am I stupidly forgetting something trivial.
hello, this happened to me once on a Nexus 7, I did a clear cache/wipe and restore I think, I got it to work.
Not sure if this will solve your issue but you can give it a shot...
good luck
I would never flash a recovery from an app unless there was no other option. Use tennear/tenfar tool to flash twrp.

Thanks for your suggestion. I cant wipe/flash/ recover/or even reset to factory because I have no recovery menu at all. Unless there's a way to do that outside of the recovery boot menu.
At least it's not bricked.
