[Q] Can't boot after unlock and root

Wanted MIUI V5 on my Nexus 4 and tried doing it through unlock and root. Now I have apparently unlocked and rooted I can't boot into Android (stays on the X animation for >10 minutes) and I can't factory reset through recovery.
After installing the Android SDK I tried to unlock through fastboot.exe using the command "fastboot oem unlock" (from here http://www.youtube.com/watch?v=ywaMf29yExQ). It unlocked, I installed a recovery menu using the command "fastboot flash recovery openrecovery-twrp-2.4.2.1-mako.img" and when I booted into it it asked for a password. I used my phone pin but it didn't work so I just skipped it.
After this the phone wouldn't get past the X animation when trying to load the OS so I tried using the Nexus 4 toolkit (from http://forum.xda-developers.com/showthread.php?t=1995688) to install stock android 4.2.2 and it didn't work.
This is my first time into Android DIY so please avoid getting too complicated.
Any suggestions?

Flashing the stock rom using the toolkit didn't work? You mean you couldn't flash it or you could flash it but it still doesn't boot?
By the way I wouldn't recommend to use any toolkits. Better read and understand and flash everything one by one to avoid problems

Follow the directions in the guide at http://forum.xda-developers.com/showthread.php?t=2266654. I would recommend TWRP 2.5.0. You will need to transfer the MIUI ROM and Gapps files to the Nexus internal storage using adb. Download the ROM and Gapps at http://forum.xda-developers.com/showthread.php?t=2327158. Boot your phone into recovery, connect the USB cable from the Nexus to your computer, and transfer the ROM and Gapps files from a command prompt opened on your computer in the folder on where you have installed adb and fastboot using the command "adb push mako_miui_3.8.23_Stock+r165.zip /sdcard/mako_miui_3.8.23_Stock+r165.zip" and "adb push ROM.zip /sdcard/ROM.zip" followed by "adb push GAPPS+EXTRAS_V2.zip /sdcard/GAPPS+EXTRAS_V2.zip". Finally, use TWRP to wipe the system, install miui_3.8.23_Stock+r165.zip followed by GAPPS+EXTRAS_V2.zip, clear the cache and Dalvik cache, and reboot the phone.

Try flashing stock manually. Follow this guide.

It didn't work because you didn't download superSU, if TWRP asks for a password its because SU wasn't in the storage of the phone. Furthermore always download the latest recovery which is 2.6.10 I believe. Also if you get into a bootloop (stuck at boot screen) go into fastboot and write in SDK 'fastboot erase cache' and if that doesn't work 'fastboot erase userdata'. As you messed up install the nexus factory image and do what you did before but with the corrections I have suggested.

[Q] Google nexus 7 (2012) - Unrooting leads to total failure(no recovery, no boot up)

Dear developers and other users!
I have been looking for same issues but I was unable to find answer for my problem.
About a year ago I unlocked and rooted my nexus 7 tablet to use special apps on it.
Today I tried to unroot and lock my device. On my laptop the program(Nexus Root Toolkit) said it was successful so I just needed to reboot the tablet.
After rebooting it stopped on the Google screen with a "Booting failed" text on the top left corner like that:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I think I have uninstalled android from the device but I can't Intsall a new one because recovery mode doesn't work and Android is not going to boot.
I can only use Bootloader. Bootloader looks like that:
Once I started my tablet it started in bootloader mode but every other startup fails on Google screen.
Please help me to use my tablet as before without root.
What should I do and how should I do that to get it work again?
Any help would be highly appreciated ​

You don't use USB debugging or adb in fastboot to flash the factory image. Follow the link and read the instructions carefully.

Its much easier on a Linux machine. All you need to do is open terminal and type "sudo apt-get install android-tools-adb android-tools-fastboot" and hit enter. Then extract the .tar file and double click "flash-all.sh" and choose run in terminal. Absolutely no driver headaches.
If you have access to a Linux machine (mint/ubuntu) or if you can dualboot Linux, this will really help

I too have this same issue...
Exception is my Nexus is locked... everytime I try to unlock it, it tries to reboot and never comes back on...
What am I doing wrong?

Thanks for everyone I successfully made my tablet work by flashing a stock android 4.4.2
The solution:
1. I connected to my father's laptop (with Win7 on it and mine had Win8.1 so you MUSN'T try fixing on Win8.1 because of the drivers) because my laptop detected the device as undefined USB component and my father's laptop showed the tablet as Nexus 7.
2. I found a working adb&fastboot here
3. After the download is done unip the file and run RUN ME.bat and type fastboot for help
*If needed after running the RUN ME.bat file type
fastboot oem unlock

(this will unlock your bootloader which is necessarry
for the following steps)
4. After reconnecting my device and booting to bootloader mode and downloaded the new firmware (unzipped into the fastboot folder) type fastboot
fastboot update image-nakasi-kot49h (this was the firmware that I needed to "update")

5. After the fastboot started working and flashing the new OS (it takes about 5 or 10 minuntes) the tablet will restart and starts optimizing all te apps that you had before (that happened in my case).

I was hopeful that this would work for me.... I am using a win 8.1 machine and the downloaded fastboot and adb seemed to work fine.
I go to do a fastboot unlock and I get the following:
(bootloader) erasing userdata...
(bootloader) erasing userdata done...
(bootloader) erasing cache...
(bootloader) erasing cache done...
(bootloader) unlocking....
FAILED (remote: (Unknown error code))
finshed. total time: 7.902s
So..... Anyone ? The tablet does ask if I want to Unlock the Bootloader... I select yes and hit the power button to select... yet the tablet goes back to the android screen... The top of the screen says Unlocking now...... yet it doesn't...
Please help...

4.4.2 to 4.4.4

Not sure what happened here with this freaking thing. I followed the instructions located here. I grabbed both the 4.4.2 and the 4.4.4 located here.
I applied 4.4.2 to go back to stock and the tablet didn't make it past the Nexus boot logo. So, I rebooted into the bootloader and then flashed 4.4.4 thinking there was an issue.
Same result. Still no boot.
Any ideas? Of course I didn't back squat up because I did this same exact thing on my Nexus5 and it worked flawlessly. So, I figured, why back up anything because it will work the same on this tablet.
No clue what the %&@(&% happened.
I also can't get into Recovery mode either.

How did you flash these update with fastboot?

Yup. Copied all the files in the factory images to "platform-tools". Opened a CMD prompt window and then typed "Flash-all"

If using windows is the file called flash-all.bat ?
make sure if you are using windows that your CMD window is opened as Admin....
Can you do this again and post the input and output of the process here ?
Thx Josh

Yes Sir, I am.
I've done this:
Proceed with this step if you want to keep your data intact. If you skip this step, your data will be wiped. With your favorite text editor, edit (be careful not to run it by accident instead of editing) flash-all.bat (if you're on Windows) or flash-all.sh (Mac, Linux) and remove "-w" from the fastboot update command. For example, if the line reads fastboot -w update image-razor-jss15j.zip, it should now read fastboot update image-razor-jss15j.zip. The -w option instructs fastboot to wipe data.​Which worked flawlessly on my N5 "upgrade".
I am an Admin user on this machine so the CMD prompt is Admin.
There are no errors either in the CMD prompt window or, the Tablet. Everything appears to transfer over without any issues / errors.

Can't sideload anything (No rom installed; Tried everything)

Hello people, basically I'm experiencing a problem in which no ROMS will install and I have nothing on the phone itself to fall back on (all partitions wiped.)
I'm using the latest drivers, but the phone has a problem receiving commands via the bootloader for some reason. I've tried side-loading, flashing a zip normally, using the "Flash stock+unroot option" all via the "Nexus Root Tool-kit"; I've tried using the command prompt through Android SDK's ADB flashing tool, but it didn't work.
While trying to side-load via the Nexus root tool-kit it doesn't work, however while sending the command to boot into stock recovery it does show "downloading..." text at the bottom of the screen, but it freezes up and I have to hold power+volume down to get back into the bootloader successfully.
While trying to side-load via the command prompt through ADB side-loading (SDK) however, it recognizes my device and tries to install zip files but says at 1%, 2%, and 4% (depending on the file) and nothing really happens and after I cancel the sideload it says "can't open /tmp/update.zip (bad)", I then tried finding an update.zip file for the recovery but that didn't side-load either (nor TWRP; my preferred recovery)
This all happened after I stupidly downloaded+installed a previous version of CyanogenMod in which afterwards no processes would work, so I factory reset it and nothing's working (here I am.) Early on I hit root on the clockwork mod since it said it wasn't rooted (I hit it anyway, hence it already being rooted), that may be why I can't do anything in the first place (I did this before I even tried flashing a zip); I then wiped all of the partitions this morning, and no changes. I've also tried all 3 drivers for the Google bootloader (Naked drivers)
I'm using Clockwork recovery 6.0.5.0 legacy (non-touch) and have a Nexus 4 that's unlocked+rooted.
Please help, I've tried everything and have spent hours on end with Google searches and troubleshooting to try to fix this.

I have similar problem, so maybe not generating new threat...
I got OP2 from friend. He used Oxygen 2.x (don't know exactly) and decided to flash some custom ROM. And something went wrong
He brought me today his phone and:
- fastboot works,
- device is locked and impossible tu unlock (FAILED (remote: oem unlock is disabled))
- after 2 hours of work I got stock recovery working (using some Chinese Qualcomm recovery tool).
But: I can't unlock BL, I can't flash anything via fastboot (because ->locked), ADB doesn't work too (cant push any file to devices).
When turning on phone it's in bootloop, but I can enter fastboot or stock recovery.
I tried almost all solutions from her and OP forums, but everything false because of locked BL.
ANY ideas? My short knowledge ends here There is probably no any data in device (no system, userdata etc.).
I don't have USB-C pendrive / cable so I cant flash anything from stock recovery. If I'll get USB-C pendrive will it be possible to flash stock ROM with stock recovery?

I tried but with no success. All this tools works flashing .img's from fastboot. It's useless for me...

try this...... "fastboot -i 0x2a70 oem unlock-go"
worked for me

Thank, but :
C:\Android_sdk\sdk\platform-tools>fastboot -i 0x2a70 oem unlock-go
...
FAILED (remote: oem unlock is disabled)
finished. total time: 0.007s
Same...

It sounds like the ability to unlock the bootloader is disabled in developer options. I think, but I'm only guessing.

Yes, but I can't boot to system (probably memory is empty- no data) and switch OEM Unlock.
I've got only fastboot and stock recovery.

do any of these help you? I guess you could say your phone is hard bricked due to not booting to OS and not having TWRP recovery?

I used this tutorial but I can't get device correctly installed as Qualcomm. I'll try on other pc.

I have similar problem, so maybe not generating new threat...
I got OP2 from friend. He used Oxygen 2.x (don't know exactly) and decided to flash some custom ROM. And something went wrong
He brought me today his phone and:
- fastboot works,
- device is locked and impossible tu unlock (FAILED (remote: oem unlock is disabled))
- after 2 hours of work I got stock recovery working (using some Chinese Qualcomm recovery tool).
But: I can't unlock BL, I can't flash anything via fastboot (because ->locked), ADB doesn't work too (cant push any file to devices).
When turning on phone it's in bootloop, but I can enter fastboot or stock recovery.
I tried almost all solutions from her and OP forums, but everything false because of locked BL.
ANY ideas? My short knowledge ends here There is probably no any data in device (no system, userdata etc.).
I don't have USB-C pendrive / cable so I cant flash anything from stock recovery. If I'll get USB-C pendrive will it be possible to flash stock ROM with stock recovery?

Fastboot this, it will DELETE EVERYTHING(no exceptions) (maybe except firmware) and install seraph08's cm13.

or flash stock OOS2.x official via stock recovery(if MTP or ADB works in stock recovery)
No idea about USB OTG, try dont buy. Might work in TWRP, dont think itll work on stock
or try the soft brick recovery on his basketbuild or other various available threads
Edit: you said fastboot works and then you said it doesnt work, confirm.

I used other PC and other tool including system.bin and userdata.bin. And it finally worked. Unbricked
