Unbootable Nexus 7 - Nexus 7 (2013) Q&A

I bought a used nexus 7 off Amazon for a decent price. It's in great condition, looks brand new. The problem is I can't get it to boot up. It goes to a black screen after the boot animation and stays frozen until I reboot. The bootloader was already unlocked when I got it which leads me to believe whoever had it before me was either trying to fix it or screwed it up.
I've tried flashing several different stock os of varying versions via nexus root toolkit v2.1.4 by WugFresh. I can get custom recovery installed, boot into fastboot, and the flashing process seems to work fine until it tries booting up.
It is the 2013 wifi Nexus 7, built in May 2015 which means it's original os and build are 5.1.1 and LMY48G. Not sure that matters too much but I did some research.
Some people with similar issues are saying it's a bad logic board and isn't worth repair but I'd like to explore all other options before giving up.
Any suggestions? Thanks in advance.

Let's see the hardware log:
download twrp-3.0.2-0-flo.img from https://dl.twrp.me/flo/ to your folder with fastboot and adb apps
boot the Nexus in fastboot mode, connect it to your PC
PC run: fastboot boot twrp-3.0.2-0-flo.img
when TWRP is up, run: adb shell dmesg > dmesg.txt
you will find dmesg.txt in your adb folder, zip and attach it to your next post

Check the driver and verify PC connection. As you use WugFresh, then run the commands from WugFresh/data folder.
Option #2
download data.zip to a flash drive
connect the flash drive to your N7 with OTG adapter
boot twrp
go: install/select-storage/usb-otg/data.zip/flash
data.tgz will be saved on the flash drive
attach data.tgz here

[Guide] Re-lock and Un-root **3G & 4G** Xoom

##PLEASE NOTE##
These files are from Motorola's Development site and I take no liability with anything that happens with your device if something goes wrong.
DO NOT ATTEMPT TO FLASH THIS FILE ON ANYTHING BUT THE VERIZON WIRELESS MOTOROLA XOOM Z600 (3G MODEL) OR YOU WILL HAVE A SHINEY PAPER WEIGHT!!!!

You're going to need to have the Android SDK installed. You can download it here:
ANDROID SDK - DOWNLOAD
XOOM Firmware Downloads:
[3G|MZ600-HRI66]
[4G|MZ602-HLK75D]
Unzip the files in MZ600_HRI66.zip and move or copy them to the /platform-tools folder in your SDK folder.
Connect your Xoom to your computer. Type:
Code:
adb reboot bootloader
Wait for it to reboot into the bootloader.
Type the following commands, waiting for each to finish before continuing:
Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot flash userdata userdata.img
fastboot erase cache
You've now successfully flashed your Xoom back to stock. Now it's time to relock the device. Type
Code:
fastboot oem lock
wait for the menu
then press the volume-down button.
Then press the volume up button.
It'll take a minute or so, then reboot. You're now completely back to stock and ready for the update.
So if you are on Three . One you can use this to revert back to out of the box freshness?

Yes. That is correct. This will return your XOOM to 100% stock.
word!
I have already been thru the LNX 0x0004 debacle and it was absolutely no fun whatsoever.
well I got a stuck at moto logo for 10 minutes
I am going to try to fastboot oem unlock, reflash images again and fastboot lock to see if I get out of moto logo

So that means that you got it working, correct?

So the HRI66 is the latest version on the Motorola site? I really need to get a grasp of their version numbers.
EDIT:
Never mind looks like HRI66 is the latest version Thanks anyway.
i was thinking that with the change to the bootloader in the 3.1 update we couldn't use previous versions img's. But I am glad we can return to stock and get this 4G update!
I'm following all those steps directly. Once I type in adb reboot bootloader, it says starting Fastboot protocol support. Once I try to type any other command it says not recognized in adb. Any ideas?

Did you extract all of the files in the ZIP into the 'tools' folder? The same one that adb is in.
Could someone help me,
After the rebooting device I got this massage :
Failed to boot LNX 0x0004
Starting RSD mode 2
Then stuck on Motorola logo. I can't enter the recovery mode.
What should I do ?
My Xoom is H.6.1-38-9 International version

This is what I was afraid of..... try searching the error you are getting. Not many options on how to fix.
i am curious about the LNX 0x0004 error. I know it comes from trying to relock with non-factory img's but what exactly does that mean? I am curious what actually causes the device to soft brick.
Finally I made it, .
I can enter to bootloader by fastboot method, flash the stock image, then relock my device.
Kinda having the same issue as dchurch... "adb reboot bootloader" reboots Xoom to the "M" logo with "Starting Fastboot protocol support," but I can't continue with nay further commands. My computer no longer recognizes the presence of my Xoom and my Xoom doesn't progress past this screen. I can boot it normally with no problem. I've extracted all of the necessary files into my platform tools folder with adb.. any input?

You can try manually going into fastboot as well... there are two ways to do this:
No matter what, power off the Xoom. Then, 1) Power on the Xoom and as soon as you see it turn on (within a second or two of the power on), press the Volume Down button, which kicks it into Fastboot. 2) If you miss the 1st couple of seconds and press Volume Down after 3-5 seconds, it will say "Android Recovery." You can then press Volume Down until you get to Fastboot, then press Volume Up.
My guess is that you have a different issue, something to do with your Fastboot image. Not sure if booting the Xoom into the OS and connecting with USB Debugging on will work or not to flash the files, perhaps maybe just the boot.img?
I also believe that when the Xoom says "Starting Fastboot protocol support", it is in fastboot mode and you can send the fastboot commands to the Xoom. If your PC does not show the Xoom as a device in your PC's Device manager, then you will probably need to load new/correct drivers onto your PC.
Did you make sure that adb recognized your device? Adb devices in the camaned prompt

[Q] wrong twrp won't install kitkat on KF 1st generation

hi all
I have a problem on getting TWRP to work properly.
I initially used BreakDroid to install TWRP, everything worked fine.
I tried to install the cm-11-20140512.1655-SKANKY-otter.zip OS but I first got the "error 7", fixed that, and then it was stuck at "updating package" (or similar)....
then I saw an updated version of TWRP, without realizing that it was for an asys TF101 tablet (http://forum.xda-developers.com/showthread.php?t=2434422)...I installed that and now twrp doesn't work because the screen is the wrong size and I can't get to various buttons including flash/wipe etc..
I can still mount it tho so I thought about using adb/flashboot...but I can't seem to override that version of TWRP.
...best part...i cannot restore the original amazon OS since I didn't do a backup (...i know...:angel
does anyone have any idea about how I can fix that and install a kitkat rom?
I have nandroid backup of stock in my list.

thanks for the reply.
I did look at it but my problem is that I don't need to backup the system, I need to be able to install a recovery tool (twrp or cwmr) that will allow me to flash a rom on my kindle.
my problem now is that I can't seem to be able to do that since the recovery I have is for a different tablet and the screen won't allow me to get to the right buttons...I can only turn the kindle on and off .

2) I installed the img file anyway through

the img file but i still cannot get the twrp with the view for kindle...see attached image. i have NO ACCESS to some of the buttons, therefore I can't do much with it.
I would REALLY like to be able to install a CWM...i tried the one here http://forum.xda-developers.com/showthread.php?t=1454241 using
fastboot flash recovery cwm-file-here.img

but it gets to the boot page, I select "recovery" and then it's stuck with the kindle logo and the small "booting..." at the bottom of the screen...so I re-installed twrp even tho i still have that damn "build for Asus TF101 Series Tablets" (see attachment) warning on top!!
any help would be HUGELY appreciated!!
also, using "adb devices" I still can't see it.
Run this command from your computer with your kindle connected when you turn it on:
fastboot getvar product
The FFF bootloader temporarily enables fastboot as the device boots up. When you issue this command, it puts the device into permanent fastboot mode. Just flash the correct recovery after that:
fastboot -i 0x1949 flash recovery your-recovery.img
fastboot reboot

When I launch the fastboot flash in fastboot mode I do get nothing but the blank cursor on a new line, although I see the device with "fastboot devices". After a few min that was stuck then I turned it off and the first part came up saying " sending file" but then it gave me an error saying that the connection was lost...which makes sense cause i turned it off..
If instead I launch the command and THEN turn the kindle on it does show me the correct output in a couple of secs as your showed. But then even if I do fastboot reboot, it does reboot it but no correct recovery is loaded...still the wrong screen size... Very very frustrating...
And btw...thanks for bearing with me through this!!!
---edit---
Now that I think about it...the twrp screen, although the wring size, actually reflects the VERSION of twrp that I'm installing through fastboot...it's as if the twrp I got from here ( http://forum.xda-developers.com/showthread.php?t=2434422) controls the size of the screen while I'm able to change the version of twrp...I think that that is a recovery GUI for the Asus tablet, any idea if I can install another GUI?...hopefully this helps...

Your guess is right, installing another TWRP version doesn't affect the theme you are using, unless it has a theme of its own. You could delete the ui.zip from the TWRP folder and that would solve it. The folder should be in sdcard.

so..the problem with that is that I could not access the sdcard since adb doesn't work...however...as of now I've been able to fix the layout problem by using
fastboot -w
fastboot flash recovery twrp.2.7.0.1.img
fastboot reboot
Click to expand...
Click to collapse
once rebooting I had to re-wipe (advance wipe) sdcard/cache/data since when I tried to mount them I could not check the boxes.
now i STILL cannot mount it and adb does not recognize it.
I'm using mac and I tried
android update adb
Click to expand...
Click to collapse
but still adb can't see the kindle and I can't mount it through twrp
...however, I'm still able to reboot in bootloader and use fastboot
I don't think I can flash a .zip rom from fastboot tho...and I'm not sure how to transfer files on the kindle to flash them from twrp...any idea?
thanks a ton!!
-- edit --
i already modified the ~/.android/adb_usb.ini file adding 0×1949 and then running
adb kill-server
adb devices
but what I get is just
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
and nothing to it...the "adb shell" still gives me "device not found"!!

dunno why twrp was the problem! the new recovery that you linked worked like magic, adb worked perfectly, I already flashed a rom and it works!!
so...why wouldn't twrp allow me to use adb or mount disks through usb?!
thanks so much for the help!!
Guessing it doesn't use the twrp theme, that was causing trouble.

Attempted to root, maybe bricked, can I recover?

Last night I attempted to root my Fire 8.9 2nd gen.. I used a video on youtube to follow the procedure (not sure if I can link it here? if so, let me know). I managed to get twrp installed, but when it rebooted it got stuck on the kindle fire logo. The color of the text "Fire" changes from Orange to Blue on boot and stays that way. I can turn it off and then back on, and hold volume up to get into twrp. Problem is, when I say to mount storage, or connect it to the computer, nothing happens, so I'm in this limbo where I can't recover back to stock or install a ROM.
Maybe I'm not doing something right when trying to mount the internal storage? I've tried on Windows 7, OS X "El Capitan" and an Ubuntu variant.
I don't have a factory cable, just the cable that came with it.
Thanks for any help!!

Does adb recognize your kindle when it's in TWRP? If it does, then enable sideloading in TWRP (under the advanced menu) and try adb sideload /path/to/ROM.zip to flash a ROM.

Thanks for the reply. Sort of.. If I boot it to fastload or fastboot, w/e it's called, I can open adb shell, but the prompt is odd. If I try to su , it won't work. If I boot into twrp then do adb sideload, it just doesn't work at all.
The computer sees the device though, fortunately.

No adb drivers are needed for Ubuntu - you just need to make sure the android-tools-adb and android-tools-fastboot packages are installed (you'll need the 'universe' component enabled in the "Software and updates" settings to install them via apt-get). The kindle doesn't have an external sdcard, so you wouldn't be able to use a removable one. If you're trying to wipe/format the internal sdcard and other partitions, use the Wipe -> advanced wipe menu in TWRP.

If you have the # instead of the $ in the terminal, that means you're probably authenticated with root already. In that case, do apt-add-repository universe && apt-get update && apt-get install android-tools-adb android-tools-fastboot - this will automatically enable the universe repo, update the list of available packages, and install the adb and fastboot packages if they aren't already installed.

Sorry, I should've been more clear. I've added in the universe repository, and installed android-adb-tools as well as android-tools-fastboot. When I said I have # at prompt, that was after typing adb shell. It seems to let me browse through the tablet, a good indicator it's connected and working. My apologies!
Now that I have connectivity from my linux box to the tablet over usb, what are the next steps to recover it? If I type adb shell <enter> whoami, it says root. So we have root access to the tablet. Yay!

Exit adb shell if you're in it already. Now in the linux terminal, type adb push /path/to/ROM.zip /sdcard, where the /path/to/ROM.zip is where your CM/other ROM zip is located on your PC. Repeat this process for any other zips you desire to flash, like xposed, gapps, etc. This should hopefully put the files in the internal storage, from where TWRP can find and flash them. Good luck!
(Side note: assuming you can boot into TWRP, you should be able to view & manipulate the kindle's internal storage from Ubuntu with nautilus or another GUI-based file manager.)

CyanogenMod has somewhat stable CM12.1 nightlies available for download here, although I think they're starting to slow down now. If you wanted to flash back to the stock OS, Hashcode created a ROM zip for Amazon OS 8.4.1 (the 8.4.3 version was hosted on the now-defunct goo.im), and you may find the link in this thread. That particular version is a bit outdated, but it shouldn't be too hard to manually upgrade.

Try updating your TWRP. Here's Hashcode's thread that links to a download for the latest version (2.8.7.0 as of the time of writing). It's a .zip, so you can flash it in TWRP.

Thanks. I was able to update twrp and get the 23rd of Dec's nightly CM12 build installed. It didn't seem to work properly though, and gapps wouldn't install. So I've resigned to the fact that I need to put the original OS back on it. After updating twrp, this doesn't seem possible. When I connect it to the computer, all I'm getting is error: device offline when typing adb shell. This is in linux and windows.
I tried connecting it and mounting the usb storage, then dragging over the fireos images, but after installation it went into this reboot loop due to a corrupt something or other... Now, I can't get cm or the original os back on it.
So, some updates... it's still dead.. but here goes:
I tried to copy the original os as found in the link you gave above to the fire via the usb storage mode, but after install and reboot it keeps failing as I mentioned due to corrupt data (the amazon os is throwing that error). so I tried adbsideload... it kept telling me that i needed 1.0.32 or newer of adb. After obtaining that, I was able to sideload the original OS image to no avail.
So I tried the recovery tool: KFHD System.img Recovery Tool but I used the wrong one (the one that isn't for 8.9 inch fire hd tablets)... and now it's stuck at the fire logo (orange/yellow in color). Turning off on again and holding volume up to get to twrp no longer works as it's been de rooted, I believe.
Any suggestions?

The volume up to enter TWRP no longer works because the bootloader's been returned to stock. Regardless, you should be able to boot into fastboot. First, make sure the kindle's turned off completely and not plugged into your PC. Then type fastboot -i 0x1949 getvar product. When you see <waiting for device>, plug the kindle in. The kindle should now show a fastboot screen, and the terminal will have outputted a string looking like "Jem-PVT-Prod-04". At this point, if both of those are true, then you should either locate your backups of the stock software or download it for your device. If you haven't made backups, then you can try this tool to attempt to restore. If that tool doesn't work, I have a backup that I'd be willing to share if necessary. In any case, once you have the stock system images, you should flash them as instructed by Hashcode here (skip to the "Flashing back to stock" section). Good luck!

Thanks for the reply. Surely I must be overlooking something.
I downloaded the kindle fire HD recovery tool from the link you provided (the post by onemeila) - KFHD_SRTv2.1-8.14. Opened the SR Tool file, and used option 2 to restore su and such. When it rebooted, nothing happened... stayed stuck on the orange kindle fire screen.
Next, I obtained the boot and recovery img files from the KFHD System.img Recovery thread by onemeila, and put them in the root of the KFHD_SRT_v2.1 folder. I also copied the system.img that comes with the KFHD_SRT_v2.1 file to the root of it, instead of the folder I was in. Then I issued the kindle the following commands from an administrative command prompt... there weren't any errors:
fastboot -i 0x1949 flash boot boot.img
fastboot -i 0x1949 flash recovery recovery.img
fastboot -i 0x1949 flash system system.img # This one will take a few minutes
fastboot -i 0x1949 reboot
It rebooted, but has remained stuck on the orange kindle fire screen.

Do you have adb installed system-wide? If you do, try cd'ing to the directory where you placed the boot, recovery, and system images and then running those commands again. If you don't, then move the files to the folder where the adb and fastboot executables are located and run the commands in that folder.

Nexus 7 WiFI 2013 (Razor, FLO) CyanogenMod Recovery only...

I have a nexus 7 WIFI 2013 (Razor, Flo):
I was trying to get a copy of Nethunter or Kali linux installed on here. I was running CyanogenMod nightly's
Well during one install, I must of wiped the whole tablet clean. It only had dad/media and then subs /0, /obb folders. I'm unable to find any images on the card and nothing else is displayed. I have tried number numerous drivers for my Samsung laptop but when i use my surface it shows nexus 7 and also when i go into bootloader mode it will also show the driver.
I installed droid SDK and also minimal adb and fast boot. I'm unable to push anything to this device. When i run adb devices it shows the device but says unauthorized. I try adb kill-server and adb start-server and still no dice.
I'm looking for any input as to how I can push and image onto this device. I realize I will have to go back to factory and I have all them images. I just cant get it adb authorized yet.
this will only go into recovery mode and boot loader mode. There is no OS if I let it boot it just shows the mod logo and will sit there until the battery dies.
Does anyone have any input on how to get this authorized so I can push files to it. I'm unable to get on the screen and ok the RSA fingerprint and I think that maybe part of my hold up or why it shows unauthorized.
Thanks in advance for all or any input or ideas.
Start TWRP and it will authorize you to push any files anywhere.
I'm unable to get TWRP on this tablet. The main issue is I only have cyodgen mod recovery on the tablet. It will not boot. It will only go into recovery mode/bootloader mode. I'm unable to verify any RSA fingerprints which is causing me an issue getting the tablet authorized for ADB pushes. Does anyone know a way I can get it authorized via ADB without being able to access anything other then recovery mode? I think the RSA fingerprint is whats actually causing me an issue.

No need to flash TWRP - just start it directly from RAM:
download twrp-3.0.2-0-flo.img to your folder with fastboot and adb apps
boot the Nexus in fastboot mode (when off press power+vol.dn), connect it to your PC
on PC run: fastboot boot twrp-3.0.2-0-flo.img
when TWRP is up, ADB-push your files, no RSA concerns

ADB and fastboot cannot detect the phone

Hello, I have two unlocked Pixel 2XL, one works without a problem, it is detected by adb and fastboot. The second one during boot has bootloop. When I try to turn it into fastboot mode, the screen of this mode is shown, but after connecting the cable (which works on the first fully working phone) and entering the command "fastboot devices" nothing happens. In device manager I only have 'device not detected or working incorrectly (code 43 or sometimes code 10). When trying to enter TWRP, the phone completely stutters and displays only the TWRP start screen without any other symptoms. I have good drivers installed because the computer detects this working phone without a problem ... Do I have a damaged USB port on the phone? Is there another explanation and solution for this?

Most likely the culprit is either out of date platform-tools or TWRP...
What version of adb, fastboot, & TWRP are you using? Also, how are you booting TWRP -- there have been many cases where people would use the command "fastboot flash boot twrp.img" instead of booting temporarily...
Hope this ends up being helpful as that means it resolves it...
Are you able to fastboot boot the latest twrp.img?
Might want to give Deuces script a whirl. I've seen this fix situations like yours.
ADB version: 1.0.41 29.0.5-5949299, TWRP: twrp-pixel2-installer-taimen-3.3.0-0 Latest Rom istalled on this phone is Havoc OS 2.8 for P2XL. I trying to enter TWRP via fastboot and choose recovery there, but stuck on TWRP logo... When I try to enter a command: "fastboot boot twrp.img" receives a message: <waiting for any device>
edit: Deuces script log says: "Welcome to Deuces Flashing Script!

This might sound crazy, but, at least try another USB A to C cable, and other ports on your pc. The P2XL is notorious for being finicky when it comes to cables and ports. What might work for one phone, doesn't necessarily mean it will for the other. Make sure it's a 2.0 USB cable as well :good:
I checked four different cables and all ports on my computer and still not lucky... I even checked on another computer and still the same

Then it's likely a hardware/port issue would be my guess.
Meh, so I will look for a workshop nearby that will exchange the port for me and check later
I would also suggest that you re-download EVERYTHING...
You may be stuck with a "buggy" TWRP image file or platform tools....and/or go against conventional thinking and download and try an older version of TWRP to see if it does it at that point as well...
In either case, hopefully you get it figured out and good luck to you...hope this ends up being helpful!
There were a number of Pixel 2 XL's that did suffer from charging port issues, including my original. Luckily I was still under warranty and was issued a replacement. The phones would charge fine but data did not transfer as with adb/fastboot, nor would Android Auto work.

Platform-tools are up to date?
Did you open your command prompt directly on the platform-tools folder?
When you typed in "fastboot devices" did you see your device ID Number?
Are you using a 2.0 USB A to USB C cable?

Not running platform-tools through power shell either are you?
What happens when you try double clicking on the flash-all.bat file with your mouse?

Based on your error, I'm guessing all the files in the Full Factory .zip file (all 6 of them) aren’t residing there with the adb & fastboot .exe files within the platform-tools folder. Make sure you’re seeing those 6 files (you will have a two .sh files, two .img files, one .zip file, etc.) with the .exe adb & fastboot file.
Then, also make sure that you are directing your powershell or command prompt to the correct “platform-tools” folder, because many other people seem to have multiple “platform-tools” folders and they end up directing to a wrong folder…
Hope this ends up being helpful…
I fixed it! The error in fastboot mode probably came from a file that I extracted from winrar, when I downloaded the factory image again and extracted the files this time through 7zip and copied them to the platform-tools folder and double-clicked flash-all.bat fastboot started and the installation was successful! Thanks to everyone who wanted to help me solve this problem <3
ps. btw, I haven't replaced this broken port on the phone... just started working again...
