[Q] Nexus 7 2013 become a brick (soft or hard?) - Nexus 7 (2013) Q&A

Today my tablet had been frozen and not react to anything. (It was in idle state, I try to turn on the screen, but it remain black) I decided to restart my tablet, but now it struck at the Google logo.
I tried to wipe cache with no success ( imgur.com/QfDObvr)
I tried to make a factory reset with no success. (imgur.com/Wg4Y5sp )
(I am not friendly with android development, but I try to flash a new stock image on it with the guidance of this article:
blog.laptopmag.com/how-to-hard-reset-a-bricked-nexus-7-with-your-pc
But it failed at the adb erase commands because them cant reach the partition too.
The problem look like is the system can not access the cache and other drives, my question is it a hardware error or software error?
Any help appreciated! Thanks!

Make sure you have adb and fastboot working.
download proper image from here:
https://developers.google.com/android/nexus/images
extract the tgz to your computer and navigate to the folder.
plugin phone and put it in fastboot mode
from a terminal run flash-all.bat (if windows) or flash-all.sh (if Linux)
you can edit flash-all to remove the -w if you don't want to wipe your user data.

[Q][help] bricked badly after failed encrypt - fastboot and ODIN can't write to flash

hi all,
i've managed to get my g-nex (vz lte) pretty badly bricked and am hoping that someone here will be able to help. here's what i did initially on the phone:
1. ran 4.0.2 update from carrier
2. installed adb sdk etc on win 7, verified connectivity and function
3. oem unlock
4. rooted phone
5. installed apps, etc.
6. used phone for a few days, rebooted at will, all working as expected, no issues
7. fully charged phone and in the settings kicked off the encryption process, entered PIN, everything looked good.
8. this morning i woke up to a failed encryption (unfortunately i didn't catch the error message) which needed to be rebooted to move on.
9. after choosing reboot, the screen went very strange - it had grainy horizontal lines that shifted in color somewhat and got dim
10. after waiting for a bit without anything happening, pulled the power and battery
11. the phone rebooted into fastboot, couldn't get into recovery to restore cwm backup, couldn't really do anything
phone shows the following:
fastboot mode - no boot or recovery img
product name - tuna
variant - toro
hw version - 9
bootloader version - primekkk15
baseband version - i515.ek02 cdma - i515.ek05
carrier info - none
serial number - XX_redacted_XX
signing - production
lock state - unlocked
here's what i've tried:
adb commands - doesn't show as there from adb devices
fastboot commands - shows up with fastboot devices, flash commands seem to start but never stop
ODIN mode - connects but writes fail to complete
different usb ports/cables, doesn't seem to make a difference
what i've found to somewhat work - but not really do much - is to oem lock and unlock the phone, once there i can fastboot flash boot boot.img, etc. but if i do a recovery and try and boot into it, it just hangs at the google screen (with the lock unlocked).
i would like maybe reformat the phone completely and reinstall, i've tried the fastboot -w and erase boot / recovery thinking that i could write a clean image to them once they had been cleared, no dice.
if anyone has some suggestions, i'd really appreciate it.
take care,
philo
Have you tried a clean install of the factory image found here? http://code.google.com/android/nexus/images.html#mysidicl53f
i have tried going back to factory, unfortunately that set of images didn't work either. i was able (after an oem lock/unlock) to flash the img files, but it errored on the fastboot reboot-bootloader command with the oddly lined screen. i've attached a picture of the screen for reference.

I hope you flashed the LTE version and not the GSM
You need this one https://dl.google.com/dl/android/aosp/mysid-icl53f-factory-65895fa8.tgz and you must first flash bootloader then radio and then the update img
i have been using the lte, same as your link. i can get the bootloader on, but a reboot-bootloader gives that weird screen, if i try and flash the radio without rebooting i get:
unknown partition 'radio'

Check here http://forum.xda-developers.com/showthread.php?t=1392336
Its the cwm for cdma edition.Check if you can flash it and in this way have access to cwm recovery
i've tried that as well, same lines even if i use the menu to go to recovery after flashing rather than reboot to bootloader first.
So long as it's back to stock, and you've locked the bootloader, it's off for a replacement you go if it was me

+1 to this
interestingly, i can't get the fastboot oem lock to take either. it reverts back to unlocked after the reboot fails and i have to pop the battery.
does anyone know how to straight up repartition/reformat the flash? i'm assuming that the failed encryption of the flash has put it into an unusable state and would be happy enough just wiping the damn thing clean...
It looks the encryption screwed up because of the different recovery partition which might of also messed up the partition table.
Best bet is to plead ignorance and get a replacement phone.
problem "solved"
i called samsung and pleaded for the pit + factory image with no luck, so i went over to my local vzw and had them replace the phone for me.
i'm not going to try and encrypt this one, hopefully this was just a fluke and won't affect anyone else...
nice work... let them try to fix that shiz!
Darn, I was hoping for a solution...
I am having a similar issue with a Nexus 5. Phone was working fine, started the encryption process and went to bed and woke up with a bricked phone. I can get into the Bootloader and had figured no problem, I'll just do a factory wipe. Whether trying to boot the phone or get it to do the factory restore it sits there and bootloops with the Google logo. Wish programmers would put in status messages the way we did in the 'old days.'
I was able to get a little further was able to reflash, format the partitions etc. but no luck. I am wondering if perhaps the user data may have an indicator or flag that states it is encrypted even though it isnt at this point encrypted. Figured the factory restore would have been more than enough. WUG makes a nice Root Toolkit that automates a lot of the process but even letting do what I already didnt help.

Yep , if you can get into recovery , you can adb shell , then list the partitions with "cat proc/mounts" , from there you'll have a list of your partitions and you can use the ext4 tools to manually repartition . I believe the command is makefs_ext4 <whatever partition you wanna do > I'll try to find the exact command but you can do it .
Also if you simply type "fastboot " when at the bootloader it'll give you the help text and it should tell you how to wipe partitions from fastboot
Hack The Tuna
The same issue here ! memory locked
I ve got the same scenario on a phone i just got , brand new but with the same issue , this one boots up but its impossible to factory reset it , odin , cyanogenmod , fastboot adb flashes .... everything fails somehow .... once you reboot the phone everything comes back ! stock software with the applications and old data .... theres no way to erase it ... it seems the previous owner of the phone encrypted it and then used clockworkmod or something like that ..... the nand on the device is like hardlocked .... doesnt let you do anything !

[Q] Unbricking One X with no adb?

Hi all,
I tried to install the Jellybean on my One X following instructions step by step from here - the 'guide to installing' link, under the mirrors
http://forum.xda-developers.com/showthread.php?t=1763240
However when booting up it stuck on the flashing crosses for about 20 minutes before I decided it was probably not working. I read the comments and realised the only part I didn't do was a wipe, so I wanted to try again, but before doing a wipe I wanted to make sure I could then re-send the relevant files to my phone via adb, because I assumed a wipe would wipe those files off. However when I do adb devices it doesn't bring up the phone. However if I go into recovery, (CWmod 5.8.4.0) then run adb devices it does bring up my phone on the list. Also when the phone is apparently trying to boot up and stuck on the splash screen loading and I run adb devices it also sees my phone there too. I can send files across. I tried with a recovery img, but the adb message said it was waiting for the device to respond, which it never did.
I had a CWmod backup made before starting, so I ran that, but all that did was change the splash screen it gets stuck on from the colourful crosses to the HTC One logo screen. But it still gets stuck.
Does anyone know what to do from here? I still have access to the bootloader. Do I do a factory reset from the bootloader? Do I do it from CWrecovery? I'm feeling a little bit worried now

First of all take a deep breath. Go get yourself a cup of coffee or whatever your favorite drink is. Preferably non-alcoholic.
In CWM, if you go to mounts & storage and mount your sdcard, you will be able to transfer files to your phone's sdcard. One reminder, reboot your phone to bootloader again after file transfer.
You have to install rom's kernel from your PC using fastboot command (even when restoring from your nandroid backup. Copy the boot.img file to your PC from CWM as I described above)
fastboot flash boot boot.img
fastboot erase cache
As for adb commands, CWM supports adb commands not fastboot commands. You have to use fastboot commands when in bootloader in fastboot usb mode such as
fastboot devices
fastboot reboot-bootloader
etc

Hiya, thanks for that. Just a couple points for clarification. Do I do a wipe first? Or Format? Which wiping option should I go for? There's wipe data/factory reset, and wipe cache partition. Also there's the factor reset option on the first bootloaders screen. And if I do wipe it won't that remove the clockworkmod for recovery?
The rom's kernel... would that be, in this jellybeany case, the file tg_endeavoru-ota-33.zip, and the boot.img file?
I realise these are things I should have learned first, but I thought it seemed rather straight forward, now I'm trying to take no risks so just want to make 100% sure I understand everything involved.
Thanks for your help, knowing I'm not doomed has lifted most of the weight

Since you will be coming back from jb, wiping would prevent any future problems. Even if you decide to stay with JB, do a wipe as below
In cwm,
Wipe cache
Under advanced, wipe Dalvik cache
Under mounts and storage, format system
Cwm will remain intact. Also, I think selecting factory reset from bootloader menu will take you to cwm anyways. It's been awhile.
Yes, it is the boot.img file inside the zip. But you must use the full rom and not the ota. Ota only includes updates to some of the already existing files. It's just an upgrade.

Galaxy Nexus reboot loop flashing error FAIL Exceed Buffer Size

My Galaxy Nexus reboots a few seconds after starting up. I don't have anything other than stock installed and I've tried following several guides here trying to flash it myself since the built-in recovery mode wipe data/factory reset does nothing.
I did notice something strange which following a guide, when I oem unlock and reboot the fastboot mode it locks itself again like I didn't do anything at all. This was a problem when I was using the Android Toolkit too but I managed to over ride my own fastboot oem unlock commands in between its batch file commands and got to an error "FAIL Exceed Buffer Size"
I believe if I can fix or know what to do with that error I can successfully bring my phone back to factory defaults I just don't know what to do! I tried looking for the error on this forum and it came up with 0 results and google isn't helping much either.
I'd appreciate any help regarding this, even if it means my phone is beyond repair I just want to know!
Thanks guys!

best advice,flash back to stock,root the phone,and use bootunlock on your phone to unlock it,it wont wipe your data,then download a recovery.img and flash it with the flashify app,almost everything done with apps and no data loss.

I can't flash the phone to stock because of that FAIL error, and I can't root the phone because it reboot loops before I can enable USB debugging in the OS.

i mean not using toolkit,using actual fasboot. BTW: do you have a custom recovery? if so you could just adb sideload & if you can get the phone into fastboot mode and just flash a recovery then adb sideload after wiping all partitions && did you try using odin to flash back to stock (i dunno if there are odin images available,i apoligize if not)

[2013] Possibly hard bricked on factory image update. Honestly not sure.

Earlier today I used the Nexus Root Tool Kit to flash stock and flash the factory image for 5.0.
At erasing User Data it seemed to get stuck, it was there for over 40 minutes. While looking at the device I accidentally knocked the USB cable out and it said failed. Upon rebooting the device I got the Google logo and the bootloader unlocked icon and then the bugdroid with the gear like it's doing an update (THIS: http://scottiestech.info/wp-content/uploads/2013/03/Android_Update_Screen.jpg[1] ). It stayed like this for another 40 minutes. I forced it to shut down and tried to get into the bootloader but holding down vol up+vol down+power for almost 60 seconds did nothing.
I then booted it up normally again to the gear bugdroid and left it like that before I went out for almost 6 hours. When coming home it was the same and still stuck on that.
I rebooted again and held down to boot into the bootloader but again it did not boot in over 60 seconds.
So am I hard bricked and should toss this out with the trash tonight or can this be restored somehow.
Are you able to connect to your device using fastboot?
Assuming you have fastboot installed and the drivers installed, open a command prompt and from the directory where your SDK files are (unless you added the directory to your system PATH), type "fastboot devices" without the quotes. What do you get back? If you get back a serial#, you should be able to flash the individual files manually
(Download the factory image from google's site, and extract the files into a folder, and run the flash-all.bat This will wipe all your data out, and assumes your bootloader is already unlocked)
Edit: follow the instructions here - http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
These are for Nexus 5, but the same steps apply for Nexus 7 as well. Just make sure you download the right factory image for your Nexus 7. Use Method 1

originally there was none, it just said failed and completed. now i'm getting invalid arguments.
I'm still in fastboot mode but literally nothing will flash.
*edit* just tried to use tookit again and
writing 'bootloader'
FAILED <remote: flash write failure>
finished.
Seeing a couple people mention that they fixed errors like this just from using a different usb port or cable. going to try that.
Why didn't you use adb to flash factory image from the get-go? It's the safest way to flash. I would be so mad on your place if device would render useless. But that might be just me since i'm poor. I really hope you manage to fix it.

I knew of that way but the Nexus Tool Kit has always been perfect and I've never had any issues with it so I figured I'd just do it that way to make it easier and well, it didn't happen.
I'm hoping because I can get into fastboot that it's not actually bricked yet but if so then oh well i guess.

[Q] [HELP] Bricked Galaxy Nexus (maguro)

Hello guys, a friend of mine has a galaxy nexus with some problems.
When I turn on the phone, it starts booting normally, but a few seconds after getting into "desktop" it starts popping up errors saying that the process as stopped.
I've already tried a few things, but without success. I'm running out of ideas and here I'm asking for your help.
Things I've tried:
-Boot into recovery mode and wipe all data.
The phone says that the operation completed successfully, but after rebooting the phone remains the same. All apps, wallpaper, lock screen, etc. It seems that nothing was changed by this process.
-Flash a original google ROM
Following the tutorials, the first step is to unlock the bootloader with fastboot oem unlock. The phone shows a confirmation asking if I want to unlock it, I say yes, and it shows "status: unlocked". But after rebooting the phone it is locked again!!!
I tried to flash the room without rebooting the phone after unlocking it,
Code:
fastboot flash bootloader bootloader-maguro-primela03.img
fastboot reboot-bootloader
sleep 5
fastboot flash radio radio-maguro-i9250xxla02.img
fastboot reboot-bootloader
sleep 5
fastboot -w update image-takju-imm76i.zip
The first command to flash the bootloader also says that completes successfully, but when I'm flashing the radio it will complain saying that the phone has the wrong bootloader version installed.
-Flashing via Odin
It fails when is flashing system.img to the phone
-Flash custom recovery - fastboot flash recovery recovery.img
The process completes "successfully" but when I boot into recovery mode, there is the original one and not the one I just flashed.
-emmc brickbug - partition scanner
I found this thread http://forum.xda-developers.com/showthread.php?t=1823918 and tried to run the partition scanner. As I can't have the phone on enough time to use adb shell, I tried to use this scanner via adb sideload but the phones returns an error when running it. (probably because it doesn't have busybox installed, not sure)
After trying all of steps above, the phone is still the same... nothing changed. Once, I managed to connect it to the pc as an usb storage device, and was able to copy some photos from the phone and deleted them. But after rebooting they were all there again. It seems that all write changes are not persistent.
I'm out of ideas now... Do you have any idea of what is the problem? Or any suggestion for me to try?
Thanks in advance
I believe that there is a script in the android SDK tools called flashall.bat which will reflash the kernel, bootloader, recovery, ROM ect. I'm not sure how to use it, but you could potentially try that
Hi, thanks for you suggestion, but unfortunately it didn't work.
I had a look at the flashall.bat script and it runs the same commands I run manually.
I think that the phone might have some hardware problem... Normally I would buy a new phone, but I'm trying to fix it because it is important for my friend and for me because it is challenging.
I guess that the next thing I will try, will be trying to run emmc_find_brick script by @hg42 via sideload
Try formatting /system and reinstall android. Power your device into bootloader mode. Make sure your device is unlocked. Also, make sure you have the factory image downloaded. After your device is plugged in into your computer, use this fastboot command: fastboot erase system. This will delete everything from /system. Also format /data and /cache: fastboot erase data and fastboot erase cache. After that, try installing the factory image again.
