nexus 7 wont react while flashing in fastboot

hello,
today i downloaded the Android 5.0 Image from Google and wanted to flash it.
i extraced the tgz file and flashed the boot.img and system.img via fastboot.
so far so good. i reboot the tabelt and it has a bootloop.
so i used the flash-all.bat included in the tgz file but it wont flash it (didnt copied the error message)
so i tried flashing 4.4.4. but when i flash anything it wont work (fastboot flash recovery recovery.img for example)
i tried differend usb ports and with fastboot devices it shows my device.i tried rebooting the laptop and the tablet. no changes
example
Code:
C:\Users\xxx\Desktop\nakasi-lrx21p>fastboot flash recovery recovery.img
sending 'recovery' (5682 KB)...
after 20 min of waiting nothing changes.
my setup:
a laptop with windows 8.1
all drivers installt
original nexus 7 usb cable
drivers are working fine. i often flashed something on the n7 and my m7 bevor on this laptop

Code:
C:\Users\xxx\Desktop\nakasi-lrx21p>fastboot flash boot boot.img
sending 'boot' (5146 KB)...
FAILED (command write failed (Invalid argument))
finished. total time: 0.001s
thats a error message i get when something more happens then "sending 'xxx' (xxx kb)

Code:
FAILED (data transfer failure (Too many links))
finished. total time: 85.114s

now i managed to flash recovery (TWRP)
but i cant do anything there. in the pc its not listet (adb devices) and in the log of TWRP it says
Code:
E:Unable to mount '/data'
E:Unable to mount '/system'
E:Unable to mount '/cache'
E:Unable to mount '/data'

now i got in TWRP (changing to Clockworkmod Recovery doesnt change anything) and got to Wipe-> Advanced
there i tried to repair the partions . doesnt works. but if i format it that works and could be mounted again. (in system i have to format it in an different file format and back to ext4)
so now i flashed the rom (stock 5.0 from google) and it boots... waiting whats coming next....

i have the same problem how did you format it and did it fix the problem

do you have TWRP ?
you go to wipe-> advanced
there you can choose which repair and format.
ive formated one by one and then it shows the size after formating.
now my tablet booted into android (i think its ugly) but iam afraid going in the recovery

Unable to format in TWRP

When I try to wipe internal it says
Code:
Wiping internal storage -- /data/media...
Error opening: '/data/media' (No such file or directory)
When I try to format instead - I get even more errors:
Code:
Formatting Data using make_ext4fs...
Failed to mount '/data' (Device or resource busy)
Failed to mount '/data' (Device or resource busy)
Unable to recreate /data/media folder.
You may need to reboot recovery to be able to use /data again.

Is this because of encryption? And if so - this is weird because I never encrypted my device. I currently have no OS and just trying to unsoftbrick my phone.

Use fastboot and make sure you are using the latest binaries. Format system, userdata and cache. Upon booting for the first time, the 6P automatically defaults to encryption- unless you intervene and stop it from doing so.

Yep, I just fixed it somehow, I think it was related to MTP in TWRP. However now I'm stuck with a different issue. No matter what I flash in fastboot - I get
Code:

I always get this weird "No error" thing.

Are you sure you are using the latest binaries? Hash checked the TWRP file? Put TWRP img in your fastboot folder? Format/erase recovery partition?

Yes I'm using the latest binaries - I got them via Android SDK and updated everything. I checked the ones you linked and they are exactly the same.
Regarding the hash check - this has nothing to do with the file being corrupted. This happens with ANY file I try to flash.
I tried putting the TWRP img in my fastboot folder and the results are the same.
Erasing the recovery partition gives the same error.
Code:
C:\Users\username\AppData\Local\Android\sdk\platform-tools>fastboot erase recovery

Were you able to successfully fastboot format userdata, system and cache with no errors? Did you get the same error using format as you did erase recovery? Is your phone bootlooping ? If yes, then your phone may have the BLOD. There are a few instances of users still having access to recovery mode, but not being able to flash anything. If you flash a full stock image with flash-all.bat, it finishes but the phone still loops then you likely have the BLOD.

I tried minimal adb & fastboot (bit older version) and got this.
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery twrp-3.1.1-0-angler.img
target didn't report max-download-size

FAILED (command write failed (Unknown error))
finished. total time: 0.007s
Then I tried another old version of fastboot - got one from july 2016 (23.0.1) and nothing happened when executing flash or format commands.
Then I tried normal, latest fastboot and both (new & old) versions of fastboot gave me this error.
Code:
C:\Users\Nexusflip\AppData\Local\Android\sdk\platform-tools>fastboot erase userdata
erasing 'userdata'...
FAILED (command write failed (No error))
finished. total time: 0.023s
Then I tried to format (instead of erase)
Code:
C:\Users\Nexusflip\AppData\Local\Android\sdk\platform-tools>fastboot format userdata
FAILED (command write failed (No error))
I don't know if my phone is bootlooping because I don't have OS installed and my internal storage is squeaky clean. All this crap didn't just start out of nowhere - I flashed 8.0.0 dev preview 2 images through TWRP. I know I'm not the brightest. When I launch flash-all.bat it's just blank and does nothing at all.

It sounds to me like your internal storage (memory) is bad. Bottom line is that if you can't format your basic partitions successfully, you will not be able to flash a full ROM. If you don't believe your memory is bad, you can search the 6P forums for the Qualcomm Flash Image Loader (QFIL) & EDL mode. There is a rescue binary for the 6P floating around that some people have been successful in using restoring corrupt partitions, presumably because it works at the hardware level.

What should I do from now on? I have no idea what to do. The device has been bricked for 24 hours now.
This is the closest I've found to my problem. Also on a Nexus 6P. https://forum.xda-developers.com/nexus-6p/help/zip-file-signature-verification-error-t3561054
I tried adb reboot edl and it says error: closed. So not even that works.

Stock fastboot does not support boot to EDL. You need a modified fastboot, BUT getting to EDL mode won't help you until you have all the proper tools and 6P specific files. I don't want to get your hopes up. I think your device is not recoverable due to a hardware issue (bad memory). If you are looking for a learning project to keep you busy with very little hope of success, keep digging. If you need a working phone, you need to buy another one, or a 6P replacement motherboard from a screen damaged parts phone. Unfortunately, there have been many onboard memory failures on the 6P.

I fixed the problem. It turned out to be a faulty USB-C to USB-A cable. The only problems were with file transfer-related commands. I then tried transferring a 1 kb file, then 1 mb (failed) then 200kb, then 300kb (failed). So it turns out the cable is ****ty. Wow. And nothing is corrupted. I'm typing this from my phone now.

HELP! MLA-TL10 bricked/bootlooped?!

I tried to update stock phone via Firmware Finder from B170 to B360. Downloaded fine and asked for restart. Phone said it was updating but froze at 5% and restarted by itself and bootlooping.
Holding Vol+ and power on leads to "EMUI installing update..." screen, then "Software install failed!" with only option to
Reboot system now
Rebooting takes phone to Huawei eRecovery with options
Download latest version and recovery
Reboot
Shutdown
Download and recovery ends with "Getting package info from server" which eventually fails
I can enter Fastboot & Rescue Mode, but phone is LOCKED (in green text) so cannot flash

Also, the phone is not being recognized by HiSuite latest version (8.0.1.302), and not supported by HiSuite System Recovery!
I've been reading through these forums and Googling but nothing is helping! :crying: Phone is out of warranty as it's a hand-me-down. Are paid options like DC unlocker the only way?

Anyone? Or is this phone too outdated now?

I managed to get microSD card for phone but still having troubles. I put UPDATE.APP into dload folder on root of microSD and boot with three button press but installation gets stuck and fails at 42%. I've tried with all FullOTA-MF roms from Firmware Finder, no success.

if your bootloader is unlocked see this post: https://forum.xda-developers.com/showpost.php?p=74624117&postcount=2

It was locked (getting the 14 day message before) but I tried to unlock again through the EMUI website and it worked!
So I successfully flashed TWRP 3.0.3.0. but I cannot install zips, encountering this error for all versions B360, B358, B356, and B170.

I tried the steps in that post above but there are issues when copying the contents to the device as process hangs at file system.ext4.win000, saying 3 minutes remaining forever, eventually stopping the process itself.
Any further steps? I feel like I am one step closer to unbricking this device though.

i don't know what are you doing like that
flashing official rom is with original recovery not with TWRP recovery
with TWRP you can flash only custom roms like lineage, or restore backup rom
---------- Post added at 12:58 PM ---------- Previous post was at 12:56 PM ----------
and copy backup files to an sdcard with PC, and try the new TWRP

Oh, hmm, silly me then
Anyway, the restore worked fine when put on microSD card. Reboot failed stating an error in Chinese text (don't know what it says), and keeps rebooting into TWRP.
System not booting anyway so flashed LineageOS.zip but during the process, log showed "failed to mount /product (invalid argument)". Reboot phone and it's stuck on Lineage OS boot animation for over 30 minutes
Updated TWRP to latest 3.1.1-0

Changed the filesystem to f2fs and the TWRP backup in that post booted! Everything seems to be working except the phone is branded as CAN.
Flashing any version of stock MLA-TL10 firmware with stock recovery still fails at 42% just like before though. And flashing Lineage OS still hangs on boot animation like before as well.
I think I'll just leave the phone as is in stock Android 6.0, at least it's useable now

Flashed TWRP 3.1.1-0. The log says Failed to mount /product (invalid argument). Never had this error before but everything seems to be working fine.
Just got an idea, if anyone can kindly provide a TWRP backup I can try restoring to that.

i am trying to restore twrp backup but there's a problem
Failed to mount /product (invalid argument).
Failed to mount /cust (invalid argument).
and there's no file name cust and product in offical firmware update.app and any other i had try 3 or 4 firmware's but didnt find any file name in update.app using huawei firmware extractor can you guys please help me out? my phone is stuck on bootloader unlocked option power button for continue col up button for ercovery
my bootloaders are unlocked

Hi guys, some weekend's ago, i tried to relock bootloader (i followed a tutorial), here the problems started...
The bootloader was successful locked, but, i got this message error:
"Data partition damaged ... (i don't remember all)" i decided to unlock the bootloader, reinstall twrp and flash a stock ROM, but, when i try to flash, i got this message error in twrp:
"Failed to mount '/vendor' (Invalid Argument)
Failed to mount '/product' (Invalid Argument) "
I tried to use the tool Huawei update extractor, but when i try to flash system i get:
"target reported max download size of 471859200 bytes
sending sparse 'system' (451240 KB)...
OKAY [ 18.046s]
writing 'system'...
FAILED (remote: sparse flash write failure)
finished. total time: 18.077s"
Thanks in advance...

Did you 'format data' before flashing ?
You should try to install via fastboot the stock recovery then use the dload folder method. That may fixe your problem.

Look another one bricked is phone !

Hi everyone !
As the title implies, i'be bricked my phone ! yay ! So here's the situation in which I am:
- Have access to Bootloader
- Can't flash stock because flashing system give me an error (remote: sparse flash write failure) and flashing cust give (remote: partition error)
- Can't flash custom with recovery because /vendor /version won't mount (with another one but can't remember which)
- Can't dload because I don't have access to eRecovery (trying to flash recovery2 wasn't that good of an idea finally)
I was trying to go back to stock rom but don't really know where it went wrong. I was on Elite Rom V7.5 I believe.
Any help is appreciated !
EDIT: I remember when it went wrong, when I formated /product /vendor /version
