Hi all,
Rooted Nexus running stock 6.0.1 M4B30Z. Phone suddenly switched off and went into bootloop and haven't been able to re-flash stock... bootloader unlocked, fastboot working but no flashing possible (constant flash write error).
I managed to temporarily install TWRP using the excellent NRT v.2.1.9, but still unable to install anything. Seems the problem is storage cannot be mounted with the message 'unable to mount storage'. Again, managed to push the stock ZIP onto the sdcard but can't install.
Anyone got an idea of what it could be? is the device a certified brick now?
Thanks,
Bumping this thread to share steps to solve an identical problem I faced. My Xiaomi Mi 3 W suddenly switched off one evening. It was rooted with TWRP. I had LiveBoot installed. On the initial boot, I could see log data with the phone unable to find/load resources and a "fatal error 6".
I booted into TWRP and found that it could not read any of the partitions. I sense the eMMC memory or the partition table somehow got corrupted. Everything was "0 Mb" in TWRP and wiping or formatting via TWRP was useless -- showing the "unable to mount storage" error.
The OS/data was not in any bootable state at this point.
After an hour of scouring many solutions on Google, the one that worked was: using the "fastboot erase userdata" , "fastboot erase system" & "fastboot erase cache" commands via the ADB shell on Windows.
After this, TWRP could detect my data partition. Cache and System were still 0 MB. But you can fix this by separately reformatting these partitions to "EXT4" via Wipe > Advanced Wipe > Repair/format > Format as EXT4. This was not possible earlier. The error message "unable to mount storage" would have vanished at this point. But you will see "failed to mount system" (invalid argument) for some reason. This isn't a problem.
You'll be able to flash/restore your ROM/backups etc again, now that TWRP detects all three partitions. Sadly, the old data is long gone in this situation. Would love to know what caused this whole issue in the first place.
Thank you !!!!!!!!!!!
IT works!!!:good:
I found your reply by chance after three days of googling around. I was losing hope on my Nexus 5. So far "fastboot erase userdata" , "fastboot erase system" & "fastboot erase cache" worked. Now I'm trying to boot on twrp. If this works you saved me lots of hours.

Still the same "unable to mount storage". Any other ideas?

LOL i was doing the same this days on a Nexus5
The phone was in a reboot loop.
The error i was seeing was "unable to mount \data"
This is how i fixed id:
1. Open the Android Boot select (if this is how is called, the screen where you can select from start, recovery, reboot...)
2. Open the terminal and run "fastboot erase data"
3. After some time reboot the phone

Thanks very much. This solution works for me.
My case is Nexus 5 showing android robot after turning on. Luckily, the bootloader still works so I replaced the recovery with TWRP. Following the format steps and flash system, cache and userdata images again. It's so good to see the Welcom UI again.

Hi guys first thread here and i need your help. Here s the thing, i was using my tf700, browsering, and the tablet goes off, i tried start up and a bootloop appears. So i go to Recovery (latest TWRP) and i tried to flash a ROM (latest crombi kk), like always i tried to wipe cache and dav bfore flash it but that proces seems to fail, and a couple of messages like unable to mount /data unable to mount /system appears, first time happening, i never had troubles with the tablet. So i tried to get fastboot mode and run the fastboot erase cach command (i read in a forum dat some guy did that and work for him), so i download the adb fastboot files, i connect the tf700 to my laptop (windows 7 64bit) and a installing drivers message and i wait and the driver that is called Transformer did not install, i dont know where to get those drivers, i found a file Asus usb drivers and bla bla but when i unzip the file i get 3 folders and no .exe or installer. So i tried to continue and i enter fastboot mode in the tablet and connect usb tablet-pc, and now another driver installing message appears, now is a driver called Fastboot, so i wait anda again the driver did not install correctly. So i continue and open cmd and tried the comman for erase cache, and only appears the WAITING FOR DEVICE text. i donw know waht to do, i also tried flashing again a ROM, bt only bootloop, trie again to wipe cache and dav but is only unable to mount /data. Any ideas ????

More likely your data partition got corrupted.
Try wiping it or formatting /data in TWRP to see if that helps? You will lose everything if you don't have backups.

You'll need to manually format it using the terminal in TWRP
Make sure data is umounted then run this command. Make sure you have charged it as well or leave it plugged in.
It can take a number of hours to complete.
Code:
mke2fs -T ext4 /dev/block/mmcblk0p8

You are welcome!
EDIT - somehow the format finally took.. after 5 or 6 reboots.. very strange
okay, i hate to bump this thread. but i have been searching for a few nights and i cannot find a solution. i am having the same problem as OP.
Essentially, my tablet was interrupted mid format. I believe my data partition is corrupted. I can access recovery/fastboot and the tablet accepts commands from my PC. i have TWRP 2.7.1.1 on the tablet right now.
i tried what sdbags said:

this did not work. i got the same "mke2fs 1.41.14 (22-dec-2010)" output, and then the tablet rebooted back into TWRP over again. (data was not mounted, i cannot mount it at all)
some more output from my tablets TWRP console:
Code:
e:could not mount/data and unable to find crypto footer.
e:unable to mount '/data'
e:unable to recreate /data/media folder/
updating partition details...
e:unable to mount '/data'
e:unable to mount internal storage.
e:unable to mount /data/media during gui startup
full selinux support is present.
e:unable to mount /data/,edia/twrp/.twrps when trying to read settings file.
e:unable to mount '/data'
is there another way to fix my corrupted partition?

and there is also button "KILL" when I hit enter it prompt : /dev/block/mmcblk0p8 is appereatly in use by the system: Will not make a file system here!
Any advice? (sry for being this big noob!)
Code:
adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
reboot
Type in those commands via a usb connection to your device whilst it is in recovery.

Probably a Bad Idea - you should unmount /data before formatting. Then it should also not hurt to keep the recovery running.
Unbrick my TF 700t
Accidentally, bricking my tablet
I try Advance and Terminal Command with TRWP at tablet, it did not work
but when I try with command from PC (desktop), it works like a charm. I was able to see internal storage
from that just re install Custom ROM. Thank alot to sdbag

Solution for 0 MB storage in TWRP
Hi Brothers!
It's my first time posting here , so if i make a mistake i am sorry in advance for that.
Solution for 0 MB storage in TWRP is very easy.
You need to boot your phone into TWRP.
In 2nd step you need to go to WIPE option .
Select Data and click on FS Options e.g. trying to change its partition format, most phones use Ext4.
Do same with the Data.
And TADA!!!!
Your problem is solved
I hope it helps you guys getting answer after a long time because i saw it late. Sorry for that.

Try to wipe everything
Format data using twrp
It should be solved.
Hi my YU Yuphoria 5010 started acting up since last week ,when i noticed that the phone was restarting randomly and the settings was missing and even if i clicked on the settings logo in the notification panel, nothing would happen .So i decided to flash a Cusstom ROM instead and boot into recovery.While trying to wipe cache,dalvik and data I got an error message "uable to mount data,cache ,system(invalid argument) and internal memory* was showing up as 0.So i thought my phone was bricked and tried reviving it with the sd card method.But everything else except for system flashed , and got an error FAILED (remote: flash write failure ) just for system .Anyway now I could boot into recovery using fastboot boot command and the internal memory started showing up correcty. The fastboot command is the only way i could get into recovery, if i try power+volume down it would just come up with the empty battery logo. After this i installed qualcomm drivers and manually changed the driver to Qualcomm HS-USB QD Loader 9008 and tried flashing through QFil with a flashable stock ROM and ended up with the error message:"Download Fail:System.Exception: Unable to download Flash Programmer using Sahara Protocol** at QC.QMSLPhone.Phone.QPHONEMS_SaharaArmPrgDownload(String sFileName)** at QC.SwDownloadDLL.SwDownload.QPHONEMSSaharaDownloadArmPrg(UInt64& version, String armPrgPath)
Download Fail:Sahara FailSahara Fail".
But after going through some of the posts I found that my phone might not be bricked in the first place.My device just shows up as 'Android' under Other devices in Device Manager.
The following are the details from device manager.
Device type: Other devices
Manufacturer: Unknown

I also tried to restore through TWRP recovery using the back up my brother created on his YU 5010A to no success.Changing the file system type and back to ext4 also didnt help. I use a Windows 10 64bit Laptop.
What could I possibly do to revive my phone?Kindly help.

open TWRP recovery.Go to wipe section and select advanced wipe option here .Now select data and cache from check boxes.then click on change partition format.Select ext4fs .Wipe it then wait for sometime because sometimes it takes approximately 15-20 mins so be patient .It will successfully wipe and then you can see that everything is up to the mark !

TWRP --> "Wipe" --> "Avanced Wipe"
Mark only 1 partition at a time and try
"Repair or Change File System" --> either "Repair" or "Change File System" (Most commonly "Ext4" but depends on phone)
What is your specific phone model?

Actually the problem is that the storage is showing 0mb and whenever I am doing anything like flashing other rom or trying to format any of the data ,cache or internal it says unable to mount. Even l have tried QFIL to flash the firmware but it's also failed. Please tell me something.
Is the stock recovery working?
TWRP 3 already tried?
Possible simple solution: but you will LOSE EVERY FILE on userdata.
Step 1: Install TWRP
Step 2: Go to Wipe box
Step 3: Select Advanced Wipe
Step 4: Check "DATA" and tap on "Repair or Change File System".
Step 5: Tap Change File System
Step 6: See original format on file system (EXT4). So turn to other (e.g. ext3) and switch back to original
Now /data is mounted back.
You can also try to erase the partitions using fastboot commands
fastboot erase cache
fastboot erase system
fastboot erase userdata

I have done all these several times and as you have said that change ext4 to ext3 then revert to original. I have done this and it is changed to ext3 but not coming to ext4 again. When I restart my phone then automatically they are changed to ext4.
And yes I have also flashed stock recovery and it is working. But now I am in TWRP recovery.
What should I do now???
Images are attached.

Hi,
I wanted to reset my 510 to a fresh 4.4.4 install. So I decided to "restore to factory settings" within the android system settings menu.
kitkat CM12 4.4.4 by shreps was working fine before, I just wanted to get rid of the data in order to give the tablet away.
now I'm stuck with a soft bricked device, it seems:
- when starting the tablet, the CM screen shows, but freezes after a while
- flashing any CM version in CWM 6..0.5 by shreps shows a "error: can't mount /data"
- wipe cache / data shows the same error
- wipe dalvik cache doesn't seem to respond in any way
- I reflashed CWM 6.0.5 using fastboot flash recovery, but to no success..
what options do I have now? can I format and remount the /data partition via ADB? do I need to go to stock?if, so, how?
Thanks for your ideas!
ok, via
fastboot -w -v
i could reformat the data partition somehow.
I still got an
E:unknown volume for path [/sd-ext]
error, but it continued and works for now.

Glad you dot it going.
I just pulled my 701 out of retirement (broke my Sony z2 screen trying to change my battery) so taking a look in here.
The data format has always been a bit twitchy, but I run the latest version of TWRP for KK. I remember bricking my original Data partition wiping it because some bozo used the wrong partition info making the original recovery for JB. Exchanged the tab.
I recall the bootloader version had to match what version of the ROM you installed (JB, KK, etc), and maybe the recovery also (can't remember). Latest TWRP for KK seems to work for me as I installed Pac Rom before I retired it. TWRP Ver 2.7.1.0
As with the "Path to ext SD", that's always been there if I recall. Just means you have to install a ROM from internal memory. Although my TWRP seems to mount it fine.
But I will say, feels like I've entered the dark ages again.
I have an OP 7Pro (GM1917) that was working fine for a long time with OOS 10.3.8.
I hadn't done an upgrade for a long time, and so recently, I did an upgrade to OOS 11.0.5.1.GM21AA. After doing that, my device is unusable, and I fear that there might be something broken or damaged that causes firmware or storage to no longer function properly. All of the explanatory details follow, and please read all of that. What I'm wondering is whether the device is now permanently hosed, or perhaps if there is some way for me to fix it. Here are all of the details:
After the upgrade, my device went into a permanent boot loop when trying to boot to System.
I then did fastboot boot twrp-3.6.0_11-0-guacamole.img, and it indeed put me into TWRP. However, the /data partition is inaccessible. Whenever I try to format /data, I consistently get these messages:
Code:
Failed to mount /data (Invalid argument)
Unable to recreate /data/media folder.
Unable to mount storage
Unable to mount /data/media/TWRP/.twrps
Unable to wipe data
I go back to the bootloader and connect to my PC, and I then run these commands:
Code:
fastboot erase userdata
fastboot format:ext4 userdata
These commands successfully run with no error messages. I then go back into TWRP, but /data is still inaccessible, and I get the same error messages that I listed above when trying to format /data .
I then tried to decrypt /data, but when I do so, it asks for a password, and I have no idea what password to give. I never used any password on the device in the past. I am not allowed to decrypt /data without a password.
So, I decided to use the MsmDownloadTool to reflash my device back to OOS 10.3.8. This works fine with a different GM1917 device that I have (but which I never tried flashing to OOS 11). However, with this particular device, after going into EDL mode, I am told that I am "Connected", but a couple seconds later it gives me the "Sahara Connection Failed" message. I have double-, triple-, and quadruple-checked the device drivers, and it indeed is showing that the "Qualcomm qds 9008" driver is properly installed and active. Furthermore, as I mentioned, I have no problem using MsmDownloadTool on that PC with another GM1917 device.
I went further: I extracted payload.bin from the OOS 11.0.5.1.GM21AA installation bundle, and I extracted all of the *.img files. I flashed boot.img via fastboot and retried everything that I mentioned above, but nothing has changed.
I then went and flashed all of the *.img files. However, still nothing has changed.
When reflashing the set of all *.img files, in some cases, I was told that the file is critical and cannot be reflashed. I then ran these two commands ...
Code:
fastboot flashing unlock
fastboot flashing unlock_critical
... but in both cases, I was told that the device is already unlocked. Trying to reflash all of the *.img files again gave me the same results: i.e., some got flashed, and others were not flashed due to being "Critical".
Also, some of the items I flashed were said to be "sparse" and their flashes were flagged with warnings, but as far as I can tell, they seem to have been flashed anyway.
Do these problems with /data and EDL and everything else mean that my device is somehow permanently damaged? Or are there perhaps one or more additional things that I can try in order to restore it to some sort of working state?
Thank you in advance for any thoughts or ideas.
This has been fixed.
I had forgotten that in the past, I was trying the OrangeFox dual-boot recovery on this device, and it had repartitioned /data.
I fixed this by booting into OrangeFox recovery via fastboot, and then using its adb sideload facility to flash that recovery. OrangeFox's adb sideload mechanism offers options to the user for repartitioning and rebuilding /data. I utilized those options and set /data back to "Stock", and after that, /data was accessible again.
At this point, I flashed OOS 10.3.8, and then flashed the appropriate TWRP and Magisk, now, my device is back up and running in that OOS version.
The EDL problem continues, but given that my device is now usable again, I am not overly concerned about this MsmDownloadTool issue at the moment. In my spare time, I'll continue to look into that.
All's well that ends well!
I think I also have the same issue but the good thing with mine is my device is still working..but every time I access storage via twrp it give me a 0mb or in accessible data no matter if I enter my password to decrypt data. Until now I just leave it as is for I haven't found any solution
I have the same issue but I can't boot at all. I'm only limited to twrp and fastboot. I was previously running 11.0.3 with Magisk and a Magisk module called xXx_nolimit, downloaded the OTA update and went to reboot to recovery before being prompted for a pattern passcode (I hadn't set any fingerprint or password) so I rebooted into twrp and clicked fix bootloader. Now as I reboot it just boots back into twrp.
I'm also getting these same messages:
Failed to mount /data (Invalid argument)
Unable to recreate /data/media folder.
Unable to mount storage
Unable to mount /data/media/TWRP/.twrps
I'm currently running apbf to bruteforce the pattern passcode that I never set in hopes to decrypt my phone. Not even sure it will work though as I don't have FBE user 0 mounted? I have my dad's phone which basically has the exact setup as mine but I didn't update it yet. Anyway to use partition or parts data from his phone to fix mine? I really don't want to wipe my /data or /userdata as it's been a while since I backed anything up.
Edit:
All I have in my /data folder is:
/data/india
/data/recovery
/data/reserve
The edl issue happended to me too and I just needed to use another msmdownloadtool version.
