Bootloop + E:unable to mount /data

Moderator Notes: I was asked to sticky this thread as it seems to be a recurring issue and a couple of fixes are in the posts.
Sorry my bad english am latin.
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.

i already tried that, wiping (cache, dav, system, ata, factoty reset) anything gives the unable to mount /data error.

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

[Q] One not visible in PC after SDcard format in TWRP

Hi,
I decided to upgrade to AICP after 8 months on SlimKat today.
So, I choose full wipe (Cache, System, Data, Dalvik and SDcard too) as I wanted to clear SDcard data too.
But TWRP (2.8.6.1) ended up with error 255 during wipe. Also TWRP format /sdcard ended up with error 255.
Then I pushed to One following files via adb:
- OnePlusFirmware-20150523.zip
- aicp_bacon_lp-9.0-NIGHTLY-20150616.zip
- Slim_zero_gapps.BETA.5.1.build.0.x-20150612.zip
- SuperSU-v2.46.zip
1) FW installed OK
2) AICP + Gaps + SU installed OK
3) restarted
One boot up OK, I setup everything, but One is not possible to see in PC (W7) - not as MTP neither mass USB
What to do? How to fix this?
Thank you very much...

Try the following
1.Reinstall the One Drivers again.
2.Go to device manager (right click on My Computer) - - USB controllers - - Uninstall USB Hub - - Scan for hardware changes
3. Install multirom and flash CM11S and check whether it's getting detected from KitKat ROM.
I had simply downgraded to CM11S as I was facing this issue with screenshot issue

I tried that one already. Problem is that PC does not even recognize that I connect One to the USB
It is like I did not connect anything... but One is charging OK
Edit: what is very strange is... when I trying to wipe "Internal storage" I got an error:
>>> "Wiping interna storage -- /data/media...
E:mount -o bind '/data/media/0' '/sdcard' process ended with ERROR=255"
That might be the issue, but I have no idea how to fix it
So, no I cannot install SlimKat back...
I push there ROM:
c:\aaa>adb push Slim-bacon-4.4.4.build.9.0-OFFICIAL-8300.zip /sdcard
6674 KB/s (171562038 bytes in 25.100s)
But when I tryied to install it in TWRP... I got this:
Format and Mount System, Mount Data...
Symlinks and permissions...
Flashing Boot Image...
script succeeded: result was [/system]
Updating partition details...
E:mount -o bind '/data/media/0' '/sdcard' process ended with ERROR=255"
...done
E:mount -o bind '/data/media/0' '/sdcard' process ended with ERROR=255"
Edit: when I connect One to the PC, it start charging, but it does not show up in USB devices at all
Issue fixed
Issue fixed by: Settings > Developer Options > USB Debugging > uncheck the tick-box :good:
It seems like the LP use the "USB Debugging" different way the KitKat, but it One was normally visible in PC with this option switch on :angel:

Strange. I have that option enabled all the time and the PC recognizes my phone, but it os good it worked for you
USB debug
Seems like the BlissPop on the OnePlus One works different way
If I disable "USB Debugging" and then connect One to PC, SD is normally visible and accessible.
When I enable "USB Debugging" (One still connected), the SD card is disconnected (disappear from My PC).
I "need" this for TB only anyway and even if "USB Debugging" is disabled the TB works, so no prob... :angel:
At least I know how to "fix" this :good:

How Can I Get Out of This Bootloop on My Moto G

I woke up to find my 1st Generation Moto G battery was depleted and on charging it a bit., I switched it on only to find it optimizing my apps. All these (battery getting depleted, app optimization) happen all the time and I wasn't the least worried.
I picked up my phone later thinking it must have been done with the app optimization only to discover it was totally dead while still connected to a power bank. When I try to switch it on, it is stuck on the "Unlock Bootloader" page. I have tried flashing a new stock rom and it does not work.
I attached the image I see when I try to use recovery to wipe. Basically, nothing works. Can anybody help as I just fixed the screen and also out of warranty?

Via PC, do the following wipe: (requires working ADB setup)

You could then TWRP > Wipe > Format Data > Yes, and try flashing a custom ROM.

Recovery mode ADB will work with Linux - unsure about Windows. You could boot into an Ubuntu LiveCD (without installing) and transfer the ROM to phone that way. Otherwise, an OTG usb pen would be another option.
adb push rom.zip /sdcard​
@lost101, I tried to send the Rom via ADB and I got : failed to copy 'Rom.zip' to '/sdcard//Rom.zip' : Read-only file system.
Also, TWRP made my phone to load as MTP on my PC but I could not transfer through that method also. The transfer kept on failing. Seems my internal memory (eMMC) is now Read-only.

is corrupt, and you might try running e2fsck with an alternate superblock:

A certain percentage of phones end up with corrupt emmc (internal storage) over time. This problem is a fairly common thing. I do recall someone managing to boot an use CM13, despite the read-only userdata. I'm guessing they must have flashed it via TWRP, with the ROM.zip on an OTG usb pen. It may have worked because /system was still partially / fully writeable.

I am having trouble rooting Samsung j7 Perx SM-J727P.

I am totally new to rooting, not sure what I've done wrong.
I started trying to root my SM-J727P by installing TWRP with Odin. This works fine, then I added the superSU v2.82 file to the device's microSD card. I went to install tab in TWRP recovery mode->select storage->Micro SD card->superSU.
Then when I try to flash it, a red message appears saying "Could not mount /data and unable to find crypto footer. Failed to mount /data (Invalid Argument). At the bottom it says "Failed to mount /system (Device or Resource Busy). Failed to mount /data (Invalid Argument.)
After this I read that I need to format storage.
I went to wipe->format data->typed yes and the same message appears, "Failed to mount /system (device or resource busy).
I'm extremely new to this so I don't really know what I'm talking about but do I need to disable dm-verity?
Any help would be greatly appreciated.

I now have manually mounted system and no errors showed, after tapping reboot system, the phone entered a bootloop. Not sure if this is supposed to happen or not and if it is, how long does it take?

This happened to me when I was doing my first root with samsung. What I did was completely start over with a new stock ROM and TWRP. Be sure you have all the right things ticked on Odin. What I had to do with my sm-j700p was un-tick auto-restart when done, and when the TWRP was done flashing, I had to remove the battery instead of wait for it to shut down. Then QUICKLY go into recovery mode by pressing the buttons after you turn it back on. Flash ROM. If I remember correctly, I was so good from there, but the timing with samsung when pushing the buttons apparently is EVERYTHING.
And making sure it is the correct TWRP file. I also made the mistake of picking the wrong TWRP file. Same model and carrier...different year of phone. Software version number is where it's at to get the best info.
Good luck!

May be someone can help may be the bootloader is locked, doesn't boot installed Lineage and it's bricked

I have bought an gt-n8010, which has lineage os installed, but doesn't boot (just splash screen).
So i tried odin to flash the stock rom, but it failed any writing process on the device. In Download mode there is some info written:
ODIN MODE
PRODUCT NAME: GT-N8010
CURRENT BINARY: Custom
SYSTEM STATUS: Official (What does it mean? Does it mean the Bootloader is locked and the device is bricked?)
RP SWREV: A2
But twrp (2.8.7.0 or so) is/was installed, so i booted into recovery and tried to install other custom roms, but it also failed. "Can't state /data/media".
The File Manager in TWRP shows /data but couldn't enter /data/media.
I remounted /data as RW (at least i thought first, that i did) and the file manager could show me /data/media and i thought i was sucessfull.
But the ROM i had, didn't want to install (it thought this was the wrong hardware) and the /data folder was still mounted Readonly (/cache too).
I loaded another ROM, but that needed a newer TWRP.
So i tried flashing TWRP through TWRP and failed. Tried with Odin and Failed. Tried with the DD command within TWRP and failed.
I realised /cache and /data were still mounted read only (and i assume that this is the same problem in Download Mode when trying to flash with Odin)
So, has anyone any suggestion why i can't get /data and /cache mounted in RW mode and has a solution?
Or are these just symtoms of a locked bootloader.
Finally i got it mounted rw (both Cache and and data) und could copy a file to the /data/media folder, by umount and then mount manually.
Still i either need to upgrade twrp or get a ROM which works with twrp v2.8.7.0, so any suggestions? May be dd with the right /dev/blk.... instead of "dd if=/external_sd/twrp.img of=/dev/block/platform/dw_mmc/by-name/RECOVERY" (fails with writing with I/O Error) may work. But i don´t know which one it is.

I would try to flash a recent TWRP from in the download mode and see if this works.
If there's still the old TWRP after the flash than your eMMC is locked and needs to get replaced.
Is there any other possibility to flash from Download Mode except from Odin3 which i already tried. (Adb doesn´t seem to work detects no devices, fastboot neither).
And why does twrp mount /cache und /data read only on start up?
I also thought that something may be locked, but finally i could mount it RW in twrp by mounting it manually by using umount and mount with tha same options except rw instat of ro.

Sure, you could use heimdall (linux). But Odin 3.09 should work fine for example.
Does it even detect your device?
Yes it detects the device, it connects to the device but it seems it can´t write anything. I´ll post a screenshot later.
