Database Info

E: failed to mount /data (no such file or directory)

So not eaxctly sure how this happened.
...currently on TWRP 2.2.1.4, and was trying to update bootloader and recovery.
Somehow in the process of trying to fix it, everything got wiped (yey)
On TWRP, under mount, I can only select Mount System
Then when I try to do anything, i get this:
E: failed to mount /data (no such file or directory)
also
E: tw_format: failed to locate device "/dev/block/mmcblk0p2"
E: Unable to mount '/data' (tw_mount)
E: Unable to mount '/cache' (tw_mount)
Any suggestions are greatly appreciated

You need to give us more info!
What bootloader and rom were you on?
What bootloader and recovery are you on now?
What and how did you try to flash?

Your TWRP is too old and incompatible with your current bootloader. Can you still get to the bootloader menu? DO NOT "WIPE DATA" FROM THE BOOTLOADER MENU. Then use fastboot from a PC to install a more recent TWRP.

Yessir.
Bootloader, not sure. I forgot what part in time I bricked it (months ago). Is there any way to tell via TWRP?
Recovery: TWRP 2.2.1.4
I believe it was CM 10.1. I was attempting to update the bootloader in order to install the new ROM. this was without updating recovery, which is where I think this problem originates.
Thanks!

Power+Volume right? The device will vibrate once, but screen will remain off. Just power boots into the ASUS screen with unlock message, then TWRP 2.2.1.4. No matter what combination or timeing I try I cant get it into the bootloader. (gone right)
I have tried clicking all the possible buttons in TWRP in my desperate attempts to fix.
Will not mount a system.
Nvflash? nope. Dont have the og backup.
Any ideas on what else to try?
Thanks!

Read this and see if buster's method can get you fastboot access.

Got no error when flashing, but got stuck on a loop when try to reboot the phone

ME301T stuck in TWRP

I have an ASUS me301t. Was using the OmniRom 4.4 Nightlies (omni-4.4.2-20140531-me301t-NIGHTLY). The TWRP is version 2.6.3.1.
I unplugged the tablet normally, as I always do at night and the next day was looped in the ASUS logo.
I couldn't do anything else, he kept giving the message: unable to mount /system and /cache.
Choose the Format Data option (after having done the unmounts data partition) and was even worse. Now when I enter in TWRP appears a request for password???
I can cancel but I don't know what to do next.
If i choose Data Format again, appears the following:
Updating partition details…
E: Unable to mount '/system'
E: Unable to mount '/cache'
E: Unable to mount '/data'
Full SELinux support is present.
E: Unable to mount '/cache'
E: Unable to mount '/cache'
Formatting data using make_ext4fs function.
E: Unable to mount '/data'
E: Unable to recreate /data/media folder.
You may need to reboot recovery to be able to use /data again.
Updating partition details…
E: Unable to mount '/system'
E: Unable to mount '/cache'
E: Unable to mount '/data'
E: Unable to mount internal storage
My device is unlocked and i have fastboot on my PC, the tablet is recognized, but I don't know what to do
I see the menssage: You may need to reboot recovery to be able to use /data again. The problem is how? What files and how?
Thank you any help to be provided because at this point I really don't know what to do.

Hi @aNNjo
I use the TWRP mentioned in your post from this forum:
TWRP 2.7.0.1
without problems. Install via fastboot and you should not have issues.
Only time you will, is if you attempt to install CM11 from here:
http://forum.xda-developers.com/showthread.php?t=2761757
as this post/build has its own TWRP and CWM specifially for that ROM only.
Try it out and post back or PM me, let us know.

Hi @DrBeaker
Thank you for your reply to my post. Is very annoying to have the sensation that nobody whant to know about our request for help, either because they do not know answer, either because they do not have time, or do not mind because they do not know us within the forum users.
Unfortunately I had a very busy weekend at work, and only now I will give some attention to the problem of my tablet. I hope that it have salvation. I will try to use the fastboot with the rom referred to see what happens.
I have to first try to know how this is done, because I'm not have the smallest idea of the procedure to be carried out. A little more research.
Thank you once again.

This way i think:
flasboot flash recovery recovery.img

After fastboot flash recovery recovery.img i get the fowling info:
sending 'recovery' <7048 KB>...
OKAY [10.085s]
writing 'recovery'...
and it is there for 1 hour and 15 minutes, it is normal so many time do do the writing?

no that is not normal. should reboot within like 10 - 15 seconds back to rom.
try booting to recovery (hold power and vol - down at same time) and see if recovery boots. If not try an odin flashable recovery for TWRP and flash via latest version of odin.

Device is unlocked, i can see the tablet using fastboot devices.
Recovery boots, but is in old TWRP 2.6.3.1. whit the same errors, asking for a pass and unable to mount partitions

failed to mount /system (invalid argument), Patching system image unconditionally

Hello,
first of all i want to apologize for my bad understanding, i am kind of a noob.
A few months ago i had an stock android 5.1 retail on my moto g XT1032, and i had problems using gapps because i couldnt made a connection to the google servers.
So yesterday i decided to flash a some new custom ROMs , i tried Resurrection Remix, CM12.1, PAC-ROM and Paranoid Android .
Then i got an "Patching system image unconditionally" error and i was stuck on it, so I tried to flash the newest TWRP recovery via fastboot . That worked out fine, but i still got that error Message, so I tried to flash my old Android 5.1 EU Retail. I were able to flash it but i got a bootloop.
Later i found out that when i factory reset my phone, i get an "failed to mount /system (invalid argument)" error.
After hours of chaos i just did random things in my recovery and wiped my internal storage, so I couldnt find my storage folder anymore.
To sum up: I cant flash any rom(stuck at patching system unconditionally...) except the android 5.1 retail but i get an bootloop and i get that "failed to mount /system (invalid argument)" error everytime.
Some Help would be nice.
PS: Sorry for my bad English, I know i messed up hard with my phone.

A same problem with my note 5 SM-N920S I TRIED TO Install custom rom stuck with same two error

honor 8 cant install any firmware and doesn't boot

hello iv been trying to flash emui 5.0 firmware but i always get the same error when i flash the system.img it says FAILED (remote: sparse flash write failure)
and when i tried to flash the cust.img i get FAILED (remote: partition error). so like you figured i damaged the partition
i tried to wipe cache, format data but still doesn't work to flash the system.img and the cust.img but the boot and recovery images are fine to flash.
i also tried the dload method with no luck. so it started of when i updated to nougat 7.0 emui 5.0 from emui 4.1 marsmallow 6.0.1 it didn't update properly and i got some other version
with only google voice input, and crashed. so i decided to flash it manually instead in fastboot but before i flashed i went in to twrp and wiped everything and formated the data.
then i flashed the boot,recovery,cust,system images from the update.app to emui 5.0 for my device but then i damage my partition and got stuck on a boot loop. after that i went
in twrp and wiped everything again flashed the images again but then system and cust img failed errors above. would appreciate any assistance thank you.

are you able to flash any custom ROM?
Try booting to TWRP from TWRP and see if it makes any different instead directly wiping and booting.

You need to flash the TWRP 3.1 for EMUI 5.0. Once you flash the correct file you can boot.
Do one thing, remove USB and just press power key, it will boot to system.

Sorry my bad english.
If you connect the phone to PC, you can browse the internal or external storage?
If you do, or you have an sdcard, use it to dload mode to flash firmware. Use rollback package to revert back to an old firmware. And don't use twrp to flashing firmwares. Its wont work perfectly with nougat firmwares. Dont use it.
From twrp did not work for me. This method send my phone to bootloop and later just booting to erecovery, or stay a permanent bootloop. TWRP gone and just the dload method works 100 percentage.
