partitions seem to be locked, cant format

i had a recent soft brick in which for some reason, i couldnt decrypt, with this, i couldnt load anything on android besides twrp and fastboot.. when i try reformatting and wiping data, it seems to fail.. for example, i go to format with twrp and it hangs, if i try installing anything itll fail to load any data onto that partition.. if i could reformat that partition back to its useful state, without the encryption issue i could reinstall a rom and fix this issue
any ideas?
when i attempt to do anything in twrp.. i get this error
Updating partition details
E: error opening ' /data/media '
E: error: No such file or directory
just a test, i tried to create a new folder in /data, and it says its a read-only filesystem

Your partition is probably encrypted. The only way to access to your data is to decrypt it before you can do anything. Do you have a password for it?

"Format data" should do this. In which way doesn't it work for you?

when i attempt to format data, format fails, it will not let me touch the /data partition, when it does mount, it mounts as read-only.. the partition itself, possibly partition table or something is damaged because it cannot be formatted and nothing can be written to it
it would seem like the internal storage is screwed.. but the other partitions seem to work fine, even able to use command-line from twrp to check fstab and try to mount manually... im not sure how to completely delete and recreate a partition in fdisk, if possible on here

No error message? No log file? Just "fails"?
You could try running "/sbin/make_ext4fs /dev/block/mmcblk0p8" manually from adb shell.

You can't use fdisk on the internal storage - it uses a combination of GPT and a proprietary partition table.

the errors i receive are above..trying different things ive received the error that the partition is write one... are there any tools for redoing the entire internal storage?

maybe this could work.. since the other partitions seem to work just fine, as they were not encrypted, what if i edited fstab to mount partitions on a MicroSD card pre-partitioned to act as /data and /cache, then install a rom... unless there are ROMs designed to utilize an external SD for installation?... either way if i can work around these two partitions i could get into a working android system where i can find more tools to assist in removing and recreating those broken partitions
ive considered trying to use fastboot to replace the twrp recovery with a stock asus recovery partition and try to fix the issue from that, but i doubt that would be of any use

Instead you should try it cause i'm pretty sure it will fix your partition.Just install the stock recovery and do a Wipe Data first. If all goes well you can go ahead and flash a stock rom from MicroSD or install the TWRP again and check if it's working.

are you saying write over twrp with the stock recovery partition with fastboot, then boot into the recovery partition from the power + volume down menu and see if that recovery image will reset to factory defaults?... if so, where would i even get that recovery image?.. and if you mean just try installing a stock rom through TWRP, ive already been there, done that, and it hangs on formatting

If you follow the link i posted previously you will find the stock recovery (from the latest asus firmware) as an attachment to that post.
After you flash it via Fastboot, do a Wipe Data from the bootloader menu (the one with the 3 icons) after that just follow "restore with stock recovery" procedure from my All in One Thread (it's a sticky post under General Forum).
That should fix your issue and get you to a new clean starting point.

well, ill try that as soon as i wake up.. if it doesnt work though i am prepared to install something thatll run those partitions of an external microsd though.. wonder why no roms exist specifically for that?... seems like an ultra-secure rom for the ultra-paranoid to be able to pop out their microsd and hide it with all user data stored on it

Data2SD already exists.
Did you already try to format your data partition from adb shell?

data2sd seems to be something thats applied after a rom is successfully installed, not sure that would help me
anyway, i tried the stock recovery image and it just hangs on an android graphic with a rotating blue wireframe inside its chest and a blue progress bar, but it doesnt actually do anything else
edit: wait a minute.. i see how this goes with the data2sd... i download a data2sd kernal, since i install cleanrom i can add this to the installations list of kernals, the data2sd kernal will mount external SD cards as the /data, cache, and sdcard partitions, allowing me to bypass the issue im having completely and use a 64gb microsd card as my primary storage... very interesting indeed

aah, fantastic, cant even get into fastboot mode to put twrp back on for the data2sd method.. so it would seem now my tablet is COMPLETELY toast

I see, that's forced boot to recovery because of "wipe data" selected from the bootloader menu.
I don't know how long wiping data takes, maybe you are just not patient enough to let it finish?

no, it finished, then said it was booting the recovery image afterwards, then i let it sit for about 2 hours when i went to do something else and it hanged on that screen... no way to fix this from apx mode?

APX mode is only useful if you have nvflash, the wheelie tool, and the blob file for your device, which you'd have needed to create with firmware 9.4.5.26 or earlier and the hacked bootloader from androidroot.mobi.

Is not having external SDCard an issue for rooting?

I'll try to explain myself before people jump at me. I saw another thread with same question but seems like people misunderstood the question.
I am not talking about "lack" of memory, or not having another 32/64gb availble, etc.
I'll give you an example to what I am referring to:
Recently I decided that my rooted S2 needs a little 'refreshing', meaning - not just a wipe, but a complete format, to start from scratch. So I formatted everything, including /system and /emmc partitions. I then re-booted to recovery and had my rom file on the SD card so i was able to get a clean install.
Now, the question is - say I am at a stage when I need to 'refresh' the phone and wipe everything out. How do I then access the rom file for new install if I don't have external SD Card?
Thanks.

with adb.

What I do when I want a clean start, is I will load the rom/gapps/kernel to my phone, go to recovery, factory reset (with system if you choose), then flash all the things you want, then go back and wipe internal storage after. Then you're left with a fresh version of the ROM you want to install and no files whatsoever in the memory. Hope that helps.

I had the same suspicions a while ago. Basically with the nexus 5, even without an external sd, you can still do a full wipe of everything other than your storage. There is a path on the internal storage which essentially acts like an sd card, and when doing wipes in recovery it will not be wiped, unless of course you specifically choose to format /sdcard or all of /data. Read here for more info. I found that explanation very helpful.
So to answer your question, no, its not an issue.

I have the same issue, with my OCD, that I always need a complete wipe of EVERYTHING.
One option, I recommend if that's not an option at the time of flash, is to simply "reset" in settings. It clears out the whole SD, which is something I usually want to do when I want a FULL flash

Reset in settings just uses recovery unless something changed I haven't realised?
It should be down to what recovery you have (stock vs custom) as to whether a reset (regardless of how you initiate it) wipes /sdcard or not... or are you saying that's changed now?

Problem with factory reset, as far as I know, is that it does not wipe out everything. When I do factory reset in my S2, I still see old folders (even though empty) from before the wipe. That's why I like to format everything clean. When I mean clean, I don't want to see any old folder in there

OK, but if you do that, where do you 'keep' the rom file and how do you flash it?

Android Debug Bridge. It allows you to communicate with your phone via command line tools.
You would keep the rom somewhere on your internal storage (data/media) just like you would on any other phone. Then after wiping, you would simply choose to install zip from sdcard and your rom, along with any other flashable zip on your sdcard will be available to install. Basically when you do a typical full wipe from a custom recovery, the contents of your internal storage/sdcard are not wiped.

Lately, I've noticed that it wipes the Data as well. Unless It was only on CWM that it happened? I had installed CM11 with CWM and wanted to reset my SD. I used the reset feature and it erased everything, except the OS

I would flash the Rom first, then do the factory reset, the only downside is the nandroid you made may be lost, unless you uploaded it to GDrive or something.

3. Rooting
Now that your phone has an unlocked bootloader and a custom recovery installed you have a two options to gain root (Pick one or the other. You don't need to do both)
Option A) Flash SuperSU binaries which will give you root with the stock rom
Confirm that you have downloaded the SuperSU zip from the downloads section above and that it is located in the platform-tools folder inside of the android-sdk-windows folder on your desktop.
Turn the phone off then boot into the bootloader. (volume down + power). Once in the bootloader use the volume rockers to scroll onto Recovery Mode, then press power to select it. This should bring you into your newly installed custom recovery. Leave the phone at the home page of the custom recovery.
Open a command prompt window and run the following commands:
Code:
cd Desktop/android-sdk-windows/platform-tools
Code:
adb push UPDATE-SuperSU-v[COLOR="Red"]X[/COLOR].[COLOR="red"]XX[/COLOR].zip /sdcard/
This will copy the SuperSU zip onto your phone. Once the command has completed continue.
Instructions for TeamWin Recovery Project (TWRP):
Install > browse to SuperSU zip and select the it
Swipe to confirm the installation. Then reboot.
Click to expand...
Click to collapse
It shows how to "Push" a file to your phone. That is the best way, IMO. But instead of SuperSU, just "adb push ROM.zip /sdcard/"

sbi1 said:

Flashing the rom? Its honestly not any more complicated than flashing a rom for any other device. You download the rom to your internal storage. Boot into recovery. Then do a full wipe:
TWRP Full Wipe:
- Wipe
- Advanced wipe
- Select all, except internal storage
- Swipe to wipe
CWM Full Wipe:
- wipe data/factory reset
- wipe cache partition
- advanced > wipe dalvik cache
- mounts and storage > format /system
Finally you can then flash the rom (and gapps).

sbi1 said:

It's not really and if you're rooting and flashing any device, adb is essential knowledge.
Once you've installed adb (millions of guides on the net) you just boot into recovery then connect to pc via usb.
adb commands are run from cmd prompt.
For example...
adb push c:\users\sbi1\desktop\rom.zip /sdcard
Would push the file on your windows desktop called rom.zip to your sdcard.
You can even sideload from recovery.
Or better yet,.just don't wipe /sdcard. It has no benefit other than looking tidy anyway

[Q] Sdcard became a file

my sdcard in root explorer became read only and a file and is now legacy. this first started when i tried to boot into TWRP 2.8 and did not boot so i tried to fastboot erase cache and that is when i had problems. I also don't have an IMEI number but i have a backup. TWRP can read the sdcard though

Try fastboot flashing the cache.img.

Fixed becasue i had a back up and just restored the cache and efs from another ROM

is the sdcard mounted in cache or something?

No but you mentioned that you erased the cache in fastboot. Normally, the cache should reformat. If it doesn't, you lose your cache file system. The phone is still useable but may exhibit odd behavior.

[Q] FORMAT Data/Media... ?

I would like to format my /dat/media.. and then I would like to re-flash the ROM I am using. Since we all know the Note 5 does not have a sdCard port/reader
I can not figure out were to put my ROM that I will be flashing. There is no safe place to store it is there if I do a full FORMAT of /data/media. If I
format /data/media wont that wipe everything ?? even my image file of my ROM. Normally I would store it on an external sdCard then format /data/media..
and then copy the ROM image file back from the sdCard to the phones internal sdcard.
Bottom line .... I want to WIPE my entire phone EVEN /data/media then re-flash my ROM.
Thank you for any tips help.
My phone currently is Rooted and running [MULTI-LANG-6.0.1] TEKXodus HYBRID N5/S7Edge URv7.5E 5/04/16 N920X/G928X

If you have twrp recovery, it will not touch your internal sdcard or any of it's contents unless
you purposely click on the advanced wipe option indicating that you actually want to format it.
By default the internal sdcard in twrp is not check marked.
Simply doing a "Wipe" and a "Factory Reset" in twrp will not format, wipe or delete anything
located in your internal sdcard.
Good luck,
Have a great day!

If I do it your way it will still leave all the stuff in the internal area and without doing a format DATA ( YES ) the stuff in /data/media will also still be untouched.. I want all traces of old user installed programs gone.

Wipe: cache devcache data internal system and then FORMAT DATA ( data/media )

To me this seems like it will wipe the ENTIRE PHONE ... were would a safe place to put the ROM be so I can flash it after ..??

Copy the image file into your computer then after the wipe copy it back into the phone while the phone is still in the twrp screen.

0 mb in TWRP internal storage

I searched for an answer and noticed it's a common issue. I am trying to flash a kernel on to my already flashed rom. I was wondering if there is a more current fix. More importantly, how can this be avoided in the future. Thank you guys!

Its caused by a bug/error with either the filesystem or encryption.
Did you wipe data after flashing the new ROM? Data from stock usually doesn't work with custom ROMs.
Do you have a PIN/password on Android?
Are you using the latest build of TWRP?
Press the menu button at the bottom of the screen in TWRP and post what the error message is in the red text.

It's caused by no root access

Something is probably wrong with the data partition. TWRP should always have root access.
Try in TWRP:
Wipe > Format Data > Slide to format
This will erase the data partition, so backup everything to a PC in Android first if needed. It should allow TWRP to mount /data again.

I've debated on doing this. I'm not worried about losing pictures texts etc as they're backed up.
I read that it essentially leaves the device with no OS. If that's wrong please let me know!

I have found that if I choose Slot A and reboot system it reboots me in to TWRP. If I choose Slot B it runs the OS like normal (except I still have issues using Facebook and it's services).
The ROM works and I can perform all the custom mods on it. I just want to flash a kernel and the problem persists. 0 mb in storage.
It's trial and error at this point. Fail fast fail forward. I have another phone I can use but I love the OnePlus. Any help will be appreciated!

I'm not willing to risk it until I know how to get the custom ROM on to the storage to flash it.

Yes formating by typing in yes will wipe it all,everything including pictures, with no rom on it at all. If u choose to do that, don't close twrp. Instead you should be able mount after wards, once mounted transfer the magisk zip, twrp, and your custom rom(has to be 1.5gb not 200mb through magisk). Flash magesik, install ram disk twrp, install rom. That was a method I've done before but if u want to keep everything there is other way
fastboot boot twrp.img, that command boots twrp if u have it or don't, installing to ram disk makes it permant...this boot command is just a one time thing each time. It's what I do when new firmware update, I loose root but I regain it each time

Never heard of formating data removing the OS, that would be if you wipe the system and normal wipe is like a factory data reset and therefore will not wipe your phone of the OS

Try this in recovery, sometimes its known to work.
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to EXT2.
Repeat the same process selecting Ext4
Wipe > Advanced Wipe > Check Data and press Repair or Change File System > Change File System > Change it to back to EXT4.
Try formatting data after this.

Since you dont care about the data on the phone I would just do 1 of 2 things. 1st I would reflash twrp on to you phone if that doesn't work then I would just grab the fastboot ROM and just flash your phone back to full stock reroot and install twrp from scratch. I would not try to start repairing partitions. I wouldn't want to worry about screwing up the EFS partition

Well in an update, I formatted the
Storage and now I'm stuck in bootloader screen. It's unlocked but I'm having a hard time flashing a ROM through adb.

I use the twrp version 3.3.1-2
Best would be to just use fast command to boot it
But it should be under wipe/format data/then type in yes

That was what I was trying to have you avoid. If your can boot to fastboot download the fastboot ROM I told you to and run the flash-all.bat file. If your on 9.5.8 make sure you use the fastboot ROM of the same version. Do not flash azip of a different version firmware like 9.5.7.

It happens to me any time I'm in twrp and flash a rom then reflash twrp. It doesn't matter if I flash Magisk or not the issue always happens. What I do is use a USB C flash drive and plug it in when I want to flash/backup a rom. This way I can always access it. After flashing any rom then booting I'm always able to access my internal storage again. It seems like a bug in twrp.
The strange part is when this bug happens your files are encrypted in a 0 folder but you can still copy from your PC to your internal storage while in twrp.

I essentially soft bricked my device. Called OnePlus and they got me up and running. That's awesome that they have that service!

Are you removing all security? Pattern, pin and fingerprints? Are you decrypted? Never had an issue with flashing a ROM causing these issues which is why I'm asking. Something you've done at some point is causing this

I'm not sure what that was. Ironically enough I am now stuck in TWRP boot loop. Hopefully I can figure this out otherwise I have to call oneplus again.
I will admit I may not know everything but it's trial and error. I don't have anyone to really teach me this so I try to read the forums and learn. You guys have been great!
