[Q] Sdcard became a file - Nexus 5 Q&A, Help & Troubleshooting

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.

TWRP Format data ''failed''

Simple as that. When i try to format data im TWRP it says ''failed''. It's the latest version. Also, isto the wipe data option same as factory reset?
I believe that Wipe Data wipes the /data/ partition with the exeption of the /data/media/ partition.
/data/media/ is basically the internal storage (/sdcard/) directory.
Not sure why it failed. What ROM did you previously have installed?
What method did you use to install TWRP?

I was transfering from stock rooted to aokp i think it was, but iz doesn't work on any other ROM.. i installed it using your guide from transformerforums. So it could be said that they are similar?

Hmm, not sure why it is giving you that error.
IMO, you should not need to format the DATA partition very often. I would try flashing your new ROM after wiping Cache, Davlik, System and Factory Reset.

[Q] Unable to mount storage

My phone crashed and when it came back up, I got that I was unable to mount
cache
system
and
storage in TWRP
I fixed cache and system, but I cannot mount storage. TWRP asks for a password (which was never set).
Is there any way I can do anything to get this fixed without losing everything on my phone (if it isn't lost already)?
Try and fastboot flash the stock cache.img from Google factory image.

I did. That's how I fixed cache.
It's data that's not mounting.
I'll be happy if I can just somehow pull any of my nandroid backups and then I'll completely wipe and format everything.

I think you want to access storage from the pc while on twrp. Not possible. You need to do adb pull commands

F2FS on stock

i wanted to know if it is possible to format our system partition as f2fs and have it work our data partition on kitkat is already f2fs so are we able to do it to system? in twrp i attempted this by fro matting to f2fs but when restoring system it reformats system as ext 4 is there away around this? on twrps website there is a command to keep a the file system it is "tw_rm_rf – uses rm –rf instead of formatting system and data partitions, this option is used to prevent changes to the file system settings such as file system type, " i found it here http://www.teamw.in/twrp2-reference-guide would this help to do this? i don't know where to put this command in though
Edit: on a sidenote i formatted cache as f2fs and it booted
Edit 2: i looked at it again and cache was reformatted back to ext4

Did you ever succeed in getting stock "DATA" partition to F2FS? I couldn't restore my backup and phone wouldn't boot anymore.. so went back to EXT4..
Maybe @djvita knows something, I think he has been experimenting a bit with F2FS..

yes i was able to get only the data partition to f2fs no other partition will stay another format once it boots it reformats or when restoring system in twrp it will restore the system partition as ext 4

interesting.. how did you do it? I did it in TWRP 2.8.1.0 via advanced wipe and after that got stuck on the motorola bootlogo..
That is the same thing I did but after whipeing I restored my data partition. I think the reason you got stuck in a bootloop is because you did not clear dalvic and cache or you do not have the kit Kat boot loader

I tried it again.. this time it worked.. I rebooted after format directly back into recovery and was then able to restore my data from ext4 to f2fs.. not sure, why it didn't work the first time around, but thanks for checking back!

Problem with partition sdcard after fail flash

Hello,
That last night I wanted to flash a new ROM from 4.4 to 5.0.1.
I had some bugs, like my full SD card, therefore i installed nothing like apps or pictures .
So I try to re-flash the ROM again after a factory reset.
But, i can not reflash since it has wipe my SD card ..
So I managed to reconnect my phone and flash a recovery.
However, when I install a ROM (official google, or custom), it no longer detects my SD card
when the flash rom: E: unknown volume for path / sd-ext.
I try everything, I do not know how to repartition as originally my SD card.
I hope she is not dead as impossible to get out of my phone ...
I manage to mount the SD card, but still the sd-ext partition that does not exist ...
I just followed here: http://forum.xda-developers.com/goo...o-repairing-corrupted-data-partition-t2577447
everything works, but again, the sd-ext partition ..
I manage to get to the bootloader, recovery, I can flash a ROM anyway!
However, when I want to take a picture / install / sms .... I get an error "No SD card" or not avaialble space.
I need your help, since yesterday I have no phone ..
Best Regards,

Easiest way to solve is just to flash a factory image - follow ALL the instructions on this page: https://developers.google.com/android/nexus/images
Have a read of RootSU's post about file system issues after updating - explains how and why this happens, and how to fix. I would just do the above though, just so you know you're totally back to stock.
http://forum.xda-developers.com/google-nexus-5/general/sdcard-problems-upgrading-android-t2938749
it looks run, I can now see my sd card, install applications ...
However, some problem:
- In aborescence I have : sdcard, then 0 / legacy / OBB
Is it the same for you? Is like this for 5.0?
- When flash: E unknown volume to path sd-ext. Unable to unmount or mount /system, but I was able to boot; and it seems to work ..
- Clean master does not detect anything (unnecessary file or anything ..) Why?
- What recovery do you recommend?
- In storage: Various weighs 5.68gb, but there is nothing on it, how to clean?

- go to general > stick roll-up and find my data loss/recovery thread it explains all the /sdcard quirks
- you don't have sd-ext, that's why. you can't mount /system if its already mounted
- who knows?
- TWRP
- again check my recovery /loss thread and also my "sdcard problems" thread in general. particularly the part about lost Nandroid backups
Your best bet is to read those threads, find any lost backups and wipe storage via TWRP
"you don't have sd-ext, that's why. you can't mount /system if its already mounted"
It is normal ? Or it's a problem ? How can i fix it ?
I don't have any Nandroid backup, mine didn't worked ..

I'm french, and so i didn't understand all , i'm in which case ?
If i understand well, i just have to wipe "data" partition ?
As you say, i have sdcard\0\0\0
Which one i have to moove ?

Go to /data/media/0. That's where everything should be. When you're in /data/media/0, you shouldn't see any more "0" folders. If you do, take everything out of those "0" folders and put it all in /data/media/0
So for example you should have your photos in /data/media/0/DCIM. If you have /data/media/0/0/0/0/DCIM, obviously that is wrong.
Sometimes its easiest to wipe everything a d start fresh so copy any data you want to keep to PC, then flash the 5.0.1 full factory image, wiping your device back to default completely.
I just did this, i flashed a full factory image this morning, it was the same ..
I made a factory, wipe a new ROm, always the same, i made everything, nothing work .
the sdcard is boring me ..
I don't know what to do ..

It can't be the same if you flash the full factory image. Please explain the exact steps you took to flash full factory image.

fastboot flash system system.img

You didn't do the commands I said. The erase was important
You would need to fastboot flash a custom recovery and either flash a custom ROM from that recovery or flash SuperSU from recovery depending if you want a new ROM or just root
i didn't do the command, but as you can see in the screen, just after "fastboot flash system C:/image-hammerhead-krt16m/system.img"
there is : "erasing system.. OKAY"
So i think it's good no ?

No SD Card
Sorry if wrong thread but, my problem is:
If I'm in twrp it sees the sdcard and all things on it.
In system it doesn't see the things on the SD card.
Please don't return that I have to do a factory reflash.
If I try to download sth. It gives a toast "No Sd Card" .
I can't take it out because I've got a Nexus 4.
Pls. Help me.

[Q] Save files before flashing

In windows, I'd use a partition; in android, are there any folders (like /boot?) that are not deleted after I flash factory images (wiping data obviously)?
I'd like to know this because I have a lot of music, and don't want to have to re-copy it to my phone every time I flash it. (unfortunately N5 does not support sd cards)
My intention was to copy the music to /smth, will it get wiped?

There are only 1 partition which has a filesystem and does not get wiped after the factory reset. But it is only a 16 mb partition with a free space of 10 mb. It is mounted as /persist

There is, but complicated. Because of its location on the emmc you have to edit 6-8 partitions or more. And if there is something which uses the emmc in raw mode and not by the partitions then you could have problems. You will also lose the ability to flash stock rom.
The whole thing is unecessary if you are using twrp recovery and not cwm, because twrp will not fotmat the /data partition. It will just remove every folder and file except the /data/media/0 folder which contains all the files you have on the internal storage.

Flashing without wipe will keep my applications and everything, so it's usually just useless ( not worth ); and flashing with wipe will delete any folders. Are you saying there's no way :/

Listen. If you use TWRP and do WIPE in TWRP it will not delete /data/media/0 folder. So with twrp you can flash roms with wipes without worrying to lose your music and pictures.
If you flash stock rom with fastoot you lose everything.
If you flash rom with wipe in cwm you lose everything.

Nice! This is very useful, I didn't know it was possible to flash factory images through a recovery; so I'll just have to move my music there and it'll stay forever. Just asking now, what will happen to the recovery (which should be stored in /recovery?) if I flash with fastboot, will it get wiped aswell? Thank you so much for your answers

That /data/media/0 folder is the folder of the internal storage. So your music is already there. To flash stock rom in twrp recovery you will need a flashable zip version of the stock rom. These does not contains recovery image so twrp will persist.
You cant flash stock rom from google's site in twrp.

Its complicated. That recovery folder if it exists, on stock roms there arent any folder called recovery, is a temporary folder. It is extracted from the kernel's ramdisk. As the its name says it is a ramdisk so if you turn off your phone it is gone and all its content.
Get a stock rom in a flashable zip. Do a wipe in twrp and flash the stock rom.
