[Q] Mounting question. 'No such device or address' - Android Q&A, Help & Troubleshooting

Hello.
I have a Motorola Razr M device, but I guess this (these) question is more global.
Initially it has the following directory structure:
\system - internal ~1,5 gb memory
\data - internal ~5 gb memory
\sdcard - link to \mnt\sdcard
\mnt\sdcard - the fuse mirror of \data\media
\mnt\external1 - external sdcard.
After some manipulations, I've managed to simplify this situation:
1) I've disabled fuse of sdcard.
2) In vold.fstab I've replaced
Code:
sdcard /mnt/external1::lun ~auto /devices/platform/msm_sdcc.3/mmc_host
to
Code:
sdcard /mnt/sdcard::lun ~auto /devices/platform/msm_sdcc.3/mmc_host
After this I've encountered few problems:
- Settings|Storage menu cause Settings to crash;
- Neither Camera mode nor MTP mode worked when connecting to PC (Mass Storage Mode didn't work also)
After some googling I've found strange hack: I've added
Code:
external /mnt/external1 ~auto /data/media
Nothing changed in [mount] output, but everything except [Mass Storage Mode] works.
{This is the first question: is this possible to make MSM work?}
Now when I pull sd card out of my phone, it shows message 'Internal memory unexpectedly removed'. However, when I put it in again, sometimes it MOUNTS it, sometimes it DOESN'T (until restart).
When it didn't mount sdcard automatically, I've tried to do that manually (WITHOUT RESTART). I failed. I've tried different mount commands, all of which showed me 'No such device or address':
Code:
mount -w -t vfat /devices/platform/msm_sdcc.3/mmc_host /mnt/sdcard
mount -w -t vfat /dev/block/vold/179:97 /mnt/sdcard
mount -w -t vfat /dev/block/vold/179:96 /mnt/sdcard
and so on.
Actually, I've checked that mmc_host file doesn't exist, but /dev/block/vold/179:97 does! So why does vold's dev_mount works, but manual mounting doesn't? How do I make sdcard automount when reinserted? Or at least accomplish this manually.
THANK YOU FOR ANY RESPONSE GIVEN!

So, no experts out there on entire xda?

Stuck in a loop...

I'm running 2.03 and my browser started crashing so I did a reboot. Now I keep looping between the ViewSonic screen and gtablet screen. I've tried several restores through ClockWorkMod and it still doesn't work. I thought I could try to do the upgrade.zip off of a sd card but how do I get the system to recongize it and not the internal memory?
Stupid question : Have you done a user data wipe/system data wipe from CW?
If cw is not seeing the internal sd and the updates located on the internal sd are not working with full users data wipe, then a nvflash push from pc will have to be done to vanilla tnt, then do an update to get clockwork back, then tnt lite 2.0 with clockwork?
You might need to do a re-partition of your SD card (or rather, of the internal SD card memory) from clockwork mod. That has gotten other people out of a boot loop. This most likely has something to do with partitions getting corrupted, which seems to occasionally happen when you are flashing ROMs. You might want to search the forum for SD card partition and boot loop, I know several people have had the same issue.
There is also the APX mode as a backup mechanism if that fails. Search forum for that one too - it's basically a backup to the normal CW or other recovery that lets you flash a fresh ROM even if all else has failed. But I don't think you need to go there if your recovery is still working fine.

Yes, tried nearly everything I can in Clock and nothing changes the loop. I thought in the worst case you could always find a way to get the system back to it's original state but no luck so far.
another option is this

I have never done the partiton of my sdcard... so I guess that might work also.

HELP!!! I think my data partition just go hosed, all I tried to do was restore a backup since I was getting a lot of FC, all trying to access my data folder according to logcat....what do I do, will redoing the partition of my sdcard fix the errors below. How do I repartition and what settings do I use? I was trying to do the restore since I too got stuck in reboot loop. I have the logcat ouput if any dev is interested in seeing it.
Trying to restore backup in clockworkmod I get this:
ClockworkMod Recovery v2.5.1.1-bekit-0.8
Checking MD5 sums...
Erasing boot before restore

rc, thanks for the help. Honestly partitioning is something I've never fully understood so I wasn't even sure how to do that. I went into CW and then advanced settings and chose to partition the sd card. The only problem is I didn't know what settings to use so I just used the first ones to pop up. After doing that I did a reboot and things worked fine.
I was going to go back and try a CW restore and see if I could get everything back but now it can't find the restore file. I assume that happened when I tried to reformat the card.

The restore files were are stored on the internal sdcard, so when you formatted, you wiped them out...is my guess. You could have used adb to save them off before hand and then put them back after format.
For the benefit of others, here is how I fixed this:
-Boot into clockworkmod
-Used adb to copy off all sdcard files (including backup files to use in restore)
-Use CW to partition the sdcard (2048mb ext, 256mb swap)
-Tried to copy backup files back...see issues below
-Restore backup files
-Back to working tab
Two issues I had, one is that for the life of me, I could not get the backup files back onto the sdcard. adb must not like windows because it had issues copying the files back unless you copy them to the root of the device. Even then I tried to shell into the device and move the files to the sdcard, but then CW would not see the files, when I reboot the device and try again, the files were gone. I tried to just copy the update.zip file, again CW didn't see the file, and reboot caused it to disappear as well. I managed to mount the tab in USB mode and copy the files to the sdcard using windows. Afterwards CW didn't see the files either.
I figured the system image was good, rebooted to start from scratch, and the setup program ran. I tried to tap the screen bu nothing would happen. Issue two from the log, is that it the setup wizard ignores touch evens if there is no phone interface...reboot again, back into CW, and this time it saw my backup files, restore, then good to go.
My next step would have been to delete the setupwizard apk, wipe data, boot into android, copy backup files, reboot, restore, but not needed finally.
Have other people run into the above issue where you copy files to the sdcard uin adb while within CW, and the files don't stick. How do you get around this?

Thanks, sad to say I am back in a reboot loop, so I have to do this all over again...uggg
I have shut my tablet off by holding down the power button and bypassing the shutdown screen, wonder if this corrupted the data partition.
I had the reboot problem when trying to load 2.0.0
My fix: Loaded original vanilla via sdcard (took two load tries) then retried 2.0.0 via sdcard and it worked.
please help to make my data read write

Storage Swap under 4.2.2

After 1000 forum pages later I setup a small script under init.d for the storage swap under 4.2.2 which works more or less:
sleep 3
mount -o remount,rw /
mount -t vfat -o umask=0000 /dev/block/vold/179:97 /mnt/shell/emulated
mount -o bind /data/media/0 /storage/sdcard1
chown system /data/media/0
chgrp sdcard_rw /data/media/0
chmod 0075 /data/media/0
mount -o remount, ro /
But now I do not know how to progress further,it looks good under x-plorer and Root explorer (storage swapped), but under the normal menue the primary storage is shown as the internal one. (However, programme files are installed on the ext. SD card correctly) Anyone having a good idea?
For those who are interested in giving it a try (this is at your own risk!), until it is completely fixed and there is a more comprehensive description, it is more for people with some background, at least:
DO A BACKUP FIRST! (e.g. with TWRP, if you end up in a boot loop, you can at least go back to the latest running system)
1) create a script, e.g. with SMmanager ads under /etc/init.d and copy text from above into it and save
2) activate boot, su and executable for the script
3) save file/script
4) reboot, swap (of the mounts) will be done
5) do a manual transfer, of the files and folders from one storage to the other.
That means that you should transfer at least the files under /data/media/0 to mnt/shell/emulated/0 (I used root explorer), same for legacy and obb.
Note that under 4.2.2 the obb folder under android has been moved due to the multiuser capability under the same level as the user folders (0, 10, 11 e.g. if you have three users), so if you have (after the transfer from /data/media/0) files under mnt/shell/emulated/0/android/obb transfer the files to avoid a redownload and waste of storage to mnt/shell/emulated/obb e.g. using roor explorer.
After that you will see the external SDcard folder mnt/shell/emulated/0 as internal storage (using an explorer, works also if you connected to windows via USB, but, again, not in the internal menue)
and /data/media/0 as external storage.
TWRP folder can/should be found under mnt/shell/emulated.
6) Keep a copy of the script on your ext. sdcard, after an update the file will be lost and you can copy it back to init.d (e.g. using root explorer)
7) In case you want to revert to normal mount delete script from init.d and reboot (and copy back files manually)
That is in principle all and again it works, but not flawless (indication under menue, rights of files from internal sd under multiuser), so I would appreciate some constructive comments to improve it. Again, I am at the end of my (limited) knowledge...
As it works, it seems to be primary an indication issue...

Update 13.04
What does the script do?
-mounts your user data to the external SDcard
-ext. SDcard will be used as your internal storage
-internal storage will show up as external storage (sdcard1) can be used, too
What does not work?
-storage swap is not correctly displayed under the system menue, -this seems to be merely an indication issue
What you need before you can start?
-Root
-TWRP (or equivalent)
-Root explorer (or equivalent)
-SMmanager ads (or equivalent
How to do it?
1) DO A BACKUP OF THE SYSTEM FIRST! (e.g. with TWRP, if you end up in a boot loop, you can at least go back to the latest running system)
2) copy folder "emulated" from /mnt/shell to your ext. SDcard, /storage/sdcard1 (use root explorer),- you will delete the redundant data from your internal storage later after the reboot
3) create a script, e.g. with SMmanager ads under /etc/init.d and copy text from above into it and save:
sleep 5
mount -o remount,rw /
mkdir /data/newext_sd
mkdir /data/newext_sd/myfolder
mount -t vfat -o umask=0000 /dev/block/vold/179:97 /mnt/shell
mount -o bind /data/newext_sd /storage/sdcard1
chmod 0075 /data/newext_sd
chown system /data/newext_sd
chgrp sdcard_rw /data/newext_sd
chmod 0777 /data/newext_sd/myfolder
chown root /data/newext_sd/myfolder
chgrp root /data/newext_sd/myfolder
mount -o remount,ro /
4) activate boot, su and executable for the script
5) save script, again
6) reboot, swap (of the mounts) will be done
7) if you get a message that system process do not run properly, press wait and it should not reappear (you may also delete the caches, again, with TWRP)
8) delete redundant data, all folders under /data/media, use root explorer
9) keep a copy of the script on your ext. sdcard, after a rom update the file will be lost and you can copy it back to init.d (e.g. using root explorer) (and reboot)
10) in case you want to revert to normal mount delete script from /etc/init.d and reboot (and copy back files manually)
11) in case you want to reintegrate already existing data from your ext. SDcard to your new user folder structure go with the root launcher to /mnt/shell to access the root of your card and copy any content under your user folder /mnt/shell/emulated/0.
Enjoy...
AS BEFORE, YOU TINKER AT YOUR OWN RISK
Sorry... but storage swapping works in the latest JB's.
Greets Gunnar
No reason to be sorry ,guess where the script came from?
But sharing was the intention.
PS: a few more thanks would have been nice, anyway...
OK, just misunderstood it.
If this is the methodm, which was used in the ROMs of after_silence and zyr3x... it works very well!
Greets Gunnar
Just so I understand:
- please confirm this is already part of the ROM and there is no need to use the scripts...if so, where is the option menu?
- this swaps the internal and external memory so that the internal memory is mapped to the sd card that is removable and the external memory is mapped to the built-in memory which is not removable?
- For the Tmobile Springboard, the built-in memory would be 16GB and for the Mediapad 8GB, I believe. Is that correct?
Advantages and disadvantages, as I see them or understand them.
Advantage:
- I believe this means that the device would see 32GB or 64GB if that was the size of the sd card. Not sure if a 64GB card would work. Why is this an advantage?
Disadvantage:
- That would also mean that you could never remove the sd card. That seems like a disadvantage, but I don't think most people would remove their sd card anyway.
- Sd cards are slower than built-in memory. Is this true?
If anyone wants to add their opinion or comments, please do. If there are any other things to consider, please add them.
Also, don't know how this compares to other methods like Link2SD or those kind of apps.
Thanks all.

Thanks to zyr3x and after_silence the first script is integrated in the last AOPK JB and CM10.1, -so no need for mediapad users with those Roms to pick up the script and we can considered this thread closed 
Nevertheless, I do not want to delete it for the time being, as it may be of use for information also for other 4.2.2 Roms, however with different mounting points and adaptation to be made.
Other methods like Link2SD do not work on 4.2.2, unless there is a new development?
As you say, advantage is that you have additional space for games, nav, etc.
Disadvantage is indeed a performance loss and you need the sd card, -at least for certain apps.
@Maja
Please don't delete this Thread!
Before reading this, I thought this possibility for JB comes from the other developers.
But the thank for this point of development goes to you...
And this could be very helpful for other developers, trying to port JB (4.2.x).
I try to answer directly to the questions...

-> Settings > extended (or such) -> Swap internal und external storages
- this swaps the internal and external memory so that the internal memory is mapped to the sd card that is removable and the external memory is mapped to the built-in memory which is not removable?
-> Thats not this simple... for example: the "sdcard" shows to the card as before, so apps don't use internal memory for storing huge data
- For the Tmobile Springboard, the built-in memory would be 16GB and for the Mediapad 8GB, I believe. Is that correct?
-> don't know the Springboard, but yes, MediaPads internal memory is 8GB, 6GB for data
Advantage:
- I believe this means that the device would see 32GB or 64GB if that was the size of the sd card. Not sure if a 64GB card would work. Why is this an advantage?
-> as described before... not that simple at all - and yes, 64GB Fat32 formatted "MobilUltra" from SanDisk works like a charm!
Disadvantage:
- That would also mean that you could never remove the sd card. That seems like a disadvantage, but I don't think most people would remove their sd card anyway.
-> some apps may not work, the system will boot and work normally. This comes from the fact, that "/data" ist still mapped to the internal memory
(this means, that all App-APKs,-Libs,-Data and the Dalvik-Cache stays in internal memory)
- Sd cards are slower than built-in memory. Is this true?
-> not always, but mostly Just put in a fast card and you'll feel no difference
Also, don't know how this compares to other methods like Link2SD or those kind of apps.
-> forget about such things with JB 4.2.x
Hope this helps.
Greets Gunnar
P.S.: mainly it works like it does with ICS... as far as it could
Sounds good. I'll have to get a 64gb card then. FYI, FAT and FAT32 are still the best bets for interoperability. There are utilties that will format drives in FAT32 even though they are larger than 32GB. The 32GB limit was imposed by Microsoft.
FYI, the Tmobile Springboard is a variant of the Mediapad. It does come with 16GB of memory.
Thanks!
In case you have problems with the
[CM10.1][16.08.2013] CM10.1 for Huawei Mediapad 7" [S7-30Xx] [not for Lite or 10 HD]
version of after_silence, means swap does not work, you can revise the script "02extsd" under /etc/init.d to the following by removing the "if-term" as a temporary fix:
#!/system/bin/sh
sleep 3
mount -o remount,rw /
mount -t vfat -o umask=0000 /dev/block/vold/179:97 /mnt/shell/emulated
mount -o bind /data/media/0 /storage/sdcard1
chown system /data/media/0
chgrp sdcard_rw /data/media/0
chmod 0075 /data/media/0
mount -o remount, ro /
Regardless of the "tick" in the system menue, the swap is performed, anyway. (or you wait for an update...)
I assume there is a problem of the used variable of the "if-term", which should not be too difficult to be changed in the code by zyr3x.

[Q] remount read-write

I have a Huawei T-Mobile Mytouch 4G Q slider (U8730) and i have successfully rooted it. I havent flashed any ROM's or anything like that and i have browsed through alot of the forums and Google and havent found what i need to know. I need to know how to use the "mount a filesytem read-write" command, i know the syntax:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
i just dont know what information to input in the command.
i know i can use:
# mount
and that will give me a lot of info but im not too sure what im looking for.
if theres another thread about this, i apologize, im new to this forum and not 100% how to navigate.

Partition refers to a specific file system. For example the /boot partition contains the kernel and ramdisk for booting up your device (Note: /boot partition and bootloader partition are not the same thing), the /cache partition contains cache files, the /system partitions contains your system apps and other system folder such as bin and xbin and other. What apps are you trying to use that you need to mount rw for? But if you wanted to modify your /system partition for example you would run the following command from ADB shell or terminal emulator to mount it rw (Read/write):
Code:
su
mount -o rw,remount -t ext4 /dev/block/mmcblk0p12 /system

[Q] corrupt /efs folder files ? Unknown Baseband, Unknown IMEI? Some Hope to fix it?

Hello,
I am flashing roms since nearly two years and I got my first big problem 2 days ago.
My GT-i9100 (DBT Germany) was running stable under cm-12.1-20150611-UNOFFICIAL-i9100.zip brought by Lysergic Acid.
When I tried to log on WLAN on Tuesday morning, my rom crashed with a few percent of energy remaining. I charged my battery and started the phone again. I had a message "No Service" and a barred circle. Pin Code was being asked, as well as my lock screen Pin Code.
I thought it was a mobile network operator issue, and that it would be temporary. Didn't care about it, I was able to log in my WLAN network. Then I saw an update (06/17) on xda, that I downloaded and flashed following the installation instructions. I noticed still the "No service" message and the circle barred. I looked at my telephone settings an saw Unknown Baseband, No Signal, Unknown Imei. When I called *#6#, there was a popup with only the Text IMEI no number.
Finally I did sthg really stupid (I didn't google Unknown Baseband Unknown Imei at this time), because I thought wrongly that the issue is a rom, modem or csc issue. Then I decided to flash back to a stable jelly bean version.
Thus, I had to flash the partition with Stock i9100 pit, because I was using a preload modified area partition before.
Then I made my great mistake, that's what I think now, I think I corrupted my /efs folder. I installed a stock firmware from sammobile on my SII (still no service, unknown baseband), then rooted the phone again, and installed
ASNET MIUI v5 (4.8.10) everything is working except this my mobile network unknown baseband, unknown Imei, etc
I tried to look on my external harddrive, if I had any backups from my phone, did not have any /efs backup. :crying:
With root explorer I am able to to see the /efs folder no file is missing I think, but it is certainly corrupt. I am joining a .tar file of this folder here. https mega.nz/#!4IZijDTK!2eZ1lhC01bTEcbzwP7OVe8tePiIm5GNQ_dwpZRZHF0k

I still have the IMEi on the back of my phone.
Is there a way to fix this or is it impossible?

Internal SD Is Now Broken after Going to Lollipop. Need Advice.

I was able to install lollipop on my phone. But I couldn't get root. I lost some information. So I went back to my backup 4.3 within TWRP and that's when it all went to ****. HWuserdata can't be mounted and sometimes internal_sd can't be mounted either.
What I can do:
-Install new roms
-Install backups [restore them]
-Access to adb
-Can push out img through through adb/fastboot
What I can't do:
-with all of the above, the internal sd doesn't mount in ANY of the roms [both 4.3 and 5.1]
-Can't remove /hwuserdata in TWRP
-Can't remove /internal_sd in TWRP [Error message: E: Unable to mount '/internal_sd']
More Error Messages:
E: Block device not present, cannot wipe internal storage.
E: Unknown MTP message type: 1
E: Unable to wipe 'internal_sd'
Updating partition details...
E: Update to mount 'internal_sd'
Available Partitions as in the Wape menu within TWRP 2.8.7.1
-Dalvik Cache
-Cache
-data
-Internal Storage 11975MB
-System
-Custom Storage
-Internal Storage 0MB [There is actually two of these partition.]
-External Storage
-USB OTG
My best guess is delete the internal sd some how. And/or remove /hwuserdata as well. Or completely return it to stock. Then install 4.3, install TWRP 2.8.7.1, install 5.1, and finally install root. I can't find the img file to push out through adb in "Fastboot&Rescue Mode".
Can someone point me to stock img? This didn't fix my issue within TWRP. I tried installing "MT2L03_B148_Stock_ROM.zip" within TWRP.
All advice would greatly be appreciated.
Thanks!
UPDATE 7/2:
sdcard0 / internal_sd is still broken after applying the downgrade and the b309 rom. Does anyone have the stock rom in an img file format?
Download the public preview of B309 from the blog.
Install it as instructed in the blog post. (You will lose your data, so backup.)
To root and get TWRP, do the below.
Credit to Foltz61.
1. Boot to bootloader.
2. Fastboot boot TWRP-L.img
3. Install supersu-2.49.zip (even though I didn't lose root)
4. Reboot back to system.
5. Reboot back to bootloader.
6. fastboot flash recovery TWRP-L.img.
7. fastboot reboot.
8. Boot to recovery and had TWRP
Thanks for the reply. But I am still stuck with a broken sdcard0 / internal_sd partition. Does anyone have a stock rom in an img file format? Applying the B309.zip and downgrading to 4.3 provided by Huawei still hasn't fixed my problem.
Oh my God...... Which version of TWRP did you use when you restored using your 4.3 backup???
Please, tell me you did not use TWRP 2.8.7.1-L or 2.8.7.0-L for that matter???
in current state, maybe you can try use parted to print your current partition table, and paste here
adb within twrp, it has parted builtin, under OS, you need install the binary.
parted /dev/blk/mmcblk0
unit b
print

DO NOT USE TWRP-L IF YOU ARE ON JELLYBEAN 4.3. IT IS MEANT ONLY FOR LOLLIPOP.

I installed 4.3 with the huawei files and went over to 5.1. I am not sure if I am in the clear yet. I have a "emulated 0" partition for my sdcard0/internal_sd. When I open ES file browser, it says "no sdcard can be found". But I can write to this "emulated 0" partition. I am guessing this is still broken? I am on TWRP 2.8.7.0 with 5.1.

Open terminal, type and enter, su, then type and enter, mount. Share with me what mount says.
That's the same as mine

The emulated 0 partition is the same as I have. That should be your internal memory.

Still, to be sure he didn't screw something up since he did use TWRP-L while on 4.3 JellyBean, I still want to see what, mount, displays for him on his terminal.
Emulated partition
I'm using X-plore file manager and I'm not seeing internal_sd but rather getting the internal SD drive showing up under Root/Storage/Emulated/0
I've tried reverting back to 4.3 and associated TWRP, but X-plore still doesn't show internal_sd properly. I'm pretty sure it used to show it properly...or am I imagining it

On 4.3 yes, on 5.1 yes, but on 5.1 it's main location is /data/media/0
You can check by opening terminal and typing then entering, mount.
so as long as it accessible by going to /data/media/0 then its all okay, even though it doesn't show up as an actual drive under X-Plore?
Thanks for your time and help.

Mine is also screwed up after the upgrade and I cannot get back to stock, nor can I get TWRP back. Yes, I've reflashed supersu etc. Here's my dump.

Updated to 5.1 (was a beta tester). After the upgrade, root, but no TWRP. Tried numerous times to reflash TWRP-L but still the stock EMUI 3 persists. Have verified I can fastboot TWRP to restore previous backups and create new backups but cannot make TWRP permanent.
Have tried the reinstall of SuperSI 2.4x and all the steps multiple times with no success. Tried the Huawei downgrade to B148 and that fails as well.
Regarding trying to install TWRP, that is because of the 5.1 Rom. It checks to see if the recovery is stock. If it isn't then it will overwrite the custom recovery. TWRP has to be booted and system has to be mounted as read/write, not read only, in order for it to patch the Rom so TWRP will stick.
I can't help regarding the beta test Rom though. I was not a tester. So I cannot say specifically what changes there were between the beta Rom and official released Rom. Maybe @xordos, @kimtyson, @Iguanadon, @ScoobSTi or someone else can assist regarding your current dilemma.

Try removing anything related to twrp on internal and/or external sd. Backup if needed. Then fastboot boot twrp. You should get the prompt about read/write.
Edit: remember to use 2.8.0 L
Sent from my MT2L03 using XDA Free mobile app
I am also new to the 5.1 fused internal storage. following is what I noticed.
/sdcard is soft link to /storage/emulated/legacy, which in turn is link to /storage/emulated/0, which again is link to /mnt/shell/emulated/0, which is the internal storage fused to /data: /data/media/0.
But some how ES file explorer can not handle it. In ESFileExplorer in my B309, it show /sdcard as a *file* with a tiny link icon, instead of others normal one (like /vendor) which showed as a *folder* with a tiny link. And every time, when I open ESFileExplorer, it also report error, "/sdcard can not find" something like that. I have to go to its settings page, Directory Settings, and set "Home Directory" to "/storage/emulated/0", then the error is gone. For me, I changed it to /storage/sdcard1, which is my external sdcard.
Another side notes, if sometime your app (that requires root) complains can not write to storage, goto SuperSU settings, and disable "Mount namespace separation", this may help resolve lots of problem.
These is more info from the command line, I can not tell the different between /sdcard and /vendor, but ESFileExplorer can not open /sdcard
(when run these "ls" as non-root user, the result is same)
Code:
[email protected]:/ # ls -l sdcard
ls -l sdcard
lrwxrwxrwx root root 1970-01-01 00:20 sdcard -> /storage/emulated/legacy
[email protected]:/ # ls -l vendor
ls -l vendor
lrwxrwxrwx root root 1970-01-01 00:20 vendor -> /system/vendor
[email protected]:/ # ls -l sdcard/
ls -l sdcard/
drwxrwx--- root sdcard_r 2008-12-31 18:48 Alarms
drwxrwx--x root sdcard_r 2015-07-03 03:36 Android
...
[email protected]:/ # ls -l vendor/
ls -l vendor/
drwxr-xr-x root shell 2015-06-24 13:09 etc
drwxr-xr-x root shell 2015-06-24 13:09 firmware
...
PS, Just realized in the phone setting-storage, I can set default storage to "External", then after that /sdcard become normal as it is not link to fused FS anymore:
Code:
[email protected]:/ # ls -l /sdcard
ls -l /sdcard
lrwxrwxrwx root root 1970-01-01 04:15 sdcard -> /storage/sdcard1
[email protected]:/ # ls -l /storage
ls -l /storage
dr-xr-xr-x root root 1970-01-01 04:15 emulated
lrwxrwxrwx root root 1970-01-01 04:15 sdcard0 -> /storage/emulated/0
drwxrwxr-x root sdcard_rw 2015-07-03 12:50 sdcard1
drwx------ root root 1970-01-01 04:15 uicc0
drwx------ root root 1970-01-01 04:15 usbotg
Why did I not have any problems booting into fastboot, flashing TWRP-L through fastboot, booting directly into TWRP, enabling the read/write dialog option, then flashing SuperSu? TWRP survives, root worked, etc
Couldn't have been a more standard way of going about it.
Also, I had a problem with my external SD card being read only after lollipop update, but I think I fixed it by going to settings and changing default storage to external sd card and rebooting. Now both internal and external can be written to.
