[Q] How to mount EMMC as SDCARD?

I am using aosp roms, so there is no way to save my pictures and videos i take to emmc.
I searched some methods on google.
Now i realized i have to fix vold.fstab file in system/etc
but i have no idea on the codes like this.
Is it possible to mount emmc as sdcard, and mount sdcard as emmc or something else such as sdcard2 or something.
one of them i found was talking about how to bypass apps that require an sd card with no sdcard.
but i wanna use both of them, internal and sdcard together.

IF emmc is supported, you can (maybe?) make it work by running the following in a terminal (on the phone). Worked for me in CM 6.0, never tried in Gingerbread. (# is prompt)
*Unmount SD card via menu 1st*
#cd /sdcard
#ls
*Nothing should show up*
If nothing shows up the SD has been unmounted properly
Remove it now if possible
#cd /mnt/emmc
#ls
IF emmc files show up, continue.
If not, your rom doesn’t support emmc, and there is really not much you can do
#mnt /mnt/emmc /mnt/sdcard

I think they want to use both the SD card and EMMC together, like in a Sense rom, not replace the SD with EMMC.
AFAIK, you can't *save* pictures and things to EMMC on AOSP roms, but I'm pretty sure they can still read any media from it. So you'd just have to put anything you wanted on the internal storage from your computer. I'm pretty sure that's how CM6 was set up, anyway.
I never really use my internal storage, though, so I could be way off.

Depends on the rom. Most AOSP ones now support eMMC scanning, but some still do not. Also, you might not be able to save pictures without using my solution, but you can use any other file manager / save window to navigate to /mnt/emmc and change/save things.

Absolutely. The "easy" way to do it is to modify /system/etc/vold.fstab. Below is the default vold.fstab file from CM7...
Code:
## Vold 2.0 fstab for HTC Incredible
#
## - Koushik Dutta
##
#######################
## Regular device mount
##
## Format: dev_mount <label> <mount_point> <part> <sysfs_path1...>
## label - Label for the volume
## mount_point - Where the volume will be mounted
## part - Partition # (1 based), or 'auto' for first usable partition.
## <sysfs_path> - List of sysfs paths to source devices
######################
# Mounts the first usable partition of the specified device
dev_mount sdcard /mnt/sdcard auto /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1
dev_mount emmc /mnt/emmc 3 /devices/platform/msm_sdcc.3/mmc_host/mmc2
What you want to do is modify the last two lines and swap the sysfs paths, so it looks like the following:
Code:
dev_mount sdcard /mnt/sdcard [b]3 /devices/platform/msm_sdcc.3/mmc_host/mmc2[/b]
dev_mount emmc /mnt/emmc [b]auto /devices/platform/goldfish_mmc.0 /devices/platform/msm_sdcc.2/mmc_host/mmc1[/b]
(Edit: I forgot to include the partition # in the bits of data that need moved. Doh!)
After putting the modified file in place and rebooting, the internal flash (normally known as emmc) will be mounted and labeled as /mnt/sdcard. Everything that uses the sdcard for storage will now be reading and writing to emmc. Likewise, the sdcard will be mounted to /mnt/emmc, so it's still available and readily visible.
The important thing here is to make sure that you have good backups of the content of both storage spaces, and that you remember which is which. It's crucial when you update your ROM, since it will overwrite the vold.fstab file back to default.
Also, before you do this, make sure that you migrate any apps you have stored on SD back to internal storage, or else you'll have to reinstall them afterwards.

I was looking for this. will try now. Thank you!
edit: just tried this, it didn't work. had to replace to original one.

run the following in a terminal or via ADB: mount | grep emmc to figure out what block its named as then run switch to the root account using su then type umount /emmc to unmount the emmc partition. Figure out what sdcards device name is by doing mount | grep sdcard. Unmount it and mount sdcard's device name to /emmc and vice versa.
This wont persist after a reboot but its a good way to try and get it to work without screwing stuff up. Once you get it to work put the values in fstab.

Any suggestions?
Hello all,
Hopefully someone more apt than myself can provide some insight. I am running Synergy 3D version on my DINC. I am trying to either make the eMMc an addition SD card mount point, in order to store apps, etc or partition it to use as vram in some way.
I successfully changed the eMMc into SD card by modding the vold.fstab (per post here), the problem is, DINC will not recognize SD as eMMc.
Any suggestions will be greatly appreciated.
Also, would it even be conceivably possible to partition eMMc as vram?

Darn shame not to be able to use both the emmc and sdcard at the same time. You could do it by converting the sdcard to ext2/3/4 but then when you plug into a non linux box you'll need a ext2/3/4 driver.
Is there a filesystem that is widely readable for both linux and windows?
I guess it might not be a problem if the internal sdcard is ext3 because you could still have the emmc as fat.
Thoughts?
Oh crap... I just tried changing the emmc mount point in fstab to /mnt/sdcard/external_sd and no I've got no boot, presumable because android won't accept a mount point over something that is already mounted (linux can).... I need to find a way to recover...
Would somebody be so kind as to cat /system/etc/vold.fstab here for me? I backed it up... but to the internal sdcard!
Hang on... I can't paste that into vi... vi is bonkers for some reason, not recognising the a key...
I also have nowhere for a non su adb to push the file... or any other files... (permission denied)
and I can't get the CWM recovery mode for some reason....
"Also, would it even be conceivably possible to partition eMMc as vram?"
^ yes it's possible. I'm not that familiar with android yet but I'm sure it's possible

try Remount sd app =) it worked for me well =) dont forget thanks button =D

Do a nandroid just in case, and then flash this thru recovery. http://dinc.does-it.net/Mods/AOSP_Swap_EMMC_and_SD.zip

[HOWTO] mount EMMC and External SD on CM7 as it is on Stock ROMs

Hello Everyone.
In this post, I would like to show how to mount Internal SD card and External SD card when using Cyanogenmod 7 ROM.
I had some issues because CM7 mounts the internal SD card under /mnt/emmc and mounts external SD card under /mnt/sdcard.
As you know, there are many applications that download data using /mnt/sdcard as path and if you have CM7 way of mounting these apps won't work.
So to mount Internal SD card to /mnt/sdcard and External SD card to /mnt/sdcard/external_sd as it is done on Stock ROMs proceed with the following:
1 - Open the file /etc/vold.fstab with your preferred text editor (I use root Explorer) and find and modify the last lines as below an then save:
# internal sdcard
dev_mount emmc /mnt/sdcard 28 /devices/platform/msm_sdcc.1/mmc_host/mmc0/mmc0
# external sdcard
dev_mount sdcard /mnt/sdcard/external_sd auto /devices/platform/msm_sdcc.3/mmc_host/mmc2/mmc2
# otg sdcard
usb_mount sdcard2 /mnt/sdcard/usbStorage auto /devices/platform/msm_hsusb_host.0
#end line
2 - Open the file /system/build.prop with your preferred text editor and find and modify the following lines as it is show an then save:
# notify vold we have internal and external sd
ro.additionalmounts=/mnt/sdcard/external_sd
ro.vold.switchablepair=/mnt/sdcard/external_sd,/mnt/sdcard
3 - Reboot the phone and voilá
This procedure worked for me and I have no issues to mount both my Internal and External SD cards when plugging the phone on my laptop.

a good guide indeed for the CM7 ROM users
I did something similar for all my Gameloft games, EA games, Glu games, and DATA partition, and Download, and all the other stuff, basically i mounted everything off to my 64 GB SD card instead of internal SD
lets give this topic some flight time, stuck for a month, it'll come off by itself
also added to main INDEX

Thanks AllGamer...

thanks, i was looking for something like this for a while.

Thanks so much for this. Thanks a bunch!!!

ICS
Can someone who had flashed ICS Alpha builds tell us if this procedure works on them?
Thanks and I am glad I'd helped someone by doing this post

Testing this out right now on Isotope, let's all keep our fingers crossed.

does it work for other devices cm7 roms??

tried it and didn't work for me. Might have typed it wrong. Will try again.
I only used the file browser to see if i can access both the emmc and the sd card but could only get to the emmc

I will try...

Oh man, thank you!
This worked like a charm on my Epic Touch 4G.

tried this in a aokp rom(hydrogen), and it doesn't work.

Why not mount the emmc to /mnt/sdcard/external_sd in addition to /mnt/eemc for backward compatibility?

Does it work on CM9 too?

I had ICS Passion v13 installed on my Samsung Vibrant before, and my vold.fstab file is a bit different from cm7's. I now have cm7 installed but the vold.fstab file doesn't seem to have changed with the change of roms.
It would be great if you could post the fstab and build.prop files somewhere online from where I can download it and replace in my phone because I don't want to mess up again(I encountered the "encryption failed" bug in ICS today and I tore my hair out fixing that..so yeah.)
Thank you.

Anyone else that's on AOKP have any luck getting this to work??? The flip-flooped SD cards on CM9/AOKP is seriously annoying..

has anyone found a solution for AOKP yet? I find that many of my apps such as google music and my camera don't save files properly. This has caused me to switch back to juggernaut.

If i remember right, this device only accepts 32gb microsd.. think that might be the problem, ace? And on another note, since we are using the phone to try and figure this out, why not insert the card into your computer and fix the format issue like a normal person instead of using all sorts of complicated methods that are way more difficult? it only makes since to use methods already in place to make life easier on us, or unless your a robot, which i can see for developers sometimes they dream in binary :laugh: they tend to use the difficult methods to show off lol.

Pretty sure you have to format any card larger than 32gb from within Android to get the Glide to register it, from what I've read anyway. I've seen several posts referencing this. If formatted on PC, it won't register with our phones.
Since (afaik) there's no way to partition the card from within android, perhaps with an app but no guarantee it will detect a valid card afterwards, you may have to keep it unpartitioned.
I believe there is a post maybe a page back on this particular forum that confirms cards over 32gb will work. Shouldn't have to dig too deep.

So i made 1 partition 64gb uder linux i made fat32 formatted phone have no problem to recognize it. Problem is that when i downloading files larger than 700 mb phone freeze. not sure if that do root or the card ... must do test first with original firmware i think 1.3 ghz kernel is not stable just testing now will give more infos after...

So i was right do not install 1.3 kernel i downgraded to 1.2 ghz and everithing working ok!!! 64gb card confirmed for use in glide

After Swapping memory and then Factory Data Reset memory not Recognised
I changed external memory of 4 GB to internal memory and it worked perfectly . But after factory data reset, [Setting > Backup & Reset > Factory Data Reset] my Qmobile NOIR A6 phone is neither mounting internal memory 2GB, nor external memory (SD card) of 4GB. I have reverted changes made in vold.fstab file but the problem persists. my vold.fstab file exactly as it was befor change. My phone is only showing total space 503 MB when checked through SETTINGS>STORAGE.
I can not use camera or other application that use phone memory or SD card. what is solution please.

I finally found the root of problem. I erroneously renamed the file "vold.fstab" as "vold .fstab" which made it useless for mounting the memory. by correcting the file name problem is solved.

I changed external memory of 4 GB to internal memory and it worked perfectly . But after factory data reset, [Setting > Backup & Reset > Factory Data Reset] my Qmobile NOIR A6 phone is neither mounting internal memory 2GB, nor external memory (SD card) of 4GB. I have reverted changes made in vold.fstab file but the problem persists. my vold.fstab file exactly as it was befor change. My phone is only showing total space 503 MB when checked through SETTINGS>STORAGE.
I can not use camera or other application that use phone memory or SD card. what is solution please.

Don't move the apps to sd, just create a 'link'.
You need init.d support and a properly partitioned sd card. This guide will show you how.

I had the same problem with my S3 Mini, what i did is 1.Install Link2SD. wich created a mount script for the second partition to be mounted to /data/sdext2 at boottime
and then i also got the INSUFFICIENT SPACE error when i tried to move. so i looked for the init.d script at /etc/init.d/ its called link2sd or someting like that and then 2. i manually changed that script to include "mount -o bind" commands so i could link manually my copied data maps on the second partition to the 'local' /sdcard/Android/data or ../obb
it worked but you have to remount the /etc directory to get write acces to be able to change the init scripts and also you are depending on a kernel wich supports init.d scripts.
took me a few days to figure it out but i just got my first android since 2 weeks and only have some linux/unix experience so i get the commands.

How , can you explain please

I got a Samsung S3 Mini from AT&T the other day and I can install apps to sd card with the stock rom! here are my phone specs:
Model number: Sumsung-SM-G730A
Android version:
4.2.2
Baseband version:
G730AUCUAMH4
Kernel Version:
3.4.0-1299773

Hi
I use this program and it works very good https://play.google.com/store/apps/details?id=com.slf.ListglApp
1. Install
2. options/move data
3. Select apps to move
4. start, it will work,
5. each time you wanna play or run any app only select mount (the chain in the right side), if you wanna move more apps select unmount and move data again, and that's all.

Go to: [TOOL] DirectoryBind - move data to external_sd (GameLoft, Shadowgun etc.) ROOT req.

Hey guys,
I think I've tried everything but it doesn't look like this is possible to do.
I tried to do it on an un-rooted I9300 4.1.2 with TouchWiz and had no success.
Now I'm using CM 10.2 and I still I'm trying to find something useful. And again with no success.
