[HELP] Modifying mount point of EMMC.

What I need...
Someone to repackage a boot.img for me. Specifically, I need a boot.img unpacked, replace the file "/init.inc.rc" with my version, and repack it. (I'm stuck on all Windows, and cygwin is not an option.)
Purpose/Goal
Fix the annoying fact that /emmc is not accessible to almost all market apps, without resorting to using the modified media scanner from CyanogenMod or anything else drastic.
Do not change fstab. /mnt/emmc and /mnt/sdcard will not change.
NOTE: I am not trying to create a symlink on the FAT32 of the SD card.
My idea
Modify /init.inc.rc to change the EMMC settings. (Changes made, need someone with tools. See above.)
Modify /system/etc/vold.fstab to relocate EMMC mount point.
Directory structure
/sdcard (unchanged)
/sdcard/emmc (new location of emmc)
/emmc (Retarget the symbolic link to new location.)
/mnt/emmc (Change to symlink for compatibility, just in case.)
What I want to know...
This arrangement makes /emmc redundant. Can it be safely removed?
When you connect to a PC, how/what does Android map to USB drives? (I assume it is the mount blocks, not the symlinks.)
What odd behaviors may occur? (e.g. will "Settings->SD & phone storage" freak out?)
Maybe, just maybe: How to bottle this into a flashable .zip? (I'll worry about that later.)
If anyone has any pull with the ROM devs (i.e. Koush, rmk40, et al.), I really want to hear from them.

+1. I'd love to make emmc usable in Winamp

Bzzzt... Sorry.
ARGH!
The internal storage is VFAT also. No symlinks allowed.
Blast you, HTC!

What??
I hate doing this, but editing the original post doesn't bump the thread.
I did not want to create a new thread, but what I need has completely changed.
So. BUMP.

Why HTC, WHY?!
Would there be a way to format emmc to NOT be VFAT?

Progress!!!!
I'm close to getting a boot.img ready to test out on my phone.
I spent yesterday hacking away. I've made a Windows tool for handling boot images. I'm about 80% done with the required features. I have all the unpacking finished. I've repacked the ramdisk. I can generate the SHA hash to sign the image. It's just a matter to gluing the last stages together.

I'm sure it could be done, but this is way more work/hassle that I want to deal with. Major obstacle here is that ALL data on emmc is wiped, and I'm not willing to that.
Assuming there are no hidden "features," my approach should be invisible to the Android layer (i.e. will not break any HTC software). HOWEVER... I'm pretty much Senseless, so I'm not too concerned (for my own use) about HTC's apps.
My biggest concern is that the media scanner will generate duplicates of all files found on emmc. But a/the big motivator for this work is to use Winamp, so I don't really give a whoop.

This was tried by koush when we couldn't get cm6 to scan emmc. It didn't work.

What didn't work? Or how did it not work?

I'm not sure. I wasn't involved in the effort. Koush would be the person to talk to but island how to get a hold of him. I just think the OS rejected mounting a physical drive within a physical drive. But don't let that discourage you. It might be still be possible.

Any progress on this? I really would love to have /emmc accessible as /sdcard.
Why HTC decided to make /data/data so small and put the rest of the space as /emmc is still a mystery to me. This is my only gripe with this phone.

Progress update
I made my first attempt on Friday, which resulted in a boot loop. So, obviously, I'm missing something important. (Battery pull and recover boot fixed the problem.)
I couldn't work on it this weekend. But I'm going to start digging into it some today.
More info:
It didn't get past the slash screen. Since I'm flashing a boot image, this is obviously where the problem is located. I just don't have any error logging to read over. Since I'm cooking on Windows, I'm wondering if my file permissions and ownership are messed up.
Also, while running my update, I observed that the boot image flashing did not seem to take long at all. So, I'm concerned that I didn't even get a complete flash.

That doesn't bode well so far.

just some info
i'm not sure if this will help any of you, but i read before that it said koush tried to get the emmc mounting.. etc... and it didn't work. but - i'm running cm 6.1 stable and winamp can and does read my music found on the internal memory. so it seems to work for me. however - i cannot take picture and have them stored on the internal memory. anyway, good luck.

OK.... I got the ramdisk sorted out. The boot loop is gone. But it doesn't progress past the splash1. sigh.
I need to see the kernel messages, and typically ADB is not available.

CM6 uses a modified media scanner (Android layer) that uses '/mnt' as its base directory, instead of '/mnt/sdcard.' And, as you say, it has its own problems.
I am trying to modify the underlying file system to make hopefully all software work (e.g. HTC stock, Winamp and other media players, 90% of the apps I've played with).

It "works!"
Alright... I have all the tools made, and bugs squashed. So, I can correctly mod a boot image. (Tip: The boot process has a zero warning or error tolerance.)
It fully booted. BUT... A permanent notification "Preparing phone storage.../Checking for errors." did not go away. All emmc directories were absent.
So, I've found a problem. Google didn't return any useful information... Especially annoying is the face that I don't even get a link to the Android source to even get a hint where this notification comes from.
AHA! Fixed that problem. Now, emmc is visible on the sdcard.
NEXT problem (this one I expected):
Media scanner picked up 2 copies of my pictures (I have them on emmc). So, my thought is to start removing links (and references) to emmc in its new location until things clear up.

The double items in media scanner seems like a small issue compared to what it fixes.

More problems created than fixed. (And WHY this is a mess to begin with.)
Postmortem thus far...
Touching ANY code related to where emmc appears will cause Setting to FC if you view the SD & phone storage usage.
Makes media visible to "other" applications, but shows duplicates in HTC's music and gallery apps.
I didn't look too closely at it, but I question that the camera was playing nice with the new config.

SO... I took some time to understand the double items, and why EMMC is such a problem to begin with.
HTC did not modify the media scanner/provider to support EMMC. They modified their APPS. Do a dump of HTC's music and gallery apps. You'll find a LOT of extra code, and a lot of added symbols/strings for handling the phone storage.
In other words, they didn't create a "public" solution. They just made their own private patch, and brushed it under the rug. (How dare we not use THEIR apps???)
Media Scanner/Provider:
I looked at Koush's code changes. I don't understand his changes. I'm not sure how/why it "works." I don't know why it reportedly breaks the HTC apps. I am also not sure that their is a way to mod it to actually fix the issue... Google's code was not written to be extensible. But, I think it may be the way to go in the long run.
What other phones have EMMC? Do they have a fix?

My tools...
There is a lot of code duplication, no GUI, or options. It ain't exactly pretty, but it works.
I'm posting this here for future reference by others wishing to work with boot.img.
Note: This specifically targets 1 file on the ramdisk (init.inc.rc), but with some changes this could do almost anything you would want.
License... Oh. GPL. If you make changes, please send me a patch.
REQUIRES: AutoHotkey (Hey.... it's all I had available, but the code should be easy for anyone to follow and port to another language.)
Runs on Windows (XP). Does not require cygwin. Native GZIP included.

Some applications and files disappear from SD card after SAFELY removal in Windows 7

Good afternoon, dear xda-developers forum members.
I really hope to find some help here.
In last two months I had the following issues:
1. This one happened two times already: after using my phone as a flash in windows 7 and "safely removal" of it, all my applications which were installed on SD card were saying that "Application is no longer installed" when I tried to run it, although other documents and files were readable from ASTRO File Manager, i.e. SD card was mounted. In Settings->Applications all these applications had black icons with SD card image on it and rather with package name than regular application name(for example com.navitel instead of regular Navitel, etc.). I've restored all these applications from Titanium Backup, but I'm afraid that there is something more disappeared also which I don't know about.
2. My "Android" folder on sd card became a file with weird contents(this folder was used for NFS Shift data only). I couldn't restore it. Again: if this folder corrupted, then there is definitely something else also corrupted.
After I saw these things for the first time, I used Windows checkdisk with auto-fix errors. It found a lot of files and put it into "FOUND.000" directory. I recognized in these files few apk-files of installed applications from SD and also few images from my SD. Then I restored applications to SD card and for some time it seemed ok. But one time it happened again.
My assumption is that Android fails to re-mount SD card after I disconnect it from PC.
I don't know what to do... is it Android bug or is it Desire bug or what? I swear that I ALWAYS make "safe USB removal" in Windows before disconnect the USB-cable and I ALWAYS wait for the message "It's now safe to disconnect your device".
I'm very disappointed with all that Please, advise me something useful...
P.S.: If needed I can give you any debug information you want, I'm a programmer, so I've been around

You could try to format your SD card, just backup the contents first, see if that works. As for Android, it does a pretty good job of mounting straight after. What version of Android are you running?

I will, but strange that it happened, because I formatted the flash before using it for the first time...
I have two assumptions:
Maybe I shouldn't press power button to switch the screen off just after disconnecting USB cable from PC. I was doing that as a habit, because every time you disconnect your phone from PC, the screen turns on.
Maybe I shouldn't try to run application which is installed on SD just after disconnecting phone from PC. Maybe I should have waited for a minute. I've tried to do it once, because I wanted to see the result as soon as possible, so the phone said that "Application is no longer installed", I though that Android haven't mount SD yet and tried later. It worked. But next time when I used USB cable, all SD-card apps became uninstalled.

Fast Boot option may be the culprit
In case anyone checks this old thread...
CUT TO THE SOLUTION BELOW -- SEARCH FOR ////
Some (not all) of my apps moved to SD (all by Titanium Backup Pro) have begun to disappear and (sometimes) reappear without warning after I began to add and delete large Virtual Machines created in QEMU from my 16GB SanDisc class 10 microSD card on my HTC Droid Incredible running rooted stock Verizon Android Froyo 2.2.3. I know this thread is far from my phone's "home base", but from what I can tell this problem with disappearing apps located on an sdcard is NOT determined by hardware or even Android version.
I also happen to use LauncherPro by Federico Carnales instead of the built-in HTC Sense launcher. I noted elsewhere on XDA that a user had suggested that because at least some (maybe all) launchers start before the SD Card that this may be a problem, especially if changes are made to the sdcard that the launcher did not perform, or was not active during their performance by other apps such as Titanium Backup. That fits my situation, because I unmounted the SD, physically removed it to a PC, and added/deleted large VM files to save (lots) of time. No problems of this sort before I did this, so there must be some connection.
I noted that other users have tried reformatting SD, substituting different brands of SD, using newer/older SD etc. None of these reliably helped. So I skipped these options.
//// The (simple!) solution I tried that SEEMS to work (only time will tell!) is buried in the main Android Settings (accessed from the Menu button while in Home screen). Under "Applications" there is a setting "Fast Boot" that I checked long ago and forgot about (it seemed like a good thing to do at the time). The text warns "Turn off to use some Market apps" (that shows the age of my 2-yr old used phone and Android OS -- ohmygosh!-- because it refers to Market rather than Google Play Store!) Anyway, I unchecked the option and rebooted the phone.
Yes, it took a bit longer to boot (maybe a whole minute!), but after waiting about another minute ALL my home screen apps had normal icons and loaded properly. Titanium Backup Pro batch scenarios confirmed there were no apps in a forced uninstalled state (i.e. I had not done the deed, the system somehow had done it or at least rendered the apps "invisible" to Titanium, which decided they needed reinstallation).
The only odd behaviour was that auto brightness was turned off after I unchecked Fast Boot and rebooted. Going into Android Settings > Display and rechecking "auto brightness" took care of that. No other oddities or strange behaviours thus far (but it has only been about an hour).
I will report back here on this thread only (Samsung Fascinate > Fascinate Q&A > What just happend? apps on sdcard) if anything else requires reporting. Silence implies success!

[Q] There is insufficient space on this device

I have E4GT with Caulkins 2.9.1.
I have the following storage available on my device:
SD Card 24.25GB
USB Storage 3.25 GB
Device Memory 1.23 GB
I get the following error when trying to update apps, or install new apps:
"There is insufficient space on this device"
I have gone into settings>apps>google play> clear cache. -> no change
I have downloaded App Cache Cleaner app and cleared all cached files. -> no change

The error message is a lie written by a lazy programmer. What's actually happening is that the installation is trying to copy or move a file and can't. To circumvent this problem I have to enter root explorer and look for files related to the program I'm trying to upgrade and delete them. Sometimes I just find dangling files which aren't really needed; other times I have to delete the whole shebang and reinstall the program from scratch. One process that I've noticed can sometimes cause this problem is the auto-Odex routine that is available in the Development folder.
Bottom line though is that this problem has NOTHING to do with your available memory space.

How do I find dangling files in explorer. Is there a was for me to determine which ones are wasted files?
before i read your reply i went into recovery and wiped cached and dalvik cache, thought it worked, because i was finally able to install or update about 3 apps, but then got the same error on the 4th app.
so those steps that have been suggested by others on different devices but with similar errors, did not resolve this issue on E4GT.
thanks for any additional help.

This may help http://bit.ly/GNQOZh take a read. I fought this a while ago and went nuts till I did what I describe.

It's usually, but not always, as simple as looking for files with the name of the program imbedded. The most recent program for me was AudioGalaxy.... so I just searched for and deleted any reference to the program that didn't look essential.
If you're REALLY stumped, then download a program from the Market like Log Viewer, which shows you the real-time system log of your Android operating system. That's how I discovered that a failed file copy was being misinterpreted as a full disc in the first place. It also will show you the name of the file being copied or moved and into which directory. Helpful hint: cut and paste the log into something like Notepad for easier reading.
By all means empty out your caches... but only to remove a potential file that's causing you a problem. Like I said, you haven't run out of free space.
Good luck!

A common source for this error is also that there are partitions on your phone that are not visible in the system settings, but which can fill up too.
If you open a console on your device, i.e. with terminal emulator, and type "df" you should see every partition and how much space is free on it.

You 'cleared data' on the media and still had this issue? http://mikemartinezonline.com/blog/wp-content/uploads/2012/02/03.png I've had this issue a few times with a few people- again it just happed to me yesterday! Seems that the media storage, media hub, oovoodo, and some others were taking up huge amounst of space. In fact my media storage was at 800MB until I cleared it. Especially noticed this for me after adding and removing media and swapping different sd cards.

I cleared the app cache there, and still had the issue. I also went into recovery and cleared cache, dalvik cache.
I didn't try the SDMaid method, so if someone else has this same problem, that may be a place to try.
I ended up starting with scratch with my device, and just upgraded to calkulin 2.9.2.
now my device is functioning as expected, and i can finally install angry birds space...

Well same problem shows up again.
updated to Calkulin 3.0, in hopes to resolve the problem, but still no go.
insufficient space when trying to install or update app from google play.
SD Card: 3.25GB Free / 29.7 GB
USB Storage: 7.29 Free / 11.50 GB
Device: 1.29 GB Free.
It's kind of annoying, is this something that would be resolved by going back to stock. This is getting a bit annoying.
thanks again.

Which app?
Edit: Have you tried clearing data for google play in settings/applications/all yet?

[Q] Storage Space Running Out, Insufficient storage, my phone trying to screw me?

So...
I've had this problem for a while now, getting worse from day to day. I've asked about this before, but it wasnt solved.
Basically my phone is taking up data in the background. Probably updating, downloading something. Its so bad, that if i dont turn off data on the go, my 1.5GB are used in a day. Sync is turned off at all times
And another side effect of that is, that all that data probably has to be stored somewhere. So Im getting the storage space running out error. Kinda annoying cause I cant use gmail, Cant install any apps(insufficient storage available) etc.
I really have no idea where all that data is(after searching through all the folders for a while now)..
I'm on the latest AOKP Milestone(4.2)
Thanks!

There are a couple things I recommend doing in your position. First thing I would do would be to get an app that allows for more informative breakdown of what is using the storage. Something like diskusage should do the trick. This will allow you to see exactly where data is going, opposed to "misc" Perhaps this will show exactly what is taking up the storage, since you are rooted perhaps backups are the problem.
If that doesn't tell you what you want to know, or if you think an app may be using data behind the scenes then the next step I would do is to use some sort of data usage monitor. The built in one may suffice, settings > data usage. If not there may be better apps out there, although to be honest I have zero experience with those.

Uploaded a pic what diskusage says. When i hit media it only opens the file manager and directs me to sd storage
BTW this what Onavo says has been consuming data this month:
Market Downloader - 800MB mobile, 2.4Gb Wifi, all in background - and no, i didnt download anything from the play store on the go and hardly anything on wifi - havent updated my apps in weeks b/c of missing storage
Android OS + Others - 530MB mobile and a whooping 12GB on Wifi! All in Background too.

It looks like you have some nested 0 folders in that pic. Perhaps cleaning that up will clear up some space. Side note, if you haven't updated your custom recovery in a long time it may not be a bad time to look into that.

If I were in your situation, I would probably just get a clean start. This also would get rid of the nesting problem I mentioned above.
- I would make a backup of my current setup, probably just using Titanium Backup.
- Backup everything I want to keep from my phone to my PC, going through the 0 folders.
- Use fastboot to flash factory images, allowing it to wipe everything in the process. The .bat file should do this automatically.
- Use fastboot to install a recent custom recovery.
- Push the sdcard backup from my PC to my phone.
From here you have a couple options, root and reinstall Titanium backup and restore some of your apps (no system data) or go back into custom ROMs. You could flash AOKP again, or pick a different ROM.
A bit heavy handed, but I think that would be the least time consuming option considering the problem(s).

Basically when 4.2 came out, it brought along multi-user functionality. Custom recoveries at the time, when wiping and installing ended up creating the nesting problem. Recoveries then were updated, which doesn't create a bunch of /0 folders (one existing is correct). This was a super common problem about a year ago when 4.2 came to be. There were hundreds of threads about this problem, with more detailed info about what happens, why, and how to fix it. Wiping everything is one of the solutions, and since this isn't your only problem, this would probably be the recommended solution.

I am not sure where you read that a wiping everything isn't possible, but whoever said that is all sorts of wrong. There are multiple ways to wipe things.

Just did what you said and it looks like everything worked! Everything is deleted, I have almost 13 gigs of free space, rooted my phone again and I'll probably install aokp or paranoid in a couple days.
No 0 Folders anymore and I'm sure as hell hoping that my data consumption will be fine now. I'll keep you updated on that in a few weeks again, but thanks for the help!

looks good thanks bud

[Q] Unexplained Consumed Memory

I bought this Samsung Galaxy Tab 3 SM-T210R for my mom its currently running kitkat 4.4.2 non rooted which I am about to fix here soon.
The problem is my mom hardly does anything on this facebook some books recipes and maybe 1 or 2 games and her church stuff and for some ungodly reason it keeps telling her she has low memory around 775mb left and it wont install anything else.
I put a 16gig sd in it for her and moved everything possible over to the SD cleared all the cache from all apps and have gone to the extent of restoring it to factory and it still keeps doing the same thing.
My only thoughts are root it with custom recovery and wipe it that way and reinstall the firmware but that is a extreme I would only do in a worst case scenario.
If anyone has any idea's I would appreciate it this isnt my first rodeo with android devices I am not a complete novice I have rooted my phones in the past including my current galaxy s4 so I am open for any and all ideas.
Thanks,
West

Yea I am aware of that part my problem is I keep wiping the tablet and restoring to factory and within a couple hours it tells me it has full memory or low storage space again.
I went to the extent of deleting the non needed folders such as downloads images dcim etc and letting the system remake them assuming they were the culprits I also went into the Android\Obb
and also Android\Data and cleaned out the stuff that did not need to be there on my last factory restore.
And No matter what I do upon resetting back to factory the space gets consumed within a couple hours and that's only just browsing the web and clearing the cache when done.

hi, if you have a large amount of pictures/video, it may be gallery
generating/regenerating thumbnails in /sdcard/DCIM/.thumbnails.
Check the size of that directory, if that's the case delete the directory and replace it
with a dummy file named .thumbnails an set it's permissions to read-only
i ask because if your moms got hymns etc. that are actually in an image format instead of text
those will have thumbnails, the same with some ebooks.
Replacing .thumbnails with a fake .thumbnails will only make gallery run a little slower.
Many apps do the same thing, generating images in hidden folders on your sdcard for caching ads etc.
