Hi as title says I want to know how to transfer files propelry while booted into android kernel.
For example when you plug in your phone vai USB and use as card reader I can easily transfer files to and from but the problem is that when I unplug and go to view these files on phone the file system hasn't updated and I cant locate them on card.
Ive tried the unmount feature aswell as a hot reboot but nothing. Only way I can seem to do it is to power off and then boot back into android.
Is there any easier way or procedure that I need to follow?

best bet is to load the files in winmo then boot into android
Dude that wasnt my question, obviously I can do that, thats not the point.
My question was the best way to transfer files while booted into android, if it possible then obviously booting into windows and back to android every time you want to move/access files isnt the "best" way and its inconvient.
I appreciate your reply but your answer was irelivant unless its the ONLY way which I doubt (well hope)
Does anybody have a solution?
As of now, the only good way to transfer files is indeed through WinMo (or with a MicroSD USB reader, with phone powered off or in WinMo). Most Android builds support USB Mass Storage, but I haven't heard of one that handles it perfectly (which isn't too surprising, considering Android runs -sort of- from the SD card).
So in short, no there is no other way at this moment that I know of.
Edit: There is a way: through WiFi! There are some applications available on the market that turn your phone into an FTP-server, I use Websharing (Lite) for this. They don't need an unmounted SD card, so they'll probably solve your problem.

Yeah I was thinking more of teh same route, Ive been using drop box for the moment but FTP server would be much better.
I was hoping there would be a solution to been able to access teh files that have been sent via mass storage mode but this could be just as good.
thnx for suggestion.
This is not a quickfix, but I was frustrated with the same problem last night when I was trying to locate the files that I just transferred to the phone. I noticed that unmounting, and remounting doesn't refresh the folders in the system. But I managed to find the transferred files after unmounting the sd card, and then browsing to the root sd card path instead of the mounted partition.
So, instead of mnt/sdcard/ you should look for the files in /sdcard after unmounting the card. See if that works, at least it worked for me last night.
Use droid explorer
ok i'm using taboonay 2.0 with Thor's 3.0 kernel. I can see all the files on my SD card through root explorer and if i take the card out and hook it up to my pc. My question is why when i plug my iconia into my PC i can see the card, but can't see any files on it? Wasn't 3.2 supposed to fix this or it something on my end? haven't tried to reformat it cause it isn't a big issue to me just trying to figure out why.
i have sorta similar issue. I can access sdcard in root explorer or other apps, but if i pop it out it get interesting. I can still browse the sdcard contents in any file explorer even though i am holding it in my hand. Also i have not been able to access the sdcard from the latest clockwork recovery. The only directory there is LOST. So i take it to the pc and same thing, only the LOST directory, pop it back in the tablet, fire it up, browse to /sdcard directory, all the files i have downloaded are right there still along with that LOST directory......
So i cant flash anything now. Tried reflashing CWR from the Acer Recovery Installer, no progress. Tried formatting sdcard on pc using the tool in the sticky, same thing, cannot access sdcard in CWR.
Help.
**update: so here's what i found, apparently there is a directory called sdcard on my tab that is actually local system memory. It has all my downloaded files in it. I mounted the tablet with USB to my pc and moved one of the files to the sdcard(which is empty by the way, everything is going to the local ram for some reason) and rebooted into recovery and then it showed up in CWR!
So all this time my tablet has been syncing my google music beta music for offline use, around 10 gigs of it, and it dumped it all on the local memory so now im almost out of ram.....with an empty sdcard.....great
I believed you guys are having this same problem...please see this thread about directory naming structure...etc

You could transfer the files via Dropbox, the link below in my signature will get us both extra storage space.
welll i can copy but they r not visible or getting deleted ......
Are you copying the files to the sdcard? And what app are you using to browse for them once you have transfered? Root Explorer is the best file explorer imo.

Are you removing the usb device safely?
Usually if you copy files to the SD on android they will not be visible until you restart the device. You can make the media files visible using some apps, but other files will only appear after you restart.
Apparently, when copying files using My phone explorer, the app seems to make android update it's information and thus files you copy using My phone explorer will appear when you finish.
I have tested this with most sense builds, but not with Amercian Android.

This is false.
When you copy anything to Android's SDCard via USB/WiFi, the device immediately sees the files.
When you copy media files (pics/music/movie), the device sees the files, but the Media Service might not have indexed the files yet, so media apps relying on the Media Service will not show them (Music app f.e.)
IF you're copying files to the SD card via USB, safely removing the device from your computer, and they still do not show up on Android's File explorer, then i would check your SD card for errors...
P.S. Tested on HTC Kaiser running froyo/gingerbread, HTC Diamond running Froyo/Gingerbread, HTC HD2 Running gingerbread, HTC Desire running Gingerbread, HTC DesireHD running froyo/gingerbread. Multiple SDcards raging from 1gb to 16, class 2 to 10.
With americanandroid on SD, Theres a problem with usb files transfer (check FAQ'S on thread), u can do: reboot to wimo, copy files and boot android, files will be there, OR use the program for windows described in the FAQ (guess its Androidmanager) OR.. Use NAND Rom... ;-)
Hope it helps

I like that you tested it on multiple devices, but they're all running Android form device memory if I'm correct, right? you're not running SD Android. anyway I tagged a long and scanned my SD for errors and nothing was there. Using wifi and bluetooth makes android recognize the files, and yes media files have to be reloaded.
however, when copying non-media files through USB on several build I've tried before (can't remember which because I've tried almost every SD build out there) the phone will not see them even using a file browser, but they would appear on the PC. Resetting the device would make them appear. My only explanation to that was that certain builds would create some kind of "image" of the files on SD at the time, and would show you that image when you request the files. So if you add files using a way that doesn't update that image (here copying through USB) they wouldn't appear until the next start.
try samba filesharing from market.
you can copy files via wifi without usb.
Or you could use a card reader......
dropbox is great for transferring files wirelessly too

HTC Kaiser run android from sdcard (either SD partitions or image files on the main partition) long before there was nand.
I understand what you're saying, but i cannot accept it. It makes no sense.
Let's see, Android requires a minimum of 2 partitions, one for data, one for system. Those might be a SD card partition (in this cases), or 2 files on the SD card mounted using loop.
IF, you're using the second option, you cannot access the sdcard on the computer (it must be unmounted from android to appear on the computer, you probably noticed that it's impossible to access the sdcard when it's connected via USB as mass storage.)
So, you're probably using SD card partitions. Am i right?
it might be permission issue...

sorry didn't notice the Kaiser on that list. I don't use SD partitions, too lazy to do so, and I don't unmount the SD, had my share of troubles doing so in the past, I used apps like Dualmount SD and such, media files would appear after I force android to rescan media, but other file types would appear after I restart the device. So I came up with the best possible explanation. However, when I copy files with My phone explorer they always show up, whether media or not, could be the new build I'm trying, or could be that I'm doing something I didn't in the past, who knows.
I have a new A500 that I purchased yesterday from a large national retailer. The A500 was the last one in the store (i.e. the display model).
I have not been able to flash a new ROM to replace the existing by using a microSD card. I have tried different versions of the update.zip file on different microSD cards to no avail.
The tablet will boot into recovery (PWR and VOL-) and starts the process (I get the "opening package" screen with the green robot) but quickly that turns into the "Triangle-Exclamation" screen, and the existing ROM is unchanged. I can just reboot back into the existing rom.
I have been able to use an executable EUUS file to replace the "DEMO" system using a USB cable from my PC, but the sdcard version of the update will not work.
My suspicion is that the bootloader is somehow different on the Demo models, but I don't know for sure.
Any thoughts or ideas?
i know this happened to me when my sdcard wasnt in the right format i had to use ubuntu and format it top a fat. not fat32 just fat and worked fine afterwords
Thanks for the tip, I'll try that. I think you may be on to something because I get the exact same process if I try to boot into recovery with no sdcard at all, so it's like the tablet isn't seeing the sdcard when it is present.

If formatting the sd card in linux/ or another Android phone does not work. Try a different sd card. This has been a issue from the beginning of the iconia with some sd cards. and its random.
or if you are as daft as I. When you rename the zip file just rename it as update not update.zip. Then right click - properties - details and you will see it named as update.zip.
When I renames it first time as update.zip then under the details it was named as update.zip.zip

HA! That's happened on about every known device thread at one time or another. You can fix this by changing the Explorer folder options to "display known file types".

Great. Now my entire virtual SD Card has been wiped! Don't delete the storage directory in the root of your virtual SD Card (/storage/emulated/0/) or (/storage/emulated/legacy/). Watch out!
Now, I'm wondering if I can somehow gain access to the files if I recreate this folder. From what I remember, there were a number of nested folders within this "storage" directory.
Can someone give me the dir structure of your "storage" folder? Thanks!!
EDIT: This is how I did it. See post 6. Stay away from your "storage" folder while browsing your phones sd card over MTP at the computer!!!

Hey thanks for that, but I'm pretty sure there was a folder called "storage" in /storage/emulated/0/ (or the same location /storage/emulated/legacy/).
So, what I'm looking for is what the folders are in *that* folder. And it should look something like the following:
/storage/emulated/0/storage/...... <---------- these are the folders I'm missing, and there most likely is a symlink in there. I think if I can just recreate that folder structure and recreate the right symlink there, then I might be able to get my photos back.
Thanks.
You're saying there is a "storage" folder in /storage/emulated/0 or /storage/emulated/legacy? Mine only comes with these 2 directory, and /storage/sdcard0 is a link to legacy.
Now you still have that 2 directory but can't find any of your files inside?
You deleted the storage when hooked up on your PC yes ?.
The storage folder your referring to only shows when browsing your folders via your PC so you could try recreating it via your PC again but I seriously think its gone mate. I accidentally deleted this folder too once but I always have regular backups on my pc.

Yes!!! Thanks for this post! I was indeed cleaning up my "sd card" from the PC (over MTP). And, I noticed a storage folder at the root of the SD card. In fact, it's there right now! If I browse the contents of the SD card on the PC, there is a storage folder there with only an empty "emulated" folder in it. I've never noticed it there before, so I just deleted it. Suddenly, I couldn't access anything else on the sd card from the PC. I thought, that's weird. Sure enough, everything just vanished!!
WORD TO THE WISE: Stay away from that "storage" folder at the root of your SD Card when browsing its contents over MTP!!!!!!!!
why not just do a factory image flash? userdata.img should contain all the folders and locations you need to restore it properly.

Oh, there ins't a problem anymore. I just thought that the "missing" symlinks had something to do with my wiped sd card. But, it turns out that the missing symlinks aren't shown in the default CM file browser, only in other file browsers. They were there all along.
The kernel of the story has been solved as I now know how I wiped my sd card.

There is no way to get the files back, I deleted it once when connected to PC because I didn't recognized the folder and it was empty, so I deleted it. Then I tried for a week in every forum to found an answer, but there is none.
reflashing your current rom or any other rom would have brought everything back to how it should be. a deleted my whole system once, then just relashed my current rom at the time, and all came back.

Oh, I got most, if not all my photos back. There is a great link which shows you how to transfer your entire userdata partition to your hard drive and search for recoverable files. Alternatively, you can also use the app diskdigger and send your pics to your PC using coreFTP or other FTP server. Both methods recovered about the same number of photos. So, yeah, a reasonably good ending.

Not in my case. That's the first thing I did. I thought, it's just a symlink, right? Well, not really. It's not really a symlink on a different partition. Again, it is only created during an active MTP session and ONLY visible on the PC. And, as soon as you wipe these seemingly empty folders, all references to the files are lost, as the system begins to slowly re-populate the space, which is really at /data/media/0.

I know it wouldn't bring your files back, but it would restructure your storage partition properly so you could start from scratch, rather than recreating all the folders manually.

? No one is doing anything manually. Did you intend to reply to me? The missing symlinks referred to earlier have nothing to do with it, as I discovered and reported a few posts ago. Again, there is a "storage" folder at the root of the SD card only visible at the PC when connected over the MTP protocol. When this folder is deleted, all is lost immediately, even by re-flashing a ROM. Hope that helps someone to avoid deleting it and consequently all their virtual sd card files.

Hey how did you do it? Which third party file browser did you use? I have done the same thing..
Check /data/media/ those folders are just linked to /data/media/ anyways. All your stuff should be there unless if you deleted the entire data partition

The problem is that if you are browsing the SD card contents from your computer (while the phone is connected), a folder appears there that otherwise is NOT present while browsing the card's contents from the phone, while the phone is NOT connected. I forgot which folder it is, but I believe it is called sdcard0 or some such at the root of the SD card. I have no idea why it appears, but if you delete it, you have deleted the entire contents of your SD card. And, yes, you have lost everything unless you are able to acquire a special tool to recover the contents, but if you have done so, don't do anything with your phone, as those contents will be overwritten by new files.
In so doing, I had originally thought that there were symlinks that were also deleted, but that wasn't the case. The symlinks were still present as viewable by ES File Explorer, but not with CM's file explorer. In any case, all my files were still lost, but I was indeed able to recover the majority.
Edit. I used Diskdigger in the Play store. And it worked pretty well. The other option is linked in this thread above.

Yes. First, either turn your phone off or do VERY little with it, as those files could be overwritten.
I had surprisingly good success with Diskdigger. It was able to recover most of my photos, although some were a bit "damaged", as in only half of the photo showing, and some other oddities. But, at least it was better than nothing. You will need root access for this sort of thing.

Just one other doubt, if I were to use the link to guide which you posted which allows to mount the VHD as a USB storage, does that allow me to recover other files too?
