I've read somewhere here in the forums that it can screw up the a2sd function
so how can i connect the phone to my PC (because using a card reader every time you need to connect your phone to a PC is @[email protected])
Is this true? any alternative?
I'm using wildpuzzle ROM btw
Hi Dudin.
As standard, when you connect the phone to the pc as a removable storage, Android prevents the SD from being seen by the phone at the same time. As A2SD installs apps to the SD, this obviously causes any Apps on the SD to not work. I dont think its a permanent screw up, as it all should right itself after you disconnect from the computer, but you do have options:
1:Connect as Sync or Charge only. (a quick but pointless workaround if you want to browse your Sd card from the pc),
2: Or do as I do and install "Dual Mount SD" from the market It makes the SD card accessible by both Android and the USB at the same time. Works perfect for me, I can still use my aps and access the SD from the PC simultaneously. (I have used it on Wildpuzzle, Openfire and Cyanogen Mod, Eclair and Froyo versions). You need to be rooted for this though as it asks for superuser permissions.
Hope this helps.
Ok I will clarify for you. If you use dt app2ext patch. When you mount your sd card, the computer mounts the fat32 partition, and does not detect the ext partition, so it does not screw your card up, or the apps.
if you are using froyo app2sd, the apps that are on your sd card will not work when the sd card is mounted.
thanks for the replies
I find a good alternative is Dropbox - and it is mentioned in a lot of threads.
I already used it for work and it is great. No looking around for a USB cable or turning off/remove case/remove card etc which takes ages! Dropbox is free so give it a go! I use it in conjunction with EZ File manager (i think thats what its called) to transfer stuff and unzip archives.
Hope it helps!
I have installed A7Comb rom which mostly does a good job. The biggest problem is that external sdcard and usb are inaccessible. If I choose to go back to 3.01 where I had this capability, access to external sdcard is required to flash the old rom. Am I screwed or are there any other alternatives?
ooorah
im not positive, but if i remember correctly you have access to the external sd (using Root Explorer or something like it) there is /Mnt/sdcard check in there im not sure the exact directory, but im pretty sure it was in there when i was using A7comb, then you can copy and paste the update.zip to the root of the sd
Let me know if you can't find it, i will flash A7comb real quick to give you a hand
Catch-22 eLocity A7
smallba, Thanks for the reply. Can root explorer be used to do the rom flashing? I can get the 1.41 rom on the sdcard using my desktop, but the A7 can't see it. I've tried to flash using the start button routine, but it never recognizes the sdcard and sends me back to boot. Then I cant boot until I remove the sdcard. Also, even though I'm rooted and have superuser, root explorer always fc's. What a mess.

Do you have Sdhc adaptor physically plug the micro sdhc in the computer and then move the update zip to the sd?
What kind of sdcard are u using?
Sent from my PC36100 using XDA Premium App
Thanks for your reply. At /mnt/external_sd the sd folder is shown as empty.
ooorah
smallba I connect via usb to my desktop using a Targus adapter. The sdscard is Kingston 2gb formatted fat32. I cut/paste update.zip to the sd card.
ooorah
Do you have a cell phone to try the sd card in? I just want to make sure it is not corrupted, you have flashed before using this same sdcard?
Sent from my PC36100 using XDA Premium App
Yes I've used this sd card to flash on my Acer A500. I'm sure it's ok.
ooorah
What does it do when you put in and pull out the sdcard?
Sent from my PC36100 using XDA Premium App
When sdcard is installed I look at externai_sd and it's empty. I cannot reboot until the sdcard is removed. BTW, various mount apps I've tried fail to recognize the presence of a sdcard.
ooorah
I know I been asking many questions, but it recognized in the accer?
Sent from my PC36100 using XDA Premium App
Yes, sdcard was recognized in Acer 500. Content was shown under external sd.
A7
What rom are you trying to flash back to?
I had some issues reverting back from A7Comb.
I think I had to flash back to stock first.
Re: your previous post, how can I flash back to stock if I can't find external sd?
ooorah
Cant read SD
I reloaded my copy of A7Comb and will play around with it to see if I run into the same issue. If the SD can't be used, it may be possible to connect via USB/ADB and push the stock images.
However, I have never used ADB with the A7, only with other devices. I will also try and figure that out to see if that's a viable option. Will need to find the drivers and get those loaded. Been meaning to test ADB with this device anyway.
Thanks DANO, I'd appreciate the help.
ooorah
I'll do what I can, I'm no expert, but I am very comfortable with ADB and have no concerns about messing with my A7. I've been meaning to do this for a while anyway. Will probably take me a few days to get get the A7 connected to ADB as its USB port doesn't play nice, and there are some tricks to getting windows/ADB to pick up the device. I'm also gonna try and lookup Dexter to see if he can give me some tips on doing this.
I used ADB last March and rooted my CRUZ 7" tablet. Whether it will work with a usb connection to eLocity A7 will have to be tried. I'll play around to see if I can get it working. If I get that far I'll have to wait for further instructions.
ps I can use a usb keyboard with no problem. ooorah
Yeah, keyboards, thumb drives, etc. should all work as the A7’s USB slot is set to host mode by default. The trick is flipping the switch to slave/device mode so we can use ADB to communicate with it.
Dexter’s A7Comb Rom had an App “OTG” for doing this (with a reboot), but when I tried it out, my Windows 7 box only saw the device but still didn’t fully communicate with it (ADB didn’t see it at all). Most likely due to the lack of a driver, or rather telling it where the driver was.
I’ve got some info on doing this, and I plan on trying to get this up and going tonight. Once I get ADB connected to the A7, I would think we should be able to push a new recovery image or something along those lines to fix whatever happened with the SD Card.
Just curious, have you tried a factory reset, data wipe, etc. (then reboot back into recovery), and tried to run the update.zip from the SD Card. I doubt this will work, but the A7 re-writes the recovery image with each update, therefore if something got corrupted, perhaps a wipe will fix whatever is broken in recovery by way of re-writing it. I’m not sure if recovery gets replaced with just a data wipe/reset, but if you don’t mind resetting your device it might be worth a shot.
I confirm it!
1 format your mocro sd on nfts using wimdows 7
2 insert the card in your 7.7 and dont care of the tablet says that the card is invalid
3 launc mount drive that is free on android market
4 unchek device filtering
5 select the last bottom drive that is the only one nfts drive avaiable
6 tap the upper right button, the one that have the icon of a drive
7 now you should see in the right colum your drive with a bar thar rapresents the free space, if you cant see this, reselect the nfts drive on the left colum and retap the mount drive icon (upper right) until you can see the drive mounted on the right colum.
8 when your drive is mounted you can find the drive folder with a root enable file manager like honeycom fm hd, the folder is under the system folder named mnt
Tht is all it works fine amd you cam close the app drive mount, the tablet comtinue to recognize the nfts micro sd wothout the app running. Now i can put my hd movies larger than 4 gb inside my micro sd and play them with my 7.7
The only problem is that tje sistem apps are setted to save thinks in mnt/externaldevice, so if you want save you movies or photos taked with the 7.7 camera inside your microsd you cant do it, you have to move them from your tablet memory to your microsd nfts using a file manager, but this is a little problem nothing of big
If any brave user is able to tweak the camera app to save the moviesnor photo inside the path mnt/nftsdrive please do it, after this all is perfect. Thanks
thanks!
btw, it's called NTFS, not nfts
Yes you are right, i do ever this mistake xD
Do you need to root your tab ?
Yes root is needed
Thanks.
I got it to work.
But there is a problem.
How can I transfer a 6 GB file to my 64 GB SD card using usb cable connected from my desktop to the Tab 7.7 ?
Currently I have to take out my SD card from my tab and using an adapter to transfer the movie to it (from my desktop to the SD card).
This is a tedious process and I don't want to keep taking the SD card in and out of my tab. I want to transfer my big movie file straight from my PC to the tab when it is connected via USB cable.
Currently, when I connect the tab to my desktop, I only see the internal storage of the tab and not the external NFTS sd card.
yes i know, this is a big problem, but unfortunatly i am unable to solve it, becouse the sd is mounted in a different place,in the origins the card id in mnt/externalstorage, but with the app drive mount tha parh is different..

perhaps softlinking the path may help?
it can help, but how to do this?
Maybe by transfering from your desktop to the tab using Samba through your local network (ie wifi instead of USB) and a SAMBA app on the GTAB ?

Yes i know this method, but this is only wifi , it is more slow than usb. To do this just install astromanager and configure a spb network with the ip of your computer, after this share a folder from your pc and then you can copy files from your pc to your tab microsd via wifi
I've just made an app to mount NTFS sdcard.
It allows you to use it like normal FAT32 sdcards,
working with Stock camera app or MTP file transfer.
Could anyone try this?
I'm going to put this to android market
and I've already purchased a developer account,
but it seems to take some time to be able to upload my app...
My English is not good, I know
If there are any weird wording, let me know.
** alpha version **
** only for root users **
** only for Galaxy Tab 7.7 ... for now **
This app is to mount SD Card using NTFS.
/mnt/sdcard/extStorages/SdCard is the root of sdcard.
Auto-mount when the Android OS starts.
Or you can mount/unmount it manually.
** Not Bug **
- If you don't do "Safely Remove Hardware"
when you take your sdcard from PC,
it takes some time to mount it.
** Confirmed Issues **
- Only NTFS sdcard use assumed.
This app may prevent using FAT sdcard.
- Once unmounted, even after you mount again manually,
Android OS don't detect the sdcard.
You can access it with file managers or other apps,
but stock camera and settings app don't.
(Let me know if you know any solutions for this.)
- At the first attempt to mount (and get permission for su),
Android OS could fail to detect the sdcard.
It may be caused by delay of Superuser asking if it's ok or not.
- No error handling
** Disclaimer **
I am not responsible for any damage caused to your device or data or feeling.
It is recommended to backup your precious data.
Perfect app!! it works fine.
For this point
- Once unmounted, even after you mount again manually,Android OS don't detect the sdcard.You can access it with file managers or other apps,but stock camera and settings app don't.(Let me know if you know any solutions for this.)
It is not enought to restart the device in order to let android and camera/gallery to recognize the ntfs card ? This will solve the problem?

Thank you!
Of course, after rebooting the device,
sdcard can be mounted and Android OS detect it as usual.
It seems initial booting and inserting sdcard trigger detecting process,
but I don't know how to let the os to do it by my app.
dont worry your app is awesome as it is it is not a big problem to reset for make it functional after the unmount, just specify it when you sell in android market. Thanks so much for the app
Pretty great app to bad i left my 7.7 at home once i get home this will be the first thing i try. Btw any plan for galaxy note ver too?
Thanks alot

I think it's possible to improve this app to work on galaxy note,
I don't have one though.
All I need is sdcard's mount point ( "/mnt/sdcard/external_sd" ? maybe ) and
device name which is like "/dev/block/mmcblkxxx".
If you can get these info, please pm me.
Thanks.
Thanks for awesome apk~
If you have any plan put it on the market, plz let us know.
We will support it!!
please hurry up if you want to gain money, becouse the huawei media pad woth ics of my girls can read ntfs micro sd, i think that with the ics update the p6800 will read the ntfs from defoult.
Hi!
I recently installed the triple boot ROM and I have a few questions!
I am using a 16gb Class 4 SanDisk card.
1. After burning the image to the card, it reduced it to 100mb usable space. I resized the /sdcard folder to 12gb. Is there a way to access the /sdcard folder from my PC? Or should I transfer files via USB connection?
2. My home screen always defaults to landscape mode and it doesn't rotate to portrait at all. I wanted to flash an update but with my PC only showinging the 100mb /boot folder, updates don't fit since they're too large.
3. When I want to add updates, fixes and nightlies , do they get placed I'm /sdcard?
I'll have more questions soon but these are my main concerns for now. I'm an old school Android ROM flasher from the ancient HTC Elf days, so don't mind thr noobiness!
I just really want to be able to store pdf's onto my SD card and access them & also have my home screen rotating properly. Then my Nook will be near perfect!

When you say your home screen only shows landscape, I'm assuming you mean in CM7. Go to Cyanogenmod settings and choose display and make sure all rotation boxes are checked. Also make sure in normal settings that autorotation is checked.
You cannot see your sdcard partition with the card plugged into the PC. It only will show the boot partition. You must use USB connection to see sdcard. And you always place the update zips in sdcard (not boot) since Racks has modified his CWM to look there.
If you look at my tips thread linked in my signature, I have an item (B8) that describes the difference between verygreen's SD and Racks' SD. They are very different on how you install new roms.

Hi leapinlar!
Thanks for the quick response.
Luckily, CM7 works perfectly on my Nook. It's CM9 with ICS 4.0.3 that my homescreen and app drawer is stuck in landscape. It doesn't seem to rotate at all even with auto-rotate checked. When switch to the homescreen from an app that's in portrait mode (ie. Flipboard), it automatically rotates the screen back to landscape when it switches out to the homescreen.
Will be doing more research on it, but haven't had any luck finding a fix for it. *crosses fingers*
Well, same suggestion. Go to settings, display and make sure all of the rotations are checked, along with autorotation being checked.
EDIT: OK, there is one more setting in CM9. Go to accessibility under settings and there is one more auto-rotate setting there. Make sure it is checked.
T-Mo S2, took the nougat update, and even using "MyFiles" all attempts to write to the external sdcard fail. I can't even enable permissions for root explorer or es-filemanager pro. I'm frustrated enough to use this tablet as a weapon in a road rage incident. Anyone else seeing this or is there something I've missed along the way?

I have difficulty to write on SD card for some of the apps (such as GPS) after update. But, the file explorer and some other apps are ok. I believe the problem is caused by app permissions and needs to be solve as per app level.

It just a permission. It will pop up with permission request then you choose internal or external at root of storage. My can read/write from internal, microsd card, and even 1tb WD hard drive (without power) all no problem.
I'm having the same problem. I was running stock to this happened and have since rooted and tried two, (at the end of the day not very) different ROMs. Resurrection remix and Lineage OS both running nougat and neither have worked. I've tried using adb partition without success and root essentials asks me to flash ASPlugin.zip which I have tried with the flasher and through twrp. Neither works as it asks me to flash it again when I retry root essentials. No errors get thrown while flashing ASPlugin.zip.
I'm also at the point of wanting to throw my tab against the wall.
The permissions window pops up but it does not seem to effect the external SD card.
this link shows how to fix it:
https://www.youtube.com/watch?v=VJRKuQf0puE
ES File Explorer Pro permits root permission, but it's not very obvious as to how it works. Execute a copy or move, you'll be prompted to go to the root of the card, click on the card link, then bottom right hand corner, click the select button and it's done.
Hi everyone.
I found this thread while searching for an answer to the same problem, which drove me almost crazy, too.
I decided to post my solution here, so that it might help others in the future.
As I said: I had the said problem, too.
No writing to ext. SD card, also no writing to my USB-stick via USB-OTG (On The Go), after updating my Tab S2 (SM-T815) to Nougat (Android 7.0) with a stock ROM and then rooting it with magisk (which btw went surprisingly well!).
I am using FX File Explorer, bought it even to be able to use it as root explorer, imho it's one of the best ones out there.
Connected to my PC I could pull or write files to my internal storage as well as to my external SD card via MTP, though.
Strange, but to those of us with just enough know-how to not brick the phone when flashing "stuff" the higher functions seem to be magical anyway, so I didn't take too much time to wonder.
I tried unmounting and mounting both SD card and USB stick, but that would not help.
Also disabeling writing acces in FX explorer and enabeling it again showe no effect. All I got was an error message "Internal Error".
The post above gave me the hint about permissions. (I couldn't watch the linked Youtube video, because my PC has no speakers atm, and I also had no headphones. Also, it looks like the video solves an intirely different problem anyways, not sure why tensux posted this here!?)
So I checked the permissions by using FX.
I went to /root then checked the permissions for /root/sdcard which were set to rwx,rwx,rwx.
Then I checked the SD card (and the USB, while I was at it anyways) via root/storage/[technical name of my SD card like 5555-2843] and /root/storage/[technical name of my USB-stick like 2234-1289] and found that both had their permissions set to rwx,rx,rx.
I marked the respective folders, went to security through the context menu, and changed the permissions to rwx,rwx,rwx in each of them. It would not stick in the grafics, meaning afterwards the permissions still showed no change, even when I restarted the Tablet, but...
I went back to the regular FX explorer and unmounted and mounted both SD card and USB-stick again. I still got the error message, only this time I tried to copy, move or delete a file there was no problem anymore, neither from or to the SD card nor the USB-stick.
After several restarts I still can write to my SD card as well as to my USB-stick, so I must have done something right.
.
Thank you XDA for being a place of knowledge, maybe I could give back a little and maybe this report helps someone else out there.

All external storage write permissions are granted on a per app basis as per Google's security specs.
If an app has issues with writing to external storage then it is the app at fault.
The developer needs to update the app with the new permissions.
I have many Android devices and for all of these devices I use Root Explorer.
This is and has always been the best Root file explorer since day one. It does what it needs to do without any silly unnecessary bells and whistles.
Any serious developer will use this app as it's proved to be the most reliable and the dev is on the ball with this app.
Never have I had an issue with it.
