[Q] Some apps can't see/access virtual sd card - One (M7) Q&A, Help & Troubleshooting

Hey forum,
so my issue is this: Recently I installed a custom ROM (Android Revolution HD), because my m7 was soft bricked (stuck at boot logo) after an update of the original ROM. Some applications can't see or access (probably can't write) the virtual sd card while others can. For example, I installed the zedge app and it can't preview and fails to download everything, then I check the virtual sd for the zedge folder and of course it isn't there. Same thing happens with the internet browser application of HTC. When I try to download any file, it reads a message "An SD card is required to download "name of file.xxx". The same issue appears with many other apps. Nonetheless, other apps can access the sd card with no problem e.g. when I download a file with ES Downloader everything is fine. It also mounts just fine as MTP device on PC. Viber and many other apps also work fine and have their own folders in sd card. I searched all around for solutions and found plenty but none have worked for me. The weird behavior to me is that some apps work like a charm with virtual sd while others fail.
1) Downloaded the "FolderMount" app. Some people suggested that the app would recognize some issue with the permissions and attempt to fix it. It didn't find any issues for me (Root was granted to the app).
2) Downloaded the "Fix Permissions" app. Aligns UIDs successfully but no results for my issue (Root was also granted to the app).
3) How to: Fix no access to the virtual SD card after Android Lollipop update --> I tried this repair process from Android Revolution HD blogspot, everything happened successfully but still didn't solve anything. (Sorry I'm not allowed to give link, it's my 1st post)
4)How to: Unlock external SD Card writing for all apps in Android 4.4 and 5.0 --> I also tried this process from the same blogspot as previously. No luck there too. (I used the "sdfix" app as well which does automatically the process explained in the blog, just in case I did something wrong, no luck of course).
5) I tried the ViperOne ROM still the same issue.
I have run out of ideas what else can I do and it is like I have half of a smartphone.
Any help would be appreciated.
Thanks

Bandswitch 2.4.1 just says install was unsuccessful as I click on the cab
Mobile justice - same thing, even after installing certificate
EDIT: another one on the list Reperion same issue as Pocket CM
EDIT #2 Looks like its a problem with either my Storage Card or Transferring to it via Activesync
I have tried moving the cabs to the device and install (instead of the storage card) same thing.
Tried after soft reset..same thing
At first i was going to just go into the individual threads for help, but since its now 3 programs, something is wrong
Trying to see if i am missing anything before doing a hard reset.
Any help would be great

[Q] CM7 and Nook App

I am having a problem with the Nook app on CM7 (using the 4th nightly and the OC kernel.)
Doing some quick searching and extensive looking hasn't yielded any results directly related to the following issue.
When looking in my library, if I try to download a book it just says "No such file or directory" and my other books that are on my SD card don't show up/can't open them with the app (No Application Found).
So, just wondering if anyone else has got this working, I would really like to use this as an e-reader.
Thanks
Ran into the same problem last night

Tried that solution and it doesnt work when trying to download books. I always get file type not supported. You?
yes, it does work when downloading books. make sure you follow it exactly.
you have to set the EXTERNAL_STORAGE value to /sdcard like it says and NOT /mnt/sdcard

I did change that but I didnt notice that I had to type out adb shell before typing su for the apk. I get permission denied, does that mean I missed something while rooting my nook?
Edit:
NM adb shell works, just didnt work from terminal emulator. Anyways tried everything from adb and a computer and still no dice. I have no clue why this is not working. The books in my files dont have the cover and when I click on it it looks like it will load then just goes back to my files again.
NM, it seems that the books that were already in my library from when I had the regular nook OS was giving me issues. I went to shop for a new free book to see what happened and it downloaded and worked. So I did it right from the beginning but kept trying the same 2 stupid books. lol Thanks
I'm not sure what's going on here.
I tried following through with the directions posted in the link. But my adb shell seems to be repeating whatever I type after I press enter. It doesn't seem to be working.
Is there something I'm doing wrong?
I'm using phiremod.
Okay, so I found something... I think.
I did export EXTERNAL_STORAGE /sdcard
and I got
export: /sdcard: bad variable name
Any suggestions?
WORKING Nook ereader app on Nook Color running CM7 from sd card
I wanted to be able to have access to 2 barnes and noble libraries on the same device. I looked around and this is what I came up with. You don't need to do any really tricky or invasive mods and it works great. I'm mostly a moron so I wrote this for people who are like me, please don't be offended if you have to say "well duh" alot.
I would read the notes at the bottom of the post after you read this.
1. I prepared a CM7 sd card with google apps!!! using this method:
http://forum.xda-developers.com/showthread.php?t=1000957
***(I used the stable CM-7.1.0-RC-1-encore-signed version + current gapps, but it should work with any current CM7 nightly)
2. I powered down my nook completely, inserted the CM7 sd card, powered it back up, and let the CM7 installer routine run. The installer shuts the nook off when complete, then I rebooted into CM7. After registering to my google acct and getting to the home screen, I clicked on the icon in the bottom left corner (3 little horizontal lines) and selected Settings>Applications>Unknown sources...check that box.
3. Opened the Market app. Searched for "appinstaller" and installed AppInstaller by FunTrigger. Then I completely powered down my nook and removed the CM7 sd card.
4. Then I downloaded an older version of the Nook ereader app (ver 2.5) and put it somewhere in my filesystem that was easy to locate (you will be locating it from linux) from here:
http://www.freewarelovers.com/android/app/nook
5. Then on a PC running Linux (ubuntu 11), I plugged the sd card I put CM7 on into my computer. In linux you can see all the partitions...in windows all you can see is boot. I opened the "CM7 SD CARD" partition, and I put the nook.apk file I downloaded from freewarelovers right in there.
6. I reinserted the CM7 sd card into my nook and booted it back up. I went to applications, ran AppInstaller and clicked on the "nook.apk" icon and installed it. Registered my B&N account normally and populated my library.
Notes:
* DO NOT add the nook.apk into the native OS. This is only for CM7. If you try to add this app to an OS with the native nook reader working (unrooted/nootered) the device gets stuck in a boot loop which you will have to use CWM or 8 fail boots to recover from.
* I bear no responsibility for any damage you may do to your device by using this method. That said, it is almost impossible to brick a nook color, especially using a sideload OS. If you think you did just look around the forums, there is lots of information on how to unbrick a nook color.
* If you do not have Linux running on anything to read the CM7 partitions, you can google "reading ext4 filesystems in Windows" and figure out how to do that. Mac is Unix based, so maybe you could use a mac and just hope no one finds out. I highly suggest you just make a live CD by following the directions here:
https://help.ubuntu.com/community/LiveCD
* Incidentally, you can use this method for sideloading any apps into your sd-based CM7 environment.
Why would you need to sideload the Nook app? Is it hiding in the market these days??
No it's there but you can't download it. Either says invalid device or it won't give you the option to install at all.
EDIT: I updated to a current nightly and it allowed me to download the ver 2.6 Nook reader, but the sign in screen is garbled and it won't communicate with the B&N servers. Had a similar issue with Netflix, which I also sideloaded an older version of and works well.
@ mastigia.
Firstly, very appreciate your effort and post instructions for others.
Secondly, why would you want to go with that route?
At least, there are 2 options installing Nook App with ease.
a. Download and install directly from Market. (see note 1)
b. If for sideloading, just use usb cable to tranfer the .apk over, no need to remove the uSD then insert into Linux just to copy the file.
Note 1: If you can't see Nook App on the Market, then fix your Market first.
Note 2: another option (would be 3rd) is using ADB (either over USB or wireless to push file over)
why oh why

Ok...
a. I CAN see the app on the market. The app currently available is ver 2.7 which from the previous build of CM7 I was using had "Incompatible Device" where the "Install" button would normally be. So, I updated to CM7 nightly 209 thinking I was an idiot. And hey, whaddya know, that made it possible for me to install the 2.7 reader from the market. But it was garbled and would not communicate with the B&N servers and caused me some really crappy synching issues later which I won't go into here.
b. This is just for getting the nook.apk onto CM7 loaded on an sd card. The prob with just moving the file over usb is that windows (which I started off using) will only pick up my native emmc because the sd card partition I want to move the .apk to is in an ext4 partition. Using adb wireless I was unable to find the mount point, once again probably for the same reason.
So, to clean that up I would say just plug your nook into linux and move the file over usb and that would probably work and thanks for the suggestion, I just did not think of that.
Ya know this is kind of a silly and unique issue. I got my gf a nook color, she wants her own library and an unrooted nook (warranty). She also wants access to MY library (which has alot of books she would like to read) and apps like netflix (which also requires a legacy version). Books are the primary reason we got nooks. So for someone like ME, thats the post I would need.
Anybody having force close issues with the latest Nook app? I'm running 213 and I can download but anytime I try to open anything I get a force close.

[Q] Cannot copy anything from PC to mob, cannot even create folders in int-sd

Hi,
Just unlocked my device (xt1068 lollipop 5.0.2 stock india) and rooted it today and changed boot logo.
Everything was fine
Then installed xposed
everything was fine
then i was trying some modules and then when i tried to copy from pc to internal sd i got error(roughly saying your The device has either stopped responding or has been disconnected) (skip or stop copying are two options)
cannot even create folder on internal sd using es file explorer.
tried even in safe mode -->>no luck
Please help.
I have restored back to stock and everthing is working as it should.
SO i request moderator to close the thread

apps (installed on sd card) icon disappearing after restart

I were searching a lot about this problem and some people saying could help link2sd so I installed it for not working for me or I dont know to use it (create link option doesnt made norhing)
I observed this after installing cyanogenmod 12.1 so I am not sure if the ROM causes it or is Fire device...
do you know any trick to solve this?

Without further elaboration Link2SD (or other app/method/tool that leverages symbolic links) is the best solution. You will need to invest time learning how to prepare the SD card; see FAQ below. Otherwise probably best to leave most apps in internal storage unless the developer explicitly states it is movable. This is a generic Lollipop limitation unrelated to device or CyanogenMod 12.x.
http://www.link2sd.info/faq
Some prefer the (unfortunately named) Apps2SD app by Vicky Bonick which offers similar functionality.
I am understanding that is needed first preparate sd and after that click on the option 'create link', and must work all fine. I am going to investigate more, thanks!

Question [SOLVED] Write access to Ext SD Card, Denied !!

Hi All,
Day by day, another MIUI quirk/challenge... Things that were easy and possible under other phones and stock Android versions seem ever so more challenging under MIUI....
So, I purchased a nice 128GB SD Card to go with the built in storage. Mainly for moving data around, so don't loose it...
However due to Android 4.4 and beyond, Google make it difficult to write access this. However other File Managers and Android versions in past, I've managed to re-enable this. However with this phone, so far I have not found to a way to unlock it yet??
The usual app (FX Explorer) doesn't work, says I can't unlook the root of the SD Card, only individual folders... which it then complains, isn't the root.... (yeah, I know that... you wouldn't let me unlock the root of SD).
I try MIUI Storage settings, but that has nothing in there to unlock it....
I then install Google Files, as strangley a guide says that'll work... it doesn't....
There was then a guide with the stock Xiaomi File Manager to unlock write access to SD Card, yet the options in the guide don't exist in this version. And can't see how allowing access to my Contacts in File Manager and then clearing the settings would fix it anyway?
So now running out of idea's to allow access to SD Card... T'was so simple on other Android devices.....
Cheers, Lister
Update: Seems I am not alone, many have this bug and looks not to be fixed.... or consistently fixed. Very hit and miss....
https://www.reddit.com/r/miui/comments/joxuhi
The plot thickens.... or not, so it seems !!!
So under Developer Settings, there is an options to "Force Write Access to External SD for all Apps" so I have enabled this and it has done..... diddly squat !!!
What's the point of providing an SD Card slot, with no write access...??
Lister
Hi All,
Has anyone had any luck getting an Ext SD Card to be writable between apps....?? As all the usual methods that I know of, and apps (FX) that have worked in the past, don't work.
The OS built in settings don't work, and the hidden Developer Settings to force write access don't work....
So at this point, I am racking my brians why Xiaomi even bothered to include an SD Card slot, as currently its pointless and redundant !!!
I'm having to copy it from the Internal memory, onto PC, then from PC back onto Exteral.... and it's slow as hell and doesn't always work... It's a brand new SanDisk MicroSD purchased from large retail store... So not like its some iffy thing off eBay.
Cheers, Lister
Thats, lets say, weird. i never had that problem, try finding something in the developer options?
if nothing worked, then root your phone i guess
Yeah it's very weird, I've never faced this issue on any of my other phones in the past.... Which have mainly been Samsung's.... S2, S5 and Note 1.... All old and trusty models, had no issues with those phones over the years, they were like TANKS.... just kept on working.
However this phone, I am encountering issue, after issue.... things that worked like stock/standard under normal Android are not working on MIUI.... I can't even get Ringtones to work, just have the 3x ringtones it comes with with no option to add more....
SD Card won't allow me to write at the root of the card, it says create a folder from the root of the card and then make the folder writable. I do that, then the OS complains this isn't standard practice and that I should allow the whole card.... which was what I was trying to do, when it tells me "for my own privacy" not write at the root level... Argghhhhhhhhhhhhhhh !!!!! lol
I am trying not root the phone itself at the moment, as this is the most moddern and recent phone ever purchased and trying to run it as stock with banking apps.... But if pushed, I may try rooting and try masking root at a later date....
But for now, if there is any official non-root ways of making the SD Card work, would be grateful...
Cheers, Lister

Yeah the root of the sd card is not allowed a lot of phones, i have a lumia 530 (windows phone) and don't have full access, but my huawei p smart 2019 has root of the sd
Hi All,
Just gets better and better..... NOT !!!
Xiaomi why the fook have you included an SD Card reader to your phones, and Google why do you allow the user to VIEW but NOT use additional storage? Might as well remove the SD Card slot and add a 3rd SIM slot.
Then rebrand Android OS to Google-iOS, and continue to lock this sh*t down !!! Utterly pointless....
Google Issue Tracker
issuetracker.google.com
So it seems this is a known issue since Android 11, getting worse in 12 and dread to think by time of 13. So many unhappy and angry users out there over Googles latest changes... So Google lock their DocsUI storage down to secure their devices, thus users are installing unknown apks to try and re-enable it or ROOT their phones to regain the feature back. Therefore reversing what Google are trying enforce... lol
Pity I purchased a 128GB SD for this phone, might as well slamed in a 2GB for all the use it'll get...

Hi All,
<< Credit, where credit is due... as no other solution all over the web worked... other than below >>
Thanks to @xetc , with regards to this post... Ext SD Card write access has been resolved and can now make use of my 128gb Micro SD Card again... Yaaaaaaay....
Fault: If you're running Android 11, or higher. You will now find you cannot write/make use of your External MicroSD Card as Google have now blocked this. Android 10 is not as restricted, and Android 9 or below is not affected by this issue.
Solution: Download and use FX Explorer v8.0.3.0
To re-summarize steps...
1) If you already have FX Explorer installed, remove it.
2) Then download specifically FX Explorer v8.0.3.0 from your usual source.
3) Then click the top right corner, and select [Enable Write Access] at the bottom of the menu and follow prompts.
4) Once completed, reboot your phone.
5) Now test, to make sure you can write between internal to external, if all good, proceed to update.
6) Now grab the latest version of FX Explorer, once updated, re-check that you still have write access.
Happy days....

Btw, on 4), I didn't need a reboot on A10, just enabled write access, then updated. Your mileage may vary, though, with A11+.

I changed my SD card to another version and my problems were fixed... I don't know if it will help others bud I now associate the problem with my SanDisk as it is not working in my other Redmi
Be aware that when swapping cards, even if you had previously granted card write access, you'll get into the same problem again with the new card. Is it related it to FX not relying on system file transfer app to handle permission, but doing it on its own, instead?
Equally, bookmark links, which are linked to the card's individual path (/####-####/), once you swap card, won't work anymore, either.
Unfortunately, seems none of these and other reported issues seem will ever be fixed, so maybe it's time to move on...
Btw, wonder if this still works...?: NextApp SDFix

thank you also @xetc for reporting the fix first. I was experiencing this on my secondary phone with LineageOS 17.1/ Android 10.
@tliebeck can you revisit the v. 8.0.3.0 code and re-implement the way you enabled media card write access in that version back into the current version? Obviously something got twisted (and has been ever since v. 8.0.3.0 +)
Above all, thank you for your app !!
Not sure why to use FX Explorer. I use Total Commander and it works to the ext SD card fine. (NOTE: Be aware that if you update to the 3.33 version or higher, you will lose the ability to install apps manually from the SD card. Blame Google! You can solve this by signing it with your favorite app (like apk-signer) so Play won't keep telling you there is an update to the program.

The old 8.0.3.0 from December 2020 is now a 7-day trial app, and step #3 does not produce any "enable write access" from the top right hamburger menu. I enabled root/developer access in its settings but no difference.
EDIT: though I see no "enable write access" anywhere the app, I can read and write to it, and send files from it to Drive, the last 2 things fail on my RN11. Both are on custom ROMs on A13. So, this has to be a developer's issue in the ROM, OR something with the card itself. I will keep testing to see what I can find.
i.e. this no longer works (NOTE: this might just be an SD card issue. I am able to write to and send files from an external SD on a different ROM on a different A13 phone - Redmi Note 10 Pro - without any permissions stalls at all using Total Commander 3.31, for example.)

Nope. It produces an error. "Platform permission file is invalid. no groups specified in WRITE_EXTERNAL_STORAGE"

The old 8.0.3.0 from December 2020 is now a 7-day trial app, and step #3 does not produce any "enable write access" from the top right hamburger menu. I enabled root/developer access in its settings but no difference.
i.e. this no longer works (NOTE: this might just be an SD card issue. I am able to write to and send files from an external SD on a different ROM on a different A13 phone - Redmi Note 10 Pro - without any permissions stalls at all using Total Commander 3.31, for example.)

Hi @Sheist! ,
All versions/editions of FX Explorer are considered a Trial edition when first installed... You can enable full features for a 7 - 14x day trial to which it reverts back to limited features. You only miss out on the bonus, networking/app management and few extra controls/filesystem features.... All the core Explorer features are still there...
This method was correct and accurate at the time of testing, which I believe I was on Android 11, as I don't think A12 was around at the time. Since upgraded to A12 afterwards it has still kept write access to the SD Card enabled after the hack.
I've not tried this method on A13 yet, as I am still on stock rom. However, each release of Android, from version 10 upwards keep tweaking SD Card usage, and restricts access to it more and more... So A13 could well have issues, don't know.
Personally, when I tried Total Commander back on A11, I couldn't get it to work at all (despite reading a guide somewhere) saying to use this. I tried all the various apps out there, one even suggested using the MiExplorer. No method worked at all, apart from that very specific release of FX Explorer, and when tried worked like a charm. As it always has done since Android 4.4x when Google first started messing around with SD Cards. I believe Android developers were asked to remove such features from their File Manager apps, hence why after 8.0.3.0 this feature disappeared.
There was a method briefly, using Googles own "Files" app, known as packagename "My Documents" or something like that... This feature only worked on Android 11, and had limited access when enabled. However as this is often a system app, and without root... Trying to disable, debloat, replace this app... this method also was fiddly and didn't work.... the only sucess that worked for me was what was mentioned above.
I tried practically everything, and was at the point of giving up and annoyed I wasted money on a 128GB SD card not to be used... until I stumbled on the above. Relieved it worked, and thought if it helps others in similar position, share the info... as I read pages and pages (forums/Googles own documentation) on how its disabled, how it no longer works, workarounds that didnt work... I believe it should still work for A11, and poss A12 roms (does via upgrade), however not personally tested on A13.
Cheers, Lister

The problem is I have other apps that need to write to the SD and at this point they started failing. I don't suspect A13, as CherishOS does not have this issue on RN10P, OR the SD card I am using on that RN10P phone is error-free. My card would not read in the crDroid recovery in my RN11 UNTIL I formatted it in Windows with NTFS. Even formatting in the phone in exFat gives an exFat error in the incorporated crDroid recovery! This is probably still some issue with my card or its formatting, as I don't see noise on this issue from other users. My external SD was working fine for my write/copy-to apps on A13 until I fixed the issue getting it to read in crDroid recovery, which oddly I don't even need anymore! (successfully installed TWRP to ramdisk now). I need to reformat back to exFat and see where I am. If good, then I will reply again.

I reformatted in the phone again (exFat) and all apps work fine again to/from the external SD card. I am on TWRP so I don't care about the installed crDroid recovery issue anymore. (A13, crDroid 9.3, TWRP 3.7.0_12-0)
