[Q] Unable to see storage card when running on Android

Hi all,
I am trying to get android to work on my old Tilt2 for my fiance so we can play games together. I've gone through all the steps by adding the correct files to the root of the storage card and running Haret. Every thing seems to work "fine" other than the fact that I can't see a storage card while in Android. I tried to partition my SD card to see if that would help but I am unable to determine the proper way to do that. Any help would be appreciated

Do you have some type of file manager installed on Android? I know that I could always see it, with the exception of the Android folder on my card.

I've said this 100x, not sure why it never shows up on people's searches...
But backup all the data on the card. Format the card (full format, FAT32) using the HP Tool. Restore all the data on the card after the format, or start over fresh doesn't really matter. Apps should now be able to see the card, etc.

I'm not concerned about apps seeing the storage card. I don't have a "My Files" app that will let me navigate the card. Do I need to download a file manager in order for it to work?

I fixed it.. I had to download a file management app I feel dumb now.

Which App?

Astro is pretty good, and is included in AndroidApps folder IIRC.

Amusingly, I use multiple file storage apps. Super Manager for making system files r/w, and file expert for the look and feel. I have astro too, on my other phone, but only really use it for enabling all file type downloads from the web.

Can't access SD Card on PC since RamExpander installation

Hi!
I recently installed the RamExtender application for my One V so it could run games more fluently.
However, right after installing it and creating a "ram-swapping" partition, my SD Card would not show up anymore in "My Computer" tab. I can only see my phone storage and the H: letter (usually the SD Card) is there but when I click on it, it says "Please Insert a disk into removable disk".
Please see the picture attached to the thread so you can see what's actually happening. The SD Card is not corrupted since my games still work and I can browse its files in ASTRO file manager... HTC Sync Manager won't sync either.
Any ideas how to fix it? I still want to put music and custom APKs in my SD Card!!
Thank you very much everyone

First of all, NEVER use these kinds of apps
if you're ROOTED, flash the Turbo Boost MOD
just delete the swap file u created from the SD card and you should be okay !

Thank you very much! Well I did uninstall the app and deleted the .swap file left behind by the app, but still the SD Card won't mount on Windows because it seems Ram Expander is not fully uninstalled
What other file/directory should I be looking for? How to be sure it's fully deleted?
Thanks again!

The best and final way is to make factory reset, wiping everything, including SD card....
Then just install everything from scratch and you'll have working hov...

Well I reinstalled the App in order to try it but there is no option to remove the swap file in it I'll try to contact the dev by Email and see what I can do...
*UPDATE* The dev says he's not avaible to provide me support. Contacting another user who used this app before.

Hope this will not be necessary. As a newbie in the Android ecosystem (I come from Windows Phone 7.8 lol), I had a real hard time rooting/unlocking my bootloader and installing the new kernel+rom...

U can do 1 thing.....
Use es file explorer and in the menu click on manager then choose SD card analyst.....
Once it stops scanning check 4 swap file if present delete it and reboot....
Hope it solves the issue

[Q] Invalid path of SD card

Im running Quantum V3, 4.4.1 KitKat on AT&T Samsung Galaxy S3. Last night I played around with phone, unmounted SD card cuz I needed to check my battery drainage. After I remounted it, ESfile explorer says that sdcard1 has "Invalid path". Even tho in settings > storage, it shows that there is sd card and how much space there's left on it...
I did a clean flash of the ROM before if that matters. I don't wanna reflash it and arrange all the apps all over again...
Also when I check the sd card through the app folders, aka in storage/sdcard1, it shows files and everything. What could be the issue that I cant get it to work?

Probably one of the bugs with the latest update by PwnCakes. Maybe you didn't unmount properly, or try formatting the sd card and plug it in again?

I have the same exact thing.

Sigh, at least I'm not alone xD
And I didn't try formatting, got 27 gig stuff on my SD card and unfortunately no space on HDD to copy all the stuff :/
Shame I ain't got enough posts to reply in PwnCakes thread...

I think it might actually be a bug within the rom itself OR ES file explorer. I had this bug since I think a few releases ago

I have the exact same problem. Under "device", i have two copies of extSDcard. I also get the "invalid path" when i tap on sdcard1. I guess i'll wait for a fix, as i don't want to uninstall ES File Explorer, and reinstall, just to lose everything.

I will post my workaround for ES when I get to my computer. It will basically circumvent the error to make it usable. Just keep and eye on this post, I'll edit it in.

Temporary ES File Explorer Workaround for SD Card and Ext SD Card
Sorry it took so long. Just got done finals and had to get the bus. Below is the settings that you guys can use to make it almost as if nothing was wrong with ES.
Set your directory settings for Home to the External SD Card
Change the default window settings to the following: Sdcard, Home, whatever else you want loaded AFTER these
This will make it so that the first loaded 'window' of ES is the device's internal memory. Then it will load the external SD card as the second 'window'. As long as you check it in the proper order, it will load just fine.

Followed directions, and i get LAN with a blank page, then i still have to tap on the top of the app, and go into the directory to find sd card, and ext sd card(which used to be sd card1. What would happen if i wiped data on ES File Explorer, deleted the app, and then reinstalled it? Thanks for any help.

Idk how you got LAN. Uncheck all of the windows then select them in the order I provided. Also make sure home directory is set to your external SD card at whatever path it is. Also can you provide a screenshot?

I'll be honest with you. I check play d store almost daily to see if there is anything new with ES. I don't know. It might be a problem with the selinux transition from 4.3 to 4.4. It could be a million things but I think its just some back end code for the file system. :/

@grunt0300 if you really want, I can take a look into the permission.xml. however, no way I am making the commits to my device at the moment. All I know (without looking up the exact wording) is that in permissions.xml is a line for read external storage and that line is set to media/mnt/sdcard instead of storage/sdcard1.

[Q] TItanium Backup SD card not writable after Lollipop Upgrade

I have the T-Mobile Galaxy Note 3. I was on stock and just took the OTA upgrade to Lollipop (N900TUVUFOB6). After doing this, I rooted the phone with CF Auto Root and installed TWRP 2.8.5.0. I have root access fine. I keep my apps backed up from Titanium Backup on my SD card. When I open up Titanium Backup it tells me the directory isn't writable. I am on the latest su binary / supersu and I have tried changing the mount namespace setting with no luck. Is there anything else I could try to fix it?

Did you install the SD card fix app?

I think there is an option on lollipop to authorize other apps to access directories that are not there own. That might be the problem.

I searched and found you need to change a setting in Preferences - Backup folder location. Near the top is Storage Provider. Click and change to Directory provider. Fixed it for me. Never knew that was a setting before!

Thanks so much! I had to pick the option DocumentProvider storage and then select the directory through there. Working fine now.

Sorry. Meant Document provider not Directory provider. ?

Has anyone found a reason why TiBu now thinks the entire directory of dalvik cache is unnecessary when you run the clean up option?

Changing that to DocumentProvider storage solved my problem too sjancura, thanks!

Hi,
I spoke too soon... I am still having problem with using external SD card with titanium backup.
I changed the storage provider to DocumentProvider but I cannot 'save' that selection as it's grayed out - please see the screenshot.
I have tried changing name of ex SD card. At first I used SDFix apps which were able to help with similar problem in KitKat but haven't fixed the issue now in lollipop.

I had the same problem (Running Lollipop and TB) and I got it fixed by using one of the KitKat fixes. The one I used was "SDFix" by "NextApp, Inc." in the google play store.

Hours of frustration brought to an end by that advice ... thanks mate ... you're a legend!

Hi,
I tried running SDFix, having run it in tbe past, prior to finding out this morsel of info on changing DP. However I still can't get it to save that location. Same greyed out directory like previous user posted.

Yeah I found that as well, changed it but could not "save" to that folder location (greyed out). Tried SDFix app, no change. Tried creating a new folder in TB, AND then using ESFile Explorer & neither would allow me to write to the extSD card. Rooted, stock Sprint Lollipop ROM.

I had that issue, worked it out. When you're browsing for a folder with the DocumentProvider select the root of the SD card, then it should close and return to the browser in Titanium Backup. Browse to the sub folder you want, you should be able to click the save button now.

Hi Ghosthree3,
Thanks so much for this. I'm going to give it a shot. My extSD card was used in the past on an earlier version of Android OS, whereby I could write to the extSD card just fine. Consequently there are prior backups on there. As such, I'm wondering if i should mount the phone, copy that folder off, delete that folder on the extSD card and then via TB create a "new" Titanium Backup folder and see if it then allows me to write. Note: I tried mounting the phone to my PC in an effort to create a folder on the extSD card and that method too, prevented me from creating a folder, hence my thought on getting what I have off of the device, and attempting writing a new folder per your directions. I wonder if my PC will allow me to erase that folder.....

Thank you!

Hi s j a n cu r a,
Thank you very much. Someone else posted that, but maybe i'm not selecting it properly. When I select Document Provider, I browse to "Open from SD card", scroll down to the "Titanium Backup" folder, hit "Select" the "Titanium Backups" that are there [at one time I had no issues writing to my EXT SD card], it then says, "Detect!" [External storage] and I select "Everywhere in External Storage". It finds 41 backups there, I select that "External Storage' radio button. That's where I seem to hit a wall. The "Use the current folder" appears to be greyed out. I'm left only with "Cancel". I think there is some deeper issue writing to ExtSD because with File Explorer I can't copy picture files from one folder to the other. That's what is giving me this feeling that something else is going on with write permission. Frustrating to say the least. My only recourse at this point is to use the internal SD, which does work.

Google lollipop external sdcard fix. There's an app in the play store.

Is there any way to get write permissions to SD card - xposed Fix EXTSD dont work

I seem to have been at this for hours now. I finally got Xposed framework on my Tab S and Note 4 and decided to try Marshmallow SD fix
https://forum.xda-developers.com/xposed/modules/xposed-marshmallow-sd-fix-write-t3403263/page29
and then EXT SD fix
https://forum.xda-developers.com/android/software/fix-extsd-fix-v1-0b-2016-01-18-t3296266
In each case going to Titanium backup it just doesn't work - I get the same old "Folder is not writable" message for anything on the SD card.
Since many people are having success - I'm assuming this is because of the Samsung version of Xposed framework ?
I don't know but nothing I do seems to work.
Any suggestions / advice - has anyone got this to work on their tab s or note 4?

If it's lollipop you need the sdcard fix. If it's mm you just need to allow write permissions to the app.

I'm not sure I understand that. Are you talking about extsd or marshmallow fix ? Also there are no permissions to set other than the ones shown. For Titanium those are all set to on. Ie. Storage.
Is there a specific 'write' permission elsewhere that I've missed?

Any app that wishes to write to the external storage should show a dialog requesting permission to the ext sd after that it will have full write access.
Any app that doesn't isn't mm compatible.
Which folder path are you trying to use?

The Titanium problem is fairly common. if all apps need to be was mm compatible then we wouldn't need a fix for the SD cards I would have thought.
But coming to Titanium itself I can select the old folder with is exsdcard/titaniumbackup but Titanium will tell me this has no write access but I can use it to read from and restore.
There is no location that Titanium will use or see on the extsdcard. What one has to do to is to copy the contents of your backup folder to the internal card then select that as the backup folder in Tba. Then you have elect to change the backup folder but choosing DocumentProvider storage. At this point you then have to create a folder - an existing folder is no good. Once created it will copy the contents of the internal folder to the extsdcard. Apart from the fact that this 'workaround' is much slower it is also inconvenient and any kind of change for whatever reason in the backup folder means that you can't just switch to the old one you have to go through the whole creation process.
As far as I am concerned this is why I wanted an SD card fix but I also understand to some point your view and it does make some sense. However it is confusing. When this nightmare started with Kitkat I understood that apps were allowed their own folder but couldn't affect or write to other folders. Also they were media folders only. This as I remember also affected file managers which then couldn't do their intended job.
With MM and without any fix Solid explorer can and does have full access to the sd card and can write in any folder from what I can see. Other apps seem to possibly access with documentprovider permissions - I'm not sure but many appear to have no problems but the pop up is very much like the documentprovider - choose a folder. So I am confused why Titanium has these problems and can understand a point of view that they haven't adapted as they should have perhaps but then I find it hard to believe that they wouldn't have done what they can with the features /tools they have for one of the most popular backup programs..
Either way, at the end of the day I was really hoping I could have got a fix which worked much like sdcard fix on Kitkat which stopped the nonsense and Google's insistence that they know best how we can and should use our SD cards.
And indeed for many people Marshmallow fix and or EXTSD appear to work for a lot of people in the way I was hoping - hence the creation of this thread because
1) it certainly doesn't for both my Samsung devices and
2) Many people with Samsungs (and some other devices) appear to be having the same difficulty.
I don't understand what has been done on MM to make it so difficult to overcome the problem but obviously it appears Google is just plain bloody minded and trying to make it more foolproof.

The fix for KitKat and lollipop isn't needed for MM because Google did in fact listen to people griping about the ext card restrictions.
MM will give full access to properly coded apps.
I have many different devices running MM and all gave write access to the ext sdcard including TB, which I use regularly.
However that doesn't mean to say I haven't had the issue you speak of. I may have even had it with TB.
The folder path I use in this case is mnt/media_rw/
This path is almost always accessible by apps and is the path I'm using right now for TB.
If that doesn't work try disabling 'mount namespace separation' in SuperSU settings then reboot also make sure your TB is up to date.

I'm guessing then that the so called Marshmallow fix via xposed is to get older apps which may not be updated to work

However that doesn't mean to say I haven't had the issue you speak of. I may have even had it with TB.
The folder path I use in this case is mnt/media_rw/
This path is almost always accessible by apps and is the path I'm using right now for TB.

Ok so now the plot thickens and I've no idea what is going on here. Tba says when I navigate to this folder [and I'm assuming that the choice when asked is "filesystem storage" and not "Filesystem storage - Media" (which only offers internal memory anyway)]
"This folder cannot be accessed"
and that is before getting to the external sd card which would be the number (F91E-D472) in my case. ie. mnt/media-rw
Needless to say - Solid explorer can see this and navigate to the sd card no problem.
This happens on both Note 4 and TAB s and I'm really curious now because something on my systems are different.

If that doesn't work try disabling 'mount namespace separation' in SuperSU settings then reboot also make sure your TB is up to date.

Sure, namespace is unchecked - did that on both devices some time ago, and Tba is up to date.
Pretty damn confused now

Ok understood.
I'm guessing then that the so called Marshmallow fix via xposed is to get older apps which may not be updated to work

Have you tried placing the TB folder on your ext sdcard then used the detect button (whole device) in preferences to detect the folder and then select it under mnt/media_rw?

This was the method I used as soon as I updated to MM and didn't notice the "this folder is not writable" message.
However, the option to choose mnt/media_rw isn't available. If I use Detect > whole device I'll be offered :
/storage/F91E-D472/Titaniumbackup
perhaps I'd see the other option under normal circumstances but Tba is not able to access that path so wouldn't find it in a search ... I guess

Aha! could this be the problem?

What is your sd card formatted as - mine is FAT32 so perhaps I need to go exfat?
..but then such links show that I'm certainly not alone - this one actually confirms that tb has this write problems and leads to the Documentprovider solution:

ExFAT. Anything above 4gb should be ExFAT.

curiously I set permissions to 777 for the mnt/media_rw and titanium can go there but any further (even though I've done the same for the sdcard folder - nada!
and sadly after converting to exfat - mnt/media_rw .... "this folder cannot be accessed"
Not sure what else I can do.
