General :: 64gb Micro SD Write Protected / Read-Only After Flashing ROM
Feb 10, 2014
I have a M919V Galaxy S4 which is compatible with both the i9505 roms and M919 (TMO) roms. I was on a i9505 TW rom and I decided to download a rom from the TMO section. When moving from a i9505 rom to a M919 rom, I had to flash the recovery corresponding to the model. So I downloaded the T-Mobile version of Philz Recovery, but I got a status 7 error. Then I downloaded the md5 version and flashed it via odin 3.07. It was successful. After flashing the recovery, I flashed Beanstalk rom for the t-mobile variant. Everything went fine until I tried to make a android of my current setup for Beanstalk. I kept getting errors. When I plug my phone in (with my sd card), and try to add or delete something, it say "remove write protection and try again". So I tried connecting my sd card to my sd card adapter. When I delete files from my adapter, the error message doesn't show up. BUT... after disconnecting and reconnecting it again, the files are back where they were. I tried reformatting it but nothing happens. It seems like my sd card is only read as write protected when connected to my phone but it has no idea which state it's in when connected to the sd card adapter.

I have been having this problem since i updated to froyo JP2 package my external micro SD card when mounted to computer and i try to copy over the files it says it is write protected but there is no key to slide, as everybody knows micro sd cards donot have that feature by design. this is the best part when the same card no changes i put in to a cardreader hooked up to my laptop works perfectly fine. it was working fine before i flashed the JP2 firmware. what am i doing wrong i even formated the card in the phone itself but still no luck. My hunch is this when i flashed with new firmware i never took out the sd card and the sim card is that any reason, i know i can just flash it again but i already arranged everything nice on my galaxy so was wondering if it is then i will go ahead.

"You know we can easily read password protected .ppt files on our computers by clicking onto READ ONLY..This allows us to check these files even if we don't know the password. On Android,some softwares such as Office Suite Pro etc. Can open password protected files but they demand password for it. Is there any possibility or way that I can view these password protected .ppt on my android without entering password as Read Only as I do on my computer."

I did a backup using Titanium Backup and Go Backup and after wiping my Motorola Defy, tried to restore apps, contacts etc. The problems I encountered were:
1) Go Backup can't recognize backup directory on SD card for some reason.
2) Can't move apps to SD. An error occurs: "Move Application: Failed to move application. There is not enough storage left." Needless to say, I have more than enough storage.
This is was I encountered by far, although I believe these are just a small part of the symptoms for a single problem.
Maybe its because there are no permissions, or moving apps is impossible because of an existing app files on the SD card.
What is the actual cause for this? Or is there a tool to fix the permissions on the Defy?

Running 4.2.1 Supernexus on an i9100, I had a 32GB Micro SD card in the phone and when I had it connected to my computer I formatted it, except I foolishly set the format to NTFS. Now android won't read it (doesn't show up in storage) nor will it mount it when connected via USB so I can't put it back to FAT32/exFAT
Installed Paragon's NTFS mounting tool which mounts the drive but it's still not showing up in storage or being mounted via USB.How can I format it back to FAT so it will be read by windows and/or android? I'm surprised there is no SD Card formatting apps out there.

I developed a cramfs rom for the np7 after user dochoppy found root for the nextbook premium 7 tablet, but he then converted to ext3 which because its packed with features will be more popular. So I am trying to edit his ext3 rom in Ubuntu 11.10 and here is what I do:
1. Copy and paste system.img to desktop
2. Create a folder called system on desktop
3. In command prompt:
cd ~/Desktop
Sudo mount -t ext3 -o loop system.img system
(Asks for pw)
4. Doc said something about only being able to edit as root, so after some Googling I find out how to create a program that grants root.
5. (Open "run as" program) then I type "nautilus /home"
(Asks for pw)
6. Navigate to mounted system and I have read/write privileges (but only in this window)
7. View the system mount properties, and it says I have 14.2 mb free space on device
8. Delete files throughout the system folder to make room (but when I refresh properties, free space increase doesn't show)
9. Try to add my own files after deleting some others, ans rather than using the increased space, it just fills the fourteen megs before telling me "device is out of memory "
why is the system not physically making the proper system increase and decreases.

I'm having a problem with ES file explorer. After several days I managed to root my HUawei U8800 Ideos X5 (Android 2.3.5) and obviously one of the next steps is installing CWMR. Unfortunately I'm failing here too. I tried to copy the recovery.img to the .cust_backup/image, but it keeps to say copy failed. Root access was given and I checked all four boxes in root settings. Someone in a german forum told me to update the binarys in SU, which failed too (it says sth like copy su to /system -> failed!). I'm not even sure ES FE would work if the binarys would be current.
I already tried the app Mount /system (rw / ro). It didn't work with this too.

Is it possible to write data directly from my phone to my micro SD card? I got my Captivate a couple days ago, and I've been trying to research as much as I can about it, but I can't find this info. I know I can do it with a computer, but I don't have one. I want to put music and apps I download on the micro SD if possible.

I live in the middle east and i bought a galaxy tab p7500 3g 64gb from Amazon..as you know they come without arabic language so i need to flash the arabic firmware (ROM) and i already have all the files ready for flashing..but my question is where can i find a pit file that is compatible with the 64gb unit..because from my experience flashing the wrong pit file it will reparation the sdcard incorrectly.
i.e. once i used a 16gb pit file on my 32gb galaxy s2 my internal storge changed from 32gb to16gb and the problem didn't get solved untill.i flashed 32gb pit file into the odin..One last thing if i installed the arabic rom without using the pit file and removed the tick from repartion in odin will this method work.

I'll open with, I googled this thing like crazy, searched anddev and a few other boards (including this one) and can't quite find what I'm looking for.
The predicament : all CSV examples are in reference to contacts, and the file read/write posts (the ones that I need) make the assumption that I am not a beginner and most don't even post any code leaving me nothing to learn on.
The hopeful solution : a link to a solid example of simply how to write to a CSV with my own custom fields and values, and how to read a CSV and load said values.

I have the HTC incredible, and I would like for it to be able to read memory cards other than the micro sd. Specifically, I am interested in using Sony Pro Duos and transferring pictures from the pro duo card to my device. Assuming I acquired the proper usb cables and then hooked a card reader up to the device, would this work?

From what I was told, the Inc supports 32gb microsd card. So I ordered a Sandisk one...class 4. I got it and tested it out. It seems like it can transfer/read small files....but anything big it wouldn't read properly. It's funny cuz a movie file would transfer and play...but if I delete it and transfer the same exact file over, it wouldn't play. Or if I transfer music, some files play and some wouldnt. And some even would merge into one file. Like one song would play and then all sudden another song would POP up like what a DJ does when they mix songs together.
I know I might have a defected one but this is a legit Sandisk card. So what else could be the problem? Should I transfer the file one or slower so the card can read it....is there a way or procedure to using a 32gb MicroSd card? Lol. I mean I have a 16gb right now and it reads and transfers fine. With the 16gb I can literally drag a folder of 10 movies and it would be fine.

My new HTC desire is unable to read or write to my 8GB SD card which was previously inside my HTC HD touch.
Why is this? I've swapped the SD cards around - i.e. the 4 GB SD card which it came shipped with is now inside my HTC HD touch It doesnt have a problem reading or writingto the 4 GB SD card that it came shipped with. I would prefer not to have to format the card

I cannot read and write extended characters (French accented characters, for example) to a text file using the standard InputStreamReader methods shown in the Android API examples. When I read back the file using: the string read is truncated at the extended characters instead of at the end-of-line. The second half of the string then comes on the next line. I'm assuming that I need to persist my data as UTF-8 but I cannot find any examples of that, and I'm new to Java. Can anyone provide me with an example or a link to relevant documentation? Code...

I have an application that can read and write txt files to the phones sdcard. By using this code for reading files:
@Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); mFileNameOpen = files.get(position);
String st = null; mVector.clear();
notepad.mNewEmpty = false; try { File f = new File(Environment.getExternalStorageDirectory()+"/ notepad/"+mFileNameOpen); FileInputStream fileIS = new FileInputStream(f);
BufferedReader in = new BufferedReader(new InputStreamReader(fileIS));
do { st = in.readLine();
mVector.add(st);
}while(st!=null); in.close(); ...
} catch (FileNotFoundException e) { e.printStackTrace();
} catch (IOException e) e.printStackTrace();
and this to write them:
try { File root = Environment.getExternalStorageDirectory();
File fileCheck = new File(root, "/notepad/" + fileNameSave + saveExtension);
boolean exists = fileCheck.exists();
if (!exists) { if (root.canWrite()) { File textFile = new File(root, "/notepad/" + fileNameSave + saveExtension);
FileWriter textWriter = new FileWriter(textFile);
BufferedWriter out = new BufferedWriter(textWriter);
out.write(SAVEAS); out.close(); written = true;
} else { written = false; else { written = true; showMaybe = 1; showDialog(DIALOG_SAVE_EXISTS);
catch (IOException e) {Log.v(getString(R.string.app_name), e.getMessage());
This has been working fine on my Tattoo and all the emulators I've tried this on. But it does not seem to be working on moto droid. Is there something different to consider with moto droid? Or have I missed something in the manifest maybe?

I want to know how to get SMS Delivery Report setting which is stored in the /data/data/com.android.mms com.android.mms_preferences.xml. I wrote a application to read it with the following code:
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); boolean requestDeliveryReport = prefs.getBoolean( "pref_key_sms_delivery_reports", true);
Seems it does not work, it always returns the default value which is "true". Does anybody know how to read/write the SMS Delivery Report setting.
