General :: How To Read / Write Ext3 File System Image In Ubuntu

Feb 18, 2012

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.

General :: Huawei U8800 Ideos X5 V2.3.5 - Not Able To Mount System As Read / Write Properly

Nov 13, 2012

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.

General :: System File Read Only?

May 31, 2013

I am trying to revive white Pandigital using ADB commands to push files on the system's folder of the device then flashing them.

The computer sees the device, adb has root access, yet when trying to push files is gives me an error indication that the system/data/midc is a read only. tried adb remount over and over with no lick. Is there any other way to get to write on the system folder?

Android :: Write / Read Access To SD Card In Manifest File

Mar 1, 2010

Is there a right associated with write/read access to the sd card that needs to be set in the manifest.xml file? I'm currently trying to write to the sd card using a standard FileOutputStream here:

FileOutputStream out = new FileOutputStream("/ sdcard/images/"+imageName);
bmp.compress(Bitmap.CompressFormat.JPEG, 90, out);

But it doesn't seem to be working. It just says the location isn't found, which can happen if there are no permissions to read/write to the location.

General :: Can Mount Android File System Image?

Dec 10, 2013

So after a failed attempt to upgrade from CyanogenMod 10.1.3 to 10.2, I was unable to access /data or /sdcard because both systems were encrypted. I ended up having to factory reset my phone because it refused to co-operate or let me access my files. However, before I did that, I was able to run

Code:
adb shell "dd if=/dev/block/mmcblk0p2" > data.img
and

Code:
adb shell "dd if=/dev/block/mmcblk0p3" > sdcard.img

Which appears to have copied the raw partition images from the phone (at least, they're the right sizes).

According to my reading, Android (and, I'm inferring, CyanogenMod) encrypts filesystems using dm-crypt, with a AES-CBC ESSIV:SHA256 cipher, with the key being derived from the password using PBKDF2. Knowing the precious little I do about encrypted file systems, my guess is that if I configure the image in cryptsetup to create a drive mapping, I can mount the mapped drive and recover the data from the images.

According to /fstab.herring on my ahem, fresh, install of Android, the /data partition is in ext4 format whereas the /sdcard partition is vFAT. So, once I've gotten through the encryption on the partition images, they should mount normally, right?

I know that dm-crypt accepts plain, LUKS, LoopAES and TrueCrypt device formats. I'm inferring from the PBKDF2 extension that Android goes the LUKS route for encrypting. Is this conclusion correct?

Whether it's possible to decrypt a dumped android image? I'm really hoping that the cypher information is stored on the file system and not on some key file that I nuked in the factory reset. If it can, in theory, be decrypted, am I using the right tools to approach the matter? If so, I'll continue fiddling with cryptsetup and mount, but no sense in wasting time if it's an impossible task.

Android :: Write Contents Of Custom View To Large Image File On SD Card

Mar 12, 2010

I have a class that extends View. I override the onDraw method and allow the user to draw on the screen. I am at the point where I want to save this view as an image. I Can use buildDrawingCache and getDrawingCache to create a bitmap that I can write to the SD card. However, the image is not good quality at a large size, it has jagged edges. Since I have a View and I use Paths I can transform all by drawing to a bigger size. I just don't know how to make the Canvas bigger so when I call getDrawingCache it doesn't crop all the paths I am just transformed. What is happening is I transform all my paths but when I write the Bitmap to file I am only getting the "viewport" of the actual screen size. I want something much bigger.

General :: Can't Read / Write SD Card

Oct 23, 2012

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?

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.
