General :: Using EXT4 Partition Makes Folder Permissions Unable To R / W

May 6, 2012

Basically, it's a permissions problem. I've tried using Permissions fix on CWM but with no luck. As FAT doesn't have a permissions subsystem, seems like there is no problem with it, but as EXT4 has it, everytime the phone creates a new file/folder, it cannot read its own file.

Although I can connect and see the files on the computer, they're marked with a padlock. It means I don't have permission to access it.

I can regain access to the file and the phone can read it back again, but it's a pain in the place if everytime the phone creates a file, I have to put it back to the computer and redo the permissions sets. It can't even view it's own files. I've already tried to set the SD card root permission to myself, and with everyone capable of read/write access. But unfortunately, newly created folders aren't affected by this.

As far as it looks like, it creates a 'user' for every app that makes the file.

For example, the folders on that picture were created by the camera software, so the user of both is "10041 - user #10041". It has R/W access, but nobody else has access to even see what's inside.

I really enjoyed the transfer speeds with EXT4 (I'm on Ubuntu 12.04), even inside the phone and outside, using USB cable and apps feels snappier. I don't want to go back to FAT32..

I'm using a Motorola Atrix 4G and Morrisoft CM7 latest buid (Custom ROM).

Just to clear things up: Device CAN read and write files under EXT4, but it trips on its own tail by settings permissions badly.

General :: Changing Ext4 Partition To Swap Without Having To Format Entire SDCard?

Apr 27, 2013

One of devs from my device had told us that he'll move system and data images from sdcard to SD ext, but actually he left before doing this so now I'm stuck with useless 5gb ext4 partition on my scard. I'd format it and then change partitions if my sdcard wouldn't be filled with over 20GB of various files. Is it possible to change the size of the second partition to about 500 MB and turn it from ext4 to swap without formatting entire sdcard?

General :: Internal SD Partition Or Folder?

Sep 12, 2012

but is the internal SD in ICS a partition or a directory on the system that pretends to be an SD card?

If it's a partition then I don't really see the benefit over an external SD - except where there is no SD slot. Obviously if it's a directory then it would grow as required...

General :: Shutdown Makes Phone Unable To Boot Without PC

Jan 21, 2013

After unlocking my phone's bootloader and flashing the kernel:

When I power off the phone, it gets into a state where I cannot control it by itself (black screen, no charging light if connected to a power source, does not react in any way to any key).

However, I am able to access it via adb over USB. Using adb, I can put it into some other state (reboot, reboot bootloader, etc) and again gain control over it (also through its own keys). When I select the "power off" function of the bootloader, it enters this state again.

I can even reboot the phone (also into recovery/bootloader/fastboot) from any state

So I can use the phone, but I can't power it on by itself, which isn't a good situation when I don't have a computer around.

device: HTC One S
ROM: CyanogenMod 10 (device is officially supported by CM10; I used the version I found in the Wiki.)
kernel: The one included in CM10 (had to be flashed manually via fastboot because of restrictions by the device; I flashed the kernel before flashing the ROM)

General :: TWRP Unable To Locate Android Secure Partition

Nov 16, 2012

I've had this issue with Nexus 7 rooted stock ROM 4.1.2 and 4.2 using TWRP 2.3.2.1.

Earlier I had gotten a TWRP version to save to a USB-OTG but then I had some problems with root and I re-rooted the device. Then I got error message trying to use TWRP. I upgraded to 4.2 and problem persisted.

Running stock ROM 4.2 on rooted Nexus 7.

Backup Complete
Failed
Backup Folder /data/media/0/TWRP/BACKUPS/hash and date
E:Unable to locate android secure partition

Using Ghost Commander, I go to /data but the folder does not open. I can go to /sdcard/TWRP/BACKUPS/hash/hash/date and that folder does open, but it is empty.

General :: Mount Arbitrary Phone Partition On PC / Change Partition Names?

Oct 8, 2013

I am running rooted stock Android 2.3 on LG E405 (no working 4.x ROMs exist for the device)

I have two questions:

1) What is the shell command to manually make android allow the PC to mount androids' (internal) partition as USB-drive? (I cannot think of right keywords to google this one up - )

2) How does android determine which partition is which (i.e. which one to remount for the PC when connecting in "USB storage" mode), beside vold.fstab and init.rc? On android 2.3 that info is not in "framework-res.apk", so where is it? In the partition table itself?

I had switched data partition with internal sdcard partition.

Here's how: Phone had a very small "/data" partition on /dev/block/mmcblk0p21 and large internal "/sdcard" partition on mmcblk0p20

So I reformatted mmcblk0p20 (ex-sdcard partition) into EXT4 and mmcblk0p21 (ex-data partition) into FAT32

Then I changed init.rc to mount mmcblk0p20 as /data type EXT4 and mmcblk0p21 as /sdcard type VFAT (mounting /sdcard was commented out in stock init.rc for some reason). This required modifying my boot image.

I have also set correct partition number in vold.fstab:

[#]dev_mount sdcard /mnt/sdcard auto /devices/platform/msm_sdcc.3/mmc_host[/#]

So basicly I now have a large /data partition and small internal /sdcard. I'm able install up to a gigabyte of APKs and it works fine.

However, when I connect to my PC via USB into "USB Storage" mode, the phone seems to still try to unmount what was previously sdcard partition (/dev/block/mmcblk0p20), instead of what is NOW an sdcard partition (/dev/block/mmcblk0p21) I can still send files to the phone via wi-fi and ADB, but the ability to mount it directly would be nice.

If I accidentally select "erase internal sdcard" from storage menu, that will also most likely erase what is now my /data partition, softbricking the phone. The "factory reset" option will probably only corrupt the sdcard.

General :: SD 2nd Partition Doesn't Work - MiniTool Partition Wizard?

Oct 19, 2012

I'm have been trying to create a second partition on my sd card using miniTool Partition Wizard.But in the end I never get a 2nd partition but just a smaller first one.My approach is as follows:

insert empty SD card (FAT32, 4GB)
open miniTool Partition Wizard
right click on SD card - "Move/Resize"
choose 1gb for unallocated space after - click ok
right click on 2nd partition and choose "create"
create 2nd partition with FAT32/Ext2/Ext3 (tried all options already) and "primary" and Cluster 4KB - click ok
Apply

Afterwards my SD card is still shown as one partition, but this has just 1gb less capacity then before.Neither the Wizard nor the phone detects the 2nd partition then.

General :: Partition Layout - Exact Meaning Of Value In CWM - Partition SDCARD

Aug 26, 2012

I can't figure what is exactly meaning the Partition Sdcard values in CWM.

I have an i9000, with 8Gb of flash. Some are system reserved. Available is around 6Gb.

When i run CWM, i can partition my sdcard, but i don't see what means the possible values (for 256 to 4096).

This is obviously not ruling the space left on /sdcard mountpoint (i partition to 2048, i still have nearly 6Gb available)... So what exactly means partition sdcard from CWM ??

i can't find an answer, and i dislike, when flashing rom, following commands i don't really master (generally a partition SD 2048 / SWAP 256 or SWAP 0).

General :: How To Delete Partition 4 And Extend Partition 3

Jan 14, 2013

I have bought a cheap chinese phone that had a 4g rom. 512mb is mapped to data as p3 and p4 is mapped to internal storage which is 2g.

I have managed to work out how to delete partition4 and extend partition3 as they follow on from each other.
However how do I remove all links to it in the system as it still tries to mount it on boot even though it isn't there.

I have removed the line from vold.fstab and that just crashed the external and internal sdcards and the storage section inside the system settings.

General :: App Update Permissions - Any Way To Restrict Permissions?

Jul 23, 2012

The permissions say that you must agree to allow them to delete files from your storage including your SD card; must agree to allow them to extract any information from your phone, etc. In other words they can do any thing they want with your phone and the data in it.

Is there any way to not grant these permissions and still get updates?

General :: Unable To Customize Folder Icons On DROID Phone Connected To PC

Nov 22, 2011

I can successfully customize folder icons on a removable Flash Disk using Desktop.ini file and a separate icon file. But I am unable to do the same thing on folders on the connected phone device that, for all I know, is similar to a removable device. The phone is a Samsung Droid Charge. When I copy the Desktop.ini and the folder containing the icon file from the pc to the memory card, nothing happens. The icons for the folders still have the same default appearance. Don't know how many people care to have custom icons but it is a nice thing to have when you are always trying to identify a few folders from many.

Android : Unable To Browse /sdcard - Permissions Denied

Feb 28, 2010

On both the emulator and my actual phone (tattoo) I seem unable to browse the SD card - when I run ddms and use the File Explorer, I can browse /data or /system fine, but /sdcard refuses to open, and its permissions appear to be "d---------" (which of course might be the problem).

Similarly when I use ddms's "Put file on device" it fails:

29:43 E/ddms: transfer error: Permission denied Failed to push about.html on SH9CELG00306: Permission denied

The above is for my actual phone but I get a similar error on the emulator (which does have an /sdcard).
