General :: Use Vold To Mount Unlocked Dm-crypt Volume?
May 5, 2013
I'm trying to get my SD card encrypted and I've been able to successfully mount the luks volume, but due to the way that Jelly Bean 4.2 (Cyanogenmod 10.1) presents folders to user apps, only my terminal emulator can list the files.
In my troubleshooting, I've found that a standard mounted SD card is first mounted to /mnt/fuse/sdcard, and then an abstraction layer through a fuse driver mounts it to /storage/sdcard1 in order to set file permissions that all apps can access.
Right now, I'm trying to trick my vold.fstab into mounting the dm-5 device that appears in /sys/devices /virtual /block when the dm-crypt volume is opened. Unfortunately, since the original sys folder for the sd card is in /devices/platform/msm_sdcc.2/mmc_host/mmc1 format, I'm not sure where to direct vold.fstab to check the presence of the dm-0.
I'm aware that as asec apps are installed the dm-5 can change to something higher (dm-6+), but I'll cross that bridge once I get part one working.

I am porting android to my own device now. I checkout the latest source code from android.git.kernel.org. I have successfully compilated filesystem images and burn those images to my devices. But i couldn't automatically mount my sdcard when android startup. The / sdcard directory is empty when i used 'ls /sdcard' command. I have copied the vold.conf file from development/data/etc direcotry to my device(/system/etc), but it's invalidated. When i read the source code(vold), i found the vold daemon relate to switch driver, device mapper driver and android gadget driver. Are there some document or information about how to configurate android kernel to support vold new volume management and wirte right vold.conf configuration file?

I'm working on a CM port and currently facing issues with vold. For some weird reason, vold isn't mounting storage devices as it should. Here is my current vold.fstab file:
Code:
dev_mount flash /storage/sdcard0 auto /devices/platform/mtd/mtd8/media nonremovable
dev_mount sdcard /storage/sdcard1 auto /devices/platform/AMLOGIC_CARD/card_host/memorycard0.
Using adb I can confirm that everything is mounted correctly and also I can browse the files. Using applications (even MediaScanner) fails with permission errors. This is how I'm creating the storage folders, for user/permissions reference:
Code:
# Create mountpoints
mkdir /mnt 0775 root system
export EXTERNAL_STORAGE /storage/sdcard0
export SECONDARY_STORAGE /storage/sdcard1
mkdir /storage 0550 system sdcard_r
mkdir /storage/sdcard0 0000 system system
mkdir /storage/sdcard1 0000 system system
[code]....
I have also noticed that the system reports different owner/group/permissions through adb and Terminal Emulator. Here are the outputs:
Code:
root@android:/ # ls -la /storage/
d---rwxr-x system sdcard_rw 1970-01-01 02:00 sdcard0
d---rwxr-x system sdcard_rw 1970-01-01 02:00 sdcard1
d--------- system system 2013-09-05 02:29 usbdisk0
[code]....
I'm suspecting storage_list.xml, but I checked mine and seems correct. Also, it doesn't define permissions, so I excluded that.How can I further debug this? Logcat doesn't show anything useful, everything seems fine with vold.

When the (HTC Desire) phone is powered up it is unable to mount the SD card, and I am unable to have it mounted from the "Settings > SD card & Storage" menu. Having said that, the micro SD card can be accessed from a computer (when plugged in directly to the computer, i.e. no issue with the card), and moreover, when I am in the recovery mode, I can have it mounted and browse it. By the way, the card could be accessed from the phone until I downgraded the O/S, and managed to have it rooted.
When the phone is running normally, and connected to the USB port of a laptop, the laptop does recognize a device connected (can even do ADB), but I believe because the SD card is not mounted, the phone does not offer the option to make the card appear as a disk drive for computer access.
I am running the original (RUU, Telstra) Android 2.2 (2.26.841.2) on a HTC desire, after I had it "S-OFF'ed". After reloading the original 2.2, I had it rooted.
The micro SD card is a 2GB one, with approx 1.5GB formatted as FAT16 (contains typical file and photos), and 0.5 GB as EXT3 (contains nothing at the moment).
HBoot: 6.93.1002
S-Off ( Revolutionary)
Recovery mode: ClockworkMod v5.0.2.0 (I manually loaded it)
I have searched online for solutions, and have not been able to have it fixed. Others seem to have different issues to that of mine. Usually, they cannot mount the SD-card at all (not even from recovery), or their SD card just needed to be reformatted. I think I have indicated that these do not appear to be relevant to my issue at all. I have also tried "Fastboot oem enableqxdm 0", and it made no difference.

Recently purchased the Virgin Mobile Supreme (Sprint Vital, ZTE N9810). The one thing that is bothering me is that there is only one volume setting for the combined ringtone and notifications. I would like to set these volumes separately.
I tried one volume control tool, but even though it had 'separate' controls changing ringtone changed notification and vice versa.

So I'm pretty new to rooting. On some themes or roms they require me to Mount System and Mount Data. I have clockwork recovery installed and when I select the option Mount System, it just acts like i didn't select anything. Is there something I'm doing wrong?

I want to give a hard reset to LG Optimus Sol which was initially blocked Vodafone and I unlocked it at a service to work with all networks. If I hard reset the phone will become locked again in Vodafone? I want to do this because the phone does not connect in data storage mode and the bluetooth does not work.
You can tell me if I hard reset will install all the default programs on the phone they had originally? Or is another possibility to reinstall the factory software without being locked again in vodafone? I searched the forums but some said that the phone will be locked again and others say that will remain unlocked.

Somehow I managed to get my Samsung Google Nexus S 4g phone unlocked and rooted today. In the process I installed the TWRP recovery as per the particular instructions I had. I would like to install something called the Avatar ROM but they say I need the ClockworkMod recovery. Should that make a difference? if yes, where can I find it and how do I install it instead of the TWRP on the phone now?

I've got an HTC One & I've already unlocked the bootloader but had to give the computer I was using up before I could install recovery or SU. SO, is there any possible way to get a recovery onto my One without a computer? Then I can just flash a rooted ROM. I am also still S-ON.

I have been trying to follow the tutorial to take my Nexus 7 (2013) from it's just unboxed state to dual booting Android and Ubuntu Touch. I succeeded in unlocking the tablet. I am using Ubuntu 13.10 on my laptop and installed the whole Android SDK and everything (even though I already had Eclipse installed for learning Java). I've reached two sticking points.
First, the part where I'm told to copy the three files (the MultiROM zip, the kernel zip, and recovery image) to the root directory of the tablet: it's not clear how to do that. The files wouldn't copy except to the internal storage folder. Or is that the root directory?
Second, I am unable to boot to recovery.
Code:
adb reboot recovery
command only brings up the android on his back with the red triangle containing an exclamation mark. That screen lasts a minute or so and then the device reboots normally on its own. I have tried several power and volume button combinations to get a different result at this point, but to no avail.

I'm using the Oxygen ROM on an HTC Desire HD. When I leave my phone alone for a while and come back to unlock it, performance is often slow for 20 seconds to the point where swiping between launcher screens is sluggish. After this time it goes right back up to normal speeds.
Is this possibly related to the CPU settings in my ROM? The settings are available governors - interactive, min CPU - 245MHz, max CPU 1024 MHz. My guess is that when the phone's idle it goes down to 245MHz and takes a while to get back up to regular speeds. Am I looking in the right place and how much would increasing min CPU frequency affect my battery life?

I've followed instructions on htcdev.com to unlock my Sensation XL and everything worked fine.
Afterwards I tried to install the ICS custom ROM which I downloaded from this site.
The installation seemed to be successful, but when my phone wanted to reboot, it got stuck on the "HTC" logo.
I also tried another custom ROM and had the same problem.

I am planning on getting the Samsung Galaxy Note 3 soon but I am going to buy it unlocked. Is it possible to root an unlocked phone. I have not seen any guides on Youtube or online yet that show guides on rooting a certain unlocked phone. I want to root it as soon as it is possible to root it safely. I am going to buy it unlocked but I am not going to get a plan from T-Mobile from it until January. My main question is: Is it possible to root a smartphone that does not have a sim card in it and is bought unlocked and if there is what guide do I use(like do I use the guide for how to root the galaxy note 3 tmobile edition or att edition or verizon edition.)
