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 :: Huawei 8650 - Link2SD Won't Mount SD Card Partition?

Jun 9, 2014

I have a Huawei 8650. I had updated my phone to Android 4.4.2 and i still have root access and all that good stuff but when i try to give root access to something like Link2SD or Root Explorer it will only give it partial permissions. Link2SD wont mount my sd card partition and root explorer wont gain root access at all. Both apps have the error "char* ttyname(int)(3) is not implemented on Android char* ttyname(int)(3) is not implemented on Android mount: Invalid argument". Idk what this is or how to fix it. how to fix it so i can use my sd card partition and fix my wifi.

General :: Correct Format / Partition Layout For USB To Auto Mount?

Apr 25, 2014

I've got a 3TB external drive drive hooked up to my Ouya running CM11 (Android 4.4)

I run Nzbget and Transmission in optware, and use CM primarily as a vehicle for XBMC so I need the space.

I had it in 2 ext4 partitions which needed a init script to mount under the stock OS.

I was hopping to get it working in a less hacky manner under CM.

I tried with the two parts, and no go so i redid it with one big partition with root as the UID and sdcard_rw as the GID.

Still no dice. I can access it in File Manager with elevated permissions, but no go in XBMC or other apps.

Also tried one big exFAT partioning with no luck.

I plugged in an 8g ntfs drive I had and it automounted it no problem.

What is the right way to configure the drive? We're a Linux household so sticking with ext2/3/4 would be ideal. NTFS I would like to avoid.

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 :: Disable Moving Of System Dalvik Cache To /cache?

Aug 16, 2012

In cm roms, dalvik cache of system apps are generated in /cache but those data/apps are generated in /data. Is there any way to disable this behaviour? Cache partition in our phones is too small. In AOSP and AOKP and stock roms, dalvik cache is always generated in /data no matter whether its a system app. any way to achieve this in cm roms?

General :: Phone Not Mount SD Card But Mount In Recovery Mode

Apr 1, 2013

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.

Android :: Android - Image Cache Stategy And Memory Cache Size

Jun 21, 2010

I'm implementing an image cache system for caching downloaded image.

My strategy is based upon two-level cache:
Memory-level and disk-level.

My class is very similar to the class used in the droidfu project

My downloaded images are put into an hashmap and the Bitmap objet is wrapped inside a SoftRererence object.

Also every image is saved permanently to the disk.
If a requested image is not found into the Hashmap<String,SoftReference<Bitmap>> it will be searched on the disk, readed, and then pushed back into the hashmap. Otherwise the image will be downloaded from the network.

Since I store the images into the phisical device momery, I have added a check for preserve the device space and stay under a 1M of occupied space:

CODE:.................

This method is called sometime afte a disk writing:

CODE:..............

What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:

CODE:.....................

My question is:
What could be a right MAX_MEMORY_SIZE value? Also, Is it a good approach? A good answer also could be: "Don't do it! SoftReference is already enough"

General :: How To Create SD-Ext Partition

I am trying to create an sd-ext partiton so I can move applications and backup to that partition on my 4GB external SD card.

I've got ROM Manager 4.8.0.8 but when I select Partiton SD card it reboots and tries to reformat but I don't see anything on the Card just a LOST.DIR folder. I can't read the system messages when in Recovery mode cos it all happens so fast.

I tried via ADB and booted into recovery and selected the option to partition manually but still nothing. I reformatted the card with FAT32. Nothing.

General :: Create New Partition On SD Card

Nov 6, 2012

I am having some issues with my Verizon Samsung Galaxy Tab SCH-i800. So the first issue is i tried to install a stock ROM to fix a corrupted cache partition. Now it tries to boot US Cellular. As of this moment the error i get when i put the device in recovery mode goes as follows:

E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/command
# MANUAL MODE #
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/recovery_kernel_log
[code]....

I am wondering if i can just create a new partition on a new SD card? i bought this device on ebay a couple weeks ago and i don't want to continue attempting sketchy leads for fear of hard bricking it. I am very good with performing commands via command prompt if that is necessary, also i have access to an Ubuntu 12.4 computer if that would make things easier? Also as far as i know this is equipped with android Froyo and the issue developed after the previous user attempted to update.

General :: Swap File - Partition

Dec 31, 2013

I just took over a second hand chinese android phone which appears to have swap enabled already.

The following is on the phone with SD card installed or removed completely

Terminal Emulator - Free - swap 196604 53036 143568
Diskinfo reports it as zram0 [swap]

The value of swap changes continually, so swap is active.

There is no swapper or any other swap app installed. How do I go about finding out how the phone is configured and if necessary undoing what was done and reconfiguring if necessary ?

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...
