General :: Boot System File To Switch MicroSD Mount With Internal Memory?
Jul 3, 2013
A long time ago I had edited a file that is read on boot, in that file is written which one of the two 'partition' has to be mounted as what.
Basically, my 32GB microsd is seen as the internal memory of the device (which would be 12 GB), and the other one as micro sd. The result is that most application would go to the microsd by default, using thus 32GB for apps instead of 12GB.
This is because my microsd is failing. Changed with a new one, and now it is failing again. I suppose my phone has become a 'micro sd destroyer'. Cannot do anything about it, so better to use the internal memory instead of the card for main use..... So how do I switch back to normal mounting (micro sd as micro sd and internal memory as internal memory and not switched up) ?

So recently I got lack of internal memory(it is only 512MB though) and I tried to swap internal memory with microSD(marked as sdcard2). However, Im noob in this and after changing the lines I understood, that I changed sdcard with sdcard2(swapped sdcard and sdcard2), however, my android system seems to be not working now. I can boot and access settings, but thats all. No menu, no apps, no anything. Empty screen, only settings accessible. I cannot access any files or anything...
What I tried:
- Connecting phone to PC as I have Android Commander program which can browse system files from pc, unfortunately, failed to connect.
- Factory reset. Didnt work.
- Recovery mode - tried all options that are available, didnt work.
The phone is Prestigio Multiphone PAP4300 DUO. When I boot to the phone, I unlock it and I get many messages saying com.android.phone, system and such things stopped working. When pressing HOME button, it goes to home, but its empty(empty screen) and tells Launcher stopped working too. All I can do is access the settings. Cant call anyone though.
What to say to warranty service when I will bring the phone to them. Can they recognize that its rooted/that the vold.fstab file is modified?
Specs: [URL] ......
That looks to be white, but mine is black. I rooted it only. Havent done any changes to the phone until yesterday - swap the memories.

The HTC Desire has limited memory of around 570Mb RAM and 512Mb ROM. The MicroSD card can hold up to 32Gb. So, why can't HTC allow apps be stored in MicroSD card? If HTC/Google's concerned about piracy issues, i.e. copies of apps from microSD card to another microSD card, etc. There is one way round to this problem: They could have installed some kind of unique crypto-key within the Desire's ROM, and any apps saved to the microSD card are automatically encrypted on-the-fly with this crypto-key.
When apps are accessed, it is decrypted on-the-fly, too. In other words, apps will ONLY work with THAT phone it shares the SAME crypto-key. Putting a microSD card containing apps into another Android phone will not work, thus solving the piracy issue. Therefore, a message to HTC: Please allow apps to microSD card (as much as 32Gb card) and BEAT iPhone/Nokia N900 at their game!

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.

1) If i download a movie file of 700mb, avi, can i just transfer to my microsd or internal memory and play the file flawlessly? I needed to compress file to play on my bold, or it would be extremely choppy. Also, what about a 720p video quality movie? file size 1.4gb, will it be choppy?
2) Is there an app on android market for the android forums? one that will give notifications when replies or messages are sent? i know crackberry had one on the blackberry, but was really just a shortcut to their forums.

i was trying to change the background for my x'pop 5035D cause i'm in jelly bean 4.1.1 and all the backgrounds for the system is white and it's very bad for my eyes specially at night ,
i was trying to modify framework-res.apk that exist in :system / framework but i couldn't so i thought i can replace it and i downloaded another frame work- res.apk and i used root explorer to replace it after taking a copy of the original file and since i did that the device restarted and stuck at the logo and i can't boot.
i tried every thing , i did nandroid restore and even wipe data / factory reset and the same result it just stops at the logo every time .

I have a HUAWEI Y300-0100, and it comes with a funny feature: every time it can't connect to WIFI a popup message appears saying that if you switch to data plan charges may apply.
I am constantly switching between WIFI/no-WIFI zones so that message really bothered me, and I searched a way to disable it.
Presumably, the only way to do that is by modifying a system file called "build.prop". I already had my phone rooted so doing so wasn't very hard.I used Jota+ to change a setting from "true" to "false" (ro.config.hw******), and saved the file in the root of the SD card. Then, with ES File Explorer, I renamed the "build.prop" in /system to "build.prop.bak" and copied there the "build.prop" I previously saved in the SD root.All seemed to be fine, except that after rebooting my phone it could not get past the HUAWEI logo.
Android recovery mode seems to work, but I don't know how to use a lot of its options nor I want to do a Factory Reset if there's a better alternative.Is there a way to modify system files before booting Android? I really would like to try to delete the "build.prop" file and rename the "build.prop.bak" back to "build.prop".

I have downloaded a file from HttpConnection using the FileOutputStream in android and now its being written in phone's internal memory on path as I found it in File Explorer
/data/data/com.example.packagename/files/123.ics
Now, I want to open & read the file content from phone's internal memory to UI. I tried to do it by using the FileInputStream, I have given just filename with extension to open it but I am not sure how to mention the file path for file in internal memory, as it forces the application to close.

Does anyone know how to access the internal storage memory using ES File Explorer? I have tried going up and down the folder hierarchy and can never find it.I've read that Astro File Manager can access it but I prefer using ES File Explorer and don't want to have two file managers on my DI.I am surprised at this stage of Android that a file explorer is not included in the OS.

Is anyone aware of a file manager that can read both the internal DINC memory and the SD card? Perhaps I'm missing something, but I've tried both ASTRO File Manager and ES File Explorer with no success.

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'm using an EVO LTE, but this question should apply on using Android device that has internal storage and an external card slot.
I'm trying to use my EVO LTE as my sole media player (specifically, the internal storage). Connecting it to the PC and getting the files onto it are no big deal (of course I do need to use MTP, which I hate). Now on to the problem:
I'd like to be able to use the device connected to my car's USB port. Being able to pick through my media using the car stereo controls is a big plus for me, and worked great when I had an iPod (which I don't anymore, not getting into that).
Of course, the car stereo's USB connection doesn't support MTP, only Mass Storage, at least as far as I can tell (It's a stock stereo in a Fit). I get a compatibility type of error currently when I try to connect my phone using the 'HTC Sync Manager' USB option in the phone (which mounts the device using MTP). The 'Disk Drive' option of course only mounts the external card.
what I'd love to be able to do is mount the internal storage via USB Mass Storage. I'm not sure if this is currently doable, but my forum-scouring to date leads me to believe that it is not.

Decided to try the encryption feature , it took well over 30 minutes to finish but never prompted me to enter a password, upon rebooting it prompted me for a password... didn't know it so I decided to wipe phone to be able to boot. Phone can not mount internal SD card at all.

I formatted my internal sdcard to exfat by mistake while trying to simply format it(for some reason windows defaulted to exfat instead of fat32) now my sdcard won't mount and I can't format it in windows and can't mount it, I could get it back to fat32 and working again.

I went and bought a new 8gb microsd card today, tired of not having enough music to get me through the day. Now, when I connect via USB, I get the normal options to mount and everything. When I choose to mount, the notification shows the option to turn off USB storage, but then just goes to preparing SD card and then I have the option to mount again. I thought that maybe it was the card, but now even with my original card, the same exact thing happens. The phone will read both cards, and both cards can be read in the computer. I also reformatted the 8gb, with the same result. Obviously I need to try another computer, but just curious if anyone has any thoughts. I have seen some people with other issues close to this, but not seeming to find the same issue occurring. btw, my phone is stock.

Please direct me to a description of the techniques that the ContentProvider employs to access data. I am trying to understand how it works as well as what is tunable or even if its meant to be tunable. It the memory management tiered, cached, virtual, flat? Is it file based, shmem based, stream based? Can there be a combination thereof?
Any information, suggestions, or references are welcome. The android fundamentals page says: "The data can be stored in the file system, in an SQLite database, or in any other manner that makes sense;" but the android ContenProvider page barely skins the onion.

When I boot up my Nexus One, it takes <Sandlot>FOR-EVV-ERRR</Sandlot> to mount my SD card. I've got most of my apps on that card, so it's super annoying!
Like I've said, I've got a bunch of apps (40?) loaded on to this card, a few documents, 4 CDs... random stuff. I haven't formatted the card in a looong time... nor have I wiped the phone in a loooong time. I am a crackflasher - I flash a new ROM every day, but I VERY RARELY have issues, so that's why I haven't wiped in so long. I would be happy to just mount the SD manually through the terminal when I need it to.
The phone is a Nexus One. I'm running a CM7.1(or whatever it is) based ROM and kernel. The SD card is the 16gig one that came with the phone.
What's the terminal command to mount the SD card to the phone? So the ROM can access it?

I'm trying to put my 6000+ mp3 collection on a 64GB microSD card (class10) and I can transfer them fine on my computer but when I go to view the folder on my phone it says there is nothing in it while my pictures folder (3GB) on the same card on the same phone shows everything fine. Using stock Android 4.1.2 on LG Optimus Pro G. Am I hitting some subfolder limitation or something?

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.

Not had my desire long but down loaded a few apps for it they all seem to be stored on phone memory not the sd card. what is stored to the sd card seems to be unused so far. do you have to set it up to use sd card or does it know one is fitted. does it switch to sd card when phone memory full. will run out of space soon if can't get things to store to card instead of phone mem.
