benefits and method to create a partition inside internal memory ..

i read on some forums and on this as well where people were talking about sd card and internal memory etc, it all go jumbled up, but what i know is somehow we can create a partition inside our phone memory as it helps apps, \
please correct me if i am wrong and tell me how to do this

So basically you heard something one time, have no clue what it is or why it's beneficial but want to do it? I see no flaws with that logic. Especially when it's involving partitioning. You should make a bunch on your computer just to see what happens. /s

Not sure what your goal is.. but afaik that app is useless on Gnex, or any device lacking external storage. Delete app2sd and you wont get that message anymore.

app 2 sd is not useful on the nexus at all. apps and system all use the same partition.

If by any chance, is it possible that you were instead looking for "Link2sd"...?? cz app2sd is neither required, nor usable on Nexus.

The app developer should have blocked installs on devices with a "virtual sdcard". I checked playstore, i can see the app and it allowed install; it shouldnt do that.

thank you all of guys for answering it , i think i got confused, actually i thought it might partition my phone internal memory so i can use some apps may be exclusively,, is there any way to do that

[Q] Data recovery on Xperia S (rooted)

Hi all,
Just wanted to start by saying, big thanks to DooMLoRD and the rest of the xda-developers forum for providing me the tools to get root access to a friends phone, who has recently accidentally deleted all their photos and videos. If we are successful, I'll definitely be suggesting that they make a donation to Doom for his epic contributions
I'm trying to help them recover the lost media. I know that typically performing data recovery on a phone requires root access, so I have gone ahead and done this. On with...
My question:
I've got an Xperia S running Jellybean (4.1.2) which is rooted. However attempting to use my data recovery tools on the phone, the device is not shown as a storage device. As you may well be aware, the S does not come with external storage. The S also has the 'mass storage mode' removed. Nice one Sony, give professionals another reason to avoid your products in the future...
I don't want to Flash the phone since any added files will start destroying the potentially recoverable data (plus I'd simply rather not format the phone if possible).
Is it possible to mount the internal storage of the Sony Xperia S as a drive so that I can run my PC based data recovery tools on it?
I imagine App Store apps are too lightweight to handle a file-based undeletion. If I could just see the device in my recovery apps I'm sure I'd be in business! I've attempted Recuva and R-Studio.

Doing some more research (like a good little n00b) I imagine I'm going to need SD Mounter.
I'm a little thrown off because 'SD' usually describes SD cards (of which the Xperia S has none). Also, the screenshots (for SD mounter) seem to indicate it's for ICS so I'm not sure if there's going to be a compatibility issue there.
Am I barking up the wrong tree by making this assumption? Should JellyBean have access to the mass storage and the option is simply not showing for some reason? Anyway, I'll continue working under my assumptions until someone suggests otherwise...
To get SD Mounter running, I'm going to need BusyBox. The problem is, I'm trying to read the BusyBox installation FAQ, and I'm finding it very vague. Like...
and save it under the name "busybox"
Click to expand...
Click to collapse
but it does not specify WHERE. Make a folder called 'busybox' on the root folder of the phone? Somewhere on my PC (the page suggests its for the PC rather than the phone)? Also I'm seeing Linux-looking command lines, but I'm on a PC... can I run this via the command prompt in Windows? I downloaded the 'binaries' like it said, but there aren't any executables in here...
Can anyone shed some light?

There's an app called BusyBox Installer, that installs it correctly on my Xperia S. That SD Mounter app works perfectly on 4.1.2, though. I use time to time. It just messes up a bit with Media Scanner, requiring me to do a reboot on the phone to make it work again.
I wish you lot of luck trying to recover your files. I once tried something like that, but came unsuccessful. There were some media I wish I had saved, but it wasn't THAT important, so I just gave up.
Suggest to your friend, though, to get an account on Mega, Box.net or Dropbox. All of them has auto backup of camera media to the server. All of them has options to backup only on WiFi, and even when charging only. The first two has 50 Gb of free storage for life (Box, you just need to sign with your Xperia device), and the later only 2 Gb, but you can get more and more with promotions.
Alternatively, he can enable the Google+ Auto Backup. There is 15 Gb (shared with Gmail and Google Drive) for pictures on original resolution or unlimited on 2048px, compressed. On Google+, though, you have the Auto Awesome, which make some awesome images.
Hope it helped. If I can help any further, just tag me

I see 'BusyBox Installer' in the Play Store, is that the one? Seems strange that the Play Store would add an app that requires rooting. Just wanna make sure I shouldn't be looking for it somewhere else (plus I'm away from that phone at the moment)

That's okay. I've warned them this process might even brick their entire phone. They are prepared (I hope) for complete loss/compromised apps

As I'm a lazy person, who can't find a way to break quotes into multiple parts (serious, how do you Do that, without having to write the quote code every time? It is not much, but I'm really lazy, so yeah.
Yep, that's the app. There's no reason for Google to block root apps. It's a function of the OS itself, just hidden from users. It's one of the easiest things to do on a Nexus device, after all. It's hidden because, if used without caution, can soft brick your device. But, don't worry, that shouldn't do any harm. At it least it hasn't with my device until now haha
As I said, I had already lost lots of stuff, and I didn't bothered much to go any further to recover it. It was a simply Install Recuva, run on the SD card and see if I could restore anything. Nothing? OK, no worries. As you already mentioned in your first post, avoid at all costs writing new files to the SD Card partition.
About the lecture, yeah, I imagined you had already told them, but it doesn't hurt to tell anyway.
About the SD Card on the Xperia S, another technical info you might or might not know, and also doesn't hurt to tell. Until Android 2.3, devices with a big internal storage required a partition for cache, one for data (apps and their own data), one for system, and one SD Card. The last one in Fat32 (plus others, but those are just too small and insignificant, for most, anyway) Think of a normal hard drive with plenty of partitions. Since Xperia S was developed (and launched) with 2.3 (one of Sony's biggest mistakes with this phone), it had to follow those "guidelines".
With Android 4.0 and beyond, the above mentioned data and SD Card turned into one partition, in Ext4 format. That data partition stores both apps and their data, and also other types of media, like media, documents, and etc. That storage goes into a mounted folder.
Anyway, again, wish you good luck. If they aren't very close friends/relatives, you should charge some money for all the hassle if you recover haha

Not in Xperia S case. As I said, it is on Fat32, so it is easily mount-able on Windows.
On any phone with Android 4.0 or more, you'd need a Linux to do the recovery. You can't format it, or else you will turn the device into a really expensive paperweight.

For future reference, It's customary and relevant to mention what rom/build you have when asking for help. Also titles should be descriptive/specific not braud/generic. For example, better titke would have been "SD card is write protected"
PS. If you had used search (like you're supposed to) and used the descriptive title as your keywords you would have found your help already exists.

[Q] Files protected despite root&SDFix working?

Hi everybody,
I have rooted my M8 Dual Sim and according to SDFix disabled the limitations to use the SD card in my phone freely. Almost. Moving files around within ES File Explorer is no problem, neither copying files from PC to the card.
BUT: when I open a file on either the phone's memory or the card from the PC, the files open all write protected.
This is what drives me mad, I would like to open the files, write into them, and save them like in a normal environment. Does anybody know how to disable this write protection? Please help. Thank you.

Nobody misses usm on his m8???

Its been reported by users here that the SD fix apps don't work on the "regular" (single SIM) M8, so I assume the same is also true with the dual SIM. There is a custom kernel module that fixes the SD limitations, but again not sure if it works on the dual SIM, or if there is a corresponding mod/hack.

SDFix has been used only to check whether I gained access to my SD card. And, according to the possibility to move files freely, i gained full access. Only that my files opened from he PC are all write protected.
I can copy&move files from internal storage to SD card and viceversa, and I can copy and move file from PC to SD card and vicecersa. But the files located on SD card, when opened from the PC are always opened in write protected mode. WHY???

Almost seems like a permissions issue but I'm not sure if the device would automatically apply permissions that will have you only "read, write and execute" those files on the device itself and not on the PC. That's probably something that you'll have to "set" yourself.
All the files that I create, pictures that get taken etc all have it as "read and write" which is why we can view it on the pc, but in your case it almost seems like it saves it as "read-only" preventing you from making any other changes. BUT that's how it looks and it might not necessarily be the issue at hand

Change permissions?

That makes sense, thanks BerndM. Any hint on how to chance permissions easily, without having to flash custom ROM?
To be more exact, I am talking only about doc(x), xls(x), txt files, nothing executable.
Truth is, only the windows explorer can handle the files, opening a word file and trying to save it directly from the program to the SD card isn't possible. But I guess you knew that already... I don't recall how it was with my last HTC (the HD2), but at least I could save an opened file in its original storage.

If you have a USB card reader, try to connect to your PC and format the card. I'd suggest FAT32 as its the most universal; although ExFAT should be supported by the M8 (but only really needed if you have huge files).
I've seen a number of folks on here have various read/write issues with the SD, even when the card works perfectly on other devices. The permissions issue is a logical conclusion, but might just be a wild goose chase. Reformatting the card sometimes solves the issue. Even using the phone to format the card doesn't solve the issue, when formatting on PC works.

Actually, I'm mixing this up, the kernel module is to disable system write protection, not SD write protection. I'm having a brain fart on how to do the SD fix.
But as mentioned, this might not be the OP's issue anyway. At least, I don't think so based on the described symptoms.

Hi there, @redpoint73 if you could provide some guidance as how to get a hold of that insecure kernel, I'd certainly be grateful. A link would be a boon.
I'm trying, with no avail, to edit hostapd.conf (my hotspot configuration file). There are a few options on it that I can't switch on a GUI, like SSID Broadcast and 802.11n toggles. Also, my hotspot has a difficult time upholding the wakelock it needs to stay on without a data interruption at screen off. I don't know if Amplify (by Ryan Steckler aka "cryptyk") might be to blame, because I haven't told it (and isn't) restricting Wi-Fi related wakelocks at all.
Please check my signature below for any details you'd like to ponder. Good night.

Post to that thread, and see if the OP can re-post; or if another user can post it.
But I just noticed your are running CM11? Custom ROMs should already have this implemented, or not applicable in the first place (AOSP?).
