[Completed] How data2ext works? - XDA Assist

I have downloaded a rom for lg p500 optimus one, in the description it says that it has data2ext feature, but i don't know how it works, and how it expand the space for my phone, since it has only 198mb of internal, all i want to know is that can the apps be fully moved to partition using data2ext(I mean everything moved), and bit still confused if you press move to sdcard is selected in "manage app" does it automatically moved it to partition?
DO I need link2sd to use the data2ext feature of the rom?

[Q] link2sd vs built in

Ok in FB's kernel thread I asked is link2sd could be creating reboots when linking a app during a automatic update. FB asked why I was using link2sd.
So after some discussion Im confused. And not wanting to clutter his thread anymore Im creating this one.
My understanding is link2sd uses your current ext partition and puts apps in the sxt partition then symbolic links the app to the original location. That way you gain that much space on your internal.
FB says the built in apps2sd of android does that already. But I was told all it does is move the app from the internal to external (sdcard). This is possible even without a ext partition, I know because several people with the Optimus V do not use link2sd or anything like it. They just use the built in app mover.
When I had my Optimus V I used this data2ext but I do not think it would work for our phone since its written for CM7. WIth that my interal memory showed up as however much my ext partition was minus the apps. What it did is trick the OS into thinking the ext partition was really the internal storage.
My question is am I right in how link2sd works or am I misunderstanding?
Is there a version of the data2ext that works on the SGS4G roms we have and I just cant find it?

How it works:
Link2SD mounts the second partition of your SD card as /data/sdext2 and makes OS mounts it at boot time.
When you select an application and press "Create Link" button you can select which files of the application will be linked and moved to SD card. Apk, dex and lib files can be moved and you can select all three or any two of three or even only one of them.
Depending on what you select, Link2SD moves apk file, dalvik-cache (.dex) file and lib files (.so) to SD card's second partition and creates symbolic links in original directories.

apps2sd does NOT require repartitioning your sdcard and it's an Android 2.2+ feature.
links2sd requires your sdcard to have at least 2 partitions + formatting your sdcard, and is a 3rd party application.
Ok I understand that. Don't we need a ext partition anyway? IM trying to wrap my head around this but I'm still confused how the built in moves the app to the ext partition.
I'll read more of that thread tomorrow stupid ISP OS doing maintenance and my net is crapping out.

First of all, what do you mean by "ext partition"?

I think what eollie is looking for is what we had on Froyo. Remember dsexton's ext4 guide? We could create a second (ext4) partition on our EXTERNAL Sdcard and use Link2sd to move apps there..
On Froyo I had a second 1.5 GB ext4 partition on my EXTERNAL sdcard and used Link2sd app to move my apps to that partition. It worked Great and I miss having it on Gingerbread. I could not get dsexton's guide to work on Gingerbread at all. It caused me all kinds of problems. Even soft bricks..
Sorry if I'm wrong eollie.
On my old Milestone xt720 I used link2sd primarily before 2.2 was available for the phone. It involved setting up an ext4 partition as well as a linuxswap partition.
At this point ... seeing as we have gingerbread which already moves most apps to sd card ... the only advantage I can really see is that when you use links2sd you can move absolutely any app to sdcard (keyboards, alarm clock, ect) that would not normally be moved.
Now one thing to be cautious about when using links2sd is some apps will not work properly when on the sd card. This is especially true with apps that have widgets. For example - if you move your digital clock to sd card the clock widget will not display.
I don't know if this will be helpful but I just thought I would offer my input.

You are correct.
The link I posted is what I used on my Optimus V. It tricked the phone into thinking that partition was the internal memory.
Like jiggleynuts (that name kills me) said you have to be careful with what apps you put on the sdcard. I was using that but when I update apps it would move them to the sdcard if they could be. And my apps that have widgets I use were breaking cause of it.
Again if we can use something like the data2ext I linked to then I would scrap link2sd faster than you could blink. I hate having to use a app when there is a alternative like the data2ext stuff.
Am I wrong in thinking the ext support we have is the same as what the op in the thread I linked is talking about?

eollie -
did you ever get the data2ext mod working for the t959v?
i remember you from the optimus v forums last year.
correct me if i'm wrong but we used the data2ext mod with bumblebee and harmonia? i'm considering trying that data2ext v7 mod on this device. i'm actually really surprised that mod isn't being used with this device like it was with the O-V. Both have limited internal memory. maybe i've not learned enough about this device and it isn't capable of utilizing the mod. i'm kinda curious why darktremors app2sd mod isn't used either. its an easy option in the kitchen. either way i'm curious what you've found out or experienced with these mods. i do know link2sd works with this device, so i'm assuming data2ext and darktremor app2sd would too.
I replied to your pm. But Ill answer here too, I never found a conclusive answer. So I just move apps using the built in android app2sd function. If there happens to be a app that needs images loaded at boot like launcher themes or the such I just move it to internal memory.
ok cool. i may try it. i dunno.
thanks for your response.

Any solution for Low Internal Space?

Heyy Everyone,
I am running CM9 ROM on my HTC Chacha,is there any solution for low internal memory?Can i install apps directly to Extsd instead of Internal memory,please anyone help me..it's really Annoying
Wrong section. This is a question for General. And yes, there is. You can also find solutions in the CM9 thread (I wrote one of them).
Where is that tutorial and does it apply to HTC Chacha?

It's not a tutorial, but basically amounts to install Link2SD.
I myself use D2EXT from here:
http://forum.xda-developers.com/showthread.php?t=1716124
It works nicely. But don't delete dalvik cache with it installed as you will get bootloops. It's not hard to fix, though, but you will need a computer and adb installed. So just don't delete the dalvik cache and you will be fine.
To install it, you will need to partition your SD card and create an ext4 partition. You will lose everything on your SD, so make a backup first.
Use the guide on the link I posted . You will need a fast SD card.
And next time use the general forum.
Good luck.

[Completed] I've paid for link2sd plus but it doesn't work!

Hi,
first of all sorry for my english.
I like very much your app. I use your app in all phones. When a friend asks me how can he boost his phone, i suggest him to install link2sd because is the only app that move all apps into external sd.
But i have a problem. In my phone, when i have upgrated to KitKat version of Andoid, Link2sd doesn't work with the second partition. I've tried to format the second partition in ext2, and Link2sd said me that "script cannot be created".
I've tried to format the second partition in ext3, but it was the same. I've tried to format the second partition in f2fs, but it was the same.
Only in ext4 Link2sd can create the script and it can see the second partition!!
But when i link an app to the second partition, it doesn't and say me "reboot the phone".
When i've rebooted the phone, the app that i've linked is corrupted.
I researched on internet and it seems that is a problem of Kitkat that prevent to write in the external storage. So i've resolved this problem with this tutorial --> http://forum.xda-developers.com/showthread.php?t=2524277
But Link2sd still does not work....
My device name is: 706v92_jbla_fhd
Finally, i want to say that with Jelly bean version of Android, Link2sd was perfect and it worked very well. Now, with Kitkat Android, i cannot link apps to second partition!!
What can i do??

[Completed] Help for LINK2SD Second Partition

Hello, I am Prakhar Mishra, and I own a Micromax Canvas Viva a72. It runs on Gingerbread. It's internal space is really low. Before this, I had rooted it and made a second partition and used Link2SD for storing apps in it. It worked perfectly. Today, I factory reseted my phone, formatted the SD card and create the second partition like before (Ext2). Now, the system detects the Ext2 Partition. But LINK2SD doesnt detect it. It says Failed to create mount scripts. I followed all steps and created the second partition numerous times as Ext2, Ext3, etc. I even tried to use another SD card. But I have the same error. My phone is rooted. Please tell me if there is any solution to this problem, I really need LINK2SD for linking my app's data.
