[MOD]Creating EXT4 Partition for sgs4g

Hello wonderful sgs4g community, i hope you are all excited about all our new stuff as i am. Anyways now that drhonk has built ext4 into our kernel we can now go ahead and do SOME ext4 mods. here is the guide on how to create an ext4 partition so that you can use the link2sd app so:
A:you can have an ext4 sdcard filesystem
B: create more internal space for your apps(takes away even more bloat)
Here is what you will need:
A computer
MICRO ADAPTER or USB CABLE to plug into the computer
drhonks new 2.1 bali kernel
mini tool partition wizard(or any other program that does this) you can find it here: http://download.cnet.com/Partition-...62200.html?part=dl-6285158&subj=dl&tag=button
link2sd apk you can find that here: http://forum.xda-developers.com/showthread.php?t=919326
Now go ahead and mount your sdcard to computer with the micro adapter
go into mini tool and click on your sdcard
press move/resize
go ahead and resize from 256mb 512mb or 1g off from your original size
THE UNALLOCATED WILL BE THE SIZE OF YOUR NEW PARTITION
now go to the unallocated amount and press create partition
make sure that you do ext4 and make sure it is PRIMARY not logical!!!
press apply!
bam you go ext4
now put your sdcard back in and go to link2sd
it will tell you to go into recovery and mount your sdcard
sooooo
go into cwm and go to mounts and storage then make sure you have your sdcard say UNMOUNT
reboot
go back into link2sd and click ext4 when it pops up,
NOW move all the files THAT ARE NOT SYSTEM FILES(which it wont let you do anyways) and your all done
afterwards you should have from 375mb to 440mb of free internal space
have fun
Thanks to:
Fknfocused for pushing me to do this
drhonk for the kernel ext4 patch
wizard(i saw he did the link2sd first so i decided to do it)
and the rest of the community for being awesome

Thanks brotha! im doing this right now.

it doesnt effect app2sd and to be honest you dont need app2sd after you do this trick, and im not positive about widgets i think they might be safe though

Uhh thank you for posting my name there )) well it works ... if you guys want and know how to use linux u can do it from there too ... if anyone needs help ley me know ...
Link2sd is only way I thought off to check if kernel mounts ext4 ...damn glad about that faulks

I used ubuntu and gparted inserted the mini sd into the adaptor created the partitions then placed it back into the phone and ran links2sd worked like a champ did that this am your way seems easier good write up

ok i did something all wackey... lol for some reason i can only see 1.89 gb of my sd card on my phone and on mini tool partition it shows that i have 12 gb in fat32 and 1.89 gb unallocated. there is nothing i can figure out on how to get the two partitions of the sd card to join back together. even the minitool thinks they are two seperate devices. does anyone know what i can do to fix this and start over from the beginning? sorry guys im a linux newbie but i am having fun while learning.

So will this work also on drhonks uv version too?

[Q] - Move to SD enabled for (almost) all apps by?

Noticed today I'm able to move almost all of my apps to SD and not just the supported ones without having done anything but installing a rooted stock ROM and some standard goodies (SU, BusyBox, ROM Manager and Titanium Backup). Wondering if it was enabled by any of the above? the rooted ROM? or the stock ROM?

any takers?

Titanium backup, in "batch", has option to move all apps to either sd or internal memory.

It's not true A2SD. Just a bunch of buggy symlinks in /data and incomprehensible files in /sdcard/.android-secure that Google is trying to pass off as A2SD.

thanks. i rooted my phone right after the first stock boot so i couldn't tell if it came that way. It's just odd coming from 2.2 that everything all of a sudden is now movable, despite being not true a2sd.

I know. Just because a bunch of people find hitting "partition SD card" in ClockworkMod Recovery too difficult doesn't mean those of us who want the full potential of our phones unlocked should suffer, but we're stuck until someone finds us the mountpoint for sd-ext.

you all need to check out link2sd (free app) it will let you install apps to ext partition. I myself use it and have a 8gb ext3 partition with over 550+ apps/games installed. It also lets you decide if you want to move dalvikcache and library files to ext to save more internal space. I used mini tool partition app on my pc to create a larger ext partition then cwm would allow.

WIP Memory Address Listing
You need to know where to put and access the data, explicitly, in order to be able to use that location.
Android does this by using mount-points, which translates to the memory address where it should be looking for the information.
The thread I linked to is one I started so that we can discover them all, and what mount points correspond to what memory address.
Please make sure to read post number 8 in the thread by dhkr234 which spells out a good caution about using memory addresses directly and why you should be using mount points instead.
If anyone makes any headway in learning anything we don't know so far, please post it in that thread so we can get a comprehensive listing of mount points and what memory addresses they correspond to.
I've been extremely busy on other projects, but if someone is going to come by and make A2SD available for us, having a road-map for them to follow already sitting here will make their life a lot easier. ( ...and maybe encourage someone to do it because the info is sitting there. )
...and yes, it is specific to our device. Every device addresses the internal memory differently and that makes the mount-points unique to each and every device.

gotcha, so...piecing this all together, does that mean that a true A2SD shouldn't rely on symlink at all and Link2SD (what d12unk13astard recommended) is essentially just another hack?

The real A2SD is not "just another hack," it's one of the ORIGINAL post-root hacks pioneers like JesusFreke came up with. It allows you to put your apps on an EXT partition of your SD card, and you can resize that partition if your computer runs a Linux distribution.

dhkr234 said it good there.
I linked so someone who wants more of an explanation can follow and read up.
In short, you can very easily write to the wrong memory address.
This means:
Installing some silly game over parts of both your boot partition and recovery partition would give you a cool slide-paperweight.
Mount points prevent this from happening by ensuring the data is written to the proper memory addresses.

CWM ExtSDcard support?

Is there any way on the gs3 to save your nandroids to the ext SD card?
Mine shows the option greyed out.

If you booted into CWM using the EZ Recovery app then you would notice that you can manually save backups to either sd card.

It might also be that you don't have your external card formatted to fat32. CWM doesn't like the exFat format that I believe all big cards come in.

If your talking about rom manager then yea thats normal!
On a side note, I recomend flashing files manually in CWM recovery...you would not believe how many threads I have helped folks get out of a softbrick or bootloop situation by flashing with rom manager. The app works great, but you still need to know the background information on what your flashing! To many people think since they can pull the file up on RM, it must be compatible, or they flash with the wrong recovery = soft brick! Part of the main reason my guide is written in its fashion...provides proper instructions to flash, makes one read a bit, and repeats its self to pound the info into ones head. Not tryin to preach to ya, just wanted to share some possibly useful info to yourself and others. thx

I was wondering the same about saving to external from rom manager. So our only option it looks like is to boot to recovery and manually go to save it to the external sd?

Yeah that's what I was saying. And I don't flash anything with room manager lol. Just bought it back when I had the OG droid and then I seen that option so I was just curious.

[Q] Root/SD card question

Ok, so I've rooted my Wildfire S, flashed CM7 on it, with the updated gapps files (gapps gb)
My question is this...Do I need to keep all those files on my SD card? Or can I remove them?
Also, having an "H" icon for my data is better than 3G, correct? everything I've read says that, but I'd like to know from a DAMN good source (you guys)

If you've installed all packages you shouldn't need to keep those on the sd card, but best to keep them on your computer in case you need them in the future.

Yeah the 'H' is for highspeed access, you'll get that in areas where you have best reception.

Thank you very much. Yeah I still have them on my computer, along with my backup.
I also have one more question, how do I make a partition on my SD card? And should I get a bigger one? I currently have a 2gb
Sent from my Wildfire S A510e using xda app-developers app

Not exactly sure of the context. Why do you want to create partitions?
If you are wanting to create an .ext3/.ext4 partition on which to install apps (I know people did this with the HTC Desire, because of the really low amount of onboard storage), the best tool for the job is a Linux based partition editor called GParted. Just download the live CD iso, burn it to a CD and boot from that.
You should get a new SD card yes.
A 32gb card will run you ~$20 brand new on ebay, just make sure your phone supports that capacity

Link2sd says to make sure you have a partition created on the SD card for whatever reason...I uninstalled it, and forgot what it said, but yeah....same reason. 512mb onboard storage = pure sh*t.
Edit: it says to do that for "symbolic link" whatever that means.
Sent from my Wildfire S A510e using xda app-developers app

Sure, well most apps like that will want an ext4 partition, which like I said can be created using GParted. Plenty of tutorials on youtube I'm sure for using GParted

Ok, thanks for all your help! It's greatly appreciated!

[Q] HELP!

ok i have a samsung galaxy stellar / sch-1200 from verizon, cant find a forum on it so i figured this would be closest hopefully.....
it reads internal storage as "sdcard01" and i also have an 8gb external sd card. the phone itself does not have an option to move app 2 sd card in the application manager.
ive tried app's via the playstore and still no avail. app2sd and others..
my question is.. is there an option somewhere in the phone that i cannot seem to find or a way to get it to default save items/pics/mp3s/ect to the actual sd card??
ive looked all over to try to find out some similar problems and cant seem to find any info besides actually swapping the external to internal and vice versa using ADB.... i do not have this phone rooted and wont until warranty is up. if anyone could point me in the right direction or inform me on how to change the storage settings id really appreciate it.
thanks in advance.

Wrong phone and carrier... at least you got the Samsung part.
Edit: read the phone and posted. Sorry

no not yet.. i will be rooting it in the next couple months but as of right now its not unforunately. its like the phone doesnt even recognize the sd card it in even though it is mounted and reads pictures and music that i manually put on there. but the application manager doesnt even have an option to "move to sd"

I don't know. Maybe it is mounting as read only. That is what happens on the xoom

shouldnt be.. i can move individual files that i have downloaded, its the weirdest things ive ever came across..
my og droid was rooted and my htc inspire, they both even before rooting had the option to move apps to the sd card. the phone has 2gbs of internal space so its not like its worse than the previous just blows my mind and i have no idea how i could maybe change it to having the external card being the primary storage. under Astro it says there are 2 sd cards... i know its thinking that the internal storage is the first/primary card. just dunno how to get it to switch over i guess..
thats the best way i can think to describe the situation..

For moving pics and music and such I would think a file browser like es file explorer or something would let you move from one storage to the other. I dunno that you would need root access for that. But apps are a different story.

yea the file parts im not real worried about. i am able to move them and everything.
i might be not able to really explain it the way im wanting to. its reading like there are 2 sd cards when there is only one in the phone. so the primary storage is to the internal (fake sd card) so it wont move apps to the sd card to free up internal space. thats my assumption anyway. so i thought there might be a way to change the primary storage but i havent found a way to. if that makes sense.

yeah there are external2internal swaps or whatever but I'm pretty sure you're gonna need root and custom recovery to do anything like that.
