[Working] - A2SD (Apps2SD) v2.7 Update 3r1 on Aria - See Post #9

Hi Everyone,
Has anyone gotten A2SD from this thread:
http://forum.xda-developers.com/showthread.php?t=670087
To work on an Aria.
Please let me know.

I would love to know too. I'm tempted to try it, worst case scenario, I have to restore a backup.

It won't work with the stock kernel. Unless you can build a kernel to support it which I do not know how to it will not work for you.

this would be great, thinking of toying around with it myself.

I just go gave it a quick run through to no avail using rom manager to format the sd card into the proper partitions and then flashing the zip file in clock work as directed. I will try it again tomorrow when I'm not so damn tired. Apparently it works on the stock sprint hero 2.1 rom so maybe I'll research more into how that was accomplished as there is no reason this method needs a specialized kernel.

I've been playing with it a little this morning. It appears it is having trouble initializing a mount point in /system/SD. I will try a symlink from /sdcard to a created sir named /syste/SD until I figure out why the userland differs so much from the other ''stock'' 2.1 roms this appears to run on.

It won't work, the stock htc kernel does not support it.

Quit being a naysayer and read the list of stock based roms that support this particular method. There are several app2sd methods and there is no reason this one shouldn't support the stock kernel unlike the cyanogen style methods. I may not be able to do it yet but I defer the possibility of figuring it out to users who may be more skilled than myself rather than regurgitating the same thing over and over without research.

I have a2sd working on attn's liberated_aria b005
step 1: download Rom Manager from the Market
step 2: select partition sd card; select whichever size ext partition you desire (you can also create larger ext partitions doing this manually on a linux box but I won't cover it.
step 3: reboot phone into clockwork recovery; select partitions menu and mount /system.
step 4 (borrowed from Semigon at SmartQ MID forums):
Create a file called install-recovery.sh at <your android SDK installation>/tools/ on your PC with this code (MAKE SURE YOU CAN SAVE IT AS UNIX, ANSI TEXT , I use TextPad to do this [or TextWrangler for OS X] ) :
*
*
Code:
#!/system/bin/sh
mount -t ext2 /dev/block/mmcblk0p2 /system/sd
Step 5:
Plugin your cable and connect your aria to your computer so ready to use ADB
at prompt type:
"adb push install-recovery.sh /system/etc/install-recovery.sh" <-- push file to your aria
"adb shell" <-- shell to your phone.
*
*
Code:
* * #cd /system/etc/
* * #chmod 555 install-recovery.sh* * * * * *
* * #mkdir /system/sd
* * #mount -t ext2 /dev/block/mmcblk0p2 /system/sd* * * * *
* * #mount* * * * * * * *
( if everything is ok, you should see something like this:
/dev/block/mmcblk0p2 /system/sd ext2 rw,errors=continue 0 0 )
now type #exit
Step 6: Test to make sure that it will be automounted after reboot.
on your PC, from command prompt you can type: "adb reboot"
Step 7: After rebooted, you can either use adb or use "Terminal Emulator" to see if your SD EXT2 partition is mounted.
Connect as in step 1)
On your PC, from command prompt: "adb shell"
# mount
"/dev/block/mmcblk0p2 /system/sd ext2 rw,errors=continue 0 0" means you EXT2 partition is mounted after reboot.
Step 8: download Darktremor Apps2SD 2.7 Update 3r1 and place it at the root of your sd card.
Step 9: boot into recovery and select flash zip from sdcard
Step 10: In flash zip from sdcard, select the a2sd package file you downloaded earlier. Press home to flash; now reboot your phone
Step 11: now reconnect to your phone through adb.
#su
#a2sd install
Don't panic-- your phone will reboot as the script finishes
Step 12: adb back to your phone and type ls -l /data
You should see
lrwxrwxrwx root root 2010-07-27 14:56 app-private -> /system/sd/app-private
lrwxrwxrwx root root 2010-07-27 14:56 app -> /system/sd/app
Now check your phone storage. You should see that you have significantly more available then you did before. If you see it slowly decrease this is because the dalvik cache is still on the internal memory. This too, however, can be moved to the sd.
The following is from tkirton's main set of instructions found at hxxp://forum.xda-developers.com/showpost.php?p=7021325&postcount=2
If you want to move the dalvik-cache to the sd card, type:
a2sd cachesd (move dalvik to sd card)
a2sd cachepart (move dalvik to cache partition)
Now you should have even more internal space left. Enjoy.
Note: moving dalvik to sd card may produce instability in certain apps or force quits. If it isn't working for you just pull up "adb nocache" to move it back to internal storage while still installing apps to the ext partition on your sd card.

way to stick to your guns, ill try this later after i return from dinner

Please do. I'd like to know if it works for others as well. I can wait for a fully fleshed cm6 port with all working features (or a legitimate froyo for that matter), but additional space for applications is something that I desperately needed now (and now I do).

Just so happens this is the same day that CM6 from attn1 came out so i jumped the gun and ended up playing with his alpha Rom. So i have not validated this, BUT I can confirm apps2sd work on Attn1's new rom

Ha. I picked a hell of a day to try get creative. Hopefully it will be of use to someone until the cm6 build gets all its bugs ironed out.

dalvik cache issue
All of this worked fine, except for the dalvik cache part which had an error about not enough space while copying files.
How can moving dalvik cache be undone? It doesn't seem that "adb nocache" is a valid command.
Edit: Oh it should be "a2sd nocache" that seems to have fixed it

Well, I'm glad I have at least one happy customer. The cache transfered over fine for me but caused highly irregular behavior in 90% of the apps that cleared up the second I transfered it back. Could be a permissions issue or simply one that could be solved by reinstalling all your apps into the new sd environment. I'm not terribly concerned as installing the apps on the sd leaves plenty of space free for the caches to do their thing.

I am not very linux or android savy, but I will have to give this a try. It was the only thing missing from the Liberated rom. Now all is well. Thanks!
Hopefully, next we can get a Froyo w/ Sense UI! And our Arias can keep on rocking.

You may try the 2.7.5 RC1 and see if that helps the issue. There were fixes regarding copying files (permission issue...didn't tell it to retain permissions...didn't see that until 2.7.5 PF4A).
Glad to see you guys progressing on this. If someone knows the boot image base address for the Aria, I will modify a stock boot image for apps2sd.
Need any help, feel free to ask me. Any help I can give you to getting this program working on your rom I will be happy to do.

Here is a slightly modified version, mainly just changed formatting and fixed a few typos. Also my phone didn't automatically reboot after step 11. Thanks for the great guide!
Step 1: Download Rom Manager from the Market
Step 2: Select partition sd card; select whichever size ext partition you desire (you can also create larger ext partitions doing this manually on a linux box but I won't cover it.

mount -t ext2 /dev/block/mmcblk0p2 /system/sd
Step 5:
Plug in your cable and connect your Aria to your computer so it is ready to use ADB. At prompt type:
Code:
adb push install-recovery.sh /system/etc/install-recovery.sh # push file to your Aria
adb shell # shell to your Aria. Now you are at your Aria shell
Code:
Code:
cd /system/etc/
chmod 555 install-recovery.sh
mkdir /system/sd
mount -t ext2 /dev/block/mmcblk0p2 /system/sd
mount
If everything is ok, you should see something like this:
Code:
/dev/block/mmcblk0p2 /system/sd ext2 rw,errors=continue 0 0
Now type:
Code:
exit
Step 6: Test to make sure that it will be automounted after reboot. On your PC, from command prompt you can type:

/dev/block/mmcblk0p2 /system/sd ext2 rw,errors=continue 0 0
Step 8: Download Darktremor Apps2SD 2.7 Update 3r1 and place it in the root of your sd card.
Step 9: Boot into recovery and select "install zip from sdcard"
Step 10: Select the a2sd package file you downloaded earlier. Press power button to flash; now reboot your phone
Step 11: Now reconnect to your phone through adb:
Code:
adb shell
su
a2sd install
Don't panic-- your phone may reboot as the script finishes
Step 12: Connect with adb back to your phone:
Code:
adb shell
Then type:
Code:
ls -l /data
You should see
Code:
lrwxrwxrwx root root 2010-07-27 14:56 app-private -> /system/sd/app-private
lrwxrwxrwx root root 2010-07-27 14:56 app -> /system/sd/app

Sounds very similar to what happened for me. The script completed even with a few copy errors, but then many applications had FC after reboot. There is more than enough space from moving the apps, so it was not a big problem.

Will give the the newer version a try, by installing the new zip then running the cachesd and cachepart commands again. Thanks!

@MikeChelen Way to polish the tutorial. Looking good! I hammered that out in in only a few minutes originally after pulling together all the parts that made it tick for me. I just wanted to release it to the masses quickly to prove jznomoney wrong (am I a bad sport? Probably).
@Tkirton I will give the new version a go after lunch and see what happens. As far as the boot image address, I believe it is the same as the Legend, as almost all legend roms flash and boot successfully on the Aria. So I would give 0x12c00000 a try on Attn1's Liberated_Aria.

Haha, well I am glad you did! It meant the guide was available for me a little sooner. Score another point for stubborn resolve
It was more than clear enough for me to follow, hopefully the edits will help newer users though.
It might also be worth noting that ANSI is not an encoding itself, but a set of encodings? The normal Linux text editors seem to use US-ASCII or UTF-8 and these should probably both work.
Assuming other users don't have any problems, hope this gets added to the Aria sticky topic ^_^
Thanks again everyone!

[Q] How to mount SD partitions from eMMC?

In case it's unclear, I have CM7 on eMMC and am setting up a Honeycomb/Phiremod dual-boot on SD, and would like all three ROMs to use the storage partition (7th in this case) on the card. The following post suggests to me that it's possible:
racks11479 said:
No need to root your stock nook. If you have a CM7 sdcard, root explorer or file expert(free from market), and a terminal emulator app. Which you should have with cm7. Try the following steps.
-using root explorer or file expert. Mount system as R/W
-open up a terminal emulator and run the following commands
Code:
$ su
# mkdir /mnt/nooksys
# mount /dev/block/mmcblk0p5 /mnt/nooksys
-now exit out of terminal emulator
-open up root explorer/file expert
-navigate to /mnt/nooksys
-you should now be able to see the stock nook system partition
-open up the /etc directory
-long press the vold.fstab file.
-it should give you an option to open with text editor
-change the line where it mounts the /sdcard from auto to 4
-exit out of root explorer
-reboot to stock
-it should now mount the 4th partition of your sdcard
Click to expand...
Click to collapse
The file path specified, however, did not work, and I don't know enough about linux in general or the specific file structures to figure out the necessary changes. The system I want to redirect is the CM7.1 beta running dalingren's 5/13 OC kernel.
I also don't know for sure whether the above works for redirecting a stock 1.2 install.

[TUT] [Samsung GT-S5570] How Enable Darktremor Apps2SD on CyanogenMod 7

As always, DISCLAIMER applies!
Pre-install:
-Backup files on your SD (optional but recommended should anything go wrong)
-Make sure that you have a 2nd partition on your SD card. If none, partition using CWM or any other method
-Format 2nd partition to EXT3/4 using CWM or any other method
-Make sure that 2nd partition is mounted at boot. You can check this by typing the command below -
Code:
mount | grep sd-ext
You should see this
Code:
/dev/block/mmcblk0p2 on /sd-ext type ext3 (rw,noatime,nodiratime,barrier=1,nodel
alloc,data=ordered)
How to install:
1. Download Darktremor Apps2SD 2.7.5.3 Beta 04 and save it on your SD ==> http://api.viglink.com/api/click?format=go&drKey=1359&loc=http%3A%2F%2Fforum.xda-developers.com%2Fshowthread.php%3Ft%3D715940&v=1&libid=1311654060226&out=http%3A%2F%2Fwww.darktremor.info%2Ffiles%2Fa2sd%2Fdtapps2sd-2.7.5.3-beta04-signed.zip&ref=http%3A%2F%2Fwww.google.com.ph%2Fsearch%3Faq%3Df%26sourceid%3Dchrome%26ie%3DUTF-8%26q%3Ddarktremor%2Bapps2sd&title=%5BScript%5D%5BA2SD%5D%20Darktremor%202.7.5.3%20Beta%2004%20%5BN1%5D%20(01%2F29%2F2011)%20-%20xda-developers&txt=http%3A%2F%2Fwww.darktremor.info%2Ffiles%2Fa2s...a04-signed.zip
2. Reboot in recovery
3. Backup (optional but recommended should anything go wrong)
4. Mount system and data partitions (Main Menu > mounts and storage)
5. Install file in Step 1 (Main Menu > install zip from sd > choose zip from sdcard)
6. Reboot. Done!
NOTE: After the phones boots, it will reboot again. This is normal because a2sd will automatically move apps to the 2nd partition of your SD

thanks for your head up for creating a tut for it for those who find it difficult
offtopic:
but one thing again i want to mention that all this topic will slowly moved in back and will be difficult for mini owners to find untill n unless there is a seperate mini section in xda.cant we together pm the admin/mod/stuff and request them for a mini section by showing all the dedicated thread for it. just a thought.

Thanks for the tutorial!

[Q][TIPS]Nvflash, extracted system partition - gain root

Hi all,
is it possibile to modify the content of the files fills with the content of the partitions read from the Tegra of my LG P990 with nvflash?
I had read the partition from the board with
Code:
nvflash -r --read <-partitionID-> my_partition.img
Unix's command file said to me that the output file is data:
Code:
$ file my_partition.img
my_partition.img: data
But if the correct img file is provided to 'file', for example the file that nvflash returned when we asked it to read the partition 23, the APP partition, 'file' said:
Code:
23_APP.img: Linux rev 1.0 ext4 filesystem data, UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (needs journal recovery) (extents) (large files)
How i can mount this type of image file ?
Easily with the 'mount' Linux utility
Code:
mount ./my_partition.img ./tmp_directory
Now, if I add the su binary of chains_dd compiled for my platform in the system partition image file and after,
reflash the image file on my O2X I should able to get root, right?
It seems too easy...
Any help is appreciated.
Thanks!

Yes, it is "easy" like that. I made similar staff (extract partition image from official update, mount, extract selected files).
Edit: Only I remember that I need to specify mount parameters related to partition format and mounting access.

Have you really gain root access only by copyng (and launching ) su binary in xbin directory?

[ CM 11 EMMC <--> SDCARD SWITCHEROO] Modified uRamDisk

Hi everyone, I modified the stock uRamDisk for CM11 by decompressing it, editing the fstab.encore.rc file, and switching up the part with sdcard0 and sdcard1.
P.S. I removed the zram (compressed RAM) option in the fstab because the Nook Color has a crappy enough CPU as is, so it wont help with zram. Use a swap partition on SDcard if needed.
P.S.2. This ramdisk is from the most recent nightly build (Jan 11, 2015). It may or may not work with older CM11 builds.
It's attached here. It wont let me upload the file as is, so I renamed it to uRamDisk.7z; rename it back to uRamDisk. After that, follow these steps:
0. MAKE A BACKUP OF THE /boot PARTITION IN YOUR RECOVERY JUST IN CASE. If anything happens, restore the /boot partition's backup.
1. Mount /boot partition at /root (it's an unused mountpoint in Android)
adb root && adb shell
# mount -t vfat /dev/block/mmcblk0p1 /root
2. Change directory to /root, rename the original ramdisk
# cd /root && mv uRamDisk uRamdisk.orig
3. Copy over the new ramdisk
adb push uRamDisk /root/
4. Reboot and profit
The internal sdcard will now be seen as external. You no longer need to have an SD card inside to have many apps like Kodi (XBMC), Firefox, etc, asking for external SD.
If it doesn't work for you for some reason, remount the /boot partition again, and copy over the original uRamDisk ( # cp -f uRamDisk.orig uRamDisk ).
I used parts of this script to figure out how to mod the ramdisk: https://gist.github.com/aperezdc/6533546

1. Do you have adb installed for Windows? If not, do that first.
2. I don't know how to make a flashable zip. Someone else might. Anyone wanna do that? I don't have time atm since college started. Sorry for the late reply.
3. The instructions are about as simple as they get. You should study the "mount," "cp," and "mv" commands. They are, respectively, for mounting partitions, copying files/folders, and moving/renaming files/folders.
4. You can't rename the file because by default, Windows doesn't show file types' endings (like .exe, .zip, .rar, etc). You need to enable that. Google it.

hello, maybe you still have this nigtly cm11 system of 11Jan, 2015? thank's
