You need to have your SD card partitioned properly. Also A2SD is automatic so you dont need to do anything.

i partition ext2 & upgraded to ext4 already. it shown success. i dont know which method i done wrong...

idk how you did it, hopefully with the recovery image menu. then you did it right.
what you did wrong was executing a2sd manually. all you need to do is partition your card and flash mcr3.1, that's why it says "automatic" in the description.
instructions for upgrading the recovery image are in the first post of the recovery image thread.

i do it auto & the apps doesnt install on the sd card that y i do it manually >.<"

i just do a wipe & re flash everything but when i install apps it still use my phone internal memory.

Some people say that small chunk of app is still installed in phone.
But I think only small chunk is installed in sd card but large portion is left with phone memory.

mine all in internal memory -.-"

can you tell us what makes you come to this conclusion?
please post the output of
Code:
adb shell ls -l /data/app
and
Code:
adb shell mount
while the phone is turned on normally.

edit: remove of image as is wrong command

As for my recovery upgrade i was just able to flash to recovery 1.5.2 already. due to ext4 issue after i follow the code: tune2fs -E test_fs /dev/block/mmcblk0p2
when i free will re-flash modaco 3.1 to try the a2sd again. hope i able to do it this time...
Would like to know after flashing rom, was it normal that my hero keep on reboot non-stop? should i remove the battery? or should i wait?(so far i always remove the battery as the reboot will never end after more then 30mins-1hour)

you didn't get the first command right, please try again just to make sure. the output of "adb mount" tells us that you have an ext4 partition on your card, which is mounted to /system/sd. the first command (if entered correctly) will most probably show you that /data/app (where apps are installed) is a symbolic link to /system/sd (a.k.a. your ext4 partition). if you had searched for the problem this would not have been necessary... and you could have found the explanation why the internal memory is still decreasing.

Hope this is the correct command:
As i just do a re-flash mdc 3.1 on recovery v1.5.2.
now i still unable to install app in my sdcard as my internal memory is keep on reducing while i install apps.

Hi kendong2, i dont mean to **** around but as my internal memory is keep reducing as i installing apps.
i go setting sd card & phone memory. after i flash the mdc 3.1 the phone memory is show as 151mb. but after i install some apps it now shown 137mb. so i use the widget of internal memory it show 28mb of 165mb was used. was it my phone status & the internal memory widget error? im confuse now...
so sorry if i pissed you, as im not expert on all this. i was just simply follow the method on website. i just do a step by step as i dont know the step stand for what use... & im not well educated too, so sometime some part i dont understand. but i willing to read & learn so i post my question to ask so in future i will understand it... as much as im able to...

How do i Install apps2sd after rooting with unrevoked

Hi, I have searched for the answer but cant find it
I rooted with unrevoked yesterday and installed the clockworkmod recovery as well.
i downloaded r1-a2sd-desire-dalvik-fresh-signed.zip
and put it on the root of my sd card
i then entered the recovery wiped data and cache which wiped and tried to wipe dalvik though nothing appeared to happen.
i then tried to flash the above mentioned zip of apps2sd
it starts flashing but then comes to a message saying...
can't symlink system xbin failure at line 5 symlink busybox
so what am i doing wrong?
any help would be much appreciated.
i have a nandroid backup.

I tried for ages to get a2sd on my stock rooted desire. I used several guides all of which failed somewhere.
In the end I gave up and installed PAYS 2.1 ROM with Sense & A2SD. Works fine and looks pretty much like stock.
Use Recovery mode (Push from Windows) to format SD Card with 0MB Swap, 512MB Ext and the rest FAT32. Upgrade the ext2 to ext3 then use ROm Manager from Market to install the new ROM.

Yes, this was what i had been thinking i would have to do. do i need to flash a new radio for pays?

Been trying to do this also.

I think your best very is to use rom manager or I believe you can do out using the amon ra recovery.
So can any one help me install apps 2 sd?

Ok so the update is I can now flash the zip but my phone then hangs whilst rebooting and I have to restore from nandroid

I have a problem also.....
I used rom manager to partition my sd card and can install apps on the sd card but when i reboot...the apps installed on the sd card have disappeared.
Anyone help?
Cheers.

Disappear you mean shortcut only or the whole app?
Do you have an ext3 partition?

I backed up my sd card to pc then used rom manager to partition card then copied my files back to card, then i go into settings and set for apps to be installed to external.
Next i go into market and download an app and it installs itself on the sd card and i make a shortcut on the phone.....everything works fine.
But after a reboot, the shortcut had disappeared and the app is not listed in my "all Apps" but still shows that it is installed if i go into market.
I have this problem with all roms.....i don't know what i'm doing wrong.

The way I understand A2SD and Froyo's app2sd, when you install A2SD/+ enabled rom and partition your sd card, you don't have to set up anything.
It "tricks" rom to use ext partition as part of internal memory, and stores everything it can in ext partition (A2SD storage).
It always worked for me, and you can check this by installing quick system info app from market.
It will show if your ext partition (A2SD storage) is being filled with data - check out this pic that I found with google:

this is an example of worrking A2SD, if it doesn't work, or you haven't partitioned you card, A2SD storage will be unavailable.
Once you choose setting for the apps to be installed to external, you manually switch to Froyo app2sd, which is inferior way to store your apps on sd card. That's why it didn't work for you.

Thanks for the info
I will try again....my phone says A2SD storage -information not available
Cheers.

[Q]Hboot CM7 r2 problem? (with Coolsense 3D Aces v6 Bravo)

Hello i am an old user of this superb forum, but now i must write my first problem, here we go:
I got a problem about free space when i use CM7 r2 hboot.
as we know we should have this configuration:
/system=145 MB
/cache=5MB
/data=287MB
So i changed my hboot by two methods (because i got problem so i tried to do it again with other method):
- first was via FastbootCommander v 1.51
- second via recovery FLASH HBOOT IMAGE etc.
after changing hboot i did full wipe, then partition align, then i install the rom (rom link here: http://www.cooldevs.com/archives/394).
When i got new installed rom and i check the free space, i got this results:
135 free and 252 used space.
What was wrong?
Here is a prtsc how look like partitions on my sd-card (Disk3 ~16GB):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}

Sometimes aligning breaks the partition. Also I think you may find the last line of my signature interesting given what i see in your screen shot

I forgot, i made partition with gparted which was booted from USB drive, MiniTool i use only for confirm how look like my SD-Card

How did you align? Gparted already aligns... further alignment breaks the partitioning
Sent from my HTC Desire using Tapatalk

i use Cool_alignment.zip, i shouldn't? well it is a new point of view... let me check
ps. it is good option to change hboot via recovery? i heard opinion the best way is via command line, but it works fine, also via recovery hmmm
UPDATE:
I changed hboot with recovery, after flash without alignment my desire stuck on the splashscreen... any sollution?
UDATE2:
Now rom works, but still have 135MB free and 151 used... strange... (i get jboot cm7 r2, then wipe all data, then flash the rom without alignment and still same)

Surely that is working then? The stock Desire only has about 137Mb free with nothing installed, yours is reporting 286Mb in total if I am not mistaken (add the two figures together).

Nooooo you really shouldn't. Gparted does everything you need, simply by pressing apply. Including alignment. That zip is for people who use cwm or ROM manger which uses SDparted with no alignment.
Even if everything works, I'd recommend deleting and retreating the partition in Gparted to undo the zip

Well something is wrong i think i should format my SDcard with GParted again and note here results. My friend has Desire too, so i will check it on both devices, last request: Anyone has
a hboot CM7? Because this rom for CM7. I downloaded from forum but it doesn't work (when i flash it i got error and failure)

Your post reminds me of simple facts, these being that numpties shouldn't be let loose on phones other than the old, basic Nokias.

This thread is about the cm7 custom hboot by Alpharev, not the cm7 Rom by cyanogen
Sent from my HTC Desire using Tapatalk

Bad news, i tried few times with other card and still don't know where is the problem i also check Data++ hboot, and after fresh and new instalation i got 252MB for Data but half of them are used (151MB used and 102 FREE it is little impossible on the fresh and new installation) (why?)
Any other suggestions? ideas? maybe this rom is little bugged? or i should format my SD card?
if i format again my SD card, what size i should set?
For FAT32 and for EXT4? (i got 16GB, 10class card) maybe my EXT4 partition is too big? about 1,51GB?
Best regards.

You can't see ext4 partition under normal system (system/application/manage apps) due to your sdcard is not mounted as /data. Your apps you installed are on sdext/app symlinked back to data/app you need to use 3rd party app to see free space on sdext... For more info look for a2sd+ and data+ script and see the difference
I recommend to use amarullz script, which is mounting sdext to as /data and real data (data partition on the phone) is used for sys app dalvik, u will be able to see your free space on ext 4 in the manage apps
Size of ext4 must be up to 2 gb for stability reason, hope this helps

Sorry for not fresh update but i got some good news.
When i reparted (this word is correct?) my SD-card again, and set EXT4 size lower, to 1GB size, this ROM (CoolSense 3D) with CM7r2 hboot work great.
Results, don't be greedy and use less space for APPSors!!!!
Best regards.
My config is:
SD-card (16GB class 10 - AData)
Fat32 - 14,5GB (created as Primary)
Ext4 - 1GB (created as Primary)
Good luck, for people which have the same issue

Insufficient storage..

Hey peeps.
I've run into a problem recently. I don't have enough storlage space left for installing apps from the market.
I'm using an ICS Rom by sandvold.com. I have partioned 2 gigabytes of my 32 gigs SD card to be used for a2sd and so far only 500 mb is in use. Both my dalvik cache and app data are on the sd card.
During the installation of a2sd in my Rom I chose to use the stock version.
Does anyone know a possible solution to my problem?
Ty in advance!

Open Terminal Emulator on your phone and type
Code:
su
a2sd install

I have done that already. How would I else be able to have my dalvik cache and app data on my sd card..?

If you want to know where all your free space has gone, try Diskusage app, and check your data partition...
Probably the cache of some of your apps has grown too much...
I had the same problem before I changed to Data++ hboot, and to COS ICS ROM (with dalvik2sd option)

I've just realized you can't install apps from the market...
Try clearing caches and/or data from your browsers. Or even games... When you have enough free space for installing, try Diskusage then...

I managed to clear up a little space by clearing my browser cache to install an app that easily clears my cache. I wanted to link my Titanium backup screenshot and the response to writing the command written above. Finally booted up my pc and here they are:

I had the same problem.I have a desire stock 2.2.2 rooted and the space is very limited.This is what i done:
I partition my sd card ext2/ext3 (ext4 doesn't work)
Installed link 2 sd (when you first launch you will be prompted what partition you have ext2/ext3/ext4)
Restart the phone and you are done.
After linking the apps( i mean i linked in first restart 40+) the phone will boot slowly but after that it will be faster.
Hope helps you

I thank you much for the reply, but this is already what I've done and I'm out of space again, with my SD partitioned. I partitioned 2 GB of storage on my SD and it isn't using it all as you see on the titanium backup screenshot. I have no clue on how to fix it..

I checked with the Diskusage app and found that approximately 600 MB was allocated for cache and data. Why isn't all of my 2 GB of sd-ext added to this "list"? Any suggestions would be apreciated.

Your output clearly shows A2SD is not working. Which means, Apps and Dalvik-Cache are not moved to SD-EXT.
So please run
Code:
a2sd install
After successfull reboot (script will you asking to do so after answering the question which data should be moved), please the output of this command again
Code:
ls -l /data

I ran the "a2sd install" command, moved dalvik and moved data by writing "y" to the questions.. After that I performed a reboot.
I then ran the command you wrote: ls -l /data.
I could be worth mentioning that during the installation of my ICS rom I choose to use the stock a2sd. I used to have a GB rom on my Desire some time ago. Back then I was using some other script called Darktremor and that worked. I have the opportunity to try another a2sd script during the installation of my rom. Any suggestions?

Ok this is what i suggest:
Remove the sim and memory card
If you have an card reader (backup your fat 32 partition and format it ;after that format ex2/ext3 partition)
Restore backup on the fat32 partition
Now do the phone a factory reset
Wait till it boots
Restart it
Put back the sd card and sim in the phone
Go to market and install link 2 sd and do the method i write in last post.
If this dosn't work flash data++ hboot from alpharev site

A2SD is still not working. How and with witch program did you partition your SD card?

MiniTool Partition Wizard Home Edition
Ok now i know what you are talking about:whatever you install it gives you inssuficient memory.I had the same prob after installing some app from market.I just installed it and it worked good then.

I used the recoverymode (Revolutionary) to partition my SD card, but it was an entirely new SD card at the time I installed it in my phone for about 1 month ago. I hadn't formatted it before I started using it.
I'm gonna try your method mansamihai, and get it done today hopefully. Not being able to install/update apps is driving me crazy.

do not use MiniTool Partition Wizard Home Edition for creating your ext partition.
while it may work for some, in lots of cases it can cause more problems.
backup your sd card to computer first, then try partitioning from scratch again.
gparted is recommended above anything else, or use 4ext recovery.

I used the partition function in the revolutionary recovery mode to partition my SD. I've made it to the point where I should choose which file system my SD cards partition is in the Link2SD app and I have no clue which one to choose? Any chance for a bit of help here?

I tried the to do it all over again, sadly without any change in results..
It is still not working..
Any suggestions on what to do now?
Thanks in advance!

[Q]EXT4 FS?

So I feel satisfied with Mimicry 1.5. So it is one more step for maximum performance: new file system.
I was searching for tut but there's too many results and I can't find anything, so I will post my dump questions here:
What is ext4? Is whole new FS on internal memory or extra partition on sdcard or both?
Will I need to reinstall rom?
Is ext4 console required or cwm will work too?
Can I restore nandroid backup over ext4?
Can i create ext4 partition on sdcard without reinstalling rom?
Sent from my HTC Vision using Tapatalk 2

Mimicry supports ext4 and I highly recommend using it. The easiest way to check and see what file system you are using across the different partitions of your phone is with 4ext recovery. I have a guide to switch to 4ext recovery here:
http://forum.xda-developers.com/showthread.php?p=33058659
It's like the 4th post or so, you can do it other ways as well but it just makes sense having the better recovery anyway. You are getting a few things jumbled together, 4ext is a recovery. Ext4 is a files system used in linux that is faster than ext3 but has potential issues with the extra journaling. Just do a little googling to find more info.
You can partition your sdcard to include a ext partition, usually used to store apps, it can be better for some and can be slower for others depending on many things such as how many apps you have, speed of sdcard, etc. Also som roms do not support an ext partition on your sdcard natively so that is something to keep in mind.
Do a little reaserch and decide what's best for you. But definetly get the 4ext recovery and I highly suggest changing all partitions on your phone to ext4

Okay. But after that how to format new file system both on sdcard and internal memory? Will titanium backup restore data of some backuped apps due to different location of ext4 partition on sdcard and so on. I mean i will give fresh start to my dz on sdcard too. But there's about 15 apps with important data that i need to restore easily after that.

umm, so if you choose to replace clockwork with 4ext recovery there is an option there to format all partitions (except sdcard) also under info, it will tell you current partitions in case you dont know
now there is an option to format sdcard in there as well (i recommend putting all contents of sd on computer first as a backup) choose swap partition size (probably just choose 0 but if you want swap look more into this) choose ext partition size (usually makes sense to have it larger than internal memory so in your case more than 1gb) dont do a second ext partition (dont know of a rom that supports it) remainder fat32
let it run and then transfer contents from pc back to card (this will transfer back onto fat32 partition)
any file need then is still accessible through both computer and phone (except windows cant read ext partitions)
in titanium backup you can choose where to restore apps too, and yes it recognizes apps on ext partitions

Finally I have time and format everything to start fresh&clean install from scratch.
I've taked screenshot of recovery

So I've noticed that phone keep writes in data, while sd-ext stays untouched. So how can I force install in sd-ext instead of internal memory? I've google it before start installing apps and found that I need to use terminal emulator for typing these cmds:
Su
A2sd install
But second one returns not found, so I decided that may be is automated process, but it isn't as became clear.
What should I do?
