[Q] any rom with data2ext

Hi all,
I want any sense rom with data2ext because then i got many MB free for apps.
How do i do this and is the speed acceptable?
Thank you!
Nick

easy:
1. root(if you havent already)
2. format sd-card with ext partition(like with a2sd but mybe a bit bigger partition)
3. install any rom with data2sd installed
and from my experience, no the speed is not acceptable. You will be much better off using a2sd+ which also gives you plenty of space..

yeah ok.
but i want many apps installed.. likely big games. and some games MUST be installed to the phone.. so with 10 apps my phone is fully full.
i always got like ~130mb internal.
but i want data2sd cause then you got many many mb free for apps.
+ when i installs an app and move it to my sd ext. it still leaves something on my internal memory wich takes space. so apps2sd still takes quite much space on internal memory.
so you all got this problem?

You are not understanding the difference between a2sd and froyo apps 2 sd. The last one being the one, where you can move apps freely.
The oldstyle a2sd+ moves both apps and dalvik cache to ext, so even though it says you have only gotten 130 mb, it will fill up very slowly. I myself have around 100+ apps installed including google earth and some games, and i have no problem..
edit: and no you cant move apps to ext. The app2sd in froyo is moving them to a special folder on the fat32 partition, while the oldstyle a2sd+ have the /data/app and /data/dalvik symlinked to the ext-partition, so apps will always be installed to ext using this method.

ok so i took leedroid.
and posted this in his thread:
hi all,
i got the apps2sd version.
and i got ext3 876MB.
But at the first page it says: lots of free internal memory! on the apps2sd version.
but i only got 133 mb internal mb free.
So i dont think thats much?
cause my apps cant move to sd.
some can but not all games.
so my space is limited and i really need much internal memory!!!
please someone help me!
Greetings,
Nick
EDIT: and how can i check if my apps and dalvik cache are thruly on my sdext?

OMG!
Please read my post over again.....
a2sd works by symlinking some folders to your sd-ext partition. This will NOT mean that your system will measure plenty of space. Just that those 2-3 folders will not take up space on the /data partition, so installing apps only leaves a little bit of data and thus only decreases the free space a tiny bit. 2 see this better try installing "quick system info" which will let you see how much of the sd-ext partition is used. Then go install a lot of apps and see, if this fills your phone. It should not(only a2sd storage in quick system info should be filling up).
and to check, if they are there, install an app like root explorer and check /system/sd which should show the folders present on the sd-ext partition("app","app-private" and "dalvik-cache")

Are you using a2sd+ at all or are you manually moving apps to SD via application manager?
data2ext still has not matured enough with relatively high risk of data loss atm. I have no doubt the devs are working hard on it, but it is not ready yet to go mainstream. AuraXTsense sported data2ext in 8.1., yet it has returned to good ol' a2sd. It simply is not stable enough.

[Q] Memory and Ram Issue on InsertCoin CM7 HBOOT/STOCK 1.1.1

I recently installed InsertCoin's CM7 HBOOT/STOCK 1.1.1, after installing my internal memory has become really low and i only get 120mb of ram when i got 220mb on the official 2.2. I have partitioned my sd card using gparted. I made a normal fat32 and a EXT4. Do i need to make a EXT3 partition? also how would i know if the apps are on my sd card since i cannot move them manually with application manager. Please can you help me. Thanks

If u wanna know if ur apps goes to ur ext4 in ur sd card
Go to market search quick sysktem info pro

Hope iam usefull

do i have to move the apps to the sd card with the application manager because after installing less than 15 apps i get low memory notifications, i had like 40kb internal memory. Using the System Info app i can see that my ext4/a2sd is being used.

how would i move the dalvik cache. Also if i use the A2SD+ version of the rom, would i install it exactly the same as CM7 or would i have to do something different pre or post install?

SOLVED!!!!
i flashed the CM7r2 hboot from alpharev.nl by downloading the hboot, naming it PB99IMG.zip and using clockwork recovery to update the hboot. then i installed Insertcoins 1.1.2 rom.

[Qext4 partition problem

hi everyone,
i just rooted and installed the Cyanogen 7.2.0.1-bravo rom and partitionned my sdcard 16gb to a FAT32 partion and ext4 partition with 1gb.
the problem is the intern memory !! ( lack of space ), idk if i missed something or didn't installed a script ... i have app2sd already installed and i moved the most of the apps to my sdcard but the ext4 partion is not used and can't see it .
so what do i have to do ?
ps: i just istalled a2sdFroyo, but doesn't help or i didn't used it right ...
pls help

when you say "i have app2sd already installed" how have you done it?
how did you partition your sd card, should be done with gparted or 4ext recovery only. if you used something else, backup your sd and repartition.
to maximise space, s-off and change hboot to cm7r2, recommend guides here (read them slowly and several times to help your understanding)
then full wipe, install rom.zip again from scratch
to enable the A2SD, one method is to install an app like S2E which can move apps automatically to sd-ext, no need to 'move to sd'. you can keep dalvik cache on internal, and move it to sd-ext if you still run out of space. internal memory will always go down as stuff builds up on internal (data partition)
whatever rom you use, install an app like 'diskusage' to browse all your partitions in future, that way you can actually see where and how your space is being used

i followed the MiniTool Partition tuto to make partitions and then i installed normaly app2sd
why do i have to reistall the rom again ?

do not use minitool, this may be the reason why you cannot use the partition at all.
backup your sd card to pc first, then use gparted, there's a video guide from the link i posted
(make sure you have a nandroid backup, titanium backup of apps and backup contacts to google)
i am advising a full wipe because i don't know how you "installed normally app2sd". if you reinstall the rom from scratch without anything else, there is less chance of things going wrong. using S2E afterwards is easy.
if you want to set up this rom or any rom properly so you don't run out of space, you should understand where all your apks, data and dalvik are stored, and what the different hboot partition tables are. it's all in the guides i linked.

i installed app2sd after i finished with the rom and the partitioning of the sdcard, and it works without any problem
i istalled now S2E and i transfered the apps to the ext folder now i have 140Mb free space and i think it's working now becuase i sync with skype and facebook and i still have the same space in my internal memory ...
what do you think ?

if you install something like 'diskusage' you can KNOW if it is working...
i would still recommend s-off and change hboot to cm7r2. this will use space more efficiently, and you can install many more apps. just read the guides i linked. you can still learn a lot more

Hi. I think its working, from 1Gb i still have 700 Gb in green color.

write down your free sd-ext space then install an app from the play store. Check the space again. If it had gone down your sorted.

looks like it is working
with diskusage you can just zoom in on all your partitions including sd-ext, so if you see your app apk's there the script is working.
open diskusage again and select /system. i'm willing to bet that you're still on stock hboot. you will see a lot of free space on system partition, which is useless...
therefore still recommend (for the last time) to s-off and change to cm7r2 hboot. you seem to keep ignoring this and the guides...

[Q] The best method to to get space with desire?

Hello Folks,
Now a days we have a lot of methods to fix space lack in desire phone.
Which one is the best for you?
AD2SD?
INT2SD?
APP2SD?
LINK2SD?
Any other?

Whatever the ROM uses. They all do basically the same thing - move stuff to your Ext partition to free space on phone.

except INT2SD, it converts ur ext partition into internal memory (data partition, so yh pretty much the same) but only a few roms have it

I choice RunnyMod 7.02 thats came with INT2SD and AD2SDX, but both of them i'm not able to use it.
I hv CM7r2 HBOOT and it is recognized in Amarullz setup, also, i hv a 3GB SD Ext4 partition.
The main problem is, the script setup says that my device does not support both of them.
So, my question is, if INT2SD is better than others, I'll try to fix this, but if is pretty much the same, I wont try.
And the last not least, I cant post in dev forum, so cant explain my problem there!!!
Thanks

You dont need 3gb ext4 partition. Make it 1 gb, it is more than sufficient.
I have used APPS2SD and INT2SD both. But i like INT2SD more as it doesn't slow down my memory card and it allows me to install more apps.:fingers-crossed:

Int2sd the best, cause all other methods lacks of memory after ~100 apps installed.

i felt that a2sd was faster than int2sd. it might be because i have a slow sd card. a2sd can be set to leave some parts on the internal memory keeping those parts faster

From what I understand (and while not very new to this, I am not an expert or a developer) there are three partitions that are restricted inside the internal ROM: apps, data, cache
People seem to agree that moving data to sd slows down the phone, so they tend to keep it in the internal memory. So the main difference between the scripts is if the move the data to sd or not. I think with most modern ones, this is an option and can be enabled or disabled.
As others said, int2sd or int2ext follows a different approach, but I think the principles and end result are the same.
I like the roms that apart from installing the script that runs at startup, they provide the control script that you can run from the terminal and check the status or enable/disable features after installing it.

Moving dalvik cache to sd slows the phone down, everything else can be moved.
I prefer a2sd.

Depends on ROM, mostly
Most ROM devs already indicate a perference for a2sd scripts. If I recall correctly, the first AOKP builds needed m2sd, PA prefers INT2EXT and most GB ROMs used a2sd.
As for speed, try to keep app data on internal memory. Anything else can be moved. Dalvik-cache is mostly taking up half of the internal memory, so an excellent candidate to move.

[Q] Desire, roms and ext*

Hi guys..
Hope someone will be so nice to help me..
So..I have this desire and it was running with the supernova rom. Problem is it gives me a annoying issue that i didn't manage to solve...not even reset it nor reflashing the rom. It always comes out again..
I decided to try some other roms...and in the last few days i flashed so many, but i never managed to make one to see the ext* partition...at second boot it always shows only some MB as internal memory.. I tried to do it on any way...formatting sd withing the recovery, from pc, flashing alignment..nothing..
Now i'm asking...do i have to have or to do anything special before flashing one of those roms? Why the supernova works with no problem and all the other never?
Thank you in advance

How did u partition ur sdcard?
Use this guide
http://forum.xda-developers.com/showthread.php?t=2125513

You should partition your sd card as above, no alignment or anything needed as gparted or 4EXT make properly aligned partitions.
Depending on the ROM, you may still not 'see' the ext partition i.e. you won't see "internal + ext" as your reported internal memory like supernova, but your apps still go to sd-ext. Most of the time you just have to keep your apps on internal (i.e. don't 'move to SD'), which tricks the apps to sd-ext.
Some roms require you activate A2SD via terminal commands, others have built in scripts, see each rom thread for details. Make sure you're also on the right hboot (requires s-off) to maximise actual internal memory /data).
A good way to check is to use an app like 'Diskusage' to browse all your partitions. As long as you're sd-ext is filling up, it's working

Ok. Now let me explain what happens.
Supernova has a script that moves data/data to sd-ext. Data/data is the folder that occupies most of the data partition. It's the application data itself.
The other ROMs leave data/data on the internal memory, for performance reasons, and move other stuffs, like data/app, or dalvik cache to sd-ext.
You have many apps, so only moving dalvik cache and data/app isn't enough. You should be using ROMs that use INT2EXT or INT2SD scripts, like this one:
http://forum.xda-developers.com/showthread.php?t=1315961URL
Or, use the INT2EXT4 script from here:

So you partitioned using 4EXT or gparted? (NOT minitool or clockworkmod recovery as recommended?) If not then backup your sd card and repartition, so we know that it's definitely properly done.
Before you reinstall all your apps in one go, just restore or install one. Then like I said, install 'Diskusage' as well, and try to find where this app has been installed to. If it's on sd-ext, then it's working, and if it's on /data, then it's not.
Depending on the ROM, some stuff will still get stored on the /data (internal memory) partition. So there is always an upper limit to how many apps you can install. Most of the time, app data gets saved on internal. Sometimes dalvik-cache also gets stored there, but you may be able to move it to ext.
Regardless of which ROM or A2SD method or other script, the first step is to work out and understand what is being stored where, hence why I keep recommending 'Diskusage'
Also you are still on stock hboot, which has a very low /data (internal memory) partition, only 147MB. Some ROMs are better on other hboots before you flash them as they have a smaller /system size, and thus a larger /data partition. For instance, many ROMs fit on cm7r2 hboot, with a larger 287MB /data partition which fills up a lot slower. If you decide on a ROM, all of them should say which hboot is best for it, you should download them from alpharev.nl, and flash them via fastboot, guide here.

Thank you guys...so much.. SItuation is more clear now...
So..if i use that Rom with INT2EXT it should work like supernova and it would use the exp partition instead of the data partition..and it could be ok... I got performances would be worse, but again...i was already running a rom with same script..and it was ok... Would i get again that issue about cell reloading the system now and then...or it's caused by the system using the sd instead of the internal memory as data partition?
Again...i think ext partition is ok...i tried to check it...and...the system uses it.. THe problem is that with so many apps...internal memory gets full anyway...so..i have to find another solution...
I checked..and i always read that it was ok with stock hboot....i'm not such an expert...but since i never touched it..i thought it was stock... As i told, i rooted it..and turn it s-off...
I know the bad things about this cell is the low memory space, i just wanted to use it 'cause for the rest isn't bad...and even changing the internal partition...will make it better...but...dunno if it will worth the...risk..?? I
I will think about it.. Guess i can even give up on some apps...and put there only the apps i really need...it won't be a problem...
Thanks again to both

Glad it's starting to make sense. Yes that script should work for a lot of apps. Don't know about the "reloading system" issue, but your main goal is space for apps.

It's always best if it is created using gparted or 4EXT recovery, they are the recommended methods by far.

Yes, you are still on stock hboot. Once you understand why you may want to change hboot, it's worth the small 'risk', because that way you do actually get more internal memory . I believe on some of the ROMs you tried you simply ran out of memory faster because you didn't change hboot.
As for which hboot you use, it is entirely dependent on the ROM, you have to search this yourself. I would recommend a ROM with at least cm7r2 hboot, and a int2ext script if possible.
(And I'll keep recommend installing 'diskusage' until you try it and understand how and where all your memory is used)

Just to let you know i managed to change the hboot with proper one...partitioned the sd again via 4ext recovery..installed the right rom and it shows me the ext4 partiiom as internal memory..
Now just have to test it and see if i will get the same problem i was having with supernova, and if it works properly..
Thank you so much to both for the help...really appreciated...
