[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.

Laggy Desire while opening apps

Hey,
I have extremely annoying issue on my Desire. Everytime I am opening an app there is a delay between tapping the icon and displaying app (full loaded screen of the app). Sometimes it takes 3-5 seconds. You can imagine how bothering it is. I found out that when I do full wipe it is great again but it takes less then two three days and lags are back. The biggest dealy has Handcent, Gallery, etc. Sometimes opening settings is laggy too.
Any idea how to get rid of this lags? I think it started some time after rooting my phone. Could be the problem the number of apps installed on a2sd storage? I have currently 106 apps.
I am really desperate! I love Android but this is not the user experinece I would expect from such a system and such a smartphone!!
I use GingerVillain 2.7 based on CM7. I used CM7 before and it was the same.

Do you use software like setcpu to control the cpu frequency or using scripts/software to control the voltage?

I used JuiceDefender but I had this problem before I use it. There is also some performance settings in CM7-settings. Do you think the problem is somewhere in CPU settings?

I don't think so. Given the fact that after a wipe it works fine, I'd put my money on your davlik cache. As it grows bigger in size, combined with probably low class sd card, it gets slower. You have some tips&tricks how to move davlik to /data in the development section. Or simply buy a faster sd card.

I have Kingston 16GB class4. I know that class4 is not the biggest number but I read that Kingston is as fast as some other cards class6 and that in fact it is not necessary to have so speed card This is a new want I don't really want to pay for another one...
Move dalvik to /data? Do you think this helps? And a2sd storage will work the same way?

Moving dalvik cache to internal /data partition often solves perfomance problems. That's why some developers do not move it to sd.
It won't disturb the working of a2sd, because has two different versions:
A2SD: All apps you install will be automatically moved to sd-ext
A2SD+: All apps you install plus dalvik cache will be automatically moved to sd-ext.
So when you move dalvik cache to /data, you are using "only" a2sd, but it's still working the same way.
But before this I would try wether wiping dalvik cache in recovery solves your problem.

Oh. Thanks! I will try! But I am afraid that I tried an app moving dalvik in the past and my phone got extremely laggy and buggy. Maybe it was not compatible app with my ROM
As I said when I do full wipe (so wiping dalvik as well) it is quick several days but then it gets back to laggy phone.

GV 2.7 - I have dalvik cache on Internal memory with Cm7r2 Hboot - no delays like you have, instead instant opening.
You can move it easily by using any terminal (I have better Terminal Emulator Pro).
Commands:
a2sd cachesd - moves Dalvik to SD
a2sd cachesdreset - moves Dalvik to SD, but firstly it wipes it.
a2sd nocache - moves Dalvik to Internal NAND.
a2sd nocachereset - moves Dalvik to Internal, but firstly it wipes it.
Personally, I prefer the "reset" commands.

Change your partition table. With aosp rom you waste almost 150mb on /system. That is one hefty davlik with 110 apps approximately.

Apps2sd

my ROM is a apps2sd ROM. Ext sd is reporting use, i.e. I set 1g of ext and storage says 658mb of ext is free. But in applications my apps give me the choice to Move to SD! ?
I used TB pro to batch move apps to SD but altho my apps now report they are on SD. Ext usage actually went down after the move. Am I confusing Apps on Sd / ext ? So on roms with default apps2sd you ignore in applications that they appear to be on internal mem?

Yes ignore it. You've just moved your apps from ext to fat. Read the root memory faq in my signature

I've some A2SD questions as well. I'm on CM7 with several apps already installed. My 4GB SD card has already been partitioned to 3GB FAT32 and 1GB ext4.
I was getting low memory warnings so I applied the darktremors script (stable, not nightly) expecting it to automatically move my apps to the sd card like your a2sd guide said it would. However, I still got low memory warning, so I manually moved the app to sd card using manage applications. This however moved the apps to the FAT32 partition, and several of my apps suh as my clock widget and swype no longer work.
How to I get my existing apps to move to the SD card's ext4 partition?

They need to all be moved to phone.
The apps should automatically move to ext download quick system info to check a2sd is working.
If its not try "a2sd reinstall" from terminal emulator.
Dalvik-cache is not moved by default and takes up a whole load of space so don't forget "a2sd cachesd" too
Sent from my HTC Desire using XDA App

OK, I thought the a2sd would move existing apps as well, didn't know I needed to "a2sd reinstall". Can I do the reinstall through an adb shell or do I need to download a terminal emulator?
I don't have a Class 4 card, it's a generic card and I don't know what class it is, so should I move the dalvik-cache to the cache partition using "a2sd cachepart" rather than "a2sd cachesd"?
Do I need to wipe cache and dalvik-cache before running any a2sd commands such as reinstall and cachesd/cachepart?
Lastly, do I need to reboot the phone after running these commands?
Thanks.

Ive never seen any performance issues even on class 2 cards. Keeping dalvik on NAND may give a miniscule performance increase, but I think its so negligible, you wont notice. But put it where you want. I recommend card though as you need the cache partition for downloads and as it fills with dalvik, it will limit the size of apps you can download from the market.
a2sd reinstall is for if it doesn't work properly. Its always the first thing to try. Then move dalvik. The way dalvik move works is that it wipes dalvik, moves the location then reboots the phone (rebuilding dalvik so expect delays when booting up the first time). For this reason its best to use "terminal emulator" from the market.
Hope this helps.

Alright, thanks! Will try reinstall and moving dalvik cache to the sdcard. Might get a new faster card since 4GB is getting tight anyway.

Tried the reinstall and it seemed to work. I had to move my apps back to the internal memory in 2 batches since I was running out of internal memory. So here's what I did
1. Move batch 1 of apps from sdcard back to internal memory
2. Run a2sd check in adb shell
3. Run a2sd reinstall in adb shell
4. After phone rebooted, checked my storage to find about 50MB of internal space left (woohoo!)
5. Move batch 2 of apps from sdcard back to internal memory
6. checked my storage to find still about 50MB of internal space left. I guess this means a2sd automatically moved them to the sd-ext partition?
When I ran a2sd check in step 2, the output showed that my ext partition type was ext2 rather than ext4 which I formatted the sd-ext partition to. Is this a mistake?
Will try moving dalvik-cache perhaps this weekend.
Are there any benchmarks I can run on the sdcard to make sure it's fast enough for dalvik-cache? Perhaps HDTach/CrystalDiskBench/ATTO/AS-SSD Bench/etc? There aren't any markings on the sdcard that indicates its class. It's a generic HP 4GB sdcard. Will a "dd if=largefile of=/dev/null" for read and a "dd if=largefile1 of=largefile2" for write work?

I've never known a card too slow for dalvik. Just move it. You can move it back again
Sent from my HTC Desire using XDA App

I believe the ext2 is due to some error with a2sd check. I encountered it too when i used the command and i was using an ext4 partition.
As for dalvik, try moving it. If it too slow then move it back.

Sorry, yes its a bug, fixed apparently in the latest BETA.

Don't think I'll be playing with the phone for a while - it's my wife's phone, and it took almost a week for me to figure things out and start from stock to CM7 with A2SD...now it's relatively stable with quite a bit of internal memory available, so I think I'll keep it that way for a while.
Thanks for all the help!

Hello rootsu,
i installed a Data++ rom and now some applications that i install, not from market, disappear after a reboot. From the market it is fine but if i put a .apk in the card and install it, disappear after reboot. Not all of them. Only some of them.
I have a aura sygic gps and this is one of them that disappear after install. The only way that doesn't is to move to the card. And another one, that doesn´te have the option to move to the card, disappear after reboot.
I already wipe dalvik cache, wipe everytnhig, rom install again, etc...
What's the problem? Do you now? I've searched a lot but i cant find anything.

That's a new one on me.
Install, take titanium backup, boot recovery, factory reset, format /data, titanium restore?
Sent from my HTC Desire using XDA App

Thanks, rootsu.
And when i go to install again, say that this will replace another application.
I already made a backup, when i have stock, and restore it and happens the same.
What to do?
Edit: I do a backup, only the application, with titanium, and when restore it and say error and dont restore the application.

Hello rootsu,
i modify de hboot to sense and all problems gone. Its good now. I think thats a problem with a Hboot Data++.
Thanks.

Ah maybe yes. Good work

Hello rootsu,
i install hboot sense and Leedroid 3.3.3 and works fine, but i have a question about cache file system. Why my cache system space is 202mb? In the AlphaRev 1.8 page the hboot sense as 40 mb. I dont understand.
The cache system space is from sdcard memory or memory phone?
Thanks

Although I am not rootSU, I feel free to answer:
I am pretty sure it uses space of SD Card. Using internal memory would be a little strange, especially we are talking about 160 MB here.

Stupid Link2SD problem

Hello Guys, i need help.
I followed this guide to create a Link2sd system.
http://www.xperiablog.net/2011/12/12/link2sd-guide-never-worry-about-internal-memory-limits-again/
Link2SD Partition is FAT32 primary, other one is also FAT32.
My problem is, after moving my apps i have a lot of free space in internal memory. After the reboot, which takes some time, some apps are missing, and i have no free space anymore in my internal memory. What am i doing wrong? I´ve wiped dalvik cache through CWM, but that didn´t help. However, I can restore old system through CWM Backup, but i want a system with working Link2sd.
Using .69 rom.
Any tips?

Okay, when it seems to be this problem then i´m using ext format. But ext4 can only be used with some kernels, doomlords one right?But i thought it´s some kind of dalvik cache problem. I read that some people on a german forum pointing of that. But anyways, i´ll try ext3, want to see if it works better.

Now i know what the issue was: You can link max.10 apps at once, than you need to restart phone. Guess that was the problem. I linked too much apps at once and dalvik cache had a problem with it. But thx anyways for responding.

Low memory at boot
I have an odd problem ,,, Upon boot my phone has very low internal memory and I get an error.
About 1 to 2 minutes after boot, all of a sudden I get a large chunk of it back ... is something corrupt in my LINK2SD setup ?
The internal memory is so low at boot sometimes that it starts to F/C apps and sometimes doesn't even load the SIM card ...

Lib, dex files ?
... it seems to be the linking of LIB & DEX files upon boot, if I turn the option off within LINK2SD the memory stays low, if I switch it on and reboot then after about 100 seconds the memory comes back ...
Does this mean I will always 'owe' back the internal memory from LINK2SD ?
I thought LINK2SD symlinked to the files, which to my understanding was just a small shortcut places on the internal pointing back to the EXT partition
When the memory drops low at boot, it makes things FC error

When I link the lib and apk files, Link2SD works grandly. Maybe it's the dex files that's causing issues? Or maybe you chose the wrong file system when you first ran Link2SD?

Desire on CM7 slowing down...

I ran my old desire for a year or so on the Supernova Rom, but got bored with the serious lag, It got better from time to time when I cleared the dalvik cache, and reformatted the SD card. But Igave up in the end, wiped everything, reformatted the card again, and loaded Cyanogenmod 7.
It was a revelation.Everything was really snappy, and the Desire was like a new phone again.
But the troubles are returning. I started getting some lag opening apps a week or so ago, and now I am starting to get forced closures too, and the lag is getting worse.
What's going on? Is there anything I can do to stop this from happening?

Don't bother wiping dalvik, it simply rebuilds afterwards which is why it takes so long to boot...
Are you using the ROM with an sd partition, how did you create it? Any particular A2SD script?
Max 2GB ext4 partition should be done using gparted or 4EXT recovery only, not clockworkmod or minitool partition wizard.
(Remember also that your hardware is starting to age, and there are limits / apps which the Desire was never designed to handle)

Yes, Iam using an SD partition created with gparted - my laptop runs Linux. I am using S2E.
What's puzzling me is that it ran really fast and snappy to start with, but is now slowing down again. I am getting regular timeouts -but if I choose "wait" its usually OK. But sometimes I get a forcedclose. I don't want to have to keep reinstalling the ROM to keep it fresh!

So the partition is made correctly, which is good :good:
Check your S2E settings, what have you moved to the partition?
It works best if you only move apps and dalvik cache to sd-ext. You should keep app data (e.g. saved gaems and app preferences) on your actual internal memory for speed and stability.
You should also be s-off and on cm7r2 hboot to maximise your internal memory if you have many apps. This will work best with the above, and applies regardless of your A2SD setup.
If S2E is already set to move apps and dalvik only, not sure what else it could be. Any other 'tweaks' / scripts / memory managers / task killers which can do more harm than good? Does it happen with any particular app?

Thanks.
Sorry to be so long to reply. Had to take some time out as I snapped the tendon that operates my left thumb. Yes,really.
Anyway. The problem - which is getting worse - may be that I have application data on the SD partition.And S2E won't let me change it - greyed out. Why would that be?

Well at least we're narrowing down the issue. I believe app data on sd-ext is almost certainly the cause of slowdowns. It works much better when stored on your actual internal memory, as nand flash is faster than your sdcard.
No idea why it won't let you change it back, I've never used it myself. I've looked at the Play Store first screenshot. Should be a case of unticking, and rebooting. Do you remember when you first configured it? Did you tick everything?
You may not be able to move it back to internal if you are on stock hboot and you have more than 150MB of app data. i.e. there's not enough free space to move it back?
It may be a case of full wiping and starting from scratch:
- Titanium backup of all apps
- Flash cm7r2 hboot using fastboot
- Full wipe, flash ROM
- Install and configure S2E
- (If above doesn't work, use another app like Darktremor A2SD, tick apps and dalvik only)
- Reboot
- Restore apps
- Check all your partitions using an app like DiskUsage. You should have much less free wasted space on /system, 287MB internal memory (/data) filling up with app data, and your sd-ext filling up with apps and dalvik.
Take it easy with the thumb!
