More space on CM7: App2SD+, Partition tables etc. - Desire Q&A, Help & Troubleshooting

Hi -
I'm getting ready to install CM7 onto my phone, but I'm needing some guidance on getting more storage space out of it. I was going to opt for the App2SD_+ script, but reading through the forums, a lot of people seem to be recommending S-Off'ing the device and installing CM7 partition tables? How is this better? What are the steps? What does S-Off allow you to do that App2SD doesn't. Is this safe and fully tested?
Thanks.

With CM7 Layout you will have plenty of space for apps in internal storage (300mbs aprox). Using this layout all your apps will run in internal storage which in theory is faster than your SD Card, getting more perfomance. However with this layout you can't flash radios using recovery due to a small cache partition, and some ROM's will not fit in new layout, beacuse you will only have 130mb for System.
If you want to do it, go to http://alpharev.nl. It's fully tested and safe. The only risky part is flashing new HBOOT when you S-OFF.

So if I understood correctly, using CM7 partition tables simply gives you more space on your internal memory (as opposed to making the system think a segment of the SD card is 'internal memory'), and by such, the apps you install on your phone are faster, and the method is overall more safer (less likelihood of corrupting SD card etc.)
What if I wanted to have more than 300mb of internal storage to install apps (say 1 GB)? is App2Sd the best method for me?

So my question would be if there is a way to get app2sd+ (or app2sdext) working on CM7?

Yes, check Cyanogen Mod post At the bottom of first post.
Also, you can flash Darktremor A2SD afterflashing CM7 (without boot). After first boot, use connectBot, terminal emulator or simply ADB shell, a type
Code:
a2sd reinstall

Glad i found this post as i was just asking this in another forum. I'm using the stable CM7 and was looking for the best option between:
S2E for CM7 (easy to use)
Darktremors Script (used it on Gingervillain and pretty easy to use)
Custom MTD Partitions (as per your post, also heard it's faster and more stable)
Still researching but any opinions would be appreciated.

CyanogenMod7 gives 302MB of internal memory after clean install.

[Q] Pros and Cons of sd-ext?

Hi!
Just would like to know the pros and cons of formatting into ext4 on my SD.
As far as I can find :
Pros : Supports files larger than 4GB as Fat32 cannot
That's about it I think...
Cons : Windows cannot natively detect such a partition
Why I ask this is I just saw a this post

You're mixing things up here a bit I think. Sd-ext referrs to having a partition on your sdcard to allow support for Apps2SD (basically being able to move apps to your SD card and run them from there in order to free up space); you'd basically repartition the card so that there's an ext3/4 partition for apps and a FAT32 partition for data.
As for the ext4 filesystem, it does allow for larger file sizes and is also a bit faster but you're correct in the fact that you won't be able to natively mount it on a Windows system.

But don't we already have Apps2SD in GB, + all the apps that do it for you. How is this different, apart from some apps that can't natively be moved? And why is it faster? Internal memory should always load faster, should it not?

GB has the ability to do Apps2SD but it requires the partitioning as, I believe, a symlink is set up so that partition on the sdcard acts as a part of the devices internal storage.
As for speed, just moving apps to your sdcard won't speed up your phone; what that poster you quoted was talking about (most likely, I'd have to see the original thread) was converting your devices partitions (/system, /data, /cache, etc.) from ext3 to ext4. ext4 is a bit faster however some ROMs do not fully support it.
Sent from my T-Mobile G2 using XDA App
Ok, let's clear this up. GB has Apps2FAT32 (a2sd) natively. A2EXT is completely different but none of that is the point of the OP's question.
When it comes to our phones - there is almost no notable performance gain when using EXT4 over any other EXT format. Our phones don't utilize FAT32 internally - just on the sdcard. EXT4 is designed for use with massive file systems. A couple Gigs really doesn't access it's full potential.
While the question is interesting, I'm not really sure what you're planning on doing. Don't format your sdcard entirely in EXT format, and don't attempt to format your phones partitions as FAT32. The result would be... just don't do it.
Just read this on the portal
http://www.xda-developers.com/andro...hd2-data-successfully-moved-to-ext-partition/
This has two main advantages: larger sized data partition and more speed as EXT is inherently faster for I/O purposes.

How do I go about formatting a section of my SD into ext4, with existing SD data intact.
And how do I move apps that area already in my phone's internal memory to the ext4 partition? I know there's an option in ROM Manager and CWM, but just don't want to mess anything up

As far as I know, only two ROMs actually support the real A2SD: PyroMod and MexDroid. It's recommended you format the EXT partition to EXT4 before you actually flash either of those ROMs, and you have to rename MexDroid in order to get A2SD working.

Thankfully I am already using meXdroid~ Guess I'll just wait for the new version in the next few days to do the formatting. Can I backup all my apps with Titanium Backup, flash ROM (wipe data/cache and dalvik cache), restore with Titanium.
Or would I have to reinstall every app again so that it goes into the ext4 partition?

There's a script to accomplish this on pretty much any ROM. It *should* work on current ROMs too. It's called 'darktremor a2sd'. Still find it amazing people forget about that one when this question comes up because it's one oldest methods of obtaining a2sd.
I'm still not understanding the OP's question. Are you wanting to do this for an IO performance gain or for space? I can understand doing it for space if you have a ton of apps but if you're doing it for performance it's a waste of your time. You're internal partitions should already be in EXT4 format (use 4EXT Recovery if they're not).

I'm doing it for the performance. Have been using 4EXT for a few days and loving it. Already converted internal memory to ext4 from ext3. If further partitioning my SD card for performance is really not noticeable, then I guess I've got nothing to worry about

you need to partition your sd-card with an EXT3 or EXT4 partition besides your fat32
yeah, i already did that. what now?
It should simply work.
Can you check it in titanium or so?
heh, it dont work. do i need to install terminal emulator or something and insert some codes?
i'm no expert in this but I mostly check space usage in Titanium Backup.
It's in the market

when you say it doesn't work, what does titanium output say when you open it?
if it lists a2sd storage, and free space is less than total, then A2SD is working just fine as it should and already applied. no need for extra commands. keep apps on 'internal', don't manually 'move to sd', and they will continue to use the partition.
i find 'diskusage' a really good app to show how each partition is being used.
one other thing to check, are you s-off with cm7r2 hboot? this will give you a lot more space.
if you upgrade to a more recent version of the ROM, apps and dalvik cache are stored on the ext partition by default, thus giving you even more space. if you want to stick with your current version, there should be zips posted in the thread to move dalvik to sd as well.
The easiest thing to do is installing "s2e" from Google Play Store. Search the tread for more info.
If that's not enough, you should considering flashing "data2sd" - it gives you almost unlimited storage on your phone (google it ) I do think it's supported on your rom... not 100 % sure

[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 have not enough space

Hi everybody!
I've a Desire with stock rom 2.3 (and no root yet) and it worked fine until last week.
If I try to install a new app I receive an error about free memory space. I've already try to move all apps to sd but nothing, I can't install anything.
I've try also to do an hard reset and fully wipe/factory reset (from recovery) and for a while it seems to works, but if I install some apps the problem come back.
Why? What can I do?
A friend suggest that maybe there are some directory in filesystem from older app (now unistalled) and, since I haven't root permession, I can't remove them. With root permission can I fix it?
Thanks!
I flashed a custom rom on my desire which used the sd card as internal storage. Problem solved.
Verstuurd van mijn GT-I9505 met Tapatalk
Read this guide to s-off, and install a custom recovery
Use this guide to create a 1gb ext4 partition on your sd card. No swap.
Download a custom rom from the htc desire dev section and flash it. I would recommend milwilds redux rom. It will automatically install apps to the parittion and you will have space.
thanks for reply!
I'd like to fix this problem without flash new rom, eventually with root only. It's possible?
When I bought this there was space enough, why now I haven't? Factory reset does not erase all partition and sistems directories?
Thanks!
Also, before you flash the Rom, best to flash recommended hboot if necessary, read the first post or search each thread.
This way you use your internal memory more efficiently.

Factory reset only deletes user data.
When you bought it, you didn't have apps installed, and probably apps were smaller back then.
What are you trying to say? That you want to flash a stock rooted ROM?

Nope.
All my apps were installed somewhere in filesystem (maybe in /system?). My question is: when I do a factory reset, what I'm going to erase? Only user data in user directories, or all content of every system directory? (of course, not system files).
I'm only trying to understand why when I bought the phone I've a "lot" of space for my app and now, after a factory reset, I've not enough free space to install more then 2/3.
Example: I wipe/fr, reboot and config the phone; then I try to install Ruzzle (16Mb),Whatsapp (9Mb) and FB(18Mb). Now if I try to install any other apps I get the alert message of free space. Same error if I try to record a video or take a photo.
I think there is something wrong..
I hope that you can read and understand what I'm writing, my english is a little rusty

A factory reset will wipe /data, dalvik cache and /cache.
When did you buy your phone? I remember that, when I first bought my Desire, facebook was only 8mbin size, and moved to sd, it only took 2 mb of internal memory. Plus, large apps require large dalvik cache. That's why your memory gets filled so easily.
You can resolve easily and keeping your stock ROM (but you'll need a FAST microSD card, my 32GB is class 10):
1) Root and s-off your device
2) Format your microSD with an EXT2, EXT3 or EXT4 partition of 1GB, then the rest as FAT32 (you can do it directly from phone using the 4ext recovery, or you can format the card from PC using a tool for partitioning which supports linux formats... I don't know if I can mention names in this thread).
3) Install INT2EXT or INT2EXT+ from recovery.
4) You'll have 1GB internal memory with no out-of-space problems.
That's all
Stock kernel doesn't support ext4 nor ext3, use only ext2 if u want to keep it.
Anyway, I believe that supernova ROM would be a much better option, it's basically stock GB made by HTC with some tweaks and script for more space.
Thanks for replies!
I still do not understand why I've no memory for apps after a factory reset; if I wipe all data, I restore all space, like when I bought the phone. Ok, apps are bigger than 2 years ago, but not so bigger that with 3 apps I occupy all space!
Anyway I'm considering to upgrade to a newer version; if I must give root permission, install tools, repartition sdcard and so on, I might as well to flash a newer version.
Curiosity: are there filesystem directories that are not intrested from a wipe? Differently, which directories will not wiped during a factory reset?
Thank you very much!

yes what your seeing is caused by the apps being a lot bigger now. Facebook is a lot bigger.
And its impossible for your apps to be going to system. You'll have to root and use a2sd

You need a rom with an a2sd script, regardless of it being GB, ICS or JB.
Good, I will search in subforum for a new rom.
Maybe it's a bit OT, but JB rom are stable enough for daily use? Can you suggest me a JB rom with a2sd script? (or even ICS, if JB is not stable enough).
Thank you!
I use jb as a daily driver. The ROM in my sig is the most stable jb ROM I've tried. It has very few soft reboots and has decent speed. It also has a2sd. (Activated through terminal after flashing rom)
However if you really need stability, speed and reliability I would highly recommend using gingerbread. Mildwilds ROMs are great and most of them have an a2sd script as well, which is automatically activated. Try the one based on redux.

I have a similar problem to this. I own a HTC Desire that is rooted, with Clockworkmod recovery environment, and I got it running Cyanogen mod 7.2.0.1.
So I was reading around this problem, and there are several solutions. It seems the most foolproof way is to format your SD card and partition it so that you have an EXT3 partition, and a FAT32 partition as has already been suggested here.. This way you can use an app to fool your phone into thinking that it has the EXT3 partition of the SD card to use for internal storage as well as the 150MB of internal storage it comes with. I had an 8GB SD card so I did a split of 2GB for the EXT3 partition, and 6GB for storage of music, photos, etc. etc. I followed this handy guide to do it, and it worked a treat: (sorry, have been unable to post an external link as I'm a new user.. maybe I can post this later).
When I rebooted my phone, sure enough, it showed 2GB+ of internal storage, and I can install all the apps I want. However, I'm experiencing apps hanging and crashing all the time, and I know it was caused by this most recent change. Prior to this, Cyanogenmod was running just fine! I've read a bit more into since doing this, and a lot of people reckon you shouldn't use more than a 512MB SD card partition, as anything over this causes performance issues. Others disagree, and think that anything 2GB or below should be fine. Presumably the apps hanging/crashing is because there is fragmentation of data between the SD card EXT3 partition and the actual 150MB internal storage.
It's frustrating, as other than this the phone is still a very decent handset despite it's age... it's really the storage letting it down. Before I try factory resetting (again!) and going back and trying a 512MB partition, (or just going back to having only 2 apps installed!), has any one else had experience of this?
Any help very much appreciated.

I had an 8GB SD card so I did a split of 2GB for the EXT3 partition, and 6GB for storage of music, photos, etc. etc. I followed this handy guide to do it, and it worked a treat: (sorry, have been unable to post an external link as I'm a new user.. maybe I can post this later).
When I rebooted my phone, sure enough, it showed 2GB+ of internal storage, and I can install all the apps I want. However, I'm experiencing apps hanging and crashing all the time, and I know it was caused by this most recent change. Prior to this, Cyanogenmod was running just fine! I've read a bit more into since doing this, and a lot of people reckon you shouldn't use more than a 512MB SD card partition, as anything over this causes performance issues. Others disagree, and think that anything 2GB or below should be fine. Presumably the apps hanging/crashing is because there is fragmentation of data between the SD card EXT3 partition and the actual 150MB internal storage.
It's frustrating, as other than this the phone is still a very decent handset despite it's age... it's really the storage letting it down. Before I try factory resetting (again!) and going back and trying a 512MB partition, (or just going back to having only 2 apps installed!), has any one else had experience of this?
Any help very much appreciated.

well,I don't use gingerbread anymore.but I can say that you can't experience a good performance to use both internal and external (sd-ext) partitions to use and install your apps. better choice is to use one of them.use default a2sd of rom,or use another script to install apps only in sd-ext partition. I have used and tested a lot of roms (GB-ICS-JB) and I can say in my experiences, that you don't have problem to use an sd-ext partition with about 1.5 - 2 gb size.you can see the recommendation of devs in first post of topics, and they tell us what is the minimum-maximum size for the best performance. sorry,i can't search and give you the links,but I just had a really good smoothness and speed with some scripts that you can try them: like mounts2sd, ad2sdx,... you can find link of them with search. and you can use cm7 int2sd version...but it has a bigger size than normal cm7. here is this topic : http://forum.xda-developers.com/showthread.php?t=1357257
@kmanpilkers
Which guide did you use to partition, should be done with gparted or 4ext recovery.
-Ext4 should also be slightly faster than ext3.
-Anything up to 2gb is sufficient. Don't know where you read about limiting it to 512mb. The whole idea is to be able to install more apps on the partition, 512mb will fill up a lot quicker than 2gb...
-you can use space more efficiently by s-off and changing hboot, so you have more than 150 MB of internal. You are currently on stock hboot and have a lot of free wasted space on your /system partition
-depending on your Rom, stick with a single a2sd script, it may be built in or need to be activated, read the Rom thread. Then let it do it's job to move apps to the partition

Read this guide to s-off, and install a custom recovery
Use this guide to create a 1gb ext4 partition on your sd card. No swap.
Download a custom rom from the htc desire dev section and flash it. I would recommend milwilds redux rom. It will automatically install apps to the parittion and you will have space.

[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

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

I tried every possible way...as i told.. From recovery and from pc...
Titanium backup actually sees the ext partition...but..when i install the app...after a while internal memory gets full...so..
I don't know...i'm..disappointed and frustrated... Don't get why only tha supernova works as it should without any problem...

Thank you..i will try...
Again..just tried with another one...and...as much as i put back my apps...internal memory gets full...
I don't know what rom is the right one..too many..and too complicated chosing the right one...
I just wish i could have sense and the working ext partition...
Cell is rooted and s-off... Hboot..dunno....it says 0.93.001
Thanks for the answers..

Yeap...last time i tried to put back apps from titanium backup it told 81...i wasn't putting back them all..but surely more than 50

Cool3d, LeeDrOiD, and so many other i don't remember...
Just tried RunnymedeMod...seems that it uses the ext partition...but...i get the low memory space warning anyway...it's..useless...
THe only one wichi works for me is supernova..

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
Really appreciated

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...
