[Q] Abit Of Help Please...

Am using Leedroid App2SD+ ROM and have 1gb ext with 756MB free, i have lots of apps installed but now my phone is showing low memory 15MB, so I have moved alot of the apps to SD card to try free up abit, but its not freeing up phone memory its still staying at 15MB.
Why wont all apps just use the ext? how do I get free phone memory back up again.
All help welcome thanks

All apps have to use internal /data/data folder to store libraries etc. So if you need more storage read about data2sd.

Because if you have A2SD+, then Move to SD in the application manager has no effect (apps are already on the SD Card).
Try running a cache cleaner, maybe too much cache. Possibly a2sd+ is not working properly?
I never had that much low space on LeeDroid when I was using it (had 55 apps of my own installed).

check the leedroid topic?
I read something about a memoryleak in flash what could cause the problem.

You can also move dalvik-cache to sd to free about 40MB internal memory.
Simply download terminal emulator from market, and then put su and a2sd cachesd or cachesdreset (it removes old dalvik cache from internal memory) commands.

Oh yeah it does. It ruins everything you were supposed to get with a2sd+.

Read better next time. It was regarding random access memory and not the internal storage memory.

Thanks guys for reply's.
I have no cache to clear, so it has to be data, what the best way on doing datatoSD?
I thought the rom has to support it, can I just install somethink to make this happen.
thanks again

Here you have zip instalation scripts and some tutorial how to manage that:
http://forum.xda-developers.com/showpost.php?p=10692249&postcount=1299
Remember that you will lost your apps! Backup them by Titanium Backup (I don't think that backup and recovery by nandroid it is best solution if you are messing with symlinks and /data partition).

I never had any issues like yours when I used Lee droid A2SD and had installed a lot of apps. Just make sure that you have not moved the apps in the app manager to the SDCard as this only movers them out of the Ext partition and in to the FAT32 partition.
I would give Leedroid another shot with your new SDCard.

I think I have just filled it lol got 75 apps but most of them are games big files, ill give starburst a go liking the sound of this ROM and if its true I should never fill the memory, if it not good ill go back to leedroid but start fresh format everythink.
With my old partition I did make it on windows like, so maybe thats whats happened, I am going to use gparted next time.

[Q] noob question - created ext4 partition on SD, but how to use it?

Hi,
I've created an ext4 partition on my SD with the intention of using it to store apps on
I used the gparted method described in http://forum.xda-developers.com/showthread.php?t=1016084
Now I've flashed a couple of ROM's (Oxygen, Redux and CM7) but have no idea how I can put apps on it
Additional question:
1) if you do a data, cache/dalvik wipe will the apps on the ext4 partition also be deleted or will they remain on it so you can reuse them in another ROM
2) I've rooted and s-offed my stock rom, can I use the partition I've created here as well? and if so, how?
thx

on all 3 roms youve mentioned you tried, app2sd is automstically setup on rom install. so you are already using app2sd.
1. yes if you wipe dsata, it wipes your apps on ext 4 partition
2. and yes, your aready using your partition once your using a app2sd rom. specific roms allow you to push your dalvik cache to your partition but it is not reccommended as it can slow donw your phone.

extra test: I've installed Leedroid with app2sd
when I install an app from the market my internal memory decreases and I cannot move it to SD card
I've created a 500mb partition, should this be visible as "internal memory"?
cheers

Some apps still need some space from the NAND internal memory.

Nope. But if you download "Quick system info" from the market, you will see where it's written A2SD your external partition and its used space.

If you are like me and want to install lots of apps app2sd is not good enough sorry I was on Leedroid superb ROM but I soon ran out of install memory because even if you move app2sd say you have 20mb app and move it to SD it will move like 16mb to SD and 4mb will still be on phone.
Best way is Data2SD I use startburst and have 2gb ext4 and my phone thinks it has 2gb internal memory
Make sure you backup and have a SD card class 4 and above some say class 2 fine I dont think so.

[Q] Best way to increase phone memory?

Hi there, a bit newbie to the Wildfire S that I bought to my girlfriend. I pretty familiar with CM7 for my HTC Aria, but not with stock roms.
The Wildfire S is rooted and runs a stock ROM with Hebrew support. that's the way is was bought from the store.
We've only installed gmail and maybe another app, and you are left with only 30MB of space? is that the way HTC designed this phone?
I want to increase the phone memory and use the SD-card. If I create a SD-ext of 1GB, what is the best method to move apps and cache to the card?

link2sd

thx for the quick response.
does link2sd allows for dalvik cache moving?
after installing link2sd is internal is the SD-ext (like in Cyanogen) or it's the internal phone memory?
also, if I have a rooted phone can I remove some of the sense apps?

Just do factory reset first, then you'll have about 150mb of memory free.
And yes, you can delete system apps if you are rooted.But be aware not to delete some important apps which can cause your phone not to fuction properly.
As for the extra memory, I would recommend link2sd, I'm using it, and I have 100 apps installed.
You could also use data2sd, but you need sdcard class 4+ for that, in order for it not to lag too much.

correct, deleting system apps is possible if rooted
however these are on the system partition, so will not increase phone memory.

NO

your internal phone memory still 150M，but apps can move to sdcard，I think the best way is data2sd .

I've already did a factory reset once and I didn't got 150MB of free internal memory it was much lower, that's why I was puzzled to see how quick the memory disappeared. If I had 150MB free I wouldn't have any problem cause I don't need too many apps on this phone.
Is it better to create sd-ext with ROM manager and than use link2sd?

after root I recommend SystemCleanup APP to update factory default Google apps in system (save over 40Mb of space). It's easier than link2sd

seems like a great app, tried it on my phone not the wildfire and had a few FC. but eventually managed to do everything.
No problem on the wildfire stock ROM? phone is rooted.

I'm using link2sd on a rooted stock ROM. No problems, works great, 30MB internal free, tens of apps installed/linked to the SD Card.

@trevike:
do you remember how much internal free space you had before using link2sd?

no problem whatsoever, just DO NOT move to system updated HTC apps (for example Clock widget). Those will stop working. FC for moved Google apps are normal until you reboot the phone.

I don't intended to do so. Just wondering if there is still something left on the phone or that's' what's left with Stock ROM installed.

If I remember correctly, I used to have 4x MB.

120MB, well I should check it in depth.

I just did a factory reset and wiped data completely. I've only got 62.6MB free in my data folder.
SD Maid tell me that (used/total)
system folder 199/269
internal data 87/150
any ideas how to check what's clogging the data folder?

bit strange that you have so much space used after factory reset
i find 'diskusage' app very useful to visually see what it is taking up space in each partition.

if I'm using this correctly, then on the data folder the dalvik cache is in charge for about 74 MB. that's after factory reset and 5 apps installed.

If it is rooted then install Link 2 SD. Delete some useless system apps and move apps like facebook, youtube etc to SD card..

If you're on stock rom rooted, link2sd is better than remove some stock apps.
If you're on custom rom or stock rom with custom kernel support init.d, you can use DT Apps2sd to move dalvik-cache. I think its better than link2sd.
Or/and if you have sdcard class 10, you might use data2sd.

[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.
Am i right ?

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] 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.

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..

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.

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

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.
