what exactly is app2sd??
I am using RAFDROID ROM on a TMOUS HD2
in the instructions he said that if I am using a euro HD2 with 512 rom I should partition my sd card
so I did not do that and flashed the rom on my NAND
then when I started using apps I noticed that after two weeks usage I have only 50 MB left!!!!
so I want to activate app2sd and move my apps to the sd card..
so please I need some help from the experienced users on this great forum that can advise me about what exactly is this and how to activate and use it
thanks in advance!!
Apps2sd moves your apps to the sdcard, usually to an ext 3/4 partition. I don't know about the ROM you're using, but on the one I use (mdj's Cyanogen 2.6), you can move apps to external storage like this: settings --> applications --> manage applications. Then select an app and there is an option to move to sdcard.
@freeincolorado, the method you described is not A2SD+, that method is called move2sd.
A2SD+ puts the dalvik cache as well as the applications in a EXT2/3/4 partition, usually called the sd-ext partition. This method will still show you that the application is in the ROM. However, the sd-ext is used instead, depending on the chief implementing A2SD+ in their ROM, the remaining ROM space is suppose to report the partition "sd-ext" free space, however, certain ROMs are not properly done in my view, and will report the userdata partition free space instead. Such as MDJ's Cyanomodgen 7+ Gingerbread.
How to use A2SD+
Usually, they require you to partition your SD Card into 2 primary partition. The first partition is FAT32 where you store all your extras, such as music, ebook, etc (Like how your SD card is presently used). The 2nd partition is EXT2/3/4 depending on your preference, most people do not use EXT2 anymore as it does not support Journaling, since data can be easily corrupted with a battery pull. EXT3 and EXT4 contains journaling feature, so when battery is pulled, data corruption is minimal.
NOT ALL ROMS SUPPORT EXT4. This is a kernel thing, so if the rom uses a kernel that does not use EXT4, then it will not read the partition.
A2SD+ has a nice feature as well, when you switch ROM, you do not need to re-install all the applications, since all applications are placed in the sd-ext folder, including the dalvik cache. However, this also includes the system default applications which might not be compatible with another rom build.
Hi, i am very new here and ilack some of the basic info. so i have couples of questions. thanks very much for your answers.
1. what is the internal memory of the htc hd2? and when you partition your sd to fat32 and ext3, will the internal memory be the sum of the ext3 and the phone internal storage?
2. when you want to flash your hd2 with a new rom. do you need to format both partitions of your sd card (fat32 and ext3)
3. when i tried the latest ultimate droid rom, i saw the author posted the rom and another thing called the layout (3.0.2.4_magldr_150M_partitionLayout_30M_cache). what does this do?
4. how do you make the phone to move or install apps in the ext3. and how do you back up those data and apps in the ext3?
and again, thanks guys for helping me out.
1 internal memory, do you mean what's available after a flash? 260 Meg or so with the small cm7 roms (typhoon for example)
No, the internal memory wont show the sum of internal plus ext BUT it will work as if it is. Say you install a 20meg program, internal mem goes down 20 but back up 20 after a restart.
2 no, when you perform the wipes through cwm it takes care of the ext partition and the .android folder on the fat32 for you.
Some apps may put data on the fat32, in which case you can delete those if you want or if you have isues.
3 the layout (clockworkmod, or cwm) sets up the various partitions on your nand (internal) memory, boot, system,cache,data. Without the layout there would be nowhere for the rom to flash into.
The main point of interest in cwm is the system partition size, big roms need big system partitions, sense roms for ex. need 250meg or more, typhoon needs 130. Flash a big rom to small layout fails, small rom on big layout wasted space.
4 you don't, if the rom says ap2sd enabled or words to that effect, it does it automatically. You can test this by loading up some apps then browsing the SD card on a Linux PC
When you run backups and such, it just does it, the phone has no idea that some of the info is on the SD, it treats it as internal.

i dont understand why is that? so if the rom is apps2sd supported, it will automatically install apps to ext3. then it makes sense to me that the mem goes down, but then why it goes back up???
Example, 250meg internal plus 1gig ext partition.
internal memory shows as 250meg,, install 20 Meg app which goes to ext partition BUT the system displays internal mem as 230, , you reboot the phone and check again and internal memory shows as 250 again.
oh, thanks alot, i get it. but which backup solution is the best? and how does backup using clockworldmod work? does it make a backup file to sd card?

Hi,
It depends what you want to back up.CWM backup will take a snapshot of your entire ROM system,data,settings,everything.A bit like a ghost image of a drive on your PC.
This way, if you install a new ROM and there is a problem,or you don't like it,you can RESTORE your original ROM and everything is back the way it was before.
CWM backup saves to the sd card.
If you just want to backup data,use something like Titanium Backup.
Hi Friends,
I am using Desire HD rom on my htc hd2, for me everything working great but my internal memory is only of 24MB
Please help me out....
please provide me the information om how to increase internal memory....
Please do not make two threads on the same issue.

it would be usefull if you told us exactly which desire hd rom, how you are running it (daf, cwm, sd card), and whether you have an ext partition on your sd card. Oh, and which phone you have, regular or tmous.
Sense roms are big, they take up a big chunk of the nand, so it is almost always essential to use app2sd and/or data2sd. (read the thread for the rom you have to know which it supports)
More accurate info = more accurate help.
rubbish info = rubbish guesswork help.

Thanks for your reply...
here is my details..
ROM : LeoRCMix S v.1.5 (RCMixS v.2.0) [Sense 2.1+3.0]
Running using : CWM
Phone : HTC HD2
Im using : TMOUS
I know i have to use app2sd/data2sd.. but im not sure how to config it.. even i tried to do but im struck with boot screen..
ok, so it should only need a 200 meg system partition, so my guess would be that you haven't set up the 1gb ext partition? you can do that through cwm (backup your sd card first, it will get formatted) and
but im not sure how to config it

you dont have to. it does it itself so long as you have the ext partition properly created. I also think that if you DONT have the ext partition set up yet, you will probably need to reinstal the rom after you DO set it up.
So, summary, , , question 1 - do you have an ext partition set up?
(Also, and this causes a lot of confusion, , , when the system uses an ext partition, it DOES NOT show the extra space in the available memory count, but it does get used, , so for example my phone shows 210MB or so free internal space, , , i install a 10MB probgram, that goes down to 200, BUT after i reboot, it goes back up to 210, , because the prog has actually installed to my 512MB ext partition, not the 210 internal space.)

then you are wasting 200 meg, , that rom says in post 1
EU and TMOUS: 200M system + 1GB EXT partition
Click to expand...
Click to collapse
that means you have 200 meg empty in your system partition, not being used.
Stuff that you install do not get installed to the system partition, nothing (or at least not apps / settings) gets put into the system partition, except the system at installation.
Do a full cwm backup, reflash using a 200MB partition layout, reflash the rom to teh new layout, restore your data and sd-ext partitions from advanced restore (in cwm) and you will recover the 200MB

Thanks a lot... now i understood wht is system and data memory.. now i got 200mb internal memory.. thanks again
same problem
i have a nand of 4.1.2 in my hd2 its pacman
it shows system memory only 13mb, i have removed all apps i installed earlier but still no space freed, can i atleast get the same 150mb back which i had earlier i.e any way to wipe all data on it/hard reset it?
is there any way of expanding the memory? because after i have installed 10-15 apps the memory vanished(even though i moved the apps to sdcard using app2sd) does that means i can not install more apps any way??
p.s i am a new user of android dont know how to install new rom etc so please explain the solution in simple steps.
Hello everyone,
is it possible to partition the MAIN memory (I mean the phone memory, not sd card) to fit the build I'm using perfectly? Like setting best size for boot partition, for system partition etc..., in order to have more space available for data internal partition?
I've found http://www.enfeuman.com/2011/06/01/how-to-fix-abnormal-internal-storage-space-on-htc-hd2/
but I really couldn't find an option in CMR to partition main memory.
If this is possible, can anyone tell me how? (I'd like it for my NAND ACA GB2.3.7 build)
And is it necessary to wipe the whole phone and do (flash) everything over again?

Wipe data
to set the partition sizes, try clk 1.6 and use fastboot commands to resize the partitions.
When you do this, you will have to re flash the rom.
Thanks, ill try that.

HTC HD2
ACA GB 237 CM7
kernel 2.6.32.15
NAND Android ROCKS!
Hi,
Short / long story:
I have long time unused HTC HD2.
With Android (NexusHD2-KitKat-CM11.0_V4.5.zip is the file which I found in backup, so I assume this is what I install - sorry, it was long time ago.
Some time ago I need microSD card so I took it from my HD2, I did backup only windows FAT32 partition.
Now, I need to run my HD2 , I have install microSD 2 GB (800 MB FAT32 + 1GB Ext4) but is not working correctly.
It starting I can install Teamviewer, but when I need to install HTC module for teamviewer it's telling me that is not enough storage.
Quite often is restarting and after restart not keeping any settings (wi-fi) app installed (teamviewer) it's resetting each time to factory settings.
In Settings - Storage shows 'Total space' - Available 0.00 bytes
I did what is instructed on this webpage but it didn't help http://android.stackexchange.com/qu...mory-in-android-nand-roms-cannot-install-apps
Can anybody advise me which is the easiest way to make my HD2 working properly? Means have enough memory to do anything.
The purpose of restoring my HD2 is working as a router, tethering machine. I need to share internet from mobile network for smart TV and Tablet over wi-fi. It will be unattended so I need remote control access (team viewer host).
I'm open for a suggestion of changing the ROM if there is something reasonable easy and described (as I'm not big ROM expert). i've seen a ROM list for HD2, is too long.
Thanks in advance for your help.
it sounds like you are missing a data partition, perhaps the sdcard you used before had an ext4 partition which your new one does not have. Use recovery, in nand, to create an ext4 partition, then boot into rom, might work.

Hi,
Thanks for your reply.
I did Ext4 by MiniTool Partition under Windows primarily.
And later in recovery, I have setup 1024MB and swap = 0 M.
It didn't help.
Should I mount it or so?
Update:
I have a look in log in nand - recovery and it's says that my second partition is Ext3 not Ext4.
And there is no way to change it.
What is your nand recovery? version?
Clk or magldr?
The recovery might say ext3 when it means ext4, but it does not seem right.

It says on the top bar screen 'CWM-based on Recovery v5.0.2.6' but was install with ROM so should be fine.
try using the recovery to format the ext partition to ext2 or 3 then use it again to ext4

As I said, I have created and formatted partitions under windows FAT32 & Ext4 and then under recovery, there was no choice of the file system file, I can only choose the size. And it was formatted to Ext3 - log saying.
