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.
okay, so i just flashed Kyrillos' ROM (7.0, then upgraded to 7.1)
now i want to partition my SD card to create SWAP, and also to create a partition to add extra space to the internal memory (what is it's name, again?)
i don't know too much about what type of partition to do, so can you guide me through the process or give me a link where i can read further?
also, what are the recommended partition sizes?
PS : i have a 4GB, class 4 SD card. and i just downloaded minitool.

you can flash g3mod kernel and do partition in uer sd card.mine is 8 GB Card, Class 4...I have 1024 as Ext Size and 256 as SWAP. so the choice is uers.

I've been looking for that too , Thanks
okay, i didn't know i'd need a card reader :/
i don't have it. any way to partition it using the CWM?
and what sizes do you recommend? i was thinking maybe 128 MB SWAP and 512 as the internal memory size.
and do i have to flash the g3mod kernel? i'm currently running 2.6.32.9. this came with Kyrillos' 7.0.
wait, i'm getting confused now. when i flash Kryillos' ROM 7.0, does my kernel also get changed? or am i running the stock kernel?
and the CWM i'm talking about is just.. recovery. the one that i access using vol up + vol down + home key + power key.
that also has partition SD card option under advanced > partition SD card.
will this do or do i have to flash g3mod kernel?
Once you flash Kryillos' ROM you are no longer running the stock kernel
CWM is ClockWorkMod Recovery and it comes with the ROM and so it's different (Google it)
And about making a SWAP, well , you might wanna read this -
"1. An Android swap partition must live on your SD card. SD cards are very, very slow memory. They are 100 to 1000x slower than a SIM. They are 10 to 100x slower than a hard drive. They are marginally faster than a network connection. When an application is “swapped out” it is copied into this very slow memory, and copied back to physical memory when it needs to run. On the other hand, when an app needs to be restarted after being terminated by Android, it is loaded not from the SD card but from the device’s (relatively) fast physical memory.
2. When an Android app is terminated because of low memory, it decides what information must be persisted to represent it’s state. This can be very, very small. For example, it might be an integer index into a database. When an app is moved into virtual memory, the OS has no idea what’s important. It just moves the application in whole. It can’t be smart about it.
3. Having swap actually prevents the native Android memory management scheme from activating. The system sees memory and doesn’t distinguish between physical and virtual. It will therefore prefer swap over the native Android memory management scheme, and won’t activate the native scheme until swap is full.
4. Having swap requires some overhead of system resources."

Nice and informative.
My epic 4g is running ei22 Legendary v.1 with the samurai 3.3 assassin kernel. I am a bit of an app whore and have loading it up with nearly 260 apps. I have accomplished this with the use of a 2.5gb ext4 partiton on my class10 16gb sd card, the darktremor script and the a2sdgui app. With this setup I am have all the storage I need and then some.
My question is; is it possible to repartition in order for more ram as opposed to storage?
I have excluded a fair amount of apps from starting up at boot, and I aggressively manage my memory with a memory manager, but I still feel I need more ram.

I believe ram is a completely different chip in the phone, opposed to the storage space, because it functions a lot differently. But I may be wrong.

Wait, WHAT?! The ram isn't in our SD cards?! You don't say! Although I was starting to suspect something when I noticed that if I remove the SD card (or mount it as USB storage), the phone keeps functioning, and I know that can't happen with any computer when the ram is removed...
The OP only mentioned partitioning of the SD card, not internal storage. Also, ram isn't partitioned... he is most likely referring to creating a swap partition on his sd card, which the system would then use as additional storage space for temporary data that would normally be held in ram. However, the CPU still needs the data in ram in order to interact with it, so if the required data is actually in the swap partition, then the system would need to free up some room in ram for the required data (often, by swapping places with data in ram that isn't currently needed, hence the name...
@OP - I'm fairly certain the Epic doesn't currently support swap files/partitions, but I recall seeing mention of other android phones with that ability. But it shouldn't be necessary, our phones have enough ram - if you are running out of memory (errors, not simply seeing a low amount of available ram) then you either have something wrong with your phone, or you need to stop trying to keep all of your favorite 3d games loaded at the same time, lol

Our phone does have the ability to support swap. Some Bonsai releases support swap. First you'd have to make sure the /sdcard was partitioned for swap to have a place to reside. Then, it'd have to be enabled in the kernel and there are tweaks to "swapiness" that sets aggressiveness of swap use - basically swap enable will try to take dormant items in RAM and move them to SWAP to free up RAM. You can run 'free' command from the terminal to see how much swap is available and in use.
All that said - I don't think the OP is referring to SWAP or RAM - as those would only help free up running memory. OP seems to be interested in more room on his OneNAND data partition and SDCard for Apps to be installed.
RE OP: CM7 MTD downsized the /cache partition in OneNAND and gave a sizeable boost to /data space for more apps (see images posted by AproSamurai showing free space). If you run the command 'df -h' from the terminal you'll see the size (total, used, available) of /system, /data, and /cache. On CM7 I have the following sizes, respectively, 268.5M, 676.5M, and 25M. Side note: The 25M cache isn't large enough for all Market apps to download though so noobnl fixed by mounting /cache/download on /data partition (MTDBlock3) to allow for larger apps to cache in download directory before install.
If you're sticking with a GB TW ROM though - I don't understand your setup. Why not just use the built in GB capability to move Apps to SD Card in Settings -> Applications (select app and "move to SD card" for those compatible/capable)? I don't get why you need to create a separate EXT4 partition and use 3rd party tools. Can you elaborate on why they wouldn't work?
Rereading your OP - NO - you can't get more RAM to fit in the phone. It's got what it's got and you can't get more from it. Enabling SWAP may help, terminating resident apps in the background MAY help, but at the end of the day you can't increase the RAM available. You'll need to better manage what you have.
Please don't confuse RAM with storage memory - that got me turned around in your OP.
Sorry for confusing you, if I did. I wasn't interested in partitioning my sd card for more ram on the sd card. My interest is in using the cache space for ram. I don't understand how a phone can be stated as having 512mb's of ram and 1gb of rom and not be. Yet all the epic can muster is 362mb of ram, most of our performance issues are due to that... If there was a way to unlock any more ram in samsung's specs claim I wanted to know.

I would have loved to use the .android folder to save my apps but my dalvik cache would fill the internal space and limit me to about 180 apps. With the Darktremor script and a2sdgui I am able to put my Dalvik on the ext4 partition of my SD card.

Hello all,
I have CM9 nightly installed on a 32GB microSD and I have just run into a weird problem. I still have 27GB left open BUT when I try to download magazines and install apps, it's saying I'm out of room or running out of room. Anyone have any idea why that might be?
Is it possible it's installing things to the EMMC? If so, how do I change that?
Sorry if this a n00b question. Thanks in advance for your help.

Android has 3 major areas where stuff is stored. The system partition holds all the OS stuff plus has an area for system apps. The data partition is were downloaded apps get stored normally. The media or sdcard area is normally used for music, videos, pictures and also where some apps store any working data.
The system and data areas are of relatively fixed sizes even though they are all on the actual SD card. For your 32GB SD card it is probably "460M system, 975M data, rest is FAT for sdcard" from veryGreen post.
So your error message is being triggered probably because the 975M data partition is full. Typically this enough to hold about 150 - 200 apps depending on their size, but some games can take quite a lot.
You can check memory usage by going into settings and looking under apps.
What can you do about it? On an SD card install the simplest way is to use ANdroids capability to move apps from the standard data partition to the sdcard partition. Not all apps can be moved but many can and this will then free up space in your data partition.
Get the Apps2Sd app to help you manage this process.
I haven't run from a sdcard in quitevawhile, buy it sounds like the card didn't get repartitioned after making it into a bootable. After you burn an image to a card, you need to use an application like Easus, a disk partitioning tool (free for home use for windows, I believe) t repartition the card and make use if the remaining space.

I think the partitioning must have worked otherwise it wouldn't function at all.
You could change data partition size to give more space to the data partition if you are careful. I've done that on emmc prior to install. I've never tried it on an SD card after install and it's possible it might muck something else up. However, the basic point is that apps and related content go into data by default. The big part of the SD card left over from the initial install is intended for media.
Compare it to a phone. The data partition in the internal phone memory is fixed and can run out of space if lots of apps are installed. If you plug an SD expansion card into a phone it allows you to store lots music, video, etc but unless you move apps to the SD card then your original data space is unchanged. That's why app users can complain if a memory hungry app can't be moved to SD.
Maybe you can teach me something here. I am not sure I understand.
When I formatted an 8 gig card to run cm7.1, I was able to use it to boot but had the rest of memory unavailable for use. It wasn't until I redid the process and then reformatted the partitions to have the remaining space available. Only then was I able to use the remaining 6 gigabyte or whatever. I had the four partitions in both instances, and the card worked, it just wasn't available because all the space was allocated to the wrong partition. Which I rectified with Easus, I'm pretty sure.
What I guess I am saying, isbthat there are some tools that could be used, although I maybe wrong. It just seems counter-intuitive that the OP should have to use App2SD and otherworkarounds when theybhave 32 gigs to play with. I think Easus lets you define those partitions anyway you like, with the 29 gigs or so that is left once you allocate the system stuff.
Like I sad, I maybe just don't understand this very well, it is something I did when I was first learning about rooting, before I figured there was no real reason not to go internal.

The various partitions have different purposes. It's not that they are unavailable for use. You want each area to have sufficient room for what you want but not necessarily too big because that then is wasted and is subtracting from the other areas.
First there is the boot partition containing the boot images. This can be small.
Next you have the system partition (~500MB) which can be fairly small because the OS does not take a lot of room and the system apps are relatively fixed in size and you don't need to add extra to that.
Next you have the data partition where downloaded apps and some of their associated data lives. You want this to be fairly big to accommodate a decent number of apps but it doesn't need to be huge. Apps vary in size from 100s of Kbytes up to say 20MB or more. So a 1GB data partition can typically hold about 200 apps.
On an SD card that then leaves the rest of space for a sdcard partition where media can be stored like video, pictures and music plus some apps will also require some working space on there.
So on an SD card install the main balance is between data and sdcard. If you were to make the data partition larger to accommodate more downloaded apps then you reduce the amount of space for music, video etc. But you do want enough space to hold a decent number of apps. The standard verygreen SD card installer sets the balance at ~1GB data and the rest sdcard for media. Now if you never wanted to put much media files on the SD card and you want to be able to download thousands of apps then that would be an argument for setting the balance the other way.
Now if you install to the internal memory the same scenario applies but you have an additional partition confusingly called emmc. Your boot, system and data areas are on the internal memory. The left over internal area is the emmc partition and the sd card is now normally set up to be a single sdcard partition.
Both the emmc and the sd card are typically used to hold media files.
The size of the data and emmc partition in the internal memory can be varied before you do the install by some partitoning zip tools and there is a thread dedicated to that.
By default as supplied new Nooks have a 5GB internal data partition and a 1GB emmc. Many people think that is not a great choice as it is really difficult to run out of app space with 5GB and it means there is only 1GB internal space for media and the unused data space is wasted. By repartitoning to say 2GB data and 4GB emmc then you get plenty of space for apps and release space for more media.
You are right that using something like Apps2Sd would seem unnecessary when you have lots of free space. It is effectively a work-around to let you use some of the sdcard as extra data area if you run out of the data area that has been allocated. Actually on an SD card install there is not much of a downside in that moving an app from data to sdcard as it is still all on the same SD card. For an internal memory install it is nice to have a big enough data partiton to make moving apps to the SD card unnecessary.
hi guys new user of HTC HD2 here (previous motorola defy user)
so I got this phone yesterday thru swapping, and this phone is awesome, but I was rather disappointed with the internal memory. Mines got 186mb of application space so I always get memory full prompts. I know there is a mod to increase the size.
I flashed paranoid android this morning and boy is it good looking
I just want to increase my internal memory and Id be happy with it
what's the maximum I can a lot to it?

OK first things first,
Are you familiar with the 'stuff' of the HD2? MAGLDR bootloader, ClockworkMod Recovery(CWM)? sd-ext partitions?
well I'm trying to learn this terms but this is gonna take a while I think,
the Previous owner has installed magdlr 1.13 and clockworkmod and I have flashed paranoid android rom this morning. So I do have a recovery
sd-ext partion not so much
**okay okay, you will need to do a lot of research about your device and using it to its full potential; too much that it can't be explained within one post **
but here is a method I found in xda of performing a sd-ext partition within cwm:
> GO to advance and then partition SD card
> Remember this will wipe the sd card so back everything up if need be
> Choose how much space you want, 1024mb is recommended, on the partition then then choose 0MB for swap
>PLEASE NOTE PARTITIONING WILL WIPE THE SD CARD!
>and hey presto your done
> from here you can install link2sd and your set to go. -note, you will need to read about link2sd before use. just search it
There are many benifits of this using EXT-Partition such as you apps will automatically transfer to your partition meaning you will free space on your internal storage!
apologies if there's any misinformation there, quite tired :$

ah I see, so basically the sd card will be detected as and internal card and I won't face memory full errors whenever uninstalling?
but I can just use link2sd app to transfer apps to sd card manually right?
I was wondering why I only have 186mb of internal memory wherein in GSM arena it says at least 512mb.
what I want to do is a phone modification to increase it, just in case the sd card was corrupted, I still have my apps on the phone memory
thanks for the reply though, if you can add something feel free :victory:

It says 186Mb because when you flash CWM, you also partition your NAND to run Android. Essentially, the storage you get is 512Mb-CWM partition size, although normally it's lower as there are probably things other than this installed to the NAND.
Thank you

Well it depends on the partition size you're currently using. If it's already the minimum for your ROM then no you can't increase the storage by repartitioning the NAND, but if it's any more than the minimum then you can increase this, by reflashing recovery with the correct size. Make a full backup in CWM first though.
so I reflashed 150MB recovery partition and flashed AOKP build by xylograph
now I have 217MB of internal memory
what should I flash so I can have more space?
the less is your recovery partition - more internal memory you get. Minimal recovery partition can be about 100 mb for some light roms I belive. So you can get 50 more mb than you hav now.
You've mentioned 300mb earlier, even if you get your desired 300mb it's gonna get filled up very soon.
I would advise you as was mentioned above to borrow 1gb from your sd card for sd-ext partition. Most of the roms support from the box (without intsalling any additional apps or scripts) sd-ext partition and install apps by default on that partiotion, Paranoid Android does, for instance, actually 80% of the roms do as well...
I don't know if it means anything, but you could look into a US HD2. Its got 1024 mb internal memory! That's double!
ok maybe ill experiment with this sd-ext partition
