Hi world!
I don't know if this is the right place to ask for this feature, since I guess this is more hardware dependent than just plain programming:
Is it possible to create a bootable partition in the internal memory of the Diamond?
This could possible kill my need for USB memory once and for all.
hello,
i do it with sd-cards under linux.
one possible way is to use vmware.
when you put your diamond to windows, select on diamond harddisc.
vmware-linux have to recognized a harddisc.
now you can make partitions with fdisk.
i know, my guideapplication is very grossly. but the two sentence
costs you more than five or more houers of work, if you dont know,
how to use fdisk or vmware with linux inside.
why you want partition your internal memory?
okokur
I do it in my X51V, it need if you want start a kernel linux boot.
with Linux partition manager you must create small partition swap in strorage memory and put the kernel img here, in the storage card you must put the haret.exe + config file.
the commands are:
The SD card needs to be partitioned into two partitions: one small FAT partition that WinCE can see, and one EXT2 partition used as root file system. I'll assume that the block device of the SD card is called /dev/sda. Replace this with the correct device on your system. Instruction could be slightly different for each version of fdisk :
* Delete all partitions on the SD card:
fdisk /dev/sda
d
1
d
2
d
3
* Create partitions, for example a 10MB /dev/sda1 and /dev/sda2 using the rest:
fdisk /dev/sda
n
p
1
<default> (should be cylinder 1)
+10M
n
p
2
<default>
<default> (should be last cylinder of the card)
t
1
4
w
* Create file systems, a VFAT on /dev/sda1 and EXT2 on /dev/sda2:
mkdosfs /dev/sda1
mke2fs /dev/sda2
* Copy HaRET, the kernel and default.txt onto sda1:
mount /dev/sda1 /mnt
[diamond] cp zImage???????????????/mnt/zImage
cp haret-0.4.8.exe /mnt/haret.exe
cp default.txt /mnt/default.txt
umount /dev/sda1
mount /dev/sda2 /mnt
[diamond] bzcat diamond?????????.rootfs.tar.bz2 | (cd /mnt; tar x)
umount /mnt
3) Boot
start haret.exe and tap the "Run" button...
enable Mirror Mode(Start -> Settings -> System>Mirror).
for Diamond you need Zimage and rootfs
look here http://linuxtogo.org/~lgorris/kaiser-bootkit/
for other problem or command here

I think it just works fine...
But Haret doesn't work on Diamond.
Hi guys,
sorry because this has probably been answered somewhere but I couldn't find it ....
So here it goes: I just installed Modaco's ROM and it works perfectly. Now I would like my apps to install directly on the SD card.
What I understand is that I need to create a EXT3 partition but I don't know what the hell that means, nor how to do it.
I just put my SD card in the hero, didn't format anything ....
Dould you give a step by step guide ? On how to create that EXT3 partition, how to use A2SD afterwards ? Also, what to do with the currently installed applications ?
Thanks
Geeum

Just use MoDaCo's custom ROMs. (It will do it automatically)
can app2sd work with official ROMs not rooted?
Hi guys I finally partitioned my sdcard to have an ext3 partition.
I thought A2SD was automatic but apparently applications don't go to the sdcard: my phone memory has changed after I installed an app ...
Here is what I get if I type the 'print' command on parted
Code:
(parted) print
print
print
Model: SD 00000 (sd/mmc)
Disk /dev/block/mmcblk0: 8166MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 512B 7110MB 7110MB primary fat32 lba
2 7110MB 8134MB 1024MB primary ext3
3 8134MB 8166MB 32.3MB primary linux-swap(v1)
So I DO have ext3. Then I found this post that explains how to check if A2SD is working:
Thanks! Here is my way to check if a2sd is working:
Check if the ext3 partition exists (please see androidandme.com for details):
Code:
# mount | grep mmcblk0p2
mount | grep mmcblk0p2
/dev/block/mmcblk0p2 on /system/sd type ext3 (rw,noatime,nodiratime,errors=continue,data=ordered)
Compare available/used space on mmcblk0p2:
Code:
adb shell
# df
df
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 98520 0 98520 0% /dev
tmpfs 4096 0 4096 0% /sqlite_stmt_journals

/dev/block/mmcblk0p2 468331 11767 431579 3% /system/sd
Now install an app from the market (as suggested by fleming222) and again run "df". Compare the available (or used) space on /dev/block/mmcblk0p2 with the first "df".

This is what I get (I can see on the first line that my ext3 is not listed ... weird)

The best way to do it if your not too good with the adb commands is to install the AMON recovery image for Hero.
It has all the options to create the correct sd card partitions from the recovery mode, then just install your custom rom and everything should work.
You will need to format your sd card so you may want to create a backup of it. And I would suggest that you wipe the phone clean as well. Once you install the modaco rom it automatically moves all of your apps to the sd card.
The link for the recovery image is here:
http://forum.xda-developers.com/showthread.php?t=561124
You will also need Instant Root (http://neilandtheresa.co.uk/Android/), which you should install first, it is an .apk file so you will need a file manager for your phone. It should pop up with a notification "instant root was successfully" or along those lines. (If you have a problem installing Instant Root make sure Settings>Applications>Unknown Sources is checked)
You should then place the AMON recovery image onto the sdcard making sure it is not put into any folders (root).
Instant root then allows for root access with adb shell using the following 2 commands:
1) adb shell
then
2) su
the icon should change from a $ to #.
Now flash the recovery image with the following command:
flash_image recovery /sdcard/recovery-RA-HERO-v1.2.3.img
That should do it, remove the usb and battery and once you have replaced the battery boot into recovery mode.
I ran the following commands in this order from recvoery mode:
- Wipe data + cache (factory reset)
- Wipe ext partition on SD-card
- Wipe Dalvik-cache on SD-card (NOT on /data !) [email protected] ALWAYS WORK
- Partition SD-card : 500MB Ext2, 32MB Swap, remaining Fat32
- Convert ext2 to ext3
- Installed ROM
Hope this helps
Hi and thanks for your reply. I finally sorted my problem, I was typing the commands from the recovery console, and now my ext3 shows:
Code:
# mount | grep mmcblk0p2
mount | grep mmcblk0p2
/dev/block/mmcblk0p2 on /system/sd type ext3 (rw,noatime,nodiratime,errors=conti
nue,data=ordered)
I checked the space with df, and I can see it changing when installing apps.
However, so does the 'internal memory of the phone' in the settings panel; it keeps getting smaller as I install apps
Why is that ?
really want to do this but i find it all to hard and confusing

I think this is inevitable as the app uses some part of the phone memory for cache files etc (I am not 100% certain on this, just saw it written in an older post on the same topic).
I do not know if this is a coincidence but for some reason I have tried partitioning manually (the way your doing it) in the past and have recently used the AMON recovery image for partitioning instead. I notice that the recovery image tends to use less of the internal storage for each installed app, I don't know why but you could try it out yourself.
guys, i am using modaco's 2.6 rom. so if i just create partitions this custom rom will automatically install newly installed apps to the sd card. right?
but what if i already got many apps installed? will those be deleted while creating partitions?
is there any way so that i can backup the whole application folder and restore after creating partitions?
cheers
apparently if you do ext2 + swap + fat32, you can't do a Nandroid backup (it keeps giving errors). anyone got similar issues?

Tested Roms (will not test SD-SWAP on most)
These are some roms I've tried the enabler on, since I don't use a swap partition on my SD card I don't bother testing it and usually don't advise using SD-Swap. It's only in the enabler for sake of completeness. All sd-ext tests are done as ext4 unless otherwise specified.
Andromadus Slim Bean Build 6 (JB 4.2.2)
DataSwap - OK
SD-EXT - OK
SD-Swap - Untested
Andromadus Mimicry 1.3+ (CM9 ICS)
DataSwap - OK
SD-EXT - OK
SD-SWAP - Not Tested
Andromadus Test builds - Jelly Bean(CM10) - Build #61+
DataSwap - OK
SD-EXT - OK
SD-SWAP - Not Tested
Virtuous Infinity 1.31.0 Alpha3 (Full Sense 4.0)
DataSwap - ISSUES*
SD-EXT - OK
SD-SWAP - Not Tested
*The init script in /system/init.d/80dataswap didn't automatically execute upon boot. However when running it manually it worked fine. (might be fixed in 1.3, have not tested yet).
ILWT CM7 (Build 471) with ILWT CM7 Kernel
DataSwap - OK
SD-EXT (as ext4) - Not Working *
SD-EXT (as ext3) - OK
SD-SWAP - Not Tested
* When /sd-ext formated as ext4 was not working, I used 4EXT recovery to format it to ext3 under tools -> wipe/format => ext3, rebooted and it worked.
Gen.Y VisionX B4
DataSwap - FIXED*
SD-EXT - OK
SD-SWAP - Not Tested
*Fixed in 1.3 to include the busybox prefix, 1.4 to include shebang (#!) string.
UPDATED Aug 19th 2012
v1.4 Changes from 1.3
Added shebang (#!) string to dataswap scripts
Changed init script permissions from 750 to 755
v1.3 Changes from 1.2
Updated dataswap script to use busybox prefix for swapon/mkswap
Updated SD-Swap to use busybox prefix
v1.2 Changes from 1.1
Added addon.d support for supporting Roms
v1.1 Changes from 1.0
Fixed a bug where 96MB option installed 64MB
Added 128MB DataSwap Option
Added ability to enable SD-Swap (choose w/ Sd-Ext if SD-Ext partition exists, without w/o)
Changes from previous version (1.0):
Migrated to Aroma 2.50 Installer
Removed SD-Swap activation from SD-Ext Enabler Script
SD-Ext Init Script made smaller (Specific to HTC Vision/G2/Desire-Z now)
Now with the Aroma installer allowing for an easier selection of mods to be applied.
DataSwap Enabler
64MB DataSwap (Recommended for some Roms)
96MB Option (heavier multitasking)
Skip/Off (do nothing, skip to next mod)
Remove (removes the swap file and swap script)
SD-Ext Enabler
Enabled (detects and migrates /data/app and /data/app-private to /sd-ext)
Skip/Off (Do nothing, leaves as-is)
Revert (Moves all apps from sd-ext back to /data and removes script)
SD-Swap Enabler
Enabled w/ SD-Ext - does not enable Sd-EXT, simply enables SD-Swap correctly if SD-Ext partition also exists
Enabled w/o SD-Ext - enables SD-Swap when no SD-Ext partition exists on the SD card
Skip/Ignore - Does nothing/skips
Remove - Removes the SD-Swap enabling script
Do not enable SD-Swap if your Rom Already supports SD-Swap out of the box (elitemod, etc), so double check first.
If you don't have an SD-Ext partition, then Swap partition will be the 2nd partition on the SD Card, otherwise it's the 3rd. Thus why the installer makes the distinction for with and without SD-Ext when it comes to SD-Swap options.
Regarding addon.d support
In roms that support /system/addon.d, during an upgrade (flashing a new rom) shell scripts in /system/addon.d would be utilized by the backuptool allowing the ability to upgrade the rom without having to re-flash the extra roms.
For example in my /system/addon.d/ folder there will be a 60-kbeezie.sh script when flashing version 1.2. If you were to upgrade your rom (for example Mimicry 1.3.2 to 1.3.3), the dataswap, sd-ext, sd-swap init scripts will be backed up, and then restored after the new rom has been upgraded (the same way google apps is preserved in the 1.3.3 upgrade, so no need to re-flash google apps).
So on any roms that support addon.d, you'll be able to upgrade your rom to the next version without having to reflash the dataswap/sd-ext enabler.
What is DataSwap
Dramatically improves multitasking. (Can be used with or without SuperChargerV6).
In layman's terms it's a swapfile placed in the /data partition, where it should be faster than using a swap partition on the SD card. Unlike SDSwap repartitioning is not needed. Every reboot removes and re-adds the file so that the file isn't working on one specific part of the emmc chip all the time (one of the downsides to SD Swap).
More information can be found on the original DataSwap post by Nik3r
http://forum.xda-developers.com/showpost.php?p=27608489&postcount=153
What is SD-EXT
The /sd-ext mount is a partition on the SD card formatted as ext4 allowing you more app storage space. Unlike other means of running apps off an /sd-ext partition, this mod/script only maps /data/app and /data/app-private to the /sd-ext leaving caching and other features on the internal memory where it is most efficient.
Because SD-EXT in this case is replacing your /data/app and /data/app-private you want to ideally make it bigger than your /data partition (no less than 1.5GB, 2GB is a good fit). However bear in mind that if you wish to revert back to using only internal storage, you'll want to make sure that your /data partition has enough room for the applications to be moved back.
Why Both Together?
When all the user apps are placed on /sd-ext you are typically freed of roughly 600-700MB of storage on your /data partition. Doing so gives the swap file more room to move about the /data partition, but also splits the I/O (input/output traffic) between your SD card for apps, and internal memory for swap/cache, which may improve the overall experience (and may also prolong the life of your device... in theory).
Also You are not as likely to run the risk of /data suddenly running out of memory because a 64MB swap file is created on top of your app space. (i.e.: say you only have 70MB free in /data from all your apps, and you reboot to apply DataSwap but not SD-EXT, your /data would become dangerously close to being full when the swapfile is created). Hence DataSwap should be used in conjunction with SD-Ext.
Tips
If you currently use EliteMod ICS, you should be able to use this zip to revert a SD-Ext installation back to internal memory. Just make sure you re-partition the SD card after reverting so that EliteMod's init script doesn't automatically move the applications back to sd-ext upon the next reboot.
The effect of DataSwap will greatly depend on how your rom handles memory. For example on Mimicry with SuperChargerV6 option selected, the DataSwap will rarely be used, but it is handy for rapid burst of memory when apps need it. Without SuperChargerV6 the dataswap does get used a bit more often with more apps active in memory, but the extent of it varies on your rom's configuration.
If you're considering reverting SD-EXT apps back to the internal memory the following command will show you partition usage (can be run in either terminal emulator, or adb shell):
Code:
busybox df -hm
With an output similar to this:
Code:
Filesystem Size Used Available Use% Mounted on
tmpfs 183.6M 60.0K 183.5M 0% /dev
tmpfs 183.6M 0 183.6M 0% /mnt/asec

/dev/block/mmcblk1p2 2.0G 374.4M 1.6G 19% /data/app-private
Note how above /data has 834MB available, and /sd-ext is using 374MB, meaning /data will have enough room for the apps if you wish to revert.
DISCLAIMER
There is no guarantee this will work with all Roms, I've only tested it on a small handful of ICS roms (mimicry 1.3.1, EliteMod ICS). It is known to be skittish/non-working with most GB roms.
Do not ask if this would work on JellyBean, there's quite a bit of work that still needs to be done with JellyBean, and trying this on an alpha/preview JB rom will not likely work, plus I won't provide any support for someone complaining that it doesn't work on JellyBean as I'm not using JB right now.
Credits and Thanks
Thanks to Nik3r who originally wrote both scripts for his own EliteMod ICS Rom which provides both of these features natively to the rom (DataSwap is a seperate zip, but the rom itself already has SD-Ext/Swap support built in).
Thanks to blk_jack for providing support and information regarding the Aroma installer and assistance in testing swap on mimicry.
Checking if it worked
Typing free in either Terminal Emulator or adb shell, should show the approximate dataswap size on the swap line:
Code:
total used free shared buffers
Mem: 375916 372156 3760 0 4352
-/+ buffers: 367804 8112
Swap: 65532 17132 48400
For checking to see if SD-EXT is active, you can use the following command in terminal emulator or adb shell
Code:
adb shell busybox df -hm
Code:
Filesystem Size Used Available Use% Mounted on
tmpfs 183.6M 60.0K 183.5M 0% /dev

/dev/block/vold/179:65
12.8G 7.8G 5.1G 61% /mnt/secure/asec
You'll see that /sd-ext /data/app /data/app-private are identical in their capacity, usage and free space.
AGAIN there is no garantee it will work in every rom, if you do find success with it, post what rom and version you are using.

I supposed its possible both features are just init.d scripts. But I don't know enough about the shell scripting differences between GB and ICS to know whether or not there will be conflicts. In theory you could take the sdparts init from elitmod cm7 and replace it in the zip (or I can when I get home)
The data swap one is very simple and may work without a problem, I'm more concerned about the sdext part.

at first try the data swap (since you have high hopes, and since i'm more interested in it), then try the sdext...
data swap can be used without sdext, but as you mentioned, using both allows the data swap file to have more physical space to move around on every reboot...
but if everything woked out, i'll be using the data swap without sdext... cuz i really don't have sd space (i dunno why)

Yea I mean if you flash the zip and don't have an sd-ext partition, nothing should happen, since it'll only activate if it see's an sd-ext partition.
And to see what I mean about the dataswap init script, this is all it is:
Code:
# Enables swap on data partition
# file is /data/local/swap
# POI: this can be used along with sdcard swap partition
# the load will be automatically evenly divided between the two locations
mv /data/local/swap /data/local/swap.old
busybox dd if=/dev/zero of=/data/local/swap bs=1M count=64
chmod 0600 /data/local/swap
mkswap /data/local/swap
swapon /data/local/swap
rm -f /data/local/swap.old
All it does is move the swap file to old (which course only does it if it exists), create a file of 64MB, make it a swap file, and turn it on. Rinse and repeat every time you boot up the phone.
I doubt those commands changed much from GB to ICS. The 04sdcardparts file on the other hand is around 240 lines. I'll unpack the one from EliteMod CM7 and run a diff on them to see if they're any different (if not, its because he simply migrated his latest work from ICS that he's currently on, to CM7 to fix the bug, which I think you were the one to report initially).
But yea as long as you understand the caveats of using DataSwap without an sd-ext I don't think it would be a major problem (just probably wouldn't perform as well in my opinion since you're accessing the same device for both swap and standard apps).

well, i have sdswap that is on too so this might increase multitasking and swap speed a little more...

ui_print("Modifying permissions...");
set_perm(0, 0, 0775, "/system/etc/init.d/80dataswap");
set_perm(0, 0, 0775, "/system/etc/init.d/04sdcardparts");
unmount("/system");
...
So technically if you want to do it manually all you have to do is save that as 80dataswap in /system/etc/init.d and make sure to set chmod 0775 on it, and reboot.
I just took a look at the one on EliteMod CM7, it's different and a heck of a lot smaller. It's a file called 10apps2sd and only 39 lines. I'm almost wondering though if other aspects of the /sd-ext partition are in other init scripts (i.e.: initialized variables and such set before reaching that level of the init).
Also the EliteMod CM7 thread doesn't seem to make any mentions of DataSwap, was probably only created for his ICS rom (though the script seems like it'd work on just about any rom supporting those commands and had enough free space to work with).
In fact because nothing has changed dataswap wise from his own dataswap zip you could just grab it from his thread whichever size you want and flash it. It'd be identical to this bundled one without the sd-ext.
well init.d commands are supported for all Vision ROMs, and i'm sure they are supported on CM builds. so now the problem only lies on auto-sdext for GB.
EDIT: ok, before i reboot:
i have a 128MB sd swap already active... how do i know that the 64MB data swap is active too?
you knew that by noticing the 64MB in "free"command ... but i already have a 128MB swap in "free" command

Got a suggestion for a good GB-based rom you were thinking of?

lol, tsubus in his ILWT thread was talking about it 2 days ago... if it works, i might switch back to his ROM

Well later tonight (i.e.: after the hours someone might likely call/text), I'll give ILWT a try. Will install it clean, install some apps, then apply the mod, then install some more apps so that I know 1) already installed apps get moved, and 2) it continues to work even if you reboot.

i've configured the dataswap script... i'll reboot and report now
EDIT: ready for the big news? IT WORKS!
before the reboot, i had about 128MB sdswap on, and 166MB free in the /data partition.
afterr reboot, i now have 197MB swap (which is 128MB + 64MB... + the extra numbers ) and 95MB free in /data...
now with the deletion of some bloat apps (i have about 210 apps) i might get over 100MB free in /data, that way the file could have some space to physically move...
i'll throw my 5 thanks of the day to you now
EDIT: whoa! now with that much extra RAM, i think i should bump up my VM heap size.
EDIT: something weirrd just happened:
while i uninstalled 2 apps (100 floors and its official cheats) i went to check /data's free memory and it showed me 163MB, that's only 3MB "eaten" by the dataswap. so i went to terminal and saw that the total is still 197MB... is it because the file has a "dynamic" size? (meaning it gets larger when it needs to) or is it a constant size... and if it has a constant (64MB) size, what just happened with my /data partition?
———————————————————
i didn't mean to mock you or to offend you in any kind of way
The dataswap file would be a prefixed size, i.e.: if it was created as 64MB it stays as 64MB, what it consumes internally may vary, but its always eating least 64MB of the /data partition.
You could always run something like du -hs /data/*
to see what is using what space.
In other news the swap seems to be maxing out on mimicry (but I wonder if it's because a 1.3GB app is being installed from the play store and is using all the ram and then some), on elitemod it normally wouldn't get higher than 40mb or so.
ok, i confirmed this, no need to test it yourself... it practically works on ILWT as there is not much difference between EMCM7 and ILWTCM7...so you might wanna change OP and put that data swap works on GB... although never tested on sense or MIUI.
i can see it's using it a little bit... i mean i opened root explorer, play store, settings, then tapatalk. and when going back to root explorer it restarted... it didn't keep root explorer cached... is there a way to increase swap caching? i mean if i were android i would start caching in swap until i at least use 75% of it

I think it's going to vary by the app, the swap is only used when memory is being run out of which is the way you want it to work. Swap shouldn't be used as caching per-se, just mainly as a ceiling for when ram is being used up.
I noticed that when using SuperChargerV6 the swap usage is almost nil, but course SuperCharger may prevent apps from multitasking as much.
I think it's a good idea to use the init.d scripts from the CM9 compatible kernel if you didn't. It basically just removes the support for async init.d ordering but should work everywhere even on AOKP. I had to make sure the scripts run in an order for the ROM installation but alone they don't need the syncing code and it reportedly freezes on CM9.
(EDIT, nevermind, it doesn't really matter since this script is the first of the sequence. Still the extra lines are unnecessary)
Also an "OFF" package may be a good idea
The swap usage is due to the tweaks in elitemod_kernel.sh, when the swap gets full it will slow the phone down to a crawl. That's why supercharger causes problems with swap, it overrides something in there.

I'd imagine off for dataswap would simply be your original OFF mod zip, since int wouldn't do anything differently. What would be interesting would be an "off" for sd-ext, which I guess would just be a edify script to move /sd-ext/app and /sd-ext/app-private back to /data and then the removal of the init script.
But yea not all roms are designed to be used with swap storage, those that don't normally have a means of using swap on their own may behave differently when that's introduced into the mix, where as your rom actually has been tweaked with the possibility of using swap in mind.
I still get the best battery life and smoothest swap transfer with EliteMod though. (on mimify for example ,the CPU steps are not as frequent, and is a minimum of 245mhz, with no vdd_levels exposed for undervolting).
Well I wonder if it can be done entirely in recovery. I suppose it's as simple as mounting /data and /sd-ext and copying the data, then wiping /sd-ext. All in one neat flashable package. I guess 4EXT is pretty smart about mount points so it may be as simple as
Code:
run_program("/sbin/busybox", "mount", "/sd-ext");
and maybe not

I would think so too, but course I'd be more concerned about checking to see if /data will be able to contain the apps stored in /sd-ext if someone went past the 1GB size. But ya I was thinking bout it being done completely in recovery, and just removing the init script from /system after the move and wipe has been done to sd-ext.
Could probably even run_program () a small shell script copied to /tmp.
Well even if it was impossible to check free space and filesizes directly from recovery you can still invoke shell scripts and use busybox. Something like
Code:
run_program("/sbin/su", "/tmp/script.sh");
Even do the move from there. And then share the flashable zip
I admit you are most likely better at shell than I am, I don't use desktop linux outside VM.
