Sorry guys, I thought I could handle this, but I just tried to update to Hakuro's new rom, but I think my problem is something else. Let me explain.
I used to have H's Cupcake build and I just wiped, installed the radio, installed the SPL and installed the new firmware. I used a Linux machine for format my 4gb memory card with 3gb fat and 1gb ext2 and I extracted the zip file into its own folder.
I have tried doing an "adb shell ls /system" and it shows there are no files there. Have I lost root access? Is that what would make that folder vanish for me?
if you're booted into recovery, /system isn't mounted.
is that the case?
Ah, yes. I guess I was getting a little over worried about nothing. So at least I don't have to worry about 'that' being the problem of why my phone keeps rebooting.
I can wait until the main thread gets unlocked... Unless anyone wants to share some ideas?

if you didn't wipe, i'd def try that
I did. I expect that doing "adb shell ls /sdcard" should work in recovery, correct?

/sdcard isn't mounted in recovery, either.
if you do:
adb shell
...then...
mount /sdcard
you can read / write to the card just fine
Ahh, I thought a messed up the Apps-SD step. I'm getting a message saying:
"mounting /dev/block/mmcblk0p1 on /sdcard failed: Invalid argument"
Hmm, my Linux machine sees the partitions just fine.
/dev/sdb2 fat32 2.74GiB
/dev/sdb1 ext2 1.00GiB
Both appear to be primary partitions.
I tried doing a "busybox df -h" in ADB and it didn't list my SD card.
I was just curious if anyone would be interested in making a step in the right direction dog such a new device. I have worked with a2sd on several other android phones(most of which already had froyo ported). I also have some experience in porting Roms to other devices. If anyone else that has already bought a flipside, and at least a pretty decent understanding on how the OS works and how to stuff like that. Also... it would be a huge plus if someone has experience in building Roms, as well as dumping them from our devices.
I'm planning on starting off with a clean and fast ROM for our phones... and hopefully with a2sd built in as well, or at least installable.
If you are interested then send me a PM and we can get to work... the sooner the better!
Looking at /proc/filesystems it seems that the stock kernel only has support for yaffs2 and vfat. The stock image doesn't include any .ko files so I'm assuming all of the needed functionality is compiled into the kernel with no support for external module loading.
Using Busybox 1.18 from the Market I can loop mount vfat images without any problem (I had partitioned my SD card under Linux but it seems that init and motobox are hard-coded to load mmcblk0p1 at /sdcard and then it kept unmounting /sdcard randomly when I had extra partitions after it... so loop-mounting is safer without breaking things).
The problem is of course permissions since vfat doesn't support ugo-style permissions. We can't loop mount yaffs2 images since the emulated block device is not NAND flash... and that's also the reason we can't just dd a yaffs2 filesystem into a partition on the SD card.
I'm going to experiment with init.rc a bit and see if I break anything by forcing it to mount /sdcard immediately after /system (because that's where it should be mounting /data). I don't want to run the risk of loop mounting a file from /sdcard onto /data only to have it forcibly unmounted when vold gets enumerated and remounts /sdcard.
It's really unfortunate that there's so little space on the internal memory of this device... /cache is ~140 Mb, /system is ~180 Mb, and /data is ~160 Mb, so even if we were to lean out /system and swap it around with the others, we only get 20 Mb more on /data... that's way too much work for such little gain.
OT - Why is there so much hatred against this device? It's more than fast enough to play Quake 3 and I'd trade all the screen real estate in the world for a hardware keyboard... oh, and the phone actually fits in my pocket (unlike my friend's Droid X which is so huge and unwieldy...). Anyway, I just think it's odd.
Update: It seems that the device checks that boot and recovery images are signed with a Motorola digital certificate at runtime... I can flash the partitions just fine, but it just boot-loops with "Error CC00 DBAD" and then eventually drops back to the bootloader. Unfortunately this means that I can't test any changes to mount points in init.rc at this time. Since I don't have any means to recover the device from a bad bootloader flash, this will have to be the end of the road for me at this time. Some other brave soul will have to experiment with replacing mbmloader or lbl to allow loading custom images signed with test certificates from the SDK.
EDIT: I should mention that I had to use sbf_flash to upload images since fastboot won't work until we have an unlocked bootloader on the device. I wish I had read up on and-developers.com before discovering all of this stuff the hard way. Oh well. Even the ramloader from the SBF image is signed with a Motorola digital certificate so I'm not sure that using sbf_flash (I haven't tried RDSlite, don't have Windows) is the way forward either. I don't think we can just dd the new images for the bootloader either since not all of the MTD partitions are exposed to the OS. This is going to be harder than I expected.
Init.rc executes /system/etc/install-recovery.sh as a privileged user. Lucky for us, this is at the end of the init script once everything is up and running and AT&T/Motorola have removed the file so we don't have to alter anything of value. I've tested it and adding install-recovery.sh will run commands as root. This is our way in.
Hopefully we can get apps stored on the SD card soon.
EDIT: The contents of this post are now deprecated and remain here for historical purposes only! Please see the posts below for the "proper" scripts.
So after playing with it some more, mounting a vfat filesystem on /data simply doesn't work because permissions and ownership can't be set. Even setting the most relaxed permissions possible I found bizarre side effects like apps won't install from the Market and wifi can't be toggled on/off. I found an ext2.ko compiled for the Milestone stock rom (I've attached it here for convenience, but I found it on android-hilfe.de) works just fine though, so now we can use a proper filesystem.
Right now I'm mounting a 512 MB ext2 filesystem onto /data and everything works great. The biggest problem I'm having though is that switching to USB Mass Storage mode forcibly unmounts my filesystem so that obviously causes problems, but I don't really see a way around this since UMS mode offers up the entire MMC device so there's no way to just pick one partition to expose...
I'm going to test more things to make sure nothing has broken before I post a full write up on this, but if you know what you're doing, it shouldn't be hard to figure it out on your own. I know most of the Apps2SD projects are using an application to manage data then setting up a separate partition on the SD card, but it usually relies on some custom recovery image and the goal for me is to do this against a stock rom. I'm also using a loop-mounted filesystem because it makes it easier to migrate to a new SD card without having to worry about partitions and what-not.
EDIT: Here's a quick-n-dirty version for those of you who would like to try it. This will show the proof of concept and let you see if it works for you without breaking anything major. All changes to /data will be undone on the next reboot. If you know what you're doing, then I would recommend making the changes permanent by mounting /data in install-recovery.sh. This is assuming you have rooted your phone (I used z4root) and have Busybox installed (I used 1.18 from the Market) and at least 512 MB free on your SD card.
Code:
adb push ext2.ko /sdcard
adb shell
su -
/system/bin/busybox mount -o rw,remount /system
/system/bin/busybox cp /sdcard/ext2.ko /system/lib/modules
/system/bin/busybox chown 0.0 /system/lib/modules/ext2.ko
/system/bin/busybox chmod 0644 /system/lib/modules/ext2.ko
/system/bin/busybox mount -o ro,remount /system
/system/bin/busybox insmod /system/lib/modules/ext2.ko
/system/bin/busybox dd if=/dev/zero of=/sdcard/userdata.ext2 bs=1M count=512
/system/bin/busybox losetup /dev/block/loop0 /sdcard/userdata.ext2
/system/bin/busybox mkfs.ext2 /dev/block/loop0
/system/bin/busybox mount -o rw,remount /
/system/bin/busybox mkdir /userdata
/system/bin/busybox mount /dev/block/loop0 /userdata
/system/bin/busybox chown 1000.1000 /userdata
/system/bin/busybox chmod 0771 /userdata
cd /data
/system/bin/busybox cp -r -f -H -p . /userdata
cd /
/system/bin/busybox umount /userdata
/system/bin/busybox rmdir /userdata
/system/bin/busybox mount -o ro,remount /
/system/bin/busybox umount -l /data
/system/bin/busybox mount /dev/block/loop0 /data -o rw,sync,nosuid,nodev,noatime,nodiratime
If you've done everything right, "lsmod" and "cat /proc/filesystems" will show "ext2", "mount" will show /dev/block/loop0 on /data, and "df" will show more space available on /data. You should also see the extra space in Settings -> SD card & phone storage -> Internal phone storage.
My install-recovery.sh currently looks like this:
Code:
#!/system/bin/sh
if [ -e /system/lib/modules/ext2.ko ] && [ "`/system/bin/busybox lsmod | /system/bin/busybox grep -c ext2`" -eq "0" ]
then
/system/bin/busybox insmod /system/lib/modules/ext2.ko
fi
# wait 30 seconds, /sdcard is being re-mounted by vold...
/system/bin/busybox sleep 30
if [ -s /sdcard/userdata.ext2 ] && [ "`/system/bin/busybox cat /proc/filesystems | /system/bin/busybox grep -c ext2`" -eq "1" ]
then
/system/bin/busybox losetup -d /dev/block/loop0
/system/bin/busybox losetup /dev/block/loop0 /sdcard/userdata.ext2
/system/bin/busybox umount -l /data
/system/bin/busybox mount /dev/block/loop0 /data -o rw,sync,nosuid,nodev,noatime,nodiratime
fi
You don't have to use this as-is, but it's at least a starting point.
UPDATE: Seems like we need a Busybox with a proper tune2fs utility as the one in the Market is pretty useless (only changes volume labels...). You'll want to run "tune2fs -c 0 -i 0 /dev/block/loop0" to disable mandatory fsck'ing, otherwise the kernel will reject the mount after a few times because it's dirty. Something funky is happening because any apps that I install once the image is mounted will not show up after reboot, but the files are there and they continue to take space. Maybe I'm breaking something with the lazy umount?
At the risk of sounding like I'm only talking to myself, I'll post another update...
I found that most of my troubles were stemming from waiting so long to remount /data, so I caved and put an ext2 partition on my SD card so that I don't have to wait 30 seconds before mounting over /data.
Oddly enough, mounting a native ext2 partition for /data from the SD card was actually MUCH slower than the loop mounted image. I should note that I'm not mounting the partition with the 'sync' option. I could get away with that on the loop device since it's just doing it in memory anyway and changes are only being written on the default commit interval for the host filesystem. Anyway, I'm using a 4 GB class 10 SD card, but it's still much slower than the internal flash. Just to confirm my results, I tried with a native ext2 partition on a 2 GB class 2 SD card... the phone took nearly 5 minutes finish booting to a responsive home screen!
But, at least I can mount /data right away when I'm using a physical partition... So I've done the best of both worlds by creating a ext2 partition on my SD card and then loop mounting an ext2 image onto /data. The result: I'm running my entire /data on a class 2 SD card and it's much faster than a native partition on a class 10! In fact, the difference in boot time compared to internal storage is only a few seconds! Now that I'm mounting /data right away I no longer have problems with missing apps or data after reboots. The only drawback is that you have to waste a bit of space to do it this way since the filesystem reserves 10% for itself, you need a 560 MB partition to hold a 512 MB image (in my case I'm actually running a 384 MB image since I don't really need that much space anyway). Personally, I don't mind since I'm running it off of a cheapo class 2 device and having everything in a single image file makes it super simple to migrate to a different SD card if I want to.
I'll keep running this setup for a couple days now to make sure that there's nothing else broken, but for right now I've got it setup just how I want it: no extra application to manage which apps are where and no random force closing from applications running off of SD card that weren't meant to be. Oh yeah, and I don't have to worry about dalvik-cache cannabilizing my internal storage either.
If anyone else is following along, I'd like to hear your experiences with this too. I'll post the final write-up once I'm certain that nothing else is broken.
I'm definitely following along appreciatively, but will have to wait for the step by step to give it a try.

Well, here is the much-awaited write-up...
First, acknowledgements. This would not have been at all possible without the ext2 module provided by user Fnordi on android-hilfe.de. Unfortunately I can't read German so I have no idea if he actually compiled it for the Milestone or somebody else did, but I grabbed the file from his post about loading Debian Linux on the Milestone, so kudos to him and whomever else was involved. I also wouldn't have been able to write this up so neatly without the sdparted script by 51dusty. I had to make a few alterations because we're not running on CyanogenMod Recovery, but it's still mostly his work nonetheless. The parted and tune2fs binaries are from j_r0dd's Recovery image for the Motorola Backflip. Also, cheers to the folks on android-dls.com wiki, even though the information is mostly targeted at the G1 and ADP, it was still very good reading.
WARNING WARNING WARNING
I have not yet devised a way to migrate the SD card data back to internal storage! Once you've migrated /data to the SD card, anything new from that point forward will stay on the SD card. Additionally, I will not be providing support for anyone who deviates from the process outlined here. If you're clever enough to do it some other way, then you're clever enough to get out of trouble on your own. Do this at your own risk, I am not responsible for any harm or loss of data that may occur as a result of following this procedure. You have been warned!
WARNING WARNING WARNING
Requirements: Android SDK installed with working ADB, root access on your Motorola Flipside and Busybox 1.18 installed from the Market. There is plenty of information available on the forum on how to do these things so please don't post here asking how to root the phone. The assumption is that you know how to gain root access and that you're comfortable with ADB. If you're struggling with doing any of these things, then you should reconsider if you want to attempt this at all.
1. Backup your SD card and format it so that it's completely clean and has only a single, empty, FAT32 partition on it.
2. Grab the attached ZIP file and extract the files directly into the SD card (no sub-folders). Make sure these are the only files on there, everything else will be erased!
3. Set your phone's USB connection to "Charge Only".
4. Connect via ADB using "adb shell".
5. Now run the following:
Code:
su -
cp /sdcard/setup.sh /data/local
/data/local/setup.sh
6. The script will now setup a 512MB partition on your SD card with a 448MB image for /data. All of the other data on your SD card will be lost!
7. After the script is finished, restore any files that you backed up before to the FAT32 partition of your SD card.
8. Set your phone's USB connection to "Charge Only" and never change it again!
9. You should now have a lot more space for apps!
Please note that the phone will feel a little sluggish for a little bit after boot, but soon it will have everything buffered in memory and it will feel very smooth again.
Enjoy!
EDIT: I should mention, if you want to undo the changes, either shut down the phone and remove the SD card or delete /system/etc/install-recovery.sh. Either way, the phone will revert back to internal storage automatically on the next boot.
EDIT 2: I noticed that the Market install of Busybox doesn't link any existing commands, only new ones. I've been using the 1.18 binary from the Market but I had used my own script to link everything properly (mostly to replace "sh" since no tab completion was killing me!). I've now included the install script in the zip. So install the Busybox 1.18 from the Market, then run my install-busybox.sh, then reboot and follow the instructions above. Sorry for the mix-up!
Alright, just making sure. You're last Edit:, you said that we have to run your "install busy-box.sh". To run it, is it in the script in your post above, or is there some other way? I'm pretty new to runnin' all these scripts since I'm on a Captivate which is far easier than this (I'm doin' this for my girlfriends Flipside).
Just in general, what are the steps you run your install busy-box?
Thanks ahead of time.
thank!!!!!!!
can anybody help me do this because when i do it at the bottom it says failed
You leave it on "Charge Only" because otherwise it will unmount the /data image and cause it to crash.
This was stated previously in my posts. Please read carefully next time.

1. Install Android SDK on your computer.
2. Hook up via ADB and install z4root.
3. Run z4root on your phone. It will root the phone and reboot.
4. Install Busybox from the Market.
5. Copy the contents of the zip file to your SD card.
6. Log in as root via ADB ("adb shell" then "su -").
7. busybox mount -o rw,remount /system
8. cp /sdcard/install-busybox.sh /data/local
9. busybox sh /data/local/install-busybox.sh
10. reboot
11. Log in as root via ADB ("adb shell" then "su -").
12. ls -la /
If everything is done properly, the last step should result in an expanded directory listing in a color terminal. You can now proceed with the rest of the tutorial.
ok after i reboot i got look at my phone storage and it is still the same it didnt increase or anything
the method you've presented here sounds interesting, but i'd really hate to lose the memory card access function of my phone (i use it quite often...very often in fact). so i have a question or two:
would it be possible to get a bigger sdcard(say a 4GB or 8GB sdcard), and dd my current sdcard's partition to the new card, and then create another partition on the rest of the new card and have this method utilize that new partition in the manner described here? would the entire sdcard still get unmounted if i set the phone to memory card access?
<edit>: never mind...it seems this question would be answered by: "The script will now setup a 512MB partition on your SD card with a 448MB image for /data".....so apparently yes the sdcard would still be unmounted :/

I backed up my sdcard and copied the files over. I have busybox and it is rooted.
I accessed superuser and copied the files over per the write-up.
When I ran setup.sh, it gave me the following error:
----

I understand that it is a read only error, but not sure how to edit the script (or if I even need to) to get it to work. It looks like the first line of the script remounts the system properties to -rw, but it still failed to write.
Hi all, originally intending to post this tutorial to Ideos S7 Android Development but got a nice greeting from xda-developers.com unallowing newbies to post there
So I just got a brand-new-in-a-box, dead cheap, Ideos S7 tablet -- my first android tablet, and my second android device. I brought my last device about 2 years ago, a G1 that I only kept for a week and sold it afterwards. I was thinking that at that time Android isn't ready yet for replacing my E71.
Back to the Ideos S7, mine is already preloaded with TRZ-mod-0.2 ROM, which is nice. However, I had some issue with wireless network. Whenever I disable my wifi, I would ge trouble activating it as it constantly disabled by itself. Thus, I decided to go back to available stock ROM. Long story short, I've chosen the Froyo 2.2.2 Sweden coded S7V100R001C63B110, and made myself comfortable with repeating Huawei's flashing process.
The firmware seems more stable, and does not have the wireless network activation/deactivation issue. Stock ROM lover anyone
However, the stock ROM doesn't have apps2d+ or whatever that was called, to extend the internal storage. 137MB of free space is really pity for such device. I couldn't run Data2Ext* script successfully, as the default shell /system/bin/sh doesn't seems to support square brackets on scripts conditional parts. Busybox 1.18 supports it, but somehow it would cause all the commands executed in the script to ran by Busybox, causing "applet not found" errors. The other option would be Link2SD, which could probably saved me 10+ hours of hacking. It had its drawback though, the current version on the market expects the extended internal tablet storage partition to reside on the external SD card. Some hacking to mount the internal SD partition works, but not sure whether it would got correctly mounted on boot.
Also, the most important thing: nothing feels better than looking at "Available space" on "Internal tablet storage" of 5.5GB
So here it is, the tutorial for extending the internal storage. Most of the information used are gathered from various sources, and rewritten here for your enjoyment!
REQUIREMENTS:
=========
a) All hardware: Ideos S7 -- should work on Slim as well, data cable, charger, a living being..
b) Rooting -- I've used Gingerbreak from the market
c) Terminal Emulator -- Android Terminal Emulator works fine. Irritating blue background though.
d) Busybox -- 1.18 version is working fine
e) Root explorer -- Optionally used, for easier file editing and copying.
STEPS:
=========
0) Backup your data, as all data in internal storage will be lost!
---------
Well honestly I didn't do this as I got my contacts and mail synced on the internet. My S7 only got 5 days of lifetime so not much data there yet. Sorry no guide on how to do this
1) Partition the internal SD (or external SD card if you intend to do so).
---------
It is recommended to use a good class of memory card when using external SD card for the tablet storage partition.
There's possibly partitioning tools available for the architecture, but I did it with EASUS Partition Master on a Windows system. Mac OS's Disk Utiliy should work as well. Don't worry too much about the partition type, we'll reformat it later with busybox later anyway.
To partition the internal (or external) SD card, connect your data cable to your phone. When the USB connection notification came up, activate the USB storage mode. You don't need to install the Huawei S7 (or adb) drivers.
Fire up your partitioning application, and identify your storage. Delete (or) resize the existing FAT partition. Create another primary partition afterwards, with ext2 filesystem. ext3 and ext4 isn't supported in the stock ROM, so you probably have to either install a kernel module for the ext3,4 or replace your boot.img. Hey but that's not going to be a stock ROM
2) Root the device
---------
Install Gingerbreak from the market. Enable USB debugging in Settings -> Application -> Development, or else it won't work. Run Gingerbreak, root your device! The device will restart after successful process, and you are ready to modify your root filesystem.
3) Prepare the required tools
---------
You'll optionally need busybox to format and edit the files. Copy over the busybox binary file to /system/xbin/. The terminal login path would automatically points there so you can run busybox from anywhere inside the terminal.
4) Prepare the new data directory
---------
Fire up your terminal emulator. You'll need to be logged in as root to do the whole operation mentioned. Thus, type in:
Code:
su
Mount the new partition you've prepared on step (1). For internal SD, it's going to be /dev/block/mmcblk0p2 device, or for external SD, /dev/block/mmcblk1p2. You can also use other shorthand such as /dev/block/vold/179:2. But for simplicity, I'll use mmcblk*p* throughout the tutorial.
Prepare the mount point for your prepared data partition, and mount it. If it's currently mounted, unmount it first.
Code:
umount /dev/block/mmcblk0p2
mkdir /system/sd
You can also format the partition now if you didn't specify the partition type during the partition creation.
Code:
busybox mke2fs -m0 -b4096 /dev/block/mmcblk0p2
Now mount the extended data partition.
Code:
mount -t ext2 /dev/block/mmcblk0p2 /system/sd
We'll still need to be able to access the original data partition now and later, so, prepare the mount point and mount it as well.
Code:
mkdir /system/internal
mount -t yaffs2 /dev/block/mtdblock4 /system/internal
At this stage, you'll need to copy over all files inside the original /data directory to your new sd directory. You'll also need to make sure that the permissions isn't changed during the process. To do this, just tar the entire original data directory to your new one.
Code:
cd /system/internal
busybox tar -cvf /system/sd/old-data.tar *
cd /system/sd
busybox tar -xvf old-data.tar
busybox rm old-data.tar
The initialization for the new data directory mounting in the boot process does not modifies the boot image's init.rc. Thus, it seems that the initialization process is called after the radio initialization. I can't get my GSM to work without this step. We'll need to symbolic-link back the /system/sd/radio directory to the original internal storage /data/radio directory. And remember that on the boot process, we'll need to mount /system/internal *before* /system/sd.
Code:
cd /system/sd
busybox rm -rf radio
ln -s /system/internal/radio /system/sd/radio
After fiddling for several hours, I realized that the date and time settings gets reset on each boot. Fixed by symlinking the /data/date.time back to the internal storage.
Code:
cd /system/sd
busybox rm -rf date.time
ln -s /system/internal/date.time /system/sd/date.time
5) Prepare the boot init script
---------
The Froyo boot process runs init.rc script, which is replaced by the boot.img when system boots. So we can't put our new /data directory mount commands there, unless we extract, unpack, modify, repack the boot.img. Ok so I decided that modifying boot.img will be the last step if I can't get it working without it. There must be an easier way!
Also, there aren't any rc.d, rc3.d, bla bla directory in which we can put our custom initialization script.
Luckily, there is a script that is called from the init.rc script during boot, which is stored on the root filesystem and can be customized. It's called /system/etc/install-recovery.sh. Thus, we'll put the initialization script there. If you already got a /system/etc/install-recovery.sh, you can just add our initialization script in the beginning of the. Alternatively, you can create a separate script to perform init, and call it from your modified /system/etc/install-recovery.sh.
There will be drawback, for example, it seems that the script is called after radio initialization, so we'll need to use the old /data/radio directory from the original /data directory, prepared on step (4).
So now you'll need to create (or copy) the install-recovery.sh script. You can use vi from the busybox, or easier is to just copy and paste the install-recovery.sh script provided in this post. In case you're a vi expert, fire up these commands. Don't forget to remount the root filesystem as rw first!
Code:
busybox vi /system/etc/install-recovery.sh
Write in the install-recovery.sh script:
Code:
#!/system/bin/sh
mount -t yaffs2 /dev/block/mtdblock4 /system/internal
mount -t ext2 /dev/block/mmcblk0p2 /system/sd
mount -o bind /system/sd /data
Don't forget to set executable and readable attribute at least for root user, or else the system can't run the script!
Code:
chmod 755 /system/etc/install-recovery.sh
So now you're ready to reboot the system. Double check the install-recovery.sh script, make sure all commands mounts the partition exactly to where you intend it.
6) Reboot your Ideos S7!
---------
Reboot and enjoy the trendemous increase on your internal tablet storage
WARNING!!! Do not attempt to perform factory data reset while running with /data mounted. It seems that S7 will format the /data partition as yaffs2, not sure as I haven't checked it. But it worth to try to change the install-recovery.sh script to mount the data partition as yaffs2, and then performing factory data reset.

Should've post the title with [HOWTO] prefix. Sorry about the newbie-ish thing
Hey, sure i can post them! I've set up a site for the "Install GNU/Linux" anyway. I'll be looking to follow this howto sometime in the future. Tell ya what tho, i'd have saved 10+ hours hacking had i known gingerbreak was in market also!

Nice guide
work perfectly on S7 slim
i do all the steps using sshdroid and putty so i can use cut&paste from web page
the only think that i've to add is mount syster as readwrite:
mount -o rw,remount -t yaffs2 /dev/block/XXXXXXX /system
Thanks for this guide i will do the same on all my device
i'm triing to increase internal memory on stock rom.
I successfully done on S7 slim (i found i guide writen by watch_mania) but on Vodafone Smart i've some trouble (i use sshdroid and putty).
I do the following step :
1) Partiton the external SD with two filesystem the the first one FAT32 the second one ext2
this is the output of fdisk :
/system/sd # fdisk -l /dev/block/mmcblk0 Disk /dev/block/mmcblk0: 7969 MB, 7969177600 bytes
255 heads, 63 sectors/track, 968 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System
/dev/block/mmcblk0p1 1 509 4088511 83 Linux
/dev/block/mmcblk0p2 510 968 3686917+ b Win95 FAT32
2) mount system as read-write and create new mount point
mount -o rw,remount -t yaffs2 /dev/block/mtdblock4 /system
mkdir /system/sd
mkdir /system/internal
3) format ext2 partition created at 1)
mke2fs -m0 -b4096 /dev/block/mmcblk0p1
4) mounting the "original" /data on /system/internal and new ext2 partition on /system/sd
mount -t yaffs2 /dev/block/mtdblock6 /system/internal
mount -t ext2 /dev/block/mmcblk0p1 /system/sd
5) copy the content on "original" /data on /system/sd
cd /system/internal
tar -cvf /system/sd/old-data.tar *
cd /system/sd
tar -xvf old-data.tar
rm old-data.tar
6) create boot init script
vi /system/etc/install-recovery.sh
and write inside :
#!/system/bin/sh
mount -t yaffs2 /dev/block/mtdblock6 /system/internal
mount -t ext2 /dev/block/mmcblk0p1 /system/sd
mount -o bind /system/sd /data
Originally in the guide for S7 slim you have to do :
cd /system/sd
rm -rf radio
ln -s /system/internal/radio /system/sd/radio cd /system/sd
rm -rf date.time
ln -s /system/internal/date.time /system/sd/date.time
BUT if i try to do that the device does not recognize the sim.
If i try to don't do that the device loop during boot.
on S7 Slim in /system/internal/radio i found this file :
srwxrwxrwx 1 0 0 2048 Dec 31 06:49 qmux_connect_socket
the same file on vodafone smart is located in /system/internal/local/tmp/
but if i try to link it does not work and the device loop.
Will this also work on altek A14 LEO(an Android 2.1 phone)? It has less than 100MB internal storage, although it built-in dtapps2sd with the newest stock firmware, "/data/data" is still stored in internal storage. Because the version of dtapps2sd in stock firmware is not latest version, no "/data/data" mount on SD-EXT support. And I can't upgrade dtapps2sd myself due to no reflash tool for this phone.
Thank for the niec post, i,ll try it shortly
Increasing Internal Memory
Hi,
Has anyone tried a superb "setinstalllocation-xxx.apk" available in xda-developers.
I have been using it and it is really good. But as mentioned by watch-mania that 139 or 140 MB of available storage is a pity.
Your device must be rooted to use the above apk. You can successfully use gingerbreak available from this excellent forum.

Hi all, originally intending to post this tutorial to Ideos S7 Android Development but got a nice greeting from xda-developers.com unallowing newbies to post there
So I just got a brand-new-in-a-box, dead cheap, Ideos S7 tablet -- my first android tablet, and my second android device. I brought my last device about 2 years ago, a G1 that I only kept for a week and sold it afterwards. I was thinking that at that time Android isn't ready yet for replacing my E71.
Back to the Ideos S7, mine is already preloaded with TRZ-mod-0.2 ROM, which is nice. However, I had some issue with wireless network. Whenever I disable my wifi, I would ge trouble activating it as it constantly disabled by itself. Thus, I decided to go back to available stock ROM. Long story short, I've chosen the Froyo 2.2.2 Sweden coded S7V100R001C63B110, and made myself comfortable with repeating Huawei's flashing process.
The firmware seems more stable, and does not have the wireless network activation/deactivation issue. Stock ROM lover anyone
However, the stock ROM doesn't have apps2d+ or whatever that was called, to extend the internal storage. 137MB of free space is really pity for such device. I couldn't run Data2Ext* script successfully, as the default shell /system/bin/sh doesn't seems to support square brackets on scripts conditional parts. Busybox 1.18 supports it, but somehow it would cause all the commands executed in the script to ran by Busybox, causing "applet not found" errors. The other option would be Link2SD, which could probably saved me 10+ hours of hacking. It had its drawback though, the current version on the market expects the extended internal tablet storage partition to reside on the external SD card. Some hacking to mount the internal SD partition works, but not sure whether it would got correctly mounted on boot.
Also, the most important thing: nothing feels better than looking at "Available space" on "Internal tablet storage" of 5.5GB
So here it is, the tutorial for extending the internal storage. Most of the information used are gathered from various sources, and rewritten here for your enjoyment!
REQUIREMENTS:
=========
a) All hardware: Ideos S7 -- should work on Slim as well, data cable, charger, a living being..
b) Rooting -- I've used Gingerbreak from the market
c) Terminal Emulator -- Android Terminal Emulator works fine. Irritating blue background though.
d) Busybox -- 1.18 version is working fine
e) Root explorer -- Optionally used, for easier file editing and copying.
STEPS:
=========
0) Backup your data, as all data in internal storage will be lost!
---------
Well honestly I didn't do this as I got my contacts and mail synced on the internet. My S7 only got 5 days of lifetime so not much data there yet. Sorry no guide on how to do this
1) Partition the internal SD (or external SD card if you intend to do so).
---------
It is recommended to use a good class of memory card when using external SD card for the tablet storage partition.
There's possibly partitioning tools available for the architecture, but I did it with EASUS Partition Master on a Windows system. Mac OS's Disk Utiliy should work as well. Don't worry too much about the partition type, we'll reformat it later with busybox later anyway.
To partition the internal (or external) SD card, connect your data cable to your phone. When the USB connection notification came up, activate the USB storage mode. You don't need to install the Huawei S7 (or adb) drivers.
Fire up your partitioning application, and identify your storage. Delete (or) resize the existing FAT partition. Create another primary partition afterwards, with ext2 filesystem. ext3 and ext4 isn't supported in the stock ROM, so you probably have to either install a kernel module for the ext3,4 or replace your boot.img. Hey but that's not going to be a stock ROM
2) Root the device
---------
Install Gingerbreak from the market. Enable USB debugging in Settings -> Application -> Development, or else it won't work. Run Gingerbreak, root your device! The device will restart after successful process, and you are ready to modify your root filesystem.
3) Prepare the required tools
---------
You'll optionally need busybox to format and edit the files. Copy over the busybox binary file to /system/xbin/. The terminal login path would automatically points there so you can run busybox from anywhere inside the terminal.
4) Prepare the new data directory
---------
Fire up your terminal emulator. You'll need to be logged in as root to do the whole operation mentioned. Thus, type in:
Code:
su
Mount the new partition you've prepared on step (1). For internal SD, it's going to be /dev/block/mmcblk0p2 device, or for external SD, /dev/block/mmcblk1p2. You can also use other shorthand such as /dev/block/vold/179:2. But for simplicity, I'll use mmcblk*p* throughout the tutorial.
Prepare the mount point for your prepared data partition, and mount it. If it's currently mounted, unmount it first.
Code:
umount /dev/block/mmcblk0p2
mkdir /system/sd
You can also format the partition now if you didn't specify the partition type during the partition creation.
Code:
busybox mke2fs -m0 -b4096 /dev/block/mmcblk0p2
Now mount the extended data partition.
Code:
mount -t ext2 /dev/block/mmcblk0p2 /system/sd
We'll still need to be able to access the original data partition now and later, so, prepare the mount point and mount it as well.
Code:
mkdir /system/internal
mount -t yaffs2 /dev/block/mtdblock4 /system/internal
At this stage, you'll need to copy over all files inside the original /data directory to your new sd directory. You'll also need to make sure that the permissions isn't changed during the process. To do this, just tar the entire original data directory to your new one.
Code:
cd /system/internal
busybox tar -cvf /system/sd/old-data.tar *
cd /system/sd
busybox tar -xvf old-data.tar
busybox rm old-data.tar
The initialization for the new data directory mounting in the boot process does not modifies the boot image's init.rc. Thus, it seems that the initialization process is called after the radio initialization. I can't get my GSM to work without this step. We'll need to symbolic-link back the /system/sd/radio directory to the original internal storage /data/radio directory. And remember that on the boot process, we'll need to mount /system/internal *before* /system/sd.
Code:
cd /system/sd
busybox rm -rf radio
ln -s /system/internal/radio /system/sd/radio
After fiddling for several hours, I realized that the date and time settings gets reset on each boot. Fixed by symlinking the /data/date.time back to the internal storage.
Code:
cd /system/sd
busybox rm -rf date.time
ln -s /system/internal/date.time /system/sd/date.time
5) Prepare the boot init script
---------
The Froyo boot process runs init.rc script, which is replaced by the boot.img when system boots. So we can't put our new /data directory mount commands there, unless we extract, unpack, modify, repack the boot.img. Ok so I decided that modifying boot.img will be the last step if I can't get it working without it. There must be an easier way!
Also, there aren't any rc.d, rc3.d, bla bla directory in which we can put our custom initialization script.
Luckily, there is a script that is called from the init.rc script during boot, which is stored on the root filesystem and can be customized. It's called /system/etc/install-recovery.sh. Thus, we'll put the initialization script there. If you already got a /system/etc/install-recovery.sh, you can just add our initialization script in the beginning of the. Alternatively, you can create a separate script to perform init, and call it from your modified /system/etc/install-recovery.sh.
There will be drawback, for example, it seems that the script is called after radio initialization, so we'll need to use the old /data/radio directory from the original /data directory, prepared on step (4).
So now you'll need to create (or copy) the install-recovery.sh script. You can use vi from the busybox, or easier is to just copy and paste the install-recovery.sh script provided in this post. In case you're a vi expert, fire up these commands. Don't forget to remount the root filesystem as rw first!
Code:
busybox vi /system/etc/install-recovery.sh
Write in the install-recovery.sh script:
Code:
#!/system/bin/sh
mount -t yaffs2 /dev/block/mtdblock4 /system/internal
mount -t ext2 /dev/block/mmcblk0p2 /system/sd
mount -o bind /system/sd /data
Don't forget to set executable and readable attribute at least for root user, or else the system can't run the script!
Code:
chmod 755 /system/etc/install-recovery.sh
So now you're ready to reboot the system. Double check the install-recovery.sh script, make sure all commands mounts the partition exactly to where you intend it.
6) Reboot your Ideos S7!
---------
Reboot and enjoy the trendemous increase on your internal tablet storage
WARNING!!! Do not attempt to perform factory data reset while running with /data mounted. It seems that S7 will format the /data partition as yaffs2, not sure as I haven't checked it. But it worth to try to change the install-recovery.sh script to mount the data partition as yaffs2, and then performing factory data reset.

can you make a video about how increase the internal memory? i trying but at final step after restart my ideos nothing happens, or screenshots, please i have 4 for weeks looking for a solution about the low memory on my ideos, i install joenilan rom but dont like me the launcher, please and sorry for my bad english.
This is one good tutorial that I missed
Sent from my Ideos S7 using XDA App
HELP
Hi, i followed the steps, and my ideos keep looping at the ideos start screen

Reflash with new program,search it ..
My way !
My device : Huawei S7-105
Another way to increse internal memory :
1 flash with stock rom 2.2.2 norvegian
2 flash trizetmod v3
3 with MiniTool Partition Wizard Home Edition i've made 3 partitions on internal memory ( s7-105 using mass storage options )
- 1.2 Gb fat32
- 6 Gb ext4
- 157 Mb swap linux partition
This was one of many attempts to increase memory , and at the end i was happy with that result ! I think that you can make your own partitions , as you wish ! I have seen many movies on youtube .
Most important thing to remember : first you create fat32 partition and make it primary , second is ext4 partition also primary and the last swap partition !
After you create the partitions , reboot in recovery and make a factory reset , and your S7 has 6Gb program memory !!!!!!
Another important thing : I am a newbie in " Android world " , so I do not know how correct is what I did but one thing is certain : I HAVE 5.28 Gb and I got rid of that annoying message LOW MEMORY !!!!!!
I hope I posted in the right place , so i ask an admin to check ! Thx
in summary of this post..
all you have to do is to backup ur current rom via cwm by goodane..
make a 2nd primary partition formatted ext2/ext4 (for ext2 supports 2GB or less.. ext4 for 2GB or higher)
flash trizet's v3 rom
-THE END :good:
Hello guys!
I have a Huawei Ideos S7 Slim too,
Specifications
- Model: Huawei Ideos S7 Slim
- Version: 202u
- Intermal memory: 160 mb
I'm trying to do the steps to increase the internal memory
I don't getting success with the process
I wonder if the process works with the model Huawei Ideos S7 Slim 202u
Thank you
Hello there
I was wondering, can the internal sd card can be mounted with CWM?
If so, can you provide the button count to do it?
I have a S4 with a broken LCD, and I want to retrieve the data, but since I can't enter the passcode, not kies or windows see the files.
I managed to root it and flash CWM but now I got stuck and I just don't remember if I can't mount the internal SD with CWM

install android sdk if you dont have it.
boot your phone into cwm and connect to pc.
open cmd line where adb file exist, and type:
Code:
adb devices
you must see your serial number with recovery
Code:
adb pull /sdcard/ /sdcard/
when it finish, "sdcard" folder in "c" directory

So, after some struggling with the adb drivers I got the device detected by adb and gave this a try, but I think I hit another wall.
sdcard showed 0 files, so I entered the shell and realized the sdcard was not mounted.
I tried to mount it by running mount /sdcard/ but it says sdcard can't be found in fstab{
This is what my fstab has:
cat fstab
/dev/block/mmcblk0p19 /cache ext4 rw
/dev/block/mmcblk0p21 /data ext4 rw
/dev/block/mmcblk0p20 /system ext4 rw
Any suggestion? Thanks in advance
EDIT: I'm thinking that maybe CWM didn't flash correctly (I did it from Odin, and since I'm going blindly there is no way for me to know for sure)

I did. That's when it said that /sdcard/ coudn't be found in /etc/fstab
****************************
UPDATE
I got it to work.
If anyone is interested, this is how I mounted the sdcard
Code:
mount /dev/block/mmcblk0p21 /sdcard/
where mmcblk0p21 is the partition that sdcard usually mounts.
After that, it was a simple as exiting the shell and run
Code:
pull /sdcard/ /sdcard/
as recommended above
I've been searching through various forums, but I cannot find any answers. I'm hoping someone can just lay it out straight or help me out. Is it possible to mount any other MicroSD partition types besides F32? I keep getting trolled by the file size limit when I'm transferring movies and some of the things out there to get ext4 formatted and mounted are not working for me. Am I limited by what development currently has available or does another partition type actually work and I missed it?

yes,
create the directory you will mount in
mkdir -p /sdcard/toasty
then mount the partition, for this example an ext2 partition which correspond to the 2nd partition on your external sdcard
mount -o rw -t ext2 /dev/block/mmcblk1p2 /sdcard/toasty
you plan on using the partition/device normally so mount it read/write, -o rw
your stock kernel needs to support the filesystem type, in this case -t ext2
your stock kernel should support, ext2/3/4 vfat and exfat
ntfs likely requires you compile a custom kernel enabling ntfs support and maybe samba/cifs
wether or not you also need to assign extended attribute support or not, i don't know
you may also need to set selinux toggle support for permissive mode as well
mounting a non-sparse img works similarly
using peanut-butter.img as an ext4 image as the example image and super_yummy as the dir to mount to
mount -o rw -t ext4 /sdcard/peanut-butter.img /sdcard/super_yummy

I have busybox installed and had to use "busybox mount..." to get it to mount. After typing "mount" I see it in the list, but using a file explorer to browse to that directory shows it as empty. I placed a few files in there to ensure I'd see it if it worked correctly, but nothing.

try total commander, the thing is kk perms and selinux make things a royal pain in the [BLEEP]
after you mount, ls the newly mounted partition and see if it's contents display correctly
so if you mounted blah-bity-blah-whatever to /hey/nah-nah then
ls /hey/nah-nah/
if things show up proper copy a file to /hey/nah-nah/ via terminal
cp /sdcard/shmoopy.txt /hey/nah-nah/shmoopy.txt
then ls /hey/nah-nah/ again to see if it showed,
i may have an older version of total commander lying around somewhere.

hmm okay try this, this is a version of my mount script for my debian chroot i run on my tab
note - replace god-awful silliness with actual names ! :silly:
place this script in xbin and run when needed
Code:
#!/system/bin/shell
busybox mount -o rw,remount /
busybox mount -t ext4 -o rw /dev/block/mmcblk1p2 /rooty-tooty
chmod 755 /rooty-tooty
try that, name the script whatever you want and make it executable after copying to xbin
chmod 755 /system/xbin/whatcha-ma-hoozit.sh
you may need to tinker with it a little and also adjust for correct filesystem

@DemisesAngel
TYPO- should be #!/system/bin/sh

That didn't seem to help either. I've been looking over this thread, made some modifications, but I'm still unable to get it to mount correctly. I know I've got the right partition because I can see it from the output, but it still fails.
D,
hi,
Yep, i'm getting the same result, access via terminal, none by apk = most likely /system/etc/permissions/platform.xml
i don't see it being vold, were that the case, we wouldn't be able to access the mounted partition even by terminal.
Maybe by replicating internal storage mounting process, using fuse would work?
I'll try an experiment, does ES explorer have any advanced options for mounting storages or
just the same kid-glove android crap?
The last time this work correctly for me, i was running @starlightknight 's cm11 release for the sm-t530nu and it all
came together quite nicely, which is why i think platform.xml

you can mount system-wide with the debuggerd trick, but its sucks a little.
iam try to adapt vorcers mod.
D,
hi , if you are still having trouble you can try the approach outlined here
