-repeatedly bangs head against wall-
follow this guide but in the beginning where it says use adb and type adb shell
just be in recovery console and hit enter then from there out all the commands should be the same.
if you need more help pm me and i will walk you through the steps

cant; do itr without adb ??

turn phone off and boot into recovery via home+red key
go to console and type in
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# cd /system/sd
# rm -rf /system/sd/*
# reboot recovery
this has been covered many times in many other threads
NOTE:dont type in the # signs. but do however type in the * sign.

go to recovery console hit enter
parted /dev/block/mmcblk0
print
the fourth line in the 'print' command output shows you the total size of sdcard in MB(or GB if you card is large)..mine says: Disk /dev/block/mmcblk0: 7969MB
use this number(XXXXMB) and do some simple math to get the size of your partitions.
7969MB - 32MB linux-swap = 7937MB
7937MB - 500MB ext2 = 7437MB fat32
32MB seems to be alright size for swap, though it can be lower depending on your sdcard size.
500 MB is a good round number for the ext2 partition...no need for more.
that leaves us with 7437MB for fat32 storage.

if you do not want linux-swap then do not figure it in
after figuring out the size of your partitions from using the above method type rm 1 (if you only have one partition skip next part) then rm2
then to make the partitions type (numbers are from above example substitute your own in)
mkpartfs primary fat32 0 7437
mkpartfs primary ext2 7437 7937
mkpartfs primary linux-swap 7937 7969 (only if you want linux-swap)
then type print again to see if it worked. if it did you will have 1 and 2 (and 3 if you want linux-swap) come up under all the other info.
then type quit
then to upgrade to ext3 type upgrade_fs
then if apps2sd is automatic in your rom of choice reflash it and you are set. i am too nice tonight.

too bad its not that simple. i think he means partitioning since he references not having adb to do the partitioning in the guide i linked him to. (sorry for assuming your gender OP)

i just want to format my ext3 app2sd partition....
it already has fat32 , ext 3 , and linus swap
really only want to format ext3 partition so i can install my new rom
just wondering can you format ext3 partition without havn'ing to erase fat32 and linus swap

paragon partition is aprogram that will enable you to partition your card on your computer and format.

THIS IS WHAT YOU NEED TO DO to format ext. the other guy must've confused u
turn phone off and boot into recovery via home+red key
go to console and type in
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# cd /system/sd
# rm -rf /system/sd/*
# reboot recovery
NOTE:dont type in the # signs. just push enter when done typing each line. and be sure to type everything exact and carefully.but do however type in the * sign.

fdisk with optimus 2x

Hello
I am trying to use fdisk to partition optimus' nand. I want to delete the last 2 partitions /dev/block/mmcblk0p9 and p8 and merge them into p8 but fdisk wont let me do it. It says "value is out of range" and gives me as default 511kb of space each logical partition by default.
If i delete all partitions till p5 and remake the extended partition everything can go ok but these include things i dont wont to touch
For your quick reference the o2x partitions.
/dev/block/mmcblk0p1 = system partition
/dev/block/mmcblk0p2 = cache partition
/dev/block/mmcblk0p3 = misc partition
/dev/block/mmcblk0p4 = unknown partition
/dev/block/mmcblk0p5 = boot partition
/dev/block/mmcblk0p6 = lgdrm partition
/dev/block/mmcblk0p7 = recovery partition
/dev/block/mmcblk0p8 = data partition
/dev/block/mmcblk0p9 = internal SD partition
How can Solve this? Any ideas?

Can someone please upload the contets Of p5 p6 p7?

P5 depends on your ROM
P6 attached
P7 you can get CWM from anywhere really

Thank you a lot rusty its very much aprisiated
Do you know anything about the original question?

No idea I'm afraid.

didn't worked btw
get notification that i got damaged sd so i removed the internal sdcard part from the vold
but still no big ass data partition xD
btw i don't know anything about fdisk i just gave it a shot

look at that... looks like our phone has 16gbs or wrong declare from fdisk?
http://forum.xda-developers.com/showpost.php?p=17001387&postcount=12
edit: apparently it was a wrong declare from my brain

Apparently the SU660 has more internal storage than the P99x, so maybe it's got the same amount really, but the P99x is set up to ignore some of it?

[9001]Mounting external SD Card as ext3

Hey,
I like to mount my external SD Card as ext3 to support large files. The SD Card is formatted with ext3 but now Android shows only an empty folder.
So i tried to remount the SD:
Code:
mount -o rw,remount -t ext3 /dev/block/vold/197:33 /mnt/sdcard/externald_sd
But it doesnt use something... Does anybody has an idea? Some Example or sthing else?

u need a kernel that supports ext3. u can ask one of the guys compiling at the moment if they have time to add an ext3 module for u.

May be a stupid question:
would ext4 work instead? I thought the system partition would use this FS.

filesystem is already ext4

well the system uses ext4 so it should work, but i'm not sure what u're trying to achieve. i use a 16 gb class 10 formatted fat32

He's talking about formatting external sd-card

When I get him right, he has a file that exceeds the 4GB FAT32 limit.
So he looks for an alternative to FAT32, which might be some kind of ext*-FS.

wintel your right!
In the Android-Hilfe Forum someone said the system expect first an vfat partition and then the ext. I think thats wrong cause its not working but somehow it has to go.
Hmm should I write these mount command I postet in the init.rc? Or something else. Would be very nice if you post your ideas!
Thanks

init.rc+ ext3 module/object included in kernel

Hmm okay thats good but how do I use them? So I can read and write to my external sd card with an ext3 or ext2 partition.
Thanks

Come on guys where are the great developers?!

Ok I did a test with busybox inbuilt mount, but I tried only with an image.
Not with a real SD card! This worked for me:
On a linux box:
# dd if=/dev/zero of=/tmp/image bs=1M count=1k
# mkfs.ext4 /tmp/image
Copy file to your phone. Then:
On the phone with terminal:
# mkdir /sdcard/mmnt
# busybox mount -o loop /sdcard/image /sdcard/mmnt
To unmount:
# busybox umount -l /sdcard/mmnt

Anybody tried that?
If I understand u right u puting an image file (ext3/4) on the sd and mount that as a virtual disk. Wouldn't the image file be bound to the same restrictoins as other content on a fat32 file system? Like the 4 gig limit!

YOU WILL LOSE ALL DATA ON YOUR SDCARD IF YOUR FDISK
BACKUP WHATEVER IS ON THERE FIRST!!!
YOU'VE BEEN WARNED
using a photon 4g but....
what i did was get an external sdcard reader writer...
(used ubuntu) and let it mount
fdisk device and DELETE ALL PARTITIONS
write
fdisk again
create a linux primary type 83
type mount and grab the /dev/sdcX value (it was /dev/sdc1 for me)
umount that
then
mkfs.ext3 /dev/sdcX ... ( heres the thing though with cyanogen mod 7 kernel 2.6.32.9 SMP PREEMPT)
had to reboot twice for it to be seen in file manager...
its buggy but it does work for the most part

Reviving an old thread, but I just found that I can format a MicroSD under NTFS and it will work with Paragon's NTFS module. At the very least, my phone will mount the drive. I partitioned and formatted it with ext4 on my Linux machine and it didn't recognize it, but I did have it use the GUID partition table. Hoping to be able to load up some videos to take with me.

The problem is with the shell interpreting the special character ":"
To make it work, first create a symlink to the device node:
Code:
ln -s /dev/block/vold/197\:17 /dev/sd2
Then mount it:
Code:
busybox mount /dev/sd2 /mnt/tmp
Code:
sh-4.1# ls -l /dev/sd2
lrwxrwxrwx root root 2013-11-16 14:45 sd2 -> /dev/block/vold/179:17
sh-4.1# mount|grep sd2
/dev/sd2 /mnt/tmp ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

success mounting ext formatted SD Card on Android
An improvement in technique to mount ext formatted SDcard:
1) be root and open terminal
2) insert the card
3) see the block device and partition names from dmesg
4) mount device to location of choice (create the directory if needed)
Below is an example of an SD card with one ext4 partition on it
Code:
bash-4.1# dmesg | tail | grep mmc
<6>[20230.719541] mmc1: new high speed SDHC card at address 0007
<6>[20230.722803] mmcblk1: mmc1:0007 SD32G 29.3 GiB (ro)
<6>[20230.728352] mmcblk1: p1

Would this work just the same way with i9000?
After this, no more access to the extSD by the Windows PC but only with Ubuntu, right?

Since it's generic Linux kernel and busybox functionality it should work on any 'droid. The SDcard device name might be different than in the above example - you will see the correct device and partition names after you insert SDcard and run `dmesg | tail` on the tablet or phone.
(of course your device must be rooted and have busybox...)
Typically Windows is engineered not to recognise anything that does not come from Microsoft, so you will not be able to mount the Linux partition via Windows.

Safestrap on ME863

(sorry for my bad english and i still cant post link now)
According to http:// forum.xda-developers.com/showpost.php?p=20976390&postcount=294 ,
I think it may work to redirect partition into SD card, so that safestrap will work on non-VZW-phones.
Safestrap uses /preinstall as a new /system partition to install 2nd ROM on it,
We can make a new partition on SD card to replace "/preinstall".
Here is my steps:
backup your SD card and make partitions
boot to safestrap recovery with usb connected to your PC
plug to PC first, then boot to safestrap recovery mode,
now you can use adb shell to control your system.
1.1 make partitions on your SD Card (ref: http:// forum.xda-developers.com/showthread.php?t=534714)
SD card is /dev/block/mmcblk0 so use parted to modify it
Code:
~ # [B]parted /dev/block/mmcblk0[/B]
GNU Parted 1.8.8.1.179-aef3
Using /dev/block/mmcblk0
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) [B]print[/B]
Model: SD SU08G (sd/mmc)
Disk /dev/block/mmcblk0: 7948MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 32.3kB 7946MB 7946MB primary fat32 lba
(parted)
as you can see i have a 8G SD card, fullly used as fat32 partition,
we use rm and mkpartfs to modify our SD card partition, make sure you have backuped your SD card.
for compatibility i choose to make fat32 partition first,
(512mb/1G for new system size is enough, but i want my 2nd system partiton bigger)
Code:
rm 1
mkpartfs primay fat32 0 6G
mkpartfs primay ext2 6G 100%
after done all the things you can see your partition by print,
e.g.
Code:
(parted) [B]print[/B]
Model: SD SU08G (sd/mmc)
Disk /dev/block/mmcblk0: 7948MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 32.3kB 5996MB 5996MB primary fat32 lba
2 5996MB 7946MB 1949MB primary ext2
(parted) [B]quit[/B]
1.2 format fat32 partitions
Code:
busybox mkdosfs /dev/block/mmcblk0p1
1.3 make ext2 -> ext3
sometimes you have to mount /dev/block/mmcblk0p2 first, depends on the tune2fs version
Code:
tune2fs -j /dev/block/mmcblk0p2
or you can do ext3 -> ext4 by typing (i never tried, dont know if safestrap support ext4 ??)
Code:
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p2
e2fsck -fpDC0 /dev/block/mmcblk0p2
Modify safestrap to use our new partition as 2nd system partition
after you install safetrap 1.08, you have some files in your original system,
we have to modify the /preinstall partition (/dev/block/mmcblk1p23) to our new partition (/dev/block/mmcblk0p2 as example here):
2.1 modify /system/bin/logwrapper
find /dev/block/mmcblk1p23, replace to your new partition
Code:
# mount preinstall and move /preinstall/etc/rootfs/* to /
/sbin/busybox mount -t ext3 [B]/dev/block/mmcblk0p2[/B] /preinstall
2.2 modify fixboot.sh in /system/etc/safestrap/2nd-init.zip
find /dev/block/mmcblk1p23, replace to your new partition
Code:
/sbin/busybox ln -s [B]/dev/block/mmcblk0p2[/B] system
2.3 modify etc/recovery.fstab in /system/etc/safestrap/recovery.zip
find /dev/block/mmcblk1p23, replace to your new partition
Code:
/system ext3 [B]/dev/block/mmcblk0p2[/B]
reboot for reloading settings
safestrap need to reload settings, we need reboot.
modify your 2nd ROM to make sure everything works
safestrap loads etc/rootfs from your new partition,
we need to modify /dev/block/mmcblk1p23 to our partition.
you can modify the ROM (.zip) file directly or edit them after installing ROM
just find /dev/block/mmcblk1p23 and replace them to your new partition (e.g. /dev/block/mmcblk0p2 here)
Special thanks to hashcode.
Enjoy safestrap on non-VZW-phones !

[GUIDE] External2Internal Ultimate for Galaxy Tab P1000

I thought about this idea while comparing my Android phone to my iPhone.
Both systems use variants of Unix, but the implementation is very different: there is one partition available to iPhone users, where all apps/music/everything gets installed. If you have a 64GB iPhone, this means you never run out of space for apps.
On the other hand, having a 16GB Android phone and a 64GB Micro SD puts you in a bit of a predicament, rather than a better place compared to the iPhone owner. Some genius has decided that there should be a 1-2GB /data partition where your apps go, and their data goes into the internal SD card; about 100-200 apps down the line (clearly, more than you need, but who are the android designers to judge), you run out of /data space and you end up doing ridiculous things like moving apps to SD, using some form of link2sd/data2sd script etc… Meanwhile you realise that your 64GB microSD is dead space and all you can do is store photos, music, video etc in it - rather than Asphalt data or Navigon maps.
This can change if you have a rooted phone! It took me a while to figure it out, but I first did it on my Galaxy Note N7000 following this guide: http://forum.xda-developers.com/showthread.php?t=1887864 and then decided to create a new guide for my Galaxy Tab 7 (P1000). Credits to badge2033 for the first guide.
After following this guide you will have:
* supersized data partition (12 gigs): no more move to sd needed and then again the stock move to sd feature will work as expected (it will move data to the actual external sd card)
* external sd card mounted as internal sd card: nothing to say here, just does what is expected
* real internal sd (ums partition) shrunk to minimum (half gig) because it needs to stay present: used to mount a swap file (optional)
What you will need:
* Rooted Galaxy Tab P1000 - hopefully running Android 4.3 HumberOS CyanogenMod, but not necessarily (this guide is made with CM10.2 in mind)
* Working knowledge of ADB / Google to get you through bits if you get stuck
Code:
/* Standard disclaimer: Your warranty is now void. Use at your own risk.
Modifying or replacing your device's software may void your device's warranty,
lead to data loss, hair loss, financial loss, privacy loss, security breaches, or
other damage, and therefore must be done entirely at your own risk.
Every time you do not backup and complain a puppy dies.
No one is responsible for your actions but yourself. Good luck. */
Procedure:
1. reboot to recovery, and connect your phone to your pc
2. run a command prompt and type the following (wait a little bit until the adb server starts on the phone, you can verify it by typing "adb devices" if you get a serie of digits then you're good to go.
Code:
adb shellcat /proc/partitions
You should see something like:
Code:
31 0 7680 mtdblock0
31 1 7680 mtdblock1
31 2 443904 mtdblock2
31 3 22528 mtdblock3
31 4 12800 mtdblock4
31 5 11264 mtdblock5

179 16 1024 mmcblk0boot1
179 8 1024 mmcblk0boot0
179 24 31166976 mmcblk1
179 25 31162880 mmcblk1p1
Backup your /data to External SD. REMEMBER YOU HAVE ALREADY COPIED YOUR INTERNAL SD TO THE EXTERNAL ONE!!! I did a dd backup and a nandroid in CWM. You only need the nandroid to restore later.
Code:
dd if=/dev/block/mmcblk0p2 of=/storage/sdcard1/databack.img bs=4096
Code:
/*** WARNING!!! Do your own backups / nandroids /
write important things down on a napkin, if this does not work for you
and you lose data I'm not responsible!!! ***/
You should see something like:
Code:
498688+0 records in
498688+0 records out
2042626048 bytes (1.9GB) copied, 277.149450 seconds, 7.0MB/s
Then use parted, the partition editor:
Code:
parted /dev/block/mmcblk0
you'll get into the parted interactive shell, this is where serious work done
Code:
unit b
print
You should see something like:
Code:
Model: MMC SEM16G (sd/mmc)
Disk /dev/block/mmcblk0: 15925772288B
Sector size (logical/physical): 512B/512B

3 15820914688B 15925772287B 104857600B primary ext4
Code:
did i remind you to backup your system,this is your last stop before the no back pointso you just might wanna "move" all your internal sd stuff to the external sd,and backup your system to the external sd also (you just need to restore the data partition afterwards the rest of the system is safe but who knows :p)ps: you can do your backup on cwm without leaving adb shell on the pc just like you will do the format later thanks to cwm
remove the partitions
Code:
rm 1
rm 2
make the new changed size partitions
Code:
mkpart primary 32768 536903167
mkpart primary 536903168 15820914687
print
you should see this output
Code:

3 15820914688B 15925772287B 104857600B primary ext4
Format the data partition as ext2 (so that CWM can see it)
Code:
mkfs
Then choose 2, ext2
now in cwm go to mounts and storage and select "format /storage/sdcard0" and "format /data"
now restore your data partition in CWM.
and you will be able to boot you system normally. and you go to your storage information you will find that your app storage is now 13gigs and the usb storage is just 500 megs yay
For Android 4.3 modifying vold.fstab file (but for other versions do so with ciphray's guide on how to do so)
you can use the modified file from ciphray thread here which i didn't beacuse his file was smaller
What DOES work is the free External 2 Internal app in Google Play: https://play.google.com/store/apps/details?id=eu.codlab.int2ext&hl=el
Settings are (for CM 10.2 ROM):
Original Internal mounting point: /storage/sdcard0
Original External mounting point: /storage/sdcard1
Ext.sdcard device access: /dev/block/vold/179:25
[Have not done this - badge2033 suggests it]
as a final step you can use the now pretty useless internal space (500megs remember) as a swap sapce
download swapper2 from the play store here https://play.google.com/store/apps/d...v.n3o.swapper2
run it and go to settings
set swap place as /sdcard/external_sd/swapfile.swp
set swap size to the max
set the swappiness to 20 ( you can rise the value a little but don't put a high value or the system will do much swapping all the time -value of 100 means any memory not used actively will be swapped- )
wait until the process finishes then reboot your phone
you can verify that swap is working by typing "free" in the shell if the line beginning with swap is not all zeros then you're swap is working.
Phew! That was a long guide. Questions / comments below.

Good idea!
im waiting for better CM 10.2 and will try (my p1000 is on alroger's cm 10.1 now)

Just to be sure to have understood everything.
You have convert the internal storage in data partition but It can't be use anymore as a storage?
Thanks

Yes. The original partitioning of internal storage is about 2gb data / 12gb storage, now it's just 500mb storage. Then with the sd card swap this 500mb becomes obsolete as a 32 or 64 gb microSD takes the place of storage.

help me.
I really like the way you propose, I like to do this but,
after going to recovery and plug in,i open a cmd(admin) and type adb devices and this massage appear:

Click to expand...

Try entering separate commands in the command line
adb shell
cat /proc/partitions
You are welcome.

Thanks for this post. In my case, this method somehow unlocked hidden 16GB storage. Without microSD inserted, it has 14GB of internal storage (where you can have your apps)... and 15GB of SD internal storage. (can be used as usb drive and storage for movies and music and books)

Moving EVERYTHING to external SD card
Hello,
Sorry for necroposting, but I'm looking for a way to revive a Samsung Galaxy Tab GT-P1000 that had a damaged internal storage chip physically removed.
I managed to intall CyanogenMod 13 on the external SD card partitionned as follow :
Code:
cat /fstab.p1
# Android fstab file.
# <src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
recovery /recovery mtd defaults recoveryonly
boot /boot mtd defaults recoveryonly
radio /radio mtd defaults recoveryonly

/dev/lvpool/userdata /data f2fs rw,noatime,discard,nosuid,nodev,nodiratime,inline_xattr wait,encryptable=footer,length=-16384

# zRAM
/dev/block/zram0 none swap defaults zramsize=134217728
However, most apps crash when started, as they expect a writable internal storage, and there is none.

What I'm looking for is a way to use the external SD card as /system, /data, AND internal storage. Can anyone help me achieve this ?
