How do I completly clear out my ext2 partition through Terminal emulator

I had to wipe my phone and have ext2 partition on my card but when I try the copy.sh app command it works but always hangs on the flashing g1 after I reboot the phone. So this leads me to believe its because the apps are still there on the ext2 partition and need to be removed before I could do it again.

well you can try flashing LucidREM mod that has the files for mounting it located here and instead of using the copy.sh app first try this.
$su
# cd /system/sd
# ls -la
check if the app folder is there if it is than
# cd app
#ls
check if the files are there.. and if they exist than try this
# rm -rf /data/app
# ln -S /system/sd/app /data/app
# reboot
hope that helps and it u still want to wipe the ext2 parttition than jut
# rm -rf /system/sd/*
or
# rm -a /system/sd/*

I kinda had the same question but was wondering if there was an easier way of wiping the ext2 partition? I'm kinda new at all this and am now starting to get the hang of flashing different roms onto my phone but I realized that doing an Alt+W before flashing new roms does not wipe the ext2 partition. (At least I'm pretty sure it doesn't.)
I'm not too savvy on using terminal yet..I've heard of using adb but I don't even know where to begin with that..so I was wondering if going into Paragon Partition Manager and just formatting the ext2 partition will work? Any info will be greatly appreciated.

Ok i finally have it working. I keep getting a social network force close.

there is an app on the market called lucid REM that runs his script via terminal emulator. after getting it and running it you can go to terminal and type
su
lucid -c (this wipes ext2/3 partition)
hopefully this helps you. if you are on a rom that uses auto a2sd then you will most likely getting force closes all over until you flash your new rom.

I posted a thread with steps to do it http://forum.xda-developers.com/showthread.php?t=533731
Code:
Open console and enter the following commands. Press "Enter" after each line. This wipes the ext partition.
mount -o rw /dev/block/mmcblk0p2 /system/sd
rm -r /system/sd/
[code]

Glad this wasnt deleted right away, maybe it can just be moved?
It helped because I also was wondering the best way of doing this, and now I know.
Thanks .

Odd, double post for no reason. Sorry delete this post?

is there a way to format ext3 partition (app2sd) from g1 phone or from recovery mode

-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.

errr wrong post

Clear a partition

I'm looking to delete all the data and subfolders in my partitions ext3 and linux-swap, start fresh.. i dont feel like going through that long procedure of removing the actual partitions and then re-adding and allocating the blocks.
I don't use adb, i just use the console from cyanogen's recovery page. i just starting learning all of this fun linux stuff when i got my dream a few months back =P
So what's the commands to mount, then clear the info on the partitions including all sub folders?
TIA!

Boot into recovery home+power
Go to console ALT+X
type:
(press enter)
#
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# rm -rf /system/sd/*
# reboot recovery

Much thanks! worked great.

Noob Question - Wipe phone

so i want to wipe my g1 to delete all of its apps.
however I would still like to keep my contacts and sms's/emails.
is this possible? if so, how do i do it?
thanks, God Like

your email's and contacts should be synced to google's servers if you keep sync on. if not just manually sync it a few times to get it to register on the servers. you can back up your messages.
or if you have fastboot, you can make a nandroid back up. pull userdata.img and use fastboot flash data userdata.img or something like that to put it back on your phone.

totally forgot that they were on google :/
but remember i am a noob, how do i wipe lol?
also my apps are on sd so will it delete them off the partition?
also will it delete everything else on my sd?
lastly, it wont delete my rom or root will it?
thanks

well to wipe your phone, boot the phone into recovery (home and power) and there is an option in recovery to wipe your phone. that will clear cache and data.
to wipe your ext2/3/4 boot into recovery, then choose the option recovery console, once in the recovery console hit enter, there will be a prompt to hit enter, so that is how you will know you are in the recovery console. after you hit enter type
Code:
mount /system
rm -r /system/sd/*
that will delete everything off of your second partition.
if you either wipe your phone or format your sdcard, it is recommended that you reflash your rom. but you will not lose root by just wiping your phone or formatting your sdcard

/system/sd is what the phone recognizes the ext2 partition to be. try
Code:
rm /system/sd/*
or
Code:
rm -r /system/sd
or
Code:
rm /system/sd
if that doesn't work then try
Code:
mount -o rw /dev/block/mmcblk0p2 /system/sd
cd /system/sd
rm -r *
that and see if it will work.
make sure you are doing this from the recovery console.

If you are using cm recovery 1.4 you can go into the recovery console and type ums_enable to acess the sdcard with nothing running on it, I just did it to wipe my sd and start over fresh and when you are done type ums_disable to unmount the sd and type reboot to restart the phone

hey, thanks this apparently worked. It replied a # which tells me it worked and when i tried to repeat the command it said (code) could not be found...but after i rebooted, all my apps are still there...and they work. I reflashed and everything still is there
any ideas?

Can I format my Ext3 partition without removing my card?

Hi, just wondering if it is possible for me to format my ext partition on my SD without actually connecting it to my PC, I have looked around and have no clue of what command I can enter into the recovery terminal to do this, any help is appreciated lads, cheers.

Next Time ask question to Q&A section.
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

someones gonna be suspended lol.......enter parted from 1.4 cyanongen recovery
parted dev/block/mmcblk0 (hit eneter)
print (hit enter)
rm 2 (hit enter)
hopefully rm2 is ur ext3
then type
mkpartfs primary ext2 xxxx xxxx
xxxx= your last numbers from rm 1 example 3453 3901
the size of your ext3 befor you rm 2.
after initializeing this type
quit(enter)
now type
upgrade_fs (hit enter)

Only if you know magic!
Post in the Q&A, its there for a reason (the Q stands for Questions, like the one you have, and A stands for answers, like the ones you'll get for posting in the right section)

Someone may have a better way, but this is pretty much straight forward info (From Recovery Console):
STEP 1: Hit "Enter"
STEP 2: type '# parted /dev/block/mmcblk0'
In parted:
STEP 3: type 'rm 2'
STEP 4: type 'mkpartfs primary ext2 xxxxx xxxxx' (your partion size range "xxxxx xxxxx")
In terminal:
STEP 5: type 'upgrade_fs'
STEP 6: type 'reboot recovery'
That'll create a completely new ext3 partition.

bigslanki/jugg2000, you don't need to delete the old partition to go that method, just
Code:
parted dev/block/mmcblk0
mkfs 2 ext2
y
Actually I know that doesn't work because of a bug in parted, you have to do:
Code:
parted dev/block/mmcblk0
mkfs
y
2
ext2
but it's the same.

Sorry about asking here lads, completely forgot we have a Q&A section because my bookmark takes me straight here to the dev section, cheers for the replies though, much appreciated.

Here's now I normally wipe my EXT3
Code:
mount /system/sd
rm -rf /system/sd/*
Quick and easy.

this is quick, easy, painless, and will make sure nothing is left on the partition.
in recovery console
Code:
mke2fs -j /dev/block/mmcblk0p2

I hate to ask, but rather than create a new thread.... why would one format their Ext3 partition?
If you do format it, I suppose you could create Ext 4 at that point.... Any advantages of Ext3 vs. Ext4. I looked at Wiki but it confused the bejesus out of me.

to remove all of the files off of it, like if you are going from a hero rom to an AOSP rom, also from what i have heard there are no huge differences in ext4 that would be of significant benefit for your phone or sdcard. i have had an ext3 and ext4 partition (went back to ext3 after formatting because i didn't feel like entering in the extra commands, and i have not noticed any difference in ext3 or ext4), but if you do want to try ext4 and already have ext3 do this in the recovery console
Code:
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p2
e2fsck -fpDC0 /dev/block/mmcblk0p2
then you will have ext4, voila.
