apps2sd reboot loop

hi everyone,
***i searched and searched but i couldnt find the answer***
i had apps2sd on a previous rom and i recently switched to the mytouch rom.
after i wiped and applied update, i get stuck at the boot loop. i know that this is caused by the apps2sd and i remember seeing a set of commands that erase it from the sd card but it was deep in a thread and i dont remember which thread it was.
can someone please help me ( and others) out by posting the commands that will get it past the boot loop?
i tried this in the recovery console but it didnt work:
mount data
ln -s /system/sd/app /data/app
Thanks guys!

also tried this but it didnt work:
mount data
rm /data/app
mkdir /data/app
im still stuck on boot loop

Code:
mount -o rw /dev/block/mmcblk0p2 /system/sd
cd /system/sd
rm -r *

mount -o rw /dev/block/mmcblk0p2 /system/sd
cd /system/sd
rm -r *
does that delete everything on the sd card?
this gives me an invalid argument error:
"mount -o rw /dev/block/mmcblk0p2 /system/sd"
i can get to
/system/sd #
when i type in cd /system/sd
?????what do i do???

said what the hell and tried the rm command and i got permision denied on everyfile it tried to erase

easiest way would be to reformat your ext partition.
then wipe and reflash
other roms can leave junk in the ext partition that causes bootloops quite often. this is a very common problem and i always find a reformat, which takes like 30 seconds with gparted live cd, fixes it

is there a way to do it through the phone?
my micro sd adapter broke and im waiting for amazon to send my a new one

Ubuntu Help !

Hey Guys wondering is someone can assist
i been using different ROMS for about 3 months now
i have several SD card that have been partitioned to FAT32 and Ext3
however i recently purcahsed an 8GB card but what i want to do it change cards but i want to copy my Ext3 partition so its just a matter of drag and drop to the new card
however via ubuntu its not letting me access Ext3 partition, it clearly shows that its there but wont let me mount it .... can mount up FAT32 with no issues
if someone could assist it would be greatly appreciated
Running latest ubuntu 9.04 from Live CD

if you have the android sdk set up I believe you can pull it, create the partition and then push the files to the partition that way. Not sure if ubuntu can mount an ext partition. Google!

not sure if it is ROM specific but I can mount ext from linux using cyanogens rom.
plug phone in and click mount usb.
from linux open console
Code:
dmesg # to find out which device (mine is /dev/sda)
sudo fdisk -l /dev/sda # or whatever dmesg said
sudo mkdir /mnt/tmp
sudo mount /dev/sda2 /mnt/tmp
ls /mnt/tmp #should show contents of ext3 if it worked
copy files
Code:
sudo umount /mnt/tmp
on phone click unmount usb or whatever.

Strange, Ubuntu always mounts my ext3 no problems. You could try pulling the file to you fat32 on the old card, copy them to fat on the new card and push to the ext3
On the old card
cp /system/sd/app/* /sdcard/app
Cp /system/sd/app-private/* /sdcard/app-private
Then copy those 2 folder to the fat32 of the new card, then:
Cp /sdcard/app/* /system/sd/app
Cp /sdcard/app-private/* /system/sd/app-private
You will have to remount /system and mkdir's first, though.

Ill check thos out my friend
thanks , i will report bk

It's a little odd what it does with the ext partition. I noticed it did not show up except in /media. The fat partition gets a shortcut on the desktop. If you have gparted on your machine, open it up and it should tell you where it mounted it to (if it got mounted).
Good luck.

dmesg
sudo fdisk -l /dev/sdf
sudo mkdir /mnt/tmp
sudo mount /dev/sdf2 /mnt/tmp ..... SO FAR THIS WORKS
when i enter this command ..... ls /mnt/tmp ..... i get error message "ls: cannot open directory /mnt/tmp: Permission denied"
any other idea's

through terminal ? or linux command ? or through recovery mode ?
also can you give instructions to remount system , only if you can
cheers appreciated
also any idea's why your fat 32 AND ext system auto shows so that files can be dragged and dropped ?

Was posting from my G1 late at night so I was feeling lazy
to remount /system as rw
mount -o rw,remount /dev/block/mtdblock3 /system
input those commands in to the recovery console, it's not a good idea to push apk's while your phone is on (I mean, it is in android).
No idea. I'm on Ubuntu 9.04, it auto mounts them and opens them, they also appear in the sidebar in nautilus.

Cp /sdcard/app/* /system/sd/app

OK that never worked , anymore idea's ?

Since this is Ubuntu Help, i figured i'd post this here, if it is the wrong forum, let me know.
I am trying, and have been for a week now, to use
Code:
adb shell
however, it keeps giving me the message
Code:
device not found
i know it's there because i am able to mount the sd to my pc and browse the files, but adb doesn't find it. device not found....
any help?

You need to edit a couple of files first. Google is your friend.

backup ext3 partition

Hey guys,
is there a way to backup the ext3 partition? when flashing Drizzys ROM you must have a clean ext3 to do initial boot. without clean ext3 you get a bootloop. Ive flashed his ROMS several times and i want to flash a new cyans 4.0.1 but im afraid that ill lose my apps.
any ideas on how to keep your info AANNNDDDD flash drizzys ROM??

If you have adb up and running you can adb pull /system/sd/app (some directory on your computer) to make a back up the adb push (same dir from above) /system/sd/app if you don't have adb then i do not know

If you ant to go from Drizzy to Cyan you should be fine. Just wipe and flash Cyan.
For fututre refrence, to back up your ext, go in to the recovery console
Code:
mkdir /sdcard/app/
mkdir /sdcard/app-private/
cp /system/sd/app/* /sdcard/app
cp /system/sd/app-private/* /sdcard/app-private
All that does is make the "app" and "app-private" folders on the fat32 partition of your sdcard and copies the apps to them from the ext3 partition (the mount point of ext3 is /system/sd).
To push them back after flashing a new ROM (again from recovery, don't do this from the terminal when your phone is on):
Code:
mount -o rw /dev/block/mmcblk0p2 /system/sd
cp /sdcard/app/* /system/sd/app/
cp /sdcard/app-private/* /system/sd/app-private
This time was also have to mount the ext3 as re-writeable so we can copy to it.
Hope that helps.

or just do cp /system/sd/* /sdcard
gets you all the folders in /system/sd

This makes it really easy http://forum.xda-developers.com/showthread.php?t=549876

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

be careful what you wish for...
you need to remount the partitions. you can do this through adb shell or terminal emulator on your device.
Adb commands
Code:
adb shell
su
mount -o rw,remount -t ext4 /system
mount -o rw,remount -t ext4 /vendor

You need to unlock the other parts of your bootloader then. It will factory reset the device, but you need unlock flashing and unlock flashing critical. This let's you remount critical partitions. Vendor is a critical partition.
