Help! Syntax please

mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
I have typed that in 5 times and it says it's a syntax error. I'm guessing it's a space issue or something. My phone is down.
What is the exact syntax?
Thanks

Are you sure your at the root prompt? Looks like this # and not this $

That syntax is correct. Are you invoking busybox's mount?

I finally got it, thanks.
The way it shows in the root guide is:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
The way I had to type it.
mount -o rw, remount -t yaffs2/dev/block/mtdblock3/system
It turned out to be a spaces issue.
I got that part done and then is said "Can't cd sdcard"
My sd card is formatted fat 32 and loaded the rc29 fine but won't cd to sd card. Does it need partitions or something?
Honestly, this is one of the most frustrating things I have ever done in trying to root this phone. Now I can't even use mount -o rw, remount -t yaffs2/dev/block/mtdblock3/system.
Please help me out I am still getting usage errors. It must be something to do with spaces in the syntax of mount -o rw, remount -t yaffs2/dev/block/mtdblock3/system

The syntax of those lines is all messed up. You need spaces between "yaffs2" and "/dev/block/mtdblock3" and "/system". If your phone is already rooted, just hook it up to adb and type adb remount.

Thanks jashsu, that did it. For a total noob like me, I just didn't understand.

Newb terminal command questions

What's the difference between these two (at least why they use the mount command, remount command, or shell command?)
su
mount -o remount,rw /dev/mtdblock3 /system
rm [whatever i want]
mount -o remount,ro /dev/mtdblock3 /system
and
adb remount
adb shell rm [whatever i want]

The first is a terminal command from the phone. (Only requires the phone)
The second is through adb to the phone. (Involves a properly configured adb, computer, usb cable, and phone)

Wow, so people manage to type out all that craziness on the phone huh.
Thanks!

Anytime. Doubt they do that all the time, it would be easier to just make a script if you have to do that more than once. I just use root explorer, it has a button that mounts /system/ -rw.

I'm not sure about other terminals, but you can create aliases in Better Terminal Emulator
alias rw='mount -o remount,rw /dev/mtdblock3 /system'
alias ro='mount -o remount,ro /dev/mtdblock3 /system'
so now all you have to do is type rw or ro and it executes the full command. Or you can create scripts:
su
mount -o remount,rw /dev/mtdblock3 /system
cd /system/bin
echo "#! /system/bin/sh" | tee ro rw
echo "mount -o remount,rw /dev/mtdblock3 /system" >> rw
echo "mount -o remount,ro /dev/mtdblock3 /system" >> ro
chmod 755 rw ro
Same thing, except it executes the scripts instead of an alias.

[Q] adb remount vs. mount -o rw,remount -t yaffs2 ...

So in several "how to remove apk" threads, I've seen 2 different ways to go about removing apks.
1)
Code:
adb remount
adb shell rm /system/app/blah.apk
2)
Code:
adb shell
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# rm /system/app/blah.apk
My questions is, is there a difference between adb remount and mount -o rw,remount -t yaffs2blahblah?

The long command can be run on a terminal emulator on the phone so you can do other things without a computer.

[HELP] broken lcd + after working with adb doesnt boot

Hey xda-community,
might be a long text to read but i want to make it as detailed as possible :/.
I have an i9070 with broken lsd (+touch not working) and pattern lock.
i booted into recoverymode (TWRP) and removed the pattern lock via adb shell ("rm /data/system/gesture.key").
i wanted to use [email protected] so i tried to activate USB Debugging via adb shell.
in the internet i found a method and tried it right away
i had to pull /system/build.prop
add the line "persist.service.adb.enable=1" in the file
and after that i had to push it back, but i couln't.
So i searched to mount /system r/w ..... (prob for the false device ,_, )
i tried the 1st command and forgot the 4 in ext4, so i typed it like this in the adb shell:
# mount -o rw,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o rw,remount -t ext4 /dev/block/mmcblk0p8 /system
after that i was able to push the build.prob back, and used
# mount -o ro,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o ro,remount -t ext4 /dev/block/mmcblk0p8 /system
afterwards.
Rebooted it and it stuck while booting prob.
So i tried the push back the original build.prop. (thought it might be the cause)
Still not booting..
I ended trying all commands without any order:
# mount -o ro,remount -t ext /dev/block/mmcblk0p3 /system
# mount -o rw,remount -t ext /dev/block/mmcblk0p3 /system
# mount -o ro,remount -t ext4 /dev/block/mmcblk0p3 /system
# mount -o rw,remount -t ext4 /dev/block/mmcblk0p3 /system
# mount -o ro,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o rw,remount -t ext /dev/block/mmcblk0p8 /system
# mount -o ro,remount -t ext4 /dev/block/mmcblk0p8 /system
# mount -o rw,remount -t ext4 /dev/block/mmcblk0p8 /system
chmod 755 system
chmod 777 system
i used also mount..../mmcblk0p3 instead of mmcblk0p8 because after using "mount" it showed behind the /system mmcblk0p3 ...
i messed too much around as a newbie :crying:
I am still able to use adb in recovery mode but cant acces the internal storage.
Would be nice if someone could help me
Ty if you read the whole text .. ^^

this method would solve the changed partition problem xt 1078 by the xt1068 partition.

You read that right ?, while installing THEME, is appended to the menu "mount" The "persist" partition friend. please follow the instruction
Work Only in the version ** TWRP 3.0.0-1 **, and Version 1 from the theme or 2, I am no sure in this moment. [emoji16]
