My first script!

So I got sick of typing
$su
#mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
#chmod 777 /system
So I wrote a script and I just click on it in gscript.
Does this officially make me a white belt, lowest rank possible dev? Aahaha
Pm me and I can send you the script if you want haha.

Congrats on the script! It's get's easier now that you have the concept - then it gets hard again lol.
While we're on the subject of scripting - any reason you choose that system rw mount script? There's 3 ways I've seen it done and they are all completely different... maybe the have different functions?
Again, good job and I like your idea. I saves a lot of typing especially with those commands since we type them a lot.

I think just by writing a successful script.. you are already above MANY xda users.
Kudos.

His script mounts the system as rw.
Sent from my T-Mobile G2 using XDA App

Nice script
What I do is a little different. I have it saved as my initial command for terminal, so it starts whenever I use terminal.
The code I use is this:
export PATH=/data/local/bin:$PATH
su
mount -o rw,remount /system
I am obvlious though as to why you put yaffs2 and mtdblock3 and all that, I never thought it was necessary since it works just fine without it. I'm not too keen on linux syntax though so its probably obvious but I'm curious anyway.

That's what my question was too lol. It's a great script especially for his first but now he should make it less bulky. If it's being ran in terminal as a script then all he would really need is this:
Code:
#!/system/bin/sh
mount -o remount,rw /system
I don't believe you need to use su before running it but I always do just in case.
Of course you'll want to make a /system ro script (unmount) too so you're not always in mounted in rw access.

Haha, thanks!
I found that leaving out the yaffs2 etc didn't work. I read somewhere that you need this line with certain kernels. I wish I could give you a more learned answer though.
I'm thinking it's a good idea to put the system back in ro too, actually. Now I'll have made two scripts haha
Sent from my HTC Vision using XDA App

Not positive on all of this, so someone can correct me if I'm wrong, but
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
is used to mount system by accessing the NAND (hence the yaffs2 filesystem and mtdblock device). Many of the older Android guides use this command (since the older phones all used raw flash).
The Vision (and many of the newer phones) use an eMMC though, which has an FTL to present the NAND as a block device to the OS (just like a hard drive). This is why in many of the guides written nowadays, you'll see something more like this:
Code:
mount -o rw,remount -t ext3 /dev/block/mmcblk0p25 /system
This accesses the eMMC as a native block device (hence the ext3 filesystem). This is probably the "more correct" way of mounting the partition as it utilizes the actual FTL controller on the NAND as opposed to the more inefficient linux virtual block driver (what mtdblock does), so it's a little cleaner from a software development standpoint. Both commands accomplish the same thing though, so you could really use either.
The shortened form of the remount is what others have been listing:
Code:
mount -o rw,remount /system
Basically, since the system partition had already been mounted by the OS on boot, it should already know the proper way to remount it (i.e., you don't have to retell it the device or filesystem used). I don't believe this command will work on every ROM out of the box though (requiring either Busybox to have been installed or ro.secure=0 to be set in your default properties, maybe both).

Excellent and informative post! So is the reason why the
Mount -o rw,remount /system
Command doesn't't work for me is because busybox isn't installed? I'll test this out right now...
Also, I was thinking chmod 777 might be redundant because the system is already rw. Is this true? My understanding is the chmod 777 simply sets whatever path after it as modifyable. Is there a difference between rw and being able to modify files in linux?

Well if you want to know if you have busybox just do this:
Code:
su
cd /system/bin
busybox
That should start busybox. It will say 'not found' if you don't have it - so if you need it the easy way is to use titanium backup to install it.
Btw, ianmcquinn that was very informative and well written. Thanks for explaining it so well.

Definitely have busybox. Definitely still just gives me the usage information...weird.
How do I set secure=0?
Sent from my HTC Vision using XDA App

ro.secure=0 is standard on most roms, so I asume you are just using a rooted stock build? You will need to unpack your kernel, change the ro.secure from a 0 to a 1, and repack the kernel. If you don't know how to do that, use this.

Virtuous 0.9.0
Sent from my HTC Vision using XDA App

I don't use Virtuous, but I would be shocked if it didn't already have ro.secure=0 set already. You can check by typing this in terminal:
Code:
getprop ro.secure
It should return a 0. This property is set in the ramdisk within your boot.img. To set it yourself, you would have to unpack the image, modify the setting in the default.prop file, repack the image, and then flash it back to your phone. As was said earlier though, pretty much all of the custom roms set this for you already.
Not sure what is going on in your case then. Maybe try running the mount command explicitly through busybox to see if that is the problem.
Code:
busybox mount -o rw,remount /system
If this works, sounds like you may want to reinstall busybox since the symlinks were not properly set up. Another thing maybe worth trying is to swap the order of remount and rw in the options. I've seen reports of this making a difference for some people, but have no clue why it should (maybe different versions of the mount command/busybox). Kind of a long shot. So try either of these commands:
Code:
mount -o remount,rw /system
busybox mount -o remount,rw /system
EDIT: In case you were curious, here's a link I had bookmarked about how to edit the boot.img. I'm sure there are others out there as well.

[Q] Not able to change boot animation

Im running Virtuous 1.0.1 and when i try to change my boot animation through root explorer i cant because it says im not allowed to change system files, what am i doing wrong? i see other people on youtube just change there without a problem but i cant seem to do the same.

Or u can simply use an app on the app store called. Boot Animation Changer Lite. Once u download it you will get a folder in your sd card that says like bootamios or something. Click on stock and delete the zip file that's in there. Drag the animation u want in there the .zip file and exit. Go back to app. Click animation in bottem righht. Scroll all the way down till u see stock and done.

Just use terminal, your app might be messing up or having compatibility issues for some reason.
Code:
su
mount -o remount,rw /system
cp /location/to/bootanimation.zip /system/media
That should do it.
Example:
su
mount -o remount,rw /system
cp sdcard/zips/animate/bootanimation.zip /system/media

i think it might of had something to do with the sense rom i was running, because once i flashed back to cm7 it was a piece of cake

Is there an animation sound that goes with lets say the honeycomb boot animation?

I did once. and I've found that if I go into the bootanim folder and replace the bootanimation.zip in the stock folder, then go to boot anamation changer and tell it to run stock then it will change it to the new file however that just seems like a dumb way to go about doing it.

Any fix for this? (Picture attached)

I got the same error messages after the remount but the "adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system" seemed liked it work. it didnt say anything though

It won't give you a message saying it was successful... just try the other commands to see if you have backuprom.zip on partition 3. If its there... we can fix the issues... if not.. we have to make stuff up to fix it
You can do the same thing for partition 2 (where the device specific stuff is stored unzipped) by creating directory called tmp2 and mounting /dev/block/mmcblk0p2 to it... in that one 3 specific files you're looking for are:
DeviceID
MACAddress
SerialNumber
Those are plain text type files (but not DOS or windows formatted.. so you can view them, but don't edit them in notepad)

adb shell mkdir /system/tmp
adb shell mount /dev/block/mmcblk0p3 /system/tmp
adb shell ls -l /system/tmp

adb shell mkdir /system/tmp2
adb shell mount /dev/block/mmcblk0p2 /system/tmp2
adb shell ls -l /system/tmp2
OR
adb shell
mkdir /system/tmp

etc.
Since you have the rombackup.zip on mmcblk0p3 try this...
extract attached file... then run the resettofactory.cmd file... it will copy the BootCnt file to /rom and make it think its on 8th failed boot.

[Q] [Help] CM9 ROM issue for Chinese language

Hi all-
I tried Reloaded CM9 / Energy™ CM9 and found a strange issue for Chinese language.
After ROM finished the starting, Chinese character will be displayed as "?" for file or folder name in sdcard, I tried almost all file explorers like as RE manager / ES file-explorer or some others and got the same result.
Why I said the issue is strange?
If I mount the sdcard to my laptop and then umount it, or hot reboot my Kindle Fire, or use sdcard remount tool to remount sdcard, the issue will be fixed, Chinese character can be displayed correctly.
I like CM9 very much but the strange issue blocked my CM9 experience.
Someone can help for this issue?
By the way, I also tried below commands to remount sdcard and the issue can't be fixed.
/system/xbin/busybox umount -l /mnt/sdcard
/system/xbin/busybox mount -t vfat -O iocharset=utf8 /dev/block/mmcblk0p12 /mnt/sdcard

it's so strange.
