You talking about tablet or PC?

commands need to be ran in PC side, i suggest you first read all unbrick threads and setup what is needed for example ubuntu linux which is always good to have and now that you have take the plunge to mess with your device with the unbrick methods you will need it so first feed yourself with the basics, THAT MEANS read and watch the videos.

IF WE START GIVING A USER MANY INFORMATION THAT HE/SHE HAVE NO IDEA WE WILL JUST CONFUSE HIM/HER.​

In my FAQ you can find links to many how-to's, tutorials and video-tutorials and in this page http://xdaforums.com/showthread.php?t=1570022 you can watch the videos to install and setup adb on Ubuntu Linux.

If you have questions referring to a specific thread post in the respective thread. Thanks!

I'm not a newbie. I asked previous question only because demetris_I asked me about my OS.

@old_fart of course I have working adb connection between my Arch Linux running PC and NT.
@lavero.burgos I've already tried all your methods. As well as methods by AdamOutler, meghd00t and soshite.

I see all of them and are you able to boot to internal? and have the same read-only problem? that's odd. Well would you mind reformat your sdcard and see if it gets a bit better lol it's all i can think for now 'cause if you really have try it all and we're talking all the partitions overridden and recreated from scratch and you keep having the same problem it's very weird.

i am sorry. i did not mean to offend. when i saw 'fdisk', which ( as you know ) is the disk partitioning utility/command . . . and i thought you asked the senior guy if you should partition the pc -or- partition the tablet... well...

I reformat my sdcard several times. I've tried eveything. Even fastboot via cyanoboot by fattire.
It seems that nothing can't write anything. Look at the parted log on previous page.

Your adb wasn't echoing back so i assumed you run linux or you have a bad adb shell.
Please share with us how you reformat your internal sdcard.

ok let me compare with mine and ill post the output.

Ok the #Mount in cwm is the same no problems there but the #mount in Android change to ro in 2 parts:

rootfs on / type rootfs (ro,relatime)
... should be rootfs on / type rootfs (rw,relatime)

/dev/block/platform/mmci-omap-hs.1/by-name/system on /system type ext4 (ro,relatime,errors=panic,barrier=1,data=ordered)
... should be /dev/block/platform/mmci-omap-hs.1/by-name/system on /system type ext4 (rw,relatime,errors=panic,barrier=1,data=ordered)

thing is it change to ro when it boots.

Can you try:

$ su
# mount -o remount,rw /dev/block/mmcblk0p8 /system

mount -o remount,rw /
mount -o remount,rw /system

It didn't change anything.

I was explicit:

# mount -o remount,rw /dev/block/mmcblk0p8 /system

try that, for what i're read a reflash should fix it. But i think you already have tried that. We could also try a script under /etc/init.d

I read your previous post before you edit it.
Anyway, "mount -o remount,rw /dev/block/mmcblk0p8 /system" didn't help.

adb remount, works?

Remount remounts the /system partition as writable (or readonly if it is already writeable)

"adb remount" says that "remount succeeded". But actually memory remains read-only: after reboot all changes revert back.

I have similar problem, i cant fix it to. Try using this:
mount via adb internal partition
11 13.6GB 15.9GB 2315MB ext4 userdata

mkdir mmc0
mount /dev/block/mmcblk0p11 /mmc0

add try to copy file large >1GB(like hd-rip video) -file must be lagre that operating memory(1GB),
adb push <file_>_1GB> /mmc0
wait 3-4 minutes
if you nook restart you will catch memory overflow. I think that this hardware failure...
... but if not, it good news.


try
adb shell
umount /mmc0
reboot

then via adb
mount /dev/block/mmcblk0p11 /mmc0
ls -l /mmc0
if you see your file, MMC memory ok, you can try restore method

(могу попробывать поковырять, без гарантий, от 200 грн, киев)
