Micro SD Write-Protection error !!

This is an unusual problem. I am using a 2GB Sandisk MicroSD card on my G3 running a slightly modified version of DDJP2. The problem i am facing is that i can neither delete the contents of my MicroSD Card nor format it. Here are the steps i took:
1) Tried deleting folders individually as well as batch-wise
2) Unmounted & Formatted SD Card from Phone
3) Connected to a PC running XP SP3 (Both in Kies & Mass Storage mode) and tried to delete / format
4) Tried both quick format as well as the total format
5) Flashed different firmwares, wiped cache/data, hard reset and then formatted
In all the above cases, when i re-checked the SD Card, i could all the original files available on the card. Surprisingly, all the folders e.g. the music/songs folder was working fine.
Deleting the folder(s) shows that the content is write-protected; therefore it is probably not letting me delete or format the contents. While searching for possible solutions i came across some (unique?) methods -
1) Flipping the "write' switch -- Not possible since i do not use an adapter and the MicroSD hasnt got one built-in
2) Taping a notch - Wasnt sure what that meant exactly
3) Try formatting the MicroSD in a Camera - Eh ?
Anyone could possibly enlighten me on how to remove the write-protection on my MicroSD w/o using any kind of external device and possibly by software manipulation only ?

I am too having this exact problem. it's a 8gb micro sdhc.
have you solved it or it was a malfunction on the card?

maybe you should try formating it in cwm?

cwm--clockworkmod recovery.
if you have extended power menu you can enter in it by that way....if not...power off phone..then...hold volume + and - together and press home key and then power on key...hold them together until samsung logo appears then let them go...phone will boot in cwm recovery mode...

the problem is that I don't have a samsung phone. only posted here because os a google search about my problem.
although I have an htc magic 32a but I don't know if I can do that here...

No, i couldnt solve the problem and replaced the card. Although my folders on the "defective" card work fine and i can even transfer them via bluetooth. I must admit i didnt try CWM wipe at that time although i did try advanced wiping softwares via PC. For flashing CWM or a CWM enabled kernel please visit your phone's sub-section on XDA. You must flash CWM on your phone, mot only to try the wipe but also to make a backup of your phone's image in case it gets corrupted and you need to restore it

Tried this on an Htc Magic with clockwork recovery installed. tried to format /sdcard but got error:
"error mounting /sdcard!
skipping format...
done"
tried also partitioning sd card but got error too.
and btw the previous filesystem is exfat so that is why it can't be mounted in android.
anyway also tried formatting in gparted and macintosh. both failed.

hope someone already solve this problem.. .
or else my 16gb micro sd will be gone to waste
I tried all of the possible things on the net.. .

The camera suggestion (formatting after putting in a digital camera) did the trick for me, good idea! It gave me a new set of DCIM folders, but I can pop it into my PC now and just delete them. Seems ridiculous that my camera can do it but my PC can't.

o3d goes into recovery mode every time it boots

Hi guys, i'm in desperate need of your help. i think my precious o3d might have been screwed.
first let me tell you what i did. as you know the internal sd card of o3d is 5gb or so and it fills up very quickly. this internal sd card is mounted as /sdcard. i have a class 10 16gb micro sd card and when i insert it, its automatically mounted as /sdcard/_ExternalSD. The applications or games, especially the ones that have external data folders which are like 1gb in size insists to be installed on /sdcard. You can't move those data folders to _ExternalSD, because then the apps doesn't work.
Then i came across this topic:
http://forum.xda-developers.com/showthread.php?t=1189701
As you can see that was exactly what i needed. I had CWM 5.0.2.0 installed so i downloaded the first .zip then copied all of the files and folders excluding the _ExternalSD folder to the external sd card then rebooted into recovery. From there i flashed the zip and rebooted again. phone booted up and all was ok and it worked. now the phone sees the external sd card as the internal one and the internal sd card was mounted as /sdcard/_ExternalSD. I then formatted the internal sd card from the settings menu because i already copied all of the stuff there to the external card. It worked fine and the internal card is formatted. After that i decided to get a nandroid backup so i opened the rom toolbox program. From the menus i selected the backup option, gave it a name, clicked ok. the phone rebooted into cwm recovery screen but nothing happened. then i noticed something was not right because there was some error lines under the cwm menus saying "E:can't mount CACHE:recovery/command" etc. Then i selected the reboot phone option but the phone rebooted right back into the CWM recovery again!! At that point i knew that i was @#?^ed.
Anyways i researched a lot and came across this thread:
http://forum.xda-developers.com/showthread.php?t=1156549
i did exactly what he said and it worked, i mean it flashed nicely. then i rebooted the phone but it booted into the recovery again!!! But this time the CWM recovery was gone and i believe this is the stock recovery screen. I can browse the menu of it and make selections but the phone boots into the recovery every time it reboots.
The recovery screen looks like this:
http://farm8.staticflickr.com/7010/6654644033_b616bc0635_z.jpg
Then i flashed the phone to the latest official firmware V21A_00, it flashed nicely but it still boots right into the recovery everytime.
Then i installed the Android SDK and tried to push the original vold.fstab file to the system using the adb command line tool but it doesn't see the phone. I think adb works only when the system boots up normally, not in the recovery mode.
I don't know if there's a way to install the CWM from the stock recovery somehow. If you know how, please tell. The CWM has more options.
I don't know what else i can do. It started to look ridiculous. If there are any experts cool enough to help please do so. I'll be waiting. Thank you...
Edit:
I also tried this:
http://forum.xda-developers.com/show....php?t=1244490
I starts just fine but get's stuck on the "RESET" command, after a while it gives "DOWNLOAD FAIL!" error. I think the phone is supposed to restart automatically but it doesn't. Manually resetting the phone doesn't work either.
I'm about to pull my hair out...
Edit 2:
I also posted on the official LG Mobile forum here:

Fingers crossed

Quite a post!
From all your post there is no mention that you formated and did a factory reset after 21a flash.
Can you please try that if you haven't?

thank you for the reply!
i tried all 4 wipe options on the recovery screen then rebooted. it's the same, i'm back at the good old recovery again

Did you try with the external sd card out?
This is strange, usually a kdz flash coupled with a format fixes the problem.
Some how it still can't find the internal SD card.
I don't have further recommendations. Sorry

Hopefully someone else on this forum can suggest a way for you to unbrick.
your problem is although you have reset your phone, somehow it can't find a partition to boot from.
or
somehow the KDZ flashing is not totally successful.
good luck

If only there could be a way to be able to use the adb command from the Android SDK then i might be able to restore the vold.fstab file to its original, if the problem is that at all. Maybe then it'll work. To be able to flash the CWM Recovery again somehow might be a good thing too because it has more options like flashing .zip format roms but i have no idea how. Does anyone know if the stock recovery can flash some specifically named file to the system, does it have that kind of functionality? I'm desperate, please share your thoughts.

.............anyone?

I am sorry to say that but there is no solution for this problem yet. I have done the exact thing that you do and tried every single solution with no luck. The only way is to send it to lg repair service. My solution was to replace the mainboard.
Dostum gecmis olsun malesef tek cozum yolu anakarti degistirmek. Uzaman sayilirim android konusunda bosuna ugrasmayasin diye soyluyorum. LG servisi bile anca anakarti degistirerek cozum sunabildi. Temel problem internal karti formatlamis olman. Partititon table'i bozuyor bu islem malesef ve bu yuzden hicbir yontem ise yaramiyor.
Gecmis olsun tekrar...

so you say that the main problem was to format the internal sd card? well if formatting the internal sd card bricks the phone then why the hell is there an option to format it in the settings menu?

well if you didn't apply the swap fix, it wouldn't be a problem to format. When you swap the sd cards and format, it is the problem.

so you did exactly the same thing as me right? i mean you applied the swap fix then formatted the internal sd?
replacing the motherboard to fix this seems to be a bit nonsense to me to be honest. what does the partition table have anything to do with the motherboard?
if only there would be a .kdz format custom rom which factory resets the internal sd card during the flash process and maybe fixes the bootloader somehow, that might be the solution.

yes i did the same and the only solution was to replace the motherboard. we need a sowftware that can reach to the emmc in low-level. like omap flasher. but we also need the correct drivers which doesn't exist yet.

i don't know what the emmc is, i need to do research on that. but i still think that replacing the motherboard won't solve this issue because it seems non relevant to me. i messed up with the vold.fstab file. but after that it worked fine. i mean the internal and external cards swapped just fine. only after i decided to make a nandroid backup using rom toolbox all hell broke loose. i plan to wait a couple of days before turning the phone to LG service. i believe someone will come up with an idea.
yardım etmeye çalıştığın için teşekkür ederim bu arada

Well, there´s a new recovery for the O3D, v5.0.2.7 (I got it with ROM Manager).
It fixes 2 bugs of the previous (5.0.2.0) version: now the USB mass storage option in the mounts menu works (mount external SDCARD), and we can use ADB while in recovery. That way we can fix stuff in the phone filesystem while in recovery: we can now use ADB shell, or ADB push to replace files.
The problem is that I don´t know how to flash it to the phone while in the stock recovery. If someone can guide me on creating a signed ZIP containing this new recovery, flashable in the stock recovery, I would be glad to do that and post it here. I think these phones of you guys can be fixed using this method!

Great news! But now i need to find a way to install the new CWM. Just as you said i believe what i need is to find or make a .kdz update which includes this new CWM.
What do you think?

I know this is possible, at least for the Galaxy Ace: I have a ZIP file for this device with a custom recovery image, flashable in stock recovery!
To make one for the Optimus 3D, I need to know the following:
- How can I obtain the .IMG of the new recovery? I have found some temp files in clockworkmod folder in my sdcard. The creation date of one of them matches the exact moment I upgraded my recovery, and the file size also matches a recovery image: 5.54MB. Is it the recovery image? Can I just rename it to recovery.img? How can I extract it to ensure it´s ok?
- After I get the recovery image, I can use the Galaxy Ace ZIP as the base to build the O3D zip file. Any help on what do I have to change to make it work correctly?

Edit: I'm 99% sure that this isn't a hardware related problem. And LG's software not being able to turn the phone to stock is totally [email protected]#$%!

On some "unbrick your optimus 3d" threads i came across this image:

i tried all methods around here but not once i came across a screen like it. weird...

How to install firmware on external sd

i have internal SD corruption. Everytime i boot my phone, it shows me loads of application errors. Internal SD cannot be formated and everytime i try to install new firmware it says that everything is OK but it boots to old firmware again.
I saw a guide of how to change sd to emmc by modding vold.fstab but there is nothing about changing system from sd to emmc. So i need to find out how to do that. I think its about modding init.rc but i dont know exactly what to change. Can anyone help me?
P.S. Sorry for bad eng

[Q] Swapping SDcard from external to internal gone wrong.

I have a rooted and unlocked C2104. I tried swapping external and internal and ended up changing mount points that is my phone now recognizes my microsd card as internal. Now since the microsd card does not have bootloader and other nand files, it does not recognize it when i use power button. I find only 2 solutions throughout internet:
1: To replace the motherboard.
2. To make sdcard as internal and install bootloader into it to make the phone boot from it and then flash ftf via fllashtool.
I dont know if it can be done, but if anyone can please give me the size and mountpoints of nand partition then i think i can pull it off. Help me please.

If I explain a bit more than what you did maybe I can help. What program did you use, or give me the link to the tutorial you read.

Well i didn't use any app. I just swapped the lines in vold.fstab located in /system/etc.
But on the first swapping i.e. replacing sdcard0 by sdcard1 the phone booted fine and swapped external with the internal but did not show the new external. So i cut the "emmc" before sdcard 1 and placed it before sdcard0. Thats when the system stopped responding. Now what i understand is if i can make the same partitions in an sdcard, i should be able to atleast get my power button to respond. But i dont know the partiton table of the internal.. Can u help?

Let me see if I understood ... The phone does not turn on? not connected or fastboot flash mode?

you can again revert back as it was before in vold.fstab so you'll get back your normal os.
If it doesn't work or you are unable to power on your phone flash stock ftf. Everything should be fine.

The phone does not turn on, neither does it gets connected in flash or fastboot mode. so i cannot use adb or flashtool. It only shows the notification light when i connect the wall adapter.

i think, your phone was "dead boot", and only service centre can repair it
my friend doing like youve done, but in my country, sony service centre reject the guarantee becoz hw missing(TA partition not found he said emmc was empty, yeah my friend try to format internal n external sdcard while vold.fstab swapped)
swapping vold.fstab on stock rom doesn work and it dangerous
only few phone from sonyeericsson like x8 can repaired with JTAG
sorry my English bad

so what I am asking for is, Can someone help me port / find good recovery for it ? or at least explain what should I do.. etc.. ?? ^^' .. I'd be grateful.

You don't have to have an SD card slot to use CWM. If you can get CWM installed, use it, it can flash files from your internal storage, it doesn't require an external SD card.

That is what CWM labels the internal storage, if you had an external sdcard in, it would be called sdcard1 and would show an option to flash from sdcard1.
It gets confusing sometimes but not all android software labels internal and extetnal sdcards the same. Some label internal memory as "sdcard", some label external memory as "sdcard".

No, not weird. It would say that because it can't mount your internal storage. And that would mean that it isn't working correctly and would not allow flashing from internal even if you had stuff stored on it that could be flashed.
See, you aren't understanding that the term "sdcard" does not always refer to an external sd card. Android devives use solid state storage, the internal storage on android IS a sdcard, it's just a permanent one instead of a removeable one.

I'm not real familiar with the process because I'm not an MTK user, but that can be fixed by changing a few parameters during the build/port process.
It involves adjusting the size of your recovery partition to fit the size of the file.
Similar to what is discussed in the thread linked below, it might not explain it well but it gives you the idea of the issue and how to fix it, you might need to look for other threads that discuss the solution in order to get it working for you. I'm just trying to get you pointed in the right direction, whether I can find your specific answer or not.
