Hello everybody, I'm new to this forum, but I'm reading it for about 8 months now. I have a problem with my Samsung Galaxy S I9000. After flashing with Odin3 v1.83(with 512.pit file, bootloader, PDA, PHONE and CSC), and I got a green "PASS!" on it, and after phone rebooted in Recovery Mode, I've got following error while Copying media files:
E:Failed to mount /sdcard (Invalid Argument)
After that, I tried flashing bunch of different ROM's but I always get the same error. Phone can go into Download mode, Recovery mode with no problem, I can also normally turn on phone and in a beggining I get a lot of "Force Close" pop-ups, but after that my phone works okay, I can go into settings and there I can see that there is no memory, so that means that my phone doesn't even sees my 8GB external micro sd card. When I try to open Camera, I get this error:
Turn off usb storage before using camera.
I currentlly have i9000XWJVZ 2.3.6 ROM on it, with CF-Root-XX_OXA_JVZ-v4.3-CWM3RFS(Clockwork Recovery v3.0.0.5). When I'm in Recovery mode and access my phone via ADB, and try to manually mount sdcard, this is what I get:
~ # mount sdcard
mount sdcard
mount: mounting /dev/block/mmcblk0p1 on /sdcard failed: I/O error
I've also tried partitioning my external 8GB micro SD card with linux(I found a video on youtube: "Samsung i9000 mmcblk0p2 error recovery"), and then tried to flash ROM on it, but I get the same error.
Can somebody please help me, I'm getting really desperate.
All ideas are welcome, Thanks.

Hi there! I have a similar problem. After updating from Android 2.3.4 Build MCGv7.6 ( I9000XXJVK) I keep on getting CWM. I can also return to download mode and use Odin with success - with as only result a changed CMW version at max. Returning to CWM 3.0.0.5 and stock rom Froyo doesn't result in a applied rom. When i try to mount /emmc and /sd-ext it simply states Error mounting /emmc! Even though I didn't format it! When I look in AROMA explorer in CWM from Semaphore_JB_2.9.12, I can see that both /emmc and /sdcard have ----- as permissions instead of rxwrx or something alike. If permissions are the problem here, Fix Permissions doesn't appear to have an effect on these two folders. Is there another way to restore these permissions?
Thanks guys for your time! :good:

Possible solution is to Format your SD card by using SDFormatter (Windows)

01. Download "SDFormatter" from the link above
02. Install "SDFormatter"
03. Enable "USB Debugging Mode" from Developer Options in settings.
04. Connect your tablet to PC (USB).
05. Then, tap the "USB Strage Mode" to connect to PC.
06. Backup data on INTERNAL_SD card.
07. Run "SDFormatter".
08. Specify the drive letter of INTERNAL_SD in SDFormatter and click "(Option)" button.
09. "FORMAT TYPE" select "FULL OVERWRITE" and set "FORMAT SIZE ADJUSMENT" to "ON" and click "OK"
10. Now click "FORMAT" and wait for the procedure to complete. (Can take approximately 1 hour 40 minutes)
11. After format is completed you can recopy the backup files back onto the INTERNAL_SD


Let me know if that works
If not hopefully someone else can give more info

This worked! :D
It took me about an hour, and after it was finished, I was able to flash ROM without any errors. Thank you so much for this, you saved my phone.

After flash dbdata.rfs.tar, it still showed same error message.

You could try changing the way you do it. I can't remember whether you should flash dbdata straight after the rom, or if you should let it fail to boot then go back into download mode and flash it.

I do remember though that it was a bit fussy with me like that, so try it both ways.

I also found that flashing your GB ROM twice, one after the other seemed to help sometimes too. (Just noticed that I've written a .txt file in my GB ROM folder on my PC reminding me to do this, so there must have been a reason for it - been a while since I've played with gingerbread so I can't remember why)

So there's a couple of things for you to try.

Thanks both of you. I will try.
EwOkie - Should I use CF-Root-XX_OXA_JVU_2.3.6-v4.3-CWM3RFS for rooting phone or others?
