Thumbs up [Guide] Samsung P1000 with a corrupt internal sdcard - Solution here

I recently fixed a P1000 with a corrupt internal sdcard - I thought I'd share my experience.

The Symptoms

When Booting the device got stuck at the Samsung Logo Screen
ODin/Heimdall fails on any rom which include an hidden.rfs and movinand.mst
ODin/Heimdall report success when flashing flashing roms without hidden.rfs and movinand.mst
Recovery Mode reports errors after flashing. The error is different depending on which rom was flashed but are all related to file system functions.

Internal MMC checksum verify failed.
E: failed to mount /system (invalid argument)
E: failed to mount /dbdata (Invalid argument)
E: /dev/block/mmcblk0p2 on /data failed: No such file or directory
E: copy_dbdata_media:Can't mount /dbdata

The Problem
The recovery errors alone are not enough to diagnose the problem as they can also occur if flashing has been carried out incorrectly.

The main pointer to an Internal SDCard Failure is the inability to flash hidden.rfs and movinand.mst
You should be able to confirm this to be the case by running dmesg on the device using adb from the command prompt
Code:

adb shell dmesg

My output contained the following line:
Code:

<3>[ 4.802004] mmc0: error -110 whilst initialising MMC card

The Solution
Normally you should be able to RMA this as it is an hardware failure.
However as warranties expire or you just can't be bothered to wait here is an alternative solution

1. Format the external sdcard with 3 parititions (you can probably get away with 2) I used a 32 GB card with the follwing

Partition 1: 28 GB Fat 32 (sdcard partition)
Partition 2: 4 GB ext4 (data partition)
Partition 3: 100MB Fat 32 (preload partition)

If you want more space for app, make the data partition larger

2. Flash Latest Rom. I used XWJQ8 but I also flashed XXJPZ Successfully and I don't think it makes alot of difference

I Used Heimdall for this and I flashed everything. Odin should do the Job as long you remove hidden.rfs and movinand.mst from the tar balls

Code:

heimdall flash --repartition --pit gt-p1000_mr.pit --primary-boot boot.bin \
--cache cache.rfs \
--factoryfs factoryfs.rfs \
--modem modem.bin \
--param param.lfs \
--secondary-boot Sbl.bin \
--kernel zImage --recovery zImage


3. Flash latest Overcome Kernel 4 which can be downloaded from the teamovercome download page

4. Boot To Recovery ( You should now see Clockwork Recovery Mod )

5. edit /system/etc/vold.fstab on the device to look like the following

Code:

# internal sdcard
{
ums_path = /sys/devices/platform/usb_mass_storage/lun0/file
asec = disable
discard = disable
format_option = -r 1558
}
dev_mount sdcard /mnt/sdcard 1 /devices/platform/s3c-sdhci.2/mmc_host/mmc1

# externel sdcard
{
ums_path = /sys/devices/platform/usb_mass_storage/lun0/file
asec = enable
}
dev_mount sdcard /mnt/sdcard/external_sd auto /devices/platform/s3c-sdhci.2/mmc_host/mmc2 /devices/platform/s3c-sdhci.2/mmc_host/mmc1

6. Reboot, System Should now functioning normally.

Note: First boot takes a while. if you are worried or think it is boot looping, you can watch the output using adb logcat

You should now have a working galaxy with the added bonus of a re-sizable data partition.

Hello everyone, I have an galaxy tab gt-p1000 with the symptoms you describe. I am convinced that the tablet have a hardware problem.
Googling i found this thread and see a light in the end of the tunnel.
I managed to make the steps 1,2,3,4.

Step 1:
I use yhe software minitool software Partition Home, that is free.
The card only have 8Gb but I sized the partitions:
Partition 1: 3,5GB GB Fat 32 (sdcard partition)
Partition 2: 4 GB ext4 (data partition)
Partition 3: 100MB Fat 32 (preload partition)

Step 2:
I flashed with odin the GB-Stock-Safe-v5, Removed the files hidden.rfs and movinand.mst from the .tar file and flashed sucessufuly.

Step 3 and 4 no problem.

Step 5:
Pressed Power button an volume up and enter de recovery mode of the overcome firmware.
And now ??? How do I Edit the file "vold.fstab".
How can I do this in the recovery mode ? How can access the file and manage to edit it like you describe.

Thanks in advanced

Thanks for the reply. Sory for my bad English.
The point 5 says: "5. edit /system/etc/vold.fstab on the device"

You say I can use winrar. How?
Conect the device to the computer and search for the file ?

If so something is wrong because the device its detected but when I try to explore de drive it says to format it.

Please help me, Samsung Service asks me for 250,00Euros to change the mainboard, they ara insane.

Thanks a lot, my tab it's working again.

I don't know the adb software. The process of changing the file it's quite simple whem you know it.
After I read this thread:
[GUIDE] ADB Workshop and Guide for everyone - xda-developers

In recovery mode, tab connected with usb, open comand prompt, use adb commands Pull the file, changet it with notepad++, and the then command push the file. Reboot the tab and it's back alive.

Fu*k Samsung Service, they try to charge it 250Euros.
