[Galaxy Tab Q&A, Help & Troubleshooting] kminusone:
I wasn't able to unpack it in cm11 rom. It says the same, there is no magic android header.

I am able to do the following:

DOWNLOAD MODE (turn off, volume down + turn on)

RECOVERY MODE (turn off, volume up + turn on)

- Format 16g memory card like this (e.g. with miniTool Partition): | sdcard,primary,fat32,~5000mb | data,primary,ext4,~1800mb | preload,primary,fat32,~200mb |

(with bigger cards, obviously bigger sdcard and data partition)

- DO NOT format sd with inserted in tab, and mounted in recovery; it will make partitions INSIDE of mmcblk0p1 block, not 3 blocks, mmcblk0p1, 0p2 and 0p3. So, DO format like in laptop, with microSD>SD transformer

- Insert SD card to TAB

- Flash gt-p1000_mr.pit and GB_Stock_Safe.tar with odin 3.07 (the only one which can push hidden.rfs, or skipping it automatically, like ignoring it in heimdall)

- Reboot in recovery mode, see that it can't see int. memory

- Reboot to download mode, flash overcome kernel

- Reboot to recovery, connect to adb, and now you can "adb pull /system/etc/vold.fstab"

- The file pulled to the adb folder should be edited to this (got this from a tutorial):

# 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
#end line ## keep this line

- Now type in adb: "adb push vold.fstab /system/etc/"

- To check out booting, type in adb: "adb logcat".

- Reboot your device.

- A female robot voice tells you not enough space on system partition, converting it, estimated time 2 mins, etc etc.

- After a while you should see many-many lines written in adb window, and see your tab booting.

- When turned off charging for 1st time, don't worry, it will convert something again, female voice will appear again. Never so again.

- Now you have your tab working camera, sdcard, apps, etc.

STOP HERE? IF YOU WANT A WORKING 2.3, CONTINUE IF YOU WANT A HALF-WORKING CM11.

2.3 is outdated, I tried to update to cm11

- Go to overcome recovery

- Recovery detects sdcard0 and sdcard1 normally.

- (I didn't do any wipes o.O)

- Flash cm11.

- It will reboot to clockworkmod recovery.

- NOW FCKN recovery detects external sd partition 1 (your savior) as sdcard 1, FUUUUU!

- You have to flash the zip file again.

- Flash gapps. Because of "missing" (it's just mounted in the wrong place) sdcard partiton, some of them can not install.

- Now system boots, you can install apk-s. But even if you umount and mount the sd in the good place, camera and market sd-required apps won't work. So like fb, messenger, circle don't need them, so they work. BADLAND, Real Racing, won't, they need the sdcard mounted in place by the fstab file. You cannot download files in stock browser, neither in Dolphin, only in CM Browser.

Choose, you want to use an older, working os, or a half-working, but newer os, with more (cm features)

Maybe I will include the programs I used, when XDA allows me to place links in this post.
