Glenn, do me a favor. Get a copy of your /dev/block/mmcblk0p8. As superuser:

dd if=/dev/block/mmcblk0p8 of=/mnt/sdcard/modem.bin

I believe this is the "radio" image.

adb pull that modem.bin file over to your machine, and if you can, get an md5sum of it. I get:

6a651ae302bde5ad97f445608a655ab9 modem.bin

This is for the original 4.0.3 contents of that partition, with cm9 installed (which should not have altered it). if your 4.0.4 version of this partition has the same checksum, that means it was not altered by your installation of 4.0.4. It'll be good to know.

BTW, here are the first few lines of bytes from that file (done with od -c in Linux):

[Galaxy Tab 2 10.1" Android Development] LavaJoe:
For anyone out there who has installed (via OTA or KIES) the 4.0.4 release and then rooted, if you could grab me the "modem" image from /dev/block/mmcblk0p8 using dd (as above) and md5sum it (or better yet send it to me - PM me in that case, first), that would be much appreciated. I am curious if this got updated from 4.0.3 to 4.0.4.

If i want to root my tab i MUST have an external sd card?
[Galaxy Tab 2 10.1" Android Development] weltwon:
External SD card IS required to Root

As it says in OP post:

IMPORTANT: Copy cwm-root-gtab2.zip (or cwm-root-gtab2a.zip) to the ROOT of your external sdcard ( /mnt/extSdCard ).

This is the micro sdcard you insert in tablet slot.

Your /mnt/sdcard folder is internal memory (not recognized in CWM recovery).

Unable to update from 4.0.3 to 4.0.4

I followed the root instructions here after having upgraded to 4.0.3.

The last few days its been nagging me about the 4.0.4 update (which it automatically downloaded). Today after make a precautionary CWM backup, I tried to accept the update (while still rooted). It ended up booting into CWM and it showed the following:

What should I do to update to 4.0.4? Do I use the CWM option to disable signature verification and try again (ignoring the signature verification failure?

Note: I have the Wi-fi only model (GT-P5113).
[Galaxy Tab 2 10.1" Android Development] nitr8:
There is no need that you have to have an external card! You can use exactly the same procedure just by placing it on the internal memory...
[Galaxy Tab 2 10.1" Android Development] weltwon:
Updating to 4.0.4 AFTER you rooted while on 4.0.3

Over the air update doesn't work if you have a custom recovery (such as CWM 5.5.0.4) installed.

Easiest solution to updateis by installing the update by ODIN or through CWM using a zipped update file.

Both update file formats with instructions can be found on other threads in Development Section.

Easiest one to use if you have GT-P5113 is the one by nitr8 HERE

P.S. The 4.0.4 updated ROM runs so well, I've yet to find any reason to even try another custom ROM (at least for the last 4 days) !

[Galaxy Tab 2 10.1" Android Development] wd5gnr:
A little off topic for this thread but the sounds is in /system/media/audio/ui folder and named TW_Touch.ogg. There is also a S_HW_Touch.ogg file. If you are rooted you can change it. Anyone have the old TW_Touch.ogg from 4.0.3?

Update:

Ah, here you go: http://xdaforums.com/showpost.php?p=27447853&postcount=1

Get those two files and try this (assume you are rooted):

adb push TW_Touch.ogg /sdcard/TW_Touch.ogg
adb push S_HW_Touch.ogg /sdcard/S_HW_Touch.ogg
adb shell
su
mount -o remount,rw /system
cd /system/media/audio/ui
cp TW_Touch.ogg TW_Touch.ogg.original
cp S_HW_Touch.ogg S_HW_Touch.ogg.orginal
cp /sdcard/*_Touch.ogg . # really? You have more files named this?
rm /sdcard/*_Touch.ogg # ok then don't do this if you do!
exit
exit

Now turn touch sounds off and back on (or just on if they were already off).

Anything you install via ODIN changes the download counter.

Unless download counter says ZERO, Samsung warranty is void.

Currently, NOBODY has created a solution to reset the download counter on Tab2 10.1

Installing files via CWM does NOT change the download counter.

Are you sure you are booting to stock recovery and not booting to the bootloader screen? Recovery is holding down the volume closest to the power button while turning on. Bootloader is the other volume button.

Did Odin give indication that it succeeded? Have to flashed and then immediately booted to cwm since some upgrade scenarios replace the recovery on each boot apparently (have to get rid of install_recovery.sh or repurpose it as mentioned at http://xdaforums.com/showthread.php?t=1772616

Based on testing with my GT-P5113, the tablet runs better with stock 4.0.4 ROM than it did with CM.

NOTE TO ALL: 4.0.4 update may not be available for all regions and for all 5100, 5110 and 5113.

Check with sammobile or use KIES to see if Samsung has an update for your tablet.

[Galaxy Tab 2 10.1" Android Development] weltwon:
Using a 4.0.4 update that is NOT for your device

If KIES says there is no update for you, you're taking a chance using any other 4.0.4 update.

Furthermore, without KIES your only options for installing an update are via ODIN which DOES change the download counter

or rename whatever update file you find to update.zip and trying to install it via the stock recovery mode. If stock

recovery rejects the update, you would have to install CWM from this OP (via ODIN) which will also change download counter.

Weltwon -

I would suggest stating something in the OP about removing the install-recovery.sh script, as it kept keeping me from being able to install a custom recovery image... kept taking me back to the stock recovery each time.

Once I moved it from the system to the SD card, the heimdall flash recovery took, and hasn't given me problems since.

I have not had this problem myself and I think it stems from folks who revert to stock and then do the OTA update maybe? However, I take over install-bootloader.sh for my own purposes (http://xdaforums.com/showthread.php?t=1772616).

What I have noticed is the 6.x version of CWM when you reboot will ask you something like "Your ROM may install the stock recovery when you reboot. Fix?"

So one answer is to install CWM 6 and then be sure to boot into CWM FIRST. Then it will remove the install-bootloader.sh file. Of course, if you are using my init.d hack, don't do that, but after an update that will be blown away.

Simplest solution might be to advise anyone who receives a new Nexus 7 that comes with 4.0.4 pre-loaded

CWM for tablets that come with 4.0.4 installed

Sounds like some of the people receiving new tablets that have 4.0.4 installed are having a problem that prevents using the root procedure in my OP so I am going to add a note accordingly until we have a definite solution.

For those who receive a new tablet running 4.0.3 :

ROOT your tablet BEFORE you install 4.0.4 update

via CWM5 or CWM6 you won't lose access to CWM.

Root 4.0.4 workaround

I had the same problem, because I had already taken the 4.0.4 update. The problem I (and I suspect the others) were having is the reboot after Odin installs the CWM. It happens so fast, there's no time to unplug the tablet and do the button dance to boot into recovery. As a result, the normal boot goes through, and runs the install-recovery.sh that Ryan79 mentioned in system/etc, restoring stock recovery.

Here's how I solved it: On Odin, uncheck "Auto Reboot". Install CWM6. When it goes green, unplug the tablet (still in "download" screen). Reboot manually into recovery (hold power + Vol. left, release power, hold vol. left until CWM screen comes up). I did this straight from the "download" screen. The tablet powered off after a few seconds of holding the power button, then came up to the samsung screen, then I released the power button and continued to hold the volume button until CWM6 loaded. I installed the cwm-root-gtab2.zip file. I selected YES

when the "Stock Reboot Fix" question appeared. Rebooted from recovery, Successful root! Looks to me like the "fix" simply renames the install-recovery.sh, removing the ".sh" at the end. I have now rebooted a couple of times normally, and can still access CWM6 through the buttons.
