Yea, I forgot to install 'superuser', as it appears SuperSU is busted or something... wasn't until I went back that I realize that I needed to install a different su binary... weird having two SU programs on one device.

It's a shame TWRP isn't available for the Tab 2... I've used CWM forever, until I had to put TWRP on my Prime 201... TWRP is a beast....

Thanks to everyone for a super easy way to gain root... much simpler than getting nvflash on my Prime or rooting my Toro Galaxy Nexus...

Before any of you decide to try the 7" touch CWM on your 10.1,

be advised that when I tried it, it nearly bricked my Tab 2 10.1

so YOU HAVE BEEN WARNED.

Well im no dev but im sure ill be on Google later trying to find a guide on it
[Galaxy Tab 2 10.1" Android Development] LavaJoe:
I find this very curious, as I did not have this issue. I just today upgraded my GT-P5113 to stock 4.0.4. Since I had CM9 installed, I did a nandroid recovery of my old stock 4.0.3 (which resulted in an unroot), and then I used Kies to install 4.0.4. All went well, and the unit then booted, now unrooted, into stock 4.0.4.

I then re-flashed CWM 5.5.0.4 using heimdall with the --no-reboot option (to prevent booting into the stock ROM). However, I accidentally booted into the 4.0.4 ROM, anyway. I fully expected that doing this would revert my recovery, but it didn't. Rebooting back to recovery (I did it via "adb reboot recovery") took me back to CWM, to my surprise and delight. :)

I then re-installed CM9, and things are looking good.

FYI: Note that I dumped the new partitions that the 4.0.4 would have upgraded and found that the BOOT, MODEM, and PARAM paritions are unchanged, whereas the KERNEL, and HIDDEN ones are changed. Not surprising, really, but now we know that the MODEM firmware is identical in 4.0.3 and 4.0.4 (I had wondered - as I said in a previous post - if they had updated the radio firmware to, e.g., improve wifi (if the MODEM partition has this function - and I am not sure of this), but alas, no).

So just another data point - not sure why I had no issues upgrading to 4.0.4 (unrooted) and then re-installing CWM without the issues some have seen.

[Galaxy Tab 2 10.1" Android Development] Daagen:
I guess its not cwm flashable. Unzip it and flash it via odin.
[Galaxy Tab 2 10.1" Android Development] lgladen:
The main difference would seem to be the use of Kies - as I had taken the 4.0.4 as an OTA update, with the (slightly foolish, I know) belief that I would still be able to root later on. Perhaps that is what drops the install-recovery.sh script that seems to be the culprit in the stock recovery install.

Glad the workaround was useful for some others. I'm never sure that my instructions are clear until at least a couple of people are able to follow them.
[Galaxy Tab 2 10.1" Android Development] 7drlclk:
yes, it is Odin flashable, thank you :)

now i need to re-root my device, and as i expected i need to do the #320 post method.

now everything is working fine :)
[Galaxy Tab 2 10.1" Android Development] LavaJoe:
Ah, interesting! Yes, that makes sense that the install-recovery.sh script could be an OTA-only thing...

[Galaxy Tab 2 10.1" Android Development] dimensionone:
Ok, I have read some other topics, and found out, that using CWM 6.0.1.0 can help.

I have applied it via Odin, but made sure, that Auto-reboot was not checked. Once, the CWM was applied to the tabled, I have disconnected it from USB and pressed LEFT button and pressed POWER button. Tablet was restarted into CWM mode. I have applied rooted kernel and restarted the system. I have seen that somewhere was mentioned, that kernel zip file shall be installed from external sd card only. But via CWM I could see the content of my internal card too. I have never tried it, but as soon as I see the content of internal card, it shall be possible to install from this card.

So result is - also tablets with 4.0.4 version shipped can be rooted without any problems :cowboy::cowboy::cowboy:

I haven't been able to make a backup as I don't have enough memory on my internal or external cards.

What do you get when you breed an elephant with a Rhino? ELEPHINO!

In other words, Codeworkx provided the CWMs so you can quiz him.

However, from my experience with all my other droid devices, CWM always backed up EVERYTHING.

[Galaxy Tab 2 10.1" Android Development] Endoroid:
My only other android device is a droid 3 and it only backs up system, data and cache. Given that flashing/factory reset/most any action you take in cwm leaves the sdcard untouched it seems silly to back it up
[Galaxy Tab 2 10.1" Android Development] weltwon:
Backups

I believe you're forgetting that we can move apps and create folders on the internal SD card,

all of which I most people want backed up and restored when needed.

Glenn :)
[Galaxy Tab 2 10.1" Android Development] Endoroid:
I don't get the moving apps to sd, for the amount of storage an app takes, unless you have an outrageous number of apps you shouldn't need to, plus a factory reset shouldn't affect any folders on the sd(I've never bothered with app to sd, but wouldn't a factory reset leave that alone anyways as it only wipes /data and /cache) . Granted I know the d3 works different than most devices due to the locked bootloader, so feel free to correct any misconceptions I have. I've only flashed this tab twice but nothing I did those 2 times affected my sdcard.

Edit:I see this device doesn't have a separate partition for apps, tibu shows my internal and sdcard as the same. My d3 has 2gb dedicated for that. I understand now, but it seems like poor design
[Galaxy Tab 2 10.1" Android Development] sxi200:
On all my devices which I still have S1, S2, S3, Tab 1 all my backups back everything up but not the actual data that shows on the internal SD card. By that I mean the data that shows in My Files.

This cwm backs up everything, including game data, navigation files / data, pics....everything, even old cwm backups if they are there.

My S3 is 32gb with a 32gb card as well. If it backed up this way and my internal card was full, I'd need the entire external card just for the backup. That sucks man.

Btw, only got my tab yesterday and already bought a 32gb card today. Anyway, I will try to ask Codeworks why it does it this way.

Thanks for your help.
[Galaxy Tab 2 10.1" Android Development] LavaJoe:
I'm using CWM 5.5.0.4, and its nandroid backup function does not back up either internal or external sdcard data (only system, boot, cache, data, recovery, and android_secure). Are you talking about something other than nandroid backup? If not, which version of CWM?

---------- Post added at 09:55 AM ---------- Previous post was at 09:17 AM ----------

I answered my own question... Look in /system/build.prop (found in your nandroid backup). You'll see several lines, like:

ro.build.version.incremental=P5113UEBLG5

containing "LG5" (if you, like I, have the LG5 version). Not sure if this is the 1st or 2nd July update from Samsung. Anyone have a later 4.0.4 than LG5?
[Galaxy Tab 2 10.1" Android Development] weltwon:
updates

Don't think so.
[Galaxy Tab 2 10.1" Android Development] sxi200:
Mine backs up only those as well, but data actually backs up everything on the internal card. I can tell by the size of the data file. I had to move most things off yo the external card to reduce the size of the backup.

Ok , on a 10.1 ICS tablet, (GT-5113), with USB debug enabled, I can go into the download menu, and the phone is successfully in download mode, and ODIN successfully transfers GT-P5113_ClockworkMod-Recovery_5.5.0.4.tar and turns green, device reboots,

Help!
[Galaxy Tab 2 10.1" Android Development] notoriousB:
Uncheck the option to automatically reboot in odin. Upload the cwm tar file. When the upload is completed and shows green, power off the tablet using the power button. Then immediately reboot into cwm and apply the root zip file. Do not boot into android after loading cwm, you must go right into recovery and install the root package.
[Galaxy Tab 2 10.1" Android Development] chocolatet:

[Galaxy Tab 2 10.1" Android Development] dimensionone:
This is working for sure. When you finish uploading via Odin (make sure it will not reboot automatically), disconnect usb cable, press and hold volume button (left one) and press power button several times to restart it. It will surely restart from download mode into recovery.

By the way, I have now looked more closely, and I think that the Odin that you refer to is not the same as the software that's used for flashing Android ROM's. Here's the description of the Odin software mentioned above:

ODIN description

Free software framework for rapid prototyping of magnetic resonance imaging (MRI) sequences

Therefore, for future use, I'm still looking for software for flashing a Galaxy Tab 2 (10.1) ROM that runs either under MacOSX or Linux. Heimdall might work, but the recovery.tar.md5 file mentioned here is not compatible with Heimdall.

Well this sucks it seems everyone hates our tablet. Though i dont see why the 7 inch roms couldnt be easily made to work on the 10.1. They use the same hardware save for screen. Its the same situation as the tab 10.1 and 8.9 and those could share roms by just swapping out a couple of files.

Funny thing is, the 8.9 tablet was the first to get an ICS custom ROM.

Isn't this current root method based on the 7 tab, its just a matter of time before rom's start dropping. the fact that the 7 and the 10.1 are so similar is just going to simplify development on the 10.1. just be patient. the last thing we need is this forum packed with a bunch of bricked tablets. °} :-)

Disregard above post. I got root but only after installing KIES (so windows samsung drivers were installed) evidently ODIN does not have drivers and needs KIES the KIES drivers to connect.

Lastly, I had to re-do the procedures two or three times in order to be able to get root access. Not sure why, but I'm happy regardless.

Thanks again for the simple instructions, although you may want to add the fact that drivers are needed.
[Galaxy Tab 2 10.1" Android Development] weltwon:
ODIN requires prior KIES installation

People,

For those not familiar with using ODIN:

1. ODIN is a Windows application. It does not work with Apple or Linux computers.

2. You should install (or have previously installed) Samsung's KIES software BEFORE using ODIN. In short, ODIN may require one or more drivers not found on your computer unless you have installed KIES. If anyone reading this knows exactly what KIES component(s) is/are required by ODIN, please PM me so I can add to the list of requirements on the Root instructions.

3. When using ODIN, under Option the ONLY field you should have checked is Auto Reboot

Glenn :)

P.S. If anyone gets an error code when installing anything you've downloaded, 99% of the time, it's because you didn't get a clean (complete) download. Best solution is to reboot your PC. Then with no other apps open, make sure you have a good solid fast internet connection and download the file(s) again.
[Galaxy Tab 2 10.1" Android Development] PanchoPlanet:
As far as I know (from previous experience with SGS2 Epic touch) the drivers that kies installs after identifying your specific device, Tab, phone, etc., is all that Odin needs in order for it to recognize your device. Don't think that there is anything else in kies that Odin uses to run properly. I think that links can be found for just drivers without D/L kies is some cases concerning phone rooting.

Remember seeing links for just drivers on some OP's for rooting samsung phones.

Samsung USB Drivers

If you've never installed KIES, you caan try simply installing a smaller package of Samsung USB drivers.

If you use it in place of KIES and it works, please let us know by posting on this thread.
