here it is

since we have no forum yet (um come on mods get to it!) I can't post a shiny new thready for my very first real dev, ROOT FOR YOUR GALAXY TAB 2 7.0!!

so I'll put it in this post, and I'll mention I posted this on rootzwiki first, we have our very own forum there... (XDA I love ya, and I know you will get there hehe)


** Edit ***
I just attached the files as well as mediafire, rename the txt file to pit (xda won't accept the file as is..

Method

I have gained root through using a modified boot.img from the gt-p3110 leak posted a few weeks ago, took me all day but here it is.

Note I haven't only tested this on my device, its 2am est and all my testers are asleep (that being termitech lol)..

Standard YMMV
So big fat warning, I MAKE NO GUARANTEES THIS WILL NOT BRICK YOUR TAB, USE AT YOUR OWN RISK!!

Now with that unpleasantness out of the way.. with out further ado. I present the very first root for the Samsung Galaxy Tab 2 7.0!! Yay mom I'm a dev now!

The method will have you using hemidall/heimdall-frontend there is a way to put this all into an odin package but I'm too exhausted to do so (for now).. Also I will not re-hash how to install or use heimdall.. you can look that up on your own

Get it here:
http://www.glassechidna.com.au/products/heimdall/

Process
Once that is installed do the following:
  • reboot tablet into download mode
  • adb reboot download

  • launch heimdall-frontend
  • go to flash tab
  • load attached pit file (gt-p3110.pit)
  • Then from partion details choose "KERNEL", click "Add"
  • then choose "Browse" and select the attached boot-bjr.img
  • choose "Start"

after the tablet reboots:

Code:
adb shell
./su
./gtab2-root.sh
Congratulations you are now rooted!

I'm going to try and stay up a bit longer and monitor this (and the xda thread) please let me know immediately of success or failure, I will pull the files if failure.. Issues with heimdall aside, I want reports back on if things work.. They work for me.. and I tested a fresh factory img just a few minutes ago.. pretty sure we are good!

Flash xoomdev's CWM recovery First, then flash the package in this post.

Xoomdev's thread

Paste of his instructions:


Download the recovery.tar.md5

Make sure Kies is closed
Reboot into Download mode (adb reboot download)
Open Odin, confirm connection
Click PDA
Load recovery.tar.md5 file
Click Start
Device will reboot when the flash is complete

To reboot into recovery, just like any other device; adb reboot recovery

Link to the CWM Package

Link to root package

Congratulations you are now rooted!

Thank for making this possible!

I followed these directions exact. But, I am getting the following error - E:signature verification failed - when updating 'cmw-root-gtab2.zip'

I did run that Samsung update on the device last week when it was first powered on @ BB - could this have any issues with the root process?

I have tried doing it this way 5x now, and when I try to use Odin, it loads the recovery.tar.md5 file, I click start, then I get what i linked below


I dont know what I am doing wrong. I am in the download mode


<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> recovery.tar.md5 is valid.
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..
<OSM> All threads completed. (succeed 0 / failed 0)


That is what I get since you cant see the picture very well.

Try to redownload the file, also try hiemdall instead.. and check out the thread on rootzwiki until more gets posted here, the issue is with flashing cwm, not the root.

Also did you reboot after flashing and try to access recovery mode?

My tab doesnt reboot after the flash, its like it never even happened.

I tried the heimdall way, but the img file cant be found anywhere at the moment.

I am new to the android world, so bear with me. I followed the exact steps for this one that you posted, and my tablet acts like nothing even happened.

Pretty sure you need to follow the thread over on rootzwiki called "Stopping recovery overwrite" in the Galaxy Tab 2 (7") Development forum. After that use ODIN to flash CWM. You need to do this if the upgrade was applied to your stock tab (UEALD3 / SEP-66 #1).

If you follow the instructions it will work. If you get a signature error, you are NOT on CWM. Look at the top of the screen, if do you not see Clockwork Mod you are not using CWM you are using 3e recovery which is the stock. Start over and flash CWM.

Once you have CWM flash the root package. You should then be all set. I've done it a dozen times now and it worked every time.

Yeah, when i opened it it updated. So that may be the issue then?

I think I royally F***ED my tab up...

I'm stuck at the boot splash screen with "ABORT IN SBL" in the upper left corner.

I can't get it to boot to recovery. I can only get it to boot into the download mode now.

Is there any way to flash this back to stock using heimdall on ubuntu?

Please dear god tell me there is a way to fix this.

I think I am just going to give up on trying to root this thing till an easier solution comes out.... I cant get this thing to recover back to the stock shipped software.

There will likely never be any other solution. You will always have to flash recovery in Heim or Odin. After that you can flash a rooted ROM. But there will always be that initial work.

I will see if I can find a stock firmware package, but it will be the same type of flashing.

Error flashing Root files through CWM...

I odined the recovery and now I have CWM. But when I try to flash the Root file (through install zip from sdcard) it says:
E:Can't mount /sdcard/
Do I have to have an external SD card or something?
What should I do?

Edit: I mounted an external Micro SD card and it worked flawlessly. Please add this mote in the OP, thanks a lot...

Yes, clockwork uses an ext card.
