[Galaxy Tab 7.7 General] PeFri:
Took the risk - Success, at last!

Since I did not get any more helpful answers, I had to reconsider the situation. Finally I decided to take the risk by using a best of

a) the xda-developers [GUIDE] Root (Updated for ICS)

, e.g. postings #1 by Jade Eyed Wolf, #213 by kable, #227 by ronnieho, #230 by mashkuov, etc.

b) aljee77 guide for the SGS2

Trusting that the xda-developers zip-files, CWM.zip and root.zip, will be ok for the Tab7.7

and hoping that the aljee77 procedure will also work as well for my Tab7.7 as it has worked for my SGS2,

I took the risk and finally succeeded to root my Tab7.7. :)

My successful procedure (Thanks to aljee77 and mashkuov):

1. Data preparation (zip-files)

1.1 Downloaded CWM.zip and root.zip to my computer from mashkuov, post #230 in http://xdaforums.com/showthread.php?t=1454112&page=23

1.2 Copy these zip files from my computer to respective sdcard in my tab.

I have the Samsung Kies drivers installed on my computer. But I do not use Odin. I connect the tab and the computer with the USB data cable and simply use the USB MTP connection. I simply copy the zip-files like I would copy video and audio files by simple Windows Explorer file-drag/drop between the the source/target location icons.

1.3 I copy CWM.zip into my _external_ SDCARD

(on the computer: GT-P6800/Card

on the tab: /sdcard/extStorages/SdCard)

1.4 I copy root.zip into my _internal_ SDCARD ( /sdcard/ ) <--- aljee77 procedure <--- :good:

(on the computer: GT-P6800/Tablet

on the tab: /sdcard/)

2. Temporary installation of CWM Recovery:

- Reboot to recovery:

2.1 Download and install LATEST SAMSUNG KIES (or stand-alone USB drivers if you can find them)

2.2 Transfer CWM.zip to the EXTERNAL CARD on Galaxy Tab 7.7 (already done in step 1.3)

2.3 Turn off the Galaxy Tab 7.7

2.4 Enter Recovery

- Hold Volume UP button + Power Button

- When TAB turns ON, RELEASE POWER BUTTON (Keep Holding Volume UP Button)

* Will Enter Recovery

2.5 In the following basic menu use Volume Up/Down to navigate and Power OFF to select/accept options!

- Choose apply update from external storage.

- Choose CWM.zip and wait until CWM recovery appears.

* Now a temporary CWM is installed and activated.

* This CWM recovery is only a _temporary_ CWM and will be gone after reboot!

* see #217 by vegaman: http://xdaforums.com/showpost.php?p=28300775&postcount=217

3. Install root

* Once the CWM recovery appears:

* _Touch-screen_ to navigate and to choose an option!

- install zip from sdcard (1st CWM menu)

- choose zip from internal sdcard (2nd CWM menu) <--- aljee77 procedure <--- :good:

- toggle signature verification & script asserts to disable <--- ronnieho #227 http://xdaforums.com/showthread.php?t=1454112&page=22

- +++ GO BACK ++++ (from 2nd to 1st CWM menu)

- reboot system now (1st CWM menu)

* After reboot your tab will be rooted and temporary CWM will be gone.

4. Enjoy!

Now the tab is rooted! Temporary CWM is gone.

Now you can download Superuser App and Superuser Elite App (both by ChainsDD) from the market.

5. If you want a permanent CWM see #220 by Handymeister: http://xdaforums.com/showpost.php?p=28319010&postcount=220
