I suggest you use isimobile's method found " HERE !!" Don't forget to thank him!!! or we'll fallow you home and poop in your driveway!
If for some reason that does not work try my method!
Sorry Mods I wasn't sure which forum I should put this in please move if incorrect!
A little history before I continue!
I recently decided to Root my TELUS GT-P7510/16GB/WIFI so I went to the Galaxy Tab 10.1 Android Development Forum and fallowed S0ckM0nk3y's [ACSyndicate] [How-To] Root/Unroot The SGT 10.1 GT-P7510 USA Retail WiFi Only
Everything was going fine until I was to put it into Recovery Mode (At this point Its CWM-based Recovery v18.104.22.168) to Flash Samsung_Galaxy_Tab_10.1_root.zip, but as soon as it booted into Recovery the screen was scrolling as shown here http://www.youtube.com/watch?v=GhGm6...layer_embedded by castiel19.
There is nothing you can do to correct this except fallow my Guide (OR) download and install the only CWM Recovery that works for us with this problem which is ClockworkMod_Recovery_v22.214.171.124_P75xx.tar
... I have tried all of them and this is the only one that works....For me anyways!
I was not satisfied with this as I Purchased ROM Manager and it shows that the latest update for my device is V126.96.36.199, so I decided to try all I could to find a solution and I did.... By accident!
Before You continue, Please back up all your personal stuff to your PC or any other media but do not leave anything you can not loose on the TAB it will be gone if you continue!
Meat, Potatoes and Gravy!
Follow S0ckM0nk3y's Guide HERE you want to follow the Unroot part!
Click on the very first Blue DOWNLOAD link in his guide which will open another forum with a similar layout and click the first Blue DOWNLOAD link at the top of that guide save it to your desktop. The file is called sgt10.1_root_unroot.zip and it is 381MB. Once downloaded, extract to a new folder on your desktop, now open that new folder on your desktop and extract the ODIN3_v1.85.zip!
Put your Tab 10.1 into Download Mode by using S0ckM0nk3y's guide.
Open Odin3_v1.85.exe that is in the folder that you extracted the two downloads too on the desktop.
Click the PDA button and choose P7510XABKMP_P7510UEKMP_HOME.tar.md5.
Plug the USB into your PC
Plug the other end into the Tab
In the Odin Software on your PC the box below ID:COM should be yellow with stuff in it click the start button it will take a few minutes. 1min 59sec for me. once finished the Tab will reboot and do some stuff then it will reboot again to the OS.
Your Unrooted with an to up to date stock ROM!
This is optional but recommended! Power off your device now, and then put it in Recovery Mode.
Once Android System Recovery comes up click "wipe data/factory reset" then click "wipe cache partition" then click "reboot system".
Now Root using HERE and install any of the appropriate CWM Recovery versions without having the rolling screens!
I will clean this up later it is 2am and I have to Tow a car 800km tomorrow! There are fellow members that need this so it was rushed sorry!
I would like feedback on this as to wether it works or not for you!
I had my wife follow this guide with her Tab that was doing the same thing and it worked for her first time, but i'm more worried that my wording might not be understood by some and if that is the case it may not work for you and i would like to help you understand!
I can not confirm this but thanks to "isimobile and vladin79" it also works on 3g P7500 version!
P7510XABKMP_P7510UEKMP_HOME.tar.md5 is now included in S0ckM0nk3y's Package! Upated this guide to reflect that change.
After you fallow this Guide and all goes well but then you notice that when your screen goes to sleep then you wake it up and it is scrambled in the center of the screen and the only way you can stop it is to reboot, follow this Guide! http://forum.xda-developers.com/show....php?t=1680738
