[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] animatechnica:
I'm totally confused by your steps here

you went to odin mode and used adb? or did you go into fastboot and adb the recovery?

step by step here

a quick overview of it is to get your tab into ODIN mode and use ODIN to reload a copy of the stock image to your tab. This erases all of your previous data but you can reinstall those later. But at least it gets you back to a working tab - Note this is for the 7510 - the wifi tab

1) Download this file - MEGAUPLOAD - The leading online storage and file delivery service

2) extract the file

you should have the following

a file called GT-P7510_USB_Driver_v1_3_2360_0-Escape - this file is the USB driver for your PC, if you don't have the driver installed already, run this

a folder named Odin3 v1.85 - this contains the ODIN executable file

a folder named KME Odin - which contains 2 files - android_fastboot_emmc_full_p4_16G_32G.pit" and a "P7510XABKME_P7510UEKME_HOME.tar"

3) Power down the tab

4) press POWER and Volume Down at the same time until it powers up and you should see 2 logos - USB and triangle (note the retail wifi version might show 2 different logos, android on right and bag on left - left is recovery and right is Odin/download)

5) press volume down to move the selection to the triangle (or the icon on the right)

6) press volume up to lock in selection. You are now in ODIN/download mode

assuming all your drivers are installed to your PC, plug in the tab via the USB to your PC

run the ODIN executable

only Auto-reboot and F.reset Time should be ticked

after a minute, the ID:Com box should turn yellow -if not you may have driver issues (try this driver http://drivers.softpedia.com/progDo...SB-Driver-for-Windows-x86-Download-96692.html)

7) tick PDA and click the PDA button and navigate to the KME Odin folder and select "P7510XABKME_P7510UEKME_HOME.tar"

8) select the PIT button and navigate to the KME Odin folder and select the "android_fastboot_emmc_full_p4_16G_32G.pit"

9) Select START

it should start writing the image to your tab and once done, should reboot you back into stock

in case you want to go ahead and flash 3.2 -

use this pit file - http://xdaforums.com/attachment.php?attachmentid=784889&d=1321486916

and use this for the PDA http://hotfile.com/dl/135008863/06c...EKMM_P7510XABKMM_P7510UEKMM.rar.html?expire=1

if it asks you for Password for the 3,2 file use : sampro.pl

when resorting to odin and first booting up, you might get asked for a password, the way around this is to

a) power off,

b) press power n volume down until you get 2 icons left is recovery right is download.

c) press volume down to select recovery icon then volume up to lock it, you should then see the recovery menu

d) then use volume buttons until wipe data/factory reset is highlighted press power to do it

e)after its done wiping, select reboot n you should be ready

Now the key thing here is installing the right drivers - after installing teh driver, connect the tab and see if the drivers are installed - go to your pc control panel and check if you get a triangle with an exclamation point. If there is, right click on it and select update driver, then manually choose device - navigate through and find the Android or samsung device (cant remember the name off the top of my head)

if you get stuck, report on which part you got stuck on - currently it seems like you're mixing and matching different steps so it is a little confusing
