[Galaxy Tab 8.9 General] mobjunky:
This worked for me with similar problem

Hi Spazlon,

Sorry I'm not allowed to post links yet as I am also very fresh. But I've underlined the addresses so you should be able to find them

I just spent the best of 2 days trying to solve a similar issue - my 8.9 P7300 kept running in boot loop. It had been running ICS stable for several weeks, then suddenly started to loop boot for no good reason. Anyway - you need two programs installed on your computer as well as USB drivers for your tablet. The two programs are Odin and SDK developer package. Odin3 v 1,87 and 1.85 are found here:

filecrop.com/Odin-1.87

- try some of the links, one of them should work without having to type a password. The SDK is found here:

developer.android.com/sdk

You can find more about how to use the developer package on that site as well, but I installed as support for Android 2.1 through to 4.1

Also install the USB driver files for your tablet on your PC. For example from here:

xpdrivers.com/usb/_1_24.cfm?gclid=CL2O_oiDs7MCFWF7cAodxFYANQ

You also need the following recovery files which you can find by searching the developer forum for galaxy tab 8.9:

ClockworkMod_Recovery_v5.5.0.4.tar

P73xx_Stock_Recovery.tar

Clockwork_Recovery_6.0.0.8_GT-P7300.zip

and finally a ROM of your choice, for example the ICS rom cm-9-20121028-NIGHTLY-p5.zip that I just used. You can find the latest official ICS ROM's here

get.cm/?device=p5

Now - hold down the volume down button on one of the boot cycles. You should now get into a menu with two choices - Download and Recovery. Default is "Download" - if you press volume down you switch between the two choices. Press volume up to select the choice you want.

First you want to select the "Download" option. Then connect your tablet to your PC. The drivers should now install and your tablet should read that you are connected.

Now start Odin3. Click the PDA button and select your P73xx_Stock_Recovery.tar file. Then press Start.

Once finished the tablet will reboot, and you now need to once again get into the recovery menu. Now select the recovery option, not the download menu. You get into the stock recovery menu where you navigate with the volume buttons and select choices with the power button. Do a full factory reset and wipe the cache. WARNING - you will loose ALL your data, but it'either that or stick to a bricked tablet so.... You will also loose your root access,m which is why the next step is needed.

Now that everything is wiped clean you can use Odin again in "download mode" to install ClockworkMod_Recovery_v5.5.0.4.tar with the same procedure as before. You now have root access.

Reboot again and once again into the recovery mode (not download mode). Once you get into the CWM recovery menu you are ready for the final step, which is to install your new operating system.

Go to your SDK installation folder and find the folder named "platform-tools".

First you want to copy two files into this folder (provided you want to install Cynaogen Mod 9):

Clockwork_Recovery_6.0.0.8_GT-P7300.zip

and

Your ROM file of choice

Press shift and right-click in that folder and select "Open command window here". In the command prompt write

adb shell

Note - I had some problems here which was caused by lack of permissions. On your tablet in the CWM menu there should be a choice under the advanced menu for fixing permissions. Use that and you should be able to get into the terminal shell afterwards with the adb shell command

Now write the following command sequence:

•	mount /data (don't worry if you get an error message - it means the folder is already mounted)

•	cd /data

•	mkdir media (if you get an error message saying the folder already exists, that's also OK!)

•	exit

•	adb push Clockwork_Recovery_6.0.0.8_GT-P7300.zip /data/media

Now you may have to wait a little while until your command prompt is back confirming that the file was uploaded.

Now on your tablet go to the menu point "install zip from sdcard" and find your CWM file that you just uploaded and run that.

Reboot once again into the "recovery mode" - we are now nearly finished.

Run the above push command again from the computer terminal window, this time to upload the ROM file you want to install. (the command is adb push [filename].zip /data/media)

Now on your CWM recovery menu once again run the zip file you just uploaded from the "install zip from sdcard" menu

When completed and you now reboot you should have a completely fresh android installation. Hope this helps.

Remember to mark this thread with solved if it works!
