I've managed to roll back to  stock DXJK2 (from Overcome GB v3 c/w latest kernel and ext4)and flashed stock GB  ,DXJPD with Kies.
Here's what i did:

a)Flash with Odin3 v1.7
1. Download P1000DXKM3 from here. P1000DXKM3  -  http://www.4shared.com/file/pqPvd29x/P1000DXKM3.html?
1. Backup your data.
2. Extract the firmware files from the P1000DXKM3.7z file.
3. select P1_add_hidden.pit for .pit file.
4. check repartition.
5. select AP_P1000DXKM3-REV03-ALL-CL874291.tar.md5 for PDA.
6. select CP_MODEM_P1000DXKM1_REV_00_CL873880.tar.md5 for PHONE.
7. select CSC_P1000OLBKM2-MULTI-CL878295.tar.md5 for CSC.
8. Flash your tab and wait for it to restart.
9. Welcome back to stock.

extra steps
10. Root by using SuperOneClick v1.9.5 by CLShortFuse.
11. Unsign Bootloaders by using this SGT-Bootloader-Patch by chainfire and rotohammer.

b) Go to Phone on tab, key in code :  *#272*your device IMEI#
Change CSE code from KOR (korea) to XME (M'sia). The Tab will reboot into recovery then auto reboot into the default start menu/set up
c) Now flash DXJK2 using Odin. Rom here:http://www.4shared.com/file/-87CbOF3/P1000DXJK2.html?
Use pit and put the entire tar file into PDA.
d) Connect to Kies, now rom detected as CSC - XME and xme gingerbread offered as update. Well. you know the rest.
As for rooting, I used Chainfire CF Root.

The solutionis  on the 1st page of this thread.Anyway,if you haven't got it already,switch off tab by pressinng and holding power button. Press and hold volume down and power button until you see samsung logo. You are niw in download mode even thiugh you have the same pc logo. Reflash with odin km2
Dxkm2 has signed bootloaders which is why yiu have to root and install bootloader patch app and run it to make your tab safe to flash jk2.
What to do. We learn s we go.The other thing-dont do this kind of thing late at night since tired and can't think straight. Also no one can help since all asleep.

Think the improvement is in the browsing experience -it's smoother and faster. Also flash is better.Scrolling in ui is smoother.As for the hardware,with the specs the tab has,,it should run anything. It's always about marketing- getting consumers to buy new phones/tablets.

I've try *#272* and IMEI but still nothing happen still not Malaysian XME what should i do.

Thanks I got it already. Plug in to Kies still Korean Tab.

I think I've to flash the P1000DXJK2.

Same as you stuck in the handphone and computer exclamation logo can't go to download mode am i bricked my TAB?

What does kies say about  your pda and csc ?when you key code *#1234# what do you get for pda/modem/csc.

It is difficult to help when there i s no background info.most of the time the result is stated and not much else.

@kokifung:looks like you are still in romania. Use the code to change csc again and if menu allows you to change to xme.install and your phone will hard reset.if it boots into pc screen, flash again.

I've successfully complete the first part.

My Tab stuck at the computer & handphone exclamation mark, can't go to download mode.

At download mode how to flash rom?

Do I need bootloader patch before DXJK2.

Also do I need to check partition? 

Thanks

There are only 3 of us left on this thread. LOL.I really regret sharing what I did to get back to stock xme.
For the last time:
@kokifung: flash back to dxkm3 and connect to kies to try to update.
@jhonsonlee: flash back to dxkm3 to revive your tab.

flashing into dxkm3, then ??

do i need to change the code?
need to root before update in kies? 

edits: had complete flashing into dxkm3,
in kies also failed to update..
now my tab version is
pda DXKM3,
phone DXKM1,
CSC: LBKM2...

Okay, I compiled some pictures and instructions on updating via Kies here: http://ihearthese.blogspot.com/2011/06/upd...axy-tab-to.html

Along the way I noticed there's an update for Kies: v2.0.1.11053_99
still downloading now

Can't you use ODIN to update your tab using the latest update GB for SGT? maybe KIES is having problems updating your tab... Heck, even KIES doesn't load properly on my PC W7x64....

The reason why some of us want to try to rollsback to stock is because of current hardware issues or  in the event of future issues , go to samsung malaysia and claim warranty. Of course if full hard brick then obviously can't roll back.
I think this situation applies to jhonsonlee since his tab has LCD screen issues.

As for kokifung, he hasn't got samsung malaysia warranty since he has AP set. So, no one knows why he must malaysianise his tab.

After flash the DXJK2 do the *#272*IMEI# then plug to Kies you should able the XME Gingetbread.

Added on June 30, 2011, 2:16 pmAfter flash the JK2 do the *#272*IMEI# install XME

then plug to Kies the new update will pop up for you to update the XME Gingetbread.

Good luck

I need to use Kies because my Tab LCD flickering problem that's why I need it to flash back to XME.

Now I've successfully back to square one M'sia Xme Gingerbread.

Is the P1000DXJPC M'sia XME.

PDA: P1000DXJPD

Phone: P1000DXJPD

CSC: P1000OLBJPD

Happy for you guys. Went back to modded rom after two days.Now on dip7's jpd rom and koxudaci's kernel. Problem with samsung keyboard on lowyat seems resolved. Now cursor back to normal.
For me with stock jpd, the temp quite high but now ok.
