[Galaxy Tab Q&A, Help & Troubleshooting] schyzo001:
Thank you very much for trying helping me.

But as I said, I can't access to any mode with the tablet : nor download or recovery mods.

I made the hardware modification, but I'm not even sure my welding is good...

So the only way to access download mod for me is to follow the steps in this thread : http://xdaforums.com/showthread.php?t=1312391

I followed every steps.

Here is the log of Ultimate UnBrickable Resurrector :

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

1. Apply UnBrickable Mod

2. Remove then insert Device battery

3. Connect to computer via USB.

4. Click the Download Mode button

5. Download new software with Heimdall.

So, the device turns on, the flash light turns on too, and as the log shows, it seems to be in download mode.

Next to that, I ran the Heimdall One-Click to flash firmware and here is the log :

As you can see, the P1000 is detected as a S5PC110 (Galaxy S)

But as said in this post : http://xdaforums.com/showpost.php?p=24341888&postcount=95

I think it should be detected as S5PC111 and it's not my case...

The Heimdall One-Click uploads some things to my device, and when coming to FACTORY FS, it justs stops at 32%.

As it's said in the related post, I made it a second time checking the Flash Bootloader.

It starts to upload PIT and stop immediately.

So...I really don't know what to do next :(

I'll paste the same post on the other thread, just in case...
