Tanks for your fast response. I've tried to hold the power button for 10 seconds, but that wasn't successfull.

You tried to charge the tablet and then turn it on?

[Milkquarious]

Yes, i charged it the whole night. Had the same idea

[hocuspocus69]

Have you seen the battery logo during charge?

[Milkquarious]

Sadly no. I didn't see anything. The display stays black and without backlight.

What you device serial number ?

[Milkquarious]

Serial-No.: T9GT32GB15421780751

That's the only Number i found on the Tablet.

Try to flash this preloader again, only preloader. if the flashing process works now, but the display not working, maybe you have a problem with display.
Maybe It was disconnected from a socket. Check it.

I've tried that but also without success. I don't think that the hardware is defective because it worked before i flashed it to a brick. I've also tried to use "Firmware Upgrade" and "Format All + Download"

this preloader from tablet T9GT32GB154XXXXXXXX series. Its differs from stock and only it is suitable for your tablet series, but also suitable for other. Try to download it and flash stock rom with it now. Maybe it was damaged. if the flashing process works now, your tablet must work. Or you have hardware problem, or do something wrong. If you can make a video of flashing process.

I was in the same situation some time ago.
SPFlash tool will detect tablet when is connected to PC? Look in Device Manager (tablet must be powered off... I think already is, but not forever ).
If is detected you can try to keep power +volume up(or volume down) pressed for over 30 seconds before you connect to an previously used USB port.
SPFlash Tool must be prepared, with firmware loaded and download button already pressed.
If not detected, you can try with another USB cable (a good quality one). I think it was a mistake when you used Format All + Download.
If that command worked, you successfully erased your IMEI. Without a TWRP backup will be pretty hard to rewrite your IMEI. Good luck.

I had some sparetimie now and tried your solution, but the tablet didn't come back to life. The flashing process finishes without any error.

I recently tried a 128GB micro sd card in the T9 and it worked without any problems.

The card came formatted with FAT 32.

What would be the most reliable way of over coming the 4GB file size limit?

I do not know what file systems will work with the T9. Although I do know that NTFS is not one of them!
