Tablet does not turn on after modding it.

[cat 06]

Hi everyone, I have a sm-t580 tablet on which I installed twrp and a custom rom, recently I restarted the tablet in twrp and I cleaned all the partitions, I did this by mistakenly restarting the tablet in the operating system via twrp even if there is no there was no rom installed. Once this was done, the tablet restarted in download mode (fastboot), it was a bit in download mode and at that moment I was not there when I returned the tablet had turned off because it had downloaded.
I put the tablet in charge and now I can no longer turn it on even in download mode (fastboot) the screen turns on only when it is charging but in any case I cannot start it in any way in any mode.
Anyone know how I can fix it? Thank you very much who will answer me.

If you cant get back into download mode , you must of damaged it somehow by wrong twrp or something you did .

I managed to start it in download mode for a short time, I didn't have time to flash anything and the tablet turned off immediately after.
Maybe it has such a low battery that it cannot start, but since there is no ROM installed it does not even charge.
What can I do?

Yes, it was the cable that did not allow the tablet to charge, once I changed the cable I managed to access the download mode.
