LG K10 MT6753 boot partition deleted

I have a little issue with my LG K10 K430. I was experimenting with it, to learn the adb function. Well, I stupidly erase the whole boot partition using rm and then… My phone is not booting anymore. It is showing the LG boot logo, but is not starting up, keeps rebooting. I tried to repair it through LG Bridge, to flash the stock ROM through LG UP and LG Flash Tool… but my phone is not staying in flash mode or download mode, cant boot into Fastboot. The only thing that apparently works is the Factory Reset mode, but only shows the interface… it only reboots the phone and nothing else. I tried to flash the boot image through SP Flash Tool but has no luck, phone is detected by Windows but only for 3 seconds, then it disconnects. No matter what I do, when I connect the phone to my PC, it quickly disconnects, even with Driver Enforcement deactivated. I tried LG drivers and some other drivers for Mediatek, but still have no luck.

Does anyone of you have any other way to recover the boot partition data or to unbrick my phone?

I hope you can help me.

Thanks in advance.
