Blue screen appears, after that my device no longer works, on Blue screen qr note it shows some text about bios, so I think my device bios was cropped, so at this point I badly needed your help.

Well, at that point it could be a hardware issue caused by corrupted BIOS but to be sure try:

  • reflashing your bios again since even a smallest nudge can ruin the flash.
  • make sure all cables are well seated in the laptop. As you get no display make sure eDP cable is well connected to the motherboard and then try turning it on
  • try booting without the SSD/HDD if possible and see if you get anything on screen
  • try booting with disconnected battery
  • if the device has NVME slot there are NVME PC diagnosing tools on Aliexpress you can maybe use to get a error code, but there is no guarantee
  • reconnect the laptop as it was before and leave it to charge overnight and try booting it in the morning

If nothing helped you could try everything again with full battery, but at tthat point it’s probably a hardware issue that requiers special tool and lots of skill and money to be repaired and it ould just be cheaper to buy a new one.

*All of the steps listed are general and since I don’t know what does your laptop look like inside some steps might not be possible to execute.

At this point i suggest you to take it to a repair shop.

Yeah, if you tried everything I listed, I really can’t help more than this. You could try it again and *maybe by some mirracle :sparkles: it starts working, but I’d just suggest returning it or handing it in for repair if you don’t know how to microsolder.
