ASUS N56JR bricked after I added a boot option on the BIOS, I tried everything

I've read many users in other posts with a similar problem, changed a setting on the BIOS and the laptop dies.

I had 2 hard drives. One with Windows, and other with 2 partitions: data and secondaryOS. On the secondaryOS partition I installed a Linux distro, which, used an EFI boot loader. Anyway, when I rebooted the Linux distro wasn't detected so I went to the boot options and added the Linux .efi boot manually. I restared and the setting wasn't saved, so I added it again. Then I restarted and the laptop didn't turn on.

The behavior is exactly like this video of an N56VJ https://www.youtube.com/watch?v=AChVt0He-5Q

The laptop stays on, and after a while the fans turn on, probably because it heats up.

Things I tried:

- Blind BIOS settings reset
- Connecting to an external monitor
- Flashing the BIOS with the Ctrl+Home thing. I tried with multiple names (AMIBOOT.ROM N56JREH.202 N56JREH.BIN N56JREH71.202 N56JREH71.BIN N56JRHAS.202 N56JRHAS.BIN). I didn't have a 1GB flash drive, smallest was 8GB, and I had it formatted to FAT32. Should I try with 1GB and on FAT?
- Hitting my head against the wall
- Smashing all F<X> buttons after turning it on
- Disassembling the laptop and remove the CMOS battery for a few minutes
- Pressing the power button for a few minutes
- Yelling at the laptop

It baffles my mind that changing a BIOS settings can brick the laptop. This is insane. I'm never buying ASUS again.

Any other ideas? The laptop is under guarantee (it's 1 year I think), I brought it on February, but they won't take it in my country because I brought it in the US.

I friend suggested me that I could replace the BIOS chip. But it's probably soldered.

 

Removing the battery these days will only probably reset the clock: Nonvolatile BIOS memory - Wikipedia, the free encyclopedia
They use flash/EEPROM these days for the settings, soldered most likely.

As for warranty, you may find the information here helpful: ASUS Worldwide Warranty - Asus - Notebooks
Do you still have the things you bought with the laptop? From what I know, there is a yellow card in the package telling you about the places you can go to for the global warranty. Try contacting the nearest one to minimize shipping costs. If you are lost, contact Asus global support on the internet/phone and ask for help.

Don't give up on your warrantly until you have checked everything. I'm not sure, but I think if a support center is not on that yellow card, they can refuse to fix machines not bought in their country/from them. If you have completely lost hope, find someone who you can pay to fix the thing. They should be certified to fix it, again, contact Asus to be sure. Be prepare though, either under warranty or not, they may probably just swap the mobo.

UEFI support is in a sad state. There have been reports of Samsung and Lenovo (Thinkpads no less!) laptops getting bricked just by installing Linux It's very disheartening, one wrong turn and you have an issue only fixed by hardware modifications...

They should start making Dual-Bios/Dual-UEFI laptops...

 

Sounds like an asus, no doubt about that..

Have you tried hitting esc on the pre-boot? And if you can get into the bios again, disabling fast-boot seems like a good idea.. ..or at least do that next time. I think there is a weird "recovery" routine that's launched from the windows boot on the embedded ssd that sc** things up if the paths are not the expected ones at startup. Seen that happen before, but not entirely sure about the mechanics of it..

 

I left the CMOS battery out for 24 hours. Still no luck. I tried more BIOS names for the flash drive, still nothing. After initializing with Ctrl+Home it should display something on the screen if it worked right?

I'm thinking about sending the machine to get the BIOS chip rewritten, there is a computer repair shop near me that can do that fairly cheaply, does anyone knows about this? Could this solve the problem?
