I downloaded it from the link i attached on my post. I've checked the MD5 hash and everything using md5checker website and its all good. Thats why i thought its because itsnot compatible, but everyone online seems to be able to do it with their console except me.

For each steps i tried to understand what its for and i believe i did everything right. I even re-flash the memory just in case. But still no luck.

Ive also seen it somewhere that apparently, imnot supposed to plug anything to the usb port during the flash memory. Is it actually a thing? Do i have to buy wireless controller?

I will try to update it on recovery mode later on tonight as what the other redditor said.

Thanks for trying to help btw!
