So I ran into an interesting problem...

I did the bios flash on my Y500 and everything went fine. When the flash was complete, I noticed that my laptop was unplugged and plugged it in. When I did, the screen got sort of "tinted" to a blue-ish color. I rebooted the laptop and this blue tint persists on the screen. I have tried re-installing Nvidia display drivers and rolled back my bios to v2.04 again with no luck.

After this, I also can't adjust the screen brightness with the Fn-keys.

 

Any ideas? 

I managed to resolve this issue by replacing the screen ribbon cable. Bought one from eBay for like 10 bucks and it did the trick, screen looks normal now. Super happy to not have to replace the entire screen!

I installed an Intel 7260 I bought some months ago, naively thinking I can just install it. 

I did the same, got the AC version from Amazon. Just put it in and Windows recognized it straight away and installed the drivers for it automatically.

Alright, finally managed to get it done, everything worked beautifully. The only problem I encountered was with creating the bootable DOS drive as instructed here, encountered some "write protect" error, maybe some compatibility issues with Win 10. Did manage to make a FreeDOS drive with Rufus and flash successfully.

 

Thanks to all involved!

Glad to hear it! I also ran into that write protection issue, used diskpart to remove the "read only" disk attributes of my USB drive.

What Wifi-adapter are you upgrading to?

Looks like v2.04 is still available on Lenovo's website here:

https://support.lenovo.com/gb/en/downloads/ds101628-bios-update-for-windows-8-64-bit-ideapad-y400-y500

 

Unfortunately it looks like it is only possible to install via windows, to answer my own (2nd) question.

Aah bummer. Maybe you could install Windows as a secondary OS?

Coming to this party extremely late, I have two questions:

1. Are these files still available at all, i.e. will I be able to download without issue them if I pay for the Tier I Elite membership?

2. Is it possible to perform this unlock without windows installed on my machine? Am I correct in understanding that the bios can be backed up and flashed from a bootable removable drive with DOS , and that windows is only required to do the patching, something I presume can be done with a Virtual Machine?

 

If you are on bios v1.5 and need to update to v2.04, you need to find that somewhere else. Can't remember where I got it but you'll find it with some googling.

Hello,

I can't access the files since I have a new account. Need to update my bios before doing the flash because I'm currently on version 1.5. Could anyone PM me a link to the bios update included in OP's post? Thanks.
