Re: DO NOT UPDATE BIOS 4KCN43WW ON LEGION Y520

Sorry bro I'm afraid I do not have a fix for that. Try searching in other website.  Doesn't have to be a Lenovo where you can always search for other laptop brands that are having the same problem after some updates.

The solution is directly above your post. Go and check it out. I even attached a picture of the interface once you pushed F2 directly after the legion logo. Goodluck

Re: DO NOT UPDATE BIOS 4KCN43WW ON LEGION Y520

The version 4KCN30WW download is not working for me. There is a 404 server not found error. Is there anything i can do to get this version? This the one I need.

 

Thanks

The current one is  5XCN24WW 13 Aug 2018 and is giving me an urgent to upgrade.

Last time I installed an "urgent" BIOS update from Lenovo, I ended up having to completely reinstall the OS from USB after finding no way to boot the computer for a week. I'll never make the mistake of quickly installing a BIOS update again.

Was wondering that, too. I've postponed installing it...

Re: DO NOT UPDATE BIOS 4KCN43WW ON LEGION Y520

Probably the way to go. Ever since I started building my PCs, around 1996, I've never missed a BIOS update. It's the first time I've seen a company screw up this way...
