Thanks Serg008 for modded BIOS file. I extracted it and run winuptp.exe with administrator right on T520 running Windows 10 64 bit. A message "BIOS image file is same as BIOS ROM. An update is not necessary at this time" appeared on the screen. Can you please advise what l need to do next?
Hello!, I have a Lenovo T440 with the BIOS 2.49. I'm going to replace the Intel AC7260 with the AX200. Since I'm using W10, Bluetooth became very unstable (it randomly switches off, from time to time). I've been reading a lot, several cups of coffe... but "phnxdeco" doesn`t recognize ROM file, it feels like a puzzle (I've used Universal BIOS... seems not to be the right tool). Thankfully I found this forum still alive at the present. I couldn't find "BACKUP_Tools19". May you help me?
