Hello,
I had problems with my old wireless card, keep disconecting from the wifi. I bought the intel 7260HMW (dual band AC) and I still get the message from the bios.
I have the lenovo m5400 with bios 1.02.
Can you help?
Thank you
Hello,
Please remove the whitelist for this model (Lenovo M5400 20281) and add any available advanced options:
- BIOS download (J6ET58WW - 2.03): https://download.lenovo.com/ibmdl/pub/pc...et58ww.exe that can be found here if the direct link doesn't work.
- Original WLAN card: Broadcom BCM943142HM
- Replacement WLAN card: Intel 7260HMW (Intel Dual Band Wireless-AC 7260)
Thanks in advance!

Hi
Your bios is rewrite protected
you need SPI-programmer+SOIC8 clip
I have no means of obtaining those for at least another month which is way too late for this project, I've seen I can disable the rollback protection in the BIOS itself, doesn't that help with flashing?

Ok, I'll get the required tools, do as instructed and come back.

First you need to make a dump using the SPI-programmer
