    Where did you find this information? If the mod worked for one person, it will work for others as well.

    Right thanks for that unfortunately "Lenovo 2.1 SLIC + WLAN WLIST check patched" bricked the machine, but the other whitelist removal one worked fine.

    We cannot know for sure. In this thread on bios-mods, at least two people provided mods and they made many attempts reaching the disabled wlist. So there were a lot of mods, and thats why feedbacks are different.

    I was able to break the whitelist check by installing a new BIOS that I modified with Andy's Tool. It was crude and I don't fully understand how I did it, but it worked better than using Camiloml's method which shows an error like I showed in the screenshot (that was someone else's screenshot but I get the same error).

    I have a 7265AC working currently, and am going to try a 8265AC and Realtek RTL8821 in the future (just for to compare BT and wireless performance). So far, the 7265AC is working very well, it's just that my router's wifi is a bit weak and Intel wireless chips seem to suffer from this (with my router). There is inconsistent performance in terms of latency and bandwidth. I have less problems with Realtek (so far) where it seems more stable and consistent. If I put the laptop close to the router it gets full performance, but it's hard to upgrade the router because the ISP forces us to use this one or VOIP won't work. It works ok, I'm just trying to learn so that I can give all of my PC's full wireless performance.

    I'm very new to all of this, I just did some experimenting. My changes broke the checksum/hash check and it won't let me install it in Windows with InsydeFlash. It gives an error and says that this BIOS isn't for my laptop. The only thing I changed in the BIOS was {E62F9F2F-4895-4AB5-8F1A-399D0D9C6B90} (WirelessDetection) where I changed from hex ID's with Notepad++. And then imported/replaced the .mod file.

    I got around the checksum check by installing the BIOS via the recovery method. Holding Windows key + B and renaming it to 1484.bin. It installs fine and I've had 0 problems going back and forth between the original BIOS and this new one. Everything works well. I can PM for more specifics of what I changed if you are curious. I have a .mod file, and a text file with the hexedits that I made. Because my method might have been luck or a fluke. I don't know if it's the hexedits for the id's that I changed or if it's because I removed the whole whitelist by luck. I only half tested it because I was just happy that it worked, and that this older laptop now has 4.2 Bluetooth and 5G Wifi. It doesn't show any error message it loads straight into Windows without any message, the same way the original Wifi card did.

    The only thing I'm curious about now is if the advanced menu can be unlocked because I'd really like to change RAM voltage to 1.35V for DDR3L memory. Is this possible? I'd also like to access CPU fan curves or other things like this. But I know so little about these advanced BIOS options I have no idea if it's even possible, or how to access them. Otherwise the laptop is working really well and has no problems. If you could help me with this, I'd really appreciate it.
