[Tool] Lenovo (H2O) Bios Unlocker and Locker

Yeah just join that server and you’ll find solution I’m certain

I actually did, they are clueless on the problem.

So why is there no solution to this? Garbage laptop as I understand?

What is your BIOS version?

Switching pc-state from 2900mhz to 3000mhz happened on fscn20ww.

Download fscn20ww, extract the bios.fd from it, rename it to FSCN.bin, place it on an empty FAT32 formatted flashdrive. Name the flash drive FSCN as well. Unplug everything, hold power key to make sure laptop is off. Hold Fn+R, then press the power button, while keep holding the Fn+R until it beeps

The problem is that this crisis mode doesn’t work. I had a second functional legion with the same parameters, i.e. (r7 4800h rtx2060 144hz) on which there was nothing combined and there it was that you had to connect the power supply first and then press fn + R and then press the power button, i.e. a little different order than here on the forum. The crisis mode itself was also activated without a flash drive. So that I’m not mistaken - Yes, there was a sound signal, this is how the orange power LED on the back of the laptop flashed. There was a newer version of the fscn26ww bios on that one. But as I wrote on my legion, unfortunately, the chapel - neither the order nor the forum, nothing reacts to it.

You’ll need CH341A to reflash the bios then

I gave it to the site a week ago for bios programming. He programmed something, but whether he gave a good bios input to this model, etc. I do not know. He suggested that you could try to program kbc but he has a problem with finding the right batch for this model. He gave the equipment back. What do you think? The laptop itself came back from the service and behaves the same. You can see traces of flux on the bios chip, so he must have been doing something. And the question is, did changing pcstate-0 from 2900mhz to 3000mhz physically damage the processor? Because if so, you probably have to give up this laptop and look for another one. What do you think?

Legion 5 Pro 16ARH7H Laptop (AMD CPU)

Firmware: JUCN58WW

Please help unlocking advanced menu by confirming " Legion_2022_Insyde_BiosUnlock.cfg" works with above configuration.

Hello

I’m facing a really weird issue with my Legion 5 15ACH6H - Type 82JU (RTX 3060, R5 5600H). I have tried everything and this is really my last resort. The post is a bit lengthy, but please bear with me.

I bought a Samsung RAM kit 2x16 that is dual rank x8 1.2V, installed it into my laptop and it booted fine, Windows is working fine when doing normal tasks, but once I launch a game, the laptop either completely freezes, the game crashes or I get a blue screen. With every single game. Initial reaction was “well ok, the RAM must be corrupted”, I do a memtest and indeed I start getting errors. But then, I get this another idea to try this RAM on another laptop I have (HP laptop). I put it there, it boots fine and everything and doesn’t crash when launching a game. I tried multiple games, benchmarks and stress tests, even memtest. No errors or crashes whatsoever.

Back to my Legion 5, the RAM just doesn’t want to work, it’s not like I can even play for a few minutes, it crashes at the very beginning of a game (during the splash screens).The previous RAM I had in it works just fine. I cleaned drivers and installed them again, even did a complete format, but nothing helped.

So I thought maybe there’s something in the bios fucking up with the new RAM, so I came here and downgraded my bios to a compatible one with this bios unlocker, and started fiddling with the advanced settings, especially the RAM and CPU voltage/clocks, but I honestly had no idea what I was doing, just putting things in randomly and seeing if it works, but nothing helped. Bricked the laptop a few times but thankfully I was able to reset it by removing the CMOS battery (complete lifesaver btw).

Now I’m hoping someone here has an idea about what’s going on with this RAM. Have any of you encountered this problem before? Do you have any suggestions as to what I should be changing in advanced bios to make this RAM work? I would appreciate any help or suggestions.

I also noticed something when comparing CPU-Z information of the same RAM on the two laptops, and I noticed a few differences in like FSB:DRAM and tRC numbers…etc, and the numbers on the HP laptop keep dynamically changing on the HP laptop depending on the activity, while on the Legion 5 they are constant no matter what I do. I don’t know if that’s relevant or not but here are some screenshots: Imgur: The magic of the Internet

This is the RAM btw: https://semiconductor.samsung.com/dram/module/sodimm/m471a2k43eb1-cwe/

Thank you very much!

Try EC reset. Unplug charger, hold power button for 60 seconds (even when the laptop powers on, hold it down)

I have the exact same laptop with the same BIOS version. Could you instruct me on how to unlock my BIOS? I flashed smartphones before, but firmware stuff still makes my brain numb. I don’t know if I should run EFI or EXE, and what config to use. It doesn’t help that the thread spans several years and unlocker versions. If there’s a definitive instruction on how to do this, I should be able to follow it. I’ve been looking for a way to unlock my BIOS for a long time now.

If you have GNU-based distro installed only and there’s no capability to run Windows executables, you choice is the EFI unlocker.
There’s no other significant dependancies to use EFI rather than EXE, except your BIOS version, because the backdoor was fixed later.

I tried running the EXE as admin, but all I get is this:

Unlocking
Incorrect function.

Press any key to continue . . .

I don’t know why. It worth trying the EFI.

Should I write the “Legion Unlocker” image to my USB card and then boot from it? Is it suitable to our Ideapad Gaming 3 BIOS?

Yes. This is what the image is meant for. It is just a set of files I packed into one for the sake of convenience.

Both EXE and EFI are unified for the same list of devices.

Thank you, it worked smoothly. I have access to advanced settings now. I was too anxious to mess with my BIOS without guidance. Do you know how to disable SMT (simultaneous multithreading), by chance? I couldn’t find any clear setting for it. I’m in dire need of increased single core performance. I would send you a direct message, but my account level isn’t high enough.

SMT is implemented in Intel processors as “Hyper-Threading” technology, isn’t it? What is it called for AMD? As simple as AMD SMT? I would check if there is any option to disable SMT, but I’m in no position to deal with such sophisticated queries ATM.
