Here is the zip file.

@RogueDragon - Put 6DA back to 0A - This does not appear to be correct for some reason, it should have been either 00 or 01, so do not change it.
Then test and see if you can now dump biosregnew (new name) and write it back, after having change 16 and 18 only, that may be all you need

@Lost_N_BIOS, got it.

@Lost_N_BIOS, still error 167, even after restarting laptop multiple times.

You only need to restart once Now, boot back to RU and show me top area again, and 6DA
You do have secure boot disabled, and any password or encryption disabled, correct?

Go ahead and set 6DA to 00 and see if that fixes it If not, go back in there and set 0A again

You may need flash programmer here We already tested sleep bug, correct?
If not, put system to Sleep (S3, not hibernate) for 3 minutes, then wake it up and make a new BIOS region dump with new name again, and then try to write it back.

* Edit @RogueDragon - WAIT!! I see the issue, do not do anything yet, I'm writing you out new info!

@RogueDragon -
In setup, please set 16 and 18 back to 01 and if changed, set 6DA back to 0A -

You need to make these changes in PCHSetup, not setup!
Here is the correct GUID to make the changes in >> PCHSetup >> GUID: 4570B7F1-ADE8-4943-8DC3-406472842384

While I wait, here are pics of my bios security settings.

See edit above, sorry I missed that all along!!

This is what 16-18 and 6DA are inside setup So, set these all back to how they were, or just reload optimal BIOS defaults, whatever is easier for you, then make the edits as mentioned in my edit above Then we should make progress finally!

VarStore: 0x1 << This = Setup
VarStore: 0x17 <<< This = PCHSetup, where the stuff we need to change is located in this BIOS, not usual location, so I didn't notice it until trying to figure out why we seen 0A @ 6DA

I changed setup back to default. What am I supposed to change in PCHSetup? The same variables (0016, 0017, 0018, and 06DA)?

Yes, same variables, just in PCHSetup, if any are 01, change them to 00 - So, 16, 17 and, rest (18/6DA) are already 00
Probably, really the only one you need to change is 17, this is normally what we disable, I just gave you 16 and 18 just in case, and 6DA to check because it will cause error 28 if set, once BIOS Lock is disabled (17)

Once done, reboot, make new BIOS region dump with new name, and then try to write it back, this time should = success

Still error 167. Tried sleep bug as well.

Wow! Sometimes it can only be removed by editing a BIOS module, then programming back in, so this model is one to add to that pile sadly
You need CH341A + SCOI8 test clip with cable, let me know if you need linked examples on ebay.

One last thing we can try >> CPUSetup @ GUID >> B08F97FF-E6E8-4193-A997-5E9E9B0ADB32
Set BIOS Guard 0xDB >> Set 00

@Lost_N_BIOS

Sweet! Now, send me this final biosregnew, make sure it's dumped new after you unlocked BIOS guard
Then, tonight I will have you unlocked BIOS, unless I can get it done here in next half hour.

Here you go. Thanks for all you help!

You're welcome!
I\m just glad we did not give up, or you'd have to wait weeks longer, if you even talked yourself into getting programmer setup (it's cheap, everyone should have a set!)
