Trusted Platform Module 2.0: Error Code 10 after Downgrading BIOS

Hi there peeps!

I'm writing this lines in hopes for finding a solution to this unusual problem, I have been looking on Google, but none of the solutions have helped me...

The Story:
This is an Acer E5-553-1786 Laptop, and I decided to upgrade to Bios 1.31 in hopes of getting rid of my spontaneous reboots (WHEA 20 Error with Hyper Transport), and also, because I felt Spectre (Or Meltdown) patch was included in it.

Sadly, I found that the damn thing just made the sudden reboots worse than before, getting a reboot once every 2 days, instead of once every month... So, my only solution was to downgrade the BIOS to see if I regain "system stability" (Man, this laptop sucks, I even have to hax the BIOS to enable virtualization... don't ever buy an Acer...)

Now, after downgrading, TPM 2.0 now shows a yellow sign,a nd a code 10, saying the resource is already in use.

What I tried so far:
- Restoring to a previous image of windows 10: Nothing changes
- Trying to update the driver: Says has the most suitable version
- Ran troubleshooter: Did nothing.
- Restoring factory defaults on BIOS: Nada...
- Downgrading to another version, and then re-flasing the version that works (In my case 1.19): Nothing
- Using a previous dump of settings I had with an utility called H2OUVE, and hopping for the best: Nothing
- Clearing CMOS completely: Nothing

I'm using Windows 10 Build 1703, as I'm waiting for 1803 to become stable enough to be usable. Latest drivers available for everything.

I don't know if I did something incorrectly that might caused this, or I'm doing it wrong that I can't be able to restore this thing. Upgrading again is not an option for this BIOS since has tons of problems (Unless they release a new version... *sigh*)

I attach pictures of device manager and the pin I used to clear CMOS in this particular model.



Any suggestions?

Thanks in advance

Cya!

 

Thanks for your reply!

I have tried uninstalling the device and manually reinstalling, but seems there is only one driver, and does this, tried scanning for the driver, but just installs the same it has currently, looking for it on Windows Update results in saying it has the best driver already...

The hardware ID is this one:



Thanks a bunch for the help! (Glad to see this is not my BIOS fault XD)

 

Using the tpm.msc module results in the module saying I have no TPM installed on the PC (While there is one... supposedly, at least AIDA64 says there is one module present, and it's 2.0). I tried using the Powershell command clear-tpm, same message.

Thanks for the suggestion!

 

Yes and yes, also secure boot is enabled. Legacy mode would result on a non bootable media found error.

 

Thanks for the link @Hadron-Curious ! I've tried upgrading or installing from the package (uncompressing it, due to being an HP executable) but says the best driver is already installed, forcing an install results in not being able to install the device, because the driver is not digitally signed

Any other suggestions?

I did as you suggested, obviously I had to disassemble this (which fortunately is relatively easy). But still the TPM thing shows a yellow sign.

Stupid question, has TPM something to do with a probably patched BIOS with Spectre or Meltdown remedies?

This system was built on 2016 (according to Acer dates), and I bought it on November IIRC. The Windows version I'm running is 1703, I'm waiting for 1803 to become more stable to upgrade and wait another year to do a major upgrade again.
