Upgrade Dell laptop TPM from 1.2 to 2.0

Dell TPM Upgrade

• Download the "Dell TPM 2.0 Firmware Update Utility" from the Dell support website
• Create a FreeDOS USB stick:
  • Format USB stick to FAT32
  • Mount USB stick (required by unetbootin)
  • Download unetbootin
  • Run unetbootin (as root), select FreeDOS, select the right volume, and install
• Copy the downloaded firmware update file to the USB stick
• Boot the laptop from the USB stick
• Once on the FreeDOS prompt, move to the USB stick volume by issuing C:
• Execute the firmware update file, validate when prompted, device will reboot once done
• After rebooting, the Dell logo should appear with a message saying that the TPM is being upgraded

\o/ TADAAAAAAA \o/

TPM 2.0 now works!

Will works to Dell inspiron 5547?

if the dell model is not supported in dell website, no TPM2.0 can be downloaded in step 1, which means no TPM2.0 supported or be upgraded.

Thanks for posting this!

I found for my old Dell XPS 9350 that FreeDOS 1.0 via unetbootin would not boot (blank screen with flashing cursor).

I was able to dd FreeDOS 1.3 LiteUSB img file onto a USB stick, copy the TPM 2.0 update utility to that filesystem, and then boot it to run the TPM update.

Many thanks @mdeous
Just a note, you need to use the initial version of Dell's 1.2 to 2.0 TPM update tool. Later releases don't seem to work with FreeDOS.

DellTpm2.0_Fw1.3.1.0_V1_64.exe worked for me, the most current was 'V3' and wouldn't open.

attention please
with a TPM update file downloaded from the dell site
I own a broken Dell laptop.
Even though TPM is disabled and m2 is without password, the laptop does not show signs of life after running TPM update.exe
DELL security has reached the bottom with TPM

@gitothy DellTpm2.0_Fw1.3.2.8_V1_64.exe runs in FreeDos 1.3 Lite. Currently it seems to be hanging on the actual update, but I'm not fully sure.
