Thunderbolt 3 firmware 1.1.0.0 (Rev69.4) for U729 issues

[chrisvmlabs]

The latest TB3 firmware update package 1.1.0.0 for Lifebook U Series with TB3 contains a NVM firmware revision 69.4. There must be a bug somewhere that causes DP Alt model to stop working.

The external display only works on a Thunderbolt 3 docking station after upgrade. Any USB-C docking station that uses DP Alt protocol will not give a display (tested on HP G5, G2, and several Lenovo USB-C docking stations, whcih all worked without any issue previously).
The Fujitsu official firmware package will not allow you to downgrade to package 1.0.0.0 (https://support.ts.fujitsu.com/Search/SWP1253111.asp), which contains NVM revision 60.

Currently, to roll back, I used the Lenovo N24TH13W (https://download.lenovo.com/pccbbs/mobiles/n24th13w.exe) as a donnor with the firmware binary file extracted from Fujitsu's 1.0.0.0 pacakge via command line (PowerShell):

Code: Select all

.\FwUpdateCmd.exe FWUpdate "$(.\FwUpdateCmd.exe EnumControllers)" FCCL_LIFEBOOK_U729_TR_HR_2C_C1_rev60_wo_Cypress_SEC3_sign.bin

The firmware binary can be extracted at

Code: Select all

%temp%

while running the original update exe file.

I can confirm the DP Alt function is restored after rollback. Recommend Fujitsu retract the 1.1.0.0 release.

Hello

Please, check with our system and USB Type-C port replicator. Additional to that with USB Type-C display directly connected. With Rev60 it works and With Rev69.4 no picture on external displays.

Sent the information to our lab and wait for confirmation about that. If issue is reproducible in lab too, we will open enquiry to our engineering.
