2017 TFT R1200GS.
With genuine ICOM using ISTA
We have updated the software from K001-23--03-501 to K001-23-07-531.
There were updates for BCO and KOMBI.
The update completed without any problems, but
Then I did FDL coding
Diagnosis in ISTA after coding is error-free.
I disconnected the ICOM and cleaned it up.

When you turn the bike back on,
TFT meter suddenly restarts.
Then turn the switch off and on again,
The TFT meter remained dark and did not display.

I panicked.
Fortunately, a TFT meter was displayed when connecting ICOM.
There are many fault codes when connected to ISTA.

I rewritten ISTEP to 22-11-501 in ESYS 
I changed it back to 23--03-501 using ISTA again. No problem.
(currently no coding)

My friend's R1250GS also had a recall update done at a BMW dealer in July. After that, I asked a friend to do the FDL coding for me, but he told me that there were problems such as the TFT screen restarting or not starting up.

I think there is a problem with July's ISTEP (K001-23-07-531). I think.

Has anyone had a similar experience?
Please let me know if you have any information
