Hello, The last time I want to install the infotaiment update version 1969. During the update, I got a checksum error message. How can I get out of this menu (update menu), because even resetting the tablet doesn't help.  (picture below). The Resume button is inactive, but nothing happens when you press the retry button. Thanks for your help.

Hi,

 

Can you shutdown the car, lock it to force to power off infotaiment? 

 

What was your idea to gain with new update....the guys who update say that they dont see any difference or new stuff... 
Checksum error means that there is problem with data that its been read from file, so problem can be downloaded file itself, usb drive, bad block on drive.
First check file, clean download new, unpack as it needs to be, and be sure that you have decent usb c drive, not some cheap device. 
If you you use adapter from usb a to usb c it can also be a issue with that...

What version was previously installed on infotaiment that worked normal?
On your place i would restore to old working version...if this works fine...great, because you have restored functionality of your mmi.
Possible you need to upgrade version by version on steps,1-2-3, not from 1 to 3...

Mind that not all infotaiment are the same, so be very sure that new update will work on your device hardware.
(because it would come OTA by default for your car) 
 

i have on octy IV 2023  sw version 1941 and still thinking about wait a little bit to see if the 1969 is issue proof or nest of new bugs...
 

hello, thanks for your reply.

 

I had the 1941 version. I just wanted a newer version. When I reset the tablet, it comes back all the time to the updates menu (photo in the first topic). On the other hand, when I click on retry (resume is blacked out), another screen appears and nothing happens (a picture in attachment). The flash drive is new with USB-C. So far I've turned off the car, the infotainment system (tablet) also turned off but I couldn't close the keyless (with my finger). Tomorrow I will continue to deal with the matter. Do you know how  I can exit the update menu ? or continue updates ? thanks for your help.

I guess that you have tried to press Power button for more than 10 sec...
I dont know did the new sw installed correctly, let say it did, but as you get NOK status, if its applied new files over old files but they did not match...maybe the infotaiment is on some half floating mode,
where it cant boot properly, or it cant because the files from update are not matching file system or cant be read, or corrupted....

Hope that 10sec on power button makes some reboot to working mode. 

Did you try to plug usb back to pc is it readable and do list of files and folders look as before you update the car

10 sec on power button didn't help. USB is readable and do list of files and folders. I cannot exit update menu i after restart or shutdown the car is still on.

Sorry to hear that info….

 

Maybe someone from this forum with more knowledge will answer you, but in general we can see that update did not pass well or at all.

 

Maybe try to put 1941 on usb and restore if it will accept restore.

 

Or drive the car to dealer, so they could reprogram mmi with oem tools.

Maybe say to them that OTA did not pass, to try to avoid expense….decide yourself.

Curious to hear wether and//or how you have resolved this.

One thought was to redownload the update, put it on the USB stick, and see if you can initiate the update cycle again.  A checksum error could indicate that one of the downloaded files got corrupted and when the system does a comparison of the file to the hexadecimal checksum it can see there is an issue?
