No I have not lost mine I was just trying to be helpful !!!
I do have both v6 and v6.1 and I was reading the labels on both the DVD type cases that the sd cards come in and the cards themselves.
In spite of my thinking that I had cleared the SVM error I have not managed yet !!
There was never a 0910 released on the six monthly upgrades as supported by this link, page 1 under spoiler - shows historic files.

0915 was was the 2018 release for June 2017
0810 was the November 2016 available in December for 2017/2018
I suspect 0910 that you have was an incremental release outside of the six month release, may be why they called 0915 v6.1 ?. Seat have done something a bit similar not releasing the High 177 latest one, but a quarter before which nobody else has released, not on the six monthly cycle. That means anyone who gets excited to try to update the maps themselves on a high via the back end menu wont have a restore copy once Seat take that release off their servers. They would have to go to 175 if they don't who have Mapcare or retrofit software.
The OP has not come back so they have either lost interest or didn't bother to say thank you that it worked. SVM errors can be tricky since as I mentioned before they can go down several levels requiring a repeat clear, reboot and the code to clear check again since sometimes that changes. Originally thought to be static but no they change least on the MIB2 High with retrofit firmware.
I seem to get an SVM with my retrofit firmware after the June update or radio icons I updated... not so sure where it came from. Clear code changed, recomputed it and it fixed it
. Saying this I did get an error saying navigation data was not valid recently on the FIS screen and a VCDS error of the same. Reboot fixed that. Cleared that if not twice on
OBDELEVEN, clear errors and it went away since. Not an SVM error thou. Think these were related possibly to the retrofit firmware or may be the unit didn't boot up correctly on a one off start up. Bag of cat litter in the boot at Pets at Home and it blew a raspberry. Wait to see what the next release brings. I share notes with Walone on any idiosyncratic behaviour of the retrofit software on the High.
PS if it really is 0910 their solution is to buy that card again off ebay and just copy the overall.nds file out if they can't get it from anywhere else. The original card is locked to the unit but the overall.nds is common within release. May be 0910 / 0915 was what was slushing about on the 2018 post I linked to on this thread. Sorted
