I completed the stock file system tests with all external media storages formatted to FAT32 with no issues whatsoever. Beforehand, installed kernel v0.2.3a that I never tested before, just the experiment6 version, and managed to crash the kernel on USB insertion while the screen was on.

I can now with certainty confirm that all dirtysanta versions have all werewolf file system issues plus the USB fatal error that werewolf doesn't suffer from.

Pattern: After reflashed jahlex>wereworlf kernel to recover from DirtySanta v0.2.3a I made a TWRP backup which I never managed to restore it, when went back to the previous backup that DirtySanta was never flashed on, everything just worked.

Read your previous post again and realised I never tried the -c flag alone the way you described. I always flashed an image of cust by fastboot method by dumping it first from my TWN variant.

Your screenshot does't lie. After hours of testing I know why you were sucessful but I wasn't. Both of us were right but it depended on the factory version (also known as Buyer), firmware region, and the cust partition is being flashed over the installed firmware. You are right, because the firmware you flashed was in the same zone as your phone's factory region setting and flashed a cust partition matching your phone's factory region setting. I was also right because, in my case, both the firmware and cust partition didn't match the phone's factory region's zone setting. If the "zone" is not matched, the software version string will always end with GLOBAL-COM.

Attached four screenshots as I tested the above explanation before posting;

1. Flashed 10f-TWN cust partition over 10f-AME which is not in the same zone. Please notice how the firmware version was incremented by 1 to V11. So weird.

2. Just to prove that I own the TWN version too.

3. Installed 10c-TWN on H990DS AME to start rooting it to install a 10g firmware from Singapore by kdzwriter

4. Even after flashing 10f-TWN cust partition the software version remained as GLOBAL-COM.

Even after flashing 10c-TWN (no 10c was released for AME) I didn't get NT-Code error messages. My attempt was to match the software version so that I can keep one version of everything for both phones. The idiots, the online retailer, that I bought the phones from, a month apart, sent me the AME instead of TWN. I found out too late but I'm very disappointed to have a dent in my plan now.

Edit-01

Added fifth test with screenshot.

I forgot to do the obvious and last test. Flashing/overwriting with the right cust partition, in this case AME, over the firmware from different region and zone. As you can see the format changed to the proper format, like yours, but 10g changed to 10f, unlike yours. All along, I was trying to get V10f-TWN-XX. This test revealed, if "both" cust and firmware versions don't match phone's factory region then the software version number would end with GLOBAL-COM. However, if cust partition matches the phone's region setting then the software version format will be region specific, i.e. V10f-TWN-XX, with unpredictable version number as I have proven twice already.

Happy Official Nougat Xposed Release Everyone.
