I highly doubt it. The vendor_boot is different. As soon as I'm done getting this up to my standards I may build for all 3 devices, but for now just the 6a.
I'm on A13 so I'll stick around to see what you cook up. Thanks.
Same experience here - ran zip with FKM and it looked good - went to reboot and boot loop. Same here - boot.img didn't fix it. No biggie - android flash tool ftw.Flashing with FKM results in boot loop for me, flashing stock boot.img didn't fix it. I'll just have to flash full stock firmware with wipe option disabled.
EDIT: Phone really did not like me using the flash-all.bat from firmware to flash it, refused to flash system partitions. Ended up using Android Flash Tool from Google and now the phone is back.
Thankfully the 6a is not my main phone so I can keep testing builds even if they bork the phone. Let me know if you need any logs.
