I have a Sony Xperia XA2 Ultra, and I was install LineageOS in it.
After October 2019, LineageOS doesn't work well (in my case, fingerprint doesn't work) IF I DON'T install the new 50.2.A.0.400 firmware.
I'm using Emma flash tool for that, but seems like Emma only flash the slot A, not slot B.
I was change the active slot (fastboot set_active b) but when I reconnect with Emma, seems like it's forced to use the slot A instead of B.
Can I use flash tool for flashing both A and B slots?
How?
I have the Emma flash tool: 2.19.16.201912061438 version
