What's the difference between GM21AA and BA?
Why the need for two ROMs? @Funk Wizard
I live in Australia and on the at Australian OnePlus download page it has the BA version, which should I install
I'd assume that if you see tha BA version on the Australian Oneplus website Australia is being supplied with the EU variant.AFAIK there are different build tags for different variants and 9.5.5 was released for the EU Region where as 9.5.4 for Indian Region and 9.5.6 was a bug fix build on top of 9.5.4 for the US Region.
GM21AA: GM1911: India & GM1917: Global/US Unlocked
GM21BA: GM1913: EU
GM27BA: GM1920: EU 5G
GM31CB: GM1915: T-Mobile (Carrier Locked)
Thus for now Latest builds are as follows:
9.5.6 US Region
9.5.5 EU Region
9.5.4 Indian Region
Hope that clears some air :fingers-crossed:
@Funk Wizard
Maybe it would be best to add all variants to the OP, what do you think?
