I can't upgrade my erom

[gruppuso]

Hi.

I have a w850i with R1ED001 Firmware and R3A016 EROM.

I try to upgrade my EROM in R3B015 with XS++, But when it says that it's all ok and I can disconnect and unplug my phone..I see that my W850i have still R3A016 EROM..Why?:mad:

[kondronaute]

it is not possible:)

FOTA has nothing to do with EROM, R3A016 is the latest version ...

[gruppuso]

excuse me, what's mean FOTA?

why do you say that the last EROM is R3A016 when I downloaded R3B015 EROM?

[luzer]

FOTA means Firmware Over The Air; bootloader EROM and FOTA EROM isn't the same
