Maybe you have seen letters like "A" or "Y" attached to the version number on our Facebook posts. These are supposed to indicate the type of firmware we are dealing with. Down below you can find a complete list of firmware types.

Since many people ask us which firmware type they should pick, its not possible to give a general answer. If you want to use the real Flyme with all its (partially Chinese) features the A/Y firmware is the right one to go for. Otherwise and in case you prefer a system without Chinese apps you have to pick the G/I firmware.

U/Q/M/IN firmwares are not really recommendable as they are quite carrier/localization specific. Furthermore U/Q/M firmwares might contain locked bands as well, making the firmware unusable for overseas.


Stable firmwares

Stable firmwares are following a classical version scheme. The first letter discloses the Flyme version, while the latter ones have no special meaning.

Beta firmwares

Beta or "test" firmwares follow a different scheme. While test firmwares first didn't had one, beta firmwares now look like "".

6 = Flyme 6
7 = 2017
5 = May
23 = 23th

So in "text": Flyme 6 beta of 23th May 2017.

Release cycle

Usually the A and Y firmwares are the most frequent update firmwares as they are directly provided by the Chinese Flyme department. Generally beta firmwares (only A/Y) are released bi-monthly and are available on our firmware page on an European server or can be downloaded directly at the Chinese Flyme website.

Stable firmwares appear once every 2 months, however this cannot be taken as a fixed number. Global firmwares are the rarest released ones as the overseas department has no dedicated developers. It is not uncommon for G/I firmwares to take another month after their Chinese base has been relased (stable A/Y firmware).
