i need to know about the build numbers

[xSpartacusx]

okay so i know the build numbers such as B366, B360, B342, etc all correspond to various emui/android versions..

doing some research this is what i came up with..

B130 = initial EMUI 4.x, present with initial phone setup out of box
B300 = rollback package for EMUI5.0/Android 7.0 > EMUI4.x/Android 6.0
B342 = beta release of android 7.0/emui 5.0
B360 = public full release of android 7.0/Emui 5.0 (out of beta)
B365 = no information to be found.. i want to assume its something like a security patch or something?
B366 = public release of EMUI 5.0.1/ android 7.0 (i dont think all variants of the 6x aka L21, L22, etc have gotten this update according to some threads i have read on here, but i could be wrong)


if any of this info is wrong will someone please correct me, and/or add to this, both for my information and so maybe it could help others?

B130 was the first firmware with EMUI 4 and Android Marshmallow, present on my Honor 6X as initial firmware.

All the rest you've listed is correct. As last build number, i add that there is even a C900B300, and it is the rollback package from Android 7.0-EMUI 5.0 to Android 6.0-EMUI 4.1.
