Your review of the M300 and the boot.img/fastboot Rom was the deciding factor in my purchase of the M300, thank you very much.
I purchased the M300 and am waiting for it to ship.
Since Hiby doesn't offer previous firmware directly, I think I need a backup of the previous version.
Can you help me with this when my M300 arrives? (If I receive that with a 1.2 or lower version...)
I don't know how to use the DSU, but I know how to do simple things like unlocking the bootloader, rooting, and installing GSI.
@Joe Bloggs Or can Hiby provide me with older firmware (from the very first version)?
