I have recently purchased my first Xiaomi device (Mi 8) and so far I am impressed. I currently have a locked bootloader but have only got 15 days or so left until it is unlocked. In the mean time I was interested in upgrading my current ROM (China Stable ver 10.0.9.0) to China Developer ROM (ver 8.11.15). From what i have read I was under the impression that changing between a stable and developer/beta rom of the same region (EU, Global or China) was allowed.
I have tried doing it by the local update method which didn't work and then via XiaoMiTool to which I got to the very end of the process and was left with the following screenshot (image below) which states that I need to unlock the bootloader in order to update to China Developer ROM, is this correct? Does anyone know of any way I can install the latest China Developer Rom via another method without unlocking bootloader? Could I sideload it using XiaomiADB?

Any help would be appreciated.

You can update from china stable to china dev. Just download the latest china dev and select it from the phone`s updater. You don`t need unlocked botloader for this. I did it on my mi5 and mi8, but this will format your phone.
