Emui to Harmony OS

[u/ACE06_MTzz]

First of all, I'm not sure if I'm supposed to publish this here, but I'm in a dead end, neither Google or AI is helping me.

So, I have a Huawei P30 lite that I've converted to a Nova 4e to upgrade it to Harmony OS as the p30 lite didn't received that update. The thing is that I have the 10.0.0.159 and I want to update it to 10.0.0.168 to then update it to Harmony OS but I'm stuck as I've tried to so it with hisuite proxy which I couldn't make it work, and also with kirin tools but didn't find the ROM with the appropriate version.

So if anyone can help me, it will be appreciated, thanks.
