May I ask if it is possible to support, such as old device “huawei GR5 2017”, by a ROM from the community, because it will be great if you can give this little device a new life, thanks in advance.
This may be possible, and may even be done already. Please can you confirm, if this is your phone?

If your phone is this model, then it will be straightforward to build an up-to-date q ROM
