I try to downgrade Huawei Y9 2019 JKM-LX1 from EMUI 9.1.0 to EMUI 9.0.1 so I can install custom GSI ROM, since EMUI 9.1.0 for Huawei Y9 2019 doesn't allow installing/booting custom ROMs. I know I can do that via Hisuite but unfortunatly there is dumbest thing by Huawei which instantly deletes the dload firmware after flashing, I don't want to download it every time I need to back to EMUI 9.0.1 because my internet is limited. So, isn't there anyway to keep/copy it? at least I want to download the dload firmware from Huawei servers.
