For the Huawei Nova 5T (YAL-L21), "verified" custom ROM support is extremely limited because Huawei officially terminated its bootloader unlock code service in July 2018. Without an unlocked bootloader, you cannot install a custom ROM. The Bootloader Unlock Barrier

Since there is limited support for dedicated custom ROMs for this specific device model, the most common way to get a "verified" Android experience is through GSI (Generic System Images).

It checked every partition against a cryptographic key. If the key didn’t match the factory signature, the phone would refuse to boot. It would rather die than run untrusted code.
If you want, I can generate a ready-to-post forum thread (with templates for model, exact files, checksums, fastboot commands, TWRP logs, and step-by-step commands). Tell me your exact Nova 5T model/codename, ROM build name and links, and checksums and I’ll produce the complete copy-ready post. Export OEM unlock code (if required by your
