If after flashing your Honor 30 BMH-N19, you don’t get SIM signals, your IMEI shows as null, or the baseband is unknown, then this post is very important for you. All these problems happen because the nvram or nvdata gets corrupted, which is often overlooked during firmware flashing. Here, we will explain how to use SN Write Tool or MTK Meta Utility to restore the original IMEI and make your Honor 30 BMH-N19 fully network-ready again. We will explain every step clearly and simply language.

If the vbmeta.img file is not patched correctly during flashing, many Honor 30 BMH-N19 show errors like secure boot error or dm-verity failed. This post is especially for those who face boot errors every time but can’t find a solution. Here, we will teach step-by-step how to patch the vbmeta file, how to flash it, and how to bring the Honor 30 BMH-N19 back to a stable condition — whether you are using a custom ROM or official firmware.
