+## Flash stock firmware if you have locked bootloader:
+
+To flash stock firmware, you'll need to use SP Flash tool, which is available [here](https://github.com/moto-penangf/penangf-sp-flash-tool/releases/tag/0.1).
+
+You will also need to download stock firmware from [Lolinet](https://mirrors.lolinet.com/firmware/lenomola/2023/penangf/official/).
+
+Open SP Flash Tool and use the scatter file (.txt) you find in the firmware archive.
+
+Select DA_PL_NO_CERT_V6.bin as the Download Agent.
+
+**Untick the preloader partition**, unless you're installing a new version of stock firmware compared to the one you had.
+
+:::warning
+**MAKE SURE YOU'RE NOT SELECTING DOWNLOAD+FORMAT ALL, JUST DOWNLOAD ONLY**
+:::
+
+Press the Download button.
+
+## Flash stock firmware if you have unlocked bootloader:
+
+You can flash stock firmware by using Fastboot
+
+Download the latest firmware from [Lolinet](https://mirrors.lolinet.com/firmware/lenomola/2023/penangf/official/)
+
+:::warning
+DO NOT execute any other commands apart from the one listed below, or you might brick your device.

+
+$ fastboot flash vbmeta_vendor_a vbmeta_vendor.img
