 ===== Rooting =====
-If your phone has the build number **BV5300_EEA_TE105_V1.0_20230705V11**, you can download the following archive containing the already patched **boot.img** and **vbmeta.img** images. Obviously you must trust me that the images don't contain malware or alike. If you don't trust me, you have to execute all the steps by yourself: **{{.:bv5300:bv5300_eea_te105_v1.0_20230705v11_magisk-26.1-boot.zip|BV5300_EEA_TE105_V1.0_20230705V11_magisk-26.1-boot.zip}}**.

 The standard rooting procedure (see [[https://topjohnwu.github.io/Magisk/install.html|installing Magisk]]) failed; **patching the boot image** and **flashing** it back into the phone worked as expected, but **flashing the vbmeta image** with the ''%%--disable-verity%%'' and ''%%--disable-verification%%'' options did not work: the bootloader still checks the signature of the images and because the boot image is tampered, the phone enters a **bootloop**. The bootloop occurs also if you disable //verity// and //verification// into the original vbmeta image, keeping the original boot image.
