2. 查看 recovery 的报错信息，发现 fingerprint 不一致

1. 机器的 fingerprint

C:\Users\fadi.su>adb shellK9:/ $ getprop |grep displaygetprop |grep display[ro.build.display.id]: [L38043_ROW_OPEN_USER_M6762_O_MTK_S104_18H16]K9:/ $ getprop |grep fingergetprop |grep finger[lava.mmi.fingerprints]: [yes][ro.bootimage.build.fingerprint]: [Lenovo/L38043/K9:8.1.0/O11019/1534425307:user/release-keys][ro.build.fingerprint]: [Lenovo/L38043/K9:8.1.0/O11019/1534425307:user/release-keys][ro.vendor.build.fingerprint]: [Lenovo/L38043/K9:8.1.0/O11019/1534425307:user/release-keys]

2. 本地升级包的 fingerprint

这个Ok

ui_print("Source: Lenovo/L38043/K9:8.1.0/O11019/1534425307:user/release-keys");ui_print("Target: Lenovo/L38043/K9:8.1.0/O11019/1534448187:user/release-keys");ui_print("Verifying current system...");getprop("ro.build.fingerprint") == "Lenovo/L38043/K9:8.1.0/O11019/1534425307:user/release-keys" ||    getprop("ro.build.fingerprint") == "Lenovo/L38043/K9:8.1.0/O11019/1534448187:user/release-keys" ||

3. 服务器的 fingerprint

不一致，升级失败

getprop("ro.product.device") == "K9" || abort("E3004: This package is for \"K9\" devices; this is a \"" + getprop("ro.product.device") + "\".");ui_print("Source: Lenovo/L38043/K9:8.1.0/O11019/1534188326:user/release-keys");ui_print("Target: Lenovo/L38043/K9:8.1.0/O11019/1534274677:user/release-keys");ui_print("Verifying current system...");getprop("ro.build.fingerprint") == "Lenovo/L38043/K9:8.1.0/O11019/1534188326:user/release-keys" ||    getprop("ro.build.fingerprint") == "Lenovo/L38043/K9:8.1.0/O11019/1534274677:user/release-keys" ||
