+ | ===== August 2020 security update ===== | ||
+ | |||
+ | This is a new update from Xiaomi, still featuring **AndroidOne v.9** relase, build **PKQ1.180917.001.V10.0.24.0.PDHMIXM**. The upgrade was downloaded nightly over the WiFi. It seems impossibile to prevent such automatic download: I did not find any settings to prevent automatic upgrade download. After downloading, | ||
+ | |||
+ | The starting conditions were: | ||
+ | |||
+ | * A/B System Updates status: **Current Slot: ?** (checked via TWRP => Reboot screen). | ||
+ | * Bootloader is **unlocked**. | ||
+ | * FIXME **Magisk** v20.1 and **TWRP** 3.3.0 installed? Into **which partition**? | ||
+ | * **System partition** was the stock one: root privileges were never used to tamper the **/system** hierarchy. | ||
+ | |||
+ | After the upgrade, I did the following to get **root again**: | ||
+ | |||
+ | * adb reboot bootloader | ||
+ | * fastboot boot twrp-3.3.0-2-tissot.img | ||
+ | * Verified from TWRP => Reboot: **Current slot: B** | ||
+ | * adb pull / | ||
+ | * adb pull / | ||
+ | * TWRP ⇒ Install ⇒ **twrp-installer-3.3.0-2-tissot.zip**\\ Running boot image patcher on slot a and b. | ||
+ | * system reboot | ||
+ | * adb reboot bootloader | ||
+ | * fastboot boot twrp-3.3.0-2-tissot.img | ||
+ | * TWRP ⇒ Install ⇒ **Magisk-v20.3.zip**\\ Current boot slot: _b, unpacking, patching, repacking, flashing new boot image. | ||
