- | This is a new update from Xiaomi, still featuring **AndroidOne v.9** relase, build **PKQ1.180917.001.V10.0.24.0.PDHMIXM**. | + | This is a new update from Xiaomi, still featuring **AndroidOne v.9** relase, build **PKQ1.180917.001.V10.0.24.0.PDHMIXM**. |
+ | |||
+ | The starting conditions were: | ||
+ | |||
+ | * A/B System Updates status: **Current Slot: ?** (may be it was **A**, because after installation it is **B**). | ||
+ | * Bootloader is **unlocked**. | ||
+ | * **Magisk** and **TWRP** were installed, but may be they were hidden by accident. Infact the installation of the upgrade went OK after a reboot, whereas it should fail because the boot sector is tampered with **Magisk su**. | ||
+ | * **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-v20.4.zip**\\ Current boot slot: _b, unpacking, patching, repacking, flashing new boot image. | ||
