S251 Update Offline Update

[medwatt]

Download the S251 update package from this link.

Rename the file to update.zip and move it to the root of your SD card (not internal storage). Boot into stock recovery and update.

If you have TWRP, it will not work. If you have root or magisk, it will not work. You need to reflash the S244 boot and recovery images under fastboot using :

fastboot flash recovery recovery.img
fastboot flash boot boot.img

Do I have to uninstall magisk first ?

Do I have to uninstall magisk first ?

You can try that. If the update fails, you'll have to reflash the stock boot image as the update process might detect a modified boot image. Do you have the boot.img file for S244 ?

Thanks, I have the s244 boot image. I will give it a go tomorrow.

Thanks for uploading this.

Hm, update built on the 7th of November but only contains the 1st of November security updates. Google released further updates on the 5th and 6th of November, with the 6th November update fixing the very serious WPA2 'Krack' issues.

At least this update fixes the blueborne stuff.

You only have one option. You need to re-install the full S244 ROM from this thread: https://forum.xda-developers.com/lenovo-p2/development/fastboot-files-stock-firmware-t3649914

Follow the steps but DO NOT FLASH USERDATA or you will lose all your existing apps and settings. This will restore your system to stock configuration then you should be able to update.
