Huawei is so far staying true to updating the phone, at least with security patches. I respect that.
Official links for download:
Dual SIM: FULL or OTA
Single SIM: FULL or OTA
How to install:
- Put the UPDATE.APP from the .zip in "dload" folder in root of SD card
- Make backup (won't be needed normally)
- Install stock recovery (you can extract the recovery image of this build with Huawei Update Extractor and use fastboot to flash it)
- Wipe data/factory reset
- Hold POWER, VOLUME UP and VOLUME DOWN at the same time. The update process will start.
Alternatively, you can dial *#*#2846579#*#* and select: Software Upgrade > SD card Upgrade > confirm the installation
(Also you can flash the attached zip to get "Local Update" option back in the upgrade area of settings.
Apparently you also can flash the FULL zip in TWRP.
