[Huawei P9 Plus ROMs, Kernels, Recoveries, & Other ] OldDroid:
This is only for Huawei P9 Plus (VIE)

OpenKirin presents unofficial TWRP for stock EMUI 5.x with decryption support.
Intended for usage on stock emui 5.x in combination with unlocked bootloader and
modded boot image with disabled dm-verity (depending on what you want to do).

[COLOR="red"][B]WARNING:[/B] since 3.1.0-2 update we've enabled image flashing to special partitions -
not just /recovery or /boot partition.
That means your device could be bricked in a few seconds if you do not pay attention
or don't know what you're doing. (Noobs please stay away out of this section!)[/COLOR]

Installation Instructions

1. Enter fastboot mode on unlocked device
2. flash recovery using the following command: fastboot flash recovery twrp-3.1.1-1-vie.img
3. reboot to recovery!
