[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Hello :)

If you are currently on Blackball - fromfuture Weekly KW 45 Lollipop - you have to do following steps:

1) Backup all your user-apps (with data) and important personal data. You can use Huawei Backup or Titanium Backup or both. Dont backup any system-apps (with the exception of User-Apps which you converted maybe to System-App.)

2) For safety make a Nandroid Backup with TWRP from all shown partitions on external SD (it is not possible to restore this, if you change your Android from 5 to 6 - TWRP Backups can only restored on the same Android Version) - going back to Lollipop is a complete other operation after doing all those steps

3) In settings go to "About phone" and tap 7 times on Build number to activate Developer options. In Developer options activate USB debugging and Monitor apps installed by ADB.

4) Downlod and install Minimal ADB and Fastboot on your PC. https://www.androidfilehost.com/?fid=385035244224386526

5) Connect your P8 with USB to your PC and accept the fingerprint on PC and on you Phone. Wait, until Windows install the drivers. If windows cannot install all the needed drivers, download HiSuite from Huawei, install it and connect Phone and PC with HiSuite. http://consumer.huawei.com/minisite/HiSuite_en/index.html

6) Download 2 firmwares for Huawei p8 Gra-L09:

A) Full b200 http://download-c.huawei.com/download/downloadCenter?downloadId=68483&version=238533&siteCode=gr

B) Full b370 https://mega.nz/#F!x1932SbJ!XBWY3rD6q-C8NEwxkGI8Mg

7) Make a folder on your external SD and name it: dload

8) In this folder copy the update.app from b200 first (nothing else)

9) Download the Stock Boot and Recovery (BOOT.img and RECOVERY.img from b200 - only for Lollipop!) https://www.androidfilehost.com/?w=files&flid=140689

10) Search for the Install-Directory of Minimal ADB and Fastboot on your PC (Mostly in C:\Program Files (x86)\Minimal ADB and Fastboot) - copy the boot.img and recovery.img to this directory!

11) Open Minimal ADB and Fastboot with right klick as administrator.

12) Type: adb devices

13) accept the fingerprint on Handy if asking you.

14) Your device should be listed in Minimal ADB and Fastboot with the serialnumber, followed by the word: device

15) Type: adb reboot bootloader P8 restarts in Fastboot-Mode now

16) Type then: fastboot devices - your device should listed with serialnumber, followed by the word: fastboot

17) Type: fastboot flash recovery RECOVERY.img - The Stock EMUI-Recovery for b200 will be flashed now

18) After type: fastboot flash boot BOOT.img - the Stock Kernel will be flashed now (from that moment you cannot boot in your currently system - thats why the full firmware package of b200 must be already in the dload folder)

19) Disconnect USB-Cable from Handy and PC

20) Press Vol+ and Power Button until the Huawei Logo is shown, hold all the time the Vol+ Button until Stock EMUI Recovery is started.

21) With Stock Recovery wipe Cache (Navigation with Vol Button and enter with Power Button)

22) Restart you Phone but press immediately Vol+ and Vol- (together in the middle) and the Power Button

until

EMUI-Software-Installing starts. Now the full update b200 runs to 100% and reboots automatically with EMUI-Optimizing to the system. You dont need to configure anything (Google...) Just skip all the steps until system is ready.

23) Enable Developer options in settings and there activate USB-Debugging. Also in Scurity settings activate "Unknown resources"

24) Connect your phone again to PC and delete on external SD in the folder dload the update.app.

25) Copy now the Full-Firmware package b370 in the empty folder dload

26) Press Vol+ and Vol- and Power Button until the Phone restart and beginn with EMUI-Software-Installing. b370 will now installed on your phone, wait until it is finished. You dont need to configure anything (Google...) Just skip all the steps until system is ready - but allow the Update App to have the needed permissions.

27) You receive an Software-Upgrad via OTA to b382 - download and install this.

28) Enable USB Debugging in Developer Options, connect PC and Phone.

29) In the install directory of Minial ADB and Fastboot (on PC) delete BOOT.img and RECOVERY.img.

30) Download TWRP 3.0.2 https://www.androidfilehost.com/?fid=529152257862681510 and copy it to the Install Directory of minimal ADB and Fastboot. Rename the TWRP to TWRP

31) Start Minimal ADB and Fastboot as administrator, type: adb devices

32) adb reboot bootloader

33) fastboot devices

34) fastboot oem get-bootinfo

33) look - if your bootloader is unlocked like before, or if it is locked now because of the Original Software Updates - if it is locked, you must open it again (for this procedere contact me again) If the bootloader is unlocked, you can flash now TWRP

31) With Minimal ADB and Fastboot flash TWRP:

32) fastboot flash recovery TWRP.img

33) disconect USB form PC and restart p8 with VOL+ and Power Button to TWRP (holding Power until Phone restart and Huawei Logo comes, but VOL+ holding all the time until TWRP is booted already)

34) allow modifications in TWRP, set Language, Time-Zone, Screen-Timeout, 24 hour clock....

35) Make a Backup of the pure Stock now with TWRP (all shown partitions) - if something goes wrong, you can restore

36) Restart you phone, copy the Gratitude 5 Rom to you external SD (and delete the dload folder) Be sure, the MD5 of the Rom is correct on your external SD

37) Boot with Vol+ and Power to TWRP, go to Advanced Wipe and wipe dalvik, cache, data, system and install Gratitude 5

I wish you succes - and this time also a Happy New Year :)
