Gonna brick my device with this 10/10 , if someone tests it post some pics on a understandable language and an instruction please. Most of us aren't chinese users....
Obs: This is for CHINESE firmware only.
About installation: its flasheable zip file. This mean you can flash via TWRP. I assume you must be on unicomelectric/cn (vendor/market). I personaley followed this method: install B230, then update to B240, then update to B556. After that i flashed custom recovery from whitch i flashed this zip file.
1. Its plain with chinese apps, which probably are very usefull, but i cannot speak chinese, so there are the option to uninstall those apps.
2. Always you can install Huawei App HiApp from where can install google play store for example. But its very usefull for update huawei preinstalled system apps too, for whitch on play store arent any updates.
3. Huawei App Store (for official huawei apps): Huawei App Store
Point 16 Are the System Patches part of the let's call it 'mod' or of EMUI?

Can you already install the ROM?
I doubt this is only for ALE-TL00 and cannot be installed on ALE-UL00
I changed the screenshots with my phones ones.
@ sokkoban: probably you remember: i was the one with chinese firmwares ale-ul00c00b551. And YES. You can flash over b556 chinese fw. One notice at flashing process says error mount blck...39 and 40 partition or what? Anyway the phone works well.

Thx for the answer my friend I will probably install for test
One note: B558/B556 its for ALE-TL00/ALE-UL00. So i assume their are interchangeable.
B556/B558 at club vmall - chinese forum
now i find, that the screen gesture settings are missing: double-tap wake-up, letter painting shortcuts, rotate the phone for mute alarm or calls. I wonder if these settings can be enabled or not via editing build.prop (or maybe local.prop)?
- Huawei-Swype its missing too, but we can install it: Huawei-Swype

Damn, I Will just wait for officiel OTA then, Im on B556 now and I fixed the model number too
I'm not using gestures so for me everything is working fine Thanks!
I can't enable or activate Hisuite after upgrading to v551 and v558 for restore data. Anybody with this problem? How to resolve?
this build quality is worse than 551. Very unstable bluetooth connection, lack of some good apps (swype, etc). So after two days back to 551.
b551 is the best version, specially for battery life , i had 6h30 screen on time and still have 11%

Huawei P8 Custom ROM
* MagicArrow *
Version Two
Magisk Edition and Classic Edition
Teamwork by Tecalote and KangV
Based on the European firmware b398 - only installable, if you are already on Marshmallow Firmware (Android 6)
Developed on GRA-L09 C432 - but it should run on all GRA-xxx models and regions due to my modification
Thread for German Users: https://www.android-hilfe.de/forum/root-custom-roms-modding-fuer-huawei-p8.2257/huawei-p8-rom-6-0-emui-4-0-3-magicarrow-v2-by-tecalote.819399.html
Well, you've been waiting long enough I am pleased to present you the new version of Arrow under the extended name "MagicArrow"
1) Difference between Magisk and Classic Edition:
The Magisk Edition was made to have a safteynet capable device that still offers much more features than Stock Firmware ... It has the same features like Classic Edition, with one difference: Outward It looks as if you had not unlocked the bootloader .... Apps like Pokemon Go, various banking apps - which does not work anymore on rooted devices should work in this Rom
However, you can not install Xposed Framework in the Magisk Edition without losing the green safetynet! There is the systemless Xposed Framework by topjohnwu, the developer of Magisk and it works, can be easily downloaded and installed in the Magisk Manager via modules (SDK 23) - but - there is currently no way to pass safetynet with a modified custom Rom together with Xposed Framework! For this reason, the installation pool in K-Settings for Xposed is removed from its function.
Attention: Update the preinstalled Magisk with newer Version 15.3 flashable zip made for this ROM: https://forum.xda-developers.com/showpost.php?p=75178940&postcount=871
Then look in the Thread for new posts about future Updates.
The Classic Editon is rooted with SuperSU and has same features, but you cannot bypass safteynet check. However, who does not run apps depending on this "questionable" service will have the same joy with this Rom. The advantage of the Classic Edition is: You can install from K-Settings Wanams Xposed Framework 87.1 and use a lot of Xposed modules ...
2) Requirements and information for this Rom:
If you want to have the best of this Rom, then it would be necessary to start completely clean - means from Custom Rom back to Stock Firmware b398 - With the exception of devices for which there is no more recent firmware than b370. An EMUI Custom Rom is as good as the before installed Firmware in the background. In principle, only system, cust and kernel will be flashed with the Rom zip. The original Firmware update a lot more, like modem etc. Therefore, the Custom Rom works best if you start from latest firmware for your device on which the Rom is based.
If you have already latest official Huawei Stock Firmware installed, it is less work...
I really dont recommend to flash dirty this Rom directly from Arrow v1 or if you stay on older Firmware. System and Apps will be wiped with the installation script. So you cannot keep your previous apps and data, you have to install them new.
You need the latest TWRP:https://dl.twrp.me/grace/twrp-3.1.1-0-grace.img Do not use older ones!
The bootloader must be unlocked. Pick up the Huawei unlock code, because it is always valid for the same device. If you do not have an unlock code from Huawei and have problems to get it from Huawei Website, recently you can call regional Huawei service hotline and get the code by mail during 24 hours.
3) Installation guide for the MagicArrow:
1) Backup your apps and data from your current Firmware or Rom - but only User-Apps and not System-Apps. You can use Huawei Backup as well as TitaniumBackup. (Dont restore any System-Apps from previous system in the new Rom - example: if you use Huawei Backup dont backup Phonemanager, but you can backup desktop layout, sms, calendar, User-Apps etc.) Dont backup and restore Chat-Apps like WhatsApp, Viber, WeChat, Facebook and so on - use their inbuilt Backup Function like Google Drive Backup (its different, some Apps are storing everything on their server like Telegram) You must install and register Chat-Apps new on your new Rom. If you dont do that, Push-Notifications cannot work.
2) Make a backup of important folders and files from your internal storage (DCIM, WhatsApp folder, Downloads....)
3) Download Firmware update.zip - depending on the device model - and unzipp it on your PC - you receive META-INF and UPDATE.APP
GRA-L09C432B398: http://update.hicloud.com:8180/TDS/data/files/p3/s15/G985/g104/v88316/f1/full/update.zip
GRA-L09 with other Cust: http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=GRA-L09&firmware_page=0
Other GRA models: http://hwmt.ru/hwmtsite/firmware-database/?firmware_model=GRA&firmware_page=0
4) Copy UPDATE.APP and META-INF into a folder on the root directory of your external SD which must have the name: dload
5) If you are on Stock Firmware, not rooted you can directly update your Firmware. But go to step 6
A) If you are on Stock Firmware, but rooted, with TWRP installed and Xposed Framework installed, uninstall first Xposed Framework, reboot to system, after unroot your device, restore original boot.img and flash the original Huawei Stock Recovery.
B) Arrow Editions: If you have Xposed Framework installed, uninstall Xposed Framework, reboot to system (15 min) - after go to step 6
If you are on Arrow v1 Classic Edition without Xposed Framework, flash Huawei Stock Recovery from K-Settings /more settings / flash recovery - flash official recovery. You can reboot directly from here to Stock Recovery.
If you are on Arrow v1 Magisk Edition without Xposed Framework, flash with TWRP Magisk Uninstaller: http://tiny.cc/latestuninstaller and after flash Huawei Stock Recovery b391 (by choosing img): https://www.androidfilehost.com/?fid=529152257862705190
- go to step 6
6) Press Vol+ and Power Button until phone reboot and hold this position until phone boot up to Stock-Recovery. Here you do first "Wipe Cache Partition" and second "Factoryreset" - go to step 7
7) If you start EMUI Update from here, just go to Restart and press Vol+ and Vol- (in the middle down and hold this position), wait until phone reboots and EMUI Software Installing begin (of course, update.app and meta-inf must be already in dload folder)
If you was back in system between you can start update with pressing down Vol+ and Vol- in the middle and at the same time pressing Power Button. Wait until phone reboot and you see Huawei Logo. Now you can release Power button, but you must keep holding all the time the pressing down postion with Vol+ and Vol- until EMUI Software Installing begin. After some time your firmware is updated and restart to system. Dont make an account yet, just make short setup.
8) Open settings /about phone and klick 7 times on build number for enabling developer options. Open developer options and in there enable USB Debugging. After go to settings / (advanced) settings and enable "unknown sources"
9) Connect your device with USB to your PC and let windows install the drivers or install HiSuite (which installs drivers if windows cannot recognice) You need the USB Connection. With Minimal ADB and Fastboot in administrative mode you can flash now the newest TWRP, which I have linked above.
10) Disconnect your device from USB Cable, soon TWRP is succesful flashed
11) With Vol+ and Power Button reboot your device to TWRP - this step is important if you want to keep TWRP
12) Allow system modification and go to ADVANCED WIPE - choose in the first step ONLY internal Storage (nothing else). Do not wipe internal Storage together with the other partitions in step 14! Soon internal storage is wiped, go back to main menu and restart the recovery. You should get the Root Permission request from TWRP "Allow system modification" once again, allow it and open settings to configure (24h clock, language, time zone, etc) If you dont get the Root Permission request from TWRP yet, you will get it after next boot to TWRP.
13) Now copy MagicArrow.zip to your external SD - Attention: If you want the boot sound to be played on the phone - before flashing the Rom, sound must be switched on!
14) Boot to TWRP and go to ADVANCED WIPE - Wipe following partitions:
Dalvik/Art Cache
Cache
Cust
data
system
15) Go back to main menu and flash MagicArrow. After flashing is done, reboot system without wipe of dalvik/cache. As you know, the first boot process can take up to 15 minutes (just like installing the Xposed Framwork)] After boot to system and first setup - you have to make some IMPORTANT STEPS (see next Point) before you restore /installing your apps and adjust your phone.
4) Important information for the Magisk -Edition:
During first setup you may receive a root-rights request, if so, confirm this. After first setup - please do not open the Magisk Manager . Before you do anything else,open settings / about phone and klick 7 times on build number to enable the developer options. Open developer options and in there enable USB debugging! Then go back to Settings - in the b398 there are the extended settings with the short name: Settings. In it, please enable " allow unknown sources "
At this point restart immediately your P8.
Now open the Magisk Manager, the app is looking for updates - to speed this up, drag from first white field (like refresh of a website in Chrome) with the finger pressed down - the manager is up to date. Makes a query of the Safteynet = green.
Then you go in the Magisk-Manager left to the Controll-Pannel to settings. Do not change anything, with one exception: enable systemless hosts! This step is very important. Then immediately the second reboot .
Next open AdAway and activate the hosts file (download files and activate the advertising block) - then the third reboot .
After open AdAway again and see if the hosts file is active, if it is, all well, if not, download the hosts files once again and restart P8. (Sometimes another reboot is necessary at the point) Only when AdAway is green (activated) - then the safetynet is passed by. You can now again check in the Magisk manager safetynet = green - if you do not these steps, you can break the safetynet. In addition, root and apps can be blocked!
As you know, Magisk uses his own superuser, integrated into Magisk Manager
For some reason if you have problems with safetynet with some apps, just download the following module in the Magisk Manager in the Control-Pannel under Download:
Universal Safetynet Fix
Otherwise, please do not download any modules, you do not know if they run and what they do.
Two modules are preinstalled - please leave this, otherwise this Rom does not function properly with K-Settings!
5) Important information for the Classic -Editon:
The Classic edition gets systemless Root during the installation by SuperSU 2.82 SR1 (SR1 has an integrated update for Huawei devices). After Rom is flashed and you restart phone, the first boot process will terminate, the device will restart once again - this is normal because of systemless rooting . Why systemless this time? Because of compatibility with SuperSU. The new versions of SuperSU are rooting always systemless. If there is the next Final version of SuperSU, you need only flash the zip in TWRP and there are no problems with the update.
To enable AdAway , just download the AdAway ad block (hosts file) and reboot the P8 - but after rebooting, please open AdAway again and see if it worked the first time - otherwise just download again and restart the device once more. The second time it fits. AdAway is controlled by the systemless root using an init.d script that mount the hosts file systemlessly and this script is usually only active after the second restart. If you ignore this step, you can block root privileges.
6) Features:
• VoLTE and IP-Calling enabled - disable it, if your mobile provider dont support it!
• Push notifications working - Enable WhatsApp, Telegram... as protected apps and enable Wlan and mobile data during "sleeping mode" as always on
• Most Gapps contained in system debloaded - please dont flash any GApps, just install it with Playstore (Core GApps and settings are present in the Rom)
• System is deodexed
• pre-rooted: Classic Edition by Chainfires SuperSU 2.82 SR1 - Magisk Edition by topjohnwuMagiskSU 13.3
• BusyBox 1.27.1 - Please dont change this BusyBox to any other (not Stericson, not JRummy...)
• Call Recorder - You can enable recording manually, if a call comes through with the memory icon in dialer - or constantly in dialer settings
• Some nice themes, BlackPyramid ...
• K-Settings - as usual with extended restart menu
• MiXplorer (very powerful Root-Explorer) and TitaniumBackup (can store backups without any problem through storage SD instead of document provider)
• Dolby / Atmos for Teamwork with Viper4Android - best experience with BlackPlayer (or similar) but not Huawei Music App
• Security patch level 1 July 2017 - all known Stagefright Security holes are closed
• Multiwindow mode - you can start this mode with long tap on square in navigation bar. Close the Mod in the middle with the turquoise symbol.
• Viper4Android (enable it via K-Settings) can be linked to its settings permanently in notification bar for quick access. - as usual.
• Xposed Framework of Wanam included in K-Settings, Installation start from there, reboots automatically. The Restart needs about 15 minutes.
• VIA Browser instead of Chrome
• AdAway - newest release
• And much more...
7) Phone Manager and the app PMPlus:
Phone Manager does not include the Autostart Manager in European Firmware. The advantage is: you do not have to worry about anything, everything is controlled automatically - and also works. But the battery consumption is slightly more, since all apps wait in the background to be called.
With the app PMPlus, you can activate the Autostart Manager in the Phone Manager. To do this, start the app, go to Installation and as soon as the succesful message comes, close the app (can be uninstalled thereafter). Now, on screen two of the Phone Manager, the entry "App auto-launch" appears!
But NOTICE - through this upgrade will initially set ALL Autostarts to 0 ! You must manually enable the most important apps in App auto-launch - all apps that should receive push notifications - and, most importantly, SuperSU in the Classic Edition and Magisk Manager in the Magisk edition. Otherwise Root permissions do not work!
Advantage: You have control over which apps should not start at system start or in the background (if you need it rarely)
But you must always remember to activate a newly installed app there if necessary. Example: Amazon, E-Bay, PayPal - some of these apps are coupled and not only need the autostart to work , but also the so-called " app activation " (which appears in Autostart Manager when such apps are installed)
Disadvantage: If the apps are not configured correctly in the mask, you have more trouble than good. So, if you're not control freaks, then let's keep your fingers out of it.
But if you want to activate this function, it is recommended to do it at the end, if you have already installed all the apps you are using and not before!
8) Disable Chinese Letters:​
The Rom is European, but the K-Settings are from KangV. Thats why the Lunar component is installed in K-Settings (these are the only Chinese letters in this Rom).
To hide these, go to K-Settings:
1) Lockscreen and desktop settings and disable: "Lunar Calendar" and at "Desktop weather lunar"
2) Notification settings - disable: "Show statusbar lunar"
9) Save Battery:
NFC (with Android Pay) ist enabled by default - disable it and enable it only for the time you need it
VoLTE is enabled by default - disable it, if your mobile provider dont support it
Location Settings (menu: scan settings) disable WLan and Bluetooth Search while Wlan and Bluetooth is disabled, Navi Apps are working also without this setting.
Performance is enabled by default - change this in Akku-Manager (part of Phone Manager) to SMART
With "auto app-launch" (if you have installed) you can disable Apps which you use just sometimes.
Bluetooth enable it - if you use it and disable it - if you dont need it at the moment

Last Thread Update: 03.01.2018
Right settings for Push Notifications and install manual for Stock Firmware Update
Right Settings to make Push-Notification work for Chat-Apps like WhatsApp:
Settings with Phone Manager:
1) Once you have installed with PMPlus the Autostart-Manager called: App auto-launch as a part of Phone Manager- WhatsApp, Viber and all those apps must be activated!
2) Activate these applications also in Protected apps
3) In Notification center activate for these applications - Priority display, Status bar, Banners and Lock screen
4) If these apps are available in Dropzone management - activate them
5) In Phone Manager /open Akku-Manager (Remainning) and in this mask open the settings-symbol above - deactivate Power-intensive prompt and deactivate "Close excessively power-intensive apps" and some lines below:
Activate: Keep Wi-Fi on when sleeping ALWAYS - Keep mobile data on when sleeping
Settings with Permissions and Notifications:
1) Open settings /Apps and search for WhatsApp. In this mask you find Permissions- and Notifications-Settings , go inside of both and set the needed permissions for the app and also "Alllow Notifications" and Priority display
Settings in Developer options:
1) one point after "use legacy DHCP client" - set: Mobile data always active
Additional Settings:
1) Settings /More - Open Mobile network and set: Mobile data - and Enable always-on mobile data
2) Open Settings /Wi-Fi and go to menu in the right corner below "Advanced setting" - set: Keep Wi-Fi on during sleep ALWAYS
3) Open Settings /Notification panel & statusbar - activate: Notification panel "Allow notification panel to be opened from the lockscreen if not password protected
4) Open Settings /Screen lock & passwords - activate "Show detailed notification info" and activate optional "Notification turn on screen"
For most users of ARROW Push-Notification for Chat-Apps are working now as they should (whitout converting them to system-apps like in Gratitude before) -
And for most users battery life is much more better than in Gratitude or in Stock Firmware.
But for some users not!
- Notifications coming not constant or not at all - andBattery life is worse than before - How can that be?
Answer: The complete different initial situation and sometimes also the settings.
Initial Situations (examples):
User A updated Lollipop with Stock Firmware to Marshmallow a long time ago (example: from b200 to b317) - after he was going to Custom Rom "Gratitude" - and from this time he was never back to any Stock Firmware and flashed new versions of Custom Rom always dirty.....
User B was also last on b317, after on "Gratitude" and flashed every new version clean, with Fullwipe.....
User C was last on b321a, after on "Gratitude" and flashed every new version clean, with Fullwipe but Arrow dirty....
User D was on Gratitude 5 and then he go back to Stock Firmware b370 - from there with OTA to b382 and after he flashed TWRP and did a Fullwipe before installing ARROW - this user has the best starting position! And for this user ARROW should work as provided
Why?
Custom Rom can only modifiy on Huawei Devices following partitions: system - cust - vendor (and nothing else!) Modem Updates, Updates for Push-Notifications and other sync services or battery software updates are coming with official Firmware!
The best performance for ARROW is given, if your Marshmallow Firmware and Bootloader and Modem.... is also up-to-date.
There is no need to do following steps, if you have flashed ARROW and everything is fine for you.
I would recommend to go back to Stock Firmware as an step between - before flashing ARROW - for Users which come from Gratitude and for Users which have already ARROW installed and issues with Push-Notifications or too much battery drain!
(STOCK-RECOVERY AND UNROOT IS REQUIRED - AND YOU NEED ALWAYS FULL FIRMWARE FROM CUSTOM TO STOCK) - see install manual below!
The Full-Firmware you download (no OTA Files please) should be minimal b370 (which is available for all models). After this EMUI-Installing with reboot to system you can use in settings the Update-App to receive the next OTA Update and install this also. If the Update-App says after installing "no more Updates available" it is okay!
Normally you can use one Full-Firmware above b370, for GRA-L09 it is b382 - alternatively you can use b391 - but a higher version like b391 seems not work (cause Rom is based on b391)

Install manual:
To go back to Stock Firmware you have to do following steps:
1) Backup what you need to backup! Use Huawei Backup and also Titanium Backup. NOTE: But dont restore in the new ARROW then system-apps or data from system-apps from previous system! Restore only USER-APPS. For Chat-Apps like WhatsApp, Viber, Skype use the built-in Backup function - but keep or backup the folder from those apps on internal memory (because you need them on the same place if you reinstall those apps)
Battery must have minimal 80% doing those steps....
2-A) Users of Classic-Edition: Open K-Settings /more settings /flash recovery - Flash official Recovery (grant Root-Permission) - this flashes Stock Recovery in half a second.
2-B) Users of Magisk-Editon: Please go to TWRP and flash Magisk-Uninstaller.zip to unroot your Phone. Users of Gratitude Magisk Edition should also flash unsu.zip (both linked in OP) After reboot make a connection with USB to your PC. With Minimal ADB and Fastboot program (on PC) flash Stock-Recovery. If you dont know how to do, ask me in this Thread. Download: https://www.androidfilehost.com/?fid=529152257862705190
If you have Xposed Framework installed - uninstall it (Magisk Users in Magisk Manager/Modules - Classic Users in K-Settings /Xposed Settings /Install Xposed confirm - Reboot needs about 15min)
3) Download the Full Firmware for your model, unzipp it on your PC (mostly you get update.app and meta.inf)
4) Create a folder on internal memory or external SD and name it: dload
5) Copy only update.app and meta.inf (if meta.inf is present) in this folder. After DISCONNECT USB from Phone!
6) Reboot to Stock Recovery - with Restart menu (also possible with pressing Vol+ and Power-Button at the same time as long until Recovery is displayed)
7) Wipe Cache with Stock Recovery (it uses another engine than TWRP) and do after a Factory Reset. There is no need to restart the phone to system now. Go to:
8) Press Vol- and Vol+ (in the middle) and Power-Button at the same time, until phone reboots and EMUI-Software-Installing is displayed
9) Let the EMUI-Installing finishing - it reboots automatically to system and starts the EMUI-Optimizing - wait until Language-Selection is displayed. Make a short set up (You can skip the most) - but it is important to arrive the homescreen.
10) Go to Settings / About the phone and tap 7x (times) on Build-Number. It activates developer options.
11) Go to Developer options and activate USB DEBUGGING - after open Advanced settings /security and activate "Unknown Sources"
12) Connect Phone with USB to your PC (Accept the Fingerprint query with "always" on your Phone) Look, if Windows installed the right drivers so you have access to phone - if not install HiSuite http://consumer.huawei.com/minisite/HiSuite_en/index.html and make a connection with HiSuite. Allow installing HiSuite on Phone. If you have access now, close HiSuite (also in Background).
13) Copy ARROW-Rom to your Phone.
14) With Minimal ADB and Fastboot flash TWRP: https://www.androidfilehost.com/?fid=529152257862681510 - if you are unsure with the right commands, ask me in the Thread.
15) DISCONNECT USB Cable now from your Phone
16) Press Vol+ and Power-Button at the same Time until phone reboot (at the moment, Huawei Logo comes you can leave Power Button, but keep holding Vol+) Reboot to TWRP takes a while
17) Set up TWRP (allow modification, set language, screen timeout, time zone...)
18) There is no need to wipe internal SD (but if you like to do this, do it at first and restart after TWRP - then you must setup TWRP again)
18) Go to Wipe, Advanced Wipe and wipe: Dalvik&Cache, Cache, data and system
19) Install ARROW Rom
20) Restore User-Apps, but dont restore any System-Apps (or data from it) Chat-Apps install from Playstore, and use the built-in restore function.
ARROW should work now as ist should!
Men like always the best work!! I already intalled the Arrow ROM... At the moment working excellent... Congratulations :highfive:

Hi This is interesting - I am at home in two hours and loading up the apk for you.
I flashed both versions of the Rom about 20 times for testing several things and had always the App preinstalled...
I think it is cause of TWRP.
After making a Nandroid Backup before flashing the Rom it has problems to unmount and remount partitions.
If data was not mounted correctly, the App would not be preinstalled - cause it should go to /data/app
That's why I recommend, after making a Backup to Restart TWRP (reboot Recovery) before flashing the Rom...

Hi
Written in OP
"In ARROW are not included Chinese letters, with the exception of "Lunar" - which comes with K-Settings. Gratitude users know how to get rid of them. For all others:
1) Go to K-Settings, in there to:
2) Notification Settings / Show "statusbar lunar" - deselect.
3) Go to Lockscreen and desktop settings "Lunar calender + desktop wheather lunar" - deselect."
Great work, flashed it on my UL00 3 hours ago after wiping cache and dalvik cache only, everything seems to work alright, I can confirm that this ROM works flawlessly on UL00.

Hi Thank you for your feedback!
You have installed the ROM on the Middle Eastern variant UL00C185...
I am glad to hear that it not only works on GRA-L09
This is what I promised, but I wasn't 100% sure - cause I have only L09...
I am interested which build number is displayed in "About the phone"?
Thanks!
Everything is looking good so far. Thank you for your time and effort!
How do I activate automatic call recording? Is there a possibility of adding more regions to this rom? I have region specific software that fails. My digital satellite provider's software checks my region before it can work. I'm in South Africa.

Hi there Automatic Call Recording can be enabled that way:
Open the Dialer App - below left is a star, below right is the symbol for the settings menu. Open it and there you can enable automatic call recording.
For the other issue: Can you give me a link to an African Marshmallow Huawei Stock Firmware? So I can look at it and perhaps include the Region.
Which Region did you set up right now?
Thanks very much man!
Flashed it last night, after it took me half an eternity to backup all my files (had something messed up so I had to look a bit deeper). Flashing and all was fine, including xposed via magisk.
Been using it the day now, but at 2 Things im not sure if it is caused by the Rom or by the latest whatapp update:
-in widgets i can select WhatsApp - but there is no more this huge 4*2 widget with message-preview, does anybody else have this? (only WhatsApp Chat and WhatsApp camera available there)
-even though i have given WhatsApp all permissions, my Screen won't wake up when i receive a message. It was quite usefull while the phone lay at my table i could see in one glance whether or not it was important and decide to pick it up
....okay i have tried a bit and found out my Screen also won't wake up after receiving sms or email.. where could i look after that? every app has "Show on lockscreen" enabled
There was another thing, which i could't read fast enough, but it was something with kvip Settings and some overlay permissions and a path where to find them or so?
it popped up a couple of times at the beginning (those little messages in the lower middle of the Screen, just like "wifi connected") next time i will try to make a screenshot of that.
edit:
@Tecalote congrats for 500 Posts and 300 likes! :good:
@Tecalote your ROM IS ****ing awesome, congratulations!!!
Enviado desde mi HUAWEI GRA-L09 mediante Tapatalk
@ChavezD For the Wakeup Screen you must open Phonemanager and in there the Notification Manager. Every App like WhatsApp and Gmail, Email... is in the list - open WhatsApp or Email in the list and set up "Showing on Homescreen" and everything.
The other things I must look. Small popup messages should be shown, like "RAM 1.7 GB available, Wifi connected".. I must look later, at the moment I am not at home
Edit:
For enabling the Wakeup on Homescreen - you must go to Settings /Screenlock and Password - and there set up : Notification turn on screen!

@Tecalote yeah those Settings are all activated, really don't know what went wrong for me again or what i broke..
EDIT: OH god damn it, thank you so much! I hope i didn't actually disable it half sleeping this morning/"night"
Take your time, it wasn't annoying or anything, just wondered what it was. But it's exactly as you described, but not just 4 words but 4 rows or so in the same time period.
Maybe im also gonna reflash and not install every stupid app i've installed once. Is there any Chance to stop Google from automatically downloading all (>100) recently installed apps after reflashing a Rom? [I always Flash clean, so.. no dirty Flash for me^^]
Edit2: I think in those Messages i was talking about it wasn't Overlay - it was Dropzone. But still no clue what i should do there, everthing is allowed that wants to be

Hi again You can stop Google from downloading the previous installed Apps at the first start. After Google Login you will be asked if you want to restore - just deny.
Don't know yet what you exactly mean with 4 rows in the same time.
Do you mean perhaps Toast Messages? There's for example an Xposed Modul called "Perfect Color Bar" - in this you can enable "Toast" with mixed compatibility. After you get instead of the the small black info messages colored ones with the symbol of the App message. There are also other "bars" on the Repo for customization that messages.
Do you remember which official firmware did you have before using Custom Roms like Gratitude? b317, b321a, or b370? I know, there were some modem updates coming with the official firmwares (which cannot be done with Roms on Huawei Phones)
Maybe you should update to officially Firmware as an step between before reflashing the Rom. For this you would need the Stock Recovery, which can flashed from K-Settings, more Settings. On xda you can find the b391 here:
https://forum.xda-developers.com/huawei-p8/how-to/firmware-huawei-p8-b391-gra-l09c432-gra-t3534020
It would refresh the Rest of your Phone (which cannot be reached by ROM) - and after the ROM can work as it should...
Just an idea

Camera ? not working

After update b390,, ever thing is OK ?, and work perfectly..
But camera ? not working, please help.

Guide to succesfully downgrade from 9.1 to 8.0.0.386 (C432 = European Phone)

Hello everyone,
This is the procedure that I followed to rollback my EUROPEAN P10 plus from Emui 9.1 to 8.
Phone was Unrooted + Locked bootloader on 9.1
As this implies downloading territory specific firmwares, I can only provide information on where I found specific ones. Unfortunately, I have no Idea where to find 9.0.* firmwares for other geographical locations.
1. go to https://androidhost.ru/29XI and download the 9.0.* firmware hosted there. There might be a bit to fiddle if you have adblockers on.
2. At the end of the download, there should be a file named: Huawei P10 Plus VKY-L09 hw eu HLRCF Vicky-L09B 9.0.1.163(C432E4R1P9T8) Firmware 9.0.0 r3 EMUI9.0.1 05014KJP [androidhost.ru].zip
3. The zip archive should be around 4.6 GB in size
4. Decompress it with your favorite utility (7z, Winrar, etc.)
5. Now there should be 2 folders: "ReleaseDoc" and "Software"
6. Inside "Software" there is the "dload" folder.
7. Inside "dload" you will find 2 folders and one file (see screenshot)
8. Delete the folder "VKY-L29_hw_eu"
9. Copy the dload folder in the root of your SD card
10. As a matter of precaution do a factory reset followed by switching the phone completely off
11. Press Vol-up + Vol-down + Power button and keep them pressed
12. The automatic update from SD card should start. Let it complete
13. Once completed, you will have to go through the initial phone setup
14. Once Phone setup is complete plug the phone to the computer, select USB to transmit data and launch HiSuite
15. I used HiSuite version 9.0.2.301
16. Give again all of the authorisations for HDB and wait for the connection with the phone to establish.
17. Start the update procedure, but when prompted select to use the other option.
18. The rollback description will display. Launch it and keep the phone connected. It will take a while.
19. The phone will automatically restart and install Oreo.
20. You are done

It should.
However, in this case at point 9 of the procedure I described, the folder "VKY-L29_hw_eu" should be kept and instead the folder "VKY-L09_hw_eu" should be deleted.
Thanks it works,latest version hisuite its not necessary the version you said,the latest works fine to downgrade(tested by me).
Thanks million, It Worked 1st time on my VKY L29
I did follow the OP and use HiSuite version 9.0.2.301
Hello. Do you have some links po P10 dual sim? I want to bo gack go 8
What are the main reasons to go back to Oreo? I just got a Huawei P10 Plus, love the exterior design of this phone, it has android 9 installed, wish it had a dark theme and smaller fonts
Man you are the best!!! Thank you very much. I follow the steps and now i can go back to older version. Thank you again.
If you know how to rollback to android 7 plz post it.
Thank YOU!!!!
So I've been struggling for months now and was seriously considering not liking Huawei anymore & trashing it. But then this gem of a post came along. Worked perfectly first time:good:. I have a rebranded VKY-L29 that was using EU software and had 9.1 on.
Will this unlock mt VKY-L09 running 9.1.0.252 I just want all the Hauwei crap off and a stripped ROM. It's a great phone but slowly being ruined
Can anyone share the file ? It's saying 7 days to download

Actually. don't worry. I'm going to buy a OnePus 6T

[NOT WORKING FOR NOW] How-to OTA update without loosing Root - Stuck in "Preparing system update"

Google has changed the way they push and apply OTA updates via GMS, and thus making Magisk Manager's "Install to Inactive Slot" feature bootlooping Pixels. I think I'll hide this option temporarily in the next release before I have time to figure it out (topjohwu)

[Guide] How-to OTA update without loosing Root - Stuck in "Preparing system update"
Hello All, here is a quick guite to avoid getting stuck in "Preparing system update", if you forget to disable automatic system updates you will need to sideload...
The difference between this guide and others is to restore boot images BEFORE checking for updates
1. Make sure automatic system updates are disabled - THIS IS A MUST
Open Settings -> System -> Developer options
Disable 'Automatic system updates'
2. Open to Magisk
Click on UNINSTALL in the bottom
Click on RESTORE IMAGES (You will see Restoration done!)
Once done, DO NOT reboot
3. Now search for System Updates
Go to Settings -> System -> System update
Press 'Download and Install'
Once done, DO NOT reboot
4. Open to Magisk
Click on INSTALL button (for 'Magisk is up-to-date' option)
Press 'Install' again (in the popup)
Press 'Install To Inactive Slot (After OTA)'
Once done, reboot
Please keep in mind that if google detects Magisk (you will get stuck in preparing system update and then no updates will be found), you will need to sideload ota, and re-root your device, to use this guide.
This works on pixel 3, pixel 3XL. pixel 4XL as well
Awesome, I did not know that restoring images would make OTA updates show up!
