Thanks for your feedback and for your engagement to find and explain a good solution - which is very helpful for Users who have perhaps the same problem :)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Oberon84:
Dear tecalote, maybe you could help me. After 2 weeks of usage of your excelent Rom I have a problem. I've installed your Rom from 399 build of Huawei android. And now, suddenly, a have lost 2g/3g signal posibility. My phone uses only 4g and since my operator dont have VoLte supported infrastructure I only can use sms and internet but unavailable for calls. Dont know does anyone expirienced that problem? If you know something, please help. Thx in advance, even if you cant help me thx for such a good Rom :D
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
What's the official model you have?

ULxx or L09 and what was the last official Firmware you had installed before using Custom Roms /M.Arrow?

And which cust was shipped with your phone?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Oberon84:
I have L09 model. Last official firmware was 399. Dont know which version of cust or how to check it. Is that 432 maybe in full name of my model?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
If you living in Europe your cust should be c432 and if you were on latest Firmware before it should also be okay - so I have no idea yet why you loose this signal - have you tried to change in phone settings /mobile network to change the network from 4G to 3G/2G?

I will look into this issue tomorrow
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Oberon84:
Yes my Cust is C432. I've tried to select only 2g/3g auto and then I loose signal totaly :( Thx for your help. I apreciate it. If you could find any solution that would be great.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Quick question: how can we disable the high volume notification? "Raise volume above the safe level?" I looked for it in K settings but I couldn't find it.

If an Xposed module is needed for this, which one?

Thanks
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Oberon84:
I think its conected with settings for Viper drivers and Dolby Atmos. Turn off specific settings there and you will lower the sound for notifications. Hope this help.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Thanks, but I'm not sure if I understand: I wan't to disable that "feature" completely. (I know it can be done (e.g. on S5) what I don't know what's the proper way to do it on this ROM.)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Oberon84:
You have Dolby Atmos driver. There turn off that and see if your notification volume go lower. For me that do the job done for high pitch notification tone.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Reinstalling the Rom will fix the problem, without loosing apps, data or settings.

Make sure you use in TWRP Wipe - but then NOT Factoryreset - click on the Advanced Wipe

In this area enable:

Dalvik/Art Cache

Cache

cust

system

(not data!)

Swype to confirm - after flash Rom again.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Errr... :) I don't find it in Viper4Android FX: neither in the settings nor in the main module list. (I only use the Viper Bass module.)

There's only a "Uninstall Driver" option in the left side menu. But I don't know what happens if I uninstall it.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Oberon84:
Dolby Atmos is a different app or icon, whatever you call it, in your drawer. Find it and turn it off.

Hi [MENTION=6870018]Tecalote[/MENTION],

I've installed this ROM (my previous ROM was MagicArrow-v2, I think you remember me) and I've installed the Magisk edition with the factory reset (I've followed exactly all the instruction you wrote)

I've a "problem", I don't know if I'm the only one, but if I turn on 4G/3G/2G the phone reboots itself 2-3 times, after the reboots the phone starts work correctly for like 30-40mins, then reboots again...

The phone does the same thing when I switch to 2G/4G to 2G only and if I don't use the phone.

If I use the WiFi connection or if I enable the airplane mode, the phone works correctly.

Do you know why?

Thanks for the great work and this great release!
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Thanks for your feedback - indeed some Users face this problem and slowly I get an idea why.

You should do this steps (some post before yours:

https://xdaforums.com/showpost.php?p=75793474&postcount=86
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] davideakc:
Do I need to flash again the ROM even if that isn't the same problem? I don't lose the signal...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I would do!

The important step is not to flash the Rom, but to wipe (with advanced wipe) the cust before flashing with TWRP.

And sure, once it is wiped - Rom must be flashed, because nothing will work without the cust..

It seems the script doesn't wipe properly cust and that's why some parts of the old cust from previous Rom makes conflict with current Rom.

I have not changed anything in original cust, which is shipped with the Rom. That's why this is the only explanation why some Users facing similar problems.

In some weeks I will update the Rom with newest Magisk and with a changed updater-script to wipe cust properly.

Perhaps I make before a Patch zip, which do same job - to wipe properly cust and reinstall it.

But at the moment I have no time cause my job.

I will do soon I get a window to do it.

In the meantime you can reflash Rom - but it makes no sense if you don't wipe cust before with Advanced Wipe
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] davideakc:
Ok, I've followed the guide you linked in your previous answer and the problem

seems

fixed

(I've tried to change 4G/3G/2G connection and other stuff and the phone has worked correctly without reboots)

Thanks like always! :)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] beardedwonder:
Could this explain why I get this vendor info from *#*#2846579#*#*:

My phone is a UK Gra-l09.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Yes!

So do the steps (exactly) please and it will solve your issue.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Thanks, I just checked, I also have this :( Note that I went through the german tutorial.

So I'll have to do those new steps as well.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Yes, sorry - but it's not much work - if you don't wipe data you loose nothing (every setting, every installed app will stay)

But it's necessary to wipe cust (and Dalvik Art Cache, Cache and system - but not data) and then reflash Rom.

I will update this Rom during next weeks
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] beardedwonder:
Same issue after performing the wipes and reinstalling, it doesn't seem to affect the performance of the phone, although I wonder if this is why I no longer have the 2g only option.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
You did the steps and have no 2G only?

In this case a Update of the Background Firmware would be required. But this is some more work, because in this case you would must go back to Stock Firmware, Update Firmware and then doing all steps again...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] beardedwonder:
The 2G only option is not there. Which firmware should I go back to?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Tell me once again your phone model (GRA-?)

And your cust.. I can't remember, cause of much posts in different Forums and I don't want to search yet, thanks
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
No worries at all, I just wanted you to know :)

I don't have it either under: Settings- > More -> Mobile Networks -> Preferred network mobile

Only these are available:

- 4G/3G/2G/auto

- 3G/2G auto

- 3G

And I went through the whole process (flashing the stock b399, etc.). Phone is European model (c432).
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
And you wiped cust (+Dalvik Art Cache, Cache, system) with Advanced Wipe (not Factoryreset) before flashing Rom?

ART Optimization module

Dear Tecalote, does ART optimization module v2.0 by veez21 work on this ROM?

L09 C432

Same here. I went for clean install of 399, then this ROM (I had that TWRP flashing issue [needed to re-unlock bootloader].)

I Advanced wiped what you said and then reinstalled the ROM this morning.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Okay, thanks for letting me know.

I don't face this problem on my phone, that's why I'm thinking know it could have something to do with the Magisk Update..

However - I will update this Rom during the next weeks to v4 (solving this problem hopefully) with newest Magisk and newer Release of Busybox and other small updates :)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Yes, I had to select them manually.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] beardedwonder:
I only use the supersu version.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
That's good to know, so maybe it is only an issue of SuperSU-Edition
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Sparkrite:
Just to let you know I'm using the SU version on a L09/Cust432 and have no problems whatsoever.

[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Thanks and sorry for the late reply: it worked for me as well! I didn't even know (haven't realised it) that it's on by default.

I just played with the setting and I don't like the effect, so I turned it off. (Headset DTS is still turned on in Audio settings.)

GRA-L09, c432.

And to be more confusing, I'm using the Magisk edition (updated to v16 as per instructions). :)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] beardedwonder:
Oh well!

I think I will wait for the next update and do an install from scratch including a factory reset in the stock firmware.

My GF got a P8 which has become slow and is unable to utilize SD-card. I'm thinking upgrading her P8 with MagicArrow. Does MagicArrow make it possible to store apps to SD-card? Also, which version should I choose - which is most stable, this v.3 or the last version?

Btw, thanks for great work!
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Storing Apps on SD with Apps like Link2SD is in Android 6 only supported with native method.

But you can use also settings /apps/name of app - some apps can moved to SD.

But I don't recommend.

Apps doesn't take much place from internal memory.

Most place take media folder on internal storage (example WhatsApp folder with videos..)

First step I would do is to clean up the phone.

Backup from folder from internal storage on PC

I would eject SD Card, copy the files into folder on PC.

Then format SD Card with exFAT (best).

Or buying new SD if old one is perhaps damaged.

Phone must recognize SD or any system would not work properly.

Then I would make a backup with Huawei Backup to external SD (including installed apps but without system apps like Phonemanager)

After I would first update the Firmware on P8 depending to model /cust (it's important to know which model it is - settings /about phone build number)

I would make Factoryreset with wipe of internal storage from settings /advanced settings /backup restore /data Factoryreset /wipe of internal storage

Wait for the new release, or flash MA v3 with the installation Guide from OP.

Restore Huawei Backup
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I will look into this issues and fix it with next release
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Users of Magisk Edition - don't use Beta Update Channel in Magisk Manager.

Don't update Magisk to v16.1. I will provide a flashable zip during next days for updating Magisk.

All you can do is to update Manager itself - if you receive notification for installing Magisk Manager apk.

But don't update Magisk yet!
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Thanks for the info, I just disabled the update notification of it. And I will wait for the full ROM instead.

Hi! I have installed in my P8 the previous version b398 of this rom precisely the classic edition. Have I to unroot my rom before to install the new version b339 supersu edition? What I should do if I want to install magisk edition b399?

Thanks a lot
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
You must Unroot (see steps in OP) and then wipe (Advanced Wipe) Dalvik Art Cache, Cache, cust, system and after flashing Rom.

If you don't wipe data - your apps and settings should stay
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Robergo:
Ok. After I have unrooted the current rom and madre the necessari wipes can I install the magisk or superai rom version indifferently?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
You can install Magisk Edition if you like (both is possible)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Sparkrite:
[MENTION=6870018]Tecalote[/MENTION] has taken the time to make this ROM ( a lot of time) and has also taken the time to give FULL instructions in the OP of this thread, why don't you give some of your time and read what he has written in that post.

It really would help you.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Robergo:
You are right [MENTION=5658496]Sparkrite[/MENTION]. I read the instructions but I didn't understand them because with the previous versions It was not necessary to unroot the phone
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I made a fix for this issue and I guess it's an issue of TWRP.

During wipe data the information get lost cause it's not excluded from data wipe.

I will report it to the developer of this TWRP.

During next days I upload the fix (it's for all which live in Europe)

Widget size bug

Hi, after installing the ROM I can't use Widgets because the size of each is said to be 2147483648x2147483648 (I can't upload the photo because of the 10 post limit). Have you got any idea what is the problem and how to solve it? ROM is fantastic, but lack f widgets is unnecessary limitation :(
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Which P8 to you have GRA-xxx,

what was your Firmware (build number) or Custom Rom (previous MAv2 or CM..) before you have installed this Rom,

did you flash clean or without wipe anything?

I don't understand exactly what you mean with limitation of widgets size

Please post more information about your phone and the issue, thanks
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Rupietek:
That was my firmware: GRA-C900B321,

I flashed clean, wiping everything.

[IMG="Preview of the problem"]https://i.imgur.com/WCR5149.png[/IMG]

(at the bottom of the screen, you see the widget size and the error after clicking 'no space left').
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Okay:

1) Your Background Firmware is too old b321 is about two years ago - that means your Stock Firmware should be updated first to b370 (with automatically closing Bootloader - must after reopened again) - after updated to minimum b398, better b399.

2) A Factoryreset with wipe of the internal storage (on Stock, with official methods is required between and before flashing TWRP again to install this ROM)

3) If you had c900 in your build number (normally should be c432 or other cust) - could it be, that your phone had a branding before you flashed b321? Maybe Vodafone or Telekom Branding? Phone should be debranded first, before flashing b370 (can only be done on Adroid 5 with downgrade and the required steps)

Have you tried to place the widget on a blank site of the Homescreen (without any other app symbols) does it work or is it the same?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Rupietek:
Ok, so I will proceed with 1-3 steps and reinstall the ROM, thank you for the advice.

I tried with a blank home screen - unfortunately, the result is the same. I'll let you know if the problem is back after doing 1-3 steps.

[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] mbenjij:
Thanks. I have installed it and working. The problem is the cts fail. I upgraded from MagicArrow v2.

This is my phone:

FROM

Model Number: HUAWEI GRA-UL00

Build number: GRA-UL00C185B398

TO

Model Number: GRACE

Build number: GRA-MagicArrow-3

I followed this advice:

Magisk v16 Update available - do it with this steps: https://xdaforums.com/sho...3&postcount=22

Please assist with a solution to resolve issue in cts.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Questions: 1) Is only CtsProfile false or also basicIntegrity false?

2) Have you enabled AdAway host file (in earlier versions it was necessary to enable systemless hosts in settings of Magisk Manager - but with new Magisk it is not anymore required and systemless hosts must be disabled in Magisk Manager)

Necessary is also: don't modify anything in /system.

If you add or delete something in /system safetynet will fail and you must reinstall the Rom.

If safetynet test fails with other reasons you can try following:

1) Make sure systemless hosts are not enabled in settings of Magisk Manager, if enabled then disable it.

2) Enable Developer Options in settings and in there enable USB Debugging

3) Open Playstore and disable in menu PlayProtect

4) Reboot phone and check again.

5)If safetynet fails again - set your phone into the Flight Mode

6) SET YOUR PHONE INTO FLIGHT-MODE!

7) Open native settings /apps and (right down) more: Show system processes - click on every following app and delete in storage-section: cache and data (some of them show you: manage space - in this case use "Delete all data"):

Google App

Google Play services for Instant Apps

Google Playstore

Google Play-Services

Google Services Framework

Huawei ID or Huawei Mobile Services (which is the same)

8) Reboot your Phone

9) If you get a message after Restart "Your backup-account is not set yet" - DONT enable it now!

10) DISABLE FLIGHT-MODE NOW - and wait until you have full network-access (open Browser for testing)

11) Now you can enable your backup-account (message is shown in statusbar)

12) Open Playstore - If you are facing a problem when you open Playstore (showing just a blank site) - open Settings /Apps /Playstore /storage - but this time wipe only Cache inside, after Reboot your Phone.

13) Check safetynet again. If Magisk Manager switches away, go to settings /app/Magisk Manager and delete only cache (not data)

14) If safetynet fails again - Check Magisk Hide in Magisk Manager:

Following Apps should be enabled in Magisk Hide (if listed):

Android System Web View

Chrome

com.android.cts.ctsshim

com.android.cts.priv.ctsshim

com.huawei.hidisk (Huawei Filemanager)

Google

Google Play Store

com.huawei.hwid (Huawei Mobile Services = Huawei-ID)

NFC-Service

15) If not enabled, enable these apps in Magisk Hide and reboot phone - hopefully working after all those steps.

If Themes don't work there's a workaround.

In HWThemes folder is a hidden folder named .cache

Just deleting this folder and rebooting the device solve the problem (mostly)

Only if Theme manager (Design App) doesn't work properly there are other reasons.

Hi there!

I have come from fRomFuture - Gratitude V3 rom and followed the instructions for a clean install (in addition to backing up some app data using titanium backup to restore later).

All went well until the first reboot (i think) from within the rom where I seem to have lost root access suddenlt.. I no longer get superSU prompt when apps request root access. and also booting up takes really long.. like as long as the first time boot up... easily 8-10 minutes (although i haven't timed it it's been over 5 minutes for sure)

I've tried re-rooting by unrooting and rooting following this guide (https://xdaforums.com/showpost.php?p=75460388&postcount=323) I basically did this:

in TWRP

1. flash unSU

2. Restore stock boot.

3. Flash supersu

4. Reboot

However this has not resolved the issue. SuperSU is not prompting me for app access.

FYI, in bootloader screen i get "PHONE unlocked".

Any help on how i can get root back ( and maybe to a lesser priority the boot up times)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] 1ted55:
Hello

I have to say that I am taking back

I installed this ROM again

For the problem I mentioned earlier, I restarted my phone and went into recovery and removed the theme folder from the internal memory and the problem was resolved.

Thanks for this rom
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
The folder .cache is hidden on internal storage in HWThemes.

It is hidden, so you can't see.

But if you open Huawei Filemanager (Mixplorer can also enable "show hidden") and the inside settings you can enable "show hidden folder" Then you are able to delete .cache in HWThemes.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
If you are coming from Gratitude v3, it is required to go back to Stock Firmware first and update the firmware to latest v which is available for your device.

The problem is because your background Firmware is too old.

Custom Rom doesn't update your Firmware, it's just based on a firmware and the Firmware in the background should match (as far as possible)

After do steps from OP and flash the Rom.

The Rom comes with working Root, you don't need re root.
