Thanks, I used System app safe remover from Play Store for this (although Titanium backup could have been also used, but I wanted to remove it :) )

Questions regarding to removable system apps:

1. can you make your own additional apps (Titanium backup, Black player, etc) as systemless in your ROM? It would be easier to get rid of them if it's easy to implement.

2. can I get rid of the Phone Manager app (Huawei) completely? :)

(In S5 using 5.0 you could remove the very similar Samsung app)

Cheers
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Yes, I can implement apps also as User Apps.

But Phonemanager should not removed - if you don't like it, just freeze it (with Link2SD for example)

If you remove it, I don't make support for further problems with your installed Rom. I said, most of the Huawei Apps should stay on Board. Because they work in connection with other apps. Example : If you remove Huawei Recorder, Phone recording would not work anymore. If you remove Gallery, you cannot showing Photos from Camera App...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Awesome!

:) Understood!

Edit: Freezing is a good idea! I just did it, I'll see how it works in this way.

Please try attached zip (flashing with TWRP) - After flashing make Wipe of Dalvik and Cache (Reboot needs 15 min)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] tijsva:
Thanks Tecalote for providing the new flashable zip. Unfortunately, no difference at this moment :crying:

-Tried wiping cache + Dalvik after installation (also did that with the v1 release of this file)

-Manual searching for networks (still only shows China Unicom 2G)

-Resetting APN

-Swapping simcard to different slot

-Flashing the zip once more without cache + Dalvik

None of the above helped. Is there something else I can try?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I am thinking about it. I have a question - if you open Settings / More /Mobile Provider settings / Mobile network /Preferred Networkmode - what options are shown there?

Is it simular like Screenshot, can you change here maybe the network mode?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] tijsva:
Please find attached printscreens. Before I flashed your zip files I had 3 options, the shown two + 2G only. That last one is not there anymore after flashing the zip file.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
This is interesting for me...

Before flashing the zip files, you had one option more - but had you also the first one with 4G (shown in your Screenshot)

Okay, and if this is enabled now, why do you think you have no 4G (LTE)? I try to understand..
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] tijsva:
The menu's all allow me to enable 4G (see the provided printscreens), but the problem is that I can never actually connect to 4G when using a

China Unicom simcard

. 4G on the phone seems to work, I can plugin a China Mobile Sim and it shows 4G instantly. Problem is that my business phone provider is China Unicom, and then only E signal can be received. Seems to me that this is locked in some way...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
[MENTION=1995570]tijsva[/MENTION] ...okay, I understand. I found some interesting possibilities to solve it maybe. I will answer in the evening.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
[MENTION=6870018]Tecalote[/MENTION], I have a problem with both versions of the rom, sometimes during a call the phone reboots several times.

Probably the error came from an app? in that case, how can i identify this app?

Thank you for yor work!!!

In Gratitude this not hapend... I have xposed installed in both of them
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Hello :) This can occur if you have flashed GApps over the original Rom GApps - or from some Xposed Module like GravityBox or other - or from a third party App.

Which phone model to you have?

With Root Explorer go to /data/system/dropbox/ - send me all files from this folder.

In the meantime make a Advanced Wipe of Dalvik and Cache (no Factoryreset) Reboot needs 15 min.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
My phone is gra-l09 from Spain

I install the rom from full wipe, then restore from Huawei backup, i dont have gravitybox.

thanks
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Thanks for the log files, I look at it in the evening.

Note: Problem can also occur if you restored System Apps from Huawei Backup like Phonemanager...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
Ok! i try to restore without that.... and test it
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Okay, just restore User Apps, no System Apps or system settings from previous system!
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
Can I restore the home icons distribution?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Yes, Home icons are possible

[MENTION=6870018]Tecalote[/MENTION]: HD Skins for Poweramp don't work on 6.0, not just on your ROM but on any other Huawei ROM either. (More info: http://forum.powerampapp.com/index....-on-android-60-status-bar-skin-support-issue/)

What do you think: can you do something about it?

Cheers
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I found an article on a website:

http://www.china-mobile-phones.com/how-to-unlock-china-mobile.html

I would make the next zip file bringing you back the third Option in Network Modes.

Later I will make a General overhaul of cust. For this I take time, cause there are many possibilities to change things to be better.

Example: in Germany the Option for VoLTE isn't showing...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Yes, this problem is well known. But nobody found a solution for it. I also don't know why it doesn't work on Huawei Phones.

If the developer would make Skins by himself, they would work. But third party Skins are not working yet.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] tijsva:
Thanks Tecalote! I found the same link before and tried the app but does not seem to do much... Looking at the specs of the phone for China Unicom and China Mobile, this should be ok for both! I wonder if the imei of the phone is somehow known at China Unicom and blocked since it is originally a China Mobile phone... This would mean lots of work for the providers to keep track of so I doubt if this is the case...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] MagnaWoX:
Hi, please, how deactivate multiwindow mode. Thx
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Multiwindow Mode just opens if you press long on the square symbol on navigation bar.

Once it is open there's in the middle a turquoise field. Just klick on it and you get the symbol for closing.

On first initial start the symbols on home are maybe arranged chaotic. In this case just restart your phone. It don't come again.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] tijsva:
Hi Tecalote, I have done some further investigation. The following website shows the supported frequencies per phone, as well as the frequencies used for each provider.

For reference, EU model: L-09 frequencies: https://www.frequencycheck.com/models/O0ojr/huawei-p8-standard-edition-gra-l09-td-lte

My phone: TL-00 frequencies: https://www.frequencycheck.com/models/OyN1b/huawei-p8-standard-edition-gra-tl00-dual-sim-td-lte

China Unicom frequencies (my provider): https://www.frequencycheck.com/carriers/china-unicom-china

China Mobile frequencies (my phone is branded China Mobile): https://www.frequencycheck.com/carriers/china-mobile-china

Based on the above it seems that my phone can receive:

B3 (1800 +)	LTE (used by China Unicom)

B39 (TD 1900 +)	LTE (used by China Mobile)

B40 (TD 2300)	LTE (used by China Mobile)

B41 (TD 2500)	LTE (used by China Unicom + China Mobile)

Coverage wise it seems my phone should be able to receive the signal from both suppliers, it could only be software lock by the manufacturer supplier to only support China Mobile. This last however should be gone once I flashed your Arrow rom, correct?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
[MENTION=1153875]jbmir[/MENTION] Everything working now?

[MENTION=1995570]tijsva[/MENTION] I am not sure yet what's exactly the reason for having no LTE with China Unicom - but I have some more ideas how to solve it. It's not easy, but I try. I let you know.

[MENTION=4327948]00471[/MENTION] The Gallery enhancement Runtime is also an open issue. Same here, I have ideas to change this but it's not easy. Soon I find the right steps I do it and let you know
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] tijsva:
I will wait patiently :) Am I right that any restrictions in reception from the phone should be removed when flashing to a different rom (in this case yours)? Or are any signal unlocks done on branded phones also provider related?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
If your phone was branded from the Provider - example: You buy a phone with China Mobile Branding, but not SIM locked.

To have the full features of Firmware phone must debranded and have a clean Firmware without Branding.

Flashing Arrow needs a debranded Firmware base, it cannot debrand your phone.

Same here in Europe. If I bought a Phone with Vodafone Branding I must debrand it and flash after latest Marshmallow Firmware for the device. This base is needed for using the potential of Custom Rom like Arrow.

The steps for debrand are very different from provider to provider another steps are necessary.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] tijsva:
Alright, a colleague of mine used to have a China Mobile branded phone as well, and had the same issue with only receiving E signal. His solution was simply to enter a code in the dialer (*#*#5920*#*# or something), which after reboot gave him 4G support for China Unicom, which he did not have prior to doing so.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
No, it restarts again after a call, not always...

I wipe everything, reinstall user apps and data only from huawei backup...

What about my dropbox folder? do you find something?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
You must send me the folder once again - I opened it and there are only 0 byte Files in it.

You must make a folder in your external SD and then just copy the files from dropbox to the new folder and after zip it.

And may you can give me a list with all installed apps you have.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] 00471:
Thank you, really. Also, for people that are considering to install CM13, I tried it yesterday, everething was good but hell, camera quality was horrible, not by resolution but the lack of any software enhancement made it unusable, noisy as hell, low detail, taking photo against sun or any light source is useless, its unbelievable how much can do top-notched software assist.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
[MENTION=6870018]Tecalote[/MENTION], I have only 0 bytes files in root/data/system/dropbox
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Yes I heard about it, on this site is also a description with code: http://www.china-mobile-phones.com/how-to-unlock-china-mobile.html

And below its written it should may possible to get an unlock code from Huawei...

Anyway I think about it
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Which Root Explorer to you use? Name of the App?

There cannot be only 0 byte Files, may your explorer has not the right Root Rights...
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
Solid and Mix, both the same 0

Solved. 777 in roots
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Try to copy another text file with text inside to dropbox folder and see if it is there more than 0 byte. After delete it.

The text files in dropbox must like my attached file.

Which was the latest Firmware you had installed before flashing Gratitude and later Arrow?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
B392 or B393, I dont remember
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
If you can't send me log files, I can't see what's maybe happened. If the log files in this folder are really 0 byte something is really wrong with your system or configuration.

I must know which apps you have restored from the backup. (list) and I would like to have a list from all Apps you have installed.

It isn't a issue of the Rom, otherwise other people would also report.

It would have been good to test your Phone (calls) after fresh install before restoring the backup. It must be a conflict between another App.

And it is necessary to use the linked TWRP. If you made a TWRP Backup before flashing the Rom it was an important step to reboot TWRP before flashing the Rom. Don't know if you did?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] jbmir:
I want to do a fresh install without restoring apps, as you say.

Then if the error come back I send you de log files.

I totally agree with you!!

I use that TWRP and the restore is from Huawei backup only.

I tell you in a couple of days, thank you for all your support!!

May there's something helpful.

Maybe its conflict with Dolby /Viper?

Try to use it with not activated Dolby and Viper.

[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] 00471:
hello, any plans for B394 based version? :)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Hello :) Here is the changelog for b394:

This update adds new features to apps, including Email, Calendar, and Notepad, and optimizes the Themes icon.

Adds a feature to prioritize emails.

Adds more years to the perpetual calendar.

Adds Local calendar and Global holidays in Calendar.

Adds a feature to add and share contacts using QR code.

Adds a feature to share notes as text, image, or email in Notepad.

Optimizes email login by configuring parameters automatically.

Optimizes the Themes icon to be more consistent with the system.

Improved device security with Google security patches.

Maybe I make a new Rom based on this Firmware or I make an update.zip which includes the new features.

But at the moment I am working on Custom Rom for P9, so it will take a while.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] 00471:

Hello good I am currently suffering a problem with the light sensor and proximity of my cell phone. I have already tried to do a clean installation and the telephone is still the same, I'm afraid the problem may be hardware. Any suggestions other than taking it to the SAT?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Hello,

all you can try is, going back to Stock Firmware for your device.

Doing this is described here:

https://xdaforums.com/showpost.php?p=71149948&postcount=2

After you are on Stock Firmware you may receive an OTA Update (Phone must be clean without Root, no Busybox, no TWRP but Stock Recovery)

Test, if everything is okay with Stock Firmware. If yes, you can install Arrow again, if you like (problem isn't the fault of Arrow) or you stay on Stock FW.

If the problem occurs even on Stock FW,

it's a hardware malfunction...

Let me know!
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] koenster:
Hi,

I'm new to the Hauwei P8 and I bought a China Mobile branded device (GRA-TL00). Is it possible to install this ROM on the device without losing 4G support and other features?

I've searched but not found much.

Thank you!
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Normally China Mobile Net works with 4G using this Rom.

I would make a complete TWRP Backup of the branded Firmware with all shown Partitions (after unlocking Bootloader and flashing TWRP ) and also a Huawei Backup of all Apps.

After I would try this Rom.

If it doesn't work cause of branding issues, you can restore TWRP Backup and Huawei Backup of branded Firmware.

And if something missing you can flash Stock Recovery and Full branded Firmware for your Phone.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] nickromanus:
Hi everybody, is there any chance to install Pixel launcher on this rom? If possible, it would be nice to have a small guide to avoid problems.

Thanks
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Issue 1: the G keyboard became invisible after couple of days of usage. Reboot solved the problem.

Question 2: do you have any problem with live wallpapers? I use "weather now" (https://play.google.com/store/apps/details?id=com.hamsterbeat.wallpapers.fx.color.full&hl=en) and it crashes now and then (2 times per day at least), and I never had any problem with it on my previous mobiles (android v4.x, v5.x).

Thanks
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I haven't tested it in Classic Edition. I would make a TWRP Backup before (data, boot, system, cache)

Normally way is: Installing Launcher (Nova, or whatever) and then open Settings /Apps/Advanced/Standard Apps and in the first entry change the Launcher from Huawei to Pixel.

After reboot phone.

In Magisk Edition you can download and install Magisk Module Pixel Launcher.

Tell me how it works. Haven't time to test yet, cause I am in my job.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
1) Gboard should work without issues. I got no reports from other users.

You can do two things: Make a wipe of Dalvik Cache and Cache with TWRP /Advanced Wipe (no Factory Reset) - Reboot needs 15 min. Look also in Settings /Apps Gboard/Permissions if Gboard has relevant permissions.

If the problem comes again, install SwiftKey Keyboard from Playstore - uninstall Gboard (from system/app and from data/app/com.google.android.inputmethod.latin-1)

Reboot phone and reinstall Gboard with Playstore.

2) With Link2SD freeze HwWheaterClock and Widget (do not uninstall) - this is maybe conflicting with your Live Wallpaper.

Maybe it is also possible to setup your installed Live Wallpaper with Huawei Design App, Customize, Homescreen, Life Wallpaper.

Look also in Settings /Apps if this App has related permissions
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] chros69:
Thanks, Tecalote for the quick and detailed answers!

About 1: it just happened once, now it seems to be fine. I'll do the clearing cache if it will happen again. (Invisible means: you can't see the keys themselves (there's an empty space for the keyboard), but you can type with it! :) )

About 2: I'll try to freeze that app and see what will happens. It can also be a driver issue with the WheatherNow app. I'll report back.
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] nickromanus:

[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
You must go back to the Stock Firmware b391.

For this you must flash Stock Recovery.

After you have installed Stock Firmware (booted to system) you must install TWRP again and make a Fullwipe.

If you flash Arrow after, no more battery drain.

All steps in OP #2

clean flash encrypted phone?

so I finally went to update from Gratitude to Arrow (classic). Dirty-flashed, wiped cache, rebooted, it went through the optimization, everything looked fine. I went to poke around in k-settings, realized that xposed is not installed (is this normal? I thought that with a dirty flash it would be there?) Phone booted into TWRP, attempted to execute the install, rebooted, and got stuck on boot (swirly stars) screen for about 10 minutes. I forced it back into TWRP, and reflashed the ROM, hoping it might fix it, but after taking about 15 mins to reboot (swirly stars, no optimizations), it brought me back to Arrow, no xposed. I repeated the process another time, same results.

I suspect the fact that my phone is encrypted is at least a large part of the issue.

I'd really appreciate it if someone could point me to a resource or walk me through reformating the phone to get rid of encryption, because frankly, I just want to start from a clean slate. I tried Factory Reset from the Settings menu, it does not work, the phone reboots back with all the accounts and data untouched. There must be some nuclear option to blow it all up and start from scratch?

TIA!

Nikki
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
You must flash Xposed from K-Settings and wait until system reboots (can be first time 15 or more minutes, but system boot up for sure) Be patient, I wrote everything in OP
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] nikkiscores:
you are absolutely right, i was impatient, i did it another time, and forced myself to not look at the phone for half an hour, xposed now shows as installed. Woohoo!!!

Nevertheless, there are other issues, such as all of the apps that I had on the SD card are not showing up in the drawer (but are listed under Settings/Apps). Muzei's settings are not sticking, I suspect because it doesn't get loaded on startup. I just feel it is cleaner to start from scratch, but I can't because TWRP won't mount encrypted partitions to wipe them. What can I do?
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Encrypted Partitions are not supported, there's no TWRP with this function for P8

Backup all of internal storage, and go to advanced and format data partition to ext4, everything get wiped and may you loose TWRP and must install stock firmware b391 from dload (so keep it better unzipped in this folder)

I never did this, so I can't exactly say how it does on p8
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
[MENTION=7628871]nikkiscores[/MENTION] .... And Apps on external SD from previous Rom you can't use now because they loose during flashing the new Rom the Links to the system. Did you use Link2SD in previous Rom to move them to external SD? Let me know how you are doing with your issues (Apps and encryption)
[Huawei P8 ROMs, Kernels, Recoveries, & Other Devel] nikkiscores:
The apps magically reappeared after a couple of reboots and the phone sitting overnight. Weird, but who am I to question it! I had moved the apps via Settings>Apps>[Appname]>Storage>Change.

Everything appears to be working right now, so I am going to hold off blowing up the filesystem to get rid of encryption for now, especially since I just got a new tablet to play with.

Thanks for another quality ROM and awesome support, [MENTION=6870018]Tecalote[/MENTION], you da man!
