Hello :) Did you let the original GApps from the Rom, or did you flash another GApps? I ask, because we never had this problem before...

You can try following:

1) Go to Settings, Apps, right down click on menu - show system processing. In the list search for Google Play Services and Google Services Framework, Google Playstore, Gmail - go inside the Apps to Memory and delete data and Cache in those Apps.

Do this with every Google App (Google Account Manager, Google Backup Transport...)

2) Go to Advanced Settings to date and time and set a wrong time (example: instead of today 6: pm set yesterday 6:pm)

3) Be sure, you have not activated in K-Settings, More settings, Block Ad (this blocks Google Services) - for blocking Ads use AdAway!

4) Delete your Google Account one time more

5) Reboot your phone

6) Go to Advanced Settings, Time and date and correct the time to the right one.

7) Set up your Google Account - now everything should work

Thank you a lot for your help and your great job. The problem still exists, I am using Rom's gapps, i will flash another one time the rom and I will let you know. Thank you very much.:laugh:
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
You can try another two things - go to TWRP and make Advanced Wipe of Dalvik and Cache (only), Restart needs about 10 min.

And try to Login to your Google Account on PC, just to see, if it is possible or if there are some Security Issues..

When I install a new Rom (makes a new Android ID) or change the SIM, or get another phone and Login with same Account I receive a Notification from Google - if I don't answer, Google may block my Login on another device /Rom...

Thank you very much for your donation I received in the evening :)

Hi,

I'm on New Word v4 now, do I need to flash stock rom first or can I flash v7 right now with twrp?
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Hi :) You cannot flash - Fingerprint would not work anymore...

I wrote everything in OP:

https://xdaforums.com/p9/development/rom-huawei-p9-newworld-7-tecalote-t3543296

You must go back to the latest MM official Firmware (Factory Reset and closed Bootloader - must after Upgrading reopened!)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] frederikd:
Thanks for the info!

Think I'm sticking with v4 now, awsome ROM!

Battery life is just crazy good, and after converting apps like whatsapp, Facebook and instagram, the push notification problem (Huawei's fault with the excessieve battery saving software) was solved.

I read that you are working on a v8 with Nougat support? Think I'm going to wait that one out ?

Anyways, keep up the good work!
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Hi :) Yes I will finally also release a good Rom for Android 7 - but at the moment I wait until TWRP get his full functionality.

It doesn't Support data encryption yet - so you can't backup your data with TWRP (only the system)

Android 7 is much more complicated to modify (cause it is no longer desired from Google and the Manufacturer like Huawei)

Also the way to restore Firmware (important for some cases) is very complicated at the moment.

Xposed Framework is not ready for 7.0...

It will take another while until my Rom for N is ready

Hello :) Welcome to my Thread - everything should be fine, there are no known bugs, except connecting Smart Watches.

If you make a Nandroid Backup, please restart the Recovery before making wipes and flashing the Rom.

TWRP has one known issue (unmount and remount Partitions after one action like Backup).

In expected one or two month I will release a ROM with K-Settings based on the latest Marshmallow Firmware b182.

First time based on European Firmware :)

Which System is your current (Stock or Custom Rom /which version)?

However, cannot flash Stock Recovery now anymore, and dload method doesn't work

Please help
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I see I must make a manual how to go back to Stock FW

Hi :) For all users who don't know how to go back to Stock Firmware I make a manual soon.

In your case you have to do following:

1) Connect your Device with USB to PC. Press Vol- and Power Button at the same time until Phone reboot into Bootloader Mode.

2) Open Minimal ADB and Fastboot with administrative Rights.

Stock Recovery must placed in the folder of the program directory of Minimal ADB and Fastboot.

Download:

https://www.androidfilehost.com/?fid=457095661767103492

3) rename Stock Recovery to RECOVERY (=RECOVERY.IMG)

Code: fastboot devices (you must see your SN + device)

Code: fastboot flash recovery RECOVERY.IMG

4) Disconnect USB cable and with Vol+ and Vol- and Power Button at the same time (pressing until EMUI Software Installing begins.

Alternative (before unsure doing this steps) you can flash with TWRP NewWorld again and wait for my detailed manual (tomorrow)

any thoughts how to solve?

Correction: I seems to work now. package ist at 37% already
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Do you have already Stock Recovery installed (cause whitout it is not possible to install Firmware!) Which Firmware to you use? You cannot go from NewWorld to Nougat, you must go back to Marshmallow first.

If you tried to install Nougat FW we have a big problem now, cause then you would have Nougat Bootloader.

In this case you would must use b300 Downgrade Firmware.

Have you seen Post 90?

This work only if you tried to install MM Firmware
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] juupke76:
I have seen post 90. It works now. Back to MM stock

it seems i've lost that screen.. my phone stucks at "Your Device is Booting Now..." ..

i can access the recovery, and the OS, but that recovery screen where the phone loads the update.app file, doesnt show..

what can i do?
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
The splash screen with "your device cannot be trusted... and is booting now goes away if the Bootloader is closed. Updating with Stock Firmware always close the Bootloader on P9.

If you can enter Stock Recovery wipe Cache with it and make a factory Reset.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
[MENTION=5539557]Blackmedicine[/MENTION] You can boot into system? Which system - NewWorld or Stock Marshmallow?

If you are on NewWorld you must flash Recovery from K-Settings /more settings /flash recovery - flash official recovery. The Firmware must unzipped on PC and copied to a folder called dload on your Phone (only update.app and meta.inf (if present) - nothing else should be in this folder) And you can start the update to Stock Firmware with 3 Button method. But at first, Stock Recovery must be flashed.

One advice to you all : freeze Phone Manager application. The result will be a free phone , you will not need to convert whatsup and others to system app etc.... Everything will work perfectly , as it should, also there will be no battery drain at all. I am using the phone without it and it works awsome.... No missed notification etc.....

Just try it before posting some negative opinion here...
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Thank you very much for this useful discovery Sir!

That means also Phonemanager is not working as it should.. .

It's a good solution you find, I will anyway look what's happening with Phonemanager

Thanks :)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] kye04:
Phonemanager is build to take control over the apps. From there you can manage the permissions you give tot the apps, also he closes the apps you do not want etc.... The problem is that it is not working correctly , this is why many normal users complain the notifications from whattsup or messenger do not arrive unless you wake up the phone....

System apps are basically imune to the Phone Manager app ..... Also the phone comsumes more power with Phone Manager because the apps wake up, the Pgone Manager closes it and so on..... It is like the old Task Managers on android before 4.x , people beleave it was helping but actually it is draining power....

I am using it like this for more then 2 months and it is perfect.

Beware : do not unisntall it !!! Jest freeze it !

Also 2 other tricks for battery help : put display resolution to 720p and dpi to 300 or 320 from k settings.... You will be amazed how much battery u`ll save...
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Blackmedicine:
How do you freeze it? With an app?

Cause I can force close it but it will always restart in background
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] kye04:
I use link2sd . From there you can freeze it. There are alot of other apps, inclusing titanium backup....

Does anybody has problem with GPS, and Uber app?

On my phone, everytime I open Gmaps, the GPS starts running and takes long time to detect location. in Uber app, I cannot make booking although I gave all permission to Uber. It works well on another phone (same account).
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Which EVA model to you have?

I activate GPS before starting Apps which use GPS and for me it works without problems.

Uber maybe uses safetynet check now and perhaps that's why booking don't work.

Is your other phone rooted?
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] swedenboy:
I use your ROM on AL10. THe other phone is unjailbroken iPhone.

But I use Uber before on my rooted HTC butterfly 2 and It worked well.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
The iPhone is not jailbreaked, right?

I saw that lot of apps which booking or paying function don't work since those apps uses now safetynet check.

I cannot buy stickers on Viber and cannot book a flight with Opodo app on my phone.

Before (half year) it was possible on the same phone, also rooted. This occurs cause more apps using safetynet check now.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] swedenboy:
another issues is with GPS, google map cannot detect it, uber and android device manager have same problem.

In the stock Nougatm, GPS has no issue like this, but, I cannot root my phone to freeze phone manager (as above instruction), and there is not full google framework that playstore cannot recognize my phone (using computer browser)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Okay, you were already on Nougat before. After you maked a Downgrade to Marshmallow and after you installed this Rom?

The GPS problem can be occurring because you were on Nougat before.

Many people report problems after Downgrade from Nougat to Marshmallow.

Normally GPS is working in this Rom. Nobody has problems with it reported.

I would go back to Stock Marshmallow and doing this with special steps.

Later when I am at home I can give you an instruction how to do this.

Then you must test if it works in Stock Marshmallow. If it works it will also work with this Rom and finally you can install this Rom again.

Or you wait some weeks, because I will release a new Rom based on European Firmware. (Marshmallow)

My Nougat Rom comes in some months.

TWRP for Nougat is now released with encryption support for data - but there is no save way yet going back from Nougat Custom Rom to Stock (because there's no flashable Full Firmware with dload method at the moment) and that's why I wait with the Nougat Release of this Rom.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] swedenboy:
Yes, I came back from N to MM via Hisuite. I'll restore Stocked MM and wait for your instruction. it would be greate if you could develop a new Rom base on EU version.

By the way, is it ok to debrand from AL10 to -19C636B168? I'm gonna do this to get rid of these issues from CN rom.

Thanks for your support.

Finally, I can debrand it to L19C636 without losing any storage or RAM :D. Thanks God for that, now it stays on L19C636B361 with no issues for viber and uber - a little bit slow due to GPS searching, but, It works and I'm happy.

thanks for you support, I keep waiting for rooting Nougat the try you rom later.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
Thanks for your reply :) Which Firmware for AL10 exactly did you use for going back from NewWorld to Stock. Can you post the Link please.

And how did you debrand - have you used SRK Tool?

I am interested how you did it and perhaps other users
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] swedenboy:
It's quite easy to restore from NewWorld since I've made Nandroid backup before flashing your rom (and NewWorld ver 4); then I simply made restore using TWRP. however, I think another best way is to run eRecovery by pressing Vol - at boot screen.

I have a note here, since my friend have another AL10, which is produced in Jan 2017, therefore he has no way to get back to MM for debranding his device., running eRecovery still get him to the lastest version of Nougat. If anyone have idea to roll back MM for this type of device please let me know.

Secondly, my procedure for debranding using SRK tool is as follow, quite simple and not as much difficult as the video showing:

1. Unlock bootloader => install TWRP => root. (I have to manually flash SU 2.7.9 since the SRK tool does not recognize my device in the last step of rooting, however, it worked well)

2. Restart device, run SU# to grand permission for all pop-up items

3. Copy firmware to sdcard. I used L19C363B190 which is available for download via GG search, if you cannot find, I'll upload and share the link then. I used sdcard update method as per instruction in the last part of debranding video (running *#*#2846579#*#*)

4. Start debranding by using SRK Tool, select "Utility" (#7) and then "Change oem info and custom.bin" (#9). Choose P9 and then "asia LC19C636"

5. after that, device reboot with red message and it says input password for data decryption. enter any pass will make device restart in low level format. Don't worry, It will then boots to Os like normal, and you will see there was no brand in "about phone".

6. Perfom system update via sdcard.

7. Device boots up and again, saying input password for data decryption => enter any pass will make device restart in low level format.

8. After booting, your device will become L19C636B190, without loosing any RAM/storage.

9. Make the OTA to L19C636B361 if you want. However, since I use Nougat at first time with this device and then back to MM, I found that N is more better than MM :).

Note that after flashing C636B190, the bootloader will be relock, stock recovery will be installed so that you can make OTA update like a real L19 device.

dsp manager

can i flash DSP manger on? i see dolby somthing app but im used to have dsp from cm11 forward and used it on stock Huawei p9 ROM.

will it work?

i dont wanna corrupt or anything the files again.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] Tecalote:
I would recommend first test the integrated Sound Mod (Dolby/Atmos in combination with Viper4AndroidFX in K-Settings /more settings) its pretty good if it is setup right.

I haven't tested, if DSP Manager would work (probably not, but maybe) - make a Nandroid Backup (TWRP Backup with all shown Partitions), try it and if it doesn't work restore your Nandroid.

Let me know.

Edit: it's not faraway I release my new Rom based on European Marshmallow Firmware. I will make more Editions of the new Rom. One without Sound Mode. So User can experiment with own sound mods like DSP Manager or ARISE.

[MENTION=8125184]jure482[/MENTION] Did you read my previous post #117?

I read just right now:

Viper4Android FX is like the “advanced” version of DSP Manager/Beats Audio by providing you with more advanced Surround/Bass/Clarity/Gain boost controls in addition to an equalizer that you can use for your headphones, speakers, bluetooth devices, and more...

on following website:

http://highonandroid.com/android-apps/viper4android-app-for-rooted-android-best-audio-app/

And this is already integrated.

I can make a tutorial how to setup right Dolby/Atmos with Viper4AndroidFX. It makes a pretty good sound.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] jure482:
yeah i saw it later in phone, thanks. It looks good and there are plenty of options, think i"ll stick to viper4 fx.

it would be nice to get tutorial to set it up right since i use it for my car Hi-Fi system with new speakers installed last week and Blaupunkt San Diego 530 MM unit (no need for equalizer its on this MM unit)

[MENTION=8125184]jure482[/MENTION] Your question about MiXplorer is answered here: https://xdaforums.com/showpost.php?p=71388663&postcount=120

Your question about handling Dolby and Viper4AndroidFX:

Its easy. Just open Dolby/Atmos on homescreen. Above you can choose which mode (Movie, Music, Game, Voice and Custom) Below you can enable Surround Virtualizer, Dialogue Enhancer, Volume Leveler (Leveler is optional - just if you like it very loud).

Set up your preferred mode (for testing leave the App in Backgroud open)

Now open Viper4AndroidFX (K-Settings/more settings) - here you can enable and disable different settings (you must test, which one is good for you) - but even if you dont set up anything in Viper4AndroidFX, it will be processing in the backgroud.

Open BlackPlayer (it works very good with this sound mod - Stock Musicplayer support not all codecs) and play a song.

You can see in Dolby/Atmos and in Viper4AndroidFX (Driver Status) how it works and you hear the difference!
