I've been unable to get google play to work the last few days, the app launches but theres never any updates even when i know there is,

whatsapp backup to google drive not working, essentially the google apps dont seem to be communicating with the internet.

Since then i signed out my google account and cleared data, tried logging back in then and it cant contact the google servers.

I've wiped Dalvik cache from the root explorer app, that didn't fix it, am i looking at wiping the whole phone?
[Huawei P9 Guides, News, & Discussion] daveh077:
Issue resolved thanks to zgfg.

QUOTE=zgfg]Have you tried:

-Airplane on

- For all GApps (System, Apps, Show System Processes), Delete Cache, Delete Data (some have only Delete Cache)

- Delete Google Play

- I would then also delete Dalwik again, boot to TWRP and delete Cache

- Then reboot, install Google Play, finally Airplane off[/QUOTE]

Hello, all I rebrand my Eva p9 it and install oreo thanks to you guys. Then I wanted to wipe the cache in twrp to try to fix the problem with Bluetooth. and because of that fools move to Make system unbootable. Is it now possible to start again at some point.

i was so proud until now :)

Thanks in advance Nenad

.
[Huawei P9 Guides, News, & Discussion] zgfg:
Wiping Cache in TWRP should not make Oreo unbootable (I wiped the Cache many times).

Maybe you wiped System or some other partition?

Can you boot again to TWRP, mount System and then check under Advanced, File Manager, do you still see files in System partition

Btw, just to double-check, are you using with Oreo the proper/corresponding P9-EVA-8.0.0-TWRP-v4.img TWRP
[Huawei P9 Guides, News, & Discussion] strba:
thank you for quick response, I think that I wiped out something of the system but not all... almost all my files are on the phone...images video music, also

I v mad at myself for the rush... I somehow do a factory reset and return to oreo 8 without IMEI sim card and other small things that make phone (again rushing :( )

I think now that I can restore the state to previous if something goes wrong I will put the post here

Happy new year, Nenad

p.s I was reading first instruction :),

twrp is powerfull
[Huawei P9 Guides, News, & Discussion] zgfg:
Photos, music, etc is on Internal memory or SD card, not needed for booting. System, Vendor and other partitions are crucial - don't affect them by TWRP

For IMEI, you need to flash again NW patch

Happy New Year ?
[Huawei P9 Guides, News, & Discussion] xxxvego:
Guys, how much SoT time do you take?

I am asking because I bought another new "original" battery and the battery disappears in sight ; /

Could it be the fault of the phone's age or software?

(I will add that I did a full wipe before replacing the battery).

Is the battery just a problem?
[Huawei P9 Guides, News, & Discussion] diablod:
hi guys... i made a mistake...hidden some root access to the apps with magisk manager perhaps i have hidden a system app so the phone now is in bootloop...what i must do? :(
[Huawei P9 Guides, News, & Discussion] zgfg:
Try the following:

- flash stock ramdisk and boot to system (without Magisk)

- uninstall Magisk Manager or wipe its data from Settings/app

- flash again the patched ramdisk and try to boot with Magisk

That way you only wiped MM database but not the database of Magisk itself, hence not sure would it help

If still in bootloop then read below:

---

Magisk keeps its database at /data/adb and Magisk Manager keeps its data at /data/user/0/com.topjohnwu.magisk (if you didn't repack Magisk Manager)

You could access those files by root explorer (eg MiXPlorer) if you successfully boot to the system - but you have bootloop.

You could access from TWRP only if you had decrypted internal storage - you probably didn't

Last option to delete them is Factory Reset.

But before Factory Reset you must flash back stock Recovery, (so no TWRP), Ramdisk, (and Kernel if you changed it)
[Huawei P9 Guides, News, & Discussion] diablod:
Thanks for the reply!! But if i press volume down+Power to enter in bootloader mode the phone enter in bootloop.. :(
[Huawei P9 Guides, News, & Discussion] zgfg:
Power off, disconnected from USB, keep pressed Vol- and then press Pow

But in that case you are not booting system, not starting Magisk, not reading MM data to find from which apps Magisk must hide.

It would mean that you did something else (worse), causing the bootloop even when system is not starting

Did you try reinstalling latest firmware from eRecovery?
[Huawei P9 Guides, News, & Discussion] pee9:
Maybe you should add microSD adapter/OTG cable to the requirements field in the first post? I am now stuck with no way to flash network patch because it was not clear until step 20 that this was needed.
[Huawei P9 Guides, News, & Discussion] any_body:
I am decided to do this rebrand / update procedure. (especially with [MENTION=7786725]zgfg[/MENTION] 's encouragement) :o

I opened my bootloder lock with code then i can install twrp with HWOTA7 tool, but then when i see twrp, i cant see "allow system modifications" step then nothing was happened after 2 times enter on my keyboard, i cant see the 8th step and i cant see "Upgrade Options" screen... :(

My folder structure's screen capture is attached to this post...

Can anybody help me?
[Huawei P9 Guides, News, & Discussion] zgfg:
TWRP was flashed successfully and you have problem in step (7) from post #2?

(?) but you don't see Swipe to allow system modifications - please make a screenshot from TWRP (simultaneously Vol- and Pow - display must blink, screenshot should be saved to Inernal memory, Pictures, Screenshots)

Few more hints to check

- OEM is unlocked, boot to Fasboot (keep pessing Vol- and boot with Pow) and check if both Bootloader/Phone and FRP are unlocked in red

- HWOTA tool is started on the PC with Admin privileges

- make sure that update.zip and two other update*.zip files do not have double zip extension, (common problem: file does have zip extension but Windows hide extensions by default and then people additionally rename update to update.zip and/or two other files - TWRP will look for update.ziip but could not find it because file is actually renamed to update.zip.zip

-make also a screenshot from TWRP settings, to see if it is correct TWRP - must be twrp-3.1.1-1-eva_extended.img
[Huawei P9 Guides, News, & Discussion] any_body:
There is no file named "twrp-3.1.1-1-eva_extended.img" in original HWOTA7 folder that downloaded from here but its looked like Openkirin's twrp 3.1.1 that i remembered. I will sent twrp's screenshot later when i check procedure second time...

The folder named "recovery" content's view (that in HWOTA7 folder downloaded from here) attached...

Also i attached all files wiev screen capture was attached in the past post to check by yourself (if possible... :o )
[Huawei P9 Guides, News, & Discussion] zgfg:
What is your starting point for this method - please screenshot of Settings/About
[Huawei P9 Guides, News, & Discussion] scaniathe:
it doesn't matter what your name is twrp I always call t.img and everything works of course you have to change the name everywhere
[Huawei P9 Guides, News, & Discussion] any_body:
The screenshot that you want is attached [MENTION=7786725]zgfg[/MENTION] :rolleyes:

Sorry but i cant understand you [MENTION=5901491]scaniathe[/MENTION] if you told me.
[Huawei P9 Guides, News, & Discussion] zgfg:
Maybe OP posts suggest to start with newer Nougat firmeares but for your c464 there aren't (except a little bit newer b390) and AFAIK this TWRP should work for any Nougat - ie any EMUI 5 (on P9 L09 or L19)

Hence, cannot imagine what could have gone wrong, maybe you can provide a screenshot from TWRP showing the missing Swipe option to Allow system modifications

And please remove the screenshot with your IMEI (or mask IMEI - you can even do basic editing of pictures directly from View and Edit, on the P9)
[Huawei P9 Guides, News, & Discussion] any_body:
I deleted IMEI in attached picture... I inform you, when i try procedure again asap...

I bought new phone yesterday, i am waiting for it's cargo tomorrow, after that, i can be relax to do these... :) :o
[Huawei P9 Guides, News, & Discussion] any_body:
I tried again now, but still i cant see step 7's "Upgrade Options" screen dear [MENTION=7786725]zgfg[/MENTION] :(

update_eng.bat's screen freezed step on that i attached picture...

Also i attached TWRP's screen capture this time...

On the other hand, my bootloader is not locked and twrp installed now in my phone's recovery, but when i try to run update_eng.bat script second time, i cant see "allow system modifications" slide after reboot my phone while its usb cable connected...

I am really disappointed and confused why i cant pass step 7... :rolleyes: :confused:
[Huawei P9 Guides, News, & Discussion] zgfg:
Your own TWRP screenshot attached back, with marks in orange

Step 7 says that you MUST swipe (fully to the right) to Allow system modifications. Swipe is there, it is not missing with your TWRP.

So swipe, then hit Enter as in step 7 instructions, that HWOTA7 can proceed giving you Upgrade options

And you MUST NOT checkmark Never show again, because TWRP will remember and won't present you next time - and you will not be able to pass the step 7 (and similarly later the step 15)
[Huawei P9 Guides, News, & Discussion] any_body:
I think you missunderstood me... :rolleyes:

I siwiped it already but nothing was happened in the HWOTA7 screen (on the windows pc, in cmd) frozen, it cant pass the next step (Upgrade Options)...
[Huawei P9 Guides, News, & Discussion] zgfg:
No idea, did not see anything like that. Did you start HWOTA7 with Admin privileges on the PC?
[Huawei P9 Guides, News, & Discussion] any_body:
Yes, as i said in the post before... :confused::eek: :(

On the other hand (of course you never have to do that but if possible) could you please check my directory structure of HWOTA7 on my windows laptop in the message https://xdaforums.com/showpost.php?p=81923219&postcount=1929

Because i cant be sure my folder structure is right about needed ROM's...

Even i opened nearly all .sh and .bat files of script (of HWOTA7) with advanced notepad editor to check path's on my windows laptop but i cant catch the mistake point of myself... :(

PS : I sent a pm to [MENTION=6870018]Tecalote[/MENTION] and may be he can find what is my mistake... :confused:
[Huawei P9 Guides, News, & Discussion] Tecalote:
Hi, the problem is simple. You have in the folder "update" (the second Screenshot you made) - two subfolders - and this doesn't work.

The three zip files for the first firmware update must be directly in the folder "update" - or you get no upgrade option.

Once you have updated you must move the 3 zip files to another place and then copy the next 3 zip files for the next Firmware update directly to the "update" folder.
[Huawei P9 Guides, News, & Discussion] any_body:
I said you and "thank you" but after that i still cant passed the same step instead of i moved 3 .zip files in the root of update folder... ?☹️?
[Huawei P9 Guides, News, & Discussion] any_body:
I tried this time to run the script without admin privileges but nothing was changed, the script still cant pass the step that could see at https://controlc.com/c93bcafb this address unfortunately... :(

I saw some error messages when i start the script like "the system cant find the file specified" two times and i saw "/tmp cant find" message, i create tmp folder in C:\HWOTA7 folder but nothing was changed again...

I am really try to run this procedure many many times but still i cant pass...

i am so sad, so disappointed, please help me (if someone wants i can donate him) that really i need....
[Huawei P9 Guides, News, & Discussion] Bonoros:
Hi everyone!!!

First of all, I want to thank all of you for the great effort you have made, especially @Tecalote et al.

Secondly, I wanted to know if any of you have experienced the same problem that I have.

I have updated my EVA-L09 to b540 (AL10) following the Tecalote's post and everything is operational except the front camera, so I cannot use the face unlock, which I was very interested in, nor make video calls on WhatsApp. When I switch from rear to front camera it does not start.

This is curious because before the update the rear camera did not work for me either, but with the update it has been activated again. I was expecting both to work, because they stopped working in some previous update at least 1 year ago, I think with the move to Android 7. I could only use the rear camera using Open Camera.

Has anyone experienced the same or know how to solve it?

Before the update my build was EVA-L09C432B505.

Thanks in advance.

erecovery !!!

Hi tecalote zgfg

zgfg once you helped me with unbricking my phone once again thanks to that

btw i just stumble on somehting i thought useful for those who may or will have to unbrick their phone with bootloader still being unlock.

This is what i just dit with al10 original chinese

1) i enter erecovery and download lastest...

2) once it reach to 12℅

3) i do factory reset in erecovery still

4) then i reboot the phone

5) it work fine

I did it twice and it works

for the first time i was thinking it was just a good luck because i did reboot my phone unintentionally

But now i think that s may be something else

becoz this time i did it purposedly coz i was worried to have my bootloader lock again if i download the full firmeware.

I my glad that s work for me

additionally what i dont know is if that s wil be the same result for you with the european model rebranded.
[Huawei P9 Guides, News, & Discussion] zgfg:
Unlocked Bootloader does not prevent (and does not cause a brick) for eRecovery, Install latest.

And Install latest with b540 will also not lock the Bootloader

Similarly with eRecovery, Factory reset - but before Factory reset make sure to have stock Recovery, Ramdisk (and Kernel) - otherwise you risk a brick
[Huawei P9 Guides, News, & Discussion] ogisha:
Hi guys!

I have EVA-L09C432B505 stock firmware.

I am rooted with Magisk and the bootloader is unlocked.

Recently, I started to get notification about the update to the new

EVA-L09C432B506 firmware.

I would like to update, so my question is what could be the best way to do it?

Thank you very much.

Best regards and stay safe!
[Huawei P9 Guides, News, & Discussion] zgfg:
Uninstall Magisk from Magisk Manager.

After that, you can additionally flash stock Boot image, but uninstalling Magisk should do

Flash also stock Recovery if you installed TWRP

Supposedly, Kernel and Recovery1 are stock ones (if you played with some, extract from update.zip from FullOTA-MF package for your b505 and flash from Fastboot)

With stock Boot, Recovery, Recovery1 and Kernel you are ready for OTA - I would keep FRP and Bootloader unlocked, just in case

OTA may lock FRP and Bootloader

Not sure what is new (newer Security patch) in b506. Don't know who tried b506 but I think nothing special or risky

You can contact me the other way
[Huawei P9 Guides, News, & Discussion] knobblysnail:
No Google services

Thanks for the update instructions. I now finally have Oreo on my L09, however I cannot log in to any Google service.

I have tried installing Google Play Services and the apps: GoogleInstaller_3.0 app and Google Services Assistant. They don’t seem to do anything, but they are in Chinese, which I don’t read.

I thought Google only banned access to new Huawei devices, or is this an effect of the AL10 locale being China?

To get Google services will I have to go back to C432B386?
[Huawei P9 Guides, News, & Discussion] zgfg:
Google Play Services and everything is already provided by b540 - you MUST NOT attempt to install by yourself

Please carefully read OP instructions and if necessary do Factory reset - before Factory resetting make sure you have stock Ramdisk (no Magisk) and stock Recovery (no TWRP)

Edit: Google Play Services is provided by b540 but Google Playstore apk not - this is clearly described in OP instructions

By installing Services manually, I'm afraid you messed things up and you better go to eRecovery, take Install latest and follow by Factory reset (read about stock Recovery, Ramdisk as warned you above), then repeat configuring b540 as in OP - but carefully follow OP, do not attempt to install Play Services or so, only install the latest Google Play app from mirror.apk.com
[Huawei P9 Guides, News, & Discussion] knobblysnail:
stuck in TWRP

I have managed to get myself further into trouble by trying to go to stock recovery by following all the steps of your OP:

A) Download and flash: Enable-Hwota.zip

B) Go back to the main menu of TWRP and Reboot to Bootlader

C) flash in Fastboot mode the Stock EMUI Recovery

as unfortunately I forgot to re-enable ADB+USB Debugging, so after steps A & B, when I got to C fastboot could not connect to the phone. Therefore I rebooted, but despite Developer mode being active, I couldn't access those settings. Meanwhile OTA auto-updated and rebooted straight into TWRP. Any suggestions where I could go now?
[Huawei P9 Guides, News, & Discussion] knobblysnail:
Thanks zgfg,

After a number of reboots I managed to get Fastboot to communicate and reinstall the stock recovery. While eRecovery failed Authentication, I did manage to do a factory reset from the stock recovery. I was pleasantly surprised to find the network patch still working, functioning Google Services :) and all the Chinese apps gone (including the browser, so I installed Google Play via OTG.).

So far in 540 the only thing which isn't working is Google Pay contactless payments - which is expected with the unlocked bootloader.

There is a System Update pending, so unless advised against I will let it. I'd want that done before I even considered rooting & Magisk to hide the unlocked bootloader from Google.
[Huawei P9 Guides, News, & Discussion] zgfg:
You actually didn't need to enable OTA for flashing stock Recovery and for eRecovery Install latest and Factory reset.

Also, for Fastboot, ADB debugging is not needed

Two options:

a) Switch off and disconnect from USB.

Press and keep pressing Vol+, press Pow.

It should boot to TWRP.

If you have stock Recovery image on SD card, you can flash it to Recovery directly from TWRP: In TWRP go to Install, Select storage SD Card, take Image files option, navigate to Recovery image, select Recovery for target and swipe to flash.

Reboot to Recovery (to verify is it stock Recovery) and then reboot to System/Android

b) Switch off..

Press and keep pressing Vol-, press Pow.

It should boot to Fastboot.

Connect to PC and flash Recovery.

Reboot to Recovery (to verify is it stock Recovery) and then reboot to System/Android

Supposing you didn't have Magisk so your Ramdisk is stock.

Then, after flashing stock Recovery you are ready for:

- Switch off, connect to charger!!!

Press and keep pressing Vol+, boot by Pow.

It should boot to eRecovery (not Recovery, because it was connected to charger) - here you have option to Install latest (it will do it over WiFi).

Once done, also from eRecovery take Factory reset and then reboot to System

---------- Post added at 09:46 AM ---------- Previous post was at 09:09 AM ----------

Our posts crissed-crossed?

Good to hear that you managed to Factory reset

Do you have b540 and OTA asks to patch something, not to install something higher than b540?

Then accept, it will not harm (but also nobody realized what was that Patch02).

Only a small OTA patch, it can do it even with TWRP installed.

After that, Settings/About will show b540 Patch02 as your version

That OTA Patch will also not bring Chinese bloatware, and SIM card(s) will continue working

With that OTA patch or without: If you install Magisk it will hide that Bootloder is unlocked but I don't know (I never used) if NFC payment would work

I think there was a discussion - try searching (top/right) for NFC, Contactless, Payment or so and find old posts about

If you decide to go for Magisk, don't follow old OP instructions, I can give you how to install directly the latest Magisk

Btw, Google account and Playstore works all ok now?
[Huawei P9 Guides, News, & Discussion] knobblysnail:
Thanks tecalote zgfg,

Yes, System Update shows it was just patch02 and Google account and Play Store are working perfectly.

I think I'll hold off installing Magisk for now, but if I decide to go ahead I'll ask you then for the latest installation method.

thanks again for your help.

If I'm on an OpenKirin ROM (RROS) should I go back to EMUI to manually update my firmware (from B528 to B540)?
[Huawei P9 Guides, News, & Discussion] zgfg:
When you return to EMUI, you will update to b540 either by OTA or by eRecovery, Install latest

I did it only once and 15 months ago, you can also search for in this thread - it was discussed, if I recall correctly the procedure to go back to EMUI was (do not attempt to flash from TWRP):

- must have stock Recovery, not TWRP

- boot to eRecovery (switch off, connect to charger, press and keep pressing Vol+, Pow on)

- take Install latest and follow by Factory reset

Once on b540, follow by Tecalote's patches
[Huawei P9 Guides, News, & Discussion] Gilgameshhhhhh:
So I can safely update my device (even on an OpenKirin ROM) thru eRecovery? What about process using OTA? How will that go? I guess using eRecovery will be the easiest of the two.
[Huawei P9 Guides, News, & Discussion] zgfg:
To come back to EMUI you need eRecovery, Install latest as described above. Hopefully, that latest will be directly b540 (maybe somebody else can comment who was similarly on OpenKirin installed over the old b528 or b535, and going back to EMUI at the time when b540 was available)

For OTA, as always, you need both WiFi and working SIM, give it some time or trigger by checking in Settings, System update

Even when already on EMUI, you can still go to eRecovery, Install latest and check what it offers

There is also an option to update from HiSuite - ofc, first must come back to EMUI

Use the Service Repair package for AL10 c00 b528, see:

https://xdaforums.com/showpost.php?p=78721851&postcount=1351

You will see, the official package contains detailed guide how to do the DLOAD

Once you install that b528, make Factory reset.

Hopefully, you will start receiving OTAs towards b540 - to speed up, you can check in System Updates

For OTA, you need a working SIM, you may need to install Tecalote's Network patch

Alternatively, you can also check for update from b538 to b535/b540 via eRecovery or even maybe HiSuite
