Hi :)

Yes, you can do it with the same method (Please read OP Post #1 and Post#2)

Since I don't have oeminfo for L09c635 you wouldn't can go back (if you decide to go back from Oreo to Nougat and your original model) - that's why please share the oeminfo from your phone with me. I can integrate it to HWOTA7 (v1. 2)

1) HWOTA7 Tool installs automatically TWRP for Android 7 and you must boot to TWRP. Soon you are first time in TWRP please make a Backup of your "oeminfo" (only) to external SD (do not use internal storage, because this will be wiped)

2) Zip this Backup and load it up, so that I can download and integrate.

Here are the Download links for the latest EVA-L09c635 Japan version - you need it only for update to b398 (if your phone is not updated yet) and you would need it for rebranding back (if you decided not to stay on Oreo and going back to your original model).

All the steps for rebranding and update to Oreo are the same for EVA-L09 - EVA-L29 - EVA-L19
[Huawei P9 Guides, News, & Discussion] caocaolatre199x:
thanks you. After I update to the highest firmware version of android 7 and update android 8 in the same way as L09 euro, the download file is the same right?

and this is my OEMinfo.
[Huawei P9 Guides, News, & Discussion] Tecalote:
Yes, exactly. Just follow the Download links and steps in Post #2 (and remember to rename two zip files from each Firmware - you need just the two Firmwares for AL10 Nougat and Oreo, but each Firmware has three zip files)

Thanks for the oeminfo, I will include in the next version of HWOTA7. :good:

hello it's works fine for me in 528 but notifications games doesn't work, other application ok. Tip for push notifications ok. i don't understand why games not function

(sorry for my english)
[Huawei P9 Guides, News, & Discussion] Tecalote:
In Settings /Battery /Settings Symbol try to change back WLan in sleeping mode "in charging mode only" but keep mobile data "always on"

We found it, it works better for notifications in general.

I will edit the post about notifications soon I have time.

There are also other necessary settings - I will explain.

Note: Not all Apps /Games are updated for to work with Oreo correctly.
[Huawei P9 Guides, News, & Discussion] ledu205:
Ok i test this setting

Édit : same problem jurrasic World alive, clash royal, Outlook no notification. SMS Facebook Messenger, WhatsApp ok.

I think push notification unfuctional on my phone it's strange. ( I'm Root magisk)
[Huawei P9 Guides, News, & Discussion] Tecalote:
One thing is also necessary, Push Notifications are not working, if the App is restored from a Backup.

It must be fresh installed, don't know if you did?
[Huawei P9 Guides, News, & Discussion] ledu205:
fresh install just download from play store, only notification messaging work other app nothing notification. maybe wait B535 for resolve problem ?

Sorry I couldn't have a moment to try this but, I'm on download from recovery but the version is very different to your picture

EVA-AL10C00B398

Is this normal?
[Huawei P9 Guides, News, & Discussion] zgfg:
Seems that you are on an older version b398 instead of b399sp17a

When you recover, if you don't get b399sp17a by OTA you can install it by HWOTA7

Once you upgrade to b399sp1, proceed by instructions in posts #2 and #4
[Huawei P9 Guides, News, & Discussion] Tecalote:
I am wondering why you got b398 with eRecovery.

Normally, if you use eRecovery on b528 you would get b528 with eRecovery...

How is the actual state?
[Huawei P9 Guides, News, & Discussion] dbesoli:
When in b398 I tried to downgrade but the fastboot command failed to write ramdisk due to size error problem so, after several restarts and tries I downgraded to Nougat using the HiSuite method

Choosing previous version I got EVA-AL10C00b198 that is Android 6 :eek:

Now I'm updating from system updater with Wifi to B377

if after that I end on a version 7 will wait your feedback 'cos I'm currently lost

[update]

currently I'm on EVA-AL10C00B377 and going to take some sleep. Lets see tomorrow :rolleyes: because I don't understand how can I use HWOTA7 to go to an specific point. I suppose I can continue from the post #2 on the step that Phone is rebranded and Chinese Nougat version is installed.

[update2]

I've got auto update EVA-AL10C00B300SP17

I will try step 15 and following....

I think step 13 is wrong: " In Settings/Advanced settings menu disable: "Trust Space" and "HiSuite HDB". "

Trust Space option is directly on Settings menu after "Screen lock & passwords"

Settings/Trust Space

Settings/Adcvanced settings/Security->HiSuite HDB

[latest]

Well, definitively something went wrong on the way to bed but the good news are I'm on Oreo now with path [A]. Imei is there and SIM works

tomorrow will continue testing
[Huawei P9 Guides, News, & Discussion] iGSkill:
After I restore to Nougat from Oreo, do I need firmware files of EVA-L19 before rebranding back? It seems firmware finder is not working.
[Huawei P9 Guides, News, & Discussion] zgfg:
You have to do rebranding by HWOTA7 (Change location) as described in post #2 - but now in the opposite direction (from AL10 to L19).

Read also post #3.

When back to L19 go to Recovery and make Factory Reset and Wipe Cache and Internal
[Huawei P9 Guides, News, & Discussion] iGSkill:
"Just use Change location (for your original cust) and make sure, the Firmware is in the update folder." Does this mean I need firmware files of EVA-L19 or just simply rebrand?
[Huawei P9 Guides, News, & Discussion] zgfg:
Change location does for oeminfo but of course that you have to use also L19 ZIPs

Again, read post #2 which explains opposite direction and use imagination/logic to apply for the reverse :)
[Huawei P9 Guides, News, & Discussion] dbesoli:
Hello

after reinstalling yesterday as I explained on my previous post now I'm on [A] Stock firmware without root and NFC Payments works great.

Restarting the phone seems not to loose configuration and battery drain is much better than on Nougat.

Currently I'm on EVA-AL10 8.0.0.528(C00) and I've pending an update but no version is shown on interface. It only says that "this update fixes an issue where phone numbers in test messages could not be edited before dialing"

It's ok to go ahead with it?

Yes, if you stay without Root, it is safe to install

I have a question (i asked here https://xdaforums.com/p9/help/p9-telecom-brand-to-p9-nobrand-eva-t3847350 )

Can i Use the HWOTA7 to mod my P9 from Telecom Brand to P9 noBrand (from EVA-L09C55B386 to EVA-L09C432B505) ?

it's possible?

then, it's possible return back to EVA-L09C55 if i need (i need oeminfo i think, it's correct? because in folder of HWOTA it's not present)

thank you a lot
[Huawei P9 Guides, News, & Discussion] fpippo1999:
Yes you can!

For return back you have to back up oeminfo and give to [MENTION=6870018]Tecalote[/MENTION] so he will add it on the next versione of HWOTA
[Huawei P9 Guides, News, & Discussion] miksly:
Ah okay! So i need root to make oeminfo backup and use SDKTOOL to make backup and extract it... Its this the procedure i think...

Thanks
[Huawei P9 Guides, News, & Discussion] zgfg:
You don't need root.

Just flash (by Fastboot) TWRP for Huawei Nougat (read OP posts in this thread) and make backup of Oeminfo from TWRP

Actually, if your final goal is AL10c00b528 Oreo, you can upgrade directly to, no need for mid-step with L09c432, just follow the OP post #2
[Huawei P9 Guides, News, & Discussion] Tecalote:

And of course, it would be good, if you backup your original Telekom oeminfo - and share it with me. You can do it, as [MENTION=7786725]zgfg[/MENTION] told you

Can I use any cust when reverting to Nougat from Oreo? Because I can't remember my original cust. Can I use any EVA-L19XXXX firmware as long as its EVA-L19? Thanks in advance!
[Huawei P9 Guides, News, & Discussion] zgfg:
Yes but you (HWOTA7) must have oeminfo for that cust (like having for c432, c185, c636)
[Huawei P9 Guides, News, & Discussion] miksly:
OK! i have do all... thank you a lot.

i have 2 or 3 question...

1) have i a TWRP recovery now? i try POWER and VOL + but it don't enter in TWRP

2) now i have bootloades unlock. can i lock with fastboot ? if i unlock, my warranty became OK ?

thank you (only 2 question! ) :)
[Huawei P9 Guides, News, & Discussion] zgfg:
You can flash TWRP for Huawei Nougat from Fastboot as described:

https://xdaforums.com/p9/developmen...rainbow-v4-t3759292/post77622126#post77622126

Since you are on Nougat (on Oreo would be some important changes that must not be reset) you can relock Bootloader but be aware that it will Factory reset the phone (it will stay in c432b505 where you are now), hence you must use stock Backup app to backup/restore things if you want to keep them.

However, relocking Bootloader from Fastboot is not the same as if Bootloader is really locked, and Huawei service can still see that Bootloader was locked and relocked

PS: You must not have TWRP (neither root) if you are going to relock Bootloader - relocking Bootloader triggers Factory reset and it may soft brick the phone if recovery and boot partitions (Nougat) are custom

Btw check if Bootloader is already locked, maybe installation of b505 locked (not relocked) the Bootloader (some builds do it automatically)

You can check also by Fastboot (link to the post with Batch script using also this command is above)

fastboot oem get-bootinfo
[Huawei P9 Guides, News, & Discussion] miksly:
YES! it result LOCKED. So i think it's come back in warranty now?

thank you a loT!
[Huawei P9 Guides, News, & Discussion] zgfg:
I've never found a decisive info what really breaks the warranty or not

Maybe it also depends on how/where you bought the phone

Eg, your Bootloader is now locked but you switched the Cust - which was not possible without temporarily unlocking

They maybe keep a table of device ID + the original model/cust it was released with

Anyway, enjoy better software support here :)

I like oreo but it sounds very low in headphones there is a way to increase the volume
[Huawei P9 Guides, News, & Discussion] zgfg:
There is a pop-up asking you do you want to raise volume over the safe level

Anyway, you can try, I did but 'm not sure does it really change or was it placebo

Open by eg MiXploret, Root:

vendor/build.prop

Find the line and change true to false:

ro.config.music_lp_vol=true

Save and reboot

Make a bak copy of the file before changing (if anything goes wrong, you could reinstate the bak file even from TWRP)

PS: Or maybe another file

hw_oem/prop/local.prop

and the line

ro.config.hw.security_volume=8
[Huawei P9 Guides, News, & Discussion] dbesoli:
I haven't noticed any difference between Nougat and Oreo on volume levels. With cabled earphones, Bluetooth headset even in the car it's the same to me

I've a problem with Magisk.

Restarting, safety net check works ok but after several hours it fails.

I don't see any reason on Magisk logs.

Do you think is this an issue to be treated on this thread? (Related to our rebranded phone) or is something that I should translate to Magisk forum?
[Huawei P9 Guides, News, & Discussion] Tecalote:
This is only Magisk related and will be fixed in the next version of Magisk.

If safetynet check fail and before it was successful and later too - this doesn't mean, safetynet would fail.

It's only an issue of Magisk Manager
[Huawei P9 Guides, News, & Discussion] Tecalote:
You should perhaps buy new headphones, because if I hear music with headphones on Oreo it's great.

Perhaps you are not using the music app, which I have provided with the additional zip in Post 2 ?

I will wait for the next version of Magisk.

The Oreo ROM works as a charm. The phone is cold like a stone all the time. I'd only noticed that the File Manager from huawei doesn't let me long press to select a file (it crashes) but doesn't mind because I use the MIX file manager.

P9 or p9 plus face unlock :confused:
[Huawei P9 Guides, News, & Discussion] Tecalote:
I made one for P9 Plus and one for P9

- The Link I posted here is for P9.

(since I used the same Guide I made a Typo and wrote on two places "Plus" - it's corrected now, thanks for the hint)

And it works. ;)
[Huawei P9 Guides, News, & Discussion] zgfg:
Thanks a lot, it works

Just two commets

1) Upon downloading, ZIP must be moved to SD card (or OTG USB stick), because this TWRP cannot read from Internal (Downloads)

2) I enrolled my face, but then it didn't work properly, just pressing the Pow button instantaneously unlocked the screen (without waiting for a face, fingerprint or pin).

Then I changed (screenshot) from default Direct unlock to Slide to unlock and it started to work properly, by waiting to recognize my old, ugly face :)

Finally I moved back to Direct unlock and it now works correctly, waiting for face, fingerprint or pin

PS: Nice to have but not essential, one must press Pow and bring to face, hence fingerprint is faster/easier

Also, GPay does not work with Face (not considered secure?), but with Finger

[Huawei P9 Guides, News, & Discussion] zgfg:
Top-right on the page is Search box, enter Relock and push Search....

Relocking Bootloader trigers hard-reset - you loose changes and go to pure, stock v528 without Mobile connection

Besides, do you think you get your guarantee back because you relock Bootkoader (which ia not the same as originally locked Bootloader) - Huawei well knows that your device (per Device ID) was not realeased with Chinese cust

Post #2, you have two options (OTA no root, root no OTA - but for root you also need post #4).

In both cases you must have Mobile service if you correctly followed every detail from OP instructions - everybody else does have

But if you relocked the Bootloader then you must go back and repeat the procedure in post #2, from the point of b528 stock installation
