Please if you have problems with the custom LOS ROM, specially about telephony, ask/report at the corresponding place

This thread here is about rebranding and using that EMUI Oreo ROM. Who knows how that LOS ROM works, does it support telephony, and how to enable/fix

Particularly, check the following LOS 16 thread, it is about the Treble LOS ROM for P9 that you install over this EMUI Oreo.

But then, if there are questions about, ask there, directly to the developer - only there users and the developer could help:

Security warning that Bootloader is unlocked is common for all Android phones.

AFAIK, something that is enforced by Google, warning that vendors have to provide

Who doesn't like should stay with the locked Bootloader and stock ROM, and its OTA updates (as they last)

Step (29) and all there is optional. Like Magisk (btw, Magisk has been seriously updated and changed since 2018), enabling OTA updates for Oreo (it might be dangerous to blindly accept future OTA updates if/when they come since you never know would eg this Network patch still work), etc
[Huawei P9 Guides, News, & Discussion] fasteel:
Thanks for your reply. Agree that enabling OTA might be dangerous and future OTA may render the rebranded phone not working. The Huawei P9 is relatively old now and its hardware may not be adequate to deal with the latest system. Anyway it is fun to going through this whole process and I am sure in the future this P9 would end up being an antique.
[Huawei P9 Guides, News, & Discussion] Nicknackpaddywack101:
Sorry, I know where to post, but I was unaware that I posted on the wrong thread since I was posting that on a phone with the Lineageos thread in another window. Apparently the patch still works on Lineageos for the rebranded devices, but mine has a problem since it does not need a patch...

Well at least I think so.

Ill downgrade and try to do some testing.
[Huawei P9 Guides, News, & Discussion] daveh077:
So after 6 years I've finally had to move on from the P9, physical buttons were failing and Google navigation GPS kept freezing at crucial times no matter what I did.

But huge thanks to Tecalote and Zgfg for everything over the years here, this board gave my device a huge life extension.
[Huawei P9 Guides, News, & Discussion] Nicknackpaddywack101:
Mine just got a battery replacement from Officlal after-sales in China. Only costed me 99CNY (Less than 20 dollars)

The cost to mail the phone to China was higher than that, and Huawei only supports free shipping INSIDE China:rolleyes:

Ill see how long mine lasts... so far apart from battery issues everything works beautifully (the person who sold this phone to me said it was used 2016-2018, and he also kindly helped me pose myself as a "Chinese" so I could get official battery swap)

As a backup phone I won't need it much anyways...

Might try more tweaks such as flashing Pixelexperience GSI?
[Huawei P9 Guides, News, & Discussion] Nicknackpaddywack101:
Apparently the system partition was too small to flash pixelexperience...

Fortunately Huawei recovery servers are still on...

Yust see the first post in this thread and download P9-EVA-HWOTA7-v1.2 tool. it also contains all neccessary firmares.
[Huawei P9 Guides, News, & Discussion] 0lliver:
Hi, sorry newbie question, but this thread is very long to read up.

I have two P9 L19 (EU) since 2016 and both have version B386 / Emui 5 / Android 7.

Recently I replaced the battery myself and both P9 still work very well, apart from

- one reboots if i take a photo, except if it is on external battery (this is used stand-by only)

- the other loses GPS signal in navigation.

(when both were still under warranty I had sent them in to huawei service and they were returned with the comment 'reported error not found but repaired other errors'. when I got them back, both errors were still present, but I can live very well with them.)

I use only a few apps like wapp, threema, fdroid (k-9 mail, tutanota, telegram, freeOTP V2*, blokada 5**), and surf with Firefox with 'noscript' and 'ubloc origin' extensions enabled.

my question is, do I need to upgrade to a newer version of firmware or android for security reasons?

I plan to use these P9s for another 6 years :)

thanks!

*) finally after years of waiting redhat provided an update which allows backup/restore.

**) annoyingly blokada 5 never gets active again after sleep.
[Huawei P9 Guides, News, & Discussion] zgfg:
This is here actually a custom ROM (modified official Android 8), hence it can only be 'updated' by flashing, and that requires the unlocked Bootloader

You mainly need to read the post #2 for the installation instructions
[Huawei P9 Guides, News, & Discussion] 0lliver:
yes, I had already part of this thread and also saw it also works with linux instead of windows but my question was, if it would be worth the effort? what are the security risks if i stay with my Android7/B386?
[Huawei P9 Guides, News, & Discussion] zgfg:
The phone is end-of-line for years

With your stock ROM, you won't receive any updates, even Security patches from Google

With this Oreo (for China) you can see that Huawei still sends OTA updates (read the last pages in this thread)

Anyway, I moved out from Huawei in 2019, cannot advise you about "security risks"
[Huawei P9 Guides, News, & Discussion] 0lliver:
this 12GB download from mega requires to install their desktop app! isn't there another way with extra app?
[Huawei P9 Guides, News, & Discussion] zgfg:
You can download from browser or Mega app on the phone and unzip on the phone (to extract files) by using some more advanced file explorer like MiXPlorer

However, to install ROM(s) to the phone you have to follow the guide and use PC where required
[Huawei P9 Guides, News, & Discussion] 0lliver:
the header of post#2 with the 29 step install procedure says:

> 2022-06-21: This Post is under construction - please wait until the update is ready

should I wait?

though i still have an old laptop in the closet with outdated windows version, since years I use Linux on PC. I saw a link to a script how to accomplish the install, but it is 4 years old https://codeload.github.com/feedsbrain/hwota7/zip/refs/heads/master

is this script still viable?
[Huawei P9 Guides, News, & Discussion] zgfg:
Developer @Tecalote had updated the OP posts last year.

Maybe it still says under construction but AFAIK it could be used

I remember that there was a Linux script (maybe made by another user, based on the original Windows script) but I never used

Sorry, I cannot help you more, I no more use Huawei phones
[Huawei P9 Guides, News, & Discussion] 0lliver:
Thank you.

1. ordered a pre-owned (refurbished) "ǝuoɥdı 13"* with 3 years warranty for half a grand and a frog,

2. am currently downloading the (12 GB) P9-EVA-HWOTA7-v1.2.zip from mega with their linux desktop app (#sudo pacman -Syu pamac-aur ; #pamac build megasync-bin; #megasync),

3. once I accomplished the move to the new phone,

4. i'll upgrade my (still like new, still working fast) P9 to Oreo, and

5. if that brings me OTA, maybe I'll resell the new phone. ;)

*) have never been hooked on ǝlddɐ before, but I read they are generally withdrawing official support only after 5 years for updates to patch vulnerabilities.

I wonder what you mean with antique. Old but still useful? I doubt it will become a collectible.
[Huawei P9 Guides, News, & Discussion] kire456:
I followed this procedure successfully, and updated to Android 8 (my phone is an EVA-L09 originally). I flashed the EVA-B540 bootloader back, which in hindsight seems unwise as the build I installed is B552.. However, then I had the stupid* idea to lock the bootloader using the relock script, to hopefully make the device seem more legit to my banking apps. It's bricked now:

- Boots to the Huawei / powered by Android screen, nothing seems to happen afterwards

- Power+Vol+ does nothing (= reboots to the same Huawei Powered by Android screen), with or without usb cable

- Power+Vol- does nothing either, with or without usb cable. No fastboot to unlock the bootloader :(

- I placed the contents of the "2.EVA-AL10C00B552-Android-8" ZIP file in the sdcard\dload folder, and rebooted using Power+Vol-+Vol+. Still the same Huawei Powered by Android screen.

Is there any hope? Any ideas are welcome..

* Especially since right after the final step there's a note in red not to do that 🤡

---

Edit: following reports from MarkusP87 in this thread, I let the battery run dry and then connected the cable and pressed Vol-. Suddenly, fastboot! I have unlocked the bootloader and flashed TWRP back and am now un-bricked. And I'll stop flying so close to the sun now ;)
[Huawei P9 Guides, News, & Discussion] Premier4ever:
Anyone intersted in this? managed to get modified network patch to work with the latest update ... I will post it later, still testing.
[Huawei P9 Guides, News, & Discussion] maartenjd:
Of course I am curious. Everything that gets my P9 going. I wonder what this network patch does exactly. Keep up the good work!
[Huawei P9 Guides, News, & Discussion] Premier4ever:
Here it is .. Network patch v2.8 single sim, It is a tweaked and updated version based on the 2.6 version to make it work with all B5xx versions up to 566.

** Changelog:

* Added the latest version of AppGallery (HiSpace).

* Added the latest version of Huawei Backup (HwBackup).

* Added the latest version of Via web browser.

* Removed the chinese Huawei Cloud Drive and added the older European one v.7.2.3.33 ( It will be updated by AppGallery or by itself when it checks for update ).

* Removed ( GoogleCalendarSyncAdapter ) and ( GoogleTTS ) to prevent bootloops ( if you want them, look for a more compatible versions of them after you install the network patch and install them on running system ).

* Removed ( HwSecureIME ), ( HwSecurityMgrServices ) and ( HwUserExperience ) from the get go.

* Removed the chinese search libs, HwReader libs, and location libs as they are obviously a security risk and unwanted.

* Removed the chinese time syncing servers.

** Note: Wanted to add Google's keyboard but, it won't fit the system image, so, that was disappointing but you can install it afterwards.

**Installation:

* READ WHAT IS BELOW CAREFULLY BEFORE PROCEEDING .. YOU HAVE BEEN WARNED!

* Developer Options must be enabled ( ADB Debugging in charging only mode + USB Debugging (in this order) enabled ).

* Turn off your phone and remove you simcard.

* Boot into recovery ( TWRP ) and flash the network patch zip file.

* Recommended to be on a fresh copy of system ( no previous network patch installed, if not, then install this one over the older one .. wait for it to finish completely then wipe cache and delvik and then reboot system )

* After reboot, give it a couple of minutes to finish it's thing ( installations are runing in the background ).

* Turn off your phone, Insert your simcard and boot up normally, wait for it to find your network and enable 4G and mobile data .. enjoy.

** Note: if you enabled Wifi previously, reset your network settings ( go to settings, choose system, choose rest, choose network settings reset ) and reboot the phone.

[Huawei P9 Guides, News, & Discussion] Premier4ever:
More info please, like what version are you at? did an upgrade or fresh install? have you enabled wifi and bluetooth before installing the network patch?
[Huawei P9 Guides, News, & Discussion] Premier4ever:
Huawei removed ( googlewebview ) in B552, B558 and B566 that's why you face that issue. you need to do a fresh install of B540 and do manual updates to the desired version. As for GApps, I can't help you with it becuase I haven't tried.

Note: if you do an OTA update for B566, the updated will show a message telling you that some apps are un-athorised and it will ask you to remove them ... these apps are google web view and others. don't remove them or you will get back to the same issue.

[Huawei P9 Guides, News, & Discussion] Premier4ever:
Here is the link: https://mega.nz/folder/d8kCGSbK#Zl9eeN1NpABNyyMLT3Jsjw

B528 and B540 are major upgrade from android 7 to 8, B552 is a security patch plus fixes and updates here and there, the higher the version is better for security but you lose the google stuff after B540 unless you do manual upgrades (one by one and not OTA) to the requirded version. I recommend upgrading tell B558 and not B566 becuase of the issue I mentioned before.

As for the games, I can't be a good help there but, try managing the settings from the Dev. options .. If that didn't help then you need to seek other's help on the matter, sorry.

Download HuRUpdater_04 and put it into any folder with whatever name you want on the root of your sdcard together with the firmware zip files. The folder must contain 4 files like below:

HuRUpdater_04.zip

update.zip

update_all_hw.zip

update_data_public.zip

* Boot into TWRP, open "Wipe" and click Format Data, once done, Reboot Recovery.

* Go "Install", flash HuRUpdater_04.zip In some seconds the phone vibrates - in this moment press for one second the VOL- Button, HuRUpdater will flash automatically the Firmware.

* Once it is done, use on the left: Wipe Cache Button. Reboot RECOVERY.

* the device reboots into EMUI Stock Recovery. Perform Wipe Cache Partition and Factory reset and boot to system.

I also don't know the right link.

Perhaps @dkionline can help you.

He originally had a method to track down the links to the Filelist.xml. Using this link it is then possible to reconstruct the firmware links (3) (I could then do that too).
[Huawei P9 Guides, News, & Discussion] SideSkroll:
Hi. I know this is an old thread but its worth a shot...

I have a P9 which was originally an EVA-L09, a long(long) time ago I made the whole convertion to chinese (EVA-AL10) got Oreo and then flashed it to an old build of OpenKirin Omni rom.

I was trying to go back to stock (not sure if my "stock" would now be a chinese oreo or back to the original firmware) so I can update to the latest 2020 OEM and then flash LineageOS.

Is that possible? If so, how would I go about doing that?

Thanks in advance for any help you might provide.

I do have the unlock code. Thats as much as I still have from back when I did the whole thing.
[Huawei P9 Guides, News, & Discussion] Tecalote:
You can go back to Chinese Oreo Firmware, I declared it here:

Going back to original Oreo Firmware

Bevor updating to a compatible Lineage OS you must reflash the network patch.

You must check, if the LineageOS is compatible (because it requires same Android version, which is originally on the phone).

I can't support further, because I don't have this device anymore.
[Huawei P9 Guides, News, & Discussion] SideSkroll:
Thank you.

EDIT: You mention in your post that it is not possible to roll back from openkirin (which is what Im currently using, OmniRom)

Also, does eRecovery still work? I would guess t pulls the firmware from Huaweis servers... Which are offline if Im not mistaken?

Thanks again for replying.
[Huawei P9 Guides, News, & Discussion] Tecalote:
@SideSkroll

I don't know, if the Servers are offline.

You can just test.

It can be done from Open Kirin to > EMUI.

Phone must be connected with the charger and with Vol+ and Power Button you should be able to boot into Huawei eRecovery mode.

There you should see to download firmware by "download latest version and recovery"

You can test, if the firmware is available.

If it's online, you can install it. Important after installing is a complete factory reset.

Let me know, if it was successful or not possible cause offline servers.

I try to answer tomorrow or later in the evening.
[Huawei P9 Guides, News, & Discussion] SideSkroll:
I will do that as soon as my new battery gets here.

Not aure if I mentioned before but my phone WAS originally an EVA-L09 that I converted to EVA-AL10 to get Oreo... Dont know if that makes any difference? Meaning if the eRecovery works will it download the latest AL10 firmware +recovery or the original L09?

Also. Is the TWRP compatible with the latest firmware release (558 if Im not mistaken) I only need it to flash the network patch (which I presume I would need to do again after updating the firmware?)

No point in getting the phone up to date if the battery doesnt last more than 2-3 hours 😁

I'll let you know as soon as I try the procedure.

Thank you.
