First of all you don't flash TWRP (or anything else) from Recovery, but from Fastboot - please make sure that you carefully read once again complete OP instructions at the beginning of this thread

Second, you must NEVER flash TWRP for Nougat to Oreo or vice versa (Nougat and Oreo have completely different organisation of partitions and using e.g. TWRP for Nougat on Oreo will really brick your phone)

Specially don't flash wrong TWRP to eRecovery - in fact, don't flash anything over stock eRecovery because you may need eRecovery in such cases like a brick

On Chinese Oreo, FRP is usually unlocked, even if Bootloader gets locked.

And OEM Unlock switch is not available in Developer Options menu (although, once rooted, it can be added)

Now, it's completely unclear where are you are - have you really been trying to flash TWRP from Recovery (?), or from Fastboot but you just wrongly described above, have you flashed over eRecovery, etc

So you can try again, but flashing from Fastboot

Also, in one of the previous posts you have links to various b537 partition images, if you need to restore e.g. stock Recovery or Ramdisk

If you have really flashed over eRecovery, then you need to download update.zip from b537 FullOTA-MF from Firmware Finder, unzip, open update.app on PC in Huawei Update Extractor and extract recovery-ramdis2 image, to flash it back to its place

Once you restore stock Ramdisk, Recovery (and eRecovery - if you really messed over), then boot to eRecovery and let it (re)install the latest stock firmware

PS: If your FRP was really locked, then any flashing (not just flashing of right TWRP) will fail, hence one more thing that is not clear frpm your description (how flashing of Oreo TWRP to Recovery failed, but how then flashing Nougat TWRP to eRecovery succeeded, etc)
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
[MENTION=7786725]zgfg[/MENTION] One good thing: Flashing TWRP to the place of Huawei eRecovery (Second recovery) is not possible on Oreo. [MENTION=9711815]KobusLG[/MENTION] When you boot into Fastboot Mode what does the Bootloader Screen on the phone show: Bootloader unlocked → and why to you have FRP locked here? In Chinese Firmware (as zgfg mentioned) you do not have this option by default (have you modified here something in local.prop ?)

However - the only thing you can do is following:

1) By any chance flash back TWRP for Oreo with: fastboot flash recovery_ramdisk P9-VIE_EVA-8.0.0-TWRP-v4.img

2) Do exactly what is here described: https://xdaforums.com/showpost.php?p=78358816&postcount=384

3) After the Update is succesful and phone make automatically reboot it is in your situation probably required to boot once again to Stock EMUI Recovery (which will be installed after this method) and do Wipe Cache Partition and Factoryreset. Then it should boot normally.

OFC you have no network then and must again flash TWRP and the Network Patch....

Tell me how it goes.

If it does not work → I have another possibility more for you (but this would require the EMUI Stock Recovery instead of TWRP)

Double post - deleted.
[Huawei P9 Plus Guides, News, & Discussion] KobusLG:
Okay, So i managed to get TWRP on. I think the trick was noticing there's 2 different ways of getting to to the 2 recoveries. I noticed this before I saw your post. If I power on and press V-up in the 3-second window at the 'device not secure' window I always go to the same recovery, which is that base recovery (one with 4 menu items). But if I power down cold, hold V-up and then power, it goes to the right one - standard recovery with 3 options, or TWRP now.

Will check the rest of the instructions and post feedback.

[Huawei P9 Plus Guides, News, & Discussion] KobusLG:
Thanks zgfg, that clarifies things. Might be useful for the next person coming here in desperation.

Anyway I have a functional phone now.

One strange thing was that the google apps patch didn't seem to work as it did with the 535 version. It installed some of the apps, but not the play store or chrome. It did seem to install an older version of play services though. the first time after letting the update run, I couldn't get google stuff working. Every time I go to add a google account, the screen went blank for a few seconds, then nothing.

EMUI kept wanting to completely re-download the 2GB 537 update and reinstall it, so next I repoerformed the TWRP update, and then let it grab the update again. After That i reinstalled TWRP, applied the patches, and then google stuff worked. I had to install play-store from a loose APK though.... that still didn't work with the gapps zip patch. Anyways I think this time I'll leave TWRP on there, and leave OTA off.
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
IMO, it is better/easier to install Playstore app mamually, latest version from:

https://www.apkmirror.com/apk/google-inc/google-play-store/

I always do it that way:

- manually install GBoard, configure it and reboot,

- then manually install Playstore,

so without flashing the Playstore patch

[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
I release on Wednesday official the new Network Patch.

It's customized and doesn't have any Chinese menu anymore.

Location Sharing is fixed and a lot of other improvements.

I can't test it enaugh. I need a second contract for a SIM which supports Volte to get a chance for modify it on the right way.

This could be for the release after the next.

But the signals for all the different supported bands should be better with the new Release.

The new Patches for VIE-AL10c00 8.0.0.537 are released.

I will write during next week a changelog and update the main Thread. I had no time to do it (because I worked on the Patches and today it was too late).

But all required files can be found here:

https://www.androidfilehost.com/?w=files&flid=290469

Important:

- you must be on b537 to use the new Network Patch

- the new Patch requires the new FaceUnlock zip v1.5 (the old one will not work together)

- Wipe only Cache with TWRP after flashing the zip (with advanced wipe button) - not Dalvik

- Reboot, enjoy :)

[Huawei P9 Plus Guides, News, & Discussion] djyoshii:
Just a couple of battery related issues.

All's working well, however i did notice that when battery is at 20% or less (once the warning notification appears), anytime i open the camera and hit the shutter button, the phone will restart. Once the phone booted up again (now at 17%) i tried taking a photo again, and the same thing happened. This never used to happen on previous firmwares.

Also had one instance where it dropped from about 30% to 0%, this was the day after flashing B537 (with Patch02), I was using it with the Xiaomi Mini Drone, and immediately after connecting and taking off, the phone died.

I plugged it into the charger and checked the battery graph, as i was certain it wasn't empty, and it showed around 30% (as suspected) before its sudden shutdown. Since then i have not experienced this a second time.

EDIT:

Tested again last night at 20%. Same thing happened, press the shutter button and phone restarts.

After it booted up this time, it gave me the 'no power' warning and shut down.

Plugged it into the charger and it showed as charging from 19%.

Will do a fresh wipe/install again, and see if it fixes anything.

Sounds eerily like the common 6P battery issue, where it would die even though battery levels showed plenty of % left. Again, manufactured by Huawei.

Update for Guide in OP will come soon..

But for now you can download all actual files

recovery_ramdisk, ramdisk, patched ramdisk, Playstore and SwiftKey apk, NetworkPatch 2.5

from here:

https://androidfilehost.com/?w=files&flid=290469

OpenKirin Roms can only be flashed on Oreo - rebranded VIE-AL10 is officially supported.

Here's the installation Guide:

https://openkirin.net/user_guide/openkirin-rom-installation-instructions/

You need the original EMUI Recovery (recovery_ramdisk) installed (instead of TWRP)

You download the Rom and extract it with 7zip.

You flash the system.img in Fastboot mode.

After successfully flashing you reboot device with disconnected USB cable and Vol+ and Power Button immediately to EMUI Recovery.

From there you make Wipe Cache and Factoryreset.

Then boot into OpenKirin Rom.

Going back to EMUI can only be done with Huawei eRecovery Method + Factoryreset after restoring EMUI.

Omnirom pie can be updated ota, or it should always reflashed if a new version comes out?
[Huawei P9 Plus Guides, News, & Discussion] zgfg:
Open Kirin team does not have OTA servers to push, you must download and flash
[Huawei P9 Plus Guides, News, & Discussion] Tecalote:
It's right what [MENTION=7786725]zgfg[/MENTION] told you. But additional: if you stay on Omni Pie and flash a new version, you don't need to do always a Factoryreset.

Factoryreset is just required, if you come from EMUI.

But if you switch from Omni to another OpenKirin, you must first go back to EMUI (with eRecovery, then flashing again Network Patch)

Then you can try another OpenKirin.
[Huawei P9 Plus Guides, News, & Discussion] n206:
Thanks for the helps an advices ?
[Huawei P9 Plus Guides, News, & Discussion] djyoshii:
Thanks Tecalote.

Was playing around with it a little more, at 24% it doesn't shut down, but at 23% or lower it will reboot whenever the shutter button is used.

It also tends to completely shut down, and won't turn back on until placed on a charger. However once plugged into the charger, it will start from the % it died at (eg. 23%), although there were a couple of times where it started charging from around 30ish% which was odd, as it died at 20ish%

One other bug i noticed, Smart Unlock doesn't seem to work anymore. It was fine for the first couple of weeks after the update, but now i need to keep entering my PIN.

Confirmed device is still connected. Have restarted Bluetooth and the phone itself, re-enabled Smart Unlock, removed/re-added paired device, but no luck.

Will wait for the new Network Patch, and will probably reset and start from scratch again.

Switch to EMUI-Recovery (on any Firmwares)

Switch from TWRP to EMUI-Recovery (on any Firmwares)​

Since Huawei make always a new EMUI Recovery on every new Firmware, it is always required to extract recovery_ramdisk from update.app.

(In case you want to have Stock Recovery installed instead of TWRP → example for enabling OTA)

With following zip file, this is not required anymore.

I made a zip today, you can flash it with TWRP, if you like to have EMUI Recovery instead → and it is not dependend on the Firmware-Version.

The zip will restore the EMUI Recovery from the eRecovery Partition to recovery_ramdisk. → it is working on every Huawei Device on Oreo 8.0 or 8.1 (so far the device has TWRP)

After flashing the zip phone will reboot automatically to the EMUI Recovery of the current version.

But be patient, this takes a while (about 1 min it seems to be stuck on boot, but finally it will boot to EMUI-Recovery)

Hello everybody

I own a P9 Plus Vie-L09 that was originally Italian brand Tre (h3g)

I had problems with rebooting on camera usage and black screen (battery already changed two times) so I went trough the Oreo upgrade in post N2

Problems are still there so I would try to see if I can send to repair.

I was able to downgrade to Android 7 but it is still in Cinese cust/country

I would like to install VIE-L09ITAC555B375 firmware (H3g latest approved for my device) and I downloaded three files from FullOTA-MF (2,4GB)

To return to italian/H3g brand I saw I must have a oeminfo file for h3g/ita to use, right?

Where Can I find it? Can I use it with HWOTA7 then?

An old guide and for P9 EVA - but it doesn't matter, you have to go through the same main steps:

- "Download Latest version and Recovery" from eRecovery, in your case it will download and install VIE-AL10c00b537

- "Wipe Cache" & "Factory Reset/Wipe Data" from Recovery

- Reinstall latest NW patch and Face Unlock (optional) and root (optional)

Yes, for rebranding you will need HWOTA7 and oeminfo for desired cust.

Unfortunately, oeminfo cannot be extracted from the installation ZIPs.

You could have save it and give it to [MENTION=6870018]Tecalote[/MENTION] (to include it to its HWOTA7 package) before you rebranded to AL10.

AFAIK, there is no other way but asking somebody else who has VIE-L09ITAc555 to extract his oeminfo.
