Thanks, installed GBoard and was able to enable it.

Btw, I looked into Aoos and I don't see there SwiftKey, not even as disabled. At a glance it looks to me that some apps are missing, eg I don't see the usual Huawei bloatware.

However, when I started with L19c432b398/b399, it was brand new, not rooted, nothing disabled and specially nothing erased. Maybe there was a failure with flashing Data for c185 or something

HWOTA7 folders and such stuff - I strictly folliwed every your OP word. I read three times before I started (it took me two days to get ready to start) and while flashing I had OP opened in the PC browser.

So HWOTA7 folder on C, no subfolders. Old school, I'm on Windows 7. Etc.

I could only imagine one thing to cause problems on my PC at work, for HWOTA7 script failing to unlock bootloader. I don't have there Minimal ADB but the full blown Google development installation.

---

Leaving L19 c185 b402 as that for tonoght, otherwise it looks fine.

I'd like tomorrow to finally rebrand to AL10, but would like to be sure. that I again won't miss the keyboard (on hard-teset Huawei will remove GBoard).

As you say, I will tomprrow flash c185 b402 by HWOTA first to have it clean before rebranding to AL10

I mean that the "OTA for restore" don't wipe user data.

I only have to "patch" SIGNAL and NFC.

Thanks for your time and help!!

After using my rebranded P9 with Emui8 for quite a long time (thanks [MENTION=6870018]Tecalote[/MENTION]), it became a bit slow and I was experiencing some WiFi issues.

So I gave the OpenKirin LineageOS 16 build a try, by flashing it via fastboot on the system partition and used the stock recovery to make a factory reset. Everything went fine. LineageOS is running good, however there are some issues which unfortunately makes it not suitable as my personal daily driver.

So I want to go back to Emui8, and my question is:

Can I go back to Emui8 by just flashing the system image via fastboot, which I extracted from update.zip via Huawei Firmware Extractor.

Do I have to flash TWRP and the Network Patch again? Anything else?

Thanks.

Sorry, didn't read the last pages.

I restored it via eRecovery and reflashed TWRP and the NetworkPatch. Works .:good:

Guys need help regard OpenKirin. I have eva-l09 rebranded to al10 Oreo using Tacalote method. I wanted to try LineageOS 16.0 Build 4 and after flashing img there is need to factory reset in stock recovery but volume up+pwr always give me twrp so i done nothing. LineageOS starts etc but there was a problem with playstore not working and huawei backup couldn't install (tried also different ver apks) so i couldnt restore data from hisuite. Long story later, but in short.. im again on EVA-AL10C00B540 upgraded from old EVA-AL10b399Sp17a. I want to try again LineageOS but how to resolve factory reset in stock recovery after flashing? There is only twrp. Any suggestion? Thx in advance.
[Huawei P9 Guides, News, & Discussion] zgfg:
There is a thread devoted to Open-Kirin (find in P9, ROMs), so better address OpenKirin questions there

Be aware that OpenKirin Installation instructions strictly require to flash from Fastboot (!), not from TWRP, and they ask to use stock Recovery, not TWRP.

Vol+ & Pow (with charger not connected), boots to whatever you have in recovery partition.

If you keep TWRP there, how do you ecpect it to boot to the stock Recovery instead?!

You had to:

- flash b540 stock Recovery from TWRP or from Fastboot

- flash OpenKirin from Fastboot

- boot to Recovery and perform Factory reser

Btw, Factory reset option is also present in eRecovery (different partition and different recovery).

To boot to eRecovery, you must connect to the charger (!) and then boot with Vol+ & Pow
[Huawei P9 Guides, News, & Discussion] slayernn:
I think it was better to ask here as i used tutorial from this thread. After flashing b540 using hwota7 there was a need for twrp (for installing network patch etc) so twrp is present and that is what i dont understand. Is it posible to replace twrp with default default recovery and not doing any harm to system? Another question, if I flash OpenKirin from fastboot and do factory reset from eRecovery, will i have same result as if i use Recovery? Thanx for reply!
[Huawei P9 Guides, News, & Discussion] zgfg:
This thread here was for b540, not for OpenKirin.

And TWRP was needed to patch network fix and Face unlock patch

You found somewhere OpenKirin ROMs, you needed to research more to find and study their guides, find the XDA thread about (frankly, it's mostly dead), and Open Kirin Telegram channel to ask for help (but they are very rude there if channel is still alive and moderators+bot are kicking people out if they just mention TWRP)

Here you should start from:

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

https://xdaforums.com/p9/development/roms-openkirin-aosp-collection-t3828806

"...TWRP and other custom recoveries are not supported! Please ensure you have your device’s stock recovery installed...."

"...In the command window, enter the command fastboot flash system <name-of-rom-image-file>..."

I don't recall details, it was more than 1,5 years ago. I wanted to be smart and flashed their ROM from TWRP. I don't remember did I have bootloop or something didn't work, did I have to reinstall b540 again. Eventually, OpenKirin ROM properly booted when it was flashed from Fastboot

[Huawei P9 Guides, News, & Discussion] Tecalote:
Perhaps the downloaded Firmware Files are corrupted - or you didn't install the Chinese Firmware for Android 7?

Once location is changed to AL10 c00 you must flash the Android 7 Firmware for AL10 c00 - you can't go directly to Android 8 after changing oeminfo.

It's important to do every step and not skip any.

Got a new update today with july 2020 security patch, it however made the phone stuck at "your device has been unlocked and cant be trusted" "your device is booting now" screen. Restarting doesnt seem to work as the same happens. What can I do to fix it?
[Huawei P9 Guides, News, & Discussion] zgfg:
OTA requires stock Recovery (not TWRP) and stock Boot (no root)
[Huawei P9 Guides, News, & Discussion] Ooinaru:
Thanks for your reply, it seems that I posted in the wrong forum (p9 and not p9 plus), but I guess it doesnt matter as the outcome would probably be the same. As for stock recovery, I think I've got that, and no root btw :)

As for my issue, what can I do? is it possible to use Huawei erecovery or does this lock the bootloader?

---------- Post added at 09:43 PM ---------- Previous post was at 09:27 PM ----------

To be more specific; Does Huawei erecovery lock the bootloader?
[Huawei P9 Guides, News, & Discussion] zgfg:
Maybe it will lock, but you should have saved the code and you can use it again to unlock
[Huawei P9 Guides, News, & Discussion] Ooinaru:
Using Erecovery did not lock the bootloader thankfully! it just flashed over the current rom (stock oreo) so when the device rebooted i had no network coverage. I managed to sort this out by flashing twrp with fastboot and then applying the network patch :) Good to know for others that run into this issue!
[Huawei P9 Guides, News, & Discussion] a.simonelli:
Hi, I've got a european P9 rebranded successfully and updated to B540 with Network Patch and Face Unlock. I've got TWRP, ota disabled and no root. I'd like to update to July 2020 update (B550). Can I just enable OTA updates, switch back to stock recovery (like in step 29 of post #2), and update from settings? I'd like to avoid getting stuck like [MENTION=670038]Ooinaru[/MENTION] or lose data, thanks.
[Huawei P9 Guides, News, & Discussion] zgfg:
Generally yes.

See similar posts 3 days ago (although about P9 Plus but doesn't mater, methodolgy is the same) - just before yours. If OTA fails, you should be still able to update by eRecovery. Even if you loose Network patch (hopefully not) you should be able to flash the patch from TWRP
[Huawei P9 Guides, News, & Discussion] a.simonelli:
Thanks for the help. I managed to enable OTA updates, revert to stock recovery and successfully install one update that popped up in the settings, but it was just a patch (patch03). No signs of B550. Are there ways to force the OTA update?
[Huawei P9 Guides, News, & Discussion] zgfg:
Did you ever receive notification for OTA b550?

The fact that you had TWRP did not prevent you to receive OTA notifications, it would only cause OTA to fail if you accepted OTA

OTA is pushed to you, you cannot force their push. You must only have OTA enabled, and a valid SIM card (but it depends on your country and operator), and you can verify in Settings/Update - it pulls asking if there is an OTA approved for you (but not pushed yet)

Alternatively, you can try eRecovery, if Install latest firmware would opt you to download and install b550.

Also, use HiSuitte (not very old version - so best to use the latest), there is also an option there to update the firmware.

But if that b550 is not yet approved for your IMEI, no avail

Btw, I'm no more in the game - I have no more P9, so I don't know if this b550 was released and when and if anybody else is really receiving that b550 by OTA. Your post is the first here mentioning b550 - use the Search icon/field top-flight, search for b550, it finds only your posts since yesterday (?)
[Huawei P9 Guides, News, & Discussion] a.simonelli:
I didn't enable OTA updates so I couldn't see them, never received a notification because of that.

Tried HiSuite and eRecovery, no update available.

I found news about the update here. It's the same mentioned by the user just before me, the July 2020 security update. Firmware finder says that it's approved for installation on EVA-AL10-all-cn, among other models. Does this mean that it'll become available as an OTA in the next days?
[Huawei P9 Guides, News, & Discussion] zgfg:
Next days? - who knows (Huawei, not you or me) but to receive OTA updates you must enable OTA, then you will see if/when a notification will come
[Huawei P9 Guides, News, & Discussion] a.simonelli:

Hi unfortunatelly my rebranded EVAL L09 P9 OREO has been updated automatically to 550 at night. I lost network patch with this update.

Can I use EVA-L09_b540-SingleSIM_NetworkPatch-v2.6.zip to patch 550 ? Is there a new patch for 550 ?
[Huawei P9 Guides, News, & Discussion] NervReaper:
i flash the patch for EVA-L19 and everything its working without problem
[Huawei P9 Guides, News, & Discussion] a.simonelli:
Got the OTA, it failed to install in stock recovery. After some tries the phone rebooted to b540 and downloaded FULL-OTA, which installed successfully. After the update I had to go back to TWRP and flash the network patch, which worked fine. The face unlock patch on the other hand makes TWRP crash.
[Huawei P9 Guides, News, & Discussion] daveh077:
I was the same, the 600mb OTA didn't work, it would fail at 5% and reboot multiple times. But downloading the full size OTA worked. I'm now on build 550,

I did need to use the network patch after and i also needed to root the phone again using option A of post #4.

I dont normally flash the face unlock so i can't comment on that feature.

I can see the new smart battery capacity feature is enabled and i can see that the phone shows i'm now on the July 2020 security patch level. Everything else is the same.

Can you or [MENTION=9683515]daveh077[/MENTION]

please run the following commands in Terminal emulator and post the results:

getprop ro.product.manufacturer

getprop ro.product.model

getprop ro.build.fingerprint

getprop ro.build.version.security_patch

You cannot copy/paste from Terminal (you can copy/paste command by command to Terminal by long pressing) but there is an option to Send a session by e-mail - take it, then copy/paste and Discard the mail ?

Also, since commands and responses are long, it might be easier to work with Terminal in landscape mode

Thanks

Btw, does it pass SafetyNet (Basic Integrity and CTS Profile) - check with:

https://play.google.com/store/apps/details?id=com.scottyab.safetynet.sample

and is Device certified in Google Play?

I'm using magisk 20.4. Google play doesn't show if it's certified for me.
[Huawei P9 Guides, News, & Discussion] zgfg:
Thank you. I was asking since I don't have P9 anymore (one sold, the other had hardware issues) and I have passed to the newer phone and Android 10

Interesting, EVA-AL10 still passes CTS profile (without the need for additional tricks), hence Google doesn't detect that Bootloader is unlocked. Old phone, Google must not be forcing Hardware attest mode for CTS but the Basic mode in which case Magisk can easily hide the fact that Bootloader is unlocked (if you would be using Magisk Manager Canary, it would display it directly through its SafetyNet test, while for this app CTS mode enforced can be read from the logcat)

Anyway, since SafetyNet is passing, Play protect in Google play should be also ok - is it?

Then, does Google play display that Device is not certified or the info about Certification (last item in Settings) is altogether missing?

You could try the following:

- Airplane on

- Settings, Google Play app and Services and Google Framework Services: delete Cache and Data

- reboot, Airplane off and give a time to Google play to re-sync.

Since SafetyNet is passing, there is a chance that you could get Device Certified

is the b550 could b downloaded from one our post directly

zgfg, it's an honor to come back and resume our useful discussion and posts about phone android problems.

i was very busy that's why we're not being in touch

but now i have now sometimes to myself.

i think our last post between you and i was about

if using erecovery we do loose bootloader i did find

a way a strange one not letting all firmware downloaded and reboot and that's worked fine for me i did it twice without loosing the bootloader.

And [MENTION=670038]Ooinaru[/MENTION] did try erecovery by downloading all the the firmware same result no lost of bootloader and that's now we know two way get back the thing running normally and smoothly without having to pay or another bootloader code.

today my question is.

is there some post you know where i can get the b550 firmware and flash it manually?
[Huawei P9 Guides, News, & Discussion] zgfg:
Hi. There is b550 on Firmware Finder but it's not PV (just FullOTA-MF), hence cannot be upgraded by DLOAD

Cannot be flashed either by TWRP:

- TWRP from OP posts was taken from P9 Plus or something (there was no better at a time), it declares that device is VIE (or MHA, I don't recall anymore) and not EVA - since update.zip internally checks for device model (it was the case for b540 update.zip), flashing will fail findinf that device is not supported

- TWRP does not support encryption on Data (and Internal memory), hence flashing the parts of b550 that need to go to Data partition will fail

Only if you could find a newer TWRP for EVA, EMUI 8 on the Russian 4pda forum or some Chinese forum - IDK, no more in the game

eRecovery by itself does not re-lock Bootloader - it is a flag that may be or not in the particular stock firmware package (if it is, updating by OTA would also re-lock BL). b550 is a small update, hence they probably didn't go forcing to re-lock BL.

But even if update re-locks the Bootloader, just reuse your old BL code to unlock once again

There are other sites like androidhost.ru or support.halabtech.com where from time to time you could find the so-called Huawei official Service repair installation package - those are suitable for simple DLOAD installation (you must already be rebranded to AL10 but the phone could be bricked and even BL locked)

But the only Service repair package for P9 Oreo was b528 on that androidhost.ru (up to few months ago when I last checked) - and it works, it's useful for unbricking EVA-AL10 (upon to unbricking to b528, use OTAs to update to b540, or now even to b550)

Maybe one day (with some delay), you will find b550 Service repair package there (they don't call it like that, you must download, un-archive and look if there are official DLOAD instructions enclosed)

Also, you can google for 4pda huawei p9 Oreo or similar - to find Russian forum about. There you could probably find something newer (this thread is practically dead). Chrome can auto-translate Russian posts but to download any file (maybe even to open screenshot attachements), you need to register for their account. And that is tricky - you must pass a captcha you need to know Russian written cyrilics (from a picture - you cannot find an on-line OCR tool to help you to pass the question valid only a minute or so)

On halabtech (put aside their propaganda) you can find from a needle to the train. But from names you don't know what it really is, and to download anything serious or new you must buy the subscription (relatively not so cheap)

[Huawei P9 Guides, News, & Discussion] zgfg:
The same was answered in P9 Plus (VIE) thread (and I have double-checked with [MENTION=6870018]Tecalote[/MENTION]): If/when you would need (for future OTA, if it ever comes) stock Recovery, flash Switch-TWRP-to-EMUI-Recovery.zip and don't worry - it will not switch to the old b540 stock Recovery but to your latest b550 stock Recovery (for EVA or VIE, whichever is your phone)

Since you were updating to b550 from a working b540, you didn't need to install anything for Google play - it should have continue working like for the others who updated to b550 and did not have a problem with Google Play and Google account

If you didn't resolve the problem, try Factory reset from Settings (before Factory reset, you must uninstall Magisk)

Upon Factory reset, check if SIM(s) are working and re-apply Network patch (only) if needed.

Google Play Services comes with the firmware and you must not install Services, some Open Source GApps (if you are not familiar with and you know how to support yourself) or so

Just, if you would not find the Google Play(store) app, then install the latest version from apkmirror (not the two years old version from OP post #2):
