[Huawei P9 Plus Guides, News, & Discussion] newbit:
Hello Fellows,

many thanks to you and both thumbs up for @Tecalote for this tool and all the information here.

The Script is a little bit buggy and the linux version doesn't work at all, but it did the trick.

In the second part I upgraded straight to VIE-AL10C00B552 and it basically worked. I did had some

time consuming trouble with the Playstore. Before the Playstore,

I've installed the both patches, NW and FU and installed Magisk Root via the Manager, with the Stock Ramdisk

extracted from Firmware files, set both Settings (DM and Force Encrypton to ON) and flashed it afterwards with fastboot.

So far so good, I failed all the SafetyNet tests and the Playstore just didn't want to let me log in. Not even the sign in button

showed any reaction, just nothing.After a while, I couldn't even install anymore any Playstore versions.

So the the solution for me was, to to go back to stock recovery -> full factory reset -> normal procedure with lots of agrees

and skips, and then I notices a little info in the top bar, google services got updated. And then it was gone.

In the Magisk Manager I had to do this additional install stuff and a reboot. Than back in the system, and MM,

I already passed basicintegrety, but not ctsprofile. For this I've installed the module Universal SafetyNet Fix from @kdrag0n,

also many thanks for this btw., and then I've passed all three tests. basicintegrety, ctsprofile, evaltyp BASIC

Now it let me install the Playstore apk, a very recent backup I've took before, and I could sign in without any further ado.

I didn't check for the GPay stuff, don't use it. But I've noticed some other stuff.

FaceUnlock and Wifi AC, Mobile Data works right after the patches.

The NFC Symbol is always shown in top bar, but there is no Tile to deactivate it.

I guess this is "normal" ?

Update 04.02.2021

I've just figured that NFC apps saying the NFC is off or is not supported.

Any advice how I can debug into this a bit deeper? Is there somewhere an explanation

what the patch file is actually doing in detail to enable it?

Update 05.02.2021

After some playing around with the different update/downgrade procedures. It looks like, if you have

no zip patch installed, there is always this "dead" NFC Symbol in the Tile Bar. It comes active or rather clickable

right after the NP is installed. If you patch it or net, as soon as you get to Version 552, the Tile Bar Symbol disappears completely.

After installing the NP, it just shows this NFC Symbol in the Top Bar, not the Tile Bar when you pull down the Top Bar. No NFC App

will work, it is not shown in the settings. When gone back to 550, it works as supposed to with the NP.

Maybe it is worth @Tecalote that you take a look into this?

I can't see any update button in the settings. I can search for it, and then I see it, but nothing happens when I hit it.

Update 05.02.2021

It is possible that If you say no updates in the beginning, after the first boot up to OS, the update option is taken out.

Any idea how to bring it back?

I can enable Wifi Calls, but couldn't test it yet.

Under Sound, when I hit Phone ringtone or Notification, nothing happens. It is supposed to let me choose a different sound.

Maybe this is an issue because I've deactivated a lot of Huawei apps I don't like/use.

I am really very grateful for this Tool and all the support here in this threat.

Cheers

NewBit

PS: A technical question pure of curiosity I do have. Why does the rebranding process, re-lock the bootloader? Is this something one did by purpose?

Or is this a side effect of this particular flashing? Or something else?
