I found link and instruction for upgrade, unbrick, back from custom rom, etc....and I hope that it will be useful for the most people. My recommendation is to use force upgrade method with three buttons. Enjoy!

I used those service roms with same method for p10 lite, p9 lite. I didnt try this one, but, I dont expect any problem because instruction is provided by Huawei. Just, read instruction, but again my recommendation is force method. Because, normal upgrade is not necessary with this rom, ota, or ffinder are more efficient. But if someone bricked phone, or has custom rom, this is the best thing for rollback to stock rom. The reason why to use forced method iis simple, because with three buttons first flash stock recovery and than stock recovery automaticly repair all system and upgrade all things.

No, no this rom is not for rollback. Only if you have issues with Nougat mentioned servise rom is usefull. But if You try rollback from Emui 8 with this yiu can brick phone. For rollback from Emui 8 to Emui 5 must use official rollback from ffinder.

How can you downgrade from softbricked Oreo ROM where FFindar can't be loaded to Nougat ?

How did you brick phone on Emui 8? Only solution is to try to unlock bootloader in fasrboot and downgrade using twrp, hwota. Method for rollback you can find here in our section. https://forum.xda-developers.com/p10-plus/development/downgrade-p10-plus-oreo-to-nougat-t3724382
Regards and good luck.

Long story. Three days was trying to get it unbricked, even it was in service shop, but they didn't do much
however, upgrade from nougat to oreo didn't went well at first. Almost an hour it was installing oreo update zip file in twrp, so I had to turn off the mobile phone in middle of process. At last, it booted to Oreo, but after a first restart (changed overall appearance from large to medium), it just bootlooped. As I had nandroid backup of nougat in twrp, I tried to restore to that, and my problems just got bigger. I tried to go back to oreo again, multile times, different builds, but no luck. Than I found the method you linked, and with great help of guys from Telegram group, it booted again in OS. Hell yes
Strange thing that happend that it didn't booted to Nougat, but in Oreo acctually. Probably LowLevel format helped to fix partitions and stuff, after that bootloader was unlocked again, As for now I have bad Oreo version (8.0.0.046) will rollback again to Nougat.
I'm try to download but on half its stoped
Hi all I used this service rom and it got my phone working again but there are problems the dialer and contacts apps do not work anymore I had to Install 3rd party apps and software update is gone the project menu won't come up when you key in *#*#2846579#*#* command. Fastboot won't let me install twrp fastboot screen shows bootloader unlocked. Frp unlock As it stands I'm stuck with a working limited phone. Does anyone have any ideas I could try

Please let me know where I can find the service ROM for a VKY-L09 (P10 Plus).
The instructions on this forum are written very garbled and not clear enough for me to take a chance and upgrade my phone from Nougat to OREO.

I agree with you all instruction for p10 plus make confusion. You can try this to upgrade to Oreo https://forum.xda-developers.com/p10-plus/how-to/huawei-p10-plus-debrand-rebrand-update-t3715288
But, you have stock emui 5 or some custom rom? Im asking because if you had stock rom you had to get regular Ota to emui 8. If you have custom just try to.use Hwota method from mentioned link. I have similar procedure with Hwota for p10 lite so it could be usefull in your case just as example to see how it works
https://youtu.be/m2hZT1g0jtg
If you have stock firmware emui 5, stock recovery and locked bootloader you can try Ffinder for upgrade too.

Thank you for your reply. First reply from Huawei contributors. Thank you.
I have stock EMUI v5.10 and Android v7.0.
I unlocked the device, installed TWRP and rooted it.
I would like to upgrade to OREO and was hoping to find a solution that will allow me to upgrade using TWRP as it is working and installed.
Please advise.
Thank you once again.
Hi everyone! I decided to go back to stock from LineageOS 14.1, because 3D and AnTuTu Benchmark didn't work, just showing black screen and nothing happened. In any game did the same. So I decided to restore a TWRP backup, and I did that. It restored, but when i tried to boot up, it just stayed on the Honor logo. I tried to put the UPDATE.APP onto my SD-CARD and try to reinstall the OS, but I noticed something in TWRP, /data didn't mount for some dumb reason. I didn't think that was something bad so I ignored it. After installing the UPDATE.APP, it still does the same, stuck on Honor logo.
I know I f*cked it up, but now I want to get it fixed. Please help me !
Downgrading to EMUI 4.1 will fix it.

Tried downgrading to EMUI 4.1, and downgraded well, until it remained on the Honor logo screen. I tried with different versions of NEM-L21C432 stock roms for my phone, and only the ones with 13x worked to upgrade to, but the Nougat ones didn't. And it also blocked my bootloader again, because of the downgrade to EMUI 4.1 by holding both volume buttons and the power button.
If you downgrade, first u have to use downgrade package and then install rom version NEM-L21C432B132 and then use updater in settings to upgrade to nougat, dload method doesn't work with emui 5 roms.

The thing is I came back from a custom rom, more exactly the Lineage 14.1 developed by Meticulus, but it was EMUI 4.x based, so... yeah. It shows that the EMUI version is installed is NEM-L21C432B130. I tried upgrading through update.app and no luck. However, the bootloader locked. So, I send HuaweiMobileUK a tweet to give me the bootloader code for my phone. And sure enough, 2 days later, I have the bootloader code and unlocked the phone. I am going to attempt to install TWRP and then wipe everything except the SDCard and flash the update.zip with TWRP. I will try that and let you guys know if it worked.

Ok, so I tried wiping everything except the MicroSD Card and installing the update.zip FULL-OTA MF NEM-L21C432B132 and it worked. The phone still has the bootloader unlocked and now it works perfectly. So this is a good solution that worked for me ! Thank you guys for help anyways!
Hey,
I recently rebranded my VTR-L29C185 to VTR-L29C432. After that, I installed the latest Project Treble Resurrection Remix ROM from phh. The device is rooted, bootloader and frp unlocked, and has TWRP 3.2.1 FromFuture (the one for Treble roms) installed.
I made a full backup with TWRP 3.2.1-0 for stock EMUI 8.0 before the rebrand process.
My question is how do I go back to stock but keep the rebranding ? Do I just need to restore the backup without its OEMInfo via TWRP ? Search a VTR-L29C432 ROM and flash it through fastboot ?
The reason I want to go back to stock is mainly because of the many camera functions you cannot use on these roms even after installing the Huawei Camera (or the Google Camera for Kirin, which I recommend for users of these roms) and because of a few freezes and graphical glitches. Apart from that it's a very smooth and stable experience and I didn't face any big issue (gapps and root are working).
I would really appreciate your help. Thank you !
Anyone ?
should be fine to restore just the system image, because treble roms are just system partitions.

I did it, I'm on stock again now, but strangely it shows me there's an update with the same version as installed. If I try to run the update it reboots to try to install the update (logically) but with the fact I have TWRP installed it doesn't do so.
I also noticed the designs I download (which worked before on stock) do not apply. What does this mean ?
Thanks

So here's the deal, I had lost my LTE awhile back with something and saw the opportunity to fix it by taking the 8.1 soak OTA. Works wonderfully. But I do want to possibly go back a custom ROM, and have tried a few already that all work fine, except the lack of the fingerprint scanner working properly. This isn't really a big deal for now, but I'm starting a convo just to brainstorm.
Any ideas as to what's causing this, or possible solutions?
You may have to wait till the official hits the streets and the devs here tear it apart to bring that sensor up to date with the Bootloader I'm guessing. But hell, if you don't mind it. Dig in playa.

Using custom roms, all of which I tested, all worked using the xposed framework material, and using the magisk module corresponding to the version of android used (8.0 - 8.1)
As for stock rom 8.1, I do not know compatible kernel, for version 7.1, there is custom kernel available, and you should proceed xposed in the same way.

1>Take EFS backup from oreo soak test {with 4G and VOLTE working}
2>Flash Stock NPSS26.116-61-8 in full
3>Install TWRP and custom ROM
4>Restore EFS from oreo backup
This is working perfectly for me; fingerprint (incl gestures), VOLTE both work; I'm using AOSP Extended ROM

Perfect! I do have a question, how can I move my twrp backup to my desktop or so, and move it back to the phone after the firmware flash so I can restore my efs?
I tried something like that before and my backup was corrupted or unrecognizable.

Hmm, flashing the April 2018 7.1.1 firmware should give a security version downgrade if you've downgraded to Nougat from Oreo (though like yourself, I await some confirmation).
If you do see that error, I would advise against flashing or installing the June 2018 7.1.1 security update OTA, I do not know if flashing the 7.1.1 June 2018 OTA onto a device previously updated with the Oreo soak test would result in a hard brick (as the June 2018 OTA may or may not corrupt the Oreo bootloader). Be careful.
So if I were to attempt to flash it via fastboot, it would give me an error and ask for confirmation before proceeding, correct?
And if I see said error, stay away.

If you flash a stock firmware, you'll see the error, but it won't ask you for confirmation. It'll just display 'security version downgrade' if your bootloader is actually newer than the firmware you're flashing. Thus, fastboot should block you from downgrading the bootloader and GPT, so you'd likely still have the Oreo bootloader on your device (unless something's changed with Motorola's enforcement of bootloader versions).
The only time you may be okay is if the subsequent OTA is the same as the newest firmware that you had on your device. E.g. if you applied the soak test OTA (OPS28.49-2), then downgraded to the April 2018 firmware, if the next OTA you use is OPS28.49-2 or a newer Oreo OTA (as you have an Oreo bootloader), then you should be okay. If you however get a Nougat OTA (like the June 2018 security patch), I'd honestly stay away unless you want to risk it. Again, I do not know if the June 2018 7.1.1 would brick your device, but you've got no way of recovering your device besides paying for an expensive motherboard replacement. If you're on the soak test, try to stay on the soak test please.

Question. I've restored efs before after downgrading and it's worked. I would flash the custom rom of choice and if finger print and volte didn't work I would go back and restore efs from soaktest. I'm returning from soaktest again and that method doesn't seem to work. My question is, do you restore efs before you flash custom rom or do you wait till after the rom has flashed and reboot to check first?

Hi ! Don't be afraid, if you follow every step correctly you shouldn't have any problems, if you already unlocked your bootloader you should flash the latest version of TWRP if you want to root your phone, you can't use gcam unless you do it because you need to enable cam2api by adding a specific line to the build.prop.
If you decide to root it, just flash the treble version of TWRP and then flash the latest version of magisk, then you'll be able to modify your build.prop !
Ask me if you need any help

You don't need to backup the system image, just backup system, data and boot, and also persist and efs just in case you lose your IMEI. Are you using treble TRWP?
