Upgrade path from B123

I'm running a P7 with the firmware it shipped with and I'd really like to get it up to date, but every package I've tried so far has failed during package verification. There seems to be very little info on how to update your phone from such an old build. Can anyone please help because I'm at my wit's end here. I have a limited date cap so can't just keep downloading updates in the hopes that one of them will work.
I would be greatly indebted to anyone who could help me. This issue is making me want to cry.

Do you have a phone with a provider/network lock? Which roms did you try so far? You may give B133 a shot, if that doesn't work you'd have to go the way over a custom rom and then getting back to the stock one. I can describe the process more detailed in case it's necessary.

Thanks for the response!
I think the issue is that it is a network locked ROM. I got the phone from a provider called Vodacom and get their splash screen and everything. I went to speak to them and they told me I'm not supposed to be able to update my firmware because that requires rooting the phone, which voids my warranty. Sales people being sales people, I'm not sure how truthful this is. I can't imagine a provider refusing to let you update your phone.
So far I've tried B133, B609, B617 and B853, none of which works, sadly. Someone suggested I unlock the bootloader and I got the unlock code through the Huawei site, but when I try to boot using the three-button method it tells me that no update.app file was found, so I'm not sure how to get to where I enter the unlock code.

Hm, you might search around a bit and find an easier way, but if not, unlock the bootloader, flash twrp and any emui 2.3 based custom rom. Then flash the stock recovery and make a forced update (3 buttons) with B133.
To access the bootloader you have to press volume- and power until a white screen with some text appears.
Anyway, to update would definitely be worth it.

Yeah, I did precisely that last night and ended up soft-bricking my phone. It wouldn't even work when I flashed the original firmware. It's currently in at a repair shop and I hope they can fix it. Lesson learned though.
Thanks for the help anyway.

It's not that easy to hardbrick the P7, it's very likely that he will be able to fix it! With some time for trying, you probably would have been able to do it by yourself, too.
Your very welcome

Yeah, the thing is I was up all night trying to fix it. Flashing it back the original software should theoretically have done it, so I have no idea why it didn't.

Bricked P9 Plus VIE-L09C02

Can someone please help. I'm getting desperate now. I flashed a Nougat build a little while ago but had some issues with Bluetooth and NFC so I flashed back to the original firmware using the dload folder and 3 button method. The installation seemed to go through fine but get's stuck booting at the vodafone logo. It then takes me into eRecovery where it attempts to download latest version over wifi but fails. I don't really know where to go from here because I can't access the internal sd card because the phone won't boot. I can access fastboot but don't really know what to do from there.

Stevemacer10 Hello, I hope to be keen to help, because it happened to me the same thing, with two days of stomach ache for it. In wanting to load Android on my Nougat Huawei P9 Plus VIE-C02, with VIE-L09C605B354 and VIE-L29C185B320 I went into semi-brick or brick, or was only in bootloader, the screen with the green man to speak. No avail various ways, including via microSD-Fastboot or ADB to do restart your phone. Then, to my previous experience with a Huawei tablet, I logged on to the 'https://www.dc-unlocker.com/' site, and essend already registered, I bought 15 credits (15 Euros), for the 'option' DC Phoenix Firmware write ', valid for 72 hours, in addition to the program and downloaded the' DC program Phonix v29 '(https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial) following the related tutorial. Obviously procured the original firmware 'VIE-L09C02B133' or even lower versions, you'll have to unpack in a folder of your preference. Unfortunately, despite having used with DC Phoenix the original firmware was always also blocked me. At that point I wanted groped with a firmware that you can find on the same site of the DC-Unlocker (https://files.dc-unlocker.com/user.html?v=files/57694006a60d7) by downloading the firmware 'VIE_AL10B_M00A063_Factory_firmware_China_Nonspecific_Android_6.0_EMUI_4.1 .dgtks', which I loaded with DC-Phoenix on the phone. Rebooting of a minimal mode of andorid, I did not see well either. I went back into bootloader, as well as devone be made the previous steps that I have already described to you, and this time with DC-Phoenix I loaded on the phone firmware L09C02B128 and everything went well. Attention and keep in mind that just as I happened to me, the serial number of your phone is changed, to me has happened in '0123456789ABCDEF' and there was no way to change it, so as, while having the unlocked bootloader can not longer charge the TWRP recovery in order to then have root permissions. Until reading the paragraph '(Optional) Phone numbers REPAIR', I went to that point on the site 'http://hcu-client.com/'. Also here are sadly bought 8 credits (8,00 Euro) in order to work with the program 'HCU-Client v1.0.0.0115', you need to download and unpack, then follow the various instructions, which are not difficult when you have to be walked through the modding, otherwise you do even more damage. Let me know what you did and how it went to the method. I hope also good for you. In summary we want Euro 15 for Phoenix whose duration of operations applies to 72 hours and 8 Euro per HCU-Client, it can only use this for 24 hours.
P.S .: Obviously if you follow my instructions and all these signs you do so at your own risk, esonerandomi from every possible and accidental deterioration of the situation and the damage to your phone. Sorry for my English, whose translation has made Google translator.

I wanted to say that the change of the serial number does not work well. The serial number has been changed from what I've shown you above, but was not put one I added that I had from the sales box. I write support and maybe let you know what they tell me. See you soon.

Hi Grlshia,
Thanks for getting back to me. It's such a minefield playing with all these different regional variants. I have though, managed to get it completely fixed. I just gave in and took it into the local Vodafone store and fortunately there happened to be one of the tech experts in there that owned a P9. He took it off me and within about 5 minutes he had completely restored it. He told me he just did a factory reset by holding down vol+ and power. I'm sure I had tried this myself to no avail previously but that's what he said he did.

Stevemacer10 hello, I'm glad you've solved the problem. Unfortunately I'm still fighting because, for now I can only and even to load its firmware, but if you want to try to load the TWRP recovery for later obtain root permissions, it always fails. From what seems to understand me and certainly due to the fact that the bootloader unlock code now is different from what I have, because as I told you the serial number has changed and if I request a new unlock code, it stops notiziandomi the procedure that there is inconsistency between this number and the IMEI. For now I do not know what to do and how to proceed. I hope that over time can still solve my problem. A good evening to you :good:

i'v been throw it
after updating my p9 plus with a firmware that is not sutable to my area
my phone restarted and ask for an account wich ok but the problem was that the software not working properly and missing a keyboard.

try it.
it success with me , hope it work wth u

Still on Android 6.0/Emui 4.1.1

Hey, I got a Huawei P9 Plus phone and I was looking forward to the new Android version. Looks a lot better. Whenever I googled it said Huawei was supposed to rollout updates starting March. I never got it. And I see the P10 is already out that has Android 7.0/Emui 5.0, so I'm getting a little annoyed, why is my phone not receiving the update? It's probably my country (Israel) which seems to be really slow at these things I guess.
My build is: VIE-L09C576B180
I did some googling and searching on here and it seems that you can even upgrade without rooting/jailbreaking your device (something I don't want to do just yet, it's a new-ish phone and don't wanna risk ****ing something up), by using "Firmware Finder". So I installed the app and I see a whole list of builds and frankly I'm not sure what to do and which to get. I clicked on one and it showed a bunch of files I had to manually select and then hit "download". But frankly there's just very little info on how to proceed so I thought I'd make a topic, also to make sure what version is the one I should be downloading.
Thanks!

U can only update with same Cust u have C576, and there is no upgrade to your phone, B180 is the latest. If u want to debrand u must first unlock bootloader and install TWRP and root to change oeminfo and debrand it. Thats the only option.

My p10 is driving me nuts, system update and themes

Some update was downloaded yesterday and I lost some options like system updates which was next to the about phone option.
Also lost the ability to use themes, every time I select one the theme app just close and nothing changes.
I tried factory reset, and no luck there. Not really sure what else to do. And this is my first (and last) Android phone. Can someone please guide me on fixing these issues?
My device is VTR-L29-C649B170

I've managed to restore my device using the following guide:
stechguide com/download-huawei-p10-nougat-firmware-update/
However, still missing system updates...

Ok, last update.
I've managed to almost fully restore my phone, however, I had to rebrand it to L29C636 instead of the stock I had, I guess there's nothing I can do about that for now. I actually went to a technician and he said there's nothing much to he can do without breaking the warranty, so I did it myself...
I do want to thank Team TM for some guidance, tools and firmware database.

V40 is it possible to change NT Code without Root?

I have read through many posts here in the forum, where I got some tips that I have tried, but nothing that totally applied to my problem, only parts of it. I have upgraded my phone with every firmware of the Open_EU since January 2020 without any problem using LGUP. Last time I upgraded to Android 10 in August, it was also successful but then check nt-code: 222201: ff started to appear everytime I turned on the phone. It's annoying, but not a big problem since the phone works perfect. However I tried to upgrade to Android 10 v405ebw30c recently, and now LGUP can't make the upgrade, it says can't cross-DL, with a strange message judypn_lao_eea ->judypn_lao_com. Could the NT-code be the cause of this? I also tried to enter the hidden menu, *#546368#*405# and I can see the nt code, but I can't change it. Nothing happens. Will I have to root my phone to make this work? or are there other options?
Some history, this phone doesn't officially exist in Sweden, where I live. However, it's possible to buy it anyway. It was sold as brand new and unlocked. The first week I discovered that I couldn't make the officially update . Then I found out it's originally italian (TIM), and probably someone that unlocked afterwards. But maybe not properly made since it was problem to make upgrades with LG Bridge. And when I succefully managed to make the upgrade with LGUP I decided to keep the phone anyway, because I liked it too much. But since this NT code started to appear after the Android 10 upgrade, I wondered if maybe there's some "leftovers" from TIM italy. So is rooting the only option for me? Except for the upgrade problems it works perfect every day.

Thank you for your reply. Yes, I have read many instructions even on this page how to edit, cust_path_mapping.cfg, and that it's surely easy once the phone is rooted. But that's why I first wanted to see the possibilities to do this without that I have to root the phone.

So, u have 2 problems right? u want to upgrade to v405ebw30c, but can't, and you also have the nt-code error right?
First, no, they aren't related. I think that's highly unlikely. That's not something lgup checks for. I'd bet you're using the 1.14 version dll and should be using the 1.16 dll and should be doing a refurbish.
As far as the nt-code error. It's a pain, lots and lots of info about fixing it, most of them need root. But here's what worked for me, no root needed: I switched from att pie to Korean open Q (first time had the nt-error and no editing anything would fix it), so went back to att and then did the korean 409N again, first with partition DL. Let that finish, it has to reboot the phone completely to finish. Then, don't change the phone in anyway, just shut it off. Back to LGUP and do a Refurbish with the same kdz.
No more nt-error code. It *seems* that nt-error code info gets propagated to various partitions as a part of refurbish. I verified that the ftm partition, where that information lives, was completely spaces (blank) after the refurbish... it's odd, I know. But for whatever reason, I no longer have the nt-error code problem.
cheers

Thank you for your reply. No I don't know if they're related either, it was just a guess since the problems started at the same time. Well, I always had a kind of "problem" since I never have been able to upgrade from LG Bridge. And that I guess is from the NT-code. But the sign in the start appeared after the Android 10 upgrade. However, I'm using LGUP 1.16.0.3 and I have used it everytime, with DLL version 1.9.39.7.
And actually it wouldn't bother me too much having this sign in the start anyway, I only restart the phone like once per week. But of course it bothers me that I can't make the upgrade like before. And I can also mention that I have never tried to refurbish with LGUP, only upgrades, because I have some bank apps etc. that are a bit complicated to reinstall. Of course it's possible, but I have to be mentally prepared for it. So I'll only do that when I know there's no other option. And the phone work good today, so I'm not in a rush, but in a couple of months I should be doing an upgrade of course.
And thanks for telling me the other option too, I will surely try it one day but since it also requires refurbish I will try after I fail to make the normal refurbish.
I don't have any experience of rooting, if I root my phone, will I keep all the data or is it comparable to refurbish? Are the any other risks rooting the phone? I'll lose the warranty, but I don't really have the warranty anyway since it's not an official product in my country.

No, to root, you loose all data and have to start again. Part of rooting is to flash dm-verity which turns off encryption. But, that allows you to do a backup of the data partition once you've reinstalled everything. The positive side there is that in the future, you could back up that partition (data), make any other changes, then flash data back, and your apps would be back as they were.
Other risks? Well, maybe, if the phone was stolen I guess, it would be easier for someone to steal your data. Your situation, with serious banking apps, it **may be** you don't want that risk...
Maybe for just trying a refurb to lose nt-code, look at LG's 'restore' from previous device ability, use it to save off the apps somewhere, then restore after refurb? no root needed.
