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.

unlocked, twrp'd & rooted... what now?

I'm not really sure what I'm doing, I changed my country code from "demo" to eu and I'm on EVA-L09C432B182. There's so many different versions and I don't know which is good or even compatible. What would be the next thing you guys would do in order to get the most from my phone?
Edit - I just jumped in at the deep end and everything wen't well, I'm now on Nougat with emui 5.0, if you're in the same boat as I was, I used the Huawei Update in the second post of this thread: https://forum.xda-developers.com/p9/help/p9-7-0-nougat-update-eva-lo9-b182-t3539754"]https://forum.xda-developers.com/p9/help/p9-7-0-nougat-update-eva-lo9-b182-t3539754
worked a bloomin treat for me!

I have an eva-L09 with C900B190 and have country "demo" ??
I read a lot of posts how to get from the C900B190 to a Rom that has ota updates.
Before I start and because I am a bit of a noob I want to be absolutely sure I get all steps correct...please help me out and confirm/correct this
1) set develloper usb debugging
2) make sure phone connects to pc
3) install latest twrp
4) unlock boot loader with tool (https://forum.xda-developers.com/p9/development/huawei-p9-eva-l09-eva-l19-eva-l29-tool-t3591358)
5) make note of unlock code
6) use twrp to flash B136 (still have to find zip)
do I get ota to android 7 or I have to flash latest Rom meself (what is the best version for eva-L09?)
After that can I lock the boot loader and stay on android 7 or will the phone reset with locking and revert to android 6 again?
Thanks for helping

Contacted huawei, they were very helpful I will probably go to the service center to hopefully reset my phone to receive updates.
I also asked for an unlock code in case I need a plan B.

Seems I have no warranty (I got the phone from a friend and have no papers or anything) and have to pay for service centre. So I will try unlocking myself...
If anyone can help me out with all the steps in the right order I would be very grateful.

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.

P9 Lite not supported in New Zealand

I thought I would quickly let New Zealand P9 Lite owners know that for the past month I have been in a battle with Huawei. After months of saying they would be releasing EMUI 5 in New Zealand they have confirmed the past month that they, and I use their words "have no intention of releasing this update in New Zealand". Essential our phones stopped being supported in New Zealand in Septemeber 2016.
The good news is Huawei do not understand New Zealand law, they think that their TOS override the consumer guarantees Act. There is two reasons that you can get a full refund, one is that they have been releasing this update overseas and are simply just not releasing it in NZ. The other that last october Nick Stephens from Shellphish found some major bugs in the trust zone that allows a person to bypass the fingerprint scanner. Huawei released an update to this in december 2016 but did not and refuse to release it to NZ.
I talked to MEBI who advised me that the applicable law was.
“there is a guarantee that the manufacturer will take reasonable action to ensure that facilities for repair of the goods and supply of parts for the goods are reasonably available for a reasonable period after the goods are so supplied.” http://www.legislation.govt.nz/act/...sw_096be8ed814da84a_facilities_25_se&p=1&sr=1
That said we have just had a full refund for our 3 p9 lites. I suggest anyone else with a p9 lite that is waiting for these updates follow the same path and get a refund

Hmm, I purchased mine from Noel Leeming in July 2016, am I still eligible for the CGA return? I kinda want Nougat
I noticed on a geekzone post in mid June that someone got a reply from the Huawei Facebook page promising NZ p9 nougat!

Response from Huawei NZ "Please be advised the P9Lite software upgrade will be available in New Zealand towards the end of the year. Thanks"

Hi everyone. I work at Spark and have been talking with our device delivery manager. As of last month Huawei was saying that the update was not in the pipeline.. now they are telling us that the nougat update is in testing. I asked our team, testing what as it's already been released around the world?!
Either way. I got sick of waiting and followed a guide on here to change the localisation to update to b380. Let me tell you Nougat works much better!

Yeah it was a combination of a couple threads on here. Let me see if I can put something together.

Below is the steps I used to successfully change my NZ p9 lite to the global Nougat rom. USE AT YOUR OWN RISK. You 100% will reset your phone so backup and remove your data. I do not take any responsibility for this, you are attempting at your own risk. All credit goes to the authors in the links provided.
Step 1: unlock bootloader: https://forum.xda-developers.com/huawei-p9lite/how-to/guide-unlock-bootloader-twrp-root-t3405701
I did not use the tool to ender the code in this link, I just used ADB
Step 2: Using k1ll3r8e ‘s Toolkit, https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873
a. On his post, download pkg.L22C636_DS.zip. This gives you the oem info that you will need.
b. Flash TWRP (recovery) to the phone.
c. Backup stock recovery to be safe!
d. Restore oem in TWRP, but use from L22C636 info.
Step 3: Download Update.zip for VNS-L22C636B140 (have to be honest, not sure if I did B140 or 120…) from https://forum.xda-developers.com/hu...huawei-p9-lite-firmware-compilations-t3517124
A. Create a folder called dload in SD-card main.
B. Extract the file in dload UPDATE.APP folder from update.zip above
C. Turn off phone, disconnect from computer
D. Press both Volume keys (VOL UP and DOWN) and then the power key and hold until the software update starts.
Step 4: This will vary. For me, when I flashed the C636 oeminfo file it somehow relocked my bootloader and removed TWRP… if yours doesn’t you can follow standard procedure to do this.
Now you are on the global B636 rom.
Step 5: im not sure if eventually would get updated or not, but I then used Firmware Finder to force update (can get in play store): https://forum.xda-developers.com/tools/general/huawei-firmware-finder-team-mt-t3469146
I went from B140 to B360 to B380
What a difference!

Very interesting subject. I have enquired with Huawei to verify this. Debatable if I get any response; but worth a shot.
Can anyone download the VNS-L22C636B*** update files from the supplied link? I tried all 3, with both Chrome & Firefox, & no luck.

Sorry looks like the links are dead now . I do have it downloaded. let me see if I can get it up. If not, you can also use the Firmware finder to download them.

Well, I did receive a response to my query from Huawei. One can only hope it is accurate.
"Dear,
Thank you very much for contacting Huawei.
With regards to your inquiry, we would like to sincerely apologise for the delay as the update is still undergoing some testing on our devices to ensure that our users will fully enjoy the Nougat update for our devices. Not to worry as the update will be ready very soon and that you may stay tuned to our Official FB Page and Consumer Page for further updates pertaining the release of the device's update in the links below:"

P20 pro bricked!

Bricked my clt l29 c432
I had updated to new emui 9 .163
Used the funky downgrade firmware to go back to .156 and my phone got to 87%, shut down and bricked.
Is there any way back?
Im done with huawei this company is a joke. What year is it that you can still brick a phone from a simple downgrade.

Firmware downgrade is always risky. Anuway, i did this procedure twice and never had any issues.

the downgrade was from funky, not huawei, and he did confirm that he was able to downgrade twice, so the process itself works if completely correctly

The funky method bricked my phone. Funky support told me it should work from 163 to downgrade back to emui8. It bricked my phone.

That's why Huawei no longer sends unlock bootloader codes...

1) is your unit originally c432 or did you rebrand it (from c782)?
2) was the firmware u selected on fh website "Downgrade from EMUI9 to EMUI8 CLT-L29 8.1.0.156(C432)"?
I've used this method several times since September (both on beta and "stable") I did little research and It seems to be the first case on xda (p20 pro) when using this method resulted in hard brick so i try to figure out what could go wrong and even warn other users. This information can be very helpful for our community. I would appreciate your cooperation.

Thank You. This information is very helpful. I've used it with beta .47 ; .108 and "stable" .163.
I totally agree with dladz and I admit funky acted extremaly unprofessional. It's unacceptable when they charge custumers a lot and don't even test /know products they sell. They should've never suggested that method would work on your rebranded device without testing it thouroughly. Once You bricked your device they mercifully offered you discount? It's beyond ridiculous!

I asked funky if there was any way out of it, they replied not if it cant get into fastboot mode. I then asked if a replacement device came will they give me a bootloader code. The response 'we can offer a discount on a new code'.
I dont know what went wrong, i used the same hisuite method ive used for my last few updates.

The response I was expecting was, yeah your right have a free bootloader code if you get a replacement......nope...

Not sure why you even commented here. But I'll entertain it once.
Huawei is the problem.
Slow updates apart from european region.
Lack of any developer friendly software.
Lack of bootloading unlocking.
If there was only 1 region model of the phone then there wouldnt be thousands of people moaning of slow updates.
There also wouldnt be dozens of threads of people moaning about slow updates.
There would also be no need for the rip off that is funky huawei if there was no need for region changes.
To top it off this thread was made because I bricked my phone. In 2018 any phone that can be bricked is not a phone worth buying.
Cheers.

No slow updates here in germany. It comes in waves but where is the problem with a update 2 weeks later?
With the open bootloader the problem is that this is exactly what happened here. Therefore there is no Unlock Bootloader anymore because of all the funky huawei garbage.

You dont know what you're talking about. Who said my bootloader was unlocked? Who said there was a problem with the update? No one. The reason i went back was because i needed call recording and a file that I was told should have worked bricked my phone. Its as simple as that.
