LON-L29C636B181 Rom is now rolling out! (Using Firmware Finder)

Since my mate 9 pro is detected by google as Mate 9 Porsche Design (LON-L29), I'm posting this as an update to everyone. Hopefully, Huawei will authenticate it as soon as I finished downloading.

Thanks but your model number is C636 whereas the PD is (i think) 721 so we won't get it for a while i bet...

Thanks - downloading now... 30% will edit post if it successful installs firmware..
Yeah - not authenticated yet.. oh well, give it a few days / week and it'll work!

I've just updated to L29C721B180 using funky Huawei and am incredibly pleased!!

Any moderator here? Any chance to get a dedicated Mate 9 Pro forum opened, to avoid all this confusion with firmware revisions?
And...pretty sick of seeing regular Funky Huawei promos popping up here and there...

there is actually a thread here in xda where you can request for a forum to be created. i already requested twice a couple of months ago but i think they're just ignoring my message. if were the moderator, i'll just combine pro and porsche design in one forum since they are typically the same device. they even have the same model code (LON-L29).

has anyone successfully updated their mate 9 pro to the latest one recently? huawei is still not authorizing this rom. smh

Nope.. still errors here with authentication..
I went as far as to try and get HiSuite to install it.. it looked promising, I had HiSuite find the update using a Proxy, then I told it to install, it downloaded the files (all 3 update zips/xml files) and then it pushed them into the phone, so I was surprised it got that far.. then it Rebooted the phone to run the upgrade.. but then it Failed at like 2%, with a error along the lines of unapproved/invalid firmware, so basically the same as Authentication Failed in the phone system updater... I thought maybe it used internet to confirm Authentication so I tried the same setup, but i removed the SIM cards and turned off Wifi, but got same error, so either it failed for not authenticated (not sure how it knows) or it failed because it didn't have internet to check..

HiSuite checks for authentication when it downloads the ROM. It pushes the authentication token from the computer to the phone. If there is no valid authentication token, it will not install.

Try Funky Huawei...
I know you have to pay for it, but at least you get the update.

i will think about it. i don't wanna pay for something that i can get for free.

maybe the reason why they didn't authenticate it is because they just release B182 rom.

is there a way to flash this update if i have rooted my phone?

Us M3 updated to 5.0 but issues now

Hey Guys,
I tried updating my tablet from 4.1 to 5.0 and now i am having some issues. I have no keyboard and my fingerprint sensor doesn't work anymore. So i have no way of doing anything. When I try to bring up the keyboard i get the google voice window.Build number shows BTV-W09C128B350. Trying to understand the steps i need to do to get my tablet back and running normally. Do I need to go back to 4.1? Any help would be greatly appreciated.
Thanks
Erik

How did you do the update? Did you use Firmware Finder and it's DNS update or did you use the dload folder method? I used the Firmware Finder method and everything went smoothly even with an unlocked bootloader, You might try to use that method to reinstall Nougat, but you will need a keyboard to change your DNS settings to the one Firmware Finder needs and for that I suggest you try a USB keyboard connected through an OTG cable.
I will say that once you get Nougat working, the 5Ghz radio goes back to not working and the file that needs to be updated to enable it seems to have changed. So far, I can not find the correct file/setting to change to enable it. For me it is more annoying that I can't get it working than necessary because I am getting between 20 and 40 Mbs with the 2.4Ghz radio and that is plenty fast for what I ask this tablet to do.

i Johje,
I was able to rollback to Android 6.0 and 4.1. Do you have instructions on how you did the Firmware finder update?
Thanks again for your help
Erik

I used Firmware Finder to update to the most recent Full Update for the US version. After Selecting the firmware choose "Get an update through DNS" and follow the instructions. This will install the beta Nougat and restore your recovery partitions even if you have an unlocked bootloader. Once the tablet has Nougat installed, root by installing TWRP to the Recovery2 partition which will replace eRecovery and leave your main recovery in place. Use TWRP to Flash Magisk and PHH Superuser to root the tablet because from my experience SuperSU does not work for Nougat on this table. Once rooted you can enable the 5Ghz radio by finding the "cfg_btv_hisi.ini" file in the "cust_spec\vendor\etc" directory and then just change "band_5g_enable=0" option to "band_5g_enable=1" , after rebooting the 5Ghz wireless will be enabled.
Hope this helps

I have also tried to update to 5.0. Everything seemed fine, but there is no keyboard, calc, file manager, etc. The "full..hw.." update seems to go really fast and it says it's done but there is no difference in what is on the tablet. Now I'm stuck at the point where it's A7.0, but I cannot do anything. Try getting google voice type to enter a complex email password
Any help on the second phase of the update is appreciated.

Can you use Firmware Finder in your tablet's current state? If so, try updating using Firmware FInder's DNS method. You will need to be able to update your network DNS settings, though. Have you tried using a corded keyboard connected through an OTG cable or a bluetooth keyboard?
I did not try using the dload method because earlier attempts an updating Marshmallow to a more recent build always failed because of my unlocked bootloader.

Unfortunately I could not fgure out how to do anything with it in that state (no keyboard, no internet, etc.). I tried to find a quality rollback for USA, but was not sure of what was out there that was correct. I ended up installing a EU version so at least it's working again (with old Android). I also realized the next day that my USB cord was bad and that's why I could not ADB or Fastboot anything. I'll try an upgrade again in the near future. Thx.

How do i get 7.0 on this tablet?

I just got this tablet from Amazon and it came with Android 6.0 and it says there is not an update available. How do I get stock 7.0 on it? I had read reviews that said it was updated which is one of the reasons I bought it.

I never got an OTA for 7 I had to use Firmware Finder in the play store. It found it, downloaded it and installed it.

Here’s how I upgraded. Reposted from another forum.
The update checker was a non-starter for me until I used it with firmware finder and bypassed having to use a micro+SD card in order to upgrade to EMUI 5. First, I picked the 2.5gb file option within firmware finder which is basically EMUI 5, chose the get an update using dns beta option. Added the dns address that firmware finder provided to my wifi settings by holding down your wifi, choosing modify network, tick advanced options, change settings to static, and then change the dns to the one provided by firmware finder. From there, it downloaded the file, but once finished it passed it on to Huawei's upgrader app and it took over from there. Just remember to remove the dns address from your wifi settings when finished. As I mentioned didn't need to use a SD card and once finished, checked the Huawei updator again and there was another small update available. I thought it was the easiest way to upgrade without having to do too many steps. Once the file was passed on to the Huawei upgrader, it did all the work.

Mediapad M3 Upgrade
Dear friend I have also bought these wonderful tablets these days, I have the same problem, so I installed "firmware finder" app so I can download the new firmware for emui 5.0 btv-w09c100b302, I do not know if the procedure is correct, light forums before upgrade, I would like someone to tell me if I can proceed safely with the upgrade, thank you

I posted how I did it above and it’s correct, and it’s safe. Follow the directions.

okay it's not super clear with Firmware Finder version 6.6 but I finally watched enough videos to figure it out.
Install Firmware Finder
Tap on your model number (should pop up right away at top)
Tap on latest FULL version
Check Firmware access
Tap IN-APP PROXY
Goto wifi settings and press hold your wifi
tap modify
show advanced
PROXY select manual
Proxy hostname: localhost
Proxy port 8080
save or connect
Go to Settings
system update
check for update. It should then show an update. Tap and let it download and install.
Edit: I do not recall having to change the DNS setting. I just checked and mine was still set to DHCP so I am sure I did not change it. Once done with update though do go back and remove the Proxy setting.

I got a BTV-W09C128B005 FW version (USA from Amazon). Updater didn't show any updates. I downloaded a two folder update. I unpacked them (.zip) and put on an SD card under 'dload'. I pressed the vol up/ vol down and power to start the update. It worked and went to BTV-W09C128B350. I then deleted the contents of the 'dload' folder on the SD card, and replaced them with the unpacked USA data upgrade files. The data folder included a lot of app .apks including one called 'bluetooth'. The force update for the 2nd set of files took very little time, and it didn't seem to do anything. It didn't update or install any apps from the data folder, and the vers. stayed at B350. Now bluetooth won't turn on, and the 'update' app is missing from the 'settings' menus. I can't use the other update methods because they use the missing update app.
Huawei cust. support chat assured me that the Android 7 update (OTA) would arrive if I was patient enough. (6 months, yeah right.)
I'm returning this to Amazon to start over. This time I'm going to try other methods that use the updater app, or log into the PC program HiSuite to see if it pushes the update properly.

You chose the complicated way to upgrade. My input ( above ) for how to upgrade is a lot easier and is less riskier as Huawei's upgrade software is involved. Your call, but if you hit a brick wall on other ways to upgrade, consider my suggestion.

I like it too with Android 7.0 , despite all the bloatware apps (I'm coming from a Nexus 7).

For me they installed without firmware finder. Right after first boot, I went to System Settings, and the Update section showed the OTA update. It installed 2. Only thing disappointing is that they haven't released an update to fix KRACK yet.

I wasn't so lucky: I had to install it with Firmware Finder (only the one of ~500MB).
Can you please tell me which security patch level do you have ?
I have those of May 2017.

That's what I have, May if 2017. I also used firmware finder and to my knowledge, that's the newest available for this tablet.

I did this too, because the instructions in FF app were crap for the other methods. I found the SD card method and ran with it. It didn't put the USA data files on that included the keyboard and bluetooth, and updater app.
I had to return mine to Amazon and try again using the DNS / Updater app method on FF. This time it worked great! This tablet is sooo much better with updated launcher and Android 7.
How on earth did you get it back to original state without sending it back?

I think there is a security patch level more recent than May '17.
I got my US version with the B005 FW vers. It had a SP level of something like Aug '17 (I don't remember exactly, but it after May of this year.)
It showed no updates in the updater app, but I upgraded it using FF app, and now it says May '17 for the SP level.
I don't think Huawei ever intended US versions to get the Android 7 update because it doesn't comply with current SP levels.

Hi all, I have a question, when I open Firmware Finder I have a list of 4 FullOTA (see attached screenshot), all with the same release date, how can I choose the right one?

@fidrat I worded that poorly. I used the same technique you did, started with a new one.

Best path to Pie upgrade?

Picked up a Moto 6 Plus (XT1926-7, retla) last month and have been running the latest 8.0 (8.0.0_OPWS27.113-89-5) with unlocked bootloader and Magisk. Working flawless. :good:
Decided to take the plunge to Pie last night, which ended up with me have to do a full restore of a 8.0.0_OPWS27.113-89-5, then taking the OTA to 9.0
Upon successful OTA to 9.0, I then rebooted and used fastboot TWRP to try to take a clean nandroid backup. I could backup all partitions except Data (fork failure to make the rar).
I then rebooted again (still stock, no Magisk install yet), and noticed that I was getting a "dm-verity disabled" warning on my bootup screen and then a warning under System Update check that says "Updates are disable for this device due to compromised system integrity".
Have others tried the same yet? Is this "compromise" due to the unlocked bootloader, or did TWRP trip something? Is it possible to run Pie with Magisk and still be a google certified device?

Just tried again:
* Clean wipe and install to 8.0 (89-5)
* Bare bones phone config.
* enable USB Debug
* Accepted OTA Update and reboot
* Successful update to 9.0 (PPW29.116-11, patch level Dec 1, 2018)
* Play Store version 13.0.23-all [0] [PR] 227930514
* enable USB Debug
* reboot
* following warning on the blue/yellow bootup screen: "Verity mode is set to disabled"
* System Update page: "System Integrity is Compromised", "As your device system integrity is compromised, it is no longer eligible for software updates. Please contact customer service to re-program the device with official software."
EDIT:
* Magisk rooting still works: https://forum.xda-developers.com/g6-plus/how-to/3-how-to-install-root-aka-magisk-t3854244

May i ask you a question kind sir. I have the same model (G6 plus) de same oppw thingy (8.0.0_OPWS27.113-89-5) and when i hit the update button did not get any OTA. It says i have the latest version and still in november security patch. How did you trigger the OTA? Or you sideload it? Thanks kind sir

Nice to see that you had an OTA to Pie. I was about to ask where you live, because I don't have the OTA here in Belgium yet. But then I saw you have a RETLA device, so I guess I will have to wait some more!
Is the phone working well on Pie?

I've used both, but the installed one worked identically so far for backing up and installing Magisk.

Yep.. purchased on Amazon in the US (I don't think they ever officially released G6+ model direct to US). So far, working smooth. Haven't found any bugs.
Should also note that even with the Verity and "not update eligible" issues, and now rooted with Magisk, it does still show as Play Store Certified.

@thump i am in the retla too. I did not get the pop up update neither via security o update section. I have the same OPWS as yours too ??

Weird. Mine badgered me every hour with a "Software Update is Available" notification for the past week. Even when I did the clean stock reflash to 89-5, it notified me a few minutes after clean reboot, before I even got around to checking System Updates. Maybe rolling it out in staggered waves of some type?

P9 Lite - VNS-L31C432B226 to Nougat

Hi guys!
Recently, one of the users of my app reported an issue with his Huawei P9 Lite VNS-L31C432B418. It's impossible to him to use my app, network calls are blocked in the app, the app won't connect to my backend endpoints for no reason. Logging is quite unclear, so it's hard to reproduce this issue.
Because of my dedication and urge to fix this issue, I ordered an Huawei P9 Lite on Amazon. (amazon.de/-/en/gp/product/B01DYN5OLE) It got delivered today, installed my app and woosh... Everything was working fine. The phone came with VNS-L31C432B160/EMUI 4.1.3; but the user of my app is using P9 Lite VNS-L31C432B418/EMUI 5.0.4. Hitting the "check for updates" did not result in receiving any update (Thanks Huawei!) so I started looking around the internet. I prefer to use exactly the same build version because I want to reproduce this (hard) issue.
So far so good, I used Firmware Finder to incrementally update to VNS-L31C432B226. I'm quite new in these firmware-hacks and tried installing the VNS-L31C432B418 version, but I got stuck at the 5% progress indicator. Using Firmware Finder on my PC, it checked that I'm able to install versions with G 2190 and g 1789. These params do not tell that much for me... Currently, I'm stuck at VNS-L31C432B226 as this is the last one that has G 2190 and g 1789. All the other ones have G 190 and g 1755, are these for other devices as the one I have since I am not able to install these ones?
Someone who can help me in order to get VNS-L31C432B418? Is this even possible on my device?
Thanks in advance, kind regards

Hi guys!
Recently, one of the users of my app reported an issue with his Huawei P9 Lite VNS-L31C432B418. It's impossible to him to use my app, network calls are blocked in the app, the app won't connect to my backend endpoints for no reason. Logging is quite unclear, so it's hard to reproduce this issue.
Because of my dedication and urge to fix this issue, I ordered an Huawei P9 Lite on Amazon. (amazon.de/-/en/gp/product/B01DYN5OLE) It got delivered today, installed my app and woosh... Everything was working fine. The phone came with VNS-L31C432B160/EMUI 4.1.3; but the user of my app is using P9 Lite VNS-L31C432B418/EMUI 5.0.4. Hitting the "check for updates" did not result in receiving any update (Thanks Huawei!) so I started looking around the internet. I prefer to use exactly the same build version because I want to reproduce this (hard) issue.
So far so good, I used Firmware Finder to incrementally update to VNS-L31C432B226. I'm quite new in these firmware-hacks and tried installing the VNS-L31C432B418 version, but I got stuck at the 5% progress indicator. Using Firmware Finder on my PC, it checked that I'm able to install versions with G 2190 and g 1789. These params do not tell that much for me...

Hi Joren,
sorry if i ask but the weird (B226) update you done is android 6 or 7 ?
Starting from B160, you should have chosen B370 FULLOTA-MF-PV
to upgrade to android 7, then to latest B418...

Hi, thanks for your reply! My device gotdelivered with version B172...
Today, I got an update to VNS-L31C432B228! This version is not visible in Firmware Finder... Any ideas how to update to Nougat?
Is it possible to force the update? I always get the message that the update is not compatible with my version.

Ok,
use the app, same method and choose B370 FULLOTA-MF-PV.
It's 1.99 gbyte - date 21/03/2017 - G 753 - g 104.
Into my PC version of FF i see (2) two versions, looks the same, try one or the other..
If you will succeed you can update to the latest firmware (B418)..

It seems to be the same URL for those two entries. Note that it's in fact a "downgrade", the "v" value is 80460. My device got delivered with B172 (which is also not found in FF), B173 is already 110304... Currently, B228 is also not visible in the list, B227 is 143951.

Unzipped "update.zip", copied it into dload folder on my SD card, *#*#2846579#*#* =, ProjectMenu -> Software Upgrade -> SDCard Upgrade ->OK
"Software install failed" "Incompatibility with current version. Please download the correct update package". Same story for the contents of the update_data_full_VNS-L31_hw_eu.zip.
I'd like to wipe the current firmware instead op updating/upgrading it, but I've already done lots of research, some docs are so outdated that they're not relevant anymore. Any clear steps on how to force install the version instead op upgrading it?

Dude, i'm here to help, at least for what i know...
I think i explained not so good...
You should use the app to upgrade not to download the firmware.
Take a look HERE, also some videos are on YT..
Just change the firmware with yours... :fingers-crossed:

Tried in the app, it told me that B370 "The firmware is not approved for installation". B418 is approved (FullOTA-MF), so:
- I've downloaded the firmware (3 files)
- Setup in-app proxy
- Change wifi proxy to localhost:8080
- Check for updates, update is available
- Switch back to wifi, disable proxy
- Download update
- Install
Same story, update is incompatible... So I think I'm still doing something wrong while changing the firmware instead of upgrading. For me, the tutorials are skipping essential steps. Or I might have received a f*cked up device. Why on earth is it so hard to update, thanks Huawei..

Are you choosing B370 fullota-mf-pv one ? (not B370 fullota-mf nor B370 ota)
Also now i see there a third B370 fullota-mf-pv with date 2017.08.03 - G 1258 - g 104..
If you don't upgrade to this version first,
you couldn't upgrade anyway to android 7
and then to latest version.
Come on try again...

Yup, but that one: "Most likely, the firmware was removed from the server".
The other ones with B370 are both telling "The firmware is not approved for installation".
I'm testing all the FullOTA-MF-PV's, they are all telling "The firmware is not approved for installation". Some of the "FullOTA-MF" do show the message that they are available. What's the difference between the "-PV"?

That version is used to upgrade to android 7 from 6.
Maybe the version you updated before (B226/B228) don't allow you to upgrade.
Downgrade to B160 and redo your steps..
How to do this ?
Download THIS FILE, extract update.app, create a folder and name it DLOAD.
Put update.app into that folder and put the folder into your SD card.
Turn off the device then reboot holding vol+ & vol- & power buttons together
until flashing starts then release them...

Done, thanks for those clear instructions, I do have B160 for now. The B370 is still resulting in "The firmware is not approved for installation"... :/

That's really weird dude..
Is your device dual sim one ?
What happen if you choose B371 (fullota-mf-pv) instead of B370 ?

Yup, the device is the dual sim one, B371 also "The firmware is not approved for installation". It's really weird...
I'll try updating manually incrementally, so update by update the ones with G 1258 - g 104?

Back to B370,
skip the verify access firmware, go directly to 'get an update via dns',
tap ok, select 'auto' dns method and tap change dns.
VPN service should start...
Open settings > internal updater
and see if download come for you... check several times ...

I don't know what's wrong with this device.
I've downgraded my device to B160 (66015), tried upgrading to B370 80460, 80466, 80582, all with the same result: Incompatibility with current version. The only version I'm able to upgrade to is 80562, which is B210. From that point, Firmware Finder suggests that it should be possible to update to the B370 builds, but every time, "Incompatibility with current version".
The only B370 that I was not able to try is the one you're suggesting in your comment. That one gives a 404 so I'm not able to download that one (92405). Any other suggestions...?

Sorry dude have you tried skipping the firmware access ?
Could we have missed something in the procedure ?
If this doesn't work, try opening the FF app and from the main menu select 'instructions'.
Video and text guides will open. You can try the update with HiSuite
or with eRecovery or as a last resort you could try the one with a TWRP,
but for this you will have to unlock the bootloader and
it would cost you some time and an additional 4 € ...
Please Note: I have never upgraded from A6 to A7 with this device via twrp,
you do this at your own risk ...

With B160, install firmware finder on your phone.
Add model as VNS-L31C432
Settings > Show firmware for this region only and Show full OTAs only.
Check firmware approval one or two times. (Make sure you've provided phone permission for firmware finder)
Get an update via DNS and it'll turn on vpn.
Check for updates and download.
I can help you on teamviewer if you still can't make it work.

I think that the firmware I need is the one that returns a 404 when trying to download. I've already done successful firmware approval several times for builds that won't install after all. Only the fact that it's such a mess to get updates for this device makes me really frustrated. What if I was a "dummy" owner of this device? I should never be able to get the updates I'm looking for. It's just impossible without doing too much effort or rooting the device. For me it's really important to have the original firmware of Huawei and not a custom rom, because I have to investigate the issue of my app user, which is device-specific. How complicated can it be to provide a solid update platform. Huawei, please.
I've decided to ship this piece of sh*t back to Amazon. Ordered a second hand Huawei P9 Lite that has already the build VNS-L31C432B418. Thank you guys for all the effort in trying to help me getting Nougat on this device, unfortunately it seems to be impossible.
