Manual system update failed - Asus ZenFone Max Pro M1 Questions & Answers

I just bought this device, it's on build 1901.339 oreo. I tried updating it to pie via the updater but it didn't show any update. I downloaded latest manual update file(1906.055) and started the manual update process, it started and booted into recovery, after a little progress it said error.
I tried downloading another package(1905.53)to bridge the gap between latest update and my version, same thing happens.
What's the solution guys?
I am very new to Asus, so My build number has 'WW' in it, that means it's SKU is 'WW' right!? and i downloaded the packages with 'WW' in their names.
So i think SKU mismatch isn't a issue here.
Thanks.

After 339 you must update to 340 sequentially for OTA updates. V340 is the last Oreo update

B330 no more available?

This is a bit weird. When I saw that B370 is rolling out in Germany, I tried update on phone to check if update is available. Now strangest thing is, that even B330 is not showing. I'm on B180 and about month ago I received notifications that B330 is available.
I even updated to B330, didn't liked it, rolledback to B180 and even after rollback i could update to B330. Now there is no update available. Even tried with HiSuite....but nothing.

I have the same issue! I don't know what is going on.
Now I found out that HiCare, when I started it, it asked me to update itself. So I did.
Now HiCare shows me OS early adoption update...something and when I press on it, it shows me that I can update to B370?
Weird huh? Even though regular updater doesn't show that there is an update.

Yes , it is really weird.
I find it out guys! Just unroot and you can install the update via OTA.
I didn't rooted phone
Sent from my Huawei Honor 7
Jesus , then i really don't know how to help you..
Have you tried manually updating the phone? Try to download the b330 and then update to b370.
I found out how regular update can be done.
Just applying thru HiCare and accepting new version B370, phone updater gained access and now it is able to update B370/
Sent from my Huawei Honor 7
HiCare needs to be updated normally.
Then when setup (region and user agreement) is done it should present a new update.
Full HiSuite backup is highly recommended.
If on B180, the update should have 1.19GB if on B330 should be around 400MB.
I´ve updated manually (got errors probably due to unroot and restock recovery image) from B180 to B330 then automatically to B370.
Factory reset, format microSD, full HiSuite restore and clean as a whistle.

Missing OTA updates

There have been 4 OTA updates, not including the Nougat update, since I last received one. The last update I received was in July (baseband version G930AUCU2APG1.) It isn't rooted but it's encrypted. It says everything is up to date when I check for updates on the phone. AT&T tried to push an update last night and they told me they were unable to contact my phone. I tried wiping it and checking for updates but that didn't work either. Is there a way to manually install these updates?

Download the Odin pk1 files and flash with odin. After that you should be able to take the nougat update. I'm not sure if you have to decrypt your phone though or not to Odin

EDIT: Tried installing using sd-card method and Firmware Finder but none of them work. Updater complains about illegal update and deletes the downloaded update.
Not working.
I downloaded full firmware 2.7gb not working dload method.
Also proxy not working.
Is possible FF to have a bug.
Is only 1 firmware for 3 phone.
I try other
I update with FF proxy
stop the download
Download the full update from http://pro-teammt.ru/firmware-database/?firmware_model=nem-l21c&firmware_page=0
Close the FF and proxy
Copy the update.zip in HwOUC
AND start the update.
Download the other 2 zip files update_data_full_public and update_ful_NEM-L21_HW_EU
Error this is unauthorized update
It's too early to update, you need to wait up to 2 weeks for it to be authorized
other update
NEM-L21C432B356
imposible to install
according to Firmware finder the update is authorized for installation but i didnt managed to install it. But i think it is because iam running Android 6 c100 version. Did anyone else tried to install it?
I have authorized for without imei.
Not working to install.
Maybe în fastboot.
New update 07.03.2018
other B300
New update
NEM-L21C432B357
If you have a look around the FF app you will see that they do actually make you aware that under emui4 there are no problems.
However they go on to inform you that you might experience bugs using the app under emui5....such as 'couldn't install', 'unauthorised', 'deleting the zip files...'. Basically the issues you have been experiencing. I manage to update to b360 selecting without wifi via proxy and it was essentially for a different region!?! But, hey it worked.
But like you even though there are newer updates I get the same problems now and the updated have been available for several weeks...
B361 and security patch is 1st MARCH!!
New update from 2018.04.28 :
NEM-L21C432B359
Integrates Google security patches released in May 2018 for improved system security.

You could update it manually through the asus website.
is yours original?
perhaps you should contact Asus team for query
Yet not received PIE update
I haven't received PIE update yet and it's already mid may.
Mine is also X01BDA, no update, Poland.
same problem as OP. Stock everything, India and never received PIE update.
Asus has posted pie update asus.com/Phone/ZenFone-Max-Pro-M2/HelpDesk_BIOS/
india version, officially has been release, try to update manually : IN__ZB630KL(ZB631KL)_16.2017.1903.064-20190420.zip
for FOTA, you have to wait more time

update it through the asus website. even i had issues with my FOTA update, when ever i went to my system updates it used to say its up-to-date and then after a while i got a notification saying FOTA stopped working or failed. I contacted the Asus customer support and they said to update it manually by downloading the file from the website. I just mainly wanted the update for the camera2api. Manually installing the updates works. I think the FOTA is bugged or something.
Heres the link
https://www.asus.com/in/Phone/Zenfone-Max-Pro-M2-ZB630KL/HelpDesk_BIOS/
go to the BIOS and Firmware tab and download the file named "Version WW-16.2017.1903.064". This is the indian variant.
transfer it to the internal storage of your device and unplug the device from your laptop. as soon as you unplug you should be getting a notification saying a new update has been found. click it. it will first verify and unpack the file before installing the update.
THE FILE SHOULD BE TRANSFERRED TO YOUR INTERNAL STORAGE, NOT YOUR SD CARD!!!
Hope this solves your issue!

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 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.

"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?

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...

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 ...

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...?

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.
