Update from B135 to B380 directly, is it ok? - Huawei P9 Questions & Answers

Hello there, I'm trying to update my EVA-L09C605B135 to B380 (nougat) manually and I want to know if it is safe to do it. In Fimrware Finder I found aviable only B320, B360 and B380 and previous only B135 (the one and latest I'm currently using) for my CUST. Should I start by updating to a previous version or is it ok to go on with latest?
Edit: in FF B320 and B380 appear like "OTA" while B360 is the only that appears as "FULL", what does that mean? Should I go for FULL?

I have a Vodafone UK branded handset and went from B137 (MM) to B341 (Nougat) without any issues.
I had TWRP installed and flashed the update zips there, when i went to Nougat and temp lost TWRP, using the dload folder method worked too.
tl;dr - yes to your first question! IMHO.
I would say that ota updates are incremental updates, and if coming from one android version to another ie Marshmallow to Nougat you want to flash the "full" update zip. That's what i would do anyway...
Peace

Am also in need of that answer.

How can i Install Lollipop From B126

Hey guys!, happy to see you guys around and i hope you can help me with my case.
I've a Huawei P7 L10 European Version(i believe) and i wanted to install Emui 3.0(Lollipop 5.1.1 Oficial), but i wanted to know if i needed any other version from my B126, because i downloaded Lollipop (B852) but it always pop FAILED after i do Local Update.
Is there a way to install Lollipop on my phone? do i've to have an specific version? also the phone says unlocked bootloader but i cant install any recovery.
Thanks!
You need to install B133SP01, then B609, and I believe it will be possible to do an upgrade to B85x based on Lollipop.

Should i install it via Local Update? B133SP01 then B609 then B5x? What about any FOTA update?
PD: Which version of B5X based on lollipop do you have or recommend?
I've checked this for you and this is the correct way to get Lollipop if you're on stock B126:
-Install full B133SP01 via local update
-Install full B609 via local update
-Install B623 (i've had an auto update from B609 at this point)
-Install B830 via the local update (it's Lollipop, incremental upgrade from B623) link: http://www.carbontesla.com/2015/10/download-ascend-p7-b830-android-5-1-1-lollipop-ota/
-Install B839 (major fixes) link: http://www.carbontesla.com/2015/11/download-ascend-p7-b839-lollipop-ota-zip-video-fix/
-and finally choose a B85x for yourself, I have't used one yet so can't recommend anything.
Edit: I did actually install B852 in the morning, works fine - good build
Incremental upgrade from B839 can be downloaded from here: http://www.carbontesla.com/2015/12/download-huawei-ascend-p7-b852-lollipop-ota-zip/

Unable to install stock rom Huawei P9

Hello!
I'm currently running on EMUI 4.1.1 (EVA-L09C900B182)
I downloaded the official firmware for P9 from Huawei website, extracted the UPDATE.APP with this tool https://forum.xda-developers.com/showthread.php?t=2433454 so i could get the stock RECOVERY.img.
I placed the UPDATE.APP in a dload folder on the root of my external SDCARD
Rebooted into bootloader, flashed the stock recovery (I had TWRP).
vol+, vol- and power button togheter, it tries to install but fails (software install failed! Incompatibility with current version. Please download the correct update package.)
I tried also with huawei firmware finder app and even if it says the firmware is approved for the installation when i verify with IMEI, it fails after (I tried EVA-L09C900B386).
I tried:
- with the in-app proxy, changing my wifi proxy to localhost:8080 and using the default updater
- downloading the package and manually moving UPDATE.APP in dload on my ext sd card.
What i would like to obtain is a full stock huawei p9 phone, so i could get the official android 7 and latest firmware.
Thanks a lot!

Best is to follow this guide and debrand the phone to C432.

U have to downgrade to B182 and then upgrade to B360 FullOTA-MF-PV
When u upgrade to a new Android system u must flash FullOTA-MF-PV
U could try without downgrade first, but u cant upgrade to B397 because its not signed yet by Huawei, B395 ist the latest approved Firmware.

From b182 OTAs will lead up to b395.
b397 OTA is expected any day, meanwhile it can be forced (as well as the newer b398) from b395 by using no-check recovery:

What country/region are you from?
What is the present firmware version B160 dated?
Firmware Finder (FF) (online version) shows B150 as the latest, so FF's probably not going to help you unfortunately: http://pro-teammt.ru/firmware-database/?firmware_model=VIE-L09c627&firmware_page=0
Your only other option may be to convert to another region's ROM, which has received regular updates - e.g. Euro C432 ROM (latest is B382, dated March 2018). But, it's a risky procedure which involves unlocking the bootloader, rooting the phone, changing the vendor country info with SRK Tool, etc, etc.

Which update did you try? If you're still on 4.1, then you should try a much earlier update (i.e. the very 1st 5.0 update) - I'd recommend one of the B361s from here (or via the FF app): http://pro-teammt.ru/firmware-database/?firmware_model=VIE-L29C605&firmware_page=0
Always download & apply the FullOTA-MF, in this case ~1.3Gb file size.
Once you have installed B361 successfully, try the B381 update (not the latest B382 as it will not work at this stage most likely). Again, download the FullOTA-MF (1.4Gb) & apply it.

I tried all of the full OTA on FF all them download just fine but every time the phone restarts to install the update for some reason it fails at 1% of the install.

try B202 first
I had an P9+ B130 version and was able to upgrade to B202, which is needed as a stepping stone to MIUI 5. I used FF with the proxy update scheme. The B202 update worked while other versions stopped at verifying the update, which is just what you experienced.

I'm out of luck then it seems that the B354 update is no longer available on FF which is the "steppingstone" in my case.

Version downgrade

I have searched everywhere but I didn't find a reply to my question.
A couple of days ago I have updated my phone LLD-L31 to the version 8.0.0.132 through Firmware Finder (it worked for me with proxy method) then I decided to revert back to the previous version 8.0.0.131. So I started reading guides to install a firmware on Huawei/Honor devices, I have downloaded the FullOTA package version 8.0.0.131 with Firmware Finder, placed it in the folder dload on my SDcard and started the intstallation in the project menu (accessible digiting *#*#2846579#*#* in the dialer), it started but suddenly it ended with a message "installation failed".
So my question is: how can i revert to the previous version of the software (or to the out of the box firmware installed on my device)?

You should have an option to downgrade in the about section/ the update menu of your phone if you did it right.
Otherwise you may need to use the HuRupdater Method.

Thanks for your reply!
I don't have this option, but if I remember well I hadn't it also in the previous version of the firmware.
So i can't install a previous version of the firmware simply downloading it an putting into dload folder of the SDcard?

Can you please specify why do you want to roll back?
Because most people just wanna upgrade to a newer version.Newwr versions will have better stability so it's recommended to keep the latest version unless you have some bugs.
I honestly don't know why the dload method doesn't work, seems that it doesn't work for most people.
I think you'll be able to roll back using HuRupdater. But that'll mean you'll have to unlock bootloader and flash twrp first. Then you can go all stock from there.
Here's a guide to the HuRupdater from @zxz0O0

After installing the version 132 I asked the technical support through HiCare and they told me that installing firmware with Firmware Finder could void warranty so I decided to revert to the previous firmware and wait for regular OTA by Huawei.

I'm not sure but I think you are on the latest build for your varient now so you won't be getting any updates untill a next build comes in.
I don't think you'll be able to roll back without the firmwares from firmware finder as you don't have an option to roll back.
The best option now would be to just wait for the next official build(might come soon as a small ota which has security patches) and then check if you are facing any issues installing which you won't as you are not rooted and dosent have an unlocked bootloader. So don't worry ?

Downgrading version Problem
I used firmware finder and dns method to downgrade my honor 9 lite and while i register update on firware finder and opens hisuite for update it is saying u r on already the latest version
Plz help me with downgrading my version 9 to 8

Can't update my P9

My P9 is currently running Nougat and I want to update to Oreo but in "About phone" it says I'm running Android 5.1 and EMUI 3.1 (I'm 99% sure I'm running Nougat). My phone is second hand and I've never rooted it but the last owner might've (if so then it got unrooted before it was sold). I have 4 months left on my warranty if it matters. Whenever I put update.app into a dload folder on my SD card I get an error at 5% when trying to update saying "Software install failed, Incompatibility with current version. Please download the correct update package." I use Firmware Finder to find the latest update and in "About phone" it says my build number is "EMUI-A168-L09C432B040SP11-log" so that's what version of updates I download. I don't get any OTA updates and Firmware Finder's DNC and proxy method don't work for me either. When downloading Nougat I did it manually (through dload) and I think it was some sort of beta or leaked version or something. I don't know what else to try but I just want Oreo on my phone. My bootloader isn't unlocked and my phone is definitely not rooted. I live in the UK so my phone is most likely from there too. What should I do or try?
Edit: I just tried updating my phone through Firmware Finder using the proxy but I get a package checksum error when I try
"Android 5.1 ... 99% Nougat" - Can you post the screenshot of your Settings/About (mask your IMEI) to see what are really your EMUI and Android versions. Also, scrolling down in About should show date (month, year) of the Google security patch - usually it means that Huawei built the ROM the same or next month.
You can also install from Google Play apps like My Device or DevCheck to see if they recognize it as Nougat
Googling for emui-a168-l09c432b040sp11-log finds that it was some early beta version (June 2016) for Android N, see eg (Chrome can automatically translate from Hungarian to English)
https://huaweiblog.hu/tag/emui-a168-l09c432b040sp11-log/
Frankly, I don't believe the phone under warranty was released with beta Nougat, rather that previous owner installed the beta (also I don't know is the phone covered by warranty with that beta N).
Look also to XDA, thread
https://forum.xda-developers.com/showpost.php?p=67931734&postcount=62
subsequent posts, how people who installed beta N (c432 cust or other custs like c900) went back to their official Marshmallow (or upgraded to official Nougat).
"tried updating my phone through Firmware Finder" - I don't find anything at all on Firmware Finder for EMUI-A168.
IMO, you cannot 'update' from your EMUI-A168-L09C432 to the regular EVA-L09C432 (good that it didn't brick your phone). Generally, going from one model/cust to another requires rebranding which is a whole different process, not just taking whatever ZIPs from Finder Finder and flashing them by DLOAD or by DNS/proxy in FF.
IMO, you must go back from your Beta N to official MM (from that time). Then (if it was EVA-L09C432) you will receive OTA updates to official N, or if necessary you will need to rebrand to eg c432 (since some other custs, like English Vodafone, got stuck at MM, there are no N builds for them).
Of course, rebranding (it voids the warranty), if necessary, requires to unlock the Bootloader.
Finally, Oreo is available only for Chinese cust, not even for European c432, and it requires (unlocking Bootloader and) HWOTA7 method, but for that you must first get rid of your Beta N (even rebrand if necessary - see above) to be able to start the HWOTA7 process towards the Chinese Oreo from some of the latest official Nougat builds, see
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
I'm not sure if HWOTA7 (that can be also used for updating Nougat builds ans rebranding from one Nougat cust to another) is applicable to your Beta N.

It's probably not even neccessary, it is already c432, it should be enough to flash c432 b182 by DLOADvto come back to c432 MM, and then OTA updates will bring him to the latest c432 b50x Nougat - no unlocking bootliader needed
To the other side HWOTA7 might be risky as it requires EMUI 5 and it's not sure is it there in that early Nougat beta build

HWOTA7 directly from that b040sp11 might be risky as HWOTA7 requires pure EMUI 5 and it's not sure is it there in that early Nougat beta build - therefore going back to MM c432 b182 is betrer (google, you will find people from that time doing so from that Nougat beta)
Once at b182, OTA will bring him to the latest c432 Nougat (his warranty will be back) and then if he wants he can unlock bootliader and use HWOTA7 to go to Oreo (without warranty anymore)
Here you find EVA-L09c432b182 and how to flash it
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
Only the following steps apply for you:
2, 11, 12, 13, 14, 15
With the small modification for step (11):
- ignore the first sentence "Go back to main menu and reboot your phone - but not to system. " since you are not coming here from TWRP
- instead, switch the phone off and then boot as in the second sentence "You must press Vol+ and Vol- (in the middle) down until EMUI Software Installing begin and b182 will flashed" and continue with the rest
Upon the OTAs as in step (15), you will have official c432 Nougat (and your warranty)
Later, it's up to you if you want to unlock Bootloader (4 Euros needed for the Bootloader code) and to upgrade to Oreo by use of HWOTA7 method
