"Software Install Failed" When updating P9 Plus to L29C636B362 - Huawei P9 Plus Questions & Answers

Hello!
I have a P9 Plus that I wish to update from Marshmallow (L29C636B170) to Nougat (L29C636B362), but I am unable to because I keep on getting this message when I try to update...
http://i.imgur.com/2m7sV4I.jpg
"Software Install Failed!
Failed to check the update package.
Please download the package again".
I have tried using different firmware versions like B320 but the same error appears.
This phone used to have a custom TWRP recovery, but was returned to stock, and I fully unrooted my phone. I then use the Huawei Updater to send the package to HiSuite and find the firmware using Firmware Finder. I still have an unlocked bootloader however. Am I missing anything?
Cheers,

Try relock the bootloader.

How do I relock the bootloader? I tried using fastboot oem lock to relock but it says that the command isnt allowed.

just simply force update dload of update.app if you are in B170 then use update.app of B170 and force dload by push 3 button same time

Okay, it seems I have solved this question with the help of Mostar088 and itongx. Special thanks to them!
The first problem was that the firmware I had was to old to update to Nougat. I had to install L29C636B202 using HiSuite. This updates the firmware to B202. Updating to B202 makes it capable of upgrading to Nougat. So, I then install L29C636B370 to my phone using HiSuite and Huawei Updater. So far, I'm loving the update and none of my files were deleted, however, this doesn't mean you shouldn't back up.
Cheers.

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.

I did something similar and ended up with C432B242 after some update with huawei firmware finder. Now I cant reach B397.. I've tried all the intermediate steps after 242: no luck. It fails during installation. Any specific instruction?

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:
https://forum.xda-developers.com/p9/development/eva-nocheck-recovery-flash-unapproved-t3705125
Update:
I reinstalled from b136 => b166 => b182
After that i tried b378 but now my build number is NRD90M test-keys
Will start again from b136 trying something different.

Mate 10 Pro Unable to update firmware OTA or using eRecovery / FunkyHuawei

Hi
I'm unable to change the firmware on my BLA-L29 C432 B142 May security patch (rebranded from C636 about 6 months ago).
Checking OTA just says 'no updates available' and if I try to update via FunkyHuawei using eRecovery it downloads but after 'verifying' it moves on to 'recovery system running' and then errors with the message 'recovery failed' when it gets to 1%.
I've tried quite a few things to try and get something to move on, but it seems like I'm stuck on an old version of firmware and no way to change it. I need a new plan.
I've tried (with lots of factory resets and wiping cache inbetween):
- OTA updates - always says no update available.
- Via FunkyHuawei:
- Reflash same firmware (eRecovery fails during 'recovery system running')
- Reflash newer or older firmare in same region (eRecovery fails during 'recovery system running')
- Change region, reflash newer or older firmware in same region (eRecovery fails during 'recovery system running')
- Use unbrick tool to flash same or different firmware in both same and different regions (unbrick tool completes but firmware version always stays the same in about phone, the android security patch date changes though, but eRecovery won't let me reflash anything afterwards as eRecovery fails during 'recovery system running')
- The last OTA update I got was C432 .137. When everyone else was getting .145 OTA I got Firmware Finder to move me from .137 to .142.
Has anyone got any ideas on what to do next? I don't want to be stuck on the same firmware version and security patch forever.
Other than the FunkyHuawei rebrand about 6 months ago from C636 to C432, the phone is standard (no attempt to unlock bootloader, root).
I was thinking of:
- Unlock bootloader using DC unlocker (from what I've read this might still work as I'm on B142 which has a May security patch)
- Flash TWRP
- Flash a custom ROM
- Try and restore back to stock
- Possibly rebrand back to factory original C636 as there seem to be a few threads about rebranded phones not getting updates promptly, but I can't see anyone else who is getting eRecovery failing no matter what they do and no way to change firmware. I have already tried rebranding back to C636 via FH, but can't, as eRecovery fails at the same point when trying to flash the C636 firmware.
Funky should always work to update, check that DNS is correct when you enter that test site.

This will work. I have downgraded and tested it
You could do this:
Get unlock code
Unlock bootloader
Flash TWRP (https://forum.xda-developers.com/mate-10/development/huawei-mate-10-pro-twrp-3-2-1-0-t3769904)
Download firmware update.zip, public and hw zip from http://pro-teammt.ru/firmware-database/
Update to the version you want using HuRUpdater (https://forum.xda-developers.com/honor-9/development/tool-flash-official-firmware-recovery-t3769279).
You will stay bootloader unlocked now though, but the rest is stock.

The DNS is fine and I can load the test sites, eRecovery gets info and downloads the firmware labelled "FunkyHuawei" and the size is around 3GB. After taking a few minutes to download, the eRecovery moved on to 'verifying package', that completes, it moves on to 'recovery system running' and after it gets to 1% it says 'recovery failed'.

I will try this, anything to get me out of the hole I seem to be stuck in as all methods I've tried so far rely on eRecovery. Thankyou for all of the links.
When using HuRUpdater does it have to be in the same region, or can I rebrand at the same time?

HuRUpdater can only handle same region updates as far as I know.
You can use HWOTA to rebrand, but mankindtw (original author) has since edited the thread as he thought his tool bricked devices. But it was firmware that caused it.
And I can't remember the exact steps... You have to flash twice though, first to rebrand (example C636) and then to update to the same rebranded (C636) firmware.
https://mega.nz/#!oeATEQQb!qiP3mYlQQgZYlaS3dbY_QCwNJ-urTKyLQ2zKOA9KP8g
You could use FHRebrand tool, but it will change your bootloader unlock code so you'd have to use HCU client (DC-unlocker) twice to get it.
Also, before flashing anything, check xloader with this tool: https://forum.xda-developers.com/mate-10/how-to/beware-bla-l29c432b147-t3817241
For now, stay on XLOADER 01 firmware. We don't know if Huawei will change to 02. Going from 02 to 01 will end in a hard brick.
B142 is 01 so you're safe now
Thanks to your advice, I have a plan now. And good to know about the xloader stuff, that could have ruined my day.
I'm going to:
1. Get bootloader code [update: done using dc-unlocker, confirmed working on C432 .142]
2. Flash TWRP
3. Put same region and slightly downgraded version of firmware on to a USB and flash with HuRUpdater (assuming it needs to be put on a USB OTG stick as the M10Pro doesn't have an SD card). I intend to use the downgraded version so I can see the version successfully change in "about phone"
4. Rebrand using FH tool (if there's less chance of bricking than HWOTA) and keeping an older firmware
5. Hopefully it works, and [after getting the bootloader code again from dc-unlocker in case I need it in future] I will be able to update via OTA to latest official firmware
Hopefully starting again completely will overwrite whatever it is that's getting me stuck.
Thanks to @ante0 I got out of the hole I was in.
From what I've tested, there seems to be an inability to update OTA from a rebranded BLA-L29 432 running 137 or 142.
Here's what I did.
1. Unlocked bootloader, flashed twrp, flashed downgraded 137 version of C432 with hrupdater. Success. No offer of an OTA update though so still stuck on old version.
2. Ran FH rebrand tool to change region to the factory original C636. eRecovery failed at the same stage as before. Fail.
3. Kept region as C636, unlocked bootloader and flashed twrp again. Flashed April version of C636 firmware using hrupdater, twice. Success.
4. Immediately on boot up phone offered to update OTA to the latest version of C636 firmware. Success.
It seems that the phone wouldn't offer an update OTA if on rebranded C432 and running 137 or later, but did offer OTA when it was back on C636. I live in Europe, but will keep the 636 region if it means I get OTA, else I can't pass the phone on.
Now to relock the bootloader so banking apps work. Plan to use the fastboot relock command followed by dc unlocker relock tool. Hoping not to brick at the last stage!

Update EVA-L09C900B182

I have a Huawei P9 that doesn't seem to receive updates.
EMUI 4.1.1
Build: EVA-L09C900B182
Andriod: 6.0
I have tried using firmware finder but I always get checksum failed before it passes 1%.
I had a look through the Forums and it seems that people recommend rebranding though that was in 2017.
I was wondering if there is any easy way to update?
I am a noob so i want to try avoid rooting and rebranding if possible.
Has anyone managed to update this?
2 years later and I'm still trying...

For c900 there is no newer firmware.
Flashing anything else than c900 means rebranding - but rebranding requires unlocking Bootloader (not 'rooting')
So wandering, what are you really trying to do for two years?!
- Unlock Bootloader (4 Euros):
https://www.dc-unlocker.com/
- Rebrand properly to be able to update to Nougat eg EVA-L09c432b504:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
I followed that guide but now my phone is stuck on "Type the password to decrypt storage" when I enter my Google password it says it's correct but data on my phone is corrupted. Any ideas?

Are you talking about TWRP asking for pass or Android?
If Android, on which firmware are you, what was the last step you performed?
Also, make sure you used TWRP for MM, not for Nougat - since you were on c900 MM when you started with rebranding to c432 (?)
Btw, you unlocked the Bootloader?
Thanks for the quick response and all your assistance. I managed to finally boot into EVA-L09C432B182 and will write what I did in the rebranding post for others who run into this issue. I still have no updates on L09C432B182 though.

For OTA you must have a valid SIM card and WiFi - check manually to the System Update to trigger checking for an update
You can also try with HiSuite (PC) - latest versions of HiSuite have an option at the bottom to update the firmware
See:
https://huaweiflash.com/how-to-flash-huawei-stock-firmware-all-methods/
You can also update by DLOAD (read the guide above), you must download FullOTA-MF-PV (must be PV), like b360, from Firmware Finder
There is also HWOTA method, see:
