Me too. Roolbak erreur
You have to download the rollback package from huawei support, install the update.app from the rollback with the 3 button method, it's around 100mb, or so. Then download the marshmellow firmware, install it with 3 button, then you will have 6.0. You probably won't have the themes, it can be solved with twrp, and flashing the eu (or the region of yours) cust package.
I did that , and now I have c900b170. everything works ok except themes .
if I install EVA-L09C432B136 through dload method, should everything work ok? I will be able to get later the ota nougat update?

"Software Install Failed" When updating P9 Plus to L29C636B362

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.

Where can I download EVA-L19C636B381? (Solved)

I did a rollback to EVA-L19C636B190 and after the rollback there was an update. I didn't download it yet and proceeded to allow the oem unlocking first and now it wont OTA update anymore. I'll do the manual update so if you have the files please share! if you have another method to make OTA work please tell me. Thanks in advance!
UPDATE: I somehow got the OTA when my dload failed. I found a update pack that for C636 and it failed to install but afterwards I could do the OTA coz it reset my whole system I think

failed to reload stock EMUI 5 after trying to root

hi i bought a l09 years ago and tried to root it and use custom firmware
this was not the succes i was counting on, so i rolled back a update.app
this worked fine but i kinda screwed it up, first i had emui 5.0 on it

i don't know how i did it or what my original software was but i can't find any update.app that will update it to 5.0 without an error
if any of you know how i can roll a 5.0 or higher on my phone i would cherish you always

b182 - this is not complete build name
Look into Settings / About and provide the full name/number of your build, like EVA-L09c900b182 or so
If your cust is c900 (as in my example), there are will be no updates
You must rebrand to c432 tpo get Nougat updates

Current Firmware Update Method for Unlocked Rooted CLT-L09 9.1.0.328

Hi,
What is the current working method to update firmware on an unlocked rooted CLT-L09?
I would like to keep root and unlocked.
It's currently on 9.1.0.328. I see there are 9.1.0.388 and 10.0.0.157 available. Are there any negative consequences of updating to 10?
Apologies if this has been answered before but there are too many methods posted over various time for various versions it is hard to decipher which is the latest working version for my situation.
Thank you!

Download from FF and extract the original recovery from 9.1.0.328 and flash it. Now you're back on stock/unlocked. check the OTA updates. and after the update apply magisk again and you will be rooted on the last version. The procedure is the same to continue updating. Android 10 isn't ready for P20 pro, neither is root.

I've got the 328 update_full_base.zip but how do I extract the original recovery? The only img file inside is ptable.img
Sorry if this is a dumb question haven't flashed the phone in a while.
there is an app called huawei extractor. i'ts here on XDA. Disable checksum verify if gives an error while trying to extract.
