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

I updated from B136 to B839 via Local Update.
At 99% the Update aborted and the P7 said: update fail, cust fail
I tried a reset and here is the same: cust fail.
The B839 is working so far, but there are some bugs only I have.
I tried to downgrade to 4.4 via local update with the transitionpackage from Huawei, but the same:
Update fail.
Could anybody help me, please?

I had tons of problems because I also updated from B135 directly to B830. But downgrading back, installing the CUST fix and upgrading up again fixed it. Hope it helps.
Is there no way to easily flash the fitting CUST-Version for B852?

Unfortunately no, I don't think there is. B621 is the only I've ever seen.
I updated from B136 directly to B839 (Full) via Local Update and then to B852 (70MB-file) also Local Update.
So I have to downgrade to B830 first, then to B621?
CUST-Hotfix not needed?
After that I can upgrade to B839 with the Full-Version (local Update) without first upgrading to B830 and then to B852 with the update-file?
Do I have to handle it with Local Updates or are force Updates also possible?
Yeah, downgrade back to B621 (I had to go back in exact steps I used to go forward, meaning B839->B830->B621), install B621 CUST fix, install B830 and then you can either use full B839 to be sure like I did or you can go B830 -> B839 OTA -> B852 OTA (currently B852 only comes in OTA version).
Sometimes, if downgrading step fails, just keep repeating it. Eventually it will work. Not sure why this happens, but it does.
Ok, so my plan looks like this:
Unrooting my device by flashing Stock Recovery Emui3.1 via ADB
Factory Reset
Downgrading directly to B621 via Force Update
Factory Reset
Installing B621 CUST-Fix
Factory Reset
Update to B839 with Full B839 via Force Update
Factory Reset
Waiting for OTA B852, installing it OTA,
or
Local Update B852 (60MB)
Factory Reset
Flashing TWRP 2.8.7.0.img via ADB
Rooting with SU
Does this looks ok?
Something is going wrong.
Downgrade fails.
Both, Force Update and Local Update installation to B839 fails.
My device was rooted and the TWRP recovery was installed.
So I installed Stock Recovery EMUI3.1 in order to do the downgrade.
But there is no chance to get the downgrade to B839 work.
I also tried to downgrade to B830 but there is the same problem.
I tried several times.
What is wrong?
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.

Install b182 (still MM) and you should then receive OTA upgrades to b38x, b39x (Nougat)

I still don't understand why you don't 'like' OTAs. In System Update, Settings, you can always choose Full Update instead of default Differential. And you can force afterwards Factory Reset if you think you need.
b386 is the last flashable by DLOAD. Btw, I was going back and forth through diff stock and rooted and custom ROMs, rollbacks, OTAs, and never had any error in installations. There are many threads with excellent info and guides, you must read and follow because in diff situations methods might be different. DLOAD is not always applicable
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!
K
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.
Help, I want to update from MM to Nougat or Possible to Oreo. Help me please! I'll do whatever i can!
I already tried via Firmware updater and firmware finder. No luck. I tried all the OTAs. All failed!
Can somebody help me?
Did you copy file to sd card and tried updating from there?
SOLVED! Changed OEM Info
