Hello,

Do you had to check roolback OS?

I leave Normal OS and my data partition was corrupted after downgrade from 162 to 161... I had to format data, so...
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
CLT-L04 C792 10.0.0.161 v401360
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
No but like you I had to do a low-level factory reset. (thanks to my backup..)

To do a rollback you need a specific version of the OS. This is not the case with what we have done.

So what packages should I use without problems on my CLT-L09 9.1.0.372 (C782E12R1P11)?

I'm confused...
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
It's late in the morning here and I'm going to sleep. I will do another scan in search of the CUST and PRELOAD for

your CLT-L09 C782. Nowhere to be found at the moment.

You can try with C432 but it's on your back. Not sure that your device will be certified. Also I have many

others packages to add on the first page.

Best regards.

hello, i have emui 10 and i noticed a rather strange bug ... when i pull down the notification bar quickly, strange colors appear at the top of the bar .. this does not happen if i pull down the notification bar slowly. happens to someone else of you ??
[Huawei P20 Pro Guides, News, & Discussion] mrbubba999:
Which is the best one to use for a UK P20 Pro?

I used this one from the French instructions, but I now cannot use Contactless payment as its not a certified version

My phone is a CLT-L09, all these different versions, I'm not sure which one from the 1st post to use (foolishly didn't do a backup either)
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
When you say UK, what revision ? C432 ? I will do a new scan for the CLT-L09 C782 tonight.

You used the .159 build ?
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
What version of EMUI 10, what is the build you used ? (I don't see this on my phone at all)
[Huawei P20 Pro Guides, News, & Discussion] MatthewLaw:
model : CLT-L09

build number : 10.0.0.161(C432E3patch01)

emui version : 10.0.0

android version : 10
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
Could be hardware related hard to say. Maybe do a post regarding your C432 and if you are alone with this problem, you know the reason.

Because here: https://drive.google.com/file/d/1-o_GzEp8bhokB1IWDk-gvdmlCXyE08wu/view

Try recording (screen recorder like I have done with this simple video) if you don't see the patterns you are talking on the vid, it's hardware related.
[Huawei P20 Pro Guides, News, & Discussion] MatthewLaw:
how can i send you a video to show you the bug??
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
Here I used Google Drive, when you go in galleries (pictures/videos) use the share option and google drive.

Then you have to go on your video in Google Drive and make it public.

Next share the link. (ex: email it to you, or if you use the xda apps, past it on here)

Edit: If you are talking about how to video capture on your phone, two options, from the shortcuts

in the quick access menu or by pressing and holding the power button and the volume up key simultaneously.

Best regards.

This Is the bug...
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
The colors on the bottom ? It's your icons. Not a bug, Put a different wallpaper and you will see.

The blurry effect is normal.

Edit: Ok now I see it, the blue color at the top ? Try with a different wallpaper again.
[Huawei P20 Pro Guides, News, & Discussion] MatthewLaw:
how does it be normal if when i pull down the notification panel slowly it only shows a uniform color, while if i pull it down quickly it shows other nonsense colors (Blue) ?? in the video you can clearly see the difference
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
Yeah I understand what you mean. But try with a different wallpaper.

It's just a software bug. What vxxxxx of emui 10 you used ? Here I'm on the last one: v401360

There is at least seven builds regarding 10.0.0.161 now.
[Huawei P20 Pro Guides, News, & Discussion] MatthewLaw:
I'm on V.400515

How can i use the last version?

how do i update the version?
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
I added all of the 10.0.0.161 builds on the first page. To "update" just use the BASE package (Package URL) with Hisuite Proxy/Hisuite nothing more.

See: https://xdaforums.com/showpost.php?p=82924317&postcount=250

---------- Post added at 02:29 AM ---------- Previous post was at 02:23 AM ----------

I am already in emui 10, I would just like to update it to the last base ... I repeat the same procedure that I did to update it with I have suite proxy to emui 10? but this time with the last base (401960) and not the first (400515)
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
I know but they are different all of them. Yes you unmark cust/preload and only use the base package (Package URL) and mark point version to CLT-LGRP2-OVS 10.0.0.161

Hisuite will tell you that an update is present.
[Huawei P20 Pro Guides, News, & Discussion] MatthewLaw:
doing the procedure I had to insert the cust and preload again (I put them the same as before) and then I changed the base, putting the new one ... is it ok anyway ??
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
You don't need to put any CUST or PRELOAD package. Only the Package URL (base)

Edit: Zero need to put the same PRELOAD and CUST package, you are already using them.
[Huawei P20 Pro Guides, News, & Discussion] MatthewLaw:
thank you so much for your help, very kind.

one last thing, is it better to do a factory reset after updating it to the new version? to avoid bugs
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
It's still better to do one, like me the last time I made a factory reset it was with android 8.1. So when I upgraded to 10.0

It was the good timing to make a factory reset. You can still backup all of your data with Hisuite.

With Android 10 there is many changes in the permissions regarding the apps so., to me it was a good idea.

[Huawei P20 Pro Guides, News, & Discussion] mrbubba999:
The screen shot is what I have on my phone right now.

The photo is from my partners phone (she got the official OTA but hers is dual sim)

I don't know what C432 and C782 mean?
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
This is related to your "region".

Ex: C69 is Mexico

C792 is Canada

C432 is Europe

C00 China etc.

The list is large..

Then you have a model version ex: CLT-XXX

Depending of your device you need to use the right PRELOAD and CUST package to upgrade. (EMUI 10)

It's more about having a certified device. Yeah I know it's stupid but it's Huawei.

I see CLT-AL00 on the left, it's china. Did you upgraded using a preload/cust with Hisuite Proxy or it's your real revision ?

Edit: Ok you used that french guide.. Go into the settings and about your phone. Check the model version. But we still need your real region. CXXX

So, UK, single sim, it's a CLT-L09 C782 probably ?

Next time, don't post the IMEI of your girlfriend device...
[Huawei P20 Pro Guides, News, & Discussion] MatthewLaw:
unfortunately even changing the base with the last one the bug reappears ...??
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
Make a thread and ask others if they have the same problem with the same model of your phone.

Can't really help you on that.

Best regards.
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
This place is turning into a joke sometimes. IF you don't even know what your phone is, please for everyone else.. Ask before doing any stupid ****.

Don't follow this stupid guide on the Huawei forum. It's outdated.

This is my last sentence, I'm going to sleep.

Best regards.
[Huawei P20 Pro Guides, News, & Discussion] mrbubba999:
You're right, its a C782, but surely I could use a C432? as thats certified. The issue I have now, is that no matter what I put in the Hisuite proxy, my Hisuite app always tells me I'm running the most up to date version. I only found out about Hisuite proxy yesterday evening, so knowledge is very limited on it.

The screen shot shows what I get from Hisuite when trying to update and the 2nd one is just me trying to change the Hisuite proxy (I'm probably filling in the options wrong) It's been quite a few years since I messed around with flashing anything on a phone (not since my Oneplus 3T)

If I can just get it on an EMUI 10 version, which allows me to use Google Pay, I would be very greatful :)

I know what my phone is, but wasn't aware of what the different codes meant. My phone is a C782, which from my research is usually lacking in updates from Huawei (or at least very slow). My partner has an EU import (bought on Ebay) and her's is a C432 and she always gets more updates on hers than mine.
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:

Amazing how that worked for me the first time round :laugh:

It seems to be updating now, I will see how it goes on my snail speed broadband

thanks for the help :good:
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
Also you don't need to put vxxxxxxx at the end in the point version case.

The version is

CLT-LGRP2-OVS 10.0.0.161
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
Don't know if your goal is to have a certified device or not but you will still end with CLT-AL00.

I've done many scans in search of the C782 PRELOAD/CUST and nothing. I will probably start a new one before I go to my bed.

If I was you, i'd go with the CUST and PRELOAD for the C432. Still better that a Chinese cust.

Note: Even if you stop the update and add the packages, it will resume back to where it was.

Best regards.
[Huawei P20 Pro Guides, News, & Discussion] mrbubba999:
I may have missed something here. I updated to .161 but my phone build is still showing as CLT-AL00 10.0.0.161 (C00E156)

Obviously this fails the tests as its not certified. How do I get to the right one for my region, so that it passes the test and I can use Google Pay?

I'm just trying again with the following options in the screenshot

Edit - I didn't tick the CUST Pkg and Preload PKG

could that be why I still end up with CLT-AL00 ??
[Huawei P20 Pro Guides, News, & Discussion] mrbubba999:
Yes certified is what I want to end up with. I'm hoping with what I have selected now, I will end up with CUST and PRELOAD from C432
[Huawei P20 Pro Guides, News, & Discussion] hr2974:
Okay thaks, good to know..

My backup was 2 weeks old.

I will backup all before do everything in the future.
[Huawei P20 Pro Guides, News, & Discussion] fbriere56:
Yes. This is exactly why. Next time I will explain more about theses. (PRELOAD/CUST)

I extracted many of the PRELOAD and CUST package just to see what is in them, most of the scrap I saw was related to: apk (apps for a carrier, etc)

images, icons, etc.

That will be my last post for today. I'm going to bed, a scan in the background for your C782 on my left computer.

I'm done and drunk. See you later.

You can change the PRELOAD and CUST like you want with Hisuite Proxy.

You don't even need to use a base package to change them if you are already on EMUI 10.

Now the list have most of the important model of the CLT-XXX so this page won't get updated any more.

Well, if you need a version just ask and I will find your packages.
