Ane-Lx3 update emui 9 [half resolved] - Huawei P20 Lite Questions & Answers

Hi, does anyone know how I can flash the base, curt and preload of the p20 lite ane-lx3?
I got them with hisuite proxy but they give me an error when verifying update.
I need it because I can only go back to emui 8 from hi suite emui 9 does not appear, I had downloaded it to unlock the bootloader. I already unlocked them but I want to go back to the most updated emui or at least more than 9.1.0.142 since it still has the app drawer button.
I have seen that the multi tool 8 can be used to flash but I don't understand how to do it.

this can be done via modified TWRP, HuRupdater 0.4 or Multi-tool if you are running EMUI 9.1.
But these methods are risky when upgrading from 8.0 to 9.1 and are not recommended.
You can safely manually upgrade to 9.1 only by installing the service ROM using the dload method from the SD card.
What is your full build number? (settings > About phone).
Also check your vendor/country information via the Project Menu (*#*#2846579#*#*) and post the result.

Thank you for taking the time to respond, here I leave what you asked for. I would appreciate it if you could explain a little more how to do the process.

I thought you were currently on 8.0, sorry. So you can try the methods in my previous post.
For HuRupdater method use TWRP 3.2.1 "Gaguga edition".
Rename all three archives:
base -> update.zip
preload -> update_data_public.zip
cust -> update_all_hw.zip
It works on the P20 Pro, it should also work on the P20 Lite. Be aware that these methods are risky, especially when it comes to choosing the right firmware for your phone!
Personally, I prefer an update via eRecovery & wi-fi, or installing a service ROM via dload.

The dload process will erase all your data and lock your BL again!

Good brief update: I tried all the stock roms of ane-l23 all with the same result in the case of emui 9 it stays at 9.1.0.046 and in emui 8 8.0.0.046 so far everything is fine after reading several forums here I have found one to see the files with root everything is fine up to here I enter /cust/hw and find two folders (la or latam) and normal. and in special cust only after all the props are fine, that is, it is 5.0.0.20.
Then looking for more information to see where the 8.0.0.046 was, I found it in version.prop. Additionally, enter splash2/cust.log and throw a lot of errors in the following post or answer. I leave you the images to see if we can solve something because the problem that bothers me is not being in emui 8 or 9 but that it is not so stable all that works if when installing any firm again the huawei id does not work first playstore and update hsm core after that everything works either themes etc etc.
but it lags a lot in emui 8 and in emui 9 google maps doesn't work so I don't care if I stay in emui 8 or 9 honestly but I do want the equipment to work correctly. Thank you very much for your willingness and willingness to help.

It means wrong or incomplete FW. As I said before,

Maybe you are doing something wrong...Follow instructions in ReleaseDoc folder.

you can only install the service ROM for your region (hw/la)!
But it is possible that with your current build number 9.1.0.046 you will not be able to flash via dload or eRecovery.

Yes I understand that, but what I wanted to say is that I already tried all the c605 firmware that there is, whether it is emui 8 and emui 9, they all install without error but apparently they do not install at all, I don't know if it is cust the oem partition or something like that but whatever the method, it always ends in .046 the only thing I know for sure is that it started to be like that a year ago when I used hisuite to go back and from there I could no longer update after what happened with hisuite I bought the code in dc to unlock the bootloader but I still can't remove the .046 in a few words hisuite screwed my phone xD because it was never rooted or unlocked until after what I told you

Okay, I don't know what the problem is, two last tips from me:
A) follow this method
https://ministryofsolutions.com/202...re-stock-rom-emui9-1-unlocked-bootloader.html
(reliable source)
B) rebrand to global version C432. But this requires downgrading to Oreo, and this is only possible through HiSuite (because there are no files needed for HuRupdater). It could help to get a fully working phone.

---

It could happen that before using hisuite you had a different region, not hw/la (claro/la etc.) hisuite couldn't recognize it and downgraded your phone to hw/la. Maybe you should try flashing oeminfo C605.
In fastboot mode run commands :
fastboot getvar vendorcountry
fastboot oem oeminforead-CUSTOM_VERSION
fastboot oem oeminforead-SYSTEM_VERSION
and post the result.

If you decide to rebrand, I will give you instructions.

If that helps me, ok, I tried option a) it was installed but it is incomplete with the pink background. If doing a rebrand will help me, ok

Now try to flash Service ROM.
Also try enter eRecovery and use option "Download latest version...".
As for rebrand, I can't give you any guarantee.

I think I achieved it in a while I'll tell you what happened but I'm hopeful something changed with the hisuite proxy

Ok, let me tell you, I managed to install firmware 9.1.0.355. I know it's not the latest and it didn't free me from system component 9.1.0.040 either, but at least now everything works correctly.
I'll tell you what I did in case it helps someone else:
1- I did the point a) that you sent me
2- I kept the pink wallpaper and I went to the proxy hisuite and downloaded the cust, preload and base .355
3- it marked an error when installing in the 1% of hisuite the proxy already warned me that it was going to fail and to cancel
4- cancel it and deactivate the 3 checks of point, cust and preload
5-I put in developer mode and look for the update in hisuite
6- This time I no longer throw any errors and it was completely flashed. I imagine that because of step a) the cust was updated and that is why it allowed the .355 to be installed
7-it was still half incomplete but I went into settings and updated and I got the same .355 version and it was installed correctly in quotes as I said I still have the .40 system but everything works now I imagine that if you keep messing around a bit that way it will I could install the .390 but I'm satisfied with the .355
