Huawei 30p lite - Revert to EMUI 11 from EMUI 12 - Huawei P30 Questions & Answers

I searched a few hours in the internet to find a finite answer but there are so many old threads and old Youtube videos with dead links so I'm not really sure if there is a way or not.
A friend of mine has an Huawei p30 lite and wants to revert the last update back to the previous version of EMUI 11 instead of EMUI 12.
The phone is still on stock - no open bootloader, no root, nothing.
Is there any way to revert the last update back to Version 12 - best case without bootloader unlocking tools just be placing an older version of the firmware somewhere?
Sorry if this has been asked countless times but as I said I always only found dead links.
Thank you very much.

Huawei Mate 8 Update went wrong

hi, dear xda forumers!
this is my very first post, and i am not very good at tech things, so please bear with me (plus I may unwantingly commit grammatical mistakes because i am not a native speaker and it is 2AM here)
first my back story:
I had a Huawei Mate 8 (nxt-l29c....something) European version, I had it for about 6 or 7 months, then it was stolen. By that time it had automatically upgraded to Nougat and I really liked it, got used to it, could not live without it.... so i decided to buy the same phone again. It came with Marshmallow, and I tried to update it but the OTA had been for a limited time only I guess, I emailed around with official huawei customer service asked them maybe to update my device from their headquarters or something, but they could not help me, they said I should just wait and eventually it would update.
after 3 months still nothing I grew impatient and I really wanted to have my "old experience" back, so I tried a tutorial with updating via filmware finder, using one of the first updates that were about 2GB big. It was successful, so it seemed at first, because there were no errors or interruptions, but finally when I turned it on, I noticed that during the update process my phone has lost the built in keyboard (still has the google), no more bluetooth, alarm clock, date time settings, update option
I downloaded the official rollback to Android 6 from 7 but since I updated with an unofficial update, it failed to fix my phone. now I still have the issues listed above.
Now I ended up with
Model number: NXT-L29C900B500 (originally it was NXT-L29C432B180)
EMUI version: 5.0
Android version: 7.0
Edit:
Now trying to use a new filmware from the official huawei website with the dload method
Edit 2:
it did not do anything. I will try again when I wake up
I kindly ask anyone who has any idea how to fix this to reply.
Mate 8 nougat update as far as I know have 2 update zips, I've experienced that problem when trying to update to nougat, I used twrp to flash the update.zip, I had emui 5 after but Bluetooth didn't work and some settings were missing, after searching I found that there are 2 zips to an update, a update.zip and a hwupdate.zip, basically only one was installed for you, you need to install both

Mate 9 MHA-AL00 unlocking bootloader and emui 8

Hello,
1st i want to say, that I am not a phone expert. I got (I could not choose) this Mate 9 but how you already know it's chinese version. I was researching but after reading so many threads and websites I got tired and confused that I had to sing up for help. I would like to ask if there is a option how to unlock bootloader, because the officially way through Huawei website seems to be shut down. The link for registration for the unlock code does not work and I could not find any information about it on the huawei website. So is there any free way how to unlock it ? I want to change the region and get fully English rom. Another question is, I read on couple websites that AL00 should get the new EMUI 8, I have in the phone 5 and I am wondering how to upgrade to version 8. Again I found some info and files for download but boodloader has to be unlocked but on other side I saw something that it should be officially upgrade, so I will still need unlock bootloader ? If no, how can I make upgrade to emui 8 ? Current I have B186 and next new upgrade I have B233, I didn't download that one yet. Do I need some special build and after it will be installed will show up the upgrade to emui 8 ?
Thanks a lot for help.

Downgrade Android 6.0 to 5.1 in Honor 6 H60-L12

Hi, I have a problem with the phone, I installed Android 6.0 Emui 4.0.1 version H60-L12C00B860 but I need to do downgrade to Android 5.1. for rooting phone by Kingroot. I found only a file name H60-L02-L12_EMUI4.0_2_EMUI3.1.zip (283 MB) but I do not have Emui 4.0.2 ,I have 4.0.1. Will this file work correctly? And if not, what's easier to find: upgrading Emui to 4.0.2 or older downgrader for Emui 4.0.1. Please help. Sorry for my bad english.
//I found the right file, but there was a bigger problem: I do not have "local update" in the Emui update options - i can only update online. How can I restore/add this option?
No one wanted help from me? Ok, I did it differently, now I have android 5 + phone with root. There is one other problem, I can not change the default location of the phone: there is China, I want western Europe, because I can not use google play. I found a topic for honor 6+ https://forum.xda-developers.com/honor-6/general/honor-6-vendor-country-eu-t3498920 and that's probably the way it can be done. The question is where to get the eu.zip file for honor 6? Maybe someone has it and would explain to me the procedure step by step (if it is different)?
Hi Yellow_
QQ: how did you manage to downgrade to 5?
Explanation:
I've a H60-L12 with Android 6.0 and EMUI 4.0.1 and although everything [else] seems to work just fine, I can't seem to get Google Contacts to sync. The option slider in Contacts Settings is grayed out and unresponsive. Unfortunately, without my contacts this phone is all but useless. Hence, I've tried to go back to a previous version, but a simple restore [in TWRP] of my old backup fails after the upgrade. None of the instructions for rolling back were of any help, either.
I'd really appreciate if you could pass along your steps on how you downgraded your Honor 6 to Android 5. Thanks!

You can downgrade simply by HiSuite, see discussion (check also the earlier posts):
https://forum.xda-developers.com/showpost.php?p=80889343&postcount=3
That way you can go down to EMUI 8 but not earlier than to the firmwares with Security patch 07/2018 or later
And you cannot (and must not - people hardly bricked various Huawei phones, not just Mate 9) roll-back further because at that time Huawei changed the Bootloader
It actually means that you cannot go back to be 'able' to use old/good DC Unlocker - instead of DC Unlocker you will have bricked device that can only be repaired by Testpoints method
Also, only by Testpoints method you can rollback to Oreo, Security patch 06/2018 or earlier, that you can then unlock by DC Unlocker.
It was discussed in one of the threads here for Mate 9, about two months ago - please search
It was also asked and answered in another Mate 9 thread (during the last month or so - please search, you will find) about the available options to unlock Bootloader - but all goes down to the Testpoints, and some costs (to Halabtech, HCU or a particular Telegram group) that are about 30 Euros or more
Only those who never upgraded over Oreo firmwares with Security patch 06/2018 (that is, who still have the older Bootloader) can simply unlock the Bootloader with DC Unlocker for about 4 Euros ;-(

Hello mate.
I had tried before posting, but it didn't work.
So far the temporary solution I found (which I also tried for Dload and Hi suite, and it did not work, maybe I am wrong) is to perform a Downgrade from Emui 9.1 to 9.0, then you can perform a Downgrade to Emui 8.0. (but it is not possible to do it directly from 9.1 to 8.0)
I have an information puzzle, I still can't get to Emui 8, I keep reading, trying, buy 4 credits in DC, and surprise, they can't unlock it, and I already tried so hard, for so long that I'm seeing if I already sell Huawei, and I add it to my friends list "Never Buy again"
as ise with LG, Samsung, Xiaomi.
It is frustrating, he became a dictator huawei with his Sisteman "Emui" with which I can not even clean my quiet ass without bothering with his updates

Yes, exactly as in my post you cited. You downgraded from 9.1 to 9.0, then from 9.0 to 8.0, but you are still with the newer 8.0 sharing the same new Bootloader as 9.0 or 9.1 - the same new Bootloader that cannot be unlocked for 4 EUR.
You would have to downgrade further, to the older 8.0 firmwares (before GPU Turbo and/or earlier than Security Patch 06/2018 - they usually correspond to the jump from the old xloader to the new one).
But such downgrading is not possible by e.g. HiSuite, and if you enforce it by DLOAD, you would jump to the band wagon with several other users of various Huawei devices who similarly wanted to 'cheat' - but instead of unlocking Bootloaders for the cheap 4 EUR, they hard-bricked their phones.
There is only one method to downgrade to that old xloader.img - TestPoints: it requires to open the phone, to shorten pins on the TestPoints at motherboard and then to use a special loader and driver by Huawei to flash the board image. You may have problems to restore IMEI(s).
If you are interested about, search on XDA and outside, you will find the guides.
Actually, there were even instructions here (not very detailed - requiring further research for resources), under the Mate 9, Q/A or Guides section (e.g., I remember that I have asked for how-to at late Aug or early Sep, got a short answer but I never pursued to try it on my own)
E.g., attached is a photo of TestPoints pins for Mate 9
finally, I have the solution

Men, thanks for the answer, and sharing your time.
Well,
Finally, I found the solution that I wanted to apply a long time ago.
Which one?
simple; Take the cell phone, sell it and send the **** to Huawei.
