Retail mode in CLT-L29 - Huawei P20 Pro Questions & Answers

After reading the information on the Retail Mode of the P20 pro, I can conclude that right now there is no solution to deactivate that mode, since the manuals that I have seen usually have the boot unlocked, I have seen tools like DC-unlocker which makes some versions of 20 pro, but this model CLT-L29 with a ROM demo is impossible at the moment, I'm right?

p20 pro Demo Reail problem

Hello,
i've read a lot of topic about my question.
I have a huawei p20 pro CLT-L29 version who was used a exposition model.
The phone works 100% but when i lock screen the retail mode starts.
I have tried to disble it from developer settings and tried a lot of time to make hard reset but demo mode still there.
I cannot ask to huawei the unlock code for bootloader because i dont want to send him the IMEI code of the exposition phone. I would like to use the online link to ask code but it doesnt work. The only way is calling huawei costumer service or sending an email but i dont lke that way.
There is another way to remove demo apk or install a firmware stock without unlocking bootloader? I mean some kind of apk that allow me to remove demo partition or demo apk from the storage.
Thank u
Why you being so shady about it? If it's legit, and not stolen, just send them the IMEI.
i got it from a friends and he said to not ask huawei the code..other ways?

Failed to switch 4G/3G slot on P30 Pro

From the first time I ever use my phone, like 1-2 month ago, this feature (switch default mobile data) never got right. i think some update will solve it, but after several month my this popup "Failed to switch 4G/3G slot" always appear, I use my dual sim for different purpose of network.
at first installing my p30 pro, i restore my phone from xiaomi mi mix 2s direct from google, i ever think to factory reset and brandly new fresh p30 pro, but to restore it will consume so much setting and have to move several custom data in my phone.
i tried to search anywhere in google even this forum, no one thread that discuss this problem, is there any way to troubleshoot where or what to do? i just tried to restart and to swith my phone slot 1 to 2 and reverse, but none of them work, MY EMUI version 9.1.0, Build version 9.1.0.168 (CE301E14R2P2) that sold over lazada.id flash sale Indonesian market.

Search about "demo" in Settings (it should be in Developer options) and uncheck that option.
That one is off, and still active.
I have the same problem. What is the solution
