S20+ SM-G985F locked to Spain Movistar (XEC) - any way to unlock for Czech rep? - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi,
A short story about a cheated friend with a baby at the end. Im findig solutions for her.
Could anyone please advise if and possibly how to unlock S20+ SM-G985F locked to Spain Movistar (XEC)?
Just making calls with a Czech SIM is enough.
From what I've browsed the information the code to unlock the SIM may not work with this operator and it's not out of her sight.
After restarting the phone from CZ SIM o2 phone does not want the code to unlock operator lock.
If I understand correctly, changing the ROM will not help. And I can't possibly put in any but some matching CSC or CSC change.
I have tried SAMkey but according to the description it will not unlock this tel. Or does it?
The log from SAMkey is below:

Short story.
Friend of mine with a small child bought a second-hand mobile phone with money saved from her maternity leave and without consulting me. Unfortunately, the person in question was a scammer and sold her an S20+ locked to the Spanish operator Movistar (XEC), which I only found out later. He assured her that it would work for her in CZECH.
I'm trying to deal with the return, but I would like to find a solution for sure that she will be able to use it if we don't catch up with the scammer. I'll catch up anyway and turn it over to the police, but I need to help this friend's mom.
Thank you very much for your help and directions.

Huawei E5577Cs-321 Unlocked problems

Hey,
I have been using a Huawei E5577Cs-321 Viva which was unlocked when I got it. My software version is 21.329.01.00.00. Web UI version 17.100.11.08.397. I am having problems when using it, it seems certain sites trigger the router login page. When I enter for example yahoo.com without (https://www.) the router login page seems to open instead. It also happens when I use only www.(some websites).com. I figured it out that it has something to do with security, since when I use https://www.(some website).com it works. The funny thing is most sites seem to work ok, but this is a huge pain and also you can't always do this for weblinks or web redirects. Is there a solution? I've reset the router, used multiple browsers and different phones and laptops and it continues to happen.
I have the following text in DC unlocker
DC - Unlocker 2 Client 1.00.1277

Can I downgrade without the modem locking? If so which softwae should I try? Right now it is V4 unlocked but, I was hoping if I can change the software it might work.
Solved. Router was downgraded to v. 21.328.62.01.397 and new Web Ui was installed. The router login redirects aren't happening as much as before.
Nobody has found a solution for this yet?

Thanks brother, I was away for a while and did not see your post. I had successfully done the same with a T-mobile webui also around 6 months ago, it was a Russian or Eastern European, maybe Romanian T-mobile webui. This T-mobile webui stopped the redirects but it blocked a lot of sites, some social media, torrents and even regular sites, so I removed it. I then installed a generic webui and it was working fine until a few weeks ago and it started acting up again. Due to covid there hasn't been much work, so I haven't been buying data and using the 4g at all. Is your webui the same T-mobile one or a different one? Also does your device work in 3G? My device will only work on 4G or LTE. On 3G it will connect but will not load any pages, very low KB transfer rate less than 50KB/sec. I've tried different sims but it won't work in 3G. Can you send me the version # of your dashboard and firmware so I can confirm or not?

Sorry late reply, try this. Read whole thing carefully before trying. See if you can calculate the nck code without wiping your NVram. Meaning use only the usbsafe loader or the oem-nck_e5573b.bin loader.

The unlocking is performed with a special unlocking file which you'll need to upload to the modem/router. To request the file, you'll need to get the response of the following commands:

To get the response for AT^DIESN command, you'll have to run custom firmware, which you can find somewhere on the internet or make yourself with https://github.com/Huawei-LTE-routers-mods/huawei_balong_modfw_kitchen.
Send the output of AT commands above to [email protected] email and wait for 4-10 days.

You need to be technologically competent to install the file by following the readme and figuring out everything by yourself.

Hi. Is it possible somehow to enable SSH for E5576 (or any other similar router). When i try to login then message says "Connection refused". That means the SSH service is enabled on the router.
