Yes

Right now thanks to Borja Viera I used the working OS to make a "sdfuse" folder on the internal memory, put the .qsb image file into the folder and flash the phone through diagnostic mode. I have got right now android 5.1.1 on it and it booted normaly :) However the connections still aren;t working. I managed to enable "OEM unlocking" then got to the fastboot mode with a bit of help from AIO tool (because turning the phone with pressed "Vol Up" and "Vol Down" buttons at the same time makes the menu but no "go to bootloader" shortcut over there). Unlocked the bootloader manualy with minimal ADB. Then I wasn't able to put TWRP as the recovery because of some weird error comming every time I tried the command. So I flashed the phone once again back to CM 12.1 soft only to get other "the better one - with many options" bootloader. Tried flashig TWRP once again and voila! TWRP working!! Bootloader unlocked! In a while I will be downloading some CustomROM and turn this phone back to life... I hope so ;)

[UPDATE]

Tried 5 different ROMs:

Two Cyanogen:

1'st - black screen blue led usb diagnostics state with port 9006 opened

2'nd - frozen on loading screen

Three CustomROMs:

1'st Official Lineage

2'nd Unofficial Lineage

3'rd AICP-12.1

All three are not booting. Phone resets itself on loading screen -> boot loop. Do you have any sugestion right now? In TWRP everything wiped and ROM installed on clean phone. Gapps installed too from Open Gapps website. Eveything done right with the instructions.

Is this phone really damaged?
[Zuk Z1 Q&A, Help & Troubleshooting] ankurpandeyvns:
If you're still in warranty, the best bet will be to get it replaced. Because it seems like a serious issue in the hardware.

Do you have any telegram account, we could make things faster if we communicate that way.
[Zuk Z1 Q&A, Help & Troubleshooting] kotex:
Asked my firend about it. The phone is like 1 month old. He was making some pictures and the phone suddenly died and got to boot loop. He bought it new on ebay. Shipped from China. He already made some research about the warranty before he gave it to me. He made some calls and emails to customer service here in Germany and they told him that he has to send the phone back to China. No warranty in Germany. It is not worth to send it back to China because of duty tax on the way to China. They send him this phone on some special shipping method to avoid this taxes and stay with profitable shipping price. But if you need to send it back they won;t help you at all. And the dispatch price is a no-go.

Since I have decent experience with electronics and flashing various smartphones he gave it to me with a though that I will be able to bring it back to life.

I already said when I started this topic that I suppose that this phone has some damage on the mainboard because of the weird behaviour. I just want to be sure about that and try everything I can before I tell him that he wasted his money by buying this phone.

I want to thank you for your support! If you have some ideas what could I still try I will gladly listen.

[T-Mobile Samsung Galaxy S8 Questions & Answers] pete4k:
I'm in peculiar situation: I bought my T-mo S8 direct from Samsung, paid in full, so now whom do I go to unlock my SIM? People from Canada received unlock code together with copy of bill, but I can't find anything on mine, any suggestions? Of course I want to do it as painless as possible and I want to ask here before calling customer service and waste few hours.
[T-Mobile Samsung Galaxy S8 Questions & Answers] quasidodo:
I'm in the same boat as you
[T-Mobile Samsung Galaxy S8 Questions & Answers] escabar:
I am in the same situation. From my understanding of past and present TMo devices, the account has to be in good standing (EIP/equipment paid off) AND your device needs to have 40 or 45 days (someone correct me) of continuous usage on TMo network before you can request the Device App unlock = carrier unlock.
[T-Mobile Samsung Galaxy S8 Questions & Answers] quasidodo:
So just wait until then
[T-Mobile Samsung Galaxy S8 Questions & Answers] pete4k:
As I suspected, I called Samsung to unlock my phone, they told me to call T-mo, called T-mo, they told me to call Samsung, wasted already 1 hour on this.
[T-Mobile Samsung Galaxy S8 Questions & Answers] nygregi:
It's 40 days, that is I was told by CS. After that you use "Device unlock" app on your phone and choose permanent unlock.

Same techniques for S6 and S7 and it worked for me.
[T-Mobile Samsung Galaxy S8 Questions & Answers] pete4k:
First of all I'm leaving on a trip in 20 days, second, the phone is paid in full now, not in 40, third I didn't buy it from T-mo so most likely they wont have any record of it. It's total BS and should be illegal, in Canada Samsung sends unlock code with the phone., but I guess here consumers have no protection. Last time I'm buying carrier phone. This whole locking of the phones is leftover from carrier subsidies and should not exist outside of those plans, if they still taking place. And a funny thing is I have no intention of leaving T-mo anyway and there are services to unlock phone for money. I remember some law about phone getting unlocked when paid I read about few years ago, but can't get any details now.
[T-Mobile Samsung Galaxy S8 Questions & Answers] nygregi:
That is T-Mobile branded phone, and that is their rules, sorry for that. What you can do, before going on the trip, on that app/ choose Temporary unlock, it's good for 30 days and you can have it up to 5 times in a year.
[T-Mobile Samsung Galaxy S8 Questions & Answers] mrbear01:
You can call T-Mobile and let them know that you are travelling out of the country on ___ date and ask for an unlock code for a long time customer. It has worked for me in the past if you get the right rep.
[T-Mobile Samsung Galaxy S8 Questions & Answers] abeben:
I have the same problem, I bought the phone from Samsung.com and there was no option to purchase an unlocked phone. I am traveling in two days for a few weeks and I called Tmobile several times trying to at least get a temporary unlock and even that cannot be done. They said it has to be on their network for 40 days. I even called Samsung and they said all the unlock codes are sent to Tmobile and only they can unlock it due to the stupid Device Unlock app. You cannot unlock it even if you have the code, only the app can unlock it. If I didn't like the S8 so much I would have switched to the iPhone 7. Absolutely ridiculous!!!
[T-Mobile Samsung Galaxy S8 Questions & Answers] pete4k:
I still don't understand how T-mo will know the phone you purchased direct from Samsung is paid for and should not have SIM locked to begin with.
[T-Mobile Samsung Galaxy S8 Questions & Answers] kindongo:
I have the same problem with my S8. Bough it directly from Samsung. I contacted Samsung and they told me that I need contact tmobile; contact tmobile and they told me that my phone does not show in their system as a tmobile phone because I did not buy it from them. I need my phone unlock so when I travel overseas I can use a local sime card. I don't want to wait until 40-45 days go able to unlock my phone and then not be able to return it to Samsung. There some unlock services charging $50.00 plus to unlock it. I don't want to expend more money, since this phone is already very expensive.
[T-Mobile Samsung Galaxy S8 Questions & Answers] pete4k:
It's not even about money, this should be illegal. This whole business of locking the SIM card is left over from contract subsidized phones and I could perfectly understand that phone belonged to phone company and you just leased it until end of contract. Now I praise T-mo for getting rid of this practice and changing whole industry, so now at least you know what are you paying for and how much. But now SIM locking shouldn't even happen anymore: if phone is stolen/unpaid for, blacklist IMEI and also you can unlock SIM for the fee, even if it is stolen, so what purpose this SIM locking serves? Canada gets unlock code with the phone.
[T-Mobile Samsung Galaxy S8 Questions & Answers] kindongo:
Anybody had any luck getting the phone unlock.?I waited too long to return the phone, now I'm stuck with it.

[T-Mobile Samsung Galaxy S8 Questions & Answers] fragg3d:
I was in the same boat as you. Went through T-Force on Twitter and seemed to have gotten a rep on the first go who understood the situation and submitted my IMEI number to the right place. Your IMEI number needs to be added to their "device distribution inventory system" and needs to be submitted to their highest level tech support, this allows the Device Unlock app think your phone came from T-mobile's inventory and will let the app unlock your phone.

There may be hope for everyone in the future, this one of the final responses I got from them:

"I am right there with you. It definitely makes things harder on both sides since the phone isn't technically bought from us, even though it is branded a T-Mobile phone and our system rejects any IMEI that didn't come from our inventory. None the less, we're all about giving you full access to what is yours. Teams are currently working on a process update that'll make things a lot more seamless, but in the meantime we've got this work around! I really appreciate you taking the time to reach out to us today!"

14 hours later I tried the Unlock Device app and requested the permanent unlock and was greeted with "Unlock Approved: Mobile Device is permanently unlocked"

Device is fully unlocked, tested with an AT&T SIM card and everything worked fine. After 2 reboots the Device Unlock app even disappeared from my phone. I'm so happy with how fast T-Mobile dealt with this. The more people that make a stink about this issue on social media hopefully T-Mobile will find a permanent fix for people buying a SIM locked at full price and have it easily unlocked under their standard procedure.

Did this work for you and were you able to successfully unlock ?
[T-Mobile Samsung Galaxy S8 Questions & Answers] INGHUGO:

Sim unlock services will unlock the device temporarily. T-Mobile can and will relock your device at random. The only true way to unlock the device is through their idiotic app.
[T-Mobile Samsung Galaxy S8 Questions & Answers] peta1381:
Hello, i´m in the same situation with my S8 bought directly from Samsung´s web in pre-order, fully paid, and with t-mobile as a carrier. Reading this post, i decided to contact the t-mobile guys via facebook, and they asked for my IMEI number and told me that they will contact Samsung and in 72hs i should trie the permanent unlocking procedure via the device unlock app preinstalled. So nearly 24hs has passed now, tried already and still getting the "unlock failed" message, so i guess i will wait for the 72hs requested by t-mobile and try again. Next monday i hope to bring some good news to you all. Crossing fingers here!!!

edit: forgot to mention that i already tried the doctor sim service, the are trying to unlock my phone for over a month now and still no succes. Also tried with unlockingcodesource.com, don´t ever try with them, i paid for their service and found myself sending more than 3 emails a day to get any transaction confirmation, some information of them even working in my unlocking service, and all i recieved were emails telling that soon they will contact me with the requested information. Got tired and asked paypal for a full refund. Finally i contacted unlockbase.com, and they told me they can unlock the S8 via the device unlock app from t-mobile, that they had already done that service... i paid for their service, and the next day recieved an email telling they couldn´t unlock my phone and sending my a full refund. Then i started to get really worried, and got lucky to find this post and contact the t-mobile team. As i already told, i´m still waiting for my device to get unlock, but it´s been only 24hs from the 72hs that t-mobile ask me to wait. So let´s wait and see.

Me too. It took almost a week but finally i´ve got my t-mobile fully paid galaxy s8 permanent unlocked. Contacted the T-Force as they are called via facebook messenger, and they contacted samsung and almost a week later i tried the permanent unlock ption in the device unlock app preinstalled, and got the "Unlock approved: mobile device is permanently unlocked" message.

Just for the record, i bought the s8 on pre-sale from samsung´s web page, fully paid for it, choose t-mobile as a carrier, and used it with a t-mobile prepaid plan for almost 10 days. Almost a month later, tired of waiting for doctor sim to unlock my device, read this post and contacted the t-mobile people over facebook. After unlocked i contacted doctor sim asking for a full refund, and got it the next day, so don´t hesitate, contact directly t-mobile, they will sure help you.

I'm trying the same thing via twitter t-force. It's a shame that Samsung made us jump through hoops like this. :(
[T-Mobile Samsung Galaxy S8 Questions & Answers] krazyq:
If you purchased your phone from T-Mobile and paid the phone off, you need to wait 40 days before you can unlock it.

If you purchased a Tmobile phone from Samsung

Contact tmobile via fb chat or twitter

tell them you purchased a tmobile samsung phone from samsung.com and that you need them to add your imei to the database.

They will ask a few verification questions then take your email and say it'll take about 3 business days

You will not get an email however just open the unlock app in about 3 days and press permanent unlock and it will work.

I was able to get this done successfully for 2 S8s and 1 S7 Edge all purchased from Samsung directly.

Good luck, hope this helps

They worked with Samsung to add the IMEI to t-mobile unlock database.
[T-Mobile Samsung Galaxy S8 Questions & Answers] mdiaz33685:
Correct, took about a week for me also to add the imei and then for the device unlock to work.
[T-Mobile Samsung Galaxy S8 Questions & Answers] jim262:
Probably already is unlocked. If you can take your sim and plug it into another phone and it works, it is probably unlocked. If you have the capability take another sim from another carrier and plug into your S8. If it works, it probably is unlocked. I ordered mine from Samsung also. I am on T-Mobile, but I also have access to Metro PCS. Now Metro is IMEI dependendent, but my phone works with either. If your device will work with one sim and one sim only then it is locked to that network, but if you can swap sim cards and attach to another network, it isn't your phone that is locked. Bottom line, the Metro sim won't work on any my other devices, but I can swap my T-Mobile sim in any device. From what I understand, in their quest to be the un network, they have done away with the practice of limiting sims to one device/IMEI numbers. I remember that used to be an issue when traveling abroad and I would need a sim from a foreign country.

Yes, I bought it on t-mobile, I contacted t-force on Twitter and told them that I was going to a another country , I show them my purchase receipt and a lot of patient but in 5 min they unlock it*
[T-Mobile Samsung Galaxy S8 Questions & Answers] fragg3d:
A SIM locked T-Mobile S8 will work on MetroPCS without having to do anything, though a locked MetroPCS S8 will not work on T-Mobile. We're not talking about the SIM card only working or locked on to one device, you are correct on that. However I guarantee if you try and stick an AT&T or any other carrier SIM card in your phone it will come up with this screen: http://i.imgur.com/9dmf7qQ.png if you have not used the "Device Unlock" to unlock the SIM slot for use overseas or with a different US carrier.

T-Mobile branded Galaxy devices sold direct from Samsung.com are in a unique situation as T-Mobile is the only carrier that does not use a standard unlock code, it can only be unlocked with their app. And since the phone did not come from T-Mobile's inventory that app will never work because it verifies the IMEI of the phone was sold by them, and it was not and there for is not in their system. You must contact T-Force (twitter seems to work the best) https://twitter.com/TMobileHelp explain you bought your phone from direct from Samsung.com and need your IMEI # added to their "device distribution inventory system" as explained in my and other's earlier posts in this thread: https://xdaforums.com/tmobile-galaxy-s8/help/how-to-unlock-sim-t3597186/post72443291#post72443291

---------- Post added at 12:58 AM ---------- Previous post was at 12:50 AM ----------

This is a different type of unlock request than the what the OP posted about. Any basic support rep can whitelist your devices IMEI # in the "Device Unlock" app as long as it was sold by T-Mobile, rather than one bought from Samsung.com. The whitelist request just bypasses the 40 days on network (and other unlock requirements) and just depends on the mood of the rep you talked to. If you talk to someone who won't override this, just keep trying till you get one that does.
[T-Mobile Samsung Galaxy S8 Questions & Answers] DarkerBob:
Similar situation. I'm Canadian and live in the USA for 6 months of the year. Bought the 2 for 1 deal on Samsung.com. Paid in full. Stuck with Tmo for over 40 days then went back to Canada.

Tmo gets a bit cranky about me roaming for months on end even though I have the North America plan. They send some really *****y texts and eventually threaten to shut off your service. I decided to grab a Canadian SIM and that's when I ran into troubles.

Customer service was less than helpful as you may have noticed if you ever call for anything other than the absolute basics. Eventually I drove back to the US (for the eclipse) and went into a Tmo store. The guy in store was great and got through to the top level tech guys who added the phone to the back end white list and said "wait 72 hours". By which time I was back in Canada and still locked.

Turns out you can only unlock when you are "on network" and not roaming. But I figured it out. I turned off cellular data and hooked up to WiFi. That did the trick - Permanent Unlock granted!
