[Android Q&A, Help & Troubleshooting] kinaszek:
Hi Teddy

Thanks for your time spent on trying to help me here ! It's really appreciated!

I would like to say that -> 1 . yes exactly I seen that image when everything worked properly and it seemed that my phone will have system reinstalled , this animation was loading for about 1 hour or so, and at this point I have cancelled it and my screen went dark forever!

2. No it's just dark totally dark nothing can be seen, everything was just perfect before ( phone is from Germany used about 3 years I guess as the battery has such date on it 2015.03... ) I live in Poland so it would be the best if the software was in polish language.

3. Yes I hear the TalkBack for sure and it's no problem to enable/disable it , anyways screen won't come back to become working properly

I believe I might have screwed this phone a little or maybe I am wrong and I didn't do anything bad at all why I am saying this : short story how it was

1. I received it few days back and I was there with my sister I took it from her and was enjoying it like a kid enjoys a new toy :)

2. I was having fun on it, it happened it was dead because battery went down to 0% but I charged and everything was perfect, after that I started downloading extra stuff -> android apps and I noticed after another charging it stuck on Samsung booting screen ( White letters on black background ) it didn't want to move forward to the system ( normal functioning ) - at this point I knew it won't probably load anymore and I won't be able to use it so we went to console let's call it ->

3. When we were in the console there were few options, to reboot, to remove something / swipe ( I am not perfect in english all right so I did it intuitionally ) , I believe I for sure chose to remove /swap system and then as you mentioned in YouTubue 4 sec video I could see the samsung loading screen with that beautiful logo and animation, so I thought the system is reinstalling and it will take a while, and here I waited about 40 mins - 1 hour and I gave up and restarted the phone here, after that the screen went totally dark and dead but... ->

5. But after rebooting I was still able to see just 1 option, not any other , this one option was to connect device via odin and install system , with android alien green funny picture on it , waiting for connection

6. Short after something happened and I couldn't see even that, screen was dark and remained dark for good

7. Yesterday phone was taken by my friend to his home and he claims he reinstalled system, it was possible to move intuitionally by fingers and voice navigation but screen never came back

8. Now it's impossible to see anything on the screen in fact, I can't even determine if I am accessing pre-boot menu where I could reinstall anything or not, really I can't know it so it's just dark , standard buttons on the bottom of the Galaxy S5 are bit highlighted by white light like an icon on the left and right of the bottom wide button

9. The diode on the top left of the phone happens to light regulary in blue / dark colour

10. That's really all - I don't know here whether I should go to some dude working on phones and if he tells me $50 to fix it in Poland it will be bit over 1/3 value of new phone so is this worth an effort I don't really know, nothing helps really I tried everything my colleague used to fix some iphones himself so he isn't totally newbie to this subject
