Thanks both of you in regards of the suggestions. Would be awesome if the change boot slot from Fastboot would work. I guess it could not hurt, hopefully, to try it out first.
I think I was running the Stable Light version, 3.1 - Hopefully... I can restore things, at least there is a chance - and don't want to ruin it. So I have waited for some response, and 2 suggestions at least that might work.
-edit-
Okay... kinda.... worried.... It is in the loading screen, but it takes a long time.... it has not made an error yet, yet...... hopefully it is not doing something I don't want like ruining my data. It booted.... And now loading up again it shows the error again. :/ I'll try again, and then flip back to A... Sadly it did not do the trick for me it seems
Waiting again... Hmm, come on, come on.... Get in the system, come on! You can do it.... nope.... it restarted sadly, and sure going to come up with the message again. Yup there we go.... Suggesting a factory reset has to be the most stupid thing I have ever heard! Like really!!!
-edit-
Well, apparently it just flips back to A automatically, must be after the reboot and then entering the same nonsense thereafter of corruption. Well.... Hmmm, I will read up on the sideload and see if I dare try it out. I do wonder why TWRP would not be able to see the data, but I guess it is because it is not 100% functional yet maybe... I could try with my other mobile, just to see if it works there.
-edit-
Okay here goes hopefully something... So sideloading now - installing it at the moment. I hope it will do its thing without touching my data. I hope this will be a easy fix, I can only hope. At least I got my old mobile working yesterday as it was meant to, because of the other being broken for days. So if I can fix the new mobile it would be awesome. At least other options seems to be lost now. Although I would need to see if TWRP is actually able to do it on my LG V20 phone, to see if this would be a possibility for retrieving data. 82% is done, it is closing, will be wonderful if it works - would be amazing! Hope for the best.
Got a new "old" computer that could run windows 7, very nice as well... dusted it off and got it working - it is an old leet gaming computer, but it is nice that it is older as it can run Windows 7. Okay... the sideload is done.... the big moment I guess.... Hopefully.... Time will show... Starting up, so far so good. It seems to ave moved forward... ohhh there is my background moon!!! That's good.... Okay, this looks promising!!! OHHH YEA!!! I THINK I AM BACK IN BUSINESS, PRAISE JEHOVAH. Checking my note sheets.... Looks like it is all there... AWESOME!!! Perfect...
Have absolutely no idea why it would crash like that, it seems some of the others who have tried it on other mobiles on other forums that I have read, did not know either, just that the mobile became hot and then drowned... Seems to be a Android 10 issue overall.... Don't panic don't do anything stupid like resetting it all - just sideload the image!
Thanks for all the help guys - very nice... A stone lifted off my shoulder, or a bucket of stones lifted of my shoulder... I can rejoice and eat some chicken and go to bed afterwards.
Thanks again for the inputs, the mobile had been dead for near a week - so nice to be on the horse again riding!
Dearly regards
