Hello community, I need your help.
I have a Samsung S3 GT-I9300 (not rooted) and the problems began with a sometimes flickering display at approximately ~60% accumulator loading state.
The phone went off. After that the S3 could be switched on and worked ok.
Over 2 months the intervals for that behaviour became shorter and were more frequent.
Then on one day a message appeared such as that a new OS will be installed although NO new OS was downloaded! :confused:
I misinterpreted the situ, carried out NO backup and the following was that the S3 is now stuck on the samsung logo.
After removing the accumulator this ended and after reinserting the samsung logo appeared again.
The next behaviour was I connected the S3 via USB cable to load the accumulator then suddenly the accumulator symbol stayed gray and freezed. :confused:
I tried to reconnect, nothing changed. (I loaded the accumulator with the S3 of my friend and it worked)
Also now I cannot connect via USB with a PC, which worked always before the "crash".
Then I tried to enter the recovery mode.
The displayed message was:

Obviously the S3 is no more bootable. Probably caused by a hardware defect...
My next idea was to install a file manager to save the datafiles (contacts, whatsapp chats, viber chats, telegram chats, etc.)
I found an information about the AROMA-Filemanager (e.g. aromafm-1.91.zip) which is stated to work by booting from the external SD-card.
The displayed message was then:

So now I'm really helpless, what to do to get access to the datafiles...
The outlined facts:
1. there ist no working booting system on the S3
2. the usb port is not working
3. AROMA-Filemanager on SD card does not work
The essential question for me is compared to PC's: is it possible to get successfully access to the system such as 'knoppix software' for pc partitions?
What is the meaning of -- Appling Multi-CSC... ??
Is there a chance to flash e. g. an OI File Manager?? :confused::confused:
