How did you get past being stuck on the teamwin screen?
I have the same problem as you had. How did you manage to get back to the format option screen? I am totally stuck.
Hi, I am sorry but I totally forgot how I got through that 
Maybe I tried to restart the phone
Hi, ok, thanks anyway.
I then got stuck totally after trying to reformat, as you did - “I rechange format system of the data partition to Ext3 then to Ext4 and it seems to have been useful”.
My phone is now dead.
As @SuzieQ have said, your phone is probably not dead and could be restored with traditionals tools and rigourous step by step process
