S5830i flashing problem

Yesterday I got a S5830i that I should try to fix. The background story is that the Google Play Services took over aprox. 100 MB (a large amount of device memory), so they were deleted or their updates were. That led the phone to being unresponsive so the battery was removed (that's what I was told). After that the phone keeps reseting ... splash screen, samsung boot animation ... over and over again.

So I checked what could be done. The phone has a stock ROM and it's not rooted. First i've found out that /data cannot be mounted (Error mounting data). Other topics suggested only flashing stock firmware using Odin.
Then I installed drivers on a windows machine, prepaired Odin with pit and a stock firmware. Then I've put the phone into download mode. The problem is ... the phone is not detected in Odin whatsoever ... changing drivers, installing kies ... nothing. Device manager says that the phone is unknow device and no driver helps.

The last attempt was on my linux machine running a ubuntu 14.04 derivate. Using heimdall 1.4.0 I only get Device detected. Using a hemdall frontend I can get it to print pit too ...

And here it stops. I'm always getting error that setting up interface has failed. Just for test I flashed the CWM and some ROM from xda. Everything was invalidated after restart ... stock recovery, error mounting data.

Is there anything I can do? I really tried almost everything.
