Now, the devices shows a screen saying
"Firmware upgrade encountered
an issue. Please select
recovery mode in Kies & trie again"
Removing the battery does not change the situation.
I did not actually flash any firmware, so I would hope that the original firmware is stil intact and that there is just some stupid switch that needs to be triggered.
Can anyone advise what to do?
I also connected the device to a windows laptop with Kies on it, but to no avail... Windows detects it, but Kies ignores it.
