Bricked R1 after update...no connection to PC!!!!

[usagi]

Hello! I try to explain my problem, sorry for my english.

My R1 was bricked, so I made everything like it was written in tutorial of lebellium. It worked very well and I was very glad about it. I made the update to modded firmware 4.0, but I forgot to put the DRK folder to the R1.

The problem occured when I transfered some music files and the DB refreshed. I couldnt connect the R1 to PC anymore. R1 was not appearing/ was unvisble. It was the same problem like before. I tried everything and on different computers, but still I can´t connect it to PC.

1) If I try to connect in Safe Mode, three PCs dont see the R1 and nothing appears in "My Computer". Another two PCs report about an "Unknown device". There are no drivers, so it cant be installed

2) If I try to unbrick it like the first time, before modding, nothing happens at all. I connect R1 to PC and make all steps like in tutorial (Hold power button and press once reset), the screen remains off like it should be for recovery, but the R1 stays this way the whole time. Nothing changes, no connection sound to PC, it remains off the whole time.


Please, help me!!! I really don´t know what to do.
