Problem after edit platform.xml. No Internal Memory access, but some apps working.

[genius88]

I have problem like this. I've edited file /system/etc/permissions/platform.xml in stupid way. I'm tried to add a codeline that pre exists and I didn't saw that line, so I add <group gid="media_rw"/> in most pleasent place... on the end. After that and reboot I have no access to Internal memory, some apps like Titanium Backup don't have also, but most of it have. In file manager I can see how much of space left on it, but I can't see files, like a memory was cleared. I've tried to: swap edited file on oryginal (with permissions rw- r- r-); swap all folder permissions (with saved permissions on all files rw- r- r-); dirty flash ROM... and several other things that I've forgot at moment I'm writing this.
The most important thing. All content of moded file is below. And most most important thing, I'm trying to save my files in advance of flash.
Please help.

I've just discovered that format sdcard gave me full access from ES File Manager. Before I have access, but when I've formated ext. sdcard it suddenly shown up in main window with shortcuts. Maybe when I delete proper file which administrate files I will gain access to internal memory and device start to work normaly? Which file on internal memory could be responsible for files strukture, memory access? But not working internet still will be a problem... :|
