First of all sorry about my english. I'm using a I7500 Froyo 2.2.1 ad I can't copy files in to my sdcard internal ad external. I have to do that because there are not gapps in the room, so i want to install the gapps signed of Drakaz but there is no way I can do that. I'v tried everything... copy paste by windows or cmd, push or pull by adb, transmit the files by NPS, nothing (by the way in the NPS there is not shown the phone icon only the sd cards). It allways show me an error window (device error I/O). What the ... ! One more thing, when I uncheck usbdebug and try to put something in the sdcards they unmount automaticalley. Please can anyone help me... please...!?
