Hello, i'm trying to fix a 7" sylvania tablet that i have no info about for a relative of mine. Thing is, when android 2.1 starts, a popup (android.process.acore has stopped) comes up indefinitely and i cannot use the tablet. This might actually be a simple problem to fix, like clearing the contacts cache, but i cant open any apps. I tried to factory reset it, using the guide in this forum, but i get the message No recovery image is found, try recover from SD. I was trying to identify the tablet hardware for a manual update but was unsuccessful, since adb isn't working either, probably disabled. Since i have programming experience the last thing i thought was to create and install a debug apk via the sd card, but i can't access the sdcard because of the error described above. I'm out of ideas, can anybody help? Is it possible to id the hardware by opening the backcase? If so, are there only 4 screws, cause after removing them the backcase still is tightly locked. Is there a keybord shortcut that can trigger a android factory reset, safe mode, or at least show the about screen and see the hardware version.
