There is no such thing as damage at 0x410000 address for 8850, coz it's flash address is 0x200000 to 0x400000 equals to a 2mb full flash (MCU+PPM+EEPROM+PMM), there is no flash address beyond 0x400000 for 8850, or unless you are reading the flash address above the flash read limit or you are flashing a full flash for an 8855 which is 3.5 mb and is not compatible with an 8850 2mb flash ram

There is no such address as 0x410000!
Let me advice you something, you must not drop that phone again, coz it already has a defected FLASH RAM IC, one drop or another swim, you'll gonna replace/reheat that FLASH RAM IC!
