Various embodiments of the present invention provide systems and methods for decoding data in a non-binary LDPC decoder with targeted symbol flipping. For example, a non-binary low density parity check data decoder is disclosed that comprises a variable node processor operable to update variable node symbol values according to a plurality of elements in a non-binary Galois Field, a check node processor connected to the variable node processor and operable to perform parity check calculations, and a controller operable to perform symbol flipping and to control decoding iterations in the variable node processor and the check node processor.
