Ranomez,
updated RkwinTools to version 1.3.5, now fully supports firmware with index "302A". Collected firmware now loaded to the device using RKBatchTool v1.8.
When remapping the memory, you need a PC to flashing the device via USB port!
For relabeling include devices used modified file 'parameter'. For a more detailed analysis, you should download 2 version firmware, disassemble and compare them to identify the differences in the files. Then you will understand - as I did.
