Preface.
Last time released Samsung S5230 with firmwares S523MXXXXX(with Micron flash IC). Old firmwares don't know how to work with Micron, thus downgrade kills phones. Good old COM port boot-loader repair method does not works. There is only one way - repair it by RIFF box JTAG.
Procedure.
1. Repair boot-loader by RIFF box JTAG.

Important ! ! ! !
In case Your phone does not enter download mode after repair, You need to erase boot area in NAND.

Select Samsung S5230 in JTAG Manager,
Switch to DCC Read/Write TAB
Select ROM1 Address space
Uncheck ALL options
Enter 0x00000000 for Address
Enter 0x00020000 for Data Length
Press "Erase Flash"

Now reconnect phone and click "Resurrection" button again.
Phones with Chip ID: 0x002C/0x00BA will work ONLY with Year 2010 firmwares, JGx or JFx ! DO NOT flash the phone with old firmwares !

2. Flash newest
firmware S523MXEJF1 (or another Year 2010 firmware, JGx or JFx).

3. Enjoy!
