Hi,

I got a KT3 serial number begins G000K9.
Probably MMC was erased.
I could partly reflash it with diagkern.bin and mainkern.bin no more files was flahed (thanks for description). Now the partitions are missing and kernel freezes. Is there a description about partitions or utility how I should create them or the whole process (serial port connection is working, these recovery menus didn't help:
I. Initialize Partition Table (fdisk) and format FAT
O. Format and overwrite FAT partition)?
