Can you boot to diags? Or, did you erase that too?
If you erased EVERYTHING (why?) you either need to flash the partitions over the serial port, or wait until SOMEBODY creates a custom MfgTool profile that can flash these partitions.
There is a post in this forum by rastik about how he recovered from a total erasure of mmc, by flashing mmc using the serial port and a flash image sent to the kindle using ymodem serial protocol.
There is no need to erase the mmc (ever), and it just makes recovery more difficult. Yifanlu warned against doing any fastboot commands that you do not understand, and now you must learn new stuff to overcome the consequences of your actions.
You must either invest the time to learn how to debrick this using methods described in various posts (or read the freescale documents and create a custom MfgTool profile to flash the partitions), or you must buy a replacement kindle. It is up to you to decide how to invest your time and money resources. If you do not want to spend the time, then spend the money on a replacement kindle (and donate this one to somebody who DOES want to spend the time on it).
thank you all.you guys are very kind.
