So... I see there's a new firmware released for hitachi drives and I decide to go through the normal steps as I have done many times before and restore the drive to its original state using my trusty VIA card. The restore process went through its various steps and all completed successfully (or so I thought). I now have a drive that won't eject (with my Xeno connectivity board) and an xbox that sits there with a green flashing LED when the drive is connected. No problem I thought! (after spending many hours trying to get the drive to detect in windows/hotswap flashing etc etc etc) I got my heat gun out and removed the tsop, flashed it with my original firmware, resoldered the tsop, powered up the 360, this time no flashing green LED but an eventual E64 and 1 flashing red segment. After some fiddling I removed the tsop again, reflashed it with another known working backup of my drive, resoldered the tsop and exactly the same again. It's as if the drive is totally dead.
I'm trying to work out what technically went wrong and why a tsop flash also didn't work.... Any ideas?

Did you encrypt the TSOP firmware? When remoing the chip and programming it off of the board you need to generated a pre-encrypted firmware before flashing it.

Also heat gun can damage the PCB if your not carefull.

Thanks for the reply mate,

The PCB is still immaculate, I work through a x10 optical loop and the board still looks as it did before the chip was removed after cleaning. My firmware dump is from "Maximus-Garyopa_XTRM-HITACHI_v2_3_Stealth 8in1" (was.bin). I thought the raw dump was still encrypted? Is this my error? Do I need to encrypt the bin file before flashing with an external programmer?

Thanks,

Mark

Ok. I've done some reading after you mentioned encrypting the file, I now have an encrypted file (IMG:style_emoticons/default/smile.gif). Hopefully the drive will survive the tsop being removed for a 3rd time and I can try flashing when I get home from work.
Thanks for the heads up mate....

Any dump you do thru SATA is unencrypted. Any dump you do directly from the TSOP is encrypted.
Therefore if you have a SATA dumped original you must encrypt it with software like maximus toolbox before flashing with the external programmer.
I think your problem will be solved when you get home.

Brilliant, thanks for your help!

I've spent too long away from the xbox360 scene fixing/reworking PS2s, I'm now playing catch up! Thanks again mate.

This poor tsop is doing very well, I've removed, reflashed with encrypted firmware and resoldered for the 4th time and the drive is now fully operation once again.

Many thanks! (IMG:style_emoticons/default/smile.gif)
