Hi. I too had a error while updating my LG GCC-4521B drive and have finally got it working thanks to this forum.
I tried out with je3.exe as asked to do by nekakav (Thank you very much!). Herez wot i did
- I searched for the file "je3.exe" in google and found this link in some page which i cudnt understand (was not in english). Herez the link.
I copied the file into "C: emp"
- I downloaded the firmware update from the LG site. Herez how i got to the link
http://us.lgservice.com/ --> Product Support --> Device Driver --> Combo Drive --> I selected Windows Xp version GCC-4521B firmware
Though the file has a .exe extenstion its a SFX Zip archive. I unzipped using WinRar (WinZip will also do) by right clicking and selecting "extract to here"
I got 2 files. One a readme file n other a ".exe" file. I cud even extract this ".exe" file using winrar. Therez the hidden ".hex" file which you asked for (ide.hex).
I copied all the files into "C: emp"
- I booted using a DOS diskette without CD-ROM support and changed the prompt to "C: emp". Here i typrd "je3 /?" to find out wot all options i had. Heres wot i got
usage 1 : JE3 [FILE_NAME.HEX]
usage 2 : JE3 [FILE_NAME.HEX] [PORT_NUMBER] /m
[FILE_NAME.HEX] : ***.HEX
1 - Primary Master
2 - Primary Slave
3 - Secondary Master
4 - Secondary Slave
/m is Boot mode Option
I have my drive connected as secondary slave. So I used je3 like this
je3 ide.hex 4 /m
And after a minutes, to my joy the LED of the drive started twinkling to life!
Think you should use /m if u have booted with a DOS diskette like me.
Hope this post will be of some help to you. Cheers. Bye.
