Hi.
Something is unclear for me in new firmware :
Here is what i've done :
1 put the jumper
2 flash bootloader (Ok, I see the progress bar going on, and the prog tells me it's succesfull)
3 remove jumper
4 launch hyper terminal, right com port, 115000Bauds
5 wait the writings as on your screenshots.
6 hold C Key + disconnect icon.
7 Push 1 key
8 send file Ymodem (new 1.0.0.2 firmware) OK, i see the progress bar, and when finished, some chinese writings in hyper terminal.
Disconnect.

I'm happy and burnt new firmware....
I Reset printer
I verify the versionof my firmware into the control menu from my printer, and it is still 1.0.0.1...

This seemed to go wrong.

What did i miss ???????

Help.

Hi William.

I'll try again with this link.

Please, tell me.
Every time i want to flash, must i begin with bootloader and jumper then hyperterminal ?
OR
Can i consider that i 've flashed boot loader once for all, and only use hyperterminal for next upgrades (no more flash boot loader and use jumper) ?

Thank you

Ok.
I burnt that fike, and it worked and showed me the 1.0.0.2 version number, in hyperterminal, and in printer screen .

No need to burn again bootloader.
Just hyperterminal.

You're right,no need to burn the bootloader again.
