Don't extract the EZ5SYS.BIN in the 1.68 package to your MicroSD root folder unless you already meet the condition 1 and 2
1. Your EZ5 cart must already updated to boot from EZ5SYS.bin. If you have used the EZ5SYS.bin renamed into EZ5UPLDR.bin to update, then you must reflash with the smaller EZ5UPLDR.bin in the 1.68 package (copy only EZ5UPLDR.bin on microSD's root and update like usual. Hold R and touch ez5 logo on DS menu and press again R). the bootstrap loader update will not start unless the cart use the EZ5SYS.bin boot method.
2. Charge your DS power to full, connected with a charger will be better.
3. After you meet the above two conditions, extract the EZ5SYS.bin to your MicroSD root folder, put MicroSD into EZ5, EZ5 into DS, power up EZ5 as usual, the upgrade process will automatic start check the bootstrap loader version and upgrade. the process cost 3-5 seconds, Don't power off warning will displayed on the screen. power off DS while upgrade in the processing will cause your EZ5 cart bricked permanently. EZ5 will boot in desktop after upgrade. you can safe power off your DS now.
4. to verify the bootstrap loader version. just check the EZ5 boot menu by boot up EZ5 while R key pressed. Black BG and big white font means older version, deepblue BG and small white font means new version.
5. Upgrade process only show one time, once you upgraded sucessful, it never show up again. please use 1.68 kernel as usual. even rename it and flash it to chip will be ok.
donc si j'ai bien compris, vu que je suis en 1.36, il faut que je me procure la 1.68 et que je fasse la maj uniquement avec le dossier shell et le ez5upldr.bin ? C'est donc une maj obligatoire pour passer au firmware le plus récent, qui est le 2.0RC10. Ensuite je pourrais directement faire une maj avec le ez5sys.bin . Mais cela ne pose-t-il pas de pb de fiabilité si je saute plusieurs maj ? faut-t-il que je fasse des maj pas-à-pas ou je peux en sauter directement ?
Ai-je bien tout compris ?
