1541U-II stopped responding after running Updater ver. 3.10 #31
Comments
Thats interesting - there is no 1541 Ultimate II (without plus) firmware 3.9, because it is too large to fit in flash. There is some 3.9 alpha version that fitted in flash, though. Recovery mode is a 1541 Ultimate II+ only feature. Depending what the bug caused to be overwritten, there might be a recovery by placing a "ultimate.bin" with the right content on the micro sd card... We'll investigate. |
Confirmed - that will kill the 1541 Ultimate II. Please do not try. I think I have seen in the source code what I need to know. Quite probable, placing "ultimate.bin" on micro sd card will help. |
u2-lite-recover-3.9-and-older.zip Instructions for recovery: 1st) Copy the attached "ultimate.bin" on a Micro SD Card. |
Thanks. Yes, the 3.9 was alpha.
That worked for me. |
Hi, I have a 1541U-II (not +) with fw 3.9. I downloaded and triggered a new fw 3.10 update (file update_3.10_au.u2u). It went good, but after a question "About to flash? Yes/No" (before the flash process) I accidentally answered "No". The C64 then asked to turn off. I turned it off and on again and since that the 1541U-II doesn't respond on the middle button. The only reset button works. I tried to find any solution on the Internet but I wasn't lucky. The recovery mode (holding middle button then turning the C64 on) doesn't work (asi I suppose it's the 1541U-II+ feature only). It seems that the Updater software has a bug that shows on a specific hardware. Is there any workaround how to solve this problem? Thanks :)
