Dear Sir.
Sorry for the bother, but the only firmware I found was this to JM4 Looper.
I don´t know if it will fit for my Spider Jam Amp.
Afterall it cames in .bin extension, also very complicate to open.
Please, take a look and show me the way to make those upgrades:

WARNING: BACK UP YOUR FILES!
The v2.09 update will erase all the internal recordings you have made. If you want to save them, use an SD card to create backups (via the TRANSFER ALL TO CARDcommand) then copy them from your SD card onto your PC for safe keeping (using an SD card reader). You can then reload your files using an SD card at any time after you�ve completed the update.
