Yesterday I did a One-on-One YouTube Update. I also Learned this about a 737 Firmware on Xbox 360 Jasper/Tonkaset.
1. JTAG Exploit Compatibility (7371 Kernel)
The 7371 dashboard/kernel is the last version that supports the original JTAG exploit. After 7371, Microsoft patched the system to close the vulnerability that allowed unsigned code execution.
⚠️ Once updated beyond 7371, JTAG is no longer possible. That's why 7371 is a golden firmware version for people looking to JTAG their Jasper units.
