So I did my first RGH and it was a Jasper 512MB with CB 6750 (so no problem). I had a few issues but what I thought I would post about is the weird-ness I saw with my capacitor between A and Gnd.
When I first tried glitching it I had a 68nF cap between A and Gnd, but the Coolrunner's green light never blinked it just had solid red. I re-soldered some connections and removed the cap and tried again. This time it would glitch but it took several minutes. One thing I noticed is if I touched the cap to A and Gnd the green light would stop blinking but the second I removed it, it would glitch properly. This made me think I should use a different cap value. I added some longer leads so I could clip on different cap values to A and Gnd (instead of soldering the caps directly). I started by putting the 68nF cap on the long leads and the first try had it glitch right away. But some times it took longer so I started experimenting with adding capacitance. For me I found what worked best was about 90nF with the 8 inch leads using 24 gauge wire.
I tried replacing the wire with a small resistor but that didn't work (the green light wouldn't blink). I ended up just leaving the 8 inches of wire coiled up in the case and it seems to work great. 8 out of 10 times in 20 seconds or less. Just thought I would share my experience because I didn't see any one else post this kind of behavior. Every case I've seen where the green light wouldn't blink, it was due to faulty soldering.
One other thing I noticed is when using rawflash V3 and flashing my modified kernel, I got a whole lot of "block XXXX seems bad status 0x00000240" I thought the write failed but when I booted the system it went right to the dashboard. Is this normal? Again I didn't see this posted any where.
