PRS505 firmware image file checksum?
1526833661 6258688 cramfs.Fsk.img 81e782cea278b91fdbda1bf4391f71ea052079b2d983c8ffd5 a3c52f5bad6daf40227b3748826715ed12435f00df8ca389aa 5a860ad1004791690c7cdf9f226019575a5e8155847e4a8729 4c33f5056282d1e16fa66234cec28ebfaa6fc6bf2e982a81ad 4f3217220ee69dd66496674a0ac879078026d937cd8ed97756 84d5c5
What mean 1526833661? And how to get the checksum value? It's not MD5 or SHA1! |

First value uses unix cksum() algo and was only used on the very first PRS-500 firmware. Subsequent firmwares use RSA signature which is the last long hex string.

You need to generate the RSA signature with the private key. I doubt Sony will share it :P
