| 13:17.25 | diJenerate | prpplague: this is the modem' datasheet: http://www.tranzistoare.ro/datasheets/208/464709_DS.pdf |
| 13:17.49 | diJenerate | prpplague: the firmware update is done via serial using AT commands... |
| 13:18.09 | prpplague | ahh interesting |
| 13:18.11 | diJenerate | prpplague: we have the utility to instruct for the NOR flash |
| 13:18.58 | prpplague | ahh interesting |
| 13:18.59 | diJenerate | prpplague: but the NOR is not written unless the bootloader either receives the firmware with a secpack file matching the one currently installed |

| 13:19.36 | prpplague | diJenerate: interesting |

| 13:31.13 | prpplague | thanks |
| 13:31.34 | diJenerate | prpplague: so I was saying... we can't find the secpack since the file that would have it... |
| 13:31.48 | diJenerate | prpplague: is nicely AES128 encrypted |
| 13:31.57 | diJenerate | prpplague: thanks apple :( |
| 13:32.12 | diJenerate | prpplague: plan b is to attack the bb itself |
| 13:32.38 | prpplague | yea, about the only thing you can do is a careful use of the jtag to dump values as they are being processed |
| 13:32.39 | diJenerate | prpplague: we discovered that the bb will allow writing to its NOR if it thinks the NOR is already empty |
| 13:33.33 | diJenerate | prpplague: well the encrypted file is the firmware image, the phone/itunes decrypt during upgrade |
| 13:34.37 | diJenerate | prpplague: the other approach is to figure out how to get the .arm based modem to think it's ROM is empty |
| 13:34.51 | diJenerate | prpplague: then it will allow us to write to it |
| 13:36.00 | diJenerate | prpplague: the other method is to dump the NOR and try to figure out how it identifies the secpack |
| 13:36.09 | diJenerate | prpplague: then we can fake it |
| 13:36.29 | prpplague | diJenerate: yea, sounds like you guys have your work cut out for ya |
| 13:37.23 | diJenerate | prpplague: pretty much |
| 13:38.00 | diJenerate | prpplague: some of the guys are working on getting itunes to spill the decrypted file to a mountable fs |

| 18:57.26 | MothaWork | bingo |
| 18:57.44 | MothaWork | i.e. I give them a non-populated PCB and a box of parts, and I get back boards with parts soldered down |

| 18:59.26 | prpplague | MonMotha: yea, all of ours are local to the DFW area |
| 18:59.46 | prpplague | MonMotha: as i understand it, most major cities have small assembly houses |
| 19:08.07 | MothaWork | yeah, I need to find one around here |
| 19:08.15 | MothaWork | I'm sure either Fort Wayne or Indianapolis has one |
| 19:09.55 | prpplague | MothaWork: yea, the main things you want to look for |
| 19:10.32 | prpplague | MothaWork: that they can take pick-n-place x/y data, that they have a good xray service, and that they have flying-probe tests available |
| 19:10.40 | MothaWork | yeah |
| 19:12.11 | MothaWork | we have a place for production orders, but not protos |
| 19:13.14 | prpplague | ahh |
| 19:13.32 | prpplague | we have a local company thats available for small run protos |
| 19:13.36 | prpplague | i.e. 10 to 20 |
| 19:13.39 | MothaWork | places that can handle finer pitch BGAs are hard to find in the midwest |
| 19:13.46 | MothaWork | we only need two of these |

| 19:14.59 | prpplague | i usually like to get atleast 3 |
| 19:15.35 | MothaWork | the parts on this are expensive enough that we want to make sure it works before building very many at all |
| 19:15.56 | MothaWork | in proto quantity the BOM for this tops a few hundred |
| 19:17.47 | prpplague | yea that can put a pinch on things |
| 19:18.46 | MothaWork | yeah, no $1000 FPGAs, at least |
| 19:19.44 | prpplague | hehe |
| 19:22.37 | MothaWork | the boards alone were a couple hundred each |
