editing 3100 flashes with hex edititors

[RavesRus]

ok i have done this before but hasve screwed up a step somewhere. What im trying to do is change my box keys and ird #. I have done this by extracting sa3 of u23 and modding it iin a hex editor, then reprogramming. (please dont recommend eraseing both flashes and reflashing and then using flash edit because that is not what im trying to do here)

anyways.....so I flashe sa3 of u23 with the modded flash with new keys and ird#
I think i was supposed to flash sa3 of u22 next then restream, but i forgot to before i took jtag off. now when i try to erase sa3, I keep getting error
"LSI control unavailable, using slow programming"
ird and box keys are all blank and im kinda stuck cause it been awhile

(will not power up at this time)

You need to get the first 60K written to flash 2, even with slow programming it should do that, in rare cases I have used wall 2 to get that done, but normally jkeys will do it.

ok i have re flashe u23 up to 60000 bytes.................now what
the power still wont come on and im getting the same jtag errors

[skinerd]

Sure you wrote a good flash to it?? Power won't come on, but jtag should pick up the receiver number and restore full erase/write function.

i have flashed u23 twice with 2 different flashes with same build config past 60000 bytes and i still cant read any ird # or box keys...........Iflashed sa3 of u22 aswell. Could that effect not reading the box keys......( i thought that information was only on u23)
Is my next option to try wAll2.2(which i have looked everywhere for, including in the public downloads........I must be blind)

[skinerd]

Have you tried a full write of U23? I know it may take a while, but worth a try?

Really the receiver number is located at offset FFF0h, 65520 bytes, so try writing 66000??

Shit, been so long since I had trouble with a -010, maybe it is the first 60000h bytes you supposed to write, or 393216 real bytes.........

[RavesRus]

yeah i tried that and still no luck

no luck with wall either.........this top j31 jtag aint helpin either, which is the real problem. It is impossible to write a whole fllash aswell with the slow programming.
Does any 1 have the layout for the bottom of the ird to cut the perfect slot for the quad jtag?
