Save your old working tsop, then open it in Flashedit.
Record on paper all the "Build Data" info (it's under Build Config)
Now open N2 Tsop in Flashedit, change the Build Config to match your ird(4 letters) Also change all the Build Data info with data you recorded from your old Tsop, they have to match. That's the trick!
Now open Hexedit and edit EEprom to match your ird(change 4 letters)
Write both files to your ird using Jkeys
Program atmega with new file, just follow read me instructions
Stick the card in ird, wait 3 minutes,connect sat feed, watch tv!!
Worked on 3 diffrent receivers so far,2800 and 301.10

This works great on a 3700 as well. Thanks for the help.:beer:

Could somebody confirm the following are the correct Boxkey & IRD # for the TSOP mod for the ATmega solution?

IRD # 02AB4761 (decimal 4477-9361-67)
Box key 52 54 2B D8 07 DC EC 6F

Also, a seach of the 3900 TSOP bin file found at this site show that at address 107AC8, where the RSA key mod goes for the ROM10 solution, there are 64 "00" bytes.

Can someone confirm this is correct, and if there is a mod required at another location in the bin?

I tried this it didn't work for me. and this what I tried also.

I have been trying every read me file I found for the last two days to get my 3700 with an Atmega128 to work put nothing did.

I changed the TSOP in the posted file to my IRD Build Config CBIA. I did the same with the Eeprom in HexEdit CBIA and I also tried the OPTIONAL reverse AIBC. All I got is searching for Sat. I have good signal on another IRD....

I versionised the Eeprom and tried that I got wrong card inserted ERROR, I tried not changing any thing, got No Sat Error.

Do I have to change the BOXKEYS and the IRD? I know I am using the right files for the IRD and the Atmega128. It is driving me crazy, any suggestions please. THANKS

You said {Also change all the Build Data info with data you recorded from your old Tsop, they have to match. That's the trick}
You mean the BOXKEYS and the IRD # ? Please help

No the bokeys and ird # in hex and numbers must match what is required for the fix boxkeys 52 54 2B D8 07 DC EC 6F 02AB4761 R 00 4477 9361-67 for atmega

TY forenplayer,,this is the first atmega i have ever programmed and i got it working right now thanks to your post.

castaway, I am happy for you. Could you please tell me what you did at this step of the instruction?

Hook up Jtag, and run JKeys. Hit 'Save Mem', and then save it to somewhere you know. Maybe call it TSOP backup.

Now, open up Flashedit, and click on the 3 little dots to the right of the 'File' box. Browse to the TSOP you just saved in the first step. Hit Open,
then Advanced. Now, grab a pen and paper. Write down everything you see under 'Build/Software Info, exactly as you see it. Including Build config,
boostrap, Model ID S/W version and all the Build Data. Exactly how you see it!!

Now open the N2 TSOP from the files. Do the same thing, 3 dots, open advanced. Now make sure the info you wrote down matches the info under
Build/Software Info. If it doesn't, edit it to match what you wrote down. After that is done, save it as N2TSOPmod. Close flashedit.

Open Hexworkshop 4.2. Click on file/open, and select the EEprom from the N2 files. On the right side of the box, there will be 4 letters, starting with a 'C'. Edit that to match your build config. Just type over
the existing letters. Now save it as N2EEPROMmod.

Open up JKEYS again, and go to flash programming. Follow the prompts about unplugging and plugging back in and hitting 'ok' within 3 seconds. I did a
full erase 3 times, but not sure if that is needed or not. Click on program, and follow prompts until you can select the file you saved called N2TSOPmod.
Write it. Do the same for EEPROM programming and write the N2EEPROMmod.

Disconnect from computer, and program ATmega as per the instructions included with the files. After that is done. Plug your IRD into the wall
with the ATmega inserted. Wait 5 minutes or so, before you plug in your satellite feed or anything else. Hook everything up after 5 minutes, and do
a check switch.

Go watch TV.

Also got this going on a 4900. Thanks again forenplayer.

I got it. THANK you guys, the original read me did not say anything about the BUILD DATA. THANKS again for all the help.

Good to hear. Now go watch TV.

I try all your instruction all above but am still getting a black screen with program guide but no audio or video on my 301-013 single tsop. Can someone assist me here?

Thank you Forenplayer, I spent about 3 hours tonight looking for the solution to my problem. I'm glad I found your post
THANKS

"That's the trick" !

great post worked on my 2700 and 3100 in minutes thanks
