I ask for help because, I don't really know what to do
3 weeks ago I decided to try the JTAG Hack using an old infectus that I already used a year ago to do the Timing attack.
I solder the modchip on a brand new Jasper 512 and finally dump my nand (6xxx) then I update to 7371 and I dump again my nand 2 times
For the dump I use XavProg because the infectus software was reported not working with BB nand.
After that I extract rawkv and rawconfig from all the dumps -> 100% identical. I add rawkv and rawconfig in XBR-JasperBB-8955-3
Finaly I try to write the XBR with XavProg but it it was a failure (Erase Flash Erase .........) When I conpare the data writen and the original file, I found many errors
I never succed booting XBR or Xell at all.
After that, I decided to use a USB programmer compatible with nandpro.
I erase the nand and flash Xell .... And IT BOOT
I get my CPU Key, I succesfully open my dump with 360 Flash Tool 0,6, I check the "Date of manufature" and the "Serial Number" with the label on the case -> 100% identical (I also get my DVD Key but I have no data to compare with)
After that I try again the XBR procedure, but after writing the XBR rawkv and moving one badblock, I get a christmas tree
Xell tell me that there is a problem with my kv that's why it doesn't get the DVD Key.
I think that the dump made with the infectus is different from the one made with nandpro (different format or sometrhing like this)
If someone has an idea to help me with that, I don't know if it's possible to use a donor kv.bin decrypted, add my personnal info and encrypt it with my CPU Key.If someone can provide a Jasper 512 kv.bin with the CPU Key it will help me a lot
If one of the dev want my kv.bin to investigate, just send me a pm.
