Talk:Flash:Encrypted Individual Data - eEID

Objsuites Experiments

• A series of experiments was conducted back when objsuites had not yet been leaked
• These experiments involved changing the serial of the device, filling the request, and receiving the response back in a txt file called request_idps.txt
• The following was observed:

Changing the serial (except for the first 2 chars) changes the following regions of the eEID:
eEID0 (all of it, except for the header parts)
eEID1 (does not get flashed)
eEID2 (no changes on pblock, likely no changes on sblock, since it does not get flashed)
eEID3 (does not get flashed)
eEID4 (nothing gets changed)
eEID5 (last 6 digits of the idps and 0x750 bytes) (the first 0x2B0 bytes remain the same) (in the case of producing a retail eEID the first 0x280 bytes remain the same and 0x780 bytes change)

Changing the serial (and the ecid) changes the following regions of the eEID:
eEID0 (all of it, except for the header parts)
eEID1 (does not get flashed)
eEID2 (all of pblock)
eEID3 (does not get flashed)
eEID4 (all of it)
eEID5 (all of it, except for the header parts) (the header also changes from 0730 to 07E0)
