dump_rootkey

alternative for the 'acquire PCK1' step, without need for OtherOS/Linux.

• dump_rootkey

(needs 3.41, the 341-downgrader.pup works fine).

gameos method

eEID_RKDumper

alternative for the 'acquire PCK1' step, without need for OtherOS/Linux.

• eEID_RKDumper

(works fine on 3.55, e.g. 3.55-RogeroV3.4 works fine).

Howto:

• install package and run it
• It will then black screen (no GUI) and restart the console automatically
• FTP (other otherwise) retrieve your eid_root_key / PCK1 from /dev_hdd0/tmp/eid_root_key

Guide(s)

In short: changing Target ID of console inside decrypted eEID0

Semi Guide / Shortlist

• dump metldr -> Dumping Metldr
• acquire PCK1 -> EID root key
• dump flash -> Dev_Tools#Memdump Memdump 0.1 or (NOR only) on linux : dd if=/dev/ps3nflasha of=nor.bin
• Check flashdump -> Validating flash dumps
• extract EID0 section -> eidsplitter, manual extract or on linux : ps3dm_iim /dev/ps3dmproxy get_data 0x0 > EID0.bin
• decrypt EID0 using proper LibeEID (or any other proper eEID crypto tool)
• edit Target ID
• encrypt/rehash EID0 using proper LibeEID (or any other proper eEID crypto tool)
• paste inside flash dump -> [HxD] or any Hexeditor / binairy copy method
• If needed, because console is now on 3.56+, don't forget to patch CoreOS and Revoke too -> Downgrading patches
• write back to flash -> Hardware flashing or on linux : dd if=nor.bin of=/dev/ps3nflasha bs=1024
• PSgrade/JIG toggle -> [files/PSGrade]
• service mode reinstall Firmware belonging to that Target ID -> Downgrading with PSgrade Dongle
• remarry BDdrive -> [files/lv2diag/remarry]
• QA-toggle + combo button -> QA Flagging
• leave service mode -> [lv2diag.self FILE2]
• either enjoy XMB or a new brick
• Method to Avoid Bricks -> [[1]]
