from what I know: you do not have to mod the eboot.bin or param.sfo in the GAME DISC folder since they are not used. which files are important for the boot process are the ones in the update created pkg folder (dev_hdd0/game/). so it should not matter what you patch in your game folder i.e. dev_hdd0/gameZ ************* [ - Post Merged - ] ************* Hi @ all, here are all the tools I used for resigning and editing eboot.bin and param.sfo in the dev_hdd0/GAME/ folder, which is created as a result of an update.pkg. other eboot.bins or param.sfos are not relevant for fixing updates. https://www.hidrive.strato.com/lnk/FomRBiJv PW: "http://www.ps3hax.nethttp://www.ps3hax.net" Here the link to the TUT: http://www.ps3hax.net/showthread.php?t=40793 And now to the core problem. Here are the GT5 updates für BCES00569 (EUR) in a way better speed than from Sony servers. https://www.hidrive.strato.com/lnk/qzGRBNh4 https://www.hidrive.strato.com/lnk/8HmxBfUL https://www.hidrive.strato.com/lnk/MvGxBE2a https://www.hidrive.strato.com/lnk/5HGRB22p https://www.hidrive.strato.com/lnk/7pmxhF7f https://www.hidrive.strato.com/lnk/oMmRhkHK https://www.hidrive.strato.com/lnk/BOGxh0qC https://www.hidrive.strato.com/lnk/TVGRB1Hd https://www.hidrive.strato.com/lnk/4rmRhhOv I followed the TUT to resign the eboot.bin with 3.41 keys and edit the param.sfo. both files were replaced in GAME folder: dev_hdd0/GAME/. Files in your DISC Folder i.e. dev_hdd0/GAMESZ-ROGERO were not touched as they do not matter for fixing updates. Unfortunately, I get an 800XXXX error as many others here that tried to fix updates. What went wrong? How do ifcaro and others crack Portal 2 or some games that we are not able to crack? Do they have better tools?
