I know this error is rare and I am probably the only one who has it but maybe somebody can still help me. I recently found my old CECHL04 with an RSOD in a box and thought why not give it a try. It still had Firmware 3.15 on it so I Updated to OFW 3.55. Then I fixed the RSOD with 355-NOTHEROS-RSOD and the rsodfix.gnpdrm.pkg. After that I installed 3.55 OFW to check if the RSOD was really gone. Everything worked fine. Then I installed Kmeaw 3.55 and Multiman did a Nor Backup through Multiman. Everything still worked. So I decided to upgrade to REBUG 4.70.1 REX EDITION. I did this as described - the usual way through System Update and not the the revovery menu. Installation went as it should no Problems no Errors. Rebug 4.70.1 works fine as far as i can tell but Everytime I try to Install something load a game or a Programm. It gives me the Error Code 8001050F. I googled it and tried to reset the Time but that did ot work. Anybody got a sugesstion I am out of ideas.
