RE: In Search of 15C+ ROM image - Benoit Maag - 02-13-2023 01:56 AM Thank you J-F for the memory patch and DMH for a great video showing the install. It worked great! Is there a patch to the 04-15-11 firmware to make PSE work (rather than go back to the 08-19-09 firmware which Bob indicated has its own bugs)?

After reset, it showed “-Pr Error”, and the CHS button was invalid and the switch was disabled. Still display - on the front (Now FW: 2011-12-12,ChE:4903h), That's why? Has anyone tested it? It seems this file is wrong。 [attachment=13368] [attachment=13369] [attachment=13370] [attachment=13371] [attachment=13372] |
