看图中标出的就是AUD_CLAMP的位置,具体接法是:如果你的机器版本是Zephyr或falon(带hdmi接口的),如果在启动的时候不定时出现E79(多启动计次还能启),那么传统的JTAG接法(电阻或二极管的接法)可能会导致E79,你需要做的,只是把其中一根接到前面板(无线发射模块)的那根线焊下接到AUD_CLAMP的位置,然后用jtagtool2.20重新合成12611的固件,在合成的时候注意选择“AUD_CLAMP SMC”这个选择框。我就是用这个方法解决了我的E79。唉,时间过得太久了,言语表达不清,转载一篇国外的帖子自己看一下吧:
UPDATE (Nov 19, 2010): So I believe I fixed my Zephyr's random E79 errors. I changed the soldering point of the Yellow wire from the JTAG QSB (that originally went to the front ROL pcb) to the AUD_CLAMP point as instructed in the tutorial above. But then I just used "JTAG Tool" (ver 2.20 by coolshrimp) to build me a new Freeboot.bin with the SMC fix by simply selecting the checkbox "AUD_CLAMP SMC" and then I had it create me a new .bin, which i then flashed to the NAND. Everything seems to be working fine now, granted I have only turned on/off my xbox about 10 times, but each time it booted up quickly without any E79 errors. Maybe someone can verify that this indeed is a viable method, especially since the new 'JTAG Tool' updates you to the 12611 dashboard (and you can bypass all the 'building the 9199 freeboot image' crap!! Just let the program do it for you!) I will update this post only if i find that i begin getting E79 errors again; if not, then that's means its still working for me (and hopefully it works for everyone else too!) |
