The temp sensor is not working properly, maybe because it is shorting out (2 bridged solder balls).Or it is broken, then you have to cut the trace...

Can also be HANA related on HDMI xbox's.

Had 1 in that was freezing, reflowed gpu and went to 0030, cut temp trace and
was still the same, replaced GPU and still the same, reballed CPU still 0030, so
i re-flowed the HANA as a last resort and BOOM!!!! green lights

so 0030

I have found a cold solder on pin 73-74 on the ANA Chip. I soldered the pins and
the problem is solved.
