Solved Unfixable 0102?

[NGU iTz Christy]

Hi
I have a exploitable xbox that has 0102 error.Im wanting to Jtag it so Im trying to fix it ,I reflowed it with a heat gun twice already and did the xclamp fix.For the reflowing, I reflowed the back off the board on the low setting(316 Degrees C)for a minute and the top off the board for 3 mins on high(528 Degrees C).Then I put it all back together and I still have 0102 , Iv'e noticed if I tighten down the gpu very tight it turns into 0022 error.Reflowed twice.
Has anyone got any ideas I really want to get this fixed?
Thanks

reflow it using a re-work station

or reball it

its a GPU error

Is there anything else I can do other than reballing ?

If you weren't using thermocouples to monitor the temperatures, you don't know if the solder actually reached reflow or not. You mind as well be doing it with your eyes closed.

I don't think you reflowed your board. If you did, your board would warp like a potato chip since it wasn't being heated on both sides at the same time.

To perform a proper reflow, you must have a preheater on the whole time. The bottom of the board should get to at least 170-180C (190-200C is preferable).

The thermalcouple on the top side almost touching the GPU (side facing opposite to the CPU) should get to 215C for Xenon/older Zephyr boards and 220-225C for newer Zephyr, all Falcon, and all Jasper boards.

Just get it professionally reballed. Reflowing with a heat gun is bad for the motherboard. It will give you worse problems later on down the road.
