Hi.

I have a BSOD on one unit here, and since I suspected the BGA-array under the SoC to be the problem, I attempted a reball. I am pretty sure it was succsessful, but how do I verify this? It will go to RCM, and it is possible to inject payloads, and I see the menus and other graphics on the screen when doing so. Trying to boot in normal mode yields the BSOD. Does this verify that the CPU is functional and that I did an ok reball, or could there still be problems with the SoC? I would say the balls on the SoC looked flawless and was very precicely on, before installing it. Could there still be points that are not connected resulting in it not being able to boot up, or could it be other problems that I should look into (like eMMC?

The reason I suspected the SoC was that the machine would quickly crash as soon as it was exposed to minor movement. If laying completely untouched it could run normally for a long time.
