Have you received any reply on this regard?
The NVRAM variables are not to be modified unless directly instructed to do so as incorrect values can cause unpredictable damaging behaviour as well as potentially damage the device.
Why are interested in those two variables?
Not sure if you are asking regarding my reply or regarding wcurrier's comment. In my case, there is a board redesign and there is also a change on the Broadcom chipset. We are in the middle of validation and part of it is veryfing EVM which is not as good as expected. The intention is to update power and/or country code in order to achieve a better performance.
Thanks for your reply, nikvh
