Hello, battery in my N950 was for 3 years dead and I finally brought a new original Nokia BL-4D. I put it into my N950, it light up but showed me only error message that Device not working properly and that I should contact Nokia Care. There is _no_ security error message which was visible after messing aegis. Note that device worked fine 3 or 4 years ago with previous battery. It had official PR 1.2 release. Is there any way to make N950 working again? I have tried to enable R&D mode and disabling lifeguard reset but it had no effect.
