So using Jakiman's guide, ive 'load lv' and 'limits 250 850'. That's been stable for a month, awesome...

Now I want to do 900, for the sake of '900' so 'load lv' and 'limits 250 900' and a few minutes in, the phone will reboot. I've tried it about 3 times, and each time it ends up rebooting itself unexpectedly, anything I can do other than give up? Should I be loading a different voltage? ulv? Is my phone a party pooper?

P.S. Thank you Titan, and Jakiman, and everyone else involved...
