Ok , I have 2 slash 4x4 trucks. One truck has the mmp and novak ballistic 550 5.5 motor and the ther mmp has the vxl 3500 motor. Using a traxxas 2.4 radio.
Whatever I do for one I am also trying on the other which leads me to believe I have a esc post update related issue.
A couple weeks back I got into the groove and decided it would be good to update the software version, I mean what could it hurt since it had been all winter so a few versions wouldn't hurt or so I've thought so far.
I upgraded both esc's to 1.32. During this upgrade my laptop would freeze after the install when I updated the firmware. This was on Win 7 starter edition. I eventually got it to upgrade and set all the settings for lipo cutoff (3.4) and left alot as it was otherwise.
I went to the ball fields with one truck Fri night to drive while the son was doing baseball practice. I had to bind the tx to the rx so I did it. I then got my smart phone out to make me smart and read up on the mmp manual that I had downloaded. Ok now I'm smart because I was on the smart phone so I proceeded to do the calibration per castle manual. Well that's where all the trouble started. The yellow light flashes, I have steering. I played with the steering and throttle trim knobs slid the 50/50 knob over and then back. read all possibilities even rebinded the tx to the rx several times through this process and still just a flashing yellow light. I even tried different batteries to be sure I didn't have something wrong, 3 different batteries to be exact.
I came home after baseball practice. Tried it on my other slash 4x4 same results. I then decided to make sure it wasn't the tx and Bound the tx to my emaxx rx since I had upgraded the emaxx esc 2 weeks ago also. I calibrated the emaxx esc no problems whatsoever and it was fine.
Tonight came around at about 1230 am central time and I decided to tackle this task again and decided to use my windows vista pc. I upgraded the castle link software, sent it to the mmp esc's . checked and the escs were at ver 1.32 , set all settings.
Powered up 1 truck at a time, bound the tx to the rx and proceeded to calibrate and the not so forgiving yellow light again, WT#$!@%^ !!!!!!!!!!!!!
So I tried the other truck, same problem. Reverted the software back to version 1.30 and 1.26 and went through all the steps and guess what the

YELLOW LIGHT STILL FLASHES

!!!
Does anyone have a clue on what can be wrong ?? These esc's are almost a year old and have less than a dozen runs combined due to medical problems keeping me away from the hobby over the last year and me having so many trucks they all get their turns when I have a chance.
Any help would be appreciated as I have a SC edition esc that I have thought about hooking up that I just bought 2 weeks ago over the net and I am very fearful to install it let alone upgrade the software version...................................
All help will be appreciated. I hope if I'm slightly past the 1 yr mark that castle will help me out. I have alot of castle stuff. I do plan on calling castle on Monday right away unless I get this solved. Thanks !!!
