Hello,
I move your thread from XDA Assist to the correct section.
Flash the latest Firmware from here...http://forum.xda-developers.com/show....php?t=2729173
6.20.651.3 Modified Firmware...removed boot & recovery (fastboot flashable) for non Harmon Kardon
or
6.20.654.3 Modified Firmware...removed boot & recovery (fastboot flashable) for Harmon Kardon
Follow the instructions in the thread above to flash correctly.

Then run the matching RUU and you should be updated to MM.

Do at your own risk...please read and understand what you will be doing before starting.

Sidenote you can use either version because you are s-off and supercid. If you do indeed had the Harmon Kardon Edition if you decide to use the non H/K firmware and RUU you may loose some audio quality.

No, using official RUU should not block your sim. However if the battery is very low or the phone gets really hot, sometimes the phone blocks the Sim.(you will have to downgrade back since you are soff and unlock again the sim)

Regarding the step-by-step, it's there in the thread @Sloth linked in his reply.


Side note to read for entertainment: Something which I do and is DANGEROUS is place the phone ON a SEALED ice pack, and place some layers of tissue papers between to absorb any dew precipitating on the ice pack. Do this at your own risk and CLOSE observation. This may seem funny or ridiculous, but the whole process might take 30-60 minutes, and if the phone is plugged in and gets hot, it can even damage the battery.
