Tons of Newbie Questions (MT6589)

[juweh]

I have a MT6589 device, currently experiencing "Invalid" IMEI..

Tried all known fix such as MobileUncle, Engineer Mode, NVRAM root folder and still fail. Now, I read somewhere here that I need to reformat my NVRAM by flashing... thing is I need to back up my rom first because before this IMEI issue my phone got bricked/deadboot and I spent almost a month looking for solution until I end up paying someone to fix my phone, He did fix my phone because it's now powering up, can access wifi EXCEPT for the IMEI... Now I am planning to take the matter into my own hand by backing up the current rom and flash it..HOWEVER the only way for me backup my rom to PC is MTK Droid tools...I already have the tools and drivers to do the task HOWEVER whenever I open MTK Droid tool, it's not giving me my phone information just he IMEI null------------will continue later because i guess a miracle happened because while writing this i decided to open MTK again to get a screenshot but now it's showing my phone's information..
