Your device is bricked which is why it cannot be seen in Windows because it cannot enter Mass Storage Mode. You can obtain your HWID via 7ToWin in preboot [see point 7 of the linked thread by catymag]. It's essential that you check the HWID because there are 2 different chips in 14xx. The most common is HWID 0972 but the MediaTek chip models are HWID 1104 with different firmware.
So, check your HWID. Make and use the cure3 fw as per the tut thread linked in point 8 and then post again either here or in the cure3 thread if you need more help. This thread is confusing to you because amos1 was not able to successfully completely cure his unit. His experience is not typical because even after loading the cure fw his unit couldn't enter MSM.
I suggest you stop trying to make sense of this thread, and just thoroughly read Post #1 of the cure3 thread and then follows the steps in it before posting further. The 1490 of amos1 had to have drastic measures taken for it to be accessed by Windows and made usable again. Most bricked units don't need any more than 'curing' and removal of corrupt files or reformatting correctly with RMPrepUSB.
