Sad story about flashing radio from Meizu MX3 to MX2



I've found that Meizu MX3 and Meizu MX2 have the same radio chip - intel xgold626.
Latest MX2 version is 425, but in MX3 is 435. I've compared firmware and found that it have the same files. As I have root on my MX2 FW 2.4.1 I ran IMCdownload flasher in terminal. After this I've lost my IMEI and SN :)
First rescue step was reflashing MX2 radio back. It was successful , but IMEI was not returned. With no IMEI I can call 112, but phone won't register in network perhaps because of default IMEI 00499901064000

For now I did many things and found that Newman N2 have the same radio and there is manual how to repair IMEI & special intel phonetool for XMM radio chips:

Intel PhoneTool requires serial COM interface , but I can't get it from MX2. Perhaps it might appear in USB ACM mode.
MX2 export only theese USB modes: MTP, PTP, RNDIS (USB network tethereing) , ADB (UDB debug).
So I can't turn device to "Download Modem" mode as described because there is no *#3646633*# code in Meizu, so I can't go further.

Engenering mode *#*#4636#*#* have buttons "Enable Modem USB" and "Enable AT commands" but after pressing it nothing happens.
And there is no *#3646633* command.

Any ideas how to get modem COM port in windows?

PS. I've read about xgold626 Hack-Pack Content in http://forum.xda-developers.com/show....php?t=1483053 , but links is dead. I'll be appreciated if someone share it again.

PS2. Here is no authorized service centers Meizu :(
