[K3 Note General] Meteordust:
Short tut what I did, worked for me 100% and did it more than ones and yes when turn off/on wifi you get new wifi address when no copied modified nvram wifi files or no used ChameleMac, coz in nvram partition wifi is totally zero's

You need 3 separate programs, SP flash, Maui 3G and SP meta tool, don't try to edit Mac addresses in Maui Meta 3G, use SP meta tool.

With SP flash tool, flash rom like you mentioned, with a APDB and ModemDB folder, I did format flash / download.

After that

don't

start your phone !!, tick disconnect/close SP flash, USB disconnenct

take

battery out.

Start Maui Meta 3G, tick disconnect, USB connect phone

without

battery.

Tick connect in Maui window, flip battery in, phone goes in Meta mode, after 10 seconds or so Maui connects. A window pops up but if not the Imei Download close it.

You start with step 9, tut russians, link Emptywordsss, use Chrome translate.

Select Imei Download, new window pops up, tick change Nvram database and select from modemdb folder the BPGLU_ltg_n file.

Modify your two imei, last number of imei gets automatically assigned, after that select Imei 1 and download to flash, select imei 2 and download to flash.

Close Imei download window

Additionally you can flash barcode, what I found out that's the PN number showed on ROW roms and is the battery serial. No need to flash this, so tick disconnect in Maui, close Maui, USB disconnect phone, take battery out again.

Start SP meta tool, tick disconnect, USB connect phone

without

battery, tick connect in SP meta, flip battery in.

Wait till connect, select AP NVram editor, in new window, read nvram, select from apdb folder first APDB file and go on with I already posted, in left tree select item, tick read nvram, right tree pops up, modify your needs etc...

After modify what you wanted, disconnect and start your phone, this is the first startup after flashing the ROW rom. You can check your imei, wifi, it should be there!!. After that flash twrp and install any rom you like, but don't flash any nvram backup from previous with it of course, make backup of this one, but don't need to tell you that.

For others don't use this if you don't know what you doing, I'm not responsible for mistakes, use russian link from earlier post, translate it to English with Google Chrome. http://lenovo-forums.ru/tutorials/article/561-%D0%BA%D0%B0%D0%BA-%D0%B2%D0%BE%D1%81%D1%81%D1%82%D0%B0%D0%BD%D0%BE%D0%B2%D0%B8%D1%82%D1%8C-nvram-%D1%81-%D0%BF%D0%BE%D0%BC%D0%BE%D1%89%D1%8C%D1%8E-maui-meta-3g-%D0%B8-sp-meta/

If you done it ones right it's a peace of a cake actually and not more then a 10 minute job total. Also no need to flash backup of your new nvram when installing new roms, never did it or needed it. Always still have my wifi,bt and Imei's back after flashing new rom with TWRP.

Hackerpower does not have backup of valid nvram of his phone, have doubt that you can flash permanent wifi, bt mac addresses coz you can only load the BPGLU nvram database in Maui Meta 3G and not the needed APDB database I believe, that's why you need separate SP meta tool program. You 100% sure about that.

Saw your Youtube, handy, does it run on Windows 10 Professional coz I see you still run XP Pro.
