You have to put inside a Sim card, input the MCK, then after phone ask for NCK, put out the sim card, repeat the process and now will give you NCK code, is 5 credits for MCK and 5 for NCK, total 10 (That's what I had figured out)

dolores garcia · 05-11-2021, 17:58

Were do I get the NCK code, if only shows the MCK?

Z3X · 05-11-2021, 18:09

Hello. Double charged credits for MCK refunded. Insert sim, enter MCK, close NCK request window and continue reading NCK.

Solved!, thanks for the support.
what I did was, remove the sim card, click on UNlock (UploadMode) when the device reboot to "Modem Crash" mode after a secconds rebots normaly, I put the simcard quickly and enter the MCK code I got, and then The Z3X prompt correctly the NCK code.

Thanks
