EFSs didn't help you. I have tried it.

I'm not recovering qcn in my phone. I checked with imeirebuilder. This program always gives me good results. When checking qcn of OP3 normally gives me 2 IMEI number.

What do you mean? Why?

Okay, why do you need the EFS? I restored EFS from the A3003 to my A3000cn, and NvRam was empty. Maybe I didn't understand you correctly

That is what I meant for us to do, but if it doesn't work I'll give up that idea.

I went through this entire thread, and if I read correctly, right now there's no solution to unlock band 3 on the US variant of OnePlus 3? where I live theres only LTE band 3.

Correct and to be honest..... There is no complete solution to unlock ANY band (without consequences or unwanted side effects).

Hi all,

I know that maybe this is not the right topic or forum channel. But if someone is interested to change their Phone to me, please let me know. I have the OP3Chinese Version with Oxygen OS accepts 1,3,5,7 LTE bands.

I need US Version with Band 4 unlocked.

Regards

OnePlus 3 A3000CN only supports LTE 1/3/7, luckily where I live LTE is on bands 3 and 7 so no problem. When I travel to rural areas my carrier uses band 20, there I have no luck and fall back to 3G.

Waiting for improvements to the guide and further research progress.
Thanks everyone!

What OxygenOS version you flash? A3000 dont have band 5, you can check specs in OnePlus website. I'm use OxygenOS Beta 10.
Wanna try this method on Nougat, but dont know where to start it and boring back to Marshmallow ?

Last time I checked, the Chinese A3000 supported only 1/3/7.
I wish we could get 5 along with these, that's all I need lol.

Hello,
I wanted to ask if this guide-solution will be possible to work on other devices. I have Oneplus X (US version) and I want to change band and frequency to make it work with LTE networks in Europe
Thank you in advance.

I have one plus 3 US version,
Can I use A3000CN base to unlock all TDSCDMA&TD-LTE band?

I have a trip to china next month, it would be great to have all China bands if possible.
