I'm so proud of you guys but there seems still no solution for band 4. I come back to this guide everyday and a little bit disappointed each time.

If you come back every day why didn't you read that the guy figuring things out is on Holiday.

I just thought of this, could we theoretically trade EFSs? If I have an OP3 US, could I find a person with a chinese OP3 who I trust and trade EFS backups with him? Would that make my phone be able fo connect to Chinese bands? This would also solve the IMEI problem because once the transfer is complete, there still remains only one device with those IMEIs.

If this is possible, I'd love to find someone on this thread with a chinese model and trade EFSs with him. Feel free to check my profile if you think I'm a scammer or what not.

As I'm rather useless I initially forgot to back things up using the full qcn. I used the full unbrick guide and your IMEI gets restored using that (luckily??) So if you swapped there's no guarantee of keeping it. Unless EFS isn't restored ?

I'm having a hard time deciphering the message you tried to convey... Why would I brick my phone? Or are you offering your candidacy for the trade?

Haha sorry I'm tired. No I meant when using the full .qcn from original instructions I forgot to backup. Therefore I used the unbrick guide and reset my phone and the IMEI reset to my originals thankfully. So what I meant was if you swap with someone there is always the chance either of you could reset to their original and you would both be using the same IMEI. But I'm just a user following instructions so I am not knowledgeable at all on this topic.

Of course one of the users cod revert to the old IMEI. That's why you have to fully trust the other user you switch EFSs with, and make sure both parties understand that if they want to revert to the old EFS, they must notify the other that they have done so.


My offer is still open if anybody would like to trade EFSs.

Maybe you can be happier by avoiding this thread? Also I suggest you to donate to devs so you will be less disappointed.

Hi i want asking, must flash OxygenOS Marshmallow version right?
So if i unlock band 5, and sideload OxygenOS Nougat, it change to default?
Cause webe cellular need Band 5 (OnePlus 3T no issue cause support band 5)
Want confirmation, if no problem will do this. A little bit scared

Somebody can check the QCN on the presence of IMEI. It's backup from my phone - A3000cn.

 

[drumbo1]

I found only one IMEI.

Are you restored the my backup of QCN to your phone?
