[OnePlus 2 General] aurfawce:
After reading through the OPO thread and someone confirming they saw bands unlocked for their OP2, but could not test if they are working as well as reading through the OP3 and similar threads with our processor I finally delved into trying this. Here is the quick guide of how to do it. Sorry if there is any confusion I will try my best to make it concise as possible. This is my first time writing a guide up for XDA.

I have not been able to test each band to confirm it's working, but it is showing up in Network Guru. I am on AT&T so I only unlocked AT&T bands (bc that's all I care about currently and it makes it easier for me to test)

I WILL NOT BE HELD RESPONSIBLE IF SOMETHING WRONG HAPPENS TO YOUR DEVICE BY FOLLOWING THIS GUIDE!

Here is the OP3 thread I based this guide off of and credit to all those mentioned in there as getting this far would have been impossible without them: https://xdaforums.com/oneplus-3/how-to/guide-unlock-additional-lte-bands-t3519563

OKAY:

PreReq's:

1. Rooted

2. TWRP or like

3. RMT Storage patch from OP3 forums: SEE POST BELOW!

4. DFS Explorer - Find via searching XDA, again checking OP3 thread or OPO

5. ADB installed (whether that be minimal ADB or like from other toolboxes out there)

6. QPST - Check forums for download

Guide:

1. Put phone in MTP mode if not default (Some default to charge mode) Just go to status bar and press the charging mode to change to file transfer

2. Place file from PRE-REQ #3 in a folder you'll remember

3. Reboot phone (or shut down) and when coming on hold Vol Down+Power for a few seconds and let go

4. Boot into TWRP

5. Backup (If you don't have a backup of EVERYTHING at this point, probably a good idea to do so)

---If you do take only EFS

And install file from #3

6. Restart into System

7. Open up your CMD and run this ADB command :

This forces it into DIAG mode, check your Device Manager to see if you see a port connection displaying a COM PORT.. IF NOT, you need to install drivers--Search thread for drivers, likely will be find in original OPO or OP3 thread.

***********THIS SECTION IS PURELY PRECAUTIONARY*********************** SKIP TO 11 IF YOU WANT

Purely precautionary we did not have to restore any QCN as they do in OP3 due to encryption:

8. Install QPST, open QPST

Now fire up QPST and go to "Port" tab, and choose "Add New Port" ,

9. On "Serial/USB Port" tab, unchecked the option of "Show Serial & USB...bl bla bla" option, you will see your phone listed there as a "COM#" (# is a number depending on your PC) choose it, and click "OK"

10. Now choose "Start Clients" from the Menu tab above, and choose "Software Download"

**********************************************************************************

11. CLOSE QPST. Open up DFS Explorer, when the signup option comes up it is up to you whether or not you want to register for an account (Good to support them since it's a good application) If not, press the X and the app will be there

12. You should see your PORT listed as you did on QPST. Double click on it (If you can't; confirm QPST is closed otherwise you won't be able to connect to the port) You should see it turn green and highlighted ONLINE if you successfully connected

13. Go to the "Band" option then click on "LTE"

14. Press READ; Give it a second and you should see all currently enabled bands listed; If you want to compare you can go to "Network Guru" and press the 3 dots on the top right and press Band Locking and then press LTE.. Should list the same ones

15. Check the additional bands (Just because it says it's enabled, doesn't mean hardware wise it will work due to chipset hardware limitations; This is why as you all do this if you can confirm which bands for you connected and/or didn't connect we can keep a running list.)

16. Press "Write"

17. Since we're in Demo mode it will count down and then in the LOG box you'll see operation successful

18. Restart the phone at this point and disconnect the cable

19. Wait until it boots up again and go to "Network Guru" press the 3 dots again and go to Band Locking and you should see the new bands listed

*If you don't press the 3 dots and press Clear forcings and it'll prompt that a power cycle may occur; That's okay, let it, mine did, wait until the phone comes back up and repeat 19 and the new bands should be listed.

20. LET US KNOW ON THIS THREAD what bands are working, what aren't. It will allow us to further play with the device to discover if there's limitations or if further editing is required like in the OP3.

*Please press THANK YOU if this guide was helpful.

**Sorry for the missing of some info in the guide! Seems when I added the HYPERLINK it removed most of the other text before it so it started at #4 instead of the remainder of #1-3
