Hello,
I received my Oneplus 2 today and it does not support the LTE Band 3. It`s the north USA Version and i would like to ask if anyone figured out a method to unlock the LTE Band 3 (1800mhz) . It`s because the Hardware of the Oneplus USA Version is the same like the European version.

That would be amazing if some one could figure that out. But as I did my research it seems that it's not possible that there's a hardware difference.

Should be the same procedure as the HTC M9 since they're the same processor. And for the prep work (drivers and enabling the modem diag mode) as in this thread for the OnePlus One.

Do the changes to the band stay after rebooting or upgrading the OS to a newer version? I wanted to unlock band 3 as well on my OP2.
I haven't tried writing the modem configuration yet to see if it sticks or not but was able connect the phone and read the configuration from it by following the instructions from the 2 posts I mentioned.
Say if you got Chinese oneplus 2 and changed software on it would it work on bands 20 I've seen this question asked before but can't find the post
Sent from my LG-H815 using XDA Free mobile app
anyone found a way to unlock band 3?
Have a look at this post
I suggest you to keep 3G instead of LTE because battery draining is so faster under LTE Mode. If you stay a place that have a poor LTE signal,that would be your battery killer.

Hi, this research includes some whitepaper research?, Does it actually has different hardware?, just wondering if someone knows this by solid proof?
To know if there is hope for us (Buyers of wrong OP2 version )
I'm using A2005 usa model in India and I'm unable to use it on Airtel 4G in India. When I spoke to the OnePlus customer service they said it will need to replace the motherboard as it's a Hardware issue. I'm waiting for the motherboard to arrive from china as they don't have it yet in India. So basically it's a Hardware issue on oneplus 2 unlike it's ancestors.

They will do it for free? Or what is the charge?
Ok, guys, I`ve unlock NVram to write. Now I can save any values to change enabled bands.
Intruction:
Requirements:
OnePlus 2 with TWRP and rooted.
QXDM Pro, drivers, etc, as described here http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
Stock ROM OnePlus2Oxygen_14_OTA_011_all_1512111634.zip.
Attached file.
Just unzip attachment and replace file in ROM OnePlus2Oxygen_14_OTA_011_all_1512111634.zip, in RADIO folder. Flash via twrp.
After boot you will see warning "NV backup corrupted" or something like this, dont worry.
Use QXDM to change band as you want, reboot and check. Voilya. But LTE will not work, because it is hardware issue, lol.
A few words about attached file. I just unzip this file from stock ROM, search AC 1Ah (6828 little endian) and DB 08 (56072, US LTE band) together and replace DB 08 with DF 10. Dont ask, what I did, I dont know, lol. But it is work.

There is easier way to do that without corrupting the backup.
Simply change the value is QXDM.
Then in the phone dial *#268#
Press the NV parameters
Press the Static NV Force Backup.
This will copy the new values to the backup, and they will stick later on.
BTW, to be on the safe side, make sure to backup your dycnvbk, stanvbk and EFS.
Not working for me. Cause com.android.phone crash after dial. May be because my backup is corrupted. Later will try with stock backup. But thank you anyway.
I am using the stock image with the stock phone app.
I am using Mokee, chinese AOSP firmware. BTW, I just erased nv backup partition and keep playing with nv ram. Hope will not brick my phone ))
What version do you have? US/EU/CH?
In case you have EU, cab you PM me with qcn of your device?
Unfortunatelly I have US version.
I know a way to add bands in snapdragon 801 (i did in xiaomi mi note) never tried in OPT since it has all bands i need . but it should be the same. Search google for adding bands in mi note
These are guides for unlocking additional basebands on Qualcomm devices I want to try it on yotaphone 2 but I thought I would ask for advice first.

That's would be really cool for our YD206! I always thought that the lack of some bands was physical, so it's not and they are present in the motherboard?
Have someone tried it?
I found something that might be useful to the OP: http://forum.xda-developers.com/google-nexus-5/general/radio-enable-lte-band-3-nexus-5-d820-t2928561
edit qcn file
It looks like only way to modify, add LTE bands is by modifying qcn files.
It is working procedure for Oneplus3, for example
https://forum.xda-developers.com/on...ck-additional-lte-bands-t3519563#post70099218
Does anyone can do that? To add band 17, for example? we can supply original qcn.
what are the risks? why all are asking and no one do something? OR we all need a guide special for YOTA
I have been looking for a custom ROM with VoLTE enabled but quite disapponited that no dev could present one. LOS apparently have not even thought about introducing VoLTE on i9505 LTE international version though I myself could manage to get VoLTE working - that is for the only VoLTE provider at present in India namely Jio - via stock ROM after experimenting with the method described by @dhiru1602 on this forum but never found anything else. With LOS the VoLTE provisioned flag is not even enabled and so none of LOS based ROMs could provide a way for VoLTE.
One can find my alternate method which I used to modify a stock ROM for VoLTE at the link below. I have been using it since the day I posted it without any problem.
https://forum.xda-developers.com/galaxy-s4/general/volte-i9505-international-jio-easy-t3657679 using sammobile website for the stock FW and YouTube for necessary firmware and files.
I am more than sure some dev will take it up to provide a solution. Will highly be appreciated and a BIG thanks in advance. Hope to see a FW soon.
I have a friend who purchased a Zenfone Max M1 Pro made for the market in India (and maybe elsewhere) for use in the US. He did not realize that the bands used overseas would not be helpful in the US. I am trying to help him. He is on T-Mobile and really needs LTE band 4 so he can use his CellSpot device at his home. Sadly, the device he bought lacks this band.
I have been reading and trying several things since I rooted this device. First I tried the well documented approach using the QXDM utility. It turned out this did not work on this device. Not entirely sure why. But this user <https://forum.xda-developers.com/showpost.php?p=79713339&postcount=3> claims it is because the phone in question "does not have a programmable radio firmware" and "Network parameters are pre-installed in mcfg_sw.mbn files, also the per carrier volte parameters are embedded in this folder". He then says "mcfg_sw.mbn files can be deleted and installed by QFIL in QPST. "
So I am willing to try going this route. In looking around, it seems that users looking to change their phone's Qualcomm configuration have been finding users with "compatible" phones online and getting ahold of their files of this type and installing them + some additional properties changes. Sadly, Asus did not make a version of the Zenfone Max M1 Pro for the US market and so I have been trying to find another Asus Zenfone that seems possibly compatible from which I could try to do the same.
This brings me to this forum and post... In looking at the specs, the Zenfone 5q and the Zenfone Max M1 Pro seem to share many common features. It is true that one uses the Snapdragon 636 while the other uses the 630. But from what I have read, they employ the same modem. So I am hoping that I may be able to succeed using files from the 5q.
So I am asking to see if some rooted (you need to be in order to access the folder/files in question) 5q owners/users might be able to help. On the M1 Pro, the files are all located under this folder: /firmware/image/modem_pr/mcfg/configs. So I am guessing/hoping that the same location will be used on the 5q. It it is, could someone possibly zip up the contents of that entire folder and make it available somehow? I could then compare what you have to what I have here and maybe try some file swapping.
Any other tips/suggestions are always welcome too.
Thanks
Hi,
I own a Samsung Galaxy J5 Pro 2017, Model SM-J530F, which I bought from UAE. The specs on the box shows it as a 4G LTE device. I am quite confirm it does not have VOLTE in the settings. Now that I am using it in INDIA with Reliance JIo services, I badly need VOLTE functionality on this phone to make it possible to make & receive calls. Is there any way to add VOLTE functionality to it ? Any solutions from our developers ? Please don't ask for flashing a custom rom!
Thanks in advance!
( Though I can install JioCare app & use it but the app is not available on Wifi, works only on Jio LTE ( Jio Mobile Data ) & forces to keep the wifi turned off permanently for the functionality. Actually Jio provides 4G VOLTE only connection & it is not backward compatible with a 4G LTE only device. For that Jio uses VOLTE layer from within their JioCare app to support a 4G LTE device )
This phone is still quite smart! Please help!
Looking into your device model, it seems like there was no India release. In situations like this I would recommend flashing the INS version of stock firmware but since it doesn't exist for this model, I honestly think your only option is to root and edit the CSC features file yourself which can be annoying and quite honestly very long process.
You could also attempt to just flash another region and hope that it has VoLTE included. I don't know if this would even work though.

Thanks for the quick response! I really appreciate it but I was just thinking if there is any other way ? Jio uses VOLTE layer from within their JioCare app!
Hi,
If I understand it right, I have to use CSC file & not the HOME_CSC file to see any changes that I desire, right ?
Thanks in advance!
