Hey everybody.
At first I'm going to explain my problem.
I'm living in Iran,middle east and using xiaomi redmi note 3 pro.
I need your QCN backup file. Here my phone xiaomi (all of the models) can't connect to internet data via 4g+ because it can't aggregate band 3 and band 7 together. for this situation i have to modify own qcn file. As we know C9 pro and redmi note 3 pro use similar modem hardware. Maybe it can be useful.
If you don't know how to backup qcn file I will give you a instruction.
You must dump a ESF partition or qcn file from QPST app.
Tnx.
Is not there anybody here ?
UP!

That's for S3. Maybe not working for note 3.
Install Phone Info. Check and browse what is your phone's firmware within the app. Then flash with odin.
See if that helps.

Why would any user give you an NV backup that contains their IMEI potentially allowing you to clone their IMEI ??
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.

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

did you get the QCN file? could you share it?
I also have a ZTE AXON 7 A2017 CHINA
@RBSonic: I would be glad to cooperate, but I will need to know a few things:
1. What software is needed to make the backup
2. Instructions on how to make the backup with said software
3. Assurance that the backup I'm providing won't contain personal info like legal name, phone#, IMEI/EFS, etc.
I too am interested in unlocking LTE bands for the Axon 7. I have an A2017U, not G. But any info I provide might still be of use.
Thanks!

1. You need QPST and QXDM software.
2. There are many instructions in Internet. You find it easy.
3. Yes, there is personal info in qpst backup (IMEI, may be phone nummber, but no name). It must be delete, before you post this information.
May be it can help other users, but now I have not time to work with Band unlocking. May be later. Sorry.

EFS Backup of Redmi Note 7 Indian Variant
Hey there, here's my device's EFS, but my RN7 is not the global one which comes with a 48MP Camera, it only has a 12MP Sony IMX486...
Hope it still gets the job done...

Need EFS backup for redmi note7 pro
Dears, hi
I accidentally restore a wrong qcn backup with qpst tool during the IMEI repair procedure of my xiaomi redmi note 7 pro (violet) and all of my networks suddenly stopped working (WIFI, LTE and Bluetooth) after days of searching I successfully restore my Bluetooth and wifi functionality by restoring the shared EFS Backup of Redmi Note 7 in this post. but my IMEI number still remains null !
I believe its because the efs backup that I used isn't for note 7 pro.
i tried to restore my IMEI Numbers by qpst tool but every time the result is same, a soft break! and I must restore efs backup again and flash custom rom.
So please! anybody has the efs backup of violet or any method that can help me to restore my IMEI numbers?
Regards

Not sure what QCN backup is.
But the file that tells the phone its IMEI is corrupt. Getting a copy of persist from someone else will give your their IMEI which I don't think they or you want you to have. You've got an expensive brick

Don't know how you would go about repairing it though I did see results in a google search. However, on the OnePlus 7T Pro 5G McLaren, your IMEI number can be found on the back cover of the phone under "McLaren". If you weren't looking for it and/or use a case like most do for this slippery phone, you'd never see it because it's grey and blends in with the McLaren Pattern on the back.
