A QCN file is a Qpst tool backup file that can be restored using the qpst tool. You need to enable USB debugging and will need to access the hidden menubto change USB mode to diagnostic.

You cannot download one. You have to get another d850 backup the qcn for that phone, then restore it on your phone. Be careful when doing this stuff. If you do not have the knowledge then do not attempt to do this yourself.

Hellomy name is korlan. First forgive me for english mistake i will made that's not my common language.
Here is my problem :
2 days ago i accidently flashed (./flashall.sh) the nexus 5x with the 5 files (hammehead files made for nexus 5)... Obviously it has ereased the bootloader and now the phone won't boot.
I made TONS of research because i can acces to the qualcom DLmode (the ref is 8992);
At this points i'm stuck. How recover emmc and flash again the phone.
Luckily i have another nexus 5X. I have dump all raw rom ( dd /dev/block/mmXXX and got a 16gb file wich coresspond to a raw valid rom).
I was happy but i faced a big problem : How download this bin file to the bricked phone.
I have the tool called QPST wich require a programmer (probably MPGR8992 ) the bin file and a rawprogram.xml (partition table). I don't have thoses files anone know how to obtain it or another way to unbrick this phone ?
thanks a lot hope you can help me inthis situation.
Have you tried flashing the bootloader for the 5x with fastboot?
Sent from my Nexus 9 using XDA Free mobile app
Yes, but I can't boot on bootloader, and so on fastboot mode ...
Its a lg phone , maybe you can turn on factory mode.

Could try some solutions here if not already attempted...http://forum.xda-developers.com/showpost.php?p=67089762&postcount=55 ...have the same issue, as I have messed with the GPT/QC partitions...
To be able to send the raw binaries you do need the flash programmer for this phone, and potentially the MPGR8992 mbn file as well. These two are apparently not available anywhere I have looked. The issue I am running into is that my phone resets the connection to all the tools I have used.

Hi,
I write wrong firmware and bricked phone, then i restore old one but i got empty imei number.
I read about MauiMeta and try to recover Imei number, but i don't have proper modem file (file BPLGU.....). I try with file from k430dsy (http://forum.xda-developers.com/lg-k10/development/lg-k10-k430dsy-original-modem-file-t3481543), but it didn't match. Is there possible to extract it from oryginal KDZ file? Maybe someone have this file.

If you know your original imei nr. you can download your firmware with lg mobile support tool.
What apout lg bridge update error recovery?
Or in case you have your original firmware you should search for mobileuncle tool, there is an imei repair thing for MTK devices.
I mentiuon several times on whatsapp group to make a backup of the ID's partitions before changing firmware.
To restore it now you will need a box now.
Hi,
On which raw firmware version i can get those 2 files. I have deleted them by using command:
fastboot erase modemst1 and fastboot erase modemst2
I am not able to re-locate them in any RAW Firmware, my baseband is Unknown now, it used to be DRACO M...

Instead of posting multiple thread, you should write a detail about what you did, what is working, what is not working and what you are looking for. May be that will help others to figure out a way to help you.

Look no one is going to share qcn file , so atleast if someone shares modemst file which anyone can easily backup and share, baseband can be recovered and then i may get back my network.

Use imei write tool or efs write tool. Imei and serial no u can get under the battery or in the mobile box.

Modem bin or non-hlos bin u will find in stock ROM. Flash it first and write imei,
Hi,
I recently tried to flash qcn on my OnePlus 7T and it seems that I lost efs data (some sensors aren't working now).
To extract qcn or xqcn file you need to enable usb diagnostic port (in phone app dial *#801# and click the second and fourth buttons).
Doing so will make your phone detectable in Qualcomm softwares.
To extract qcn, use QFIL and click Tools>QCN Backup/Restore. In the field "QCN file path" write the path to the directory you want to save the backup, and also write the name of the file that will be created. Then click Backup QCN.
To extract xqcn, use QPST Software Download, and go to the Backup tab. Click Browse to select the destination for the xqcn backup, and set a name to the backup that will be created. Then click start.
Doing this process is quick and should take approximately 5 minutes if you already have the QPST software.
In case you need it, I have the installer from Qualcomm for QPST 2.7.480 :
http://www.mediafire.com/file/nm0zlac003tn41j/qualcomm_qpst_setup_2.7.480.zip/file
Also you have to know that your IMEI will be visible in these backups, and you should remove them using an hex editor to replace it with some random numbers or zeros before sharing it with me or anyone.
If you need informations on how to find your IMEI in your qcn or xqcn backup using an hex editor, I will explain it in this thread too.
Thank you
Are you saying with these same methods you lost efs data or you did a mistake while flashing ?
Thanks @egekonuk for your reply.
In fact I was trying to flash international rom version on my TMobile Oneplus 7T by editing MSM download tool (using x64dbg which is a software sharing many functionalities with IDA Pro).
I did not managed to flash international but yes, I lost efs in the process.

Just curious why you didn't do the other posted method to go from TMO to international? I did the other method and it worked out just fine. Of course I don't know if that very friendly person is still doing unlocks or not.
Is there a difference between the QCN and XQCN between ROMs?
@amcferrin90 yes I didn't mentioned that but it's because my device was not SIM unlocked by T-Mobile. I bought it on ebay and I was not aware it was not paid off, and seller refused a return.
If I was SIM unlocked, I'd be able to unlock the bootloader and flash the international rom using fastboot.
I did not understand what you meant about qcn, xqcn and roms.
To me, qcn and xqcn are different because xqcn backups are larger than qcn ones.
I think xqcn contains some efs data, but I'm not sure about this.
Would you be ok to make a xqcn backup and share it with me?
Thanks
I also need a backup of QCN.(please)
Hi, I tried to unlock bootloader by using Qfill. During the process i backed up the AFL-A file and it creates .bin exten. After that i erroneously pressed erase of AFL-A file. Now the problem is i had AFL-A file backup in .bin exten but I don't know how to restore that file using qfill app. Thanks in advance.

This should give you a good idea of how to re-write the partitions!
Sorry, maybe I'm referring to the wrong place, but I did not find another post related to qfill. My question is: Is it possible to replace the APN settings file through QFILL and if so, what is the name of this file? I have lg v50 thanq 5g. Thank you!

APN settings can be modified under your network settings.You won't need Qfil or anything for that?What are you trying to accomplish?
