Need EFS backup from V405QA

Hi guys, for developing unlock of Sprint v40, we need EFS backup from unlocked model V405QA (to compare some things between models).
You can do it by QFIL and QPST tools (to eliminate possible bugs)
Turn on Diag mode: In dialer *#546368#*405#, type 000000 in service code, then press SVC menu -> Port Check Test -> Enable.
Manual for QPST: https://forum.xda-developers.com/redmi-note-3/how-to/guide-qpst-tool-backup-imei-nvram-t3455297
Manual for QFIL: Start QFIL. Open Tools -> QCN Backup Restore. Click Browse and save it in cozy place. Press Backup QCN.
After finish you should see: «Done downloading the qcn file: C:\temp\00000000.qcn» and «Finish Backup QCN».
Manual for NV-items_reader_writer: Set port, click checkbox right after 000000, click Connect, Click Read button right after Connect button, click Read in main window.
Dont forget to turn off Diag mode after.
Many thanks! Your help for community will be greatly appreciated.

Hi.. i was wondering if we backup EFS from Sprint unlocked and restore it to Sprint locked will unlock the network for worldwide sim card?
Would it do any harm or changes to Sprint locked v40's IMEI?
I currently owned a Sprint unlocked LG v40.. bought it from Ebay, put in my Indonesian simcard and works perfect.. 3G/HSPA+/LTE great

Probably yes, with crossflashing unlocked firmware it can be big win for locked sprints.
IMEI will not change, we are searching only for items that locking network to sprint.
Im away till 11 march, but if I can contact you and help with backup, it will be great.

if I backup EFS from Sprint unlocked and restore it to Sprint locked, will this method unlock the locked one?

I can get the efs from an unlocked sprint lg v40 can also get the locked one if you need it

So the job is to get both sets of efs locked and not locked then compare and take what makes the phone unlocked and copy that info into the locked efs then write back?

What about nv items? Just like samsungs j727p is unlocked nv items will be easier then doing the whole efs system.
I can test anything you want not afraid to brick

No.
I have crossflashed v40 with QA firmware, but EFS is not changing while flashing firmware. Network lock is located somewhere in EFS.

How did you crossflash?
Also i believe when cross flashing a v30 it doesn't touch the efs system either it just bypasses the lock its still there but because of the new firmware it tricks it into working thats what i was under impressions.

If you have a functional LGUP version and DLL for crossflashing V40, please share, this would be a huge help for many folks here.
I have extracted the DLL from the latest LM-V405EBW KDZ but haven't been able to locate a version of LGUP which will successfully flash the device.

Need nvram donors

We need a donor nvram. All you need is files: nvram.bin, nvdata. img, persist. img, nvcfg. img, protect1. img, protect2. img, as well as pc. Goal: We will not take your imei. The most important thing for us is to understand what imei format miui accepts. Thanks.
Background:
NVRAM flew off by my mistake. Here I am with a friend trying to restore the imei. We're close to a solution. But we need donors to finally solve the problem. The loader is blocked
Please tell me I'm off topic. New guy.

Firstly, NOBODY should give anybody NO ONE of these files: nvram.bin, nvdata.img, persist.img, nvcfg.img, protect1.img, protect2.img.
If you have educational purpoises, here is not the place for collecting that.
Well, IMEI is present in NVRAM and NVDATA only.
NVRAM is the permant storage.
NVRAM is never formatted.
NVDATA is the variable storage.
NVDATA is formatted when data is formatted.
Nvdata is mounted at boot:
/dev/block/platform/bootdevice/by-name/nvdata /mnt/vendor/nvdata ext4 rw,seclabel,nosuid,nodev,noatime,discard,noauto_da_alloc,data=ordered 0 0
This is the file containing the IMEI: /mnt/vendor/nvdata/md/NVRAM/NVD_IMEI/LD0B_001

We have been trying to restore the imei for 6 days. We restored the imei only in engineering. Made a backup of nvram. Then we sewed miui. And there we restored the imei, but it gives this error:
So we thought that miui accepts these imeis in a different format.

IMEI for Slot1 will not be accepted on release versions.
Go back to engineering and erase the IMEI for slot1.
It needs to be empty.
Keeps only IMEI for slot2.
And then, it will works perfectly.
Only Xiaomi Centre can recover IMEI for slot1 if you lost it.

The fact is that we used the program sn write tool to restore imei 1 and 2, bt and wf. Then, to remove the first imei, I had to use the Modern Meta program. And with the help of NVRAM editor, we removed imei 1. We launch the phone, we see that there is a second imei. But the SIM cards don't work.

If your SIM card requires the imei it works in slot2 only.

Yes, we know that the SIM card requires an imei. We made imei 2. Then after that we flashed miui (not format all and download) and after flashing miui, imei 2 flew off

But I think it is NOT specific to xiaomi/miui.
NVRAM and NVDATA structures present in MIUI, are same to other brands, models and newer android versions.

If I don't have an imei of 1. Can I link my account to mi unlock if I only have imei 2?

If you wipe data, flash using format all or flash using firmware upgrade, you will lose your imei again.
Read carefully:
1. Erase IMEI for slot1.
2. Write IMEI for slot2.
3. Backup NVDATA.
4. Flash anything you want or wipe your data if you want.
5. Restore NVDATA.
Done.
Keep the backup of NVDATA secure and if you need, just restore it back.

Only IMEI2 (slot2) is enough to bind your mi account and unlock your bootloader

If you want to restore the state of unlocked bootloader, everything you need to do is unlock bootloader first and then backup the SECCFG partition.
If you lock bootloader again, just restore the backup of SECCFG and bootloader will be unlocked again.
