What do you mean exactly? You can`t use EFS data that is not compatible/assigned to the motherboard of your phone, ie someone elses EFS data.
I was asking if the tool that they have in the OnePlus 3 Forum could be used to backup EFS would work. But I see that it can't because I tried it.

If you have TWRP you can backup your EFS file in recovery and store it on the PC .

I see that but it was hinted in the OP3 forums that the twrp method was unreliable?

Or try this with adb:
You must be rooted.
Open an ADB shell or install a terminal emulator like this one https://play.google.com/store/apps/d...roidterm&hl=en
After that, write the following 3 commands:

su (press Return)
dd if=/dev/block/mmcblk0p10 of=/sdcard/modemst1.bin bs=512 (press Return)
dd if=/dev/block/mmcblk0p11 of=/sdcard/modemst2.bin bs=512 (press Return)

Backup files modemst1.bin and modemst2.bin will be created on the root your internal storage.

To restore them flash them both seperately without rebooting in fastboot.

That doesn't work. Actually, I ran this through adb and also got similar results.
