is backing up of EFS partition the same as backing up QFS - Xiaomi Redmi Note 3 Questions & Answers

i saw that we should backup EFS when flashing , but i also read that some people backup QFS so as not to lose IMEI, should i do both? or should i simply backup the EFS partition , any advice please

hold efs partition backup should be enough, if you keep both also fine. personally i keep efs backup only and never use it due to when i lost my imei, i only need to flash some modem files

flashing modem files fixes your IMEI issues?

Nitrality backup location

What is the Nitrality backup location?
I know where it is now but i do not see efs backup there
does it mean so it does not do efs backup?
OK now i know ti all but also kno that it does not do a backup of EFS partition just a files. The question is if there is a program that makes full backup of EFS partition and can recreate it when it is corupted?

[Q] EFS Backup

Hi all,
need to ask a couple of questions regarding the EFS backup.
1) If i use the kTool for EFS backup and do a total wipe before flashing custom ROM, (mounts and storage>format system) will the EFS backup also get wiped out? My common sense tells me yes since the internal SD will be wiped out and kTool saves the EFS files on the internal SD but just want to be sure so that i can search an alternative method for backing up as i want to flash custom ROM with total wipe.
2) Does the EFS Pro app save the EFS backup on the internal SD only or does it have an option to save on ext SD card?
3) Do i just have to be rooted to backup my EFS files? Im just asking as im terribly obsessed my EFS files will get corrupt while rooting the phone! Is there a simple way to backup my EFS files on my ext SD card without root?
4) Can my EFS files really get corrupt just by rooting my phone?
Thanks in advance for any feedback

I know nothing about EFS backup but how about this. I assume you have access to a PC and the usb cable that came with the fone. Or else you do have a microsd card in the fone. Why don't you do the backup and copy the files to either the microsd card or a PC. That way you know you have a backup you can use.
In most cases, and someone can correct me if I'm wrong, the format system will not touch your backups.

Yes very true, i can also do that and it also crossed my mind but im afraid that by doing so, copying the EFS files and folders onto a PC or directly to the ext SD card will alter the files and folders in a way that they cannot be restored and i dont want to take that risk unless im totally sure of what im doing or if this can actually be done.
Thanks just the same for ur feedback
Ok so I just found out that with EFS Pro I can backup on my pc safely. Do I need to be rooted to use this app and safely backup the efs files?
Thanks

corrupted efs

Hey guys. My efs is corrupted after I tried to restore the whole system from twrp from my external sd card. I canĀ“t do anything with my phone (no format,no wipe...etc.)
Could anybody with a SM-G950f create a backup of the efs section with twrp and send it to me? This question may sound weird, but I really think that could help me to restore my corrupted/deleted efs folder..
Thank you so much
