I have network problems with my phone, I have done a lot of researches and those issues may be a result of corrupt efs, I didn't do a backup so what I wanted to do is that someone share a full efs backup, I know that it contains the imei so it will be illegal but I saw that we can remove that number from a qcn backup (made with qpst) with efs professional.
What Im trying to do may help a lot of users who have the same problem as me that didn't do an efs backup, but the problem is that I don't know if it will work and if the efs backup contain more info that will make it illegal to share.
I have been like 3 months now trying to fix my phone but I can't, it has signal problems, before I flash the qcn from here that enables aws bands I had no signal at all but after I flashed it I have some signal but in some places, i think that may be that only some bands are enabled, the aws bands, I think that I screwed the efs folder because when I bought the phone the signal was incredible where I live, I had the 5 signal bars and know only 3, 2,1 and zero signal, my info of the phone is fine, I have the correct one number just the serial number is 00000000000, I restored the imei with qpst but can't do the same with the s/n.
Well I hope that you or something else can help me with my problem and think about the efs backup that I was looking for I'm not an expert but I think it could work, thanks in advance and sorry about my English since is not my native language.
If I'm asking for something illegal just erase the post.
