(SOLVED)Lost IMEI/empty efs folder topic

I had some major issues after flashing a new rom with latest version of philz advanced recovery...I lost my efs data and all data connectivity... After doing some reading I saw posts saying that flashing stock in Odin would fix my problem quickly and easily...went through that whole process and it fixed my connection...I was then stuck in factory mode and did more reading...according to everything I read I could fix this easily with a file edit...it stated That all I needed to do was navigate with a root explorer app to efs/FactoryApp/factory mode and change off to on...and then to efs/FactoryApp/keystr and also change off to on...easy right...wrong...my efs folder was completely empty...I searched and searched for an answer to my problems for 2 weeks...no luck...I came across many people with jflte and same issue...none ever found successful fix or just never posted it...I did try backing up my efs when I first rooted...but the app I used backed up mmcblk0p3...our efs is located at mmcblk0p10...so my backup was actually for sbl1...awesome...after countless hours of tinkering and reading I came across an old post from a gs2 forum and it did lead me to believe that my efs partition had been formatted to the wrong format to be mountable...after trying every tool I could find to reformat it to ext4...I gave up...I called a Samsung service center and was sending it in to be fixed...they said it would be updated when I got it back...I'm on mdk and was heartbroken to hear this...got a case of the f its and started tinkering more...went back to gs2 thread and someone has posted about an app on play store called gs2_repair...it works...it mounts the partition correctly in ext4 and from there I had to fix permissions or it would unmount on reboot...just following the 2 file edits I talked about previously got me out of factory mode and I was good to go...hope this helps somebody else!
