Did your phone have the 4.3 bootloader before downgrading to 4.1.1? It was my understanding that you cannot downgrade the 4.3 bootloader.

Boot into download mode. If you see something about warranty bit, you had the 4.3 bootloader.Something tells me I didn't have the 4.3 bootloader if you're all asking about it. How do I tell?
If I have already done the free unlock in the past and since upgraded to 4.3, but now I want to downgrade because 4.3 is terrible, will I lose the unlock that I already applied?

Do you have the stock 4.3 bootloader on your phone? If you do, you cannot roll back to an earlier ROM as 4.1.1 and 4.1.2 modems don't work on the 4.3 bootloader.
I tried this tut and it didn't work and made no sence any way some on could make a video on downgrading
Yes I flashed stock 4.1.1 from samfirmware following instructions exactly....I successfully get to 4.1.1 BUT with NO IMEI on my phone and no way to restore it with EFS pro.....it claims the restore works but it never does...
I had to flash 4.3 from samfirmware back to my phone and my imei came back thankfully! Than I had to get it out of factory mode back into user mode...what a mess....I do not reccommend anyone try this unless you find another way besides EFS pro to backup your info and restore it on 4.1.1 because that program sure did not even tho it said success over and over.....reboots - battery pulls nothing helped!
Strange thing , no matter how many times i flash 4.3 with odin I never get knox back...where did it go that it cannot show up anymore? lol
You need the NON-HLOS.bin from stockrom 4.3 to have imei and network because the bootloader is 4.3, I explain that in the first post, just flash the NON-HLOS.bin from 4.3.
After flashing from 4.3 to 4.1.1 were you able to unlock the phone without having IMEI number?
Yes, I just used Odin (not Kies) and flashed the 4.1.1 image I had and once it rebooted, it came back up. Only thing I did before hand was format /data /system /cache and the dalvik and I had no issues. Only thing I can say was I was runnin CM and not OEM images.
I have unlocked three phones (all of them were i747m ) using the free method but none of them had been upgraded to 4.3 so we'll have to wait for someone to try using the free unlock method on a phone that is running a 4.1.1 ROM with a 4.3 bootloader.
