I have done lots of reading on this and I am still not sure if the solution really exist ...
AT&T Sansung Galaxy S4 i337 MF3 build
1. Having MF3 build, none of the easy unlock solution worked.
2. Can I go back to any previous stock ROM from MF3 such that any of the easy unlock process would work?
3. Will the rooting methods using this be able to sim unlock my device?
4. I assume not, but will updating my MF3 build to any recent ones (MJ6 or MJ9) solve my problem?
Ultimately I want to unlock my device without having to pay $20- $30.
Any help will be appreciated.
Thanks

Lucky you, I just SIM unlocked my friends Galaxy S4 i337 MF3 from AT&T last night so I can tell you your options.
If your phone is off contract (fully paid) you can call AT&T and ask them for an unlock code.
Pay $10-$30 for a factory unlock code for your device from Ebay or whatever.
Root your device, block the AT&T updater from updating you to 4.3, and get the app Region Lock Away from the Play Store.
AT&T denied us the unlock code so we went with the Region Lock Away app from the Play Store and today my friend just activated his AT&T S4 with a T-Mobile prepaid plan. They transferred his number within a couple hours (4 hours or so) and he's been playing with 4G LTE, texting and calling all morning. He hasn't had cell phone internet before because AT&T is so expensive so he is pretty happy.

I did it and it works. My phone is unlocked now. Is it safe to update to 4.3 now ?

Probably not a good idea. The unlock is a software unlock so updating it might remove it and you might lose root capability as well. For now, wait and see if you can still root after the update. If you can, then you can update, root and reinstall the Region Lock Away.
This is the custom verizon version.
Is there any way to get around this or there hasn't been a way to use other sims on this phone?
..
Understand that AT&T has locked bootloader on S5.
Can anyone tell me which model I should buy that will work on the AT&T LTE network but has an unlocked bootloader and can be rooted ? Also understand that there seem to be several variants of S5 available like G900F G906S etc....
Anyone tell me which one to buy ? want to use AT&T but have full control on device.
Thanks
You should but the one from T-mobile it will work with AT&T but you will have to Sim unlock it and you will be able to install roms on it.
I got a Verizon Samsung Galaxy s5 g900v and i plan to start using Net 10 as my service provider but before i do that i want to flash it off from verizon... I hate verizon they won't let us do much of anything and when there is ways around it than it becomes to much trouble... a guy at Boost Mobile said they could flash it to Boost for me but that it would get rid of High speed network.. but he wouldnt do it because he was afaird of getting in trouble.... I wanna flash it to a different more unlocked variant one that i could root that is lollipop and perf one that i can unlock the bootloader for cm12 etc...
Any help would be great! thx in advance..
I got a sprint galaxy s7 edge 935P
Im on tmobile and want full functioning tmobile phone. with working samsung pay so i read I cant trip knox. thats fine i dont care about rooting.
If I flash official tmobile firmware will this transform this to a tmobile phone with all bands working, VoLTE wifi calling, samsung pay no knox tripped?
