[Q] Can someone help me understand what I did wrong (already fixed but want to know)?

I received a replacement phone from AT&T and it had the latest firmware (I747UCDMG2) on it. I did not know this till after I rooted my phone. After rooting my phone, I installed TWRP and then went to install Task650's custom ROM. I got some errors there where it looked like it listed different baseband versions. I exited it out and tried booting up - I could no longer boot into my phone. No matter what I did the phone would say recovery booting but shut off immediately. After removing my battery and leaving it out for a few minutes, I was able to boot back into download mode. I ended up falling back to LK3 stock ROM. Finally my phone was back up. And now installing Task650
Now was I not supposed to use Task650's custom ROM on MG2? Or was it just a fluke thing?

Did you update the bootloader before flashing the ROM?

I never have so going to say no. Or maybe I have and I just don't remember. I'll look into it but I definitely didn't update the bootloader

[Q] Help on reverting my I747 back from a T999 convert?

So, a while back, i decided to convert my ATT galaxy s3 to a tmobile build so i could run LTE from tmobile on it. Now, my problem is, i want to revert back to full att again, in which i have tried, but im getting something wrong (Status 7 errors and what not, i feel related to the changeover) and i don't want to brick my phone trying over and over. I could use some help with what ill need to FULLY get back to at least stock so i can root and install a fresh kitkat rom. Any help is appreciated!
I attached a screen of my build as well.

How exactly did you go about this? What were the zips you used to do this? What zips are you trying to flash? These are all things that can help us out in figuring out what went wrong.

Well i had read around of a test rom created especially for tmobiles GS3 variant that ran on att in order to run their LTE. So i flashed that rom and i believe custom kernels and a modem. Only thing is i cant backtrack what i did and the original files i used are lost.

Anybody? Hehe I really need to get to a computer soon ..

That's an easy fix.
Odin back to a stock 4.1.x, rooted or unrooted.
Then on first boot hold volume up + home button and to a factory reset. Done.
PS: make sure you're not running 4.3 OTA latest bootloader or you will get a semi reversible brick.

Ok awesome! Ill look up the odin stock guide on here....but you daid it jad tp be 4.1.x right? And what about updating it later on?

Also, as another option, what would I be able to flash it to to keep it in its current tmobile state but updated to a shiny new rom.

Your cwm is out of date.
Update your recovery at that error will go away when flashing

what good is a backup

what good is a back up of any kind if i cant ever get this phone re reboot back into recovery once i am in a bootloop.
buttons dont work, adb dont see the phone and the backup gets erased when i restore with a tot. so what good is a backup.
MOD EDIT: Removed foul language. Let's keep the language clean.

What are you doing to put your self into a boot loop?
Have you tried up and power... Using factory reset which will throw you into recovery.

i dont know what to do from here but i am going to take a break before i throw this thing at the wall for real.

Welcome to the LS980 struggle. ZVA and ZVC radios break Loki. You need to downgrade your aboot to get things working. My personal recommendation? If you don't have Spark in your area, tot back to ZV8 to use AOSP. Just read up in the dev section for all the caveats.

I'm assuming you have upgraded to some other model kitkat rom and want to revert back to sprint rom. I had the same problem yesterday it turns out knox on those kitkat roms forbids you from going back to lower version rom. What I did was to odin ne2 rom and it went smoothly.
