If you updated by keeping the MF9 bootloader you can go back to stock. If you took the OTA however, you can only downgrade to 4.2 with a custom ROM.

i tried eveything so i can downgrade and how he said is the only way. i been trying everything but no luck. i hope your not trying to return your phone because if u have it rooted and have "kernel not seandroid enforcing " then wait until some dev can fix that

but i can downgrade to 4.2 (100% 4.2) using a custom rom?? or i will be on 4.2 but with the same new bootloader?

what custom rom would work in my case? if you can give me a link to one.. there are so many here.

If you're on the MJA or MK2 bootloader, you're stuck with it.

And why would you want to go back to 4.2? Any ROM would work, but seems kind of pointless.

I believe you just need to downgrade the modem. Not sure tho.

i downgraded the modem to mdc and did the unlock process. it worked, i can make and receive calls but when the phone is going to 3g i get a error message "LTE esm 29 emm-x cannot establish wireless data connection" nobody else had that issue.. i dont know if hte fact that my phone is not activated on spring is relevant.. it shouldn't be, because im using the phone outside the US.

i dont know what to do to make this thing work.. i have flashed from mdc to mk2 or mja like 5 times and i always get the same message.
