AFTER UPDATING TO KIT KAT MY PHONE LOST SIGNAL

HOW TO FIX
________________

You will need to downgrade your modem firmware
I've have included the MJ4 modem firmware in the download link
simple flash with odin

HOW TO FIX AFTER RESET
------------------------------
If you did like me and reset your phone trying to get signal
before you downgrade the modem make sure your phone is flash
you will not have signal yet so double check your work
then ODIN down to MJ4 modem

HOW TO FIX NO DATA CONNECTION & HFA
--------------------------------
Your phone must be rooted
Use root explorer extract files from note3 carrier.zip
and copy and paste all in carrier folder
reset phone and run profile update

I need help. I have a phone with a red x on it and i would love to get this working. The link says that nothing is there.
I have this file too. I posted it in the development section. if you have an invalid Md5 error, remove the .md5 extention because usually, the file was renamed after and changed the checksum. Not safe to do, because there's no verification, but it works

I've had this problem for a while.
After MJ4, no radio seem to work for boost.
The only idea that makes sense to me is the NV items.

I'm no expert, just throwing out an idea.

is there anyway to just flash a rom and not update the modem?
a "dirty" flash will do it, but it may come with rom issues.
worse case, just Odin the baseband tar.

what rom did you dirty install? I installed bonsai 1.0 over .5 and it just stayed at the note3 screen. Did you have in upgrade the recovery first, or anything like that? ThaNKS.

Most of the time when your rom wont boot, its a kernel issue.
I dirty flashed Freeza's NH7 rom.

I'm inclined to believe our problems stem from "wifi calling".
It was introduced in NC5 if im not mistaken, & thats when boost Note 3's started to have problems.

I've found an interesting anomaly with the modem issue.
after the MJ baseband, all the newer modems flash APNHLOS to our phones.
not sure just yet what it does, or how its attached to the MEID, but that's my find.

Any ideas?

n900p red x no signal fix

n900p red x no signal fix
got it fixed, even though supersu disabled knox, there was still a security issue. I used titanium backup and searched for knox. then I disabled everything that had to do with knox, instantantly t-mobile pop up.
