I originally rooted 4.3 & was working great. When 4.4 update came out, I re loaded stock 4.3 & then OTA update. Long story short, want to go back to rooted 4.3 so I re loaded stock 4.3 & now S3 has no IMEI & SIM is not recognizable. Tried other ROM but get errors installing. I'm really hurting here so any help will be greatly appreciated. This is what my phone looks like - (1 pic is in Development Mode).

Looks like you need to reflash the ne4 modem, since the ota gave you ne4 bootloader and downgrading to 4.3 rom probably trashed the modem...

Quick question - The link here says a warning about not flashing ne4 on 4.3 firmware, just want to know if this is correct because I'm on 4.3 JB? Also, could I just load a modded 4.4.4 ( http://forum.xda-developers.com/show....php?t=2728553 ) on before I flash the n4 or after I flash the n4?

Thanks

Yes it is correct. Several bricks have already occurred due to ending up with the 4.4.2 modem on 4.3 firmware. Looks like the rom you are using is 4.3, but this may not also be your base firmware build. Install and open terminal emulator and enter this:

getprop ro.bootloader

It will tell you what firmware you have. If it is not NE4, do not flash that modem. Instead flash whatever modem matches the version the above command said you have. So if it said you have MJB firmware, flash the MJB modem.
If that doesn't help, the next thing to try is flashing the full 4.3 firmware package via Odin and factory reset. (Make sure you backup everything prior to this! Including your internal sd).

Note: if getprop ro.bootloader says you are on NE4 firmware, do not try to flash the 4.3 firmware over it. If already on NE4, then flash the modem linked previously.

Terminal showed I747UCUFNE4 so I went ahead & flashed the NE4 & it worked! My phone still looks like this (pic) Can I flash a custom 4.4 now that the modem is fixed?

Glad I could help! In case that box with yellow text comes back up, this is what to do. (Its called Factory Mode btw)

Open Terminal Emulator and enter this:

su
echo -n ON > /EFS/FactoryApp/factorymode

Thats it! Glad you got everything sorted out!

You saved my phone! A whole week trying TONS of things and I just found your post by chance and that was the problem.
Thanks a million.
