Hi everyone! Thanks in advance for your wisdom...

So I was given a LDU of the note 3 by my brother who works in a Samsung retailer. Unit works great, was able to root and disable the retail mode and keep it from wiping the phone every night. So far so good.

One thing thats interesting is that GPS is installed and working properly and is able to locate me and ever navigate, which is interesting as I've heard that these units lack both GPS and radio.

The phone is also able to take a chip and when I put it in, of course, the phone doesnt get any signal BUT it does rexognize a chip is in and shows me the little SIM app that I can go to check some carrier stuff (which I cant check as I get an error everytime I click on an option).

IMEI shows as unknown BUT APN configuration is lifted straight from the chip and appears automatically in the phone.

Is this normal or am I missing something here? When I check "about phone" the model shows as N9005 is that normal too? Ive seem to understand that it should show n900x?

All of this makes me wonder if theres some light at the end of the tunnel and this phone could be used as a proper GSM phone. Can you share some of your wisdom?

I've toyed around with the idea of getting a note 3 motherboard and swap it so I can eventually fully use this phone, but before I wanted to check if what I mentioned is normal for a LDU or of theres a way of making sure this phone does actually have radio installed.

Thanks guys.

Ok upon further inspection the device does show sm-n900x on the sticker behind the battery. Still, should it have the GPS working? Any chance it could actually have the radio HW?

It doesnt have imei so aim card will not work. There is a thread here that says you can "recover" imei. Search the EFS threads and if you find the link, try it and let us know if your phones works. Good luck

Can you show all info from your phone?

Hi

I have the same live demo unit. I opened it and found there is no antenna in it. I researched on the same issue a lot and found some users got signal after installing the antenna. Most of them(including me) are facing the problem with null imei.

Key Points during my reserach
1. Missing Antenna.
2. Its a LTE model and also found sm-n9005 on the motherboard when I opened it.
3. N9005 ROMS should work.
4. Found that its trying to read SIM card but it unable to and its detecting for sure.

My doubts :
1. If any hardware is missing it may go into bootloop if any stock ROM is installed so should know if the complete hardware is there or not.
2. How to fix null IMEI ?

I am just the beginner. Just posted this as it may bring new ideas :) please dont experiment.
I am stuck at fixing null IMEI. Once its done I will try burning stock ROM. Before that please help me in fixing null IMEI. So that I will experiment and let you know the feedback :) so that you can experiment :)

How do you have the IMEI if you don't have radio hardware?

Check your modem board info using Phone INFO ★Samsung★ app.

Hi Sir,

I checked my modem board and its showing MSM8974. Is it a valid one ?

Also the screenshots which previously posted by theprint are matching with my phone. Wen it is having IMEI I think I can also have the IMEI by some means. Correct me if I am wrong

Can you show ALL screenshots from the app Phone INFO ★Samsung★ ??
I will do more investigation and tell you later.
And also take a picture of the back sticker (behind the battery) and send (or PM) me.
