IMEI\BaseBand unknown

Hi,
I've got a Nexus 4 Device that has unknown IMEI and BaseBand, hence i can't connect to any mobile network.
the things i've tried to do:
1. Flash to factory image from google (tried several version 4.2/4.4) using ADB fastboot which ran succesful all the way, i just got stuck on the nexus logo when it tries to load ( and yes i tried to delete cache and wipe data before and afterwards, it doesn't work)
2. tried to install different types of radio images on the device regardless of Roms.
3. tried to install various custom roms.
Perhaps it's important to emphasis that, everytime after i tried to install an original google Rom (later than 4.2, my current) it just gets stuck on the nexus logo. BUT, awkwardly, when i install the 4.2 version it does manages to load it succesfully but then again, the IMEI is missing and so does the broadband.
I remember that, originally, this issue occured right after downloading and installing from Google Play store the Root explorer app, when I wasn't actually rooted. I'm not sure exactly how it damaged my deviced that badly, though i find it hard to believe it was the original reason. Rationally thinking, I simply shouldn't be able to access root files in the first place, not lose my IMEI.
*note - I've heard of a HW device called OctoplusBox, that can rewrite the IMEI, though im not sure if even that could help since the baseband is also lost, I may need an expert on this.
i'll do my best to fill in everything i've got right here:
Current version: 4.2.2
Model Number: Nexus 4
Kernel Version: 3.4.0-perf-g7ce11cd android [email protected] #1
Build number: JDQ39
*in the "Status", everything including IMEI/svIMEI/broadband is all unknown.
Thanks in advance,
Let me know if your in a need of any additional information regarding the device.

[Q] Nook MAC Address and B&N registration

Hi,
I installed CWM on my NST, hence I lost the recovery ROM. (should have read the instruction).
I then flashed Tweaked Modded ROM [Feb16] (http://forum.xda-developers.com/showthread.php?t=2651053).
The ROM is great but I got horizontal lines across the screen , and would now like to got back to stock.
I have a spare NST, so I can obtain a ROM.
Can you please indicate what device specific information I need to save, in order to make the stock rom work.
ie. location of MACadress and registration/serial details
Thanks,
H

[q] help!!!! Recovery/rom for d802.

It might seem like a simple topic with a simple answer, and a thread that shouldn't be created, but it's not like that.
The story goes like this. I bought a couple of LG G2's "D802" 32G (ill explain quatation mark later) from Alliexpress for reselling and decided to keep one myself. Being an android fan the first thing I would do is update the firmware or flash a custom ROM. So I tried to install TWRP with no luck, I bricked my phone (trying to get the phone out of the state of "fastboot mode only" resulted in hard brick, after that I sent it for warranty to alliexpress seller). I got a replacement phone, everything as usual, perfect phone from the first sight. Now to my question(s)... :
1. I checked the IMEI on Swappa, it doesn't even show what phone model it is. I tried to enter the IMEI to this site: http://csmg.lgmobile.com:9002/svc/popup/model_check.jsp?esn=xxxxxxxxxxxxxx for .img extractions it won't load as such IMEI seems to be not real!!!
2. After reading around I found this thread: http://androidforums.com/threads/in...-international-hong-kong-version-32gb.877957/ . It says here that IMEI counterfeiting is not a new thing and changing one model to appear as another (for example D800 to D802) is just a matter of flashing a modified image, thus resulting in wrong IMEI numbers.
3. Now the main question: How do I safely install a custom ROM for my particular model (ill check what model number is printed under the back when I get home)? Would flashing a recovery requires reflashing the phone to it's original state trough download mode , let's say to D800 partitions? Would model check when flashing wrong files prevent me from installing anything at all?
If someone knows how to deal with this, or maybe even had simillar experience could help me, that would be amazing. Thank you for taking your time to read and reply.

Two identical phones, one broken the other is stock [Note 4 910H ]

Hi, I have a problem with one of my phones. The one phone that isn't working the way it should goes as following
Rom : The TeamEos Project [5-20151015-NIGHTLY-treltexx]
Baseband : TEST1
Kernel : 3.10-g9c9bafa [[email protected] #1] (some TeamEos kernel that followed the rom )
Buildnumber : eos_treltexx-userdebug 5.1.1 LVY48F 36d89b5523 test-keys
And the device model is actually SM-N910H but it says SN_N910C
The phone doesn't always do what it's suppose, like camera, mic, connecting to wifi.
Also when i start the phone on the top left corner it says: KERNEL IS NOT SEANDROID ENFORCING
I do however have a phone that i stock and never touched.
Is there anything i can do to restore this phone to stock or stable?

Found a fix. Put my phone in Download mode and used Samsung kies to restore it
Kies fixed it. Even had a problem where when the phone turned on it would display random colors in lines or whatever was on the phone before it shut down. Kies fixed that too.

SM-T530NU Spontaneous Rebooting

Hello fellow XDA'ers.
I'm looking for some help in resurrecting a tablet I recently bought off of someone..
The issue with the tablet plays on multiple ROMS.
With the stock Samsung OS, the tablet gets past the boot-loader, hits the first few frames of the boot animation and freezes, Reboots and repeats the process.
With the same firmware and Lineage OS, the tablet does the same thing but not as quickly.
The neat thing is that if we leave the tablet to rest for a few hours, the farther the boot process advances.
We've gotten into both OS' setup screens, but lineage was able to get to the part of telling us that theres a missing SIM card.
Which this tablet does not contain a sim card reader...
Could I possibly have the incorrect Firmware image on the tablet or a bad motherboard?
The device has been verified as a SM-T530NU via serial sticker located on the back.
Model Number : SM-T530NZWAXAC
Model Name: SM-T530NU
I used this firmware to bring it back to stock
I would love to receive some help in terms of pulling logs (Samsung Hardware Logs - Not dmesg)
and finding the culprit to this non-booting Tablet. I will compensate for the work as well
Here's a paste bin of dmesg if that might help

Do you by any chance know if you have connectivity issues with wifi or BT?
See my thread as I have been working through this issue and let me know what we maybe can hash through together.
