[Q] No Baseband or IMEI After Flash - General Questions and Answers

I flashed my Note 3 (SM-N9005) via Odin with the original firmware (TGY) to reset/wipe it. I wanted to remove everything on it, including the root. After successfully flashing it and wiping it, it seems that there is now no baseband or IMEI. I'm not too sure what's going on, any help would be appreciated.

[Q] Note 10.1 (N8000) cannot upgrade to KitKat, Odin, KIES and OTA fails

Hello everyone
So, I fixed the problem of my tablet being bricked by installing the factory stock 4.0.4 ROM on it, and it has been my go-to resolution for the past couple of days, while I have been struggling to get the upgrade I have been waiting for, for so long.
However, no matter what I seem to do, my device just will not accept the upgrade, and I cannot understand why. Here is what I have done.
Number 1
My android was running a stock 4.1.2 downloaded from Sammobile. I am not sure of the country/region I downloaded at the time, but I think it was either German or from the U.K. I bought my N8000 in China and flashing the firmware to get access to Google stuff was the first thing I did and then upgraded via Sammobile, formerly samfirmware I think. When I saw the 4.4.2 KitKat on Sammobile I downloaded the German upgrade, flashed via Odin like I always had done, and it failed.
I then went on to try via KIES and it did say, that a firmware upgrade was available, however it got stuck and my device bricked. Which led to my 2-day marathon flashing of roms to try and fix it.
Number 2
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then Odin flash the 4.4.2 - Failed in ODIN.
Number 3
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then - Used OTA from settings to upgrade my device. This works until 4.1.2 and then I am told that my device has been modified and that no upgrades are available.
I then try to Odin Flash the Indian 4.4.2 from Sammobile - Failed in Odin
Number 4
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then OTA to 4.1.2. Then I connect to KIES to download the firmware upgrade and it fails and device bricks.
Number 5
Flashed the factory 4.0.1 rom using ODIN 1.83, factory reset + cache wipe and then OTA to 4.1.2. Then I root the device with Framaroot and install triangle away and use the system status modification to trick my tablet into thinking, or realizing, that it is in fact an official.
The OTA upgrade is now available, 800MB downloaded and installation begins, but the process fails and I am left in 4.1.2. I try again, same result. I flash via Odin, it fails, I try Kies it bricks.
Is it just me or is my tablet actively fighting me on this?
Is there anything I can do? Any suggestions? China is not exactly full of Samsung Service Centers, although I am sure a big city like Chongqing has one or two?

No Baseband or IMEI After Odin Flash

So I tried to putting the original firmware (TGY) back onto my phone to reset/wipe it through Odin. I wanted to remove everything on it, including the root. After successfully flashing it and wiping it, it seems that there is now no baseband or IMEI. I'm not too sure what's going on, any help would be appreciated.

Dreaded MDM does not allow factory reset!!!

Wanted to start a new thread on this subject, as I know that there is plenty on it within this site. I have perhaps unique problem with this however. I have a T810 stuck in bootloop and can not get to any UI. I can access recovery and boot loader, but USB debugging is not enabled. I am fairly versed in recovering devices, so I am open to any suggestions.
Where to begin? Suggestions?
Day 2 of this project:
I started with 6.0.1 stock ROM flash as I could not complete a data factory wipe. Stuck in bootloop...
Downgraded to stock 5.1.1... new boot up, but still looping only this time it is cutting off and on.
Then tried changing ROM CSC version from XAR (US) to XAC (Canada) b/c I thought that I had a Canadian version... still looping
I was able to install TWRP 3.1.0 however, thought not sure what I can do with this from here.
Maybe try custom ROM and root from TWRP?

UPDATE: TWRP factory data wipe cleared the issue!!!
Hello everyone, I was given a Samsung Galaxy A5 SM-A500FU, and I have the same problem,
I can not do the hard reset because of the MDM does not allow factoryReset. The phone will restart automatically.
I can not update via Odin because of the MDM.
How do I remove or exceed MDM to reset and update the firmware?
Thank you.

[Help] S9 plus SM-G965F baseband changed to unknown

Hello There Guys
I rooted my device using TWRP, flashed two different modems in the hopes of getting my Imei ng problem fixed, which it didn't. After that i flashed the factory firmware again using odin and selected the nand erase and repartition options (don't really know why). When booted up after the flash , baseband and IMEI went "unknown". I rooted again and restored my efs file yet the IMEI and baseband are still unknown.
Please help me.
Did i somehow hard brick this phone?

I'm not really familiar with those errors on this device but, maybe try to flash stock modem and bootloader? What is your current software version?
Imei status: NG was problem of patch, you should not have messed with modem instead opened a thread about imei status:ng which i could have fixed it online for you via teamviewer or something. Now as it stands you need to flash latest firmware BL, AP, CP, CSC then PM me.
