No baseband IMEI after flashing 5.0 - ONE Q&A, Help & Troubleshooting

The issue I have been having is that the phone reports unknown baseband version and there is no IMEI. Wifi was still working originally. The issues came after I flashed the latest lollipop alpha modem needed for the latest CM12 build/kernel.
After I experienced the issue, I flashed back the 44s modem. Then Wifi was also gone.
As of right now, the best I can do is:
1. Install ColorOS 2.0.0
2. OTA to ColorOS 2.0.4
ColorOS gave me Wifi back.
At this point, I tried to fastboot install TWRP per @NikoZBK suggested. The fastboot command reported successful but it still got the ColorOS recovery. So I have to...
3. Fastboot flash 30o with flash-all.bat
However, by doing so, my Wifi is gone and I still have unknown baseband version and IMEI. Therefore, I went back to (1) and (2), took out this line: fastboot flash modem NON-HLOS.bin in flash-all.bat and run flash-all.bat again.
At this point, Wifi is still working but I still have unknown baseband version and IMEI.
4. Flash pre-rooted 44s in TWRP. The issues are still there.
I also tried doing "make_ext4fs /dev/block/mmcblk0p15" in TWRP and it actually killed Wifi. I am running out of ideas. Any advice is appreciated. Thanks!

Signal dropping several times after KitKat update

As you can see here: https://forums.motorola.com/posts/48fb0b8150
And here: https://forums.motorola.com/posts/c23d71e3d8
Guys, I'm getting desperate with this situation...
After upgrading my phone to Android 4.4, the carrier signal repeatedly drops 2 or 3 times on every 15 minutes! Even when I'm in a call! Sometimes the No Sim Card icon appears as well.
Before Kitkat, everything was ok.
> Tried to revert back to Stock 4.3 ROM, but I did not succeed, the problem persists.
> I installed the correct modem file (NON-HLOS.bin) several times and no solution.
> Motorola only guides me to change the SIM Card, make a factory reset or consult the provider.
> But I've switched to SIMs from multiple carriers and the same thing happens.
> The problem seems also to not be linked with the carrier signal because I live and work in different cities and the signal keeps dropping here and there.
So, I reached in a point where I do not know more what I can do.
Does anyone have a light for me? Someone also had this problem?
Outline the flashing history of the device from when you bought it. What do you mean when you say reverting back to 4.3 ROM did not succeed? Did the flash fail?

No, the flashing process was fine.
I'm on Stock 4.3 ROM right now, but signal keeps dropping.
What fastboot commands have you used? Did you include:
flash modem NON-HLOS.bin
erase modemst1
erase modemst2
flash fsg fsg.mbn​

Yes, exactly it. I also used a flashable 4.3 Modem zip by @dhacker29 , no solution on two ways
What model do you have? What is your stock firmware? It sounds like you are not properly flashing the stock firmware. Please post the list of commands you are using.
lots of problems in the uk with signal dropping after upgrading too kitkat but if you have flashed it back too 4,3 it cant be the same issue,i have flashed back too 4.3 and everything is fine again.
https://forums.motorola.com/posts/48fb0b8150?page=1 ,thats the problem page on motorola forum for the issue.
Kit Kat made changes to the APN and not all carriers updated the APN file in a timely manor. Suggest you check what you have and make sure it agrees with The carriers latest info.

I have a XT1033 (dual sim variant).
My stock firmware is 'fastboot_falcon_retbr_ds_user_4.3_14.10.0Q3.X-76-LCG-9_61_release-keys-cid12-Brasil_BR.tar.gz'.
As you raised suspicions about firmware mismatch, I have to say:
> I bought the device with 4.3 from factory.
> Unlocked bootloader.
> I installed 4.3 from UK (only one SIM worked, ok, I was excited to taste kitkat).
> I updated to 4.4 via OTA (here the signal problem appeared).
> I installed root.
> Out of curiosity I spent a day with the CM11.
> I went back to 4.4 via backup.
> I installed the 4.3 from Brazil.
> Reinstalled 'NON-HLOS.bin' from my ROM again.
> I installed the 'NON-HLOS.bin' from @dhacker29.
> I went back to 'NON-HLOS.bin' from my ROM again (here I am now).
Did you run the flashall.bat included with that firmware?

Yep, two ways, flashall.bat and manual commands as well.
There is another stock firmware image you could try.
fastboot_falcon_retbr_user_4.3_14.10.0Q3.X-76-LCG-8_41_release-keys-cid12-Brasil_BR.tar.gz​

No signals on my XT1033 pls help

Dear friends
I am facing a serious issue with moto g xt1033 indian version. I explained what I did. It is my friend's phone.
The phone is updated to Lollipop 5.0.2 through OTA. (Not through flashing OTA zip)
I unlocked bootloader, and flashed twrp recovery 2.8.6
Then flashed cm12.1 20150515 nightly and super su 2.46. Everything went fine and the mobile booted in to cm12.
But there is no signal in both of the sims.
So I searched in google a lot and find the below thread
http://forum.xda-developers.com/moto-g/general/guide-cm12-moto-g-t2952031
I saw the below at first step of the thread
Do not flash CM12 if you flashed lollipop OTA.. It will hard brick your mobile
But the mobile is didnt flashed OTA zip. it is normally updated through OTA
If it is the reason then give me a solution to recover the phone
And I did install the GPE 4.4.2 as mentioned at option 1
But it get struck at boot logo.
After that I flashed stock 5.0.2 Asian retail firmware through fastboot. Every thing went fine. But again it stuck at boot logo.
If I flashed cm12 or any stock zip files It get boot but no signal.
I searched a lot and cant find the solution.
Please give me a solution to recover my phone.
Still I can access fastboot
Check if your IMEI number is still present. Does WiFi work?

No radio or service what so ever....

Hello everyone. So here's my problem, i was flashing the android marshmallow rom that was just ported over to our lovely phone. I got it to work, it booted, ran smooth the only problem was i had no service at all. i still have my baseloader and imei but my service state says radio off. i did do a backup of my efs before i flashed marshmallow but it didnt work. i just reflashed it to Oxygen os and it still says radio off. ive tired flashing modems but i dont exactly know which one to flash. ive tried flashing other roms but to no avail. i really need my phone so any help would be greatly appreciated
Did you try moving to older versions of the OS.
Try doing following
1. Install any Android 5.1.1 firmware. This should restore the Radio
2. Install any suitable radio/modem explicitly
Let us know if it helps. Best of luck dude

I have to fresh install the ROM on my OPO because I got it bricked so I followed this guide now my radio still doesn't work and the phone is constantly rebooting. The issues came out just like @agentxur did
Considering that you still have your baseband and IMEI (You're Lucky ), you can just flash 44S Modem via Fastboot or full CM12.1 Firmware. I will leave out a link for 44S Modem down.
44S Modem: https://www.androidfilehost.com/?fid=95784891001607675
PS: Flash it through FASTBOOT only!!! Else won't work
I hope the method pointed out by Sanjiv Kumar helped you. Whatever your feedback let the members know.

I just recently installed Linux on my laptop so I don't have fastboot right now but I actually read somewhere that twrp 2.8.7.0 (which I was using with multirom) won't flash modems or radios correctly so I reflashed 2.8.6.0 with rasher app and it worked. Thanks tho

XT1031 failed to flash stock 5.1

I first restore to stock 4.4.4 from CM11 by manually flashing falcon_boost_user_4.4.4_KXB21.14-L1.57_57_release-keys-cid9.xml.zip. Everything worked.
After that, I try to upgrade to stock 5.1 by manually flashing XT1031_FALCON_BOOST_5.1_LPB23.13-56_cid9_CFC.xml.zip with mfastboot. Every part seemed to flashed successfully, but when it is finished, it won't boot and stuck at bootloader unlocked screen.
Now I cannot downgrade to 4.4.4 since the gpt.bin and motoboot.bin all failed preflash verification. I guess the bootloader won't allow downgrade. Even with all other parts successfully flashed, it is still stuck at booloader unlocked screen.
I also tried to flash twrp 2.8.7.0, but it also failed due to partition size different. (Is it because twrp can only be flashed under 4.4.4 bootloader?)
So I am stuck now. Please help me. How do I flash stock 5.1 and later CM12.1? Thanks in advance.
Try flashing the firmware with RSD Lite and see what happens.
Sent from my XT1031
Fixed. I found a stock rom 4.4.4 downgrade package from here.
https://www.reddit.com/r/MotoG/comments/3omnox/moto_g_xt1031_boost_lollipop_stock_rom/
It has same contents as the 4.4.4 stock rom package I downloaded from filefactory, except there is a fastboot.exe boundled in this package (dated 6/25/2014) that is newer than the one I was using (dated 3/20/2013). This one successfully restored my XT1031 to 4.4.4 stock.
Flashed of twrp and also flashed stock 5.1 optimized from twrp. Both went well.

[Help] Accidentally set radio to USA band(XT1033)

I was fiddling with the testing menu on XT1033(GCC Model) running Official CM14.1 Nightly dated 12th Nov 2016. I changed the Radio to "USA" as it was the only option. Now I have no data and no network to place calls.It doesn't seem to detect the sim itself. I am not able to change the radio band now.I tried clean flashing the rom again but still no luck.
Is there anything I can do? I have a complete nandroid backup from MM roms. Will flashing any of those help? Or should I unlock all bands for this device by following this guide: http://forum.xda-developers.com/showpost.php?p=55475431&postcount=1
Or should I revert back to stock?
have u tried to flash respective radio/kernel from here??

Flash the radio file from this link http://forum.xda-developers.com/showthread.php?t=2649763 this solved the problem for me. I flashed xt1033 5.1 radio twrp flashable zip file. hope it works for u too
Thank you guys but I didn't have to do any of the things you guys mentioned. I simply clean flashed AOSP 7.0 and then I deleted the radio firmware cache with the following commands in fastboot mode:
fastboot erase modemst1
fastboot erase modemst2
When I rebooted my phone,it worked.
