Restoring baseband / modem - General Questions and Answers

After installing LOS 17.1 I had no cell network (wifi worked).
I found a tip here that recommended to use
fastboot erase modemst1
fastboot erase modemst2
But that made things worse. I not only have no network, now the IMEI is gone, phone number not detected.
I tried now to flash modem from stock rom:
fastboot flash modem NON-HLOS.bin
but this didnt help either....

[Q] Imei Issues - In desperate need of rescue session, have EFS backup

Hi fellas,
my opo gave out after I switched to an f2fs filesystem and flashed AK kernel, both lollipop... I know dum.
but I ran into the problem where it doesnt recognize my sim card anymore so I checked whether I still had an IMEI and it shows nothing, neither does baseband.
funny enough wifi and bluetooth seem to work, I have backups of modemst1 and modemst2 but flashing them doesnt seem to work, I tried the nightmare fix already and i'm feeling pretty lost now.
Please can anyone help me out?
Same issue here
I'm able to use WiFi properly, however, there is no sim detected and no IMEI either.
I have multiple EFS backups on TWRP as well as the modemst1 and modemst2 files.
Even after restoring the EFS backups, it doesn't help.
Try finding system image and flash it via fastboot
Or tool.
But it will lose all data so be careful and try backing up on your pc.
Sometimes just flashing original system image can bring them back. But don't mess up too much wid it. Bcz i have dead note 2 bcz of that.
So try to flash system image full may ne it will help.

Follow this guide
http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061
If you have backups of modemst1 and modemst2
Code:
fastboot erase modemst1
fastboot erase modemst2
then
Code:
fastboot flash modemst1 modemst1.bin
fastboot flash modemst2 modemst2.bin
Otherwise you can erase those two partitions then use this if you don't have backups
Code:
fastboot flash modem NON-HLOS.bin
this file (NON-HLOS.bin) is usually found in any CM based ROM by unzipping. These instructions are in the guide I linked so read through that too and attempt the solutions there before attempting these commands, they are meant as a last resort if the others don't work

No Wifi (Mac address 02:00:00:00:00:00) and no sim card with Moto G LTE 8gb (xt1039)

Hi I wanted to install CM on a friends phone. He wanted to buy a Moto G 2013 (falcon) but he did accidentally buy a Moto G LTE (peregrine). I just noticed that because I tried to flash recovery for falcon and it did not work at all. Then I opened the phone and discovered the sim card slot
Now I upgraded Bootloader to 411A and installed TWRP v2.7.1.0 and tried to flash CM 13. CM boots up, but it doesn't recognize sim or wifi Wifi-Mac is shown as 02:00:00:00:00:00 and baseband version is unknown. and model is shown as xt1039. Any suggestions? Tried all available CM nightly build (older ones are 404 for peregrine) and also the crdriod rom. Same problem with every rom. Full wipe of data and factory reset done
You have not updated the radio firmware. This is done via fastboot: (files are available here)
mfastboot flash modem NON-HLOS.bin
mfastboot erase modemst1
mfastboot erase modemst2
mfastboot flash fsg fsg.mbn​
Thanks

Hi, even I've Moto E 1st Gen with CM 13 installed in it and having exactly the same issue with WiFi not working and MAC address showing as 02:00:00:00:00:00. Even I am not able to make or receive calls in my Moto E. I'd be really thankful if you mention the steps that you did to solve the problem.

Umm... why would you erase the modem firmware???
You need to get the correct firmware image that matches your boot loader and perform:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
To be honest, your device is in an "unknown state" at this point, I would do a factory reset in the ROM (in Android, not TWRP), then flash the full factory image, boot fully, and make sure everything is working before continuing.

I've found this room, but i'm not sure if my cellphone is LPI23.72-16.4 or LPI23.72.43.
I should flash this room just like i've flashed CM ?

Never change mobile data option to SIM2 !!!
I'm in the same situation with Moto G 3rd gen XT1543 with Andoird 6.0:
I'm using two UK sim's: Three (Sim1) and EE (Sim2).
When I changed the mobile data to Sim2.... THE HELL !!! Sim1 appears in the list but signal is not available anymore.
I tried to switch both ones, and nothing.
I tried the Sim1 in another phone and it works perfectly!
When I take Sim2 off, Sim1 came back to life but just with voice, no data! Plus when I tried to switch mobile data to Sim1 (remember that I take Sim2 off at this moment), it do not ignites mobile for Sim1 anymore.
Conclusion: NEVER switch the mobile data to SIM2 !! Is a black role in the Motorola week software.
I tried everything you could imagine: turn off, enable and disable all possible combinations between sms, mobile data and voice options between both Sim's and nothing !!! Sheet Motorola !!!

xt1955-5 Can't get LTE

Okay, so the phone was my wife's, had LTE with stock firmware.
Got her a new phone so I took this one and did full flash from fastboot using the latest retail image (used lenovo restore app).
Flashed lastest Lineage OS image. Can't get anything other than 3G.
Flashed latest stock image both with Lenovo, AND manually via fastboot.
Still no LTE. (sim has LTE on my moto x4 so the sim is fine)
Flashed modem from RETAIL instead of RETUS. still no LTE.
Restored TWRP backup of Lineage... of course, no LTE.
Just for giggles, I put my wife's sim card in to test. still no LTE.
My guess, baseband issue?
If I select LTE under preferred network type, I get LTE, but phone and SMS don't work.
If I have it on Global it doesn't work, if I have it on LTE/CDMA/EvDo/GSM/WCDMA I get phone and 3g but no LTE and a lot of times the signal just drops.
Anyone have ideas?
I have a EU version (XT1955-4), and I didn't get any modem or GPS with lineageos. Since I had flashed lineage to slot b and I had overlooked the "copypartitions" part, the modem didn't work at all, since it was an old version or the wrong one.
I did the following:
- Downloaded my "stock" firmware version, for me RETEU.
- Boot to fastboot
- flash the following from the stock firmware zip to current slot:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
Modem then worked including LTE. My guess is that "RETUS" should be the correct one in the United States.

unfortunately I have tried that, and to no avail.
Are you sure you flashed it to both slots?
Pretty sure. I'm thinking I might try a full wipe using the Lenovo software first, and see what happens. When I select in the options "CDMA/EvDo Auto" I get 3G with phone, and when I do "LTE" I get LTE but no phone. I have no options for VoLTE in the settings. Global won't connect to anything. So It's obvious that the OS/firmware is capable of connecting to the specified bands.
