[Q] No Signal, Baseband Version unknown

Hi,
I am not sure what the issue is, but I unlocked the bootloader, rooted my Dev Edition XT1053 and now I can't get signal on T-Mobile. I installed TWRP 2.8.1.0 and then Dirty Unicorns 8.0 (4.4.4). I see in settings->about phone that "Baseband Version" is "Unknown". Did I somehow erase my radio?
I tried searching around for reverting back to stock but seems that there is a risk of bricking in case of downgrading. Not sure if this applies to downgrading from a 4.4.4 ROM or not. But in general, I couldn't find a radio image for this phone.
Any ideas on how to proceed?
FYI-- wifi works just fine

Download the factory images for your device and android version and flash the radios with these instructions. I see you are not on Verizon so do not use the radios in the post I linked. But the post I linked will give instructions on how to flash your stock radios.

switched to pacman rom, now baseband version was listed as
2323.020.90.00R
but still did not get signal
flashed the radio from 4.4.4 TMO retail and baseband version says
2323.038.123.00R
after that, worked perfectly fine. thanks for the help!

[Q] XT1097-converted-to-Pure Edition doesn't recognise my SIM on 5.1

So I have a Chilean XT1097, which I converted to Pure. To update it to 5.0 I needed an EFS backup; if I didn't restore it I'd get a "no signal" icon on the status bar, along with no IMEI and an unknown baseband version. If I restored the EFS backup everything was fine. The thing is that I just updated to 5.1 using the OTA, and whether I restore my EFS or not does nothing; I get something even worse; status bar has a "no SIM icon", and along with the unknown baseband if I hit the IMEI combination on the Dialer instead of showing me a simple "IMEI" screen with no number, as it did on no-EFS 5.0, the app now crashes.
I've tried the following:
Updating from 5.0 with EFS restored
Updating from 5.0 with EFS restored, restoring the backup again on 5.1
Updating from 5.0 without EFS restored, restoring EFS on 5.1
On 5.0 with EFS restored, backed it up again (since previous backup was in 4.4.4), updated to 5.1, restored backup.
None of these work. Any ideas?
Thank you.

I have an XT1097 from Telus in Canada. with 5.0 I could use the modem from my providers 4.4.4 or 5.0.1 build and it worked fine. When I tried the original XT1095 5.1 soak the modem worked without any issue. I assume maybe that was simply because it was a soak test. In the final version you're using it sounds like they went back to a model specific modem again. It probably isn't compatible with a 5.0.x modem which is why it doesn't work for you. You may have no choice but to wait for 5.1 from your provider to use it. If I get time and feel like playing I may give it a shot myself this weekend.

Yup, this seems to be the case. I don't have the original ROM my phone came with, so I guess I'll flash the Brazilian 5.0. I hope that when it updates to 5.1 I have no modem issues (for what it's worth, updating to 5.0 didn't require me to restore my EFS backup!).

Which phone model and provider do you have specifically, I can look for the 5.0.x update for it assuming there is one.

XT1097 on Movistar Chile, latest there is 5.0.2. Shouldn't I need a 5.1-specific modem, though?

Most likely but I figured it would be nice to have the original 5.0.2 for your specific phone but I don't see it in my list of firmware.

Yeah, I couldn't find it either. The closer I got was the Claro Chile (the only other carrier that offers the phone here) 4.4.4 which, due to a falling out they had with Motorola up there in Mexico, stopped selling and updating Motorola phones.

Alright, the solution is to never restore EFS. I suppose it can also be accomplished by flash stock modem and fsg on 5.0.

I just flashed the 5.1 pure edition over my XT1097 and everything is working great because the update has the bands of almost all the major carriers. If you update and you lose signal, data or IMEI just flash the modem of your original version and everything should work.

did you flash the XT1093 firmware 5.1 and you lose signal? weird, because is the official for you model
http://www.filefactory.com/file/1fib372p0cbv/VICTARA_USC_XT1093_5.1_LPE23.32-21.3_cid9_CFC.xml.zip
I flashed the XT1093 version months ago over my 1097 because was the first to get 5.0.2 and stuck at "registering phone, please wait", what I did was to dirty flash over different version.
I understand that CDMA supports diffrentes bands but as I said, if you lose signal after the 5.1 update just try to flash the modems of the 5.0.2 or 5.0 of the XT1093

yes i flashed the original one... i even ota updated it.... seems to be problems with that version. not losing signal, only cant connect to data/internet.

Galaxy Note 4 SM-N910T 4.4 - Can I Flash 910F ROM?

Flash N910T with F910F ROM
Hello guys, I need your help. I got as I thought SM-N910F brand new in Russia with 4.4 KK. It worked fine except for being weak to work with 3G. 4G was OK. Russian localization was OK. When I tried to update the ROM, I discovered this device is not 910F but unlocked 910t instead. While experimenting with flash, I damaged efs. Then I restored it with Kies flashing stock ROM. So now I'be got lollipop phone which says "insert T-mobile SIM".
SI my idea is to flash it with some European ROM which support Russian language. Possibly, some 910f mod? Can somebody suggest which ROM to flash? Unfortunately, I didn't backup original ROM.

You cannot flash a N910T phone with a N910F custom or stock twrp flashable zip file rom.
What you need to do now is to find, download and ODIN flash the official firmware which
came with your phone in order to get your phone working properly again.
Sorry about that,
Have a great day!

Thank you, Misterjunky. There is no such a thing as "official firmware" for my phone. Because it was brought to Russia and unlocked unofficially as I can see now. They even changed the phone label on the back side. So they flash some custom firmware, I think so but I have no idea which one.

To put it more clear, what i have now is exactly official firmware. I've got it with Samsung Kies Tools - Firmware upgrade and initialization which downloads the official firmware based on model name and serial number. But unfortunately this is not what I need because it doesn't accept my local SIM

No signal after Android 6.0 update

A few details:
First, I'm running 100% stock everything. However, this issue has also happened on Cyanogenmod 13, and both Motorola support and my carrier aren't very helpful, telling me to clear the cache which obviously hasn't worked.
I did an OTA update from Android 5.1 and I get no signal at all now. I have no idea why this is, it only seems to occur on Android 6.0.

What model is your device? Have you tried just flashing the modem files for your device?

Apologies, I should add this as an edit. Model number says Moto X (2nd Generation), System version 24.11.18.victara_tmo.tmo.en.US tkpca. Not sure what else you need, modem files have been reflashed but still no luck Out of ideas.

what is "tkpca" end of system version? Telus ? And this FW is for T Mobile XT1095. I guess your phone is XT1097. Maybe you flashed wrong FW before update . You should flash right FW or you can flash only modem to get signal back

It worked on the 5.1 FW that I flashed though, and doesn't work on any version of 6.0. I flashed the FW provided by Moto on here:
https://motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images (Moto X (2nd Gen) Pure Edition: L-5.1-LPE23.32-21.3 TMO)
(And yes I have reflashed the modem)

I had this issue too with the OTA I received on xt1092 EU. I reflashed the modem with 5.1 fw, while keeping everything else on 6.0 fw. Worked for me, might work for you too. Good luck.

I have the same issue, on what I had thought was an EU xt1092. I uploaded the xt 1095 5.1 stock files to it a while ago and rooted and it has been fine. Did Marshmallow original OTA yesterday and it's lost cell signal. Some more investigation shows the imei of the phone to a be a AU variant! Wasn't expecting that. Reflash to xt1095 stock 5.1 bought service back again. Have tried a few different modem files, But I can't get signal with 6.0. Any ideas? Or any magic modem files . I also can't sideload the EU 6.0 OTA, it fails with signature problems.

I'm experiencing the same problem. I received the OTA a few days before Christmas, and now I'm still without signal. Just tried flashing Android 5.0 modem partition (from Motorola), but it didn't work.
My phone is the XT1097, but everywhere I searched said that the XT1097 and XT1095 were the same phone. I'll try flashing the modem partition from the 5.1 recovery image, I'm just waiting for Motorola to give me access to it.
EDIT: and yes, I flashed 5.1 from Motorola and it worked like a charm. Then OTA came and it messed up my phone's signal.

I have 5.1 modem files from moto for the xt 1095 and they haven't worked for me .
StillBrilliant, did you have the 1092 modem files or the 1095 ones? If you have 1092 is there any chance you can post them.

Just flashed the 5.1 image modem, and it still doesn't work. Any ideas?

You need the xt1092 modem. However there is more than one xt1092. Do you have reteu, retes, or retde?

My XT1097 is from Brazil, no carrier, bought it directly from Motorola's site. The weird thing I've found is that the update version has retbr in its name.
EDIT: fixed it. Found a thread that had the retail images for XT1097. Downloaded the Brazil version and flashed the modem. It works now.

I thought mine was a reteu, but not so sure now.... Imei listed it as an Australian phone! (I bought it from someone who reviews tech) I am in the UK, but now not so sure which modems I need!

Ok, here is the full 6.0 for reteu:
http://www.filefactory.com/file/6q0pj4hr2sh5/VICTARA_RETEU_XT1092_6.0_MPE24.49-18_cid7_CFC.xml.zip
Use the commands in fastboot:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
That should get you back on the correct modem for your phone. Or if you want just flash everything in this zip to be 100% stock 6.0 for the reteu model.

Thank you, I think I might flash the whole thing back to stock with that and start again.

As a bit of a newb here, the fastboot system system.img command isn't working for this chunked image. What is the system image command for sparse, or the quickest way to rechunk them together. I've been searching but I have come up with about 15 different methods!
By the way, flashing the modem files from that image worked. Thank you but I would still like to go back to stock.

Same issue signal drop after upgrading to 6
i am having the same issue after upgrade to 6. Signal drops a lot. Works fine when connected to 3g or 4g networks, but drops to 2g networks. What could be the reason.
