Baseband not found IMEI unkwon

Hello everyone, I have a Moto Z2 Force XT1789-06. I had updated the firmware and after that the phone is working but the baseband is not found and the IMEI is unknow and of course there is no wi-fi and no carrier signal. I have already tried to flash the original retail firmware and it can be installed accurately but the baseband and IMEI are not identified.
Do you know how can I repair it?
Thank you.

I solved the problem. You can close the discussion.

He asked how, not if you did. Usually on this site it is advised to share you solution so if someone else is trying to fix the same issue they can try what you did.

What problem do you have? "imei unknow" or "baseband not found"? What did you do exactly on the phone?

Well I had the problem of baseband not found but I could solve it, I still continue without a mobile network although the IMEI does appear. The only thing I did was update from nougat to Oreo. The phone is the AT & T variant and is unlocked for all networks. Any solution to have mobile network again?

Have you tried installing the latest version of the AT&T OCSX27.109-47-14 firmware? It also happened to me not to have a telephone network and wifi. It is caused by the wrong NON-HLOS.bin file.

Yes, that version is the one that installs first now I am with the OPXS27.109-34-15. I'll try flashing the stock ROM maybe the problem is solved.

I managed to get myself in this situation this weekend... When I start my phone in fastboot mode it shows "baseband <not found>" and when I start it I get no wifi or network.
I've flashed almost every Retail firmware from this repo to no avail: https://mirrors.lolinet.com/firmware/moto/nash/official/RETAIL/
Any particular version I should be installing perhaps? Could I install another version that is not retail? Mine is the -05 variant.

How can I update my unlocked AT&T S9 (SM-G960U)?

Hi. I have an AT&T-branded unlocked S9 (SM-G960U) and I have not been receiving software updates. The date of the installed security patch is Nov. 1, 2018, and I'm still on Android 8.0. When I check for updates, it says that my phone is up-to-date. My current carrier is outside the USA. I have also tried updating via Smart Switch but it also says my phone is up-to-date.
Is there any way I could get the Android Pie update?
Thanks for the help!

in short, the U1 is a debloated version of stock without the carrier junk. The different iterations will have different modem files that are intended to work best with the respective markets they are built for, globally speaking. Samsung stopped making a separate version for the GSM carriers in the USA with the S8 which is why all the stock image files are now cross compatible. They technically always were, its just that theyre far more interchangable now due to this physical difference no longer existing

So do you mean that the different carrier versions of U1 firmware don't have carrier apps, but have files that make the phone more compatible with the carrier's network?

It seems as though AT&T can only send updates over their network, which I don't have access to because I'm outside the US. If I change my firmware to U1, would I then receive updates OTA in the future directly from Samsung?

they have very minimal bloatware, they might include carrier apps, but very few. They usually have carrier specific radio firmware to allow the phone to operate best on that specific network, yes.
i would flash one in the very near future myself, but im about to head to Mexico on vacation, so im a tad paranoid to do so. Ill do it when i get back tho. By the end of this month, ill be running a U1 firmware set

Can't update to Android 9.0

I just bought samsung s9 SM-G960U but can't it won't update to android 9.0 manually ! it says processing failed
I did some researches I found that it's carrier-related . Some solutions suggests that I use odin to update but I can't choose the right firmware !
In fact :
- when I try to check the csc using *#1234# it show g960usqu2are6 ( I think it's Verizon using google)
- when I log on into samsung website and enter my imei . The product info shows that my carrier type is Sprint
- when I check "about phone/service Provider SW " on my phone the first line contains TMB after G960U and the third line is TGY/TGY/TGY
I'm confused but I want to update my s9 to android 9.0 . Help me

get the firmware here
https://www.sammobile.com/firmwares/galaxy-s9/SM-G960U/VZW/download/G960USQU4CSC7/265795/
get the most recent version of Odin (i didnt source you a link for that)
open Odin on your computer
unzip the package and get your phone into download mode, connecting it to your computer. Allow drivers to install and when Odin recognizes your device by showing a random number in the port field. Then place the files in their corresponding spots in Odin paying attention to which CSC file you use as one factory resets the phone and the other simply applies the update. It is recommended to use the factory reset CSC when changing from different iterations of the Android OS. Press the start button, allow it to full run the firmware push. It will then automagically reboot (yes, automagically), and youre done.

Once a phone is unlocked, it stays that way forever. Firmware has nothing to do with a phone's locked or unlock status.

Depends how it was unlocked, seen a few members flash new firmware and the phone is SIM locked again, these unlock companies must use some modification to the firmware rather than unlocking it properly

Good to know. Wasn't aware that a phone could be unlocked with firmware alone. I guess it's a temporary overlay or something that "fakes" being unlocked?

Yea must be something that emulates the unlock somehow but once reset or flashed it's gone, always seems to be people who have bought the phone second hand unlocked, it has worked fine with their sim until they reset or flash different firmware, then it's locked again

Need Android Pie firmware details for Unlocked T-Mobile Samsung S9

Hi All,
I have Samsung S9 Unlocked T-mobile from US and currently in India. Currently i have Oreo Version.
As all know, it doesnt have VOLTE option enabled which is needed for my sim network for voice calls to go through.
Somewhere i read Pie update will have VOLTE option and hence i am trying to update to Pie update.
I downloaded G960USQS6CSGB firmware for T-mobile, but before upating firmware using Odin, i got doubt if it will stick to T Mobile after update. This will make my phone not usable in India.
I tried to check online, but couldnt get direct answer and hence posting in new thread.
Can someone help clarify if it will lock the mobile to T-Mobile or will the phone be still in unlocked state?
Also i see two CSC files in the firmware folder. CSC and HOME_CSC. Which one to use?
If I should update with some other firmware for being unlocked and yet to get PIE update, please point to required firmware name or links.
Also will updating to PIE update will have VOLTE option ? Kindly confirm.
Thanks in Advance.

csc will factory reset your phone, home_csc wont
volte wasnt removed from pie, so that shouldnt be an issue
the firmware version you posted has the 6th bootloader revision, im betting here is a 7th available for your phone, but the 6th version should be fine as well
as far as the unlocked state of the phone goes, it shouldnt re-lock, but im paranoid lol. Have you looked into the U1 versions of the phones firmware? Theyre inherently unlocked firmwares and dont have any of that irritating bloatware **** in them

if it has no financial obligation to any carrier and the phone locks to that carrier, then the carrier it locked to would be required to release it. I cant imagine how it would lock to t-mob tho

Factory unlocked phones stay unlocked, no matter what firmware you flash.
Carrier locked phones that were properly unlocked by the carrier (they provide the code to SIM unlock the phone) will stay unlocked, again, no matter what firmware you flash to it - as long as it's compatible. Flashing the wrong firmware may just brick the phone. But, at least it's still SIM unlocked.
Phones that had some kind of software hack installed to trick the phone into thinking it's unlocked will lose the unlock status when you flash a firmware that also wipes the phone. Then it will come back as carrier locked again, because the hack is gone.
That last case is the only case I know of that will "re-lock" a phone. I've never heard of a carrier unlocked phone spontaneously re-locking under any circumstance.

Hi,
Thanks for the details. I tried to flash G960U1UES6CSG4_G960U1OYM6CSG4_XAA firmware. But while loading AP file in ODIN, it gave some error. Couldnt understand what is the error as its in chinese.
Then i loaded G960USQS6CSGB_G960UOYN6CSGB_TMB firmware which i downloaded previously. This got loaded in ODIN without any issues. And i am able to flash to phone. On rebooting, saw that phone moved to Pie version.
But i couldnt find VOLTE option (Enhanced calling) option. Does anyone know which version will enable that option?
Or anyother way to enable that please.
Thanks in advance.

if your Odin error messages are in Chinese, youve obtained a modified version. Itll probably work, but youll get that Chinese stuff whenever it needs to tell you anything. I dont know which versions have volte tbh. Sorry man.

if your Odin error messages are in Chinese, youve obtained a modified version. Itll probably work, but youll get that Chinese stuff whenever it needs to tell you anything. I dont know which versions have volte tbh. Sorry man.

Thanks youdoofus for trying to help. For me atleast it didnt get locked when i moved to Pie. I will try other methods.
I will try to root the phone for enabling volte, but the methods that i tried didnt work.

yeah, sort of. The CSC's on these things are weird. Im starting to believe that these new versions of android are just like windows ISOs where they have all the versions compressed into one file and it uses a directory file to tell the firmware which version to install. Im sure a code writing dev can confirm or deny this thought, but at this point its merely a weak theory

CSC Change is still possible?

Hey Guys,
Just wanted to check whether any working methods are around to change the CSC of a Note 10+
Couldn't find any guides apart from the ones which are in Note 9 Sections.
Any support on this is much appreciated!

Im also looking for a solution for this. SamKey's paid service is apparently supporting this but im unsure of the method their software uses and its a paid service. Users in Australia (like me) are having issues with RCS services through Telstra (TEL) because the Open Variant bought direct from Samsung not having the correct CSC. Some users have reported changing the CSC through SamKey successfully.
I have tried flashing with Telstra firmware but no luck.

I initially did *#272*IMEI# and was able to switch between CSC. When I switched to XAA, I was stuck and could not able to use the *#272*IMEI# anymore.. So I had XAA/XAA/ATT.. I saw many were stuck.
Found a solution that worked for me is as follows. Try at your own risk.
Downloaded the tool from
https://www.mysterious-dev.com/2020/05/changecsc-all-samsung-free-tool-android.html
and downloaded the ChangeCSC Software tool.. . watched the video couple of times.. The process lets you install custom THEME.. I was getting "Update" "Delete" and "Buy" ..
What did was
install another random theme
then went back to the program and clicked change CSC again
this time when I choose the custom theme pack, I saw the "Try now".. after that I followed the instruction to about phone->legal and clicked on CHANGE Carrier Android 10 and VOILA!!! I got that CSC change page.. I saw XAA was selected and I changed to TMB... after that "Sales& Network Code Change" and clicked ok.. .The phone restarted and saw the T-Mobile logo!!!!
I even tried the *#272*IMEI# and this time it worked and showed me the CSC screen!!!
Hope this helps anyone who is stuck...My phone now says TMB/TMB/ATT!!!

Hello,
Prior to doing the process. I used smartswitch and backed up my phone completely.. I also did factory reset the phone.. *** Since I was going to use a new method/tool, I was not sure so wanted to make sure it does not interfere with any existing account/app on the phone. Once I was able to get to the CSC screen and changed to TMB, I went back again to make sure do a factory wipe and start complete fresh out. Hope this helps. Good luck!

The Mysterious Dev tool that you mentioned, when the tool was changing the CSC, did the tool factory reset your phone and wipe it?

hmm.. don't recall if it wiped.. I already had T-Mobile sim inside.. so when I saw the CSC selection page and as soon I choose TMB it restarted and came with T-Mobile splash Page, at that point I know it worked, so before even finishing up the boot process, I rebooted in recovery and did the factory reset

I had to do the CSC changing today and it simply rebooted and displayed the new CSC logo. It was with AT&T and when I change it to TMB. I get the T-Mobile boot logo.. I was able to get back in to the device without loosing any data.. The CSC showed TMB/TMB/TMB.. But I noticed the ringer/notifications sound still remained the AT&T settings. So to answer your initial question, my phone didn't get wiped out when switching the CSC.
Thx

After changing your CSC to TMB, are you getting TMB updates (OTA) or ATT updates?

I have found *some* Samsung models can still change CSC via firmware flash in Odin by following these pre requisites...
- disable find my phone
- sign out of Google and samsung accounts
- developer mode .... enable oem unlock
- flash a single CSC stock firmware in odin (do not use home-csc)
- phone will be completely wjped but after first boot and running setup, CSC will be change to match new firmware

Have any one tried
