Well, what is left for me is to asume that the cel. provider blocked you, or the phone, unfortunatly, is malfunctioning.

Maybe I got a defective product. I flashed using miflash tool and having the same issue. No sure what else to try.

It`s sound like you should contact Xiaomi directly to solve the problem.

maybe you should change the SIM card to another phone to make sure that the SIM is ok first.

i had this problem once after getting my HOX. did hard press on the back cover and it did can detect sim card. also, when from flight mode to normal mode, it seem can temporarily detect my sim. what i did was affix a small patch a layer of tape on the back of the sim, and inserted it back. since then no problem arise

Can you change the network operators on 8.1?
Is your unlocked Pixel XL from the USA? It seems it doesn't support the correct bands for your network
All pixels have the same radios. Dial *#*#4636#*#* click on phone info. Change settings if needed
SIM card is toast. I have had this exact thing happen to me. Just go into a VZW store and request a new one. Sim handshake needed for LTE connection only on VZW.

I'm on the February patch, stock. I'm flashing everything, also, is it normal for your phone number to not be your phone number with a new sim?
My number showing up on about phone is 908-770-6054. This is not my number, could it be human error?

Contact your carrier or go in and tell them that it is not your number and that you are stuck on 2g they should be able to tell you how to fix it or if you go in they can fix it
I did contact my carrier, they cannot figure out what to do. Replaced the sim about 4 times, still no luck. I go into testing (secret code) and I am on 1x network @loeffler23
Sounds like your efs data could be corrupt and there is no way to fix that. Or your LTE radio is toast. Did someone try to carrier unlock your phone?

my phone's unlocked by default and there has to be a way to fix efs, not accessible by recovery? (what is efs)
It holds the imei and other radio proprietary info not sure what partition that data is actually in on this device. I think the efs data is no longer in /efs
Twrp used to have a option for efs backup with the data system backup and restore options

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.

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.

A hard reset wipes the data partition, so if your system partition is corrupted from an update or something, it won't help. When you flash it, it rewrites most the partitions.

Any day, man.
"The phone is not allowed" Isn't this Cause 6?
In Touchwiz (stock) ROMs, check with *#9900# > cp log > copy to SD card > look at the internal storage > log > err > litmuslog. If it shows #Cause:6 in this file, this is most commonly sent for imei blacklists, contact both mobile network operators.
No work after firmware reflash .
Any suggestion?
Need help.
The Samsung answer is take it to service.
But why when with nougat working and with oreo didn't!!!!!!
I was at samsung service only to ask ,the answer is :the probably cause is software or the mainboard !!!
And they said for Romania there is 9 firmware!!
At sammobile site was only two,where do i get the rest?

You can also grab firmwares from samfrew (SM-A320FL). Do you get any error code besides "the phone is not allowed" like "phone is not allowed MM#6" or "phone is not allowed MM#2"?

Alright. As you said while roaming I guess your IMEI number got blacklisted in that country you are. If you bought your A3 new and same error occures without roaming then only Samsung support center can fix it.

Used MSM tool backe to T-Mobile 11.2.5.5 and still same problem, sim card can be read but no signal. Flashed T-Mobile modem but modem b failed, it says no such partition.
Bought this phone from third party. Any suggestion is appreciated.
