So like the title says, I'm having an odd issue.
I had previously rebranded my device to ba VKY-L29C432 to upgrade to Oreo. All was well, but finally there was an official Oreo build available for my device variant, VKY-L09C654. I went ahead and restored my oeminfo partition, and installed, but I am now showing Dual SIM options.
I went ahead, and completely deleted all partitions except the oeminfo, and downgraded back to Nougat on my carrier's stock ROM, then upgraded to Oreo on my carrier's stock ROM as well.
However, I'm still seeing dual SIM options. Is there any way to correct this?

After trying to install few custom ROMS namely DR. Ketans and SimplRom I experience SIM removed error problem.
The flashing goes fine with full factory reset (only internal SD is not wiped), I enter the PIN when I'm asked for it. The SIM is unlock but when the phone registers on the network it gives SIM removed error and forces a reboot.
I also upgraded the bootloader and the modem to the latest versions BL_N910FXXU1BOD2 and CP_N910FXXU1BOC4 but the problem remains the same.
When I restore back to the original ROM (backed up by TWRP) everything works fine. If dirty flash custom ROM over it again there are no problems with the SIM card.
The only conclusion is that T-Mobile has some additional software installed.
The phone is SM-N910F bought from T-Mobile. It has T-Mobile branding on boot and shutdown.
Does anyone now anything about this ?
To update it with my own research.
Apparently the SIM card is lock to Macedonia region. MBM CSC. When installing custom ROM the CSC gets changed and the phone rejects the SIM.
In an effort to resolve this I've flashed DE DBT CSC ROM and the phone won't accept my SIM card.
Currently I'm downloading the original T-Mobile MKD firmware and I hope by restoring it that I will be able to use the phone again.
Also since I paid for the phone in full I intend to contact T-Mobile tomorrow and ask them to unlock my phone.
Will write what comes out of this. Don't want someone else to lose their nerves as I did today
Definitely the issue was in wrong CSC. I've downloaded the original firmware and everything worked again.
But I couldn't stay put and wanted to flash a custom ROM so I went with http://forum.xda-developers.com/note-4/snapdragon-dev/rom-bob4-devbase-multi-csc-safe-bloat-t3033881.
It's a great base ROM stripped of Knox and de-bloated. Most importantly it keeps your current CSC intact.
The procedure was:
Flash original firmware with Odin,
Root with CF-Auto root
Flash TWRP recovery with Odin
Reset data so that it completely goes stock because flashing the original firmware doesn't reset data
At this point I made full nandroid backup
Flash ALEXAND ROM
Uninstall additional bloatware
So far it's working fine.
I hope that this will help someone.
So I tried several ROM (CM13, Google EUI, Stock) when I tried to revert back to stock. Immediately after rebooting I noticed an issue: the bootloader was in Chinese. I thought it might be fine, but when the phone booted up, the SIM (AT&T) was not recognized. The option for "Mobile Networks" is grayed out and even CM (from a backup) has this issue now. I already flashed the US Modem zip and it is still occuring. Anyone able to help?
Update: Fixed 100% by flashing old stock firmware of EUI and OTA updating to 20s. Bootloader and modem fixed.
Hello..I bought A2017 and asked the selller to upgrade my phone before he send me the phone..so i received A2017U b19 with nougat 7.1.1 , then I got the problem as any sim card doesn't work, it says no service
Please help me what happened to my phone and what should i do? Thanks in advance
flash a2017 full firmwware, or flash only modem, for the last you need an unlocked bootloader and twrp...
the easier is to flash a full a2017 firmware, get phone working, then mod anything you want
Could you tell me all the steps? I never do those things before.
Are you on Verizon? If so, the solution is put a GSM (for example, T-Mobile or AT&T) sim card in your phone, restart it, then put your Verizon sim back in and restart again. You can get GSM sim for cheap on Amazon.
If this is your problem, you don't need to unlock your bootloader or flash anything.
Hi guys, i have a xt1626.
And for some reason last night I lost my network signal and SIM 2 status.
Well... I made a factory reset and flashed lastest stock rom (december 2017).
But it still not work.
SIM 1 is working IMEI is correct. but no signal. Only showing "No Service". SIM 2 is missing.
When I see baseband it shows lastest baseband but not with "DSTV RET_BR..." on final. It show "DFLT_FSG".
I flash modem, install others rom (custom) but nothing works.
There is a chance that make it working again?
Are you sure you have flashed the correct version of stock rom.??? This happened to me only when I flashed the ROM for another variant!
I flash this one: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
After some google search I found the problem.
The mobile radio is not turning on. Like if the phone still in airplane mode.
i don't know what i have to do. No looks like HW problem cause sim card is recognized
There is a place wich i found specific firmware for xt1626?
firmware.center only have universal firmware.
That link doesn't have the firmware for 1626.. there was a file factory link that had all the variants stock ROMs.. So if you find any nougat version you can flash that barring bootloader and gpt.bin as downgrading them will result in a brick! And then take OTA!
Hi, i have a H870 which was good until i flashed a H870DS rom.. it was all working, also with wrong stock, but after this mistake i decided to return back to correct stock.
Network connection is not working anymore. It doesn't even connect to the network, nothing.
It says only "service unavailable or "no service" (depends by how it should be translated from italian )
Today i decided to flash a H870s rom, so dual sim again, and it works! i don't know how, but my h870 has become only dual sim. No way to return back to h870 stock with network working.. Tried everything, flashing 200gb of rom stocks but nothing. Now it works only on dual sim variants' rom.
How can i do? I want it back to single sim, also because i want to flash a different rom which not works with dual sim stock,or better, network will not work.
Tried modifying network mode by *#*#4636*#*# but nothing.. imei is ok.
Thank you.
Why did you flash DS ROM over H870? Why would anyone do that?
It was a mistake, i used it for error
Flash stock with lgup
Ahahah come on.
I said i tried everything wirh all softwares and all roms.
