Service Not Available, Service Provider KTtwophone.... (FIXED!) - Verizon Samsung Galaxy S6

I flashed the official nougat image (QD1) posted on the forum, device failed to activate and has no service, KTtwophone shows up in settings as well as the subsettings making no sense...
THIS WAS RESOLVED BY FLASHING LOLLIPOP (OK7) IMAGE AND USING OTA TO UPDATE!

New ROM update?

Is there a new rom update for our phones and what changes are made to our phone with that new rom?
I went to the htc site and there is a new rom of 1.08.573.2. Is that correct?
Yes, that is the last official ROM release.
I have an htc touch pro bought in Greece. In the support page of O2 there is an update ROM (5.12.206.1) and my serial number was accepted. The question is "Do i need hard-spl or i can just flash my phone"
For official releases, you only need to flash the phone.
When trying to update the rom I got an error message saying: Error [294]: Invalid Vendor ID. I think this rom is for US cellular customers and its not for the sprint customer.
Any ideas on what might be wrong?

RefurbishedV10 fingerprint/security issues after upgrading from lollipop to MM

I've seen many threads about this issue originating because the apparent H900 model for some people turned out to be a different model somehow converted to look like this, and everyone had the exact same issues as me, namely
1. LG VPN has stopped working error
2. Fingerprint/security tab causes settings to crash
3. Attempting to uninstall apps causes instant soft reboot
Some folks mentioned fixing their phones by finding the actual model of their phone and flashing the correct firmware. But AFAIK, no flashing software allows flashing of a different model. And none of them was clear about the actual steps they did to fix it.
Since I'm on Marshmallow, I cannot root, and I cannot rollback to the firmware I had in my phone.
Can anyone please share how they fixed their phone or someone expert in the matter?
Warranty/Motherboard replacement are out of question for me.
Any help is appreciated.
Same here please somebody help.
Same, did you find a solution? :/
same problems
Same probleme... Any update for this?
I see on AT&T website they have been rolling out the software update ver. H900z in USA only?

Finally Found 1000% fix for all this type of issues. Security Menu to App Uninstall all-everything OK. Just need to flash an special modified firmware based on VS990 Hardware. The current Firmware version is Android 6.0.
NB: This is not for free and not for individual one. $150 will cost this type of firmware. So, this solution is for Service Personnel or Professional's only. Contact me for details on Skype or Gmail (rassel2k). Goodluck.
Too bad the price of the phone itself, 2nd hand (H900,H901,VS990,F600), is around $100 here.

Updating unlocked s9+ (sm-g965u1)

Hi have the original US sprint version of the samsung s9+ which I had recently unlocked and unbranded from an unlocking service through team viewer. The model number is now SM-G965U1 and the baseband version is G965U1UEU3ARG7. I noticed on websites like sammobile that there are updates to this software for this phone model. When I click update software on the phone it states that I have the latest one. Is this normal or should it be able to update to later firmwares such as ARK5? I am using a t-mobile sim card in the phone currently. Any help would be greatly appreciated.

OTA software updates are controlled by your carrier, in your case, it is T-Mobile.
If T-Mobile does not offer an update for SM-G965U1, you will not get a notification to update and it will not find any updates when you check for them.
But, if there are updates for that model number available to download from Sammobile, just download the firmware and flash it via Odin onto your device.
Note:
When the unlocking service unlocked your device, they might have only used a small part of the software from S-G965U1 and not the entire firmware because the entire firmware might not be compatible with the model that your device originally was.
For example, they may have only used the bootloader from SM-965U1 or only the system.img or only the modem.img or any combination but not the entire firmware, if this is the case, flashing the entire firmware might cause issues.
I would email the unlocking service and ask them if the entire SM-G965U1 firmware can be flashed or at least ask what files were used in the unlocking process and which parts of SM-G965U1 firmware are safe to use or not.

Hey thank you for your response. I just spoke with them and they said that the full software was used and that I would get OTA updates? Even if I do flash the firmware, am I able to jump to the latest firmware or do I have to flash all of the firmware in order to get to the latest one?

I don't think you understand how things work when it comes to updates on android devices. It isn't like a Windows PC where any and all new updates are offered/pushed via Windows Update to every device that has Windows installed.
OTA updates are controlled and offered by your carrier, you will only get the update if your carrier CHOOSES to offer the update to devices on their network.
Just because your device manufacturer has released an update, does not necessarily mean that your specific mobile carrier will offer it to their customers, some devices never receive updates from the carrier for "this" or "that" device whereas other carriers would offer the update to those devices.
It's all a matter of who your carrier is, not what device you have.
For example, Samsung could release an update for S9+, then "this" carrier could choose to offer the update to the S9+ devices on their network and they would be able to update via OTA update through system settings.
Or
Samsung could release an update for S9+ but "that" carrier could refuse to offer the OTA update to devices on their network. In this case, the device can still be updated by manually downloading the update via the internet and then manually flashing the update via Odin, instead of via OTA update through system settings.
To put this in perspective in comparison to a Windows PC vs android, if Windows Updates were handled the same way that android updates are handled.......
The way android updates are offered by your carrier, for Windows PC, the equivalent of this would be Microsoft offering Windows Updates but then the updates only being available based on who your internet service provider is. In this theoretical example, your internet service provider may or may not allow the update to be installed on your system. If your service provider doesn't allow the Windows Update to be installed through their network, you would have to manually download the update and install it yourself instead of using the Windows Update Service to install the update automatically.
Does this help you understand how the update system is handled when it comes to android updates?

August OTA bricks modem “Invalid SIM”

Hi everyone,
In August I received an OTA for my SM-G955W. I installed it and immediately after it rebooted I got an “Invalid SIM” error message.
I took my SIM card out and put it in another phone and it worked perfectly. I put another SIM in my phone and it gave the same error. So obviously the problem was with the phone, not the SIM.
There is a Reddit thread dealing with this exact problem.
https://www.reddit.com/r/GalaxyS8/comments/i9b58o/invalid_sim_card/
I managed to get my phone working by flashing an older modem version using ODIN as was suggested in the Reddit thread (posted above). But now I cannot get any future OTA updates because it says “Your current software version issue supported”. Presumably that is because I have a mismatched modem file flashed.
Is there any way out of this?
Is there any way to get LineageOS on this device? It is a Snapdragon processor and I think the unofficial LinageOS builds only work on the Exynos models. Or is that incorrect?
Thanks,
The Fish
Flash with odin original firmware for your country and carrier sammobile.com/samsung/galaxy-s8-plus/firmware/#SM-G955W .

Any firmwares with VoLTE enabled

I'm trying to re-enable VoLTE by reverting the firmware back to Stock 601SO JP Nougat though during bundle creation, SMF prompted that carrier.sin isn't included in the 41.fsc flash script file. Ofc I didn't include it at first because it might lock my device back to the carrier who issued it - was unlocked before so I'm not entirely sure. After flashing Nougat 601SO (with *.ta and carrier.sin excluded), the setup screen is spazzing out with a window saying "ChameleonWorkload" stopped responding. I'm currently using Stock F8332 CE1 Oreo. So...
1. Is carrier.sin responsible for the "ChameleonWorkload" ANR spam?
2. Are there any stock F8332 firmwares that has VoLTE enabled?
According to a post from another forum, it can be done by using a firmware from another region (or carrier-specific)
