Hello Xda
I recently unlocked my device with the regon away apk. all went well, downgraded to mf3 modem and unlocked, however after unlock, all i get is edge internet, no lte or H+. I think i tinkered with the utms and set it to gsm only before unlocking, i dont know if thats whats casuing the issue but please someone help.
Try reflashing your modem and moduels? If worst comes to worst reflash your firmware. Once you sim unlock it wont go away even if you reflash firmwares via odin.
Hello, after receiving the wrong phone from Amazon twice now and them saying they won't be able to get me the H918 after that, I may just stick with the H910 instead of switching to another device entirely. I want to switch firmware because from what I am seeing online in a few people, AT&T has hardcoded stuff in the H910 ROM that is causing the two main issues I'm having with the phone (I returned it already, but I can order it again if I'm able to switch to the H918 ROM): Sending and receiving MMS does not work, and tethering/WiFi hotspot does not work, because both are trying to connect to AT&T's services when I am on T-Mobile. Anyway, back to the original point: Would I be able to put the firmware for the T-Mobile (H918) version on the AT&T version (H910)? And if I can, how?
Guessing it would be safe to assume nobody really knows?

No, you cant because they are not exactly the same phone internaly, because tmobile doesnt lock the bootloaders on their phones. AT&T and Verizon phone have the bootloader locked and also LG UP (The tool used to flash the firmware) wont let you load the h918 firmware to a h910 because it will brick.
What you can do is install a custom rom like linage os that will enable wifi hotspot and most of the AT&T locked stuff.
(Note:There is no current way to get back to stock on the AT&T Variant (H910) )
after flashing this ROM to my phone via Odin
N910PVPU5DQI5_N910PSPT5DQI5_N910PVPU5DQI5_HOME.tar
i get this message when i try to call:
you are in domestic roaming and charges may apply per plan.
ad in most cases the phone cannot detect the network (i have a GSM sim and not CDMA)
what to do? should i change this firmware? (i think this firmware is for sprint in America)
i have same firmware, i am in Argentina and i don`t know if 4g works... have you find any fix to your problem? it is possible to root ? or maybe is it possible to roll ack to older versions and do all this?
Is it possible to modify which network bands a device communicates with by using only an app? And can that modification be permanent enough that flashing stock firmware through Odin doesn't restore it?
I got a bit carried away and was trying to get my Verizon S7 to become a strictly an At&t variant forcing it to register on GSM. Really, I have no clue what I was attempting, but now it takes several attempts to send text messages before they actually send. No problems with anything else except sending SMS. Before it will send, the phone will switch from 4G XLTE to N/A, then back again. I've tried different messaging apps, different SIM cards for Verizon and Cricket, and I've flashed multiple stock firmware all with the same results. My SIM cards in other devices work fine, but I've screwed this S7 up enough that its driving me crazy. Any help would be greatly appreciated. Thanks.
Did you try flashing the U firmware over the V phone? It worked for me.
Don't flash the AT&T one - not sure about Oreo, but the Nougat version of AT&T has a different boatloader (5) and it cannot be downgraded later to the 4 of the other versions.

Hi,
I have a Samsung S8 Active G892U which I bought used as an unlocked phone. It's clear it was originally a Sprint phone, but I have been using it with no problems on T-Mobile USA. It was running firmware G892USQS3BRI1 until today
Today I was prompted to install the latest software update ( G892USQS3BSA1 - this was clearly a Sprint update; it appears my phone is still getting Sprint updates, which makes sense, as it has Sprint firmware).
There was a warning on the Software update screen that the update would stop Volte working, and I would therefore no longer be able to access data while in a phone call. I (foolishly!!) assumed this would not affect me as I was on T-Mobile. I regularly use data while on the phone, so I know there was no issue with this previously.
The upgrade has completed, and I can no use data while making a call (I am in a LTE area at the moment). There is no sign of any option to enable or disable Volte anywhere in the settings menus
I did try going into Settings->Connections->Mobile Networks and changing Network Mode from "Automatic" to "LTE/CMDA." (as various forums indicated that doing that would provide a menu where I could re-enable volte)
This made the situation worse - I could no longer make calls. I have changed back to 'Automatic' , and can make calls again, but still loose data connectivity when making a call.
Is there any way I can restore my previous ability to use data while calling?
I am wondering:
a) If there is a way to renable Volte without reflashing the phone (that would be preferred)
b) If I do flash the phone, what would be the best firmware to go to - Sprint (presumably the previous version), T-Mobile or something custom (I'm clearly concerned about bricking the phone here)
c) It's several years since I've found myself re-flashing a phone - I see lots of references to "Odin" as the tool to use - is that correct, and could someone point me to the best guide on using it?
Thanks in advance..
You can flash the Sprint latest firmware over the current firmware and I think that should do the trick because I did it and so far so good but proceed with caution I have no experience in dirty flashing but as long as you just stick to the AP file and don't load the bootloader etc I think you should be safe from bricking because as far as I know when the boot loader is gone you can't repair anything
