Hey everyone!
So, I own a LE2115 OP9 5G and it is currently operating stock OOS 12, I have no issues with it, I've run multiple custom ROM and have rooted it from the beginning. My issue is this:
I currently use Metro by T-Mobile as a carrier, I wanted to switch carriers and as it is network unlocked from the factory, I assumed that it would be good to go as far as switching it to a Sprint/T-Mobile acct. Apparently, they "Sprint" is having some sort of issue activating the SIM because it is international FW. Could I possibly change my FW variant to T-Mobile and solve the issue? If so, can I do that using an MSM tool? If anyone has the solution, I'd really like to be instructed how to fix this. I love the device, and it's just strange that I cant get it to work even though Sprint and T-Movile and Metro by T-Mobile should all be the same. Thanks in advance!

Hello, just upgraded from a Galaxy S4 on T-Mobile to an unlocked Verizon HTC One M8 handset. Popped in the sim, I can send and receive text, data on HSPA/3G mode but not one LTE or Global mode (anyone know why this is? I'd like to be able to use t-mobiles LTE and not just HSPA/3G), get the usual "sim unknown source" stuff. I am wanting to flash Skydragon.
My question, is there anything special I need to do before/after I flash these, since I'm using a different network than what the handset was originally supposed to be on? Maybe I need to flash different radio? This is my first time using an unlocked phone, previously all my phones with custom ROMs were on the same network as the handset variant.
Otherwise, would I just update to the latest 5.0.1 OTA update from Verizon, root/unlock bootloader, install TWRP, then flash Skydragon, and I'm all good?
Edit: Well, further reading seems to indicate to me that it turns out verizon M8 devices already updated to 5.0.x are still not able to be rooted at this time?
Thanks for the help
Hello, All. I was wondering, if I got my Ocean carrier unlocked at Walmart, which of these would be the firmware it is on? Is there a way to know?

Thanks for any help.
The best way to check'd be going to Settings, System and about phone. Software Channel has the prefix code you should download from.
Too late for that now, lol. I flashed the Metro (since I'm on Metro) but there are no carrier apps and I can't tell the difference.
I have a T-Mobile OP7 pro that I've had unlocked from the network, and I've been running the international version of OOS for some time. This week I tried changing to Havoc OS (because I've used it on previous phones), and now I'm stuck in a bootloop. I don't even get to the ROM's boot screen. I know I can put factory software back on there, but I'm not ready to give up unless someone here knows whether it's impossible to run AOSP ROMs on a T-Mobile OP7 pro.
You're better off converting the phone into the international variant using the MSM tool. I have a converted unit, and all ROMs work properly after conversion.
A question from a noob here. I have a T-Mobile S22 Ultra phone which is network unlocked. As I recently I switched from T-Mobile to Verizon, I'm missing some of the features that are Verizon specific, while not needing anything that is T-Mobile specific anymore. From what I understand, Samsung installs multi SCS firmware on most of the phones these days, which can be changed by a dialer code. That however did not work at all.
Another option I've come across is by flashing provider specific (in my case Verizon) firmware as long as firmware version is the same (S908USQU2AVDC). There are a number of articles on how to do it by using Odin. The issues is no matter what I do and what files I select (like by using CSC file instead of HOME_CSC with or without flashing USERDATA file as well) the result is the same. It shows success and reboots and then reports an error and does the full factory reset which ends up back on T-Mobile version.
The question I have if it's even possible? And if so what I'm doing wrong here. Unlocking a bootloader is not really an option for me...

In theory, flashing the correct firmware (VERIZON) should work. I would honestly first wipe the device, then flash (clean, not dirty) the Verizon firmware and setup accordingly. I had a similar case with a TMBILE unit (I had changed carriers) and I had managed to use XAA CSC and then when I reverted to TMOBILE SIM it would not "restart and install carrier updates". I had to basically switch the unit to U1 and then revert to U and it finally pulled all the TMO crap.
I may be mistaken since I haven't done this type stuff since S10, but I think you need to first reset the device and flash the unlocked version then when you put the verizon sim in it should provision it. Then you can flash the verizon package if you want the bloat apps. The features may be hit or miss. You may need to activate the features on the verizon website. Some features may never work as the carrier wont push them to IMEI not in their database of branded phones. There may be things you can do in hidden settings with "Activity Launcher" or other methods.
I'm here trying to figure out the same things for Tmobile and a factory Unlocked phone, before I buy.
Thanks a lot for your suggestions guys! I managed to do what I wanted. This is what I ended up doing, first flashed the unbranded U1 version on my phone and on the first boot Verizon sim was provisioned. Then I flashed Verizon firmware and it worked!
Hi all,
Anyone tried to burn a SM-F721U1 device with sm-f721u firmware?
I remember doing it on a note10. Question is if it's still possible?
seems to flash just fine. I have only found tmo and u1 with july patch... are there others?
I tried. Mobile network get disabled. Grey out in status bar. I am using US Mobile services. I have to do a fresh flash A12 VZW build to get back working handset.
I was wondering this as well. I purchased my first unlocked phone and now I wait for the 13 update, while the T-Mobile version is already out. I am on T-Mobile, so I'm guessing it will work just fine. Will my phone still be "unlocked" if I flash the SM-F721U firmware?
