I have a model S20 SM-G981U that is carrier locked to SPR. But it was flashed to the latest Metro rom with Odin accidently. My ultimate goal is to carrier unlock the phone.
Now with the Metro rom, it doesn't come with any carrier unlock app to unlock the phone. I tried flashing the phone back to Sprint using the following ROM:
Download SM-G981U / Galaxy S20 5G SM-G981U SPR in Samfw - Samsung firmware download
SM-G981U / Galaxy S20 5G SM-G981U SPR samsung firmware download all model, lastest, fast update, completely free and fast speed in Samfw.com ✅
samfw.com
Odin shows that the flashing was successful, and the phone was successfully factory reset after the flash.

However, the phone still shows that it is on Metro after everything is finished:
What am I doing wrong??
TIA for any help or advise you can give.
The phone detects the CSC to use from the SIM. Do you have Metro SIM?
Oh that was a brilliant suggestion, ShaDis. I had hoped that it was the case. I just removed the Sim card that was in it, a Cricket Wireless sim, and tried reflashing the phone and the same thing happened It's still showing the Metro logo when the phone starts and the same "TMK/TMK/SPR" as the provider software in the Software info screen.
Did you ever get a solution to this issue? I have the same problem with an accidental metro pcs flahs. Thanks
I do not understand what the problem is. Update was successful. What is wrong?

There's no such thing as an "accidental metro pcs flash". The Metro model has the exact same model number as the Sprint model, and the firmware is also identical.
Since T-Mobile bought Sprint, Sprint's devices have automatically been made compatible with T-Mobile. That means that when you insert a T-Mobile SIM into a Sprint device (even if it's still SIM locked), it's gonna give you the popup prompt to "reboot to apply new carrier settings" (as if it were SIM unlocked). That's because it no longer needs to be unlocked in order to be used on T-Mobile.
And, since T-Mobile owns Metro, the same thing probably goes for a Metro SIM.

I found out that they all use the same flash firmware files. When the phone detects a sim card in it, it would show the appropriate carrier's logo. My phone was locked to Sprint previously, so I couldn't get it unlocked by calling T-mobile. So I'm stuck with a phone that will only work with T-Mobile

I was on the phone with T-Mobile customer service for a couple of hours and they kept transferring me back and forth. I gave up with T-mobile. Are you that wise man who knows the answer to my quest?

Hey guys I need some help with Sprint. I recently purchased a couple of S2's for my kids from a guy who had Sprint and switched carriers. One connected fine, the other did not. Sprint says it is a problem within their system not being able to connect the ESN to a Sprint number but the phone is definitely a Sprint device. It's not rooted and it's not flashed. They have a ticket open on the issue but they are taking too long. Is there anything I can try that might fix this?

You can Odin a Sprint Stock ROM. It won't trigger the flash counter or change the device status to modified, all of the stock ROMs are located here-http://forum.xda-developers.com/showthread.php?t=1903252
Just follow the instructions in the thread of the ROM you pick. (GB27 is the latest Sprint ROM) it sends you to. PC required. But you may have to change the HA and AAA keys to get it to work if it was flashed to another carrier. And further yet it may have been flashed to another because it had a bad Sprint ESN. If that's the case you won't be able to activate it on Sprint... It will work on Boost, FreedomPop, Ting, Page Plus, Straight Talk, or Virgin Mobile if flashed. Just giving you as many possibilities as I can think of.

I'll try to Odin again. Right now it is on the latest Sprint GB27 so I'm not sure what the issue is. But I'll give that a shot. Sprint verified the ESN is not bad, Has not been reported stolen or lost or anything like that. I would think that if it was flashed to another carrier that it would not be on GB27 correct? It would have to be a Cricket Rom or Boost Rom etc...
The only other carriers that have ROMs are Boost and Virgin Mobile, but technically you can use a Sprint ROM with any of the carriers mentioned above, all you have to do is change the mmsc url and apn settings. They all basically run off of Sprint's towers.

Ok I'll look into that also. I'll do some comparisons with the phone that worked and the one that doesn't
Doesn't make any sense that they can't activate it on their end if it has a clean ESN
Hi,
I bought brand new inactivated sprint htc one m8 harman kardon. I managed to get it bootloader unlocked, S-Off, rooted, and TRWP 2.7.0.2. I'm trying to get the SIM unlocked but I couldn't. I used the following method to unlock the sim but I couldn't pass step 4 as I reach to hit "start" but nothing happens. (http://forum.xda-developers.com/showthread.php?t=2718150&page=5)
I also tried to install roms but when the mobile boot after I get successful installation, it reboots on bootloader screen only.
I appreciate any help.
Thanks.
you do realize that post you linked to right at the top it says 100% works from GSM unlocks. nowhere does it say anything about CDMA phones...? which your sprint model is...
and yes i know what your going to say it has a GSM sim card slot but it doesnt matter.
when people say compatible with GSM models it mostly means international GSM and US(ATT/TMOBILE) phones. CDMA phones are a bit more complicated. cause theres the extra CDMA radio partition.

you dont need to unlock the SIM in order to use custom roms. all you need is to unlock the bootloader using the HTC unlocker

I did unlock the bootloader in addition to S-Off. However, I'm not able to install any rom. After I try to install the rom (zip file) and I get the message to rebbot after I get successful installation, it boots back to bootloader screen!

It seems to phone is unlocked, i don't know what to do right now!
any help? please, thank you in advance
I have a solution. Open your phone dialer and type this code
##72786# and press the dial button and the phone should restart. I live in India and when I upgraded from Kitkat (custom rom) to Stock Marshamallow, I also lost the network. But after trying the above method, I got the network when the phone restarted. Hope this helps you. BTW I am on a GSM SIM.

My so called 910F ( actually 910p) having the same prob.
I purchased the phone SM-N910F in Bangladesh but actually it was refurbished SM-N910P rooted and masked as 910F with a stock software. However, I have flashed it with the stock rom N910PVPU4COG5_N910PSPT4COG5_N910PVPU4COG5_HOME.tar.md5 it worked fine. It started then OTA update and when updated to 6.0.1 android ver. it lost network. I input the command as above (##72786#). Now network is working but network bar is showing empty and now the set is working as digital roaming and roaming sign (r) is showing with the network bar.
However, thanks for the help, it least the phone is working.

Picked up a used AT&T Note 5 recently, everything works except it won't connect to the T-Mobile network. I had previously bought a used(white) AT&T Note 5, factory reset it, put in my t-mobile SIM and bam, I'm up and running.
But with this (black) one I've tried just about everything, adding APN, check IMEI, etc....no dice. Even tried the T-mobile customer service. They tried & checked everything, no go. They even saw the device history and it was running on t-mobile just a couple months ago with the previous owner. I've even ran a ping test and turned the radio off & on in the diagnostics *#*#4636#*#*.
After investigating other threads it seems it could possibly be Marshmallow PE6 that screwed up the radio? But I would think it had been running on that previously.
Any other ideas?

Just try downloading a different firmware(older) and pull the modem.bin out of the tar file and then re-zip it again into a modem.tar file so it can be flashed with odin but don't try going to far back like if you're on Marshmallow don't try flashing a modem from Lollipop because it won't work.. I use 7zip for the extracting and zipping of files.
Well, the plot thickens.
When I checked the IMEI before purchase on Swappa it said all was good. However, they couldn't identify the type or provider of the phone. I didn't think much of it at the time. So I decided to double check the IMEI on a different 2 other checking sights last night and I got the following info(from both!):

Clicked "Network Check" and it said: "IMEI not found on database."
Wtf? Can this be fixed? Is this causing my network issue?
I also checked the IMEI on the back cover, and it states it's clean, not blacklisted and is for an AT&T Note 5.
Anyone restore an IMEI?

Messing with the IMEI is illegal! Are you sure you didn't buy a fake phone? Do you have a picture of the front of the phone?

Download an app called phone info from the play store over wifi and see if the settings match what they're supposed to for the phone. Is there a sim card in the phone?
http://m.gsmarena.com/samsung_galaxy_note5-7431.php
Yes it recognizes the SIM but still, no network found.
Cosmetically nice phone, guess I'll re-sell for parts.
Thanks anyway, appreciate the responses.
For tmoble you have to unlock it.
Hey,
I bought an LG G7 ThinQ (LMG710TM) in the USA, and i does not connect to the LTE/4G mobile data network here in Hungary. Since it's a T-mobile version i thought if i could unlock it, it may work (i can use my Telekom SIM since the beggining to call/send msg), but i can't get the unlock bin trough LG site, because it says it's an LMG710TMP version which is unlockable, but the phone itself says it just te TM version withouth the P on the end.
Anyways should I even bother to try to unlock it, because i didn't really find any infos which frequencies are supported by my own device, so it maybe just blocked by the software or not.
Thanks!!

It's not rooted right?
Enter the service menu and check the bands. If it says "SUCCESS" then that band is supported. If it says "FAIL" it's not.
Bands 2, 4 and 12 are the ones usually used with GSM LTE in America.

And yes, it's not rooted.
I checked the service menu, the listed(pic1,pic2) bands are all working, at least it said "SUCCESS" when i clicked on them, and in Hungary they use band 3,7 and 20.
I set it on 3, tried to reinsert simcard and restart phone, and airplane mode etc,etc little tricks to get it work, but still no mobile data.
The weird thing i found is the LTE Carrier Aggregation(pic3,pic4). It says what is says on the picture and i can't change it, because it tells me i need to restart my phone. I did it but no changes, so it just stuck at those options. I suspect the problem is there for some reasons that i don't know.
On pic5/pic6 those are some infos about the LTE stuff, sometimes it said Not Supported Mode at the Mode Pref, sometimes it said Automatic. Sadly i don't really know what that means, maybe it will provide some infos to you.

Did you contact the mobile provider and ask them to add your phone's IMEI to their service?
In USA, some people who bought the LG unlocked international phones did not have mobile data until they called the carrier and had them register the IMEI number.
You'll most likely need to setup your APN manually. Go to settings-network and add APN info for your provider there!
